description

The invention relates to a measurement data converter for use in a patient monitoring system with wireless data transmission of patient-related, detected by means of transducers data between the Meßdatenumsetzer and a receiving device.

Hospitals and other health care facilities often require the monitoring of patient-related physiological and physical data in a continuous manner. The monitoring is especially during the transport of a patient between different treatment or

Investigation sites desired. Come for this

Patient monitoring systems, in particular those with wireless data transmission, are used. In such systems, as far as possible close to the patient medical measurement signals are converted by means of transducers into electrical signals, possibly processed and fed (via a cable connection or wirelessly, for example via a radio link) to a transmitting unit. The assemblies involved are movable with the patient, for example, at the operating room bed,

Intensive bed or transport bedNursing bed arranged. By means of the transmitting unit, the signals are transmitted to one or more usually stationary arranged receiving devices, the

For example, associated with evaluation and / or display devices and which are monitored, for example, by medical personnel.

In EP 0 603 666 A2 is a pressure data monitor for a

Patient monitoring system of the type mentioned above described. Here are pressure transducers together with a

Data transmission device arranged on or in a housing.

Especially for use in hospitals to the

Patient-side parts of the patient monitoring system be portable and flexibly placeable. Especially if a lot of

Patient sensors and transducers used for monitoring can create confusing arrangements of devices and cables. This can increase the risk of unwanted interruptions of the contacts to the measuring devices or incorrect cable assignments to devices and further complicates and / or slows down the transport of the patient. In addition, through a variety of

Cable connections are confusing, which requires time-consuming connection changes or new installations when the patient is to be mobilized. Cabling problems can also be caused by kinking or tearing of cables, or by corrosion of cables or contact connections for the cables

be caused. This can lead to signal disturbances, interruptions and / or false positives, which may pose an increased risk to the health of the patient.

In addition, the usually high have problematic

Requirements for hygiene and the robustness of the devices against typical effects in the clinical environment are highlighted. In particular, the data acquisition transducers must be frequently manipulated during medical treatment, or between the use of the patient monitoring system for various patients for hygienic reasons to reduce the risk of infection

be replaced. During this handling, it may therefore be on the patient-side devices, and in particular in the field of

Instrument transformers, come to contamination, such as blood or medical substances.

The invention has for its object to provide a measurement data converter for a patient monitoring system, which a

Clear and hygienic arrangement of transducers in

Patient proximity allows, as well as easy handling and

Transportability supported.

This object is achieved by a measurement data converter according to claim 1. The measured data converter of the patient monitoring system accordingly comprises a transmission unit arranged in a housing for (wireless) data transmission and a carrier part for receiving Transducers. According to the invention, provision is made for a connection joint for the bendable and detachable mounting of the carrier part to the transmitter unit to be provided, and for the carrier part to hold holding means for releasably holding transducers and also signal conducting means for forwarding data between them

Has transducers and the transmitting unit. The support member may also power conducting means for powering the

Have transducer.

The transducers of the patient monitoring system can

be designed for example for the measurement of blood pressure, in particular invasive blood pressure, oxygen partial pressure, temperature, ECG signals or pulse. In particular for the measurement of invasive blood pressure or temperature, disposable articles are used in clinical operation, which can be used in the holding means and, for example, between the application of the

Patient monitoring system for different patients

can be replaced at a change of patient or longer period of use regularly.

In the operation of the patient monitoring system by means of

Sending unit of the data converter the patient-related

Transfer measurement data to a receiving device via a wireless communication link. Furthermore, it is conceivable that in

Measuring data converter, in particular in the transmitting unit, a gain, filtering of interfering signals, processing or

Digital-to-analog-to-digital conversion of the measured data takes place.

The connecting joint can be formed, for example, as a mechanical hinge with interlocking rigid sections or as a flexible supporting connection, for example, from a flexible plastic, between the transmitting unit and the carrier part.

In the holding means are used when using the Meßdatenumsetzers as needed transducers. The holding means act together with the signal line means such that the forwarding of

Measured data between mounted transducers and the transmitting unit is possible.

