CPR chest compression device with releasable base member

A cardiopulmonary resuscitation (CPR) device, comprising:

• a base member configured to be placed underneath a patient;
• a chest compression mechanism configured to deliver CPR chest compressions to the patient;
• a support leg configured to support the chest compression mechanism at a distance from the base member;
• a clamp mechanism coupled to the support leg and configured to attach the support leg to a lock component of the base member in a latch-closed configuration of the clamp mechanism and to release the support leg from the lock component in a latch-open configuration of the clamp mechanism;
• and
• a release mechanism coupled to the support leg and the clamp mechanism and configured to be pulled away from the base member and along the support leg in a direction substantially parallel to the support leg to disengage a wedge portion of the release mechanism from a wedge portion of the clamp mechanism by causing the wedge portion of the release mechanism to slidably engage the wedge portion of the clamp mechanism and to transition the clamp mechanism from the latch-closed configuration to the latch-open configuration, the release mechanism comprising a link portion connecting a pull ring to the wedge portion of the release mechanism.
