Abstract

A bed including a frame, a deck coupled to the frame and a communication network located on the bed has at least two modules connected to the network, at least one of those modules being able to provide an alarm message to the bed communication network.

Claims

1. A bed, comprising:

a frame;

a deck coupled to the frame; and

a communication network located on the bed and having at least two modules connected thereto, at least one of the modules being capable of providing an alarm message to the communication network.

2. The bed of claim 1 wherein the at least one module is a scale module.

3. The bed of claim 2 wherein the alarm message is responsive to a patient weight change exceeding or dropping below a preset level relative to an initial set point weight.

4. The bed of claim 1 including a module having a local alarm, the local alarm being responsive to the alarm message provided to the communication network.

5. The bed of claim 4 wherein the included module is a position sense module.

6. The bed of claim 4 wherein the alarm message provided to the communication network is selected from the group consisting of alarm messages related to patient bed exit, patient weight gain, patient weight loss, surface pressure loss and bed catastrophic failure.

7. The bed of claim 6 wherein the catastrophic failure is detected by a diagnostic tool coupled directly to an accessory port module.

8. The bed of claim 6 wherein the catastrophic failure is detected by a remote diagnostic tool coupled to an accessory port module by a data link.

9. The bed of claim 1 wherein the alarm message is received at a location remote from the bed.

10. The bed of claim 9 wherein the alarm message is provided to the communication network on the bed before arriving at the remote location.

11. The bed of claim 9 wherein the remote location is reached by way of a telephone line.

12. The bed of claim 9 wherein the remote location is reached by way of a hospital information network.

13. The bed of claim 12 wherein a communication module interfaces between the communication network on the bed and the hospital communication network.

14. The bed of claim 9 wherein the remote location is reached by way of a nurse call network.

15. The bed of claim 14 wherein a communication module interfaces between the bed communication network and the nurse call network.

16. The bed of claim 9 wherein a communications module and a remote information interface convey the alarm message to the remote location.

17. The bed of claim 2, comprising:

a load cell;

an analog to digital converter for converting an analog signal from the load cell to a digital signal;

a neuron controller for receiving the digital signal; and

a transceiver coupled to the controller and to the bed communication network for conveying the digital signals to the bed communication network.

18. The bed of claim 17 comprising a calibration/excitation relay for transmitting calibration data from the neuron controller to the analog to digital converter.
