Definitions

  • the present invention relates to medical devices and, more particularly, to specialized patient supports interrelated with medical data acquisition devices for optimally monitoring, processing, storing, displaying and utilizing patient data, both in the vicinity of the patient support and remotely thereto.
  • Patient data is often life-critical, especially in trauma and intensive care settings. It provides caregivers with objective information about the patient's condition. By comparing simultaneous data relating to a variety of strategic physiological parameters, caregivers can not only monitor and diagnose the patient's condition, but they can also evaluate the efficacy (and hence, value) of the patient's treatment.
  • a modern critical care room may also utilize a bedside computer terminal for patient charting.
  • the caregiver brings up the patient's chart electronically to determine what procedures have been prescribed and updates it as appropriate.
  • the overall result is a complex network of wires, transducers, displays, bulky cabinets and device carts surrounding the critical care patient.
  • a caregiver then has the task of watching and mentally correlating each of the various displays with the patient to make decisions as to patient treatment. For instance, if a patient's blood pressure is down, the patient may need to be positioned in the Trendelenburg position, or if Sa0 2 levels are low, automatic ventilation or kinetic therapy may be prescribed.
  • the long-recognized need in the critical care setting is to simultaneously correlate as much patient data with as many effective therapies as may be necessary to maintain and/or improve the patient's condition. The need to occasionally transport a patient from one room to another further complicates matters. When transporting, each of the numerous pieces of wheeled equipment must simultaneously be rolled to the new location.
  • the particular applications range from basic lead connections, to pressure relieving mattresses, to lateral rotation beds.
  • the present invention generally comprises a critical care bed for supporting a patient wherein the bed serves as the information conduit between one or more transducers and their respective monitors and/or other data recording devices either directly or through a provided telemetry interface.
  • the bed itself includes a processor for processing signals from the transducers.
  • the transducers function conventionally, providing analog signals corresponding to sensed physiological characteristics of the patient.
  • Conventional transducer leads and lead connectors are virtually inherent.
  • the processor may also be conventional, although it is adapted for simplifying signal analysis and monitor recognition.
  • the bed is provided with a universal port for receiving any one of a number of conventional lead connectors and linking the same to the processor.
  • a plurality of linked alternative ports could be structured as another alternative.
  • the processor is adapted to sense the signals received at the universal port (or from any one of the series of ports) and to "recognize" the source of such signals. With most digital signals, the data stream can be matched to the corresponding medical device. Source recognition for all analog signals and certain digital signals, on the other hand, will typically involve signal analysis of the signal on each pin of a transducer and then pin-mapping all the signals together.
  • the signal analysis identifies the type of signal being conveyed on a particular pin - i.e., whether the signal is a steady, reference voltage or a fluctuating one and, if fluctuating, whether it is fluctuating in a manner characteristic of any particular type of physiologic or environmental signal.
  • Pin-mapping then correlates the signals of the various pins of a multi-pin transducer lead to distinguish an identifying profile and identify the corresponding signal source from the known bank of possibilities.
  • the system as a whole can then identify the make of multi-pin transducer signals and process the signals based on pre-defined data related to the particular signal source (i.e., the particular type and/or make of patient transducer).
  • the processed data may then be displayed on a universal monitor, recorded by a standard charting device or telemetered to a remote location.
  • a plurality of such universal ports may be positioned along opposite sides and/or at opposite ends of the patient support surface.
  • Another aspect of the present invention provides for integrating an Sa0 2 monitoring system with a display system that enables caregiver to correlate Sa0 2 with lateral rotation data.
  • Such a system may also utilize a universal port as referenced previously, and may be logistically linked with the critical care bed controls to modify the therapy protocol in response to the current and/or historical Sa0 2 levels.
  • Eventual concepts of incorporating self regulating systems of patient care or physician approved suggestions of a smart system could be included. Axial routing of data lines from the transducers to the detachable processor and thence to the respective external monitors not only renders a convenient data conduit, but also helps eliminate potential for taught-line problems.

  • Bed assembly 11 is essentially a Roto Rest Delta bed presently commercialized by KCI Therapeutic Services, Inc. of San Antonio, Texas, with certain adaptations.
  • the Roto Rest Delta bed of bed assembly 11 is adapted with interface cartridge 50 and a variety of transducer ports 32a-32j, monitor ports 21a-21e, printer port 20, and communication ports 22a and 22b, as well as numerous related electrical connections (such as line 33f and many others that are not shown) as referenced generally in connection with Figure 1.

