Abstract

A patient support apparatus includes one or more readers and/or sensing devices to receive data that can be use to verify the identity of persons or objects, such as patients, caregivers, and medications. The sensing devices may include, for example, a biometric sensor, a physiological sensor, a bar code reader, a camera, a microphone, or a combination thereof. The patient support apparatus may use identity verification information obtained from these devices for a number of different purposes, including, for example, managing the delivery of therapy, medication, or treatment to a patient associated with the patient support apparatus.

Claims

1. A patient support apparatus embodied as a hospital bed comprising:

a support frame configured to support a patient in a plurality of positions including a horizontal position;

an inflatable patient-support surface supported by the support frame;

a siderail coupled to the support frame;

a first sensing device supported by the siderail;

a second sensing device supported by the siderail, the second sensing device being a different type of sensing device than the first sensing device;

bed function controls coupled to the siderail, the bed function controls being useable to raise and lower the support frame and to adjust inflation parameters of the inflatable patient-support surface; and

a control module in communication with the first sensing device and the second sensing device to verify the identity of a person based on first identity information received by the first sensing device and second identity information received by the second sensing device, the first identity information being different than the second identity information, wherein the control module is configured to analyze vital signs sensing data produced by at least the first sensing device to (i) determine a current health state of a patient supported by the support frame and (ii) verify the identity of the patient, wherein the control module initiates at least one electronically-controllable function of the patient support apparatus in response to the vital signs sensing data.

2. The patient support apparatus of claim 1, wherein the control module is in communication with the first sensing device to verify the identity of a medication based on medication identity information received by the first sensing device.

3. The patient support apparatus of claim 2, comprising a display supported by the siderail, wherein the display is in communication with the control module to display content relating to a medication whose identity has been verified by the control module and to display content relating to a person whose identity has been verified by the control module.

4. The patient support apparatus of claim 3, wherein the content relating to the medication comprises one or more of dosing information relating to the medication and a digital image of the medication.

5. The patient support apparatus of claim 3, wherein the content relating to the person comprises one or more of prescription information relating to the person and a digital image of the person.

6. The patient support apparatus of claim 2, wherein the control module is configured to send data relating to a medication verified by the control module to an electronic medical records system.

7. The patient support apparatus of claim 2, wherein the control module is configured to send an alert to a healthcare communication system if the control module is unable to verify the identity of the medication.

8. The patient support apparatus of claim 1, wherein the first sensing device comprises a non-biometric sensor and the second sensing device comprises a biometric sensor, and the control module is configured to verify the identity of the person based on non-biometric data received from the first sensing device and biometric data received from the second sensing device.

9. The patient support apparatus of claim 8, wherein the first sensing device comprises a barcode reader, the second sensing device comprises a fingerprint reader, and the control module is configured to verify the identity of the person based on fingerprint data received from the fingerprint reader and barcode data received from the barcode reader.

10. The patient support apparatus of claim 1, wherein the first sensing device comprises a radio-frequency identification (RFID) sensor, the second device comprises one of a camera and a microphone, and the control module is configured to verify the identity of the person based on RFID data received from the RFID sensor and one of facial recognition data received from the camera, barcode data received from the camera, and voice data received from the microphone.

11. The patient support apparatus of claim 1, wherein the control module is configured to send data relating to a person verified by the control module to an electronic medical records system.

12. The patient support apparatus of claim 1, wherein the control module is removably coupled to the siderail.

13. The patient support apparatus of claim 1, wherein the control module is configured to send an alert to a healthcare communication system if the control module is unable to verify the identity of the person.

14. A patient support apparatus embodied as a hospital bed comprising:

a support frame configured to support a patient in a plurality of positions including a horizontal position;

a siderail coupled to the support frame;

an inflatable patient-support surface supported by the support frame;

bed function controls coupled to the siderail, the bed function controls being useable to raise and lower the support frame and to adjust inflation parameters of the inflatable patient-support surface;

a control module supported by the support frame or the siderail;

a pulse oximeter module supported by the siderail, the pulse oximeter module comprising;

a communication port to connect a pulse oximetry sensor apparatus to the pulse oximeter module; and

a display to display pulse oximetry data obtained by the pulse oximetry sensor apparatus from a patient positioned on the patient support apparatus, wherein the control module is configured to analyze vital signs sensing data produced by at least the pulse oximeter module to (i) determine a current health state of a patient supported by the support frame and (ii) verify the identity of the patient, wherein the control module initiates at least one electronically-controllable function of the patient support apparatus in response to the vital signs sensing data.

15. The patient support apparatus of claim 14, wherein the pulse oximeter module is integrated with the siderail.

16. The patient support apparatus of claim 14, wherein the pulse oximeter module is removably coupled to the siderail.

17. The patient support apparatus of claim 14, wherein the communication port and the display are positioned on different sides of the pulse oximeter module.

18. The patient support apparatus of claim 17, wherein the communication port and the display are positioned on opposite sides of the pulse oximeter module so that when the pulse oximeter module is installed in the siderail, the display faces a caregiver positioned adjacent the patient support apparatus and the communication port faces a person positioned on the patient support apparatus.

19. The patient support apparatus of claim 14, wherein the display displays pulse oximetry data comprising both graphical and textual data.

20. The patient support apparatus of claim 14, comprising a control module to communicate the pulse oximetry data from the patient support apparatus to an electronic medical records system.

21. The patient support apparatus of claim 14, comprising a control module to determine based on the pulse oximetry data whether a person is positioned on the patient support apparatus.

22. The patient support apparatus of claim 14, wherein the control module is configured to initiate, modify, or terminate an electronically-controlled function of the patient support apparatus, an alert, or an alarm, in response to the pulse oximetry data.

23. The patient support apparatus of claim 14, wherein the control module is configured to verify the identity of the patient based on the pulse oximetry data and based on other data.
