Abstract

Examples of the disclosure are directed to a patient support apparatus including a frame having a deck structured to support a patient, a retention device structured to secure the patient on the deck, and a compression device attached to the frame at the deck, the compression device including a compression mechanism structured to extend toward the patient and retract at least partially below the deck. In some examples, the compression device includes an inflatable bladder or a rotating cam having a lobe to provide the compression.

Claims (17)

1 . A patient support apparatus, comprising:

a frame including a deck structured to support a patient;

a retention device structured to secure the patient on the deck; and

a cardiopulmonary resuscitation (CPR) compression device attached to the frame at the deck, the compression device including a compression mechanism that includes a reciprocating plunger configured to deliver chest compressions to the patient, the reciprocating plunger structured to retract at least partially below the deck.

2 . The patient support apparatus of claim 1 , wherein the frame further includes a head rest structured to support a head of the patient in a prone position on the deck.

3 . The patient support apparatus of claim 1 , wherein the deck includes a compression aperture.

4 . The patient support apparatus of claim 3 , wherein the compression aperture includes a membrane covering the aperture.

5 . The patient support apparatus of claim 4 , wherein the deck includes a removable cover on the compression aperture.

6 . The patient support apparatus of claim 1 , wherein the retention device is rigid.

7 . The patient support apparatus of claim 1 , further comprising a retention device actuator operatively connected to the retention device and configured to regulate tension of the retention device.

8 . The patient support apparatus of claim 7 , further comprising a controller configured to drive the retention device actuator to regulate tension of the retention device in coordination with the compression mechanism.

9 . The patient support apparatus of claim 1 , wherein at least one of the compression device and the deck is structured to adjust in a plane parallel to the deck to adjust a compression point.

10 . The patient support apparatus of claim 1 , further comprising a sensor configured to detect a compression depth.

11 . The patient support apparatus of claim 1 , further comprising a power source configured to provide power to the compression device.

12 . The patient support apparatus of claim 1 , wherein the compression device is a first compression device, and the patient support apparatus further comprises a second compression device attached to the frame above the deck.

13 . The patient support apparatus of claim 1 , wherein the compression device includes an alignment mechanism.

14 . The patient support apparatus of claim 1 , further comprising at least two retention straps coupled to the frame, each retention strap structured to secure the patient on the deck.
