Abstract

The invention relates to a vascular manometer with flow sensor for measuring blood pressure in the surface veins and arteries of humans and specimens, by applying a regulated force to an area proportional to the diameter of the measured vessel. Heart rate, blood flow and cardiac rhythm are determined using Doppler analysis. The invention comprises a cylindrical body with a lower distal end provided with a sensor and an upper end provided with an electromechanical control box. The invention is formed by separate components consisting of three units, namely a control box, a connection cable and a probe. The invention also includes a Doppler motion sensor system and an electronic spring motion or pressure sensor with graduated force for emitting a pressure reading determined by an analog, digital or mercury column manometer. The blood flow is listened to and recorded when the force is applied to the artery or vein in order to determine the aforementioned measurements.

Description

Vascular manometer with flow sensor applicable to measuring blood pressure in arteries and superficial veins of humans and specimens

DESCRIPTION

OBJECT OF THE INVENTION

Measure the blood pressure in arteries or superficial veins with a non-invasive method in people or specimens of any weight, size and age.

BACKGROUND

At present, a sphygmomanometer consisting of 4 main parts is used to measure the systemic blood pressure with an indirect non-invasive method, which can be detailed as a bracelet consisting of a balloon lined by a rectangular plastic or fabric connected to a insufflated hose by one end, ending is in a blower knob and a pressure transmitting hose on the other that ends in a conventional digital manometer, mercury column or the like and is [original of a Russian named Korotkoff who in 1904 observed that auscultating the brachial artery in an immediate distal portion to the lower edge of the cuff, when it is inflated, the pulse is not heard and as it deflates, the sounds of the arterial pulse reappear more and more audibly. The moment of beginning of your hearing is considered the level of systolic pressure and when they disappear completely, the level of diastolic pressure. (Dr. Jesús Vargas Barrón 2006, Treaty of Cardiology, Mexican Society of Cardiology 1st Edition Editorial Intersistemas SA de CV, Chapter 2, p.19)]. Several devices (sphygmomanometers) are known to determine the blood pressure and all have a digital mercury or analog column device [the technique provides that the bracelet should cover approximately 2/3 of the arm or thigh, and the width of the bracelet should be 20 % greater than the member diameter. A sleeve that It is too narrow can lead to falsely high measures. A handle that is too wide, can produce false low values. Non-invasive blood pressure measurements involve the occlusion of an artery by a pressure handle and the measurement of oscillations in the pressure handle or the pressure at which the flow through the artery reappears as the cuff is deflated (Jon Walsh and Randall DuII Ed. Marban 2001, Massachusetts. General Hospital Intensive Care Chapter 1 Hemodynamic Monitoring).] The conventional technique of 1904 has been useful but is inaccurate and deficient because in said method the pressure of the artery is not determined explored, but the index of compressibility of the limb segment in relation to the occlusion of the artery, whereby who subscribes Dr. Jesús Bustillos Cepeda on August 20, 2005, starts the thesis as of the date currently being developed at the University Autonomous of Tamaulipas, Faculty of Medicine, with Alternative Title in determination of the Arterial pressure with increase in sensitivity and specificity. Where in preliminary results I have observed statistical significance in favor of the vascular manometer between the values of the real pressure of the artery explored by the vascular manometer with the new technique, compared with the sphygmomanometer using intraarterial catheter control in dogs. In humans, the comparison between the new technique with Vascular Manometer and the old technique with sphygmomanometer shows a significant increase in sensitivity and specificity in favor of the Vascular Manometer, even more so we have not evaluated it in humans with intraarterial control. From the history, medical practice and preliminary of the thesis in evolution in this regard we can deduce 1- The sphygmomanometer determines the blood pressure plus the compressibility pressure of the tissues that surrounds the bracelet and this sum gives a significant error. 2.- The same range of brachial perimeter in people with variables of age, weight, height, normal, atrophied or hypertrophied is different from the pressure of the original brachial perimeter and the final brachial perimeter at the beginning of the turbulence (We consider beginning of turbulence at the beginning of obliteration of the artery), whereby we have significant error in the determination of blood pressure by conventional sphygmomanometer.

3.- Due to the design and technique of the Sphygmomanometer Ie it is impossible to assess the blood pressure in arteries of flat bones and irregular surfaces as well as in superficial veins.

