Abstract

Patient support apparatuses, such as beds, cots, stretchers, chairs, or the like, include wireless communication systems that are adapted to communicate with a non-local wireless receiver positioned outside of the healthcare facility and not associated with the healthcare facility. A computer positioned within the healthcare facility and coupled a local area network of the healthcare facility receives messages from the patient support apparatuses that have been forwarded by the non-local wireless receiver to the local area network. In some embodiments, the wireless receiver is local and positioned within the healthcare facility. In such instances, a second computer, such as a server, forwards a first subset of the patient support apparatus messages to a first computer via the local area network and a second subset of the patient support apparatus messages to a device remote from the healthcare facility. Patient support apparatuses that communicate using visible light are also disclosed.

First claim

What is claimed is:

1. A patient support apparatus for use in a healthcare facility having a local area network with a wireless access point, a server coupled to the local area network, and at least one network appliance adapted to communicate with both the local area network and a device remote from the patient support apparatus, the patient support apparatus comprising:
a support surface adapted to support a patient thereon;
a wireless transmitter adapted to transmit data to the server via a first path or a second path, the first path including the device remote from the patient support apparatus but excluding the wireless access point, the second path including the wireless access point but excluding the device remote from the patient support apparatus, the first and second paths each extending all of the way from the patient support apparatus to the server; and
a controller adapted to control when the wireless transmitter transmits data from the patient support apparatus to the server via the first path and when the wireless transmitter transmits data to the server via the second path.

2. The patient support apparatus of claim 1 further including a receiver in communication with the controller wherein the controller is adapted to transmit the data via the second path when the receiver detects a wireless signal from the wireless access point.

3. The patient support apparatus of claim 1 wherein the wireless transmitter is an RF transmitter adapted to transmit in at least one of the following frequency bands: 28 Gigahertz, 37 Gigahertz, and 39 Gigahertz.

4. The patient support apparatus of claim 1 wherein the controller is adapted to append an IP address to the data corresponding to an Internet-accessible server in communication with the network appliance, and wherein the device remote from the patient support apparatus is a receiver coupled to a cell phone tower, the receiver in communication with the Internet-accessible server.

5. The patient support apparatus of claim 1 wherein the device remote from the patient support apparatus is an Internet-accessible server positioned outside of the healthcare facility and in communication with the network appliance, and the controller is adapted to append an IP address to the data corresponding to the Internet-accessible server, the Internet-accessible server forwarding the data to the server via the network appliance.

6. The patient support apparatus of claim 1 further comprising a visible light emitter wherein the controller is further adapted to send the data to the device remote from the patient support apparatus using visible light.

7. The patient support apparatus of claim 1 wherein the data includes at least one of the following: a status of a brake of the patient support apparatus, a status of a siderail of the patient support apparatus, a weight of an occupant of the patient support apparatus, a height of a support surface of the patient support apparatus, and a state of an exit detection system of the patient support apparatus.

8. The patient support apparatus of claim 1 wherein the server is a patient support apparatus server adapted to share a subset of the data with another server coupled to the local area network.

9. The patient support apparatus of claim 8 wherein the another server is one of an Electronic Medical Records (EMR) server and an Admission, Discharge and Tracking (ADT) server.

10. The patient support apparatus of claim 1 wherein the data includes at least one of the following: (a) a number of times a motor on the patient support apparatus has been operated; (b) a current draw of a motor on the patient support apparatus; (c) a temperature of a component on the patient support apparatus; (d) an error signal from a component of the patient support apparatus; (e) a position of an actuator of the patient support apparatus; and (f) a software and/or hardware version of a component of the patient support apparatus.

11. The patient support apparatus of claim 1 wherein the controller appends a first address to the data when sending the data via the first path and appends a second address to the data when sending the data via the second path.

12. The patient support apparatus of claim 11 wherein the controller further appends a third address to the data, the third address corresponding to the server.

13. The patient support apparatus of claim 11 wherein the network appliance is one of a router and a gateway.