An essential advantageous aspect of the use of

Patient monitoring systems with wireless data transmission is that the measurement units for patient-related data can be transported with the patient. For example, in hospital use can so at

Laying between different treatment locations (operating room, intensive care unit, treatment room) a continuous

Patient monitoring will be enabled. When measured data converter according to the invention is housed in a housing

Transmitter unit compact and can be arranged near the patient, for example, the transportable hospital bed. Since the transducers are halterbar on a common carrier part, even with a variety of used transducers a clear

Arrangement. Complex cable runs and cable bundles between transducers and transmitter unit are eliminated, which avoids the risk of accidental tearing / buckling / breaking or confusion of cables or hanging on objects during transport.

Since the carrier part in turn can be arranged on the transmitting unit, and the overall structure of the Meßdatenumsetzers is kept compact in the assembled state. Even with a large number of transducers and a correspondingly sized carrier part, a compact state of the measuring data converter can be produced for transport by angling the carrier part over the connecting joint in relation to the transmitting unit. Overall, so by the

Measuring data converter according to the invention significantly improves the speed and safety of the transport of the patient-side device, which contributes significantly to the quality and safety of the treatment. The wireless, clear and bendable arrangement of the transducers on the transmitter unit by means of a support member thus support the benefits of a wireless patient monitoring system crucial.

As the carrier part for the transducer detachably connected to the transmitting unit

can be held, is the measurement data converter according to the invention very flexible. Thus, a simple adaptation of the device and its arrangement for different applications is possible. For this purpose, for example, depending on the needs of different transducers are used in the holding means and the transducers are easily replaced. The transmitting unit is advantageously largely universally applicable. Therefore, for example, to adapt the

Measuring data converter to different monitoring situations or to different patients the entire carrier part together with the

Transducer assembly to be replaced. Depending on

Space requirements or desired mobility of the device can be used differently sized support members with a different number of holding means for transducers. The measurement data converter is therefore easily flexible and individually customizable.

The described flexibility of the arrangement and the compact design also makes it possible to arrange the measurement data converter close to the patient, even if space is limited.

For example, for the measurement of invasive blood pressure, this has the advantage that the required fluid hoses from the transducer to the patient can be kept short. This allows the

Accuracy can be increased and the risk of unintentional tearing or breaking of the fluid hoses can be reduced, thereby avoiding unnecessary fluid volume in long fluid hoses. This is also advantageous for a low-noise

Measurement data transfer. In particular, disturbing resonance effects can be avoided.

In clinical operation occur on the data converter of a

Patient monitoring system often pollutes and

Impurities on. This is the case in particular in the field of transducers, since here during the medical treatment and the

Transports often manual manipulations and adjustments

must be made. For reasons of hygiene, therefore, frequent cleaning in the area of the transducers is required. By releasably arranging the support member for the transducer at the Transmitting unit cleaning can be considerably simplified by the carrier part is removed for cleaning. In particular, by replacing the entire support member when needed immediately

unpolluted carrier part can be provided. Furthermore, in contrast to the transmitting unit, the carrier parts may be designed such that no sensitive electronic components are included. This allows an uncomplicated and quick cleaning of soiled carrier parts. Furthermore, the operation of the

Data converter can be interrupted only briefly to a

Use unpolluted carrier part. In this respect, an almost continuous operation is possible and improves the monitoring safety of the patient.

The direct arrangement of the carrier part with the transducers on the

In addition to a spaced arrangement, the transmitting unit has the further advantage that electrical signal paths are kept short. Since high-frequency electromagnetic interference signals, such as those emitted by other medical devices, can be coupled in the conduction of the measured data by means of extended signal conductors, the arrangement according to the invention has a comparatively low susceptibility to interference.

For advantageous embodiment of the invention it is provided that on the transmitting unit, a holding device for releasably holding the

Measuring data converter is provided on an outer support device. In particular, the holding device is arranged on the housing of the transmitting unit. In this respect, by means of the holding device, the transmitting unit is supported directly and the carrier part indirectly via the connecting joint. As an external support, for example, comes

Patient bed, in particular a bed rail on a patient bed, an IV pole or a medical tripod into consideration. The holder by means of the releasable holding device allows the

according to the invention to arrange the data converter according to individual requirements close to the patient. The detachable holder allows easy and quick height adjustment of the Measuring data converter including transducers to the patient. This is particularly advantageous when using transducers for invasive blood pressure measurement, wherein the blood pressure is transmitted via fluid-filled pressure hoses from the patient to a transducer and the transducer to increase the accuracy of measurement is preferably arranged at the level of the patient's heart. If, for example, the position of the patient changes during transport, the height of the measuring data converter and thus the height of the measuring transducer can be changed quickly and easily by means of the releasable holding device.