4.- In a graph of age, weight, height, and sex, the Sphygmomanometer increases its margin of error as the person withdraws from the male sex from 18 to 35 years, 1.65 to 1.80 mt. 65 to 85 kg Therefore, being a child, a woman, overweight, obesity, senior citizens, muscular atrophies or muscular hypertrophy gradually increases the error in the sphygmomanometer.

As you can think of the bias and limitations of the sphygmomanometer is found in circling the bracelet on the limb, hugging all types of tissues without taking into account the modulus of elasticity of the same. In addition to applying the pressure on a fairly wide surface dissipating the force in the entire circumscribed area.

With the purpose of reducing the margin of error in the determination of blood pressure and exploring other arteries and veins of diagnostic importance, a new technique and the development of the Vascular Manometer were thought, which is intended to be protected by means of the present application and which determines the blood pressure with a new technique and greater efficiency than the sphygmomanometer.

The electromechanical control box No.1 is typical of the Digital Manometer fig. 3. in its 2 presentations in its mechanical presentation or with graduated spring No. 15 or by electronic pressure sensor No. 61. In the case of the Analog Manometer it may or may not be presented in the vascular manometer of liquid column. Which is attached by internal thread to the neck No. 2, connected by internal thread to the top threaded and perforated top No. 5, connected by internal thread to the nightgown No. 9, connected by external thread to the threaded top and perforated bottom No. .26 that contains and allows the passage to the body of the piston with No.21 head which is joined by a reduction with jack system or quick connect plug by pushing and turning a quarter of a turn to the copy with lower reduction No.29 that joins through its threaded reduction to sensor No.33. It can be all these parts of metallic material, ceramic plastic or any other that meets the principles of quality. The description of the Vascular Manometer is addressed to the Vascular Manometer in the Digital Modality with the pertinent clarifications of the Analog Manometer and Column Manometer during the description of its parts and in its respective section. The Vascular manometer has a rocket shape with a tip in the No.33 sensor, being able to adopt any other as is the case of separating the transducer screen connected by a telephone cord. The Vascular Manometer is characterized by presenting a spring system, or a force application system in a tubular, cylindrical or tablet-shaped electronic analog device or another form that could be adopted for quality improvements to determine the arterial pressure! or venous, It has the peculiarity of applying Ia pressure by means of a No.33 sensor which may or may not be divided into two anterior and posterior parts for its manufacture joined by 4 No.36 screws. Which inside houses a pressure sensor analog electronic conversion. This No.33 sensor can be a changeable unit for a quick Jack type connection because it has variable dimensions on its lower side No.34 of 0.5, 1, 1.5, 2 or more cms. Or fixed by means of a sensor of standard dimensions, Depending on the diameter of the artery or vein to which force will be applied, the unit used in the case of specific sensitivity, the sensor No.33, on its upper face No.34 in the hole that Io crosses concentrically and longitudinally starts with a larger diameter and with internal thread to accommodate the threaded lower part of the copy with reduction with lower reduction No. 31 also with longitudinal hole that houses the duplex fixator of extensions No. 32 in its upper portion. In its lower face the sensor No. 33 has the exit of the hole that crosses it longitudinally and houses the duplex fixator of extensions No. 32 in its lower portion, this can be plastic material or any other insulator since that is its function, it is of cylindrical shape with two holes that cross it longitudinally parallel to house and isolate the fiber optic extensions No.53 which serve as extensions of the piezoelectric crystals or emitter and receiver optical sensors No.20 that are housed in the duplex crystal fixer No. 25, which is completely cylindrical outside threaded and crossed longitudinally by two parallel holes of Vakelite plastic material or other insulating material, the external thread Ie serves to be assembled in the threaded hole lower face of the piston reduction with head No. 24 Piezoelectric crystals or optical sensors emitter and receiver No.20 Any of the 2 can be useful hoisted, isolated laterally from each other by vakelite, plastic or other insulator, these may be photo emitting diodes or emitting glass and photoreceptor diode or receiving glass respectively which receive or emit signals externally by the fiber optic extensions No.53. at the same time they receive or emit signals from the logic electronic card No. 37 at its receptacle point, the transmission line of piezoelectric crystals or No.49 emitter and receiver optical sensors via afferent and efferent transmission line No.19 consisting of concentric cable with maya shield or other material applicable for this function. In the case of the digital model of Figure 7. the electronic pressure sensor No.61 adheres to the piezoelectric crystals No. 20 on its lower face and is crossed by axial cables No. 19, the cables of the electronic pressure sensor No. 62 and the axial cables of the piazo electric crystals No. 19 end in a coupling cell that communicates the signals to the microprocessor of the dopler and the pressure sensor No. 64 in turn this communicates and receives signals through the microprocessor lines to microcontroller No. 65 in the logic electronic card to process the sound information transforming it to Heart Rate defined as the number of beats per minute, Heart Rate defined as the ratio of the duration of each of the beats in 60 seconds, from that the noise starts until it ends, plus the silence time, ending at the point where the