Description

Epi checkpoint

The present invention relates to an epi checkpoint, and more particularly, to be used in anesthesia of the lower body to suppress pain in the lower body of a patient, such as when a surgical operation is required, such as a caesarean section. The epidural (outer epidural) space of the spine When inserting an anesthetic needle or spinal needle into a part and injecting drugs such as anesthetics through a tube (catheter, catheter), detect the state in which the needle for cervical anesthesia is accurately located in the epidural space. It is about epi checkpoints that are input in a fast and accurate manner and operated digitally.

Anesthesia used for surgical operation includes general anesthesia, spinal anesthesia, epidural anesthesia, and the device used for epidural anesthesia or lower body anesthesia and digitally operated is called epidural confirmation device. Let's call it.

Epidural anesthesia is one of the anesthesia procedures used in cesarean section surgery known as painless delivery, lower extremity surgery for hip or knee surgery, pain relief after surgery, and outpatient pain clinic.

On the other hand, epidural anesthesia is an anesthetic drug injection in the epidural space (Epidural space), so the expression time of the anesthesia is relatively slow and there is a possibility of damage to the surrounding blood vessels.

1 is a longitudinal cross-sectional view of the human spine to explain the general structure of the dural structure of the body.

Referring to FIG. 1, the left part of the human body corresponds to the abdomen of the human body and the right part corresponds to the human body or the back of the body.

Epidural is located in the dorsal part of the spine, to the right from the center of the spine. The part labeled Dura is a structure called the dura. The epidural space, the right part of the dura, is the epidural space, and anesthesia is injected into the epidural space. It is epidural anesthesia.

Figure 2 is an explanatory view of the procedure of epidural anesthesia according to one embodiment of the prior art.

With reference to the accompanying Figure 2 is a state in which the epidural needle (epidural needle, cervical anesthesia needle) is inserted into the epidural space portion of the dorsal part of the spine and the catheter is connected. In general, the middle portion of the needle may be called a catheter, the needle for cervical anesthesia is more than twice as long as the catheter portion of the needle.

For this epidural anesthesia, the doctor pulls the patient's knee to the chest as much as possible, and the head maintains the posture of looking at the navel or the back, such as shrimp, so that the space between the spine and the spine becomes relatively wider.

The surgeon can relatively easily insert a cervical anesthesia needle or catheter into the epidural space with a relatively wide space between the spine and the spine.

Such an epidural anesthesia method is inserted into the surgical cervical anesthesia needle or catheter during the operation or even after the operation is completed to maintain the state as it is, so that additional administration of the drug is possible when the operation time is long. Has the advantage.

However, epidural anesthesia, unlike spinal anesthesia, is relatively complicated and the epidural space is relatively narrow.

In the epidural anesthesia method according to the prior art, a skilled anesthesiologist injects a cervical anesthesia needle manually or analogously between a vertebral bone and a vertebral bone of a selected number and connects a syringe to a catheter to inject physiological saline or air.

In this case, in the conventional art, when the injected saline or air is injected without resistance, it is determined that the end portion of the inserted needle is located in the epidural space, and this procedure is referred to as a resistance loss method.

However, such a method of resistive loss using the analog method is difficult to accurately position the tip of the injection needle for drug injection in the relatively narrow epidural space, depending on the skilled manual experience of the doctor.

In addition, the prior art has a problem that depends on the skilled sense of the doctor and the case that the injection needle for drug injection may damage the dura mater or penetrate deep into the dura mater.

Therefore, there is a need to develop a technique for confirming whether or not the end of the needle is precisely located in the epidural space.

The Korean Laid-Open Patent relates to a hypodermic syringe, comprising a needle body having a through-hole formed therein, and having a through-hole formed to penetrate from an upper portion of the needle body to a lower portion, and having a head portion formed on the upper portion of the needle body; A needle coupled to the body of the needle to puncture the abdominal cavity; An auxiliary handle coupled to the needle to facilitate gripping during abdominal cavity drilling; The needle portion is coupled to the needle portion, characterized in that consisting of a case to be stored in the state inserted in the inner side in the state coupled to the auxiliary handle portion to the needle, the end of the needle is formed to be bent to 20 to 25 The technical idea that only the effect of preventing damage to the epidural by the body can be detected, and the epidural space can be accurately detected by detecting the pressure difference of the epidural space is not described.

The U.S. Patent Publication is an apparatus for performing anesthesia or the like using a spinal canal to accurately find the spinal canal. Blood or spinal fluid (CSF) sucked into the needle in the process of inserting the needle between the spine (CSF) The present invention relates to a device capable of precisely locating the spinal canal by measuring the pressure of a fluid such as cerebrospinal fluid, and a main principle of the U.S. Patent discloses a syringe filled with saline to measure the pressure of the fluid. By doing so, it is possible to identify the position of the spinal canal by sensing the pressure applied to the saline filled in the syringe by the fluid sucked through the needle, which is a prior art document which has this main feature.

