Abstract

A location detection system identifies the locations of medical devices such as patient support apparatuses and/or patient care devices within a medical facility. The devices communicate via a wired connection to one or more medical facility systems (e.g. nurse call system, computer network, etc.), and/or via a wireless connection to such systems. The location detection system automatically determines location information of the devices and communicates the location information so that the recipient of any outgoing alerts and/or other information sent from the devices is apprised of the location of the particular device sending the alert or other information. Caregivers are thereby able to respond to the correct location of an alert, and software systems such as EMR systems, admission discharge and transfer (ADT) systems, etc. are able to correlate transmitted device data with the location and/or patient assigned to that location.

Claims

1. A location detection system comprising:

a mobile patient support apparatus having a first unique identifier, a sensor, and a first wireless transceiver, the mobile patient support apparatus adapted to transmit via the first wireless transceiver the first unique identifier and a signal based on data from the sensor; and

a stationary module positioned at a known location within a facility, the stationary module including a second unique identifier and a second wireless transceiver adapted to receive the first unique identifier and the signal from the mobile patient support apparatus, the stationary module also including a third wireless transceiver adapted to transmit the first and second unique identifiers to a wireless access point of a computer network, and the stationary module further including a wired transceiver adapted to transmit the signal over a cable to a nurse call system.

2. The location detection system of claim 1 wherein the first and second wireless transceivers operate in accordance with Institute of Electrical and Electronics Engineers (IEEE) standard 802.15.1, and the third wireless transceiver operates in accordance with IEEE standard 802.11.

3. The location detection system of claim 1 wherein the stationary module further includes a fourth wireless transceiver, and the mobile patient support apparatus further includes a fifth wireless transceiver adapted to communicate with the fourth wireless transceiver.

4. The location detection system of claim 3 wherein the fourth and fifth wireless transceivers are infrared transceivers.

5. The location detection system of claim 1 wherein the signal indicates that a patient positioned on the mobile patient support apparatus may be exiting the mobile patient support apparatus.

6. The location detection system of claim 1 wherein the wired transceiver is in communication with a first port of the stationary module that is adapted to physically couple to a first end of the cable, and wherein a second end of the cable is adapted to physically couple to a second port of the nurse call system.

7. The location detection system of claim 1 wherein the mobile patient support apparatus is a bed, the sensor is a switch adapted to detect activation of a nurse call button on the bed, and the signal indicates that a patient on the bed desires to speak with a nurse.

8. The location detection system of claim 7 wherein the bed further includes a microphone, the bed is adapted to transmit audio signals from the microphone to the stationary module using the first wireless transceiver, and the stationary module is adapted to transmit the audio signals to the nurse call system via the wired transceiver.

9. The location detection system of claim 8 wherein bed further includes a scale adapted to detect a patient'"'"'s weight, the bed is adapted to transmit the patient'"'"'s weight using the first wireless transceiver, and the stationary module is adapted to transmit the patient'"'"'s weight to a server on the computer network using the third wireless transceiver.

10. The location detection system of claim 3 wherein the mobile patient support apparatus further includes a sixth wireless transceiver adapted to communicate with the wireless access point of the computer network, the stationary module is adapted to transmit the second unique identifier to the mobile patient support apparatus using the fourth wireless transceiver, and the mobile patient support apparatus is adapted to not communicate the second unique identifier using the sixth wireless transceiver.

11. The location detection system of claim 1 wherein the mobile patient support apparatus further includes a fourth wireless transceiver adapted to communicate with the wireless access point of the computer network, the mobile patient support apparatus adapted to transmit status data regarding the mobile patient support apparatus to the computer network using the fourth wireless transceiver.

12. The location detection system of claim 1 further comprising a second mobile patient support apparatus, wherein the stationary module is adapted to receive a third unique identifier from the second mobile patient support apparatus and transmit the second and third unique identifiers to the wireless access point.

13. The location detection system of claim 12 wherein the stationary module receives the third unique identifier via the third wireless transceiver.