next noise starts. Blood flow determined by the diameter of the vessel and the acceleration of the blood, or represented by the amount of noise in decibels systolic blood pressure given by the measurement of the Compression Tension of the artery or vein until occluded and at that time the force of The blood that bursts said occlusion will be systolic pressure, the application of force is given by Sensor No. 33, and Diastolic Pressure. It is the blood pressure at the moment when the pressure on the vessel decreases the turbulence disappears. Venous Pressure is the pressure recorded at the point of occlusion of a vein. The copy with lower reduction No. 29 is cylindrical and has two ends threaded lower part of the copy with reduction 31 as already described which continues with the sensor 33 and the upper part of the copy with reduction No.30 as every cylinder has an edge and on this 2 symmetrical rectangular grooves facing each other in the center a hole that crosses it longitudinally and in the raised walls that give the lateral edges to the grooves in its inner face have two symmetrical grooves with a straight and elongated triangle in its hypotenuse and adjacent leg to form the female connection of a quick connect jack or plug system and by pushing and turning a quarter turn it joins the lower part of the piston reduction with head No. 23 which at its sides symmetrically presents a triangular shaped projection to anchor with the female jack system as described, also has a threaded hole in the lower face of the reduction of the piston with head No. 24 to accommodate the fixator Duplex of crystals No. 25 containing piezoelectric crystals or optical sensors emitter and receiver No.20, by means of the Jack or plug junction, the sensor unit No.33 of the desired caliber can be assembled By mechanically orienting the elements of light or sound piezoelectric crystals or optical sensors sender and receiver No.20 duly coupled when inserting the lower part of the reduction of the piston with head No. 23 in the super part ior of the copy with reduction No.30 the orientation in the beginning would be 90 relative degrees and when inserting the male receptacle to the female pushing head downwards until finding the final stop position of the depth only at that moment will we rotate 90 degrees in the direction of the clock hands thus finding the light or sound conduits that correspond to each other in the order emitter with transmitter and receiver with receiver remember that the optical fibers in the heads are the extensions of the signal elements that will intervene in the measurement of the parameters , it is for this reason that we can change the sensor No. 33 according to the caliber of the vessel we wish to analyze. In a complementary way it is possible to use other alternatives to collect the emission and signal collection so we are proposing a double bayonet receiver emitting terminal with two poles each which will also be inserted with a jack or plug system. The piston with head No. 21 has in its upper part a head that serves to support the graduated spring No. 15 graduated in the direction that each mm. compression represents n grams, and the force transmitting rod No. 16 and its main function displaces these structures up or down depending on the application of force, the head proper of the upper part of the piston with head No. 22 on its lower face meets the inner stop of the bushing No. 14, while the movement from bottom to top and reverse the side edge of the head slides on the inner face cylindrical of bushing No.11, ending its displacement downwards when it encounters the lower face of the head on the internal stop of the bushing No.14, while the piston body with head No.21 moves through the central hole of The lower face of the bushing No. 14 and in the central hole of the threaded and perforated lower cover No. 26 The piston with head No. 21 is crossed from the upper end to the lower end by a cylindrical bore that allows the transmission lines to pass afferent and efferent No.19. The bushing No. 1 1 is made of Nylamid material to prevent friction of metals, it serves to fix the graduated spring No. 15 which has the function of presenting graduated resistance to compression to such a degree if it is pressed by the piston with head No.21 displaces the No.16 force transmitting rod in which the distance traveled in relation to the force applied in parallel to the spring compressed by the piston with head No.21 will be observed. The piston with head contacts the internal walls of! bushing No.11 where it travels and from above is covered by the threaded and perforated top cover on its inner face No.7 assembled in the nightgown No.9 and below with the internal face of the threaded and perforated bottom lid No. 27. In the case of the liquid column pressure gauge No.1 c the piston with head No.21 during the upward movement presses the chamber of synthetic material No.42, sized inside the bushing that contains air and this is propelled towards the hose to transmit air under pressure No.54 and from there to a conventional graduated column of alcohol or other liquid mercury to determine the pressure in the graduation in mmHg. The internal face of the threaded and perforated lower cover No. 27 encloses the bushing No. 11 when joining the lower part of the nightdress No.10 allowing through its lower hole the passage of the afferent and efferent transmission line, the nightdress No. 9 is a hollow cylinder with 2 ends that houses the hub 11 inside, encapsulating Ie together with the graduated spring No. 15 and The piston head No.22 in the upper part of the nightgown No.8 is assembled with the internal face of threaded and perforated top cover No.7 to support the graduated spring No.15, and allowing the passage through its central hole to the afferent and efferent transmission line No. 19 and the dipstick No. 16. The internal face of the upper threaded and perforated cover No. 7 In the case of the analogous manometer, it serves as support for the graduated serrated spring No. 45 and the afferent and efferent transmission line No.19.

