Abstract

A patient interface system integral with a critical care bed for allowing the acquisition, analysis, display, and conveyance of patient-related data from a variety of transducers. The system is adapted to recognize and interpret each type of signal being received, despite the type and/or make of the particular transducers. The system is also adapted to simultaneously display data traces and representative readings from a variety of transducers simultaneously on a single screen detachably mounted to the bed. The display screen is pivotally mounted for ease of use and may be detached from the bed together with the main processor when the corresponding features are not desired. The bed is adapted with electronic connection sockets along each side of the patient surface to present convenient connections for patient transducer leads. The system has resident memory for storing data to enable trend analysis or downloading for patient data records. Bedside medical devices can either be connected to the device by cable connections or by use of wireless connections and is capable of controlling various medical devices related to the bed or patient, potentially including patient turn actuators, scales, inflation devices and others.

Claims

1. A patient interface system comprising:

a critical care bed for supporting a patient, said critical care bed comprising a universal port for operatively receiving any one of a plurality grouping of conventional transducer leads, each member of said plurality grouping being adapted to cooperate with a conventional transducer to provide a signal related to a sensed physiological characteristic of the patient;

a processor linked in communication with said universal port, said processor being adapted (a) to receive a signal from said port, (b) to process the received signal to distinguish an identifiable component of the received signal, (c) to correlate such identifiable component with an identifying profile, and (d) to process the received signal based on data related to the identifying profile.

2. The patient interface system of claim 1, further comprising;

a display system for displaying the representation of signals processed by said processor relative to time, said display system being operatively linked with said processor, wherein said processor is adapted to interpret and display the processed signals utilizing said display system.

3. The patient interface system of claim 2, wherein said display system is pivotally mounted to said bed.

4. The patient interface system of claim 2, wherein said display system is detachably mountable on said bed and is pivotable relative to said bed when so mounted.

5. The patient interface system of claim 4, further comprising a detachable cartridge including said processor and said display system, wherein:

said processor is a slim-line processor;

said display system includes a flat display screen; and

said cartridge is adapted such that, when the cartridge is connected to the said bed, the display screen is pivotable about a horizontal axis relative to said bed for enabling viewing of said screen by a patient caregiver.

6. The patient interface system of claim 1, wherein:

said bed includes an elongated patient supporting surface having opposite lateral sides; and

said universal port is positioned, along with a plurality of additional ports, along opposite sides of said patient surface.

7. A patient interface system comprising:

a critical care bed for supporting a patient;

an electronic connection port adapted for operatively engaging a blood-oxygen transducer connected to the patient, to receive a signal from the transducer, said received signal being related to a blood-oxygen level of the patient;

a display screen;

a processor for processing said received signal, said processor being electronically connected to said port and to said display screen, said processor being adapted to interpret and display the patient'"'"'s blood-oxygen levels based on said received signal and to correlate and to simultaneously display the patient'"'"'s turn angle relative to the horizontal, thereby allowing correlation between the patient'"'"'s blood-oxygen levels and the patient'"'"'s turn angle.

8. The patient interface system of claim 7, further comprising;

a universal port; and

said processor being adapted to interpret signal received through said universal port to (a) sense a plurality of signals received at said port, (b) and to process and filter such signals to distinguish identifiable signals amongst such plurality of signals, (c) to correlate such identifiable signals with identifying profiles and (d) to process such plurality of signals based on data related to a particular profile.

9. The patient interface system of claim 7 wherein said processor is further adapted to control a patient turning device in response to said signal.