However, the U.S. Patent Publication is based on the principle of sensing the pressure applied to the syringe filled with saline through the injection needle, in the spine of the general public, as well as the spinal tube which is the main component of the spine, spine tube in addition to the presence of the spine There is often an empty space between them. In this case, the U.S. Patent Publication has a problem in that the needle can be detected as if the position of the spinal canal by detecting a difference in pressure even when the needle is located in an empty space existing between the spine instead of the spinal canal.

If the operator delivers anesthetics to the location of the empty space between the vertebrae and not the spinal canal, the procedure will fail.

In order to solve the problems and necessity of the prior art as described above, the present invention uses a constant pressure in the human muscle part (yellow ligament) and the phenomenon that the vacuum state is maintained in the epidural space part. An epidural confirmation device or epi checkpoint is provided for detecting pressure changes in the portion and the epidural space portion.

It is also an object of the present invention to provide an epidural confirmation device or epi checkpoint for detecting the state where the end portion of the needle for epidural anesthesia procedure is accurately located in the epidural space and displaying it as an audiovisual signal.

It is an object of the present invention to provide an epidural confirmation device or an epi check point for quickly and accurately confirming a state where an end portion of a needle for cervical anesthesia is located in the epidural space with a simple and easy configuration.

Epi check point of the present invention for achieving the above object is a digital method by directly measuring the pressure input from the body and the epidural space of the human body in an electrically insulated state and directly measuring the difference in pressure Transmembrane pressure sensor unit 1000 for outputting the electrical signal of the conversion; A dural pressure differential amplification unit 2000 for inputting the level of the signal detected by the dural pressure sensor unit 1000 and digitally amplifying at a set amplification ratio; Input the amplified signal and the amplification ratio from the dural pressure differential amplification amplifier 2000, respectively, and compares the reference signal stored in the state corresponding to the amplification ratio with a digital signal processing method and determines whether the value is large or small.

A dural pressure detecting housing part 8000 installed and fixed at a designated position and having a circular box shape; And a protruding cylindrical shape formed at a central portion of one side of the dura mater pressure detecting housing 8000 to input a biological pressure signal generated from the muscle and the epidural space of the human body and to transmit the dural pressure sensor to the dural pressure sensor unit. The government 9000 may further include.

The fixing fixing part 200 is formed of a polycarbonate material and has a handle protruding in both directions along a straight line, and the connection fixing part 9000 is inserted in one direction to the outer diameter of the connecting fixing part 9000 to be in close contact. A scale is displayed on the other side of the fixed support part 200, and a needle for cervical anesthesia 300 inserted directly into the epidural space of the human body may be installed.

The dural pressure differential amplifier 2000 may be configured to digitally amplify and output the level of the signal detected by the dural pressure sensor unit 1000 to any one selected from the range of 10 to 30 multiples.

The dural pressure comparison unit 3000 outputs a signal having a lower value than that of the reference signal when the amplified signal corresponds to a level in a range of less than 1 to 0.7 times the level of the stored reference signal. If the level is the same or 1.3 times the range is higher than the reference signal outputs a high value, and if less than 0.7 times or more than 1.3 times the level can be configured to output a warning signal.

The amplified signal is an amplified signal generated according to the intrinsic pressure drop of the epidural space generated when the needle for cervical anesthesia enters the epidural space. It arises from the inherent shape of the epidural space that is maintained, which is known as 12.75 to 26.15 mmHg (19.456.7 mmHg).

Therefore, the epi check point of the present invention is a principle that generates a signal by detecting the inherent pressure of the epidural space described above 19.456.7 mmHg when the needle for cervical anesthesia enters the epidural space, The epi check point of the present invention is not detected, which is not signaled when the needle is located in an empty space other than the spinal canal or epidural space as in the prior art, so that the needle was not located in the epidural space. It is possible to know the sound, which can prevent the failure of the procedure, which is the technical concept of detecting the epidural space by detecting the pressure in the prior art has not been confirmed, it is not implied unique technology of the present invention It is characteristic.

In addition, the epi check point of the present invention does not detect the intrinsic pressure of the epidural space when a general injection needle is used, and the intrinsic pressure must be used only by using an epidural needle or a spinal needle. It can be detected.

In the following description of the present invention, if it is determined that the detailed description of the related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

In the present invention, the device used for epidural anesthesia is referred to as an epidural confirmation device, and in particular, an epi check point.