A further embodiment results from the fact that the

Connection joint sendeeinheitsseitig or carrier part side is arranged. A carrier part-side arrangement of the joint allows easy replacement of the connecting joint in case of damage. The

Transmitter unit can be made comparatively compact and robust. The comparatively simple and cheap carrier part in this case contains all moving mechanical parts and can at

Damage to the connecting joint can be exchanged cost-effectively. Alternatively, the connecting joint can be both

sender unit side and carrier part side be arranged such that the joint function is provided only by the assembly for holding the support member to the transmitting unit.

To further embodiment of the invention, the support member is stepless or between different locking positions in discrete steps

bendable. The carrier part can, for example, between a

Operating position in which the holding means and / or the Erten held therein transducers are easily accessible, and a transport position in which a compact overall arrangement of carrier part and

Transmitting unit results, be adjustable. On the other hand, continuous steplessness allows the relative arrangement of carrier part and

Transmitter unit to suit the respective space requirements or visibility.

Advantageously, a locking means is provided such that the

Carrier part is detected in different locking positions. Especially In this case, the determination in a latching position is releasable again.

Preferably, the locking means comprises a

connecting-joint-side locking means, a carrier part-side

Gegenrastmittel, as well as an actuatable actuating means such that by actuation of the actuating means, the counter-locking means in engagement with the

Locking means can be brought or released. In particular, it is provided that with the adjusting means, the engagement of the counter-locking means in the locking means is releasable again. The detectability of the carrier part in different

Latching positions is advantageous, for example, to allow the operation of an evasion of the support member from the spatial conditions or visibility adjusted position.

Preferably, it is provided that a lockable securing means is provided such that a release of the holder of the support member is prevented at the transmitting unit by locking the securing means. The securing means may include, for example, a quick and easy to use latch button or a bayonet lock or a lockable and re-releasable connector. The securing means can be arranged both on the sender unit side and on the carrier part side, in particular in the region of the connecting joint. If the transmitting unit is held by means of a holding device on an outer supporting device as described above, can be avoided by the lockable securing means falling of the indirectly supported Erten support member.

A particularly preferred embodiment of the measured data converter

results from the fact that the housing of the transmitting unit is formed substantially cuboid and the connecting joint such

is arranged, that the carrier part on one side of the housing halterbar and along this side is angled. Preferably, the support member is also substantially cuboid and dimensioned according to the dimensions of the housing of the transmitting unit.

An advantageous embodiment also results from the fact that the connecting joint a releasable electrical contact or

Connector for forwarding the data from the transducers to the transmitting unit includes. This can be achieved in that Connecting the carrier part with the transmitting unit simultaneously

Connection is provided for forwarding the data from the transducers to the transmitting unit. Furthermore, the electrical contact or plug connection between the carrier part and the housing of the transmitting unit makes it possible to supply the power to the mounted measuring transducers. Also conceivable is a separate power supply to the transducers by means of a mobile voltage source (battery) arranged on or in the carrier part or by means of a power supply produced by a plug connection via a power supply. For supplying power to the transducers may also be provided a separate power supply, which is docked to the support member.

Advantageously, the holding means for the transducers are such

in that a connection to a signal-conducting means of the carrier part is produced by holding a measuring transducer in a holding means. This can be used for the operation of the measuring data converter

required contact with a signal conducting means and / or the

Supply voltage of the transducers are essentially provided by the insertion of a transducer into a holding means. Another step, such as connecting cables over

Plug connections, can be saved.

An advantageous embodiment also results from the fact that the holding means for the transducer freely accessible electrical

Have contact surfaces on the surface of the support member such that by holding a transducer an electrical connection to a signal conducting means and / or to power the transducer of the support member is made. It is conceivable, for example, that the holding means have contact pads, which at the onset of a

Instrument transducer cooperate in a holding means with associated transducer side contact surfaces. Such contact surfaces avoid on the one hand recesses and gaps, as for example in

Plug sockets occur and in which impurities and dirt accumulate and can lead to corrosion. On the other hand, by the freely accessible arrangement on the surface simplifies the cleaning of the contacts.