The internal face of the top 7 threaded and perforated lid in the case of the liquid column manometer serves as the upper support for the chamber of synthetic material No.42 and through its central hole allows the passage of the afferent transmission line and efferent No. 19.

The external face of the threaded and perforated top cover No. 7 has a 1/3 threaded top to be assembled with the neck No. 2 of the Vascular Manometer and through the central hole gives way to this cavity to the afferent and efferent transmission line No 19, and to the force transmitter rod 45, in the neck No. 2 in the case of the digital pressure gauge the force transmitter rod No. 45 joins the photosensitive electronic cell No. 17 which is graduated from or to 300 a such a degree that each of the 300 photosensitive regions represents a mmHg so that when it is displaced by the transmitting rod of force No.45 in the top-down or inverse direction a diode laser emitting diode No.18 Ia stimulates since it is fixed in The wall of the neck No. 2 and with the light beam towards it to stimulate the graduated photosensitive regions and thus it transmits the information through the transmission lines of the photosensitive electronic cell to the receptacle No. 48 of the ta Logic electronic card No.37. The laser photo emitting diode No.18 is attached to the wall of the neck No.2 and receives the energy through a power supply cable for the photo emitting diode laser No. 58 that ends in the receptacle No. 50 thereof name in the electronic logic card No. 37 Ia which has the characteristics of generating and receiving signals with light wavelength or sound, electronic, emit digital commands and codes to the liquid quartz screen to generate the pressure measurement recording conditions. It features the following terminals Referendum of afferent and efferent transmission lines No.19, receptacle of transmission line of photosensitive electronic cell No.57, Power supply input of logic electronic card No.47, output for liquid screen Quartz for digital pressure gauge No.46 Output for communication interface No.62, Power supply cable terminal for laser photoemitter diode No.58, Output terminal for hearing aids No. 63. In the case of analog pressure gauge Ia No. 45 cogwheel transmission rod makes contact by mechanically assembling to the cogwheel No. 43 causing it to rotate in its displacement from top to bottom in the form of the conventional clock gear forming a mechanical speed differential that transmits acceleration to another smaller gear and it is on the hand of the graduated dial giving the measurement in millimeters of mercury. In the case of the liquid column manometer in its constitution, it has everything described above except electronic control box, force transmitting rod, toothed force transmitting rod, since its furniture system is constituted by the synthetic or rubber chamber No.42 which directly receives the pressure of the piston with No.21 head decreasing its volume and thus transmitting through the contained air the pressure to the liquid column that can be alcohol or other mercury to record in the graduated column the measurement in mmHg .