Hereinafter, with reference to the accompanying drawings in detail, the epi-check point 100 is digitally operated is dural pressure sensor unit 1000, dural pressure differential amplifier 2000, dural pressure comparison unit 3000, dural pressure latch (4000), dural pressure display (5000), power supply (6000), switch (7000), dural pressure detection housing (8000), connection fixing (9000) and fixed support (200) and needle for cervical anesthesia It is a structure including 300.

The fixed support portion 200 is inserted into a cylindrical outer surface of the connection fixing portion 9000 by a forcible method so that it is installed in a press-fit method and detachable configuration separated by a mandatory method by manpower.

The fixed support part 200 is made of a polycarbonate material and the connection fixing portion 9000 is pressed into a cylindrical connection hole is formed in the portion is connected, the external shape of the connection hole is formed as a rectangular cylindrical shape as a whole. On the other hand, the outer surface of the rectangular cylindrical shape is formed in a series of linear protrusions and grooves in a continuous sequence to prevent slipping, the handle portion protruding in both directions along a straight line is formed on the end portion formed with a plurality of protrusions and grooves forced manner It is the structure which facilitates putting on and taking off. In addition, a needle insertion hole for cervical anesthesia is formed in the end surface formed with a handle protruding in both directions.

Cervical anesthesia needle 300 is a bar-shaped scale that can be easily distinguished on the outer surface, the needle is inserted directly into the epidural space of the human body, may be referred to as a puncture needle or catheter and the drug inside It is a tubular shape in which flowing holes are continuously formed, and examples thereof include epiunal needles and spinal needles.

On the other hand, the dural pressure sensor unit 1000 directly inputs the corresponding bio-pressure signal generated from the end of the injection needle or cervical anesthesia needle 300 from the muscle or yellow ligament and epidural space of the human body and digitally. ) As the signal is detected by the electrical insulation state by the processing method, the corresponding pressure is measured.

Here, the nervous system of the human body is affected by weak electrical signals, so it is very important to maintain electrical insulation.

The dural pressure sensor unit 1000 digitally detects the pressure generated from the muscles of the human body and the epidural space, measures the electrical insulation state with the human body, and converts it into a level signal by an electrical signal.

That is, since the epi check point 100 is a device or equipment that directly contacts the body or the human body, the signal output from the dural pressure sensor unit 1000 is converted into an optical signal instead of an electrical signal so as not to directly affect the human body. It can be output, and the receiving side has a corresponding configuration, so it can receive an optical signal and convert it into an electrical signal, and the electrical signal is processed digitally. The technique of the method is applied and will not be repeated. Further, digital signal processing is well known to those skilled in the art of electronic circuitry and will not be described in detail.

In the dural pressure sensor unit 1000, the end of the cervical anesthesia needle 300 receives 19.456.7 mmHg, which is a pressure generated from the muscles of the human body and an intrinsic pressure generated from the epidural space, and detects the corresponding pressure digitally. In general, the level of the signal is very weak.

The dural pressure differential amplifier 2000 amplifies the weak level of the signal that the dural pressure sensor unit 1000 detects and outputs digitally and amplifies it at a predetermined ratio. The amplification is amplified by a digital signal processing method.

The amplification ratio may be adjusted or selected by an external corresponding control signal, and is preferably amplified to any one level selected from a range of 10 to 30 multiples. In addition, it is very natural that a separate adjusting device or control device may be configured to adjust the amplification ratio, and a wireless circuit of a Wi-Fi type may be provided to control or control wirelessly.

The dural pressure differential amplifier 2000 outputs the digitally controlled amplification ratio and the amplified signal, respectively.

The dural pressure comparator 3000 inputs an amplified signal and an amplification ratio from the dural pressure differential amplification amplifier 2000, and digitally compares the reference signal stored in a state corresponding to the amplification ratio. Determine and output the value.

That is, the dural pressure comparison unit 3000 amplifies and outputs a corresponding signal meaning that the input signal is stored and is a value smaller than the reference signal when the input signal is stored and has a low level in the range of less than 1 to 0.7 times compared with the corresponding reference signal. If the level is equal to the level of the reference signal or 1.3 times the level, the signal is output higher than the reference signal.

The dural pressure comparison unit 3000 may output a warning signal when the amplified and input signal is stored and is lower than 0.7 times or higher than 1.3 times as compared with the corresponding reference signal. If it is confirmed that a signal of a level lower than 0.7 times or higher than 1.3 times is detected, the end portion of the cervical anesthesia needle 300 may be inserted into a part other than the muscle or epidural space. Control to output a signal. That is, there is an advantage of eliminating the possibility of a medical accident.

