11 . The patient care system of claim 10 , wherein the retractor assembly is operatively attached to the height adjustment mechanism.
12 . The patient care system of claim 1 , further comprising a patient harness assembly including a plurality of straps configured to secure the patient to the patient support surface.
13 . The patient care system of claim 12 , wherein the patient harness assembly includes a multipoint waist buckle system.
14 . The patient care system of claim 1 , wherein the patient transport apparatus further includes a mattress defining the patient support surface to support the patient.
15 . The patient care system of claim 14 , wherein the retainer is configured to urge the collar, together with the driver of the chest compression system, towards the mattress such that the mattress compresses.
16 . The patient care system of claim 1 , wherein the tether includes a loop strap with a loop adjuster to selectively adjust a length of the loop strap.
17 . A patient care system for treating a patient, the patient care system comprising: a patient transport apparatus including: a base arranged for movement along floor surfaces, an intermediate frame arranged for movement relative to the base between a plurality of vertical configurations, and a patient support deck operatively attached to the intermediate frame and defining a patient support surface for supporting the patient; a chest compression system configured to provide automatic chest compressions to a patient, the chest compression system including: a driver having a driver body movably supporting a plunger arranged for providing chest compressions to the patient, and a driver frame with a base driver mount disposed on the patient support surface and lateral driver mounts extending between the base driver mount and the driver body to support the driver adjacent to the chest of the patient; and a retainer for securing the chest compression system to the intermediate frame of the patient transport apparatus, the retainer including: a collar shaped for releasable engagement with the driver of the chest compression system, a brace having: a mount operatively attached to the intermediate frame; and a post extending between: a first end operatively attached to the intermediate frame, and a second end operatively attached to the mount, a tether extending longitudinally and laterally between the mount and the collar to brace the collar, together with the driver of the chest compression system, relative to the intermediate frame of the patient transport apparatus, and a retractor assembly to adjust a length of tether between the collar and the mount.

Description

CROSS-REFERENCE TO RELATED APPLICATION The subject patent application claims priority to and all the benefits of U.S. Provisional Patent Application No. 63/291,696, filed on Dec. 20, 2021, the disclosure of which is hereby incorporated by reference in its entirety. BACKGROUND Cardiopulmonary resuscitation (CPR) is a lifesaving technique useful in many medical emergencies in which a patient's breathing and/or heartbeat has stopped, such as for example following a heart attack or a near drowning. Chest compressions are a primary aspect of CPR, and involve firmly compressing the chest of the patient to keep oxygenated blood flowing to the brain and other vital organs until more definitive medical treatment can restore a normal heart rhythm. The administration of CPR requires the effort and attention of a caregiver, such an emergency medical technician (EMT), who is consequently generally unable to perform other treatment modalities that may benefit the patient suffering the medical emergency. The caregiver may also need to put themselves in danger in order to administer CPR, such as during ambulatory transport of the patient. Devices have been developed which provide automatic chest compressions. One such device is the LUCAS™ family of chest compression systems, available from Physio-Control, Inc. This type of chest compression system utilizes a mechanical plunger to provide the chest compressions with the appropriate force and at the appropriate intervals. One notably useful application of the chest compression system is during transport of a patient supported on a patient transport apparatus, such as hospital bed, a stretcher, a cot, and the like. Additionally, it will be appreciated that providing automatic chest compressions during ambulance transport—often associated with high-speed driving, risky maneuvers, and/or hazardous road conditions—may mitigate the need for caregivers to perform CPR while standing unrestrained in a confined space. Due to the elevation of the patient support surface on which the patient is supported, especially during ambulatory transport, the caregivers or other treating medical professionals may need to closely monitor the stability of the chest compression system (and the patient) supported on the patient transport apparatus, and may need to provide attention to or otherwise manually assist with stabilizing and/or repositioning the chest compression system. As a result, the medical professionals may be inhibited from performing other types of treatment or patient cate. Moreover, in some circumstances, the caregiver may not be able to assist with stabilizing the chest compression system, and may have to attend to other types of treatment or patient care. A patient care system designed to address one or more of the aforementioned challenges is desired. SUMMARY The present disclosure provides a patient care system for treating a patient. The patient care system includes a patient transport apparatus, a chest compression system configured to provide automatic chest compressions to a patient, and a retainer for securing the chest compression system to an intermediate frame of the patient transport apparatus. The patient transport apparatus includes a base arranged for movement along floor surfaces, an intermediate frame arranged for movement relative to the base between a plurality of vertical configurations, and a patient support deck operatively attached to the intermediate frame which defines a patient support surface for supporting the patient. The chest compression system includes a driver having a driver body movably supporting a plunger arranged for providing chest compressions to the patient. The chest compression system further includes a driver frame with a base driver mount disposed on the patient support surface and lateral driver mounts extending between the base driver mount and the driver body to support the driver adjacent to the chest of the patient. The retainer includes a collar shaped for releasable engagement with the driver of the chest compression system, and a brace including a retainer mount and a tether. The tether extends longitudinally and laterally between the retainer mount and the collar to brace the collar and the driver of the chest compression system relative to the intermediate frame of the patient transport apparatus.