The electromechanical control box No.1 has a prismatic shape with 6 sides, its upper face has the power button No. which can be a membrane, rocker lever rotary switch. On its left side edge. It has a female input of communication interface No.39 and an audio output with speaker No.38 on its right side face has a female input for headphones on the lower face has a large hole with internal thread on its front face is occupied by Ia Quartz liquid display for digital pressure gauge No. 52 and in the case of the analog vascular pressure gauge by The graduated dial in the form of a clock with a hand, in the liquid vascular manometer may or may not present this piece.

The lower face has a hole with internal thread to join with the neck No.2 through the hole pass afferent and efferent transmission line No.19, Transmission line of photosensitive electronic cell No. 57. The electro-mechanical control box in its Inside houses the power source (battery) No. 40 and the logic electronic card No.37 and other transmission lines as already described. Specifically: The Vascular Manometer applicable to measure the blood pressure in arteries and superficial veins of humans and specimens applies a regulated force to an area proportional to the diameter of the measured vessel, and is characterized in that it is formed by a cylindrical body with a lower distal end which has a No.33 sensor and an upper distal end that has a No.1 electromechanical control box that has the power button and volume control on its upper face and that houses a motion sensor system and an inside spring system consisting of a No.9 nightgown that houses a No.11 cylindrical bushing with covers on both ends by the upper perforated threaded cover No.5 and the lower perforated threaded cover No.26 joined by the external threads on the extremities of the nightgown, the No.11 bushing inside allows the displacement of the piston with No.21 head, which presses the compressible element that is arranged in parallel to The pressure transmitter element that simultaneously moves to compression so that the force graduated in the compressible element is translated into distance traveled by a rigid element and in the case of fluids in displaced volume, whereby the rigid element transfers to the transducer system The pressure measured to manifest a pressure reading of 0 mmHg to 300 mmHg. In the case of fluids, the piston with a head pushes the flexible container that contains it by displacing the volume of the fluid through the hose to transmit air under pressure No.54 and this by means of a membrane pushes another fluid of greater density in a graduated column to determine the blood pressure or venous The motion sensor system is formed by a logic electronic card No. 37 connected to afferent and efferent transmission lines No.19 that end in emitting and receiving elements No. 20 respectively to emit waves with "n frequency" on the circulating blood and its reflection be captured and sent to the logic electronic card No.37 Ia which of this information emits sound waves through the speaker No.38 and the female connector for headphones No.42, also emits light waves, controls and digital codes to the female communication interface No.39 and liquid quartz screen for digital manometer No.52 so that when applying the force on the artery or vein we are recording or listening to the blood flow to determine the pressure with which the pulse overcomes the occlusion that is the systolic pressure and the pressure where the turbulence that is the diastolic pressure disappears as well as listening or recording the rhythm pulse frequency and intensity. Another peculiar characteristic of the Vascular Manometer is that the No.33 sensor is interchangeable since the tip of the No.35 sensor has the optical fiber extensions of the optical or dopler motion sensor and varies in its dimensions to apply the force in a proportional area to the caliber or diameter of the artery or vein in the shortest radius of these to the skin. The electromechanical control box No.1 on its upper face has the power button No.41 and the volume control No.59.

The Vascular Manometer applicable to measure blood pressure in arteries and superficial veins of humans and specimens. It is also characterized in that it has the dopler motion sensor system which is formed by means of a logic electronic card No.39 connected to afferent and efferent transmission lines No.19 that end in a piezoelectric emitting crystal and a receiving piezoelectric crystal No. 20 to emit waves with sound frequency on the circulating blood and its reflection be captured and sent to the logic electronic card No.39. The Vascular Manometer applicable to measure blood pressure in arteries and superficial veins of humans and specimens is also characterized in that inside it houses an optical motion sensor system which is formed by a logic electronic card No.39 connected to afferent and efferent transmission lines No.19 that end in a photosensor and a photoemitter No.20 to emit waves with luminous frequency on the circulating blood and its reflection to be captured and sent to the logic electronic card No.39 to be processed.