  • bed 11 may be embodied in the Triadyne type low air loss bed as also presently commercialized by KCI Therapeutic Services, Inc. of San Antonio, Texas.
  • Interface cartridge 50 is a detachable cartridge that serves in part to facilitate the interface between transducers such as transducers 30a-30g and 34a-34c and the user.
  • interface cartridge 50 facilitates such interface by providing a data storage and/or display device for the benefit and convenience of patient caregivers.
  • interface cartridge 50 uses received data to modify the operation of inboard operative devices 13a and 13b and/or external operative devices 40a and 40b.
  • Bed assembly 11 as a whole, provides a convenient conduit for conveying signals received from transducers 30a-30e to remote monitors (not shown) that may be linked to ports 21a-21e.
  • Ports 21a-21e may be adapted as desired, but it is presently preferred that they be of such construction that would facilitate connection of leads like leads 31a-31e, respectively.
  • bed assembly 11 in concept can be simply interjected between transducers 30a-30e and the monitors that are traditionally used with such transducers, all without interrupting or altering the signal between transducers 30a-30e and their corresponding monitors.
  • FIG 1A when interface cartridge 50 is detached from bed assembly 11, signals carried by lines 33a-33e are still conveyed to ports 21a-21e.
  • Figure 1A a more accurate representation of the relationship between lines 33a-33e, interface cartridge 50, and lines 24a- 24e is shown in Figure 1A.
  • patient interface system 10 is described with specific numbers and identities of multiple components. For instance, there are seven specific external transducers, three internal transducers, two in-board operative devices, and two external operative devices. Some of the multiple components will be described with specific detail while others (such as the external operative devices 40a-40b) may be left generic. For purposes of this description, both the illustration and description of many of these components is also greatly simplified.
  • Blood pressure transducer 30b may be described only as a transducer with an electronic signal related to the blood pressure of patient 200; whereas one of ordinary skill in the art would recognize that a typical non-invasive blood pressure transducer is inoperative without an inflation cuff and related components and that the signal from such a transducer would actually be either a comprehensive digital signal or multiple analog signals which could be interpreted in combination to determine the patient's blood pressure.
  • This description will, hence, be best understood by those of ordinary skill in the art who, with reference to presently available technology, would recognize and understand such simplifications.
  • the selection and details related to such multiple components generally should not be read as limitations on the scope of the present invention, unless such details are required by the claims appended hereto which define the scope of this invention, once properly construed.
  • Transducer 30a is an Sa0 2 transducer for sensing the blood-oxygen saturation levels of the patient.
  • Transducer 30b is a blood pressure transducer for sensing the blood pressure of the patient.
  • Transducer 30c is a heart rate transducer for sensing the heart rate, or pulse, of the patient.
  • Transducer 30d is an ECG transducer for sensing an electrocardiogram signal of the patient.
  • Transducer 30e is a core temperature transducer for sensing the core temperature of the patient.
  • Transducer 3 Of and 30g can be considered strictly as transducers but are actually transducer systems that include both an independent processor (and other components) together with a transducer.
  • Transducer 3 Of, for instance, is actually a patient ventilator that includes one or more pulmonary monitor transducers 44 linked to processor 45 by lead 46.
  • Processor 45 processes the signal from transducer 44 to produce a more comprehensive signal representative of the patient's breathing activity. Processor 45 then transmits that more comprehensive signal through lead 3 If.
  • Transducer 30g is a drug or IV infusion pump unit that likewise includes a transducer 47 and processor 48 work to monitor the volume of fluid being infused to a patient and to transmit a corresponding signal through line 3 lg.
  • transducers 30a-g are conventional, selected from those that are well known in the industry, through a variety of manufacturers. Though well known, many such transducers are commonly dedicated to an independent monitor but are typically detachable from said monitors, leaving the transducer 30 itself and its corresponding lead 31.
  • the leads 31, operatively connected between the corresponding transducer 30 and connection port 32, are simply electrical leads of appropriate construction - that is, appropriate for communicating the electrical signals from the transducer 30 to a processor that is adapted to interpret such signal and, hence, monitor the intended physiological or environmental condition sensed by transducer 30.
  • each such lead 31 is provided with a conventional lead connector 31 ' at its distal and (i.e., the end of lead 31 which connects to the corresponding connection port 32).
  • a conventional lead connector 31 ' at its distal and (i.e., the end of lead 31 which connects to the corresponding connection port 32).
  • Bed 11 is provided with a plurality of transducer connection ports, or sockets, 32a-32j for receiving individual leads 31a-31g of transducers 30a-30g and enabling electronic communication between such transducers 30a-g and interface cartridge 50 as well as remote monitor ports 21a-21e.
  • ports 32a-32j are unique to particular types of lead connectors, despite the fact that they are all represented the same in Figure 1.
  • transducer port 32b has a construction adapted to operatively receive a conventional blood pressure transducer lead 31b, which has a certain number of pins arranged in a certain geometry of a certain size.
  • each of ports 32a-e are of the same construction, geometry, etc., as the ports already commercially available which are adapted to receive transducer leads 31a-31e. This works best when all of the transducer leads to be connected to a particular port are the same.
  • a leading blood pressure transducer manufacturer for instance, is Colin Medical of San Antonio, Texas, and port 32b is adapted for operatively receiving the conventional leads provided with their blood pressure transducers. Hypothetically, it may also be that all competitors for a given type of transducer use the same transducer lead, in which case selection of the construction of port 32 will be an easy decision. In another case, there may be several popular alternative transducers of the same general type, and each separate manufacturer may have its own unique type of transducer lead. System 10 addresses such a situation by providing a universal port, which is a transducer port (or series of ports) that will interface with a variety of different transducer leads.
  • one representation of the universal port concept relates to the series of sockets 32a, 32i and 32j for receiving the Sa0 2 transducer lead 31a.
  • the Sa0 2 monitoring market is representative of a market where the transducer leads for Sa0 2 transducers made by different manufacturers are likewise different and unique.
  • such series of ports 32a, 32i, and 32j are oriented immediately adjacent one another in a location proximate to the hand 201 of patient 200, where many Sa0 2 leads are adapted to be connected.
  • the socket 32a is adapted to receive the transducer lead made by one manufacturer, such as a Nellcor lead; the socket 32i is adapted to receive the lead made by another manufacturer; and the socket 32j is adapted to receive the lead manufactured by yet another manufacturer or category of manufacturers.
  • transducer port 32e Another manner of providing a universal port to address the stated need is represented in connection with transducer port 32e.
  • a single temperature transducer port 32e is provided for multiple makes of temperature transducer leads 31e.
  • the port 32e is particularly adapted to receive the most popular, or most preferred, type of temperature transducer lead, and adapter 43 is utilized to enable connection to the transducer lead of a less popular, or less preferred, type of transducer lead.
  • a plurality of adapters 43 may be made available if it is desired to have more than two basic types of transducer leads 3 le connectable at the same port 32e.
  • Transducer ports 32f-32h are universal in the sense that they are each of the standardized RS-232 format.
  • any transducer (or transducer system) using a transducer lead of the RS-232 format can be connected to any of ports 32f-32h.
  • eight connection ports 32a-32j are shown (considering sockets 32a, 32i and 32j are a single port), only seven transducers 30a-g are illustrated. An additional transducer may be connected to the remaining connection port 32h, as desired.
  • Electronic communication lines 33a-33k are conventional lines that electronically link transducer ports 32a-32j to interface cartridge 50 so that cartridge 50 receives any signals that are received at ports 32a-32j.
  • Such construction is generally straight forward - if transducer port 32b is a 10-pin port, then electrical connection 33b is an electrical connection capable of transmitting at least 10 parallel signals, each correlated to a separate pin of transducer port 32b.
  • Conventional ribbon cables and/or conventional coaxial cables are preferred for each of lines 33a-33h, and others. The only particular complication relates to the series of sockets 32a, 32i and 32j, wherein corresponding electrical leads 33k, 33i and 33j merge into a single electrical lead 33 a.
  • any conventional means of merging such lines is suitable for this purpose; however, it should be noted that one of ports 32a, 32i and 32j may have a different number of pins than the others. In such a case, the lines 33k, 33i and 33j can still each have the same number of conductors, even though some of such conductors may not be required for each of the different transducer sockets 32a, 32i and 32 j. For example, if socket 32 a has ten pins, socket 32i has eight pins, and socket 32j has four pins, then a ten conductor line will be used for each of lines 33a and 33i-k, with some conductors not being used for sockets 32i and 32j.
  • transducers 34a, 34b and 34c are also electronically linked with interface cartridge 50.
  • Such link in the preferred embodiment, is directed through the central processing unit 36 of bed 11. More particularly, transducers 34a, 34b and 34c are linked to bed processor 36 by transducer leads 35a, 35b and 35c respectively.
  • Bed processor 36 then processes the signals received through transducer leads 35a, 35b and 35c in the same manner as though interface cartridge 50 were not a part of bed assembly 11.
  • Bed processor 36 for reference, is the control unit in the presently commercialized version of the Roto Rest Delta bed, and is mounted within the enclosure of control panel 80. Having processed signals received from leads 35a, 35b and 35c, processor 36 then transmits a representative signal through interprocessor link 37 to interface cartridge 50.
  • Releasable connections such as at ports 32 are not shown in lines 35a-35c, both for simplicity and as they are not required, although they may be utilized for convenience in servicing bed 11.

