Abstract

A patient support apparatus includes a frame having a patient support deck. A footboard is removably coupled to the frame. A compression therapy module is located inside the footboard or is mounted to a foot section of the frame. A sleeve port is pneumatically coupled to the compression therapy module and is located on the foot section. The sleeve port is configured for attachment to at least one tube extending from a compression sleeve worn on a limb of a patient. Control circuitry is coupled to the frame and is operable to control functions of the patient support apparatus and to control the compression therapy module. A graphical display screen is coupled to the control circuitry and displays user inputs that are selected to control functions of the patient support apparatus and the compression therapy module.

7. The patient support apparatus of claim 1, wherein the compression module is permanently mounted to the footboard.

8. The patient support apparatus of claim 1, wherein the compression module carries a heater unit in the second interior region and the heater unit is operable to introduce heated air into a flow of air to the sleeve port.

9. The patient support apparatus of claim 1, wherein the footboard carries a heater unit in the first interior region and the heater unit is operable to introduce heated air into a flow of air to the sleeve port.

10. The patient support apparatus of claim 1, wherein the compression module carries a cooler unit in the second interior region and the cooler unit is operable to introduce cooled air into a flow of air to the sleeve port.

11. The patient support apparatus of claim 1, wherein the footboard carries a cooler unit in the first interior region and the cooler unit is operable to introduce cooled air into a flow of air to the sleeve port.

12. The patient support apparatus of claim 1, wherein software for interfacing with the compression module is stored in memory of the control circuitry prior to installation of the compression module in the footboard.

13. The patient support apparatus of claim 1, wherein software for interfacing with the compression module is stored in memory of the compression module and the compression module transmits the software to the control circuitry after installation of the compression module on the footboard.