As mentioned we have 3 presentations that are described below. Digital vascular pressure gauge can be seen in figure 3 1a and figure 1 that the generalities already described are characterized in that the spring system is constituted by a No.9 nightgown that houses a No.11 cylindrical bushing with covers on both ends by the cover threaded perforated top No.5 and the threaded top perforated bottom No.26 joined by the external threads at the ends of the nightgown. Inside the No.1 1 hub, the piston displacement with No.21 head is allowed, which presses on a No.15 graduated spring that is arranged in parallel to a No.16 force transmitting rod attached at the upper end with a photosensitive electronic cell No. 17 graduated to be displaced up or down by the force transmitting rod No. 19 to be stimulated in its regions by the No.38 laser emitting photo diode fixed to the wall of! neck No.2 that is pointing at it simultaneously to the compression is displaced so that the force graduated in the graduated spring No.15 is translated into distance traveled by the photosensitive electronic cell No.17 and the laser emitting photo diode No.38 stimulates the regions covered of the photosensitive electronic cell No.17 which sends the information to the logic electronic card No.37 and this transfers the information to the liquid No.52 quartz screen to give the result of the measurement in millimeters of mercury to determine the arterial or venous pressure. It has an optical motion sensor system and / or dopler completely conforms as previously described The Analog Vascular Manometer No.1a is characterized with the same generalities already described and characterized because in the spring system constituted by a No.9 nightgown that houses a No.11 cylindrical hub with covers on both ends by the upper perforated threaded cover No.5 and the lower perforated threaded cover 26 joined by the external threads at the ends of the nightdress No.9 Inside, a bushing No.1 1 allows the piston to move with a No.21 head which presses on a No.15 graduated spring that is arranged parallel to a No.44 toothed transmission rod that engages a wheel Toothed No43 clock type at the upper end for when the No.44 toothed transmission rod has a downward or reverse movement of the No.43 sprocket, rotate by rotating to another wheel of smaller caliber Ia which will be calibrated with the hand of The cover so that the force produced in the compression of the graduated spring No.15 is translated into revolutions of the hand on the properly graduated cover. The optical motion sensor or dopler system is completely shaped as described. The Liquid Column Vascular Manometer Figure 1, 1c, Figure 5, No. 45 with the generalities as described above and characterized in that in the spring system consisting of a No.9 nightgown that houses a No.11 cylindrical bushing with covers in the two extremities by the upper perforated threaded cover No.5 and the inferior perforated threaded cover No.26 joined by the external threads at the extremities of the nightgown No.9 and above it is articulated with the neck No.2 of the vascular manometer, continued the electromechanical control box No.1 modified to a simple cover. Inside, a bushing No.11 allows the displacement of piston No, 21. Nightgown No.9 presents the peculiarity of having a hole laterally in which the quick connect connector for hose No.55 is housed, Nightgown No.9 houses a cylindrical bushing that presents the peculiarity of having a hole laterally to give continuity to the side hole of the nightgown with head No.9 which presses the chamber of synthetic material or rubber sized to the walls of bushing No.11, the chamber of synthetic material inside has air at atmospheric pressure to be calibrated in O mmHg and when compressed, boost the force to a mercury column No.45 to move it against gravity to give the result of the measurement in millimeters of mercury and thus determine the arterial or venous pressure. The optical motion sensor or dopler system conforms completely as already described. The work efficiency of the Vascular Manometer is that the No.33 sensor is interchangeable since the tip of each No.33 sensor is proportional to the diameter of the artery or vein to be measured and the application of force occurs only in the area adequate object to measure. This application of force that transmits the sensor No.33 to the measuring vessel by means of the spring system already described. The pressure and flow information captured by the sensor is transmitted respectively to the manometer or logic electronic card to give the measurement reading and flow noises.

The advantages of the Vascular Manometer are:

1- The pressure of veins and arteries is determined due to the application of force on an area proportional to the diameter of the arteries or veins explored giving greater sensitivity and specificity to the measured pressure.

2.- Measure the blood pressure regardless of age, sex, size or weight in humans and specimens.

3.- Measure the blood pressure on flat bones and irregular surfaces as well as on superficial veins. 4.- The relationship between systolic / diastolic pressure, rhythm and heart rate is observed.

5.- It can be observed when determining segmental pressures in homologous arteries decrease in caliber due to various pathologies or alterations in blood flow and pressure. 6.- They have three presentations by the way of manifesting the measurement of the analog digital pressure and in a liquid column

For all that has been said above, it can be affirmed that these characteristics of determination of arterial and venous pressure have not been achieved by any other similar artifact and gathers in itself the characteristics to determine the pressure in humans and other specimens of any weight size sex and age .
