Abstract

A medical support control system comprises a medical support having memory and a control system in connection with the memory and for connection with a component for use at the medical support. The medical support control system further includes a detection system configured to detect when the component is connected to the control system, such as the control system microprocessor.

First claim

We claim:

1. A patient support comprising:
a patient support based control system comprising:
memory; and
a microprocessor in communication with the memory;
a detection system detecting the presence of a load sensor at the patient support, the memory having stored therein a parameter associated with the load sensor, and the patient support based control system being operable to store information indicative of presence or absence of the load sensor at the patient support; and
when the detection system detects that the load sensor is present, the patient support based control system runs a calibration routine on the load sensor, and wherein the patient support based control system is configured to abstain from running the calibration routine based on the information being indicative of absence of the load sensor at the patient support.

2. The patient support according to claim 1 , wherein in the load sensor is a load cell.

3. The patient support according to claim 2 , wherein the patient support based control system generates an excitation current and applies the excitation current across the load cell to detect the presence of the load cell.

4. The patient support according to claim 3 , wherein the patient support based control system determines the state of the load cell to determine whether the load cell needs replacement.

5. The patient support according to claim 3 , wherein the patient support based control system determines the state of the load cell to determine the expected remaining life of the load cell.
