Abstract

A CPR device having a base member configured to be placed underneath a patient, a chest compression mechanism configured to deliver CPR chest compressions to a 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 a release mechanism coupled to the support leg and the clamp mechanism. The clamp mechanism may be configured to attach the support leg to a lock component of the base member in a latch-closed configuration and to release the support leg from the lock component in a latch-open configuration. The clamp mechanism may further be configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impinges upon an external portion of the clamp mechanism.

First claim

The invention claimed is:

1. 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 a patient;
a support leg configured to support the chest compression mechanism at a distance from the base member, the support leg having a receiving channel;
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 to transition the clamp mechanism from the latch-closed configuration to the latch-open configuration,
in which the clamp mechanism is further configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impacts an external portion of the clamp mechanism without the release mechanism being pulled away from the base member, and
in which the external portion of the clamp mechanism is separated from the lock component in the latch-closed configuration by a securing channel of the clamp mechanism, the securing channel and the receiving channel each being configured to accept at least a portion of the lock component in the latch-closed configuration, the securing channel of the clamp mechanism separating from the receiving channel of the support leg when the clamp mechanism transitions from the latch-closed configuration to the latch-open configuration.

2. The CPR device of claim 1 , in which the lock component comprises a rod attached to the base member at two ends of the rod, the clamp mechanism attaching to a middle portion of the rod between the two ends of the rod.

3. The CPR device of claim 1 , in which the lock component is at a first end of the base member, the first end of the base member being opposite a second end of the base member, and in which, to transition the clamp mechanism from the latch-closed configuration to the latch-open configuration, the clamp mechanism is configured to deflect in a direction toward a middle portion of the base member, the middle portion of the base member being between the first end of the base member and the second end of the base member.

4. The CPR device of claim 1 , in which the release mechanism comprises a pull ring configured to be pulled away from the base member.

5. The CPR device of claim 1 , in which the base member, the support leg, the clamp mechanism, and the release mechanism are made substantially of a radio-translucent material.

6. The CPR device of claim 1 , in which the clamp mechanism is pivotally connected to the support leg, and in which the release mechanism is coupled to the clamp mechanism by a wedge portion of the release mechanism in sliding engagement with a wedge portion of the clamp mechanism.

7. The CPR device of claim 6 , in which the release mechanism comprises:
a pull ring configured to be pulled away from the base member; and
a link portion connecting the pull ring to the wedge portion of the release mechanism, the link portion further comprising a spring tab extending from the link portion, the spring tab configured to contact the support leg and bias the release mechanism toward the base member.

8. The CPR device of claim 7 , in which the link portion further comprises a limiting slot, the limiting slot configured to interact with a protrusion extending from the support leg to limit motion of the release mechanism toward and away from the base member.

9. The CPR device of claim 1 , further comprising a bias element configured to apply a force to the clamp mechanism to bias the clamp mechanism in the latch-closed configuration.

10. 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 a patient;
a support leg configured to support the chest compression mechanism at a distance from the base member, the support leg having a receiving channel; and
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, the lock component comprising a rod attached to the base member at two ends of the rod, the clamp mechanism attaching to a middle portion of the rod between the two ends of the rod, the clamp mechanism further configured to transition from the latch-closed configuration to the latch-open configuration when the rod impacts an external portion of the clamp mechanism, the external portion of the clamp mechanism being separated from the rod in the latch-closed configuration by a securing channel of the clamp mechanism, the securing channel and the receiving channel each being configured to accept the middle portion of the rod in the latch-closed configuration, the middle portion of the rod being within the securing channel and within the receiving channel when the support leg is attached to the lock component of the base member, the securing channel of the clamp mechanism separating from the receiving channel of the support leg when the clamp mechanism transitions from the latch-closed configuration to the latch-open configuration; and a release mechanism coupled to the support leg and the clamp mechanism and configured to be pulled away from the base member to transition the clamp mechanism from the latch-closed configuration to the latch-open configuration.

11. The CPR device of claim 10 , in which the lock component is at a first end of the base member, the first end of the base member being opposite a second end of the base member, and in which, to transition the clamp mechanism from the latch-closed configuration to the latch-open configuration, the clamp mechanism is configured to deflect in a direction toward a middle portion of the base member, the middle portion of the base member being between the first end of the base member and the second end of the base member.

12. The CPR device of claim 10 , in which the release mechanism comprises a pull ring configured to be pulled away from the base member.

13. 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 a patient;
a support leg configured to support the chest compression mechanism at a distance from the base member, the support leg having a receiving channel; and
a clamp mechanism coupled to the support leg and configured to attach the support leg to a lock component at a first end 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, the clamp mechanism further configured to transition from the latch-closed configuration to the latch-open configuration when the lock component of the base member impacts an external portion of the clamp mechanism, in which, to transition the clamp mechanism from the latch-closed configuration to the latch-open configuration, the clamp mechanism is configured to deflect in a direction toward a middle portion of the base member, the middle portion of the base member being between the first end of t