This value of 0.7 times or 1.3 times is generally the value of the level detected in other parts of the body, not in the muscle or epidural space, and can be adjusted because it can be expressed at different levels if the conditions of the body differ from person to person. As described above, the intrinsic pressure difference between muscle and epidural space is known to be in the range of 19.456.7 mmHg.

The epi checkpoint of the invention preferably detects 19.456.7 mmHg, the pressure difference between the muscle and epidural space, most preferably 19.456.7 mmHg.

On the other hand, the dural pressure comparison unit 3000 compares the pattern of the pressure change from the cervical anesthesia needle 300 is inserted into the human body by comparing the stored reference pressure change pattern with the digital signal processing method of the needle for cervical anesthesia 300. It may be possible to know whether the tip is located in the epidural space.

That is, it is very natural that the dural pressure comparison unit 3000 is configured by a digital program and data storage device, and can be applied in various ways. Such programs and data may be input or updated by wire or wirelessly. .

The dural pressure latch unit 4000 is a configuration in which a signal output from the dural pressure comparison unit 3000 is input, stored, and digitally controlled and processed, and may be configured as an R-S latch.

The dural pressure display part 5000 emits any one color selected from red and green according to the signal output from the dural pressure latch part 4000, and is formed of one selected from an LED element or an LCD element. You can also use the buzzer to sound.

On the other hand, the dural pressure display unit 5000 may further include a configuration for outputting a digital audio signal in the light signal, a high or low level signal, for example, any one signal selected from the red and green signal is continuous The warning signal may be caused to emit light, and the warning signal may cause the signal of the corresponding color to emit light repeatedly blinking, and may be digitally controlled and processed.

That is, when the detected pressure is much lower than the reference level, the red signal may be continuously emitted. When the detected pressure is much higher than the reference level, the green signal may be continuously emitted. Alternatively, it may be controlled to be operated in reverse or to be operated in various combinations.

The power supply unit 6000 is configured to output a direct current (DC) voltage of 3 volts, the dural pressure sensor unit 1000, the dural pressure differential amplifier 2000, the dural pressure comparison unit 3000, the dural pressure latch unit 4000 And the dural pressure display portion 5000, respectively, to supply the operating power. The operation power supplied as described above is provided by digital pulse width modulation (PWM), so it is easy to control power, and thus, there is an advantage of reducing overall power consumption.

The dural pressure sensor unit 1000, the dural pressure differential amplification unit 2000, the dural pressure comparison unit 3000, the dural pressure latch unit 4000, and the dural pressure display unit 5000 may be configured in one printed circuit board (PCB). The printed circuit board 110 may be configured such that the size of the width * length * height does not exceed 20 millimeters (mm), respectively. Therefore, it is possible to manufacture small and light weight.

The switch unit 7000 is connected to the power supply unit 6000 so that the operating power is the dural pressure sensor unit 1000, the dural pressure differential amplifier 2000, the dural pressure comparison unit 3000, the dural pressure latch unit 4000, and the dura mater. On / off control to be supplied or cut off in the form of a digital pulse (pulse) to the pressure display portion 5000, respectively, and made of any one selected from mechanical or electronic configuration.

It is preferable that the dural pressure display unit 5000, the power supply unit 6000, and the switch unit 7000 are installed and fixed at respective positions inside and outside, respectively, and have a circular box shape as a whole.

The connection fixing part 9000 is formed to protrude in a cylindrical shape on a central portion of one side of the dura mater pressure detecting housing 8000, and a through hole connected to the dural pressure sensor unit 1000 is formed at the center thereof.

That is, the connection fixing unit 9000 is configured to input the bio-pressure signal generated from the muscle and epidural space of the human body by the end portion of the needle for cervical anesthesia 300 and transmit it to the dural pressure sensor unit 1000. The cylindrical outer surface forms a tapered structure having a cross section of 1 slope or less in 100 minutes so that the epi check point of the present invention and the needle for cervical anesthesia are tightly coupled in a vacuum, or on the outer circumference of the connection fixing part 9000. It is preferable to form a spiral coupling part 400 so as to be closely coupled by rotating the needle for cervical anesthesia.

The connection fixing part 9000 of the epi check point of the present invention can be used only by connecting the needle 300 for cervical anesthesia by the fixed support 200, the medical needle used in general In this case, the pressure difference between the above-described muscle and epidural space, 19.456.7 mmHg, cannot be detected and thus cannot play a role.

In addition, in one embodiment of the present invention is provided with a spiral coupling portion 400 is formed on the outer circumference of the connection fixing portion and the cervical anesthesia needle in order to couple the connecting fixing portion and the cervical anesthesia needle by rotating the needle for anesthesia The epi check point of the invention and the needle for cervical anesthesia may also be strongly fixed, which is illustrated in FIG. 8.