It is particularly preferred if the holding means are dimensioned and adapted to the transducer so that a transducer by snapping, clipping or clipping, insertion or pushing or clamping or clamping with the holding means is halterbar. In addition, it is particularly advantageous if the holding means are designed for the releasable mounting of measuring transducers designed as disposable articles. In clinical use, this allows the quick and easy replacement of transducers, which are usually manufactured as mass-produced with standardized dimensions.

A particularly preferred embodiment is characterized in that the transmitting unit, the support member and the connecting joint are formed substantially liquid-tight. Furthermore, an advantageous embodiment results from the fact that the connecting joint is designed such that the carrier part is substantially liquid-tightly connected to the transmitting unit. As a result, a simple cleaning of the measuring data converter and / or its modules is made possible, whereby the risk of damaging sensitive components, for example the electronics of the transmitting unit, is largely avoided.

Accordingly, damage to these components by

Contamination with liquids largely prevented

fluid-related electrical short circuits or incorrect connections largely prevented.

A further advantageous embodiment of the invention results from the fact that the transmitting unit has at least one display means for functions of the patient monitoring system and / or for measurement data and / or at least one operating element for functions of the

Patient monitoring system provides. It is particularly advantageous if the housing of the transmitting unit and the carrier part are substantially cuboid and the display means and / or the operating element is arranged on a front side of the transmitting unit, wherein the carrier part is bendable between a first position in which the carrier part in Essentially in one plane Continuation of the front side extending beyond the housing and a second layer in which the support member extends substantially perpendicular to the front side.

It is particularly preferred if in this case the holding means are arranged on the support member such that in the first position, the transducers in the

Level of the front can be arranged.

As a result, in the first position during operation of the measuring data converter both the transducers and the display means and / or the

Operating element facing the user and easily accessible. To the

Support device 21 can be provided by an IV pole, by a tripod or by a part of a bed frame of a hospital bed, operation bed or transport bed.

In the figure 3, the support member 9 is shown detached. The support member 9 has four identically designed holding means 23 for releasable mounting of transducers, not shown (the transducers and their support are described below in Figure 4). In each of the holding means 23 four electrical contact surfaces 25 are provided, which are arranged freely accessible in the region of the surface of the support member 9. The contact surfaces 25 are formed such that upon insertion of a transducer into a holding means 23 of the transducer is contacted by the contact surfaces 25 electrically. Furthermore, stand the

Contact surfaces 25 with signal line means 27 of the support member 9 in such a way that electrical signals can be forwarded.

In addition, a voltage supply for the transducers is provided by the contacting.

The carrier part 9 further provides a part of an electrical connector 29, so that data from transducers can be forwarded via the contact surfaces 25 and the associated signal line 27 and the connector 29 to the transmitting unit 7, when the transmitting unit 7 and the carrier part. 9 are connected. Furthermore, the

Power supply of the transducer via the connector 29 by a not shown, sendereinheitseit power source provided.

In the carrier part 9 shown in Figure 3, the connecting joint 11 is arranged completely on the carrier part side. For holding the carrier part 9 to the transmitting unit 7, a connecting portion 31 by means of locking lugs 32 with an associated portion of the housing 8 of the transmitting unit 7 (not shown in Figure 3) connectable.

The embodiment shown in Figure 4 of an inventive Measuring data converter 40, which essentially the

Measuring data converter 3 corresponds, in turn, has a arranged in a housing 8 transmitting unit 7, with which a connecting part 11, a support member 9 is connected. Both the housing 8 of the transmitting unit 7, as well as the support member 9 are formed substantially cuboid.

The transmitting unit 7 has a front side 42, which is made available to a user for operating the measuring data converter 40 or

is turned. The carrier part 9 has four holding means 23, which are arranged side by side on an end face 41 of the carrier part 9. In the holding means 23 transducers 35 are clipped. The transducers 35 are designed here as transducers for invasive blood pressure. For operation, the transducers 35 are connected via fluid tubing, not shown, to a patient-side probe patient. The

Transducers 35 are usually designed as disposable articles, which are replaced for reasons of hygiene and contamination protection between the application in different patients or during prolonged monitoring of a patient. In this respect, mass-produced articles are used in particular for the transducers 35. For clipping the transducers 35 in the holding means 23, the transducers 35 on flexible locking tabs 36, which are latched into correspondingly formed, associated recesses 24 of the holding means 23.