Abstract

L'invention concerne un système d'interface avec les patients intégré à un lit (11) pour soins aux patients en phase critique, qui permet l'acquisition, l'analyse, l'affichage et la transmission de données relatives aux patients, via une pluralité de transducteurs. Le système est conçu pour reconnaître et interpréter chaque type de signal reçu, indépendamment du type et/ou de la marque des différents transducteurs. Le système est également conçu pour afficher simultanément la trace des données et les indications représentatives émanant d'une série de transducteurs, sur un seul écran monté amovible sur le lit (11). L'écran pivote par souci de commodité, et l'écran et le processeur principal sont démontables du lit (11) lorsque les fonctions correspondantes ne sont pas requises. Le lit (11) est doté de douilles de connexion le long de chaque côté de sa surface, ce qui permet de raccorder aisément les douilles aux conducteurs des transducteurs prévus pour les patients. Le système comporte une mémoire résidente qui permet d'enregistrer des données pour l'analyse des tendances ou de télécharger des fichiers de données relatives aux patients. Il est possible d'effectuer un raccordement câblé (51) ou hertzien (100, 101) entre le système et des dispositifs médicaux placés au chevet du lit, moyennant quoi le système est capable de commander le fonctionnement des divers dispositifs utilisés en liaison avec le lit ou le patient, à savoir par exemple : dispositif lève-malade, balance, dispositif gonflable et autres.
