Abstract

A chest compression device with a chest compression belt assembly including guards and sensors operable with a control system to control operation of the system depending on detection of proper installation of the guards.

First claim

We claim:

1. A compression belt assembly for use with a chest compression device, said compression belt assembly comprising:
a compression belt;
a guard slidably disposed on the compression belt, proximate a first end of the compression belt, the guard comprising
a slot for slidably engaging the compression belt,
a fastener component configured to releasably secure the guard to a coordinating fastening element of the chest compression device in a position over an aperture of the chest compression device, and
a sensor component configured to indicate attachment of the guard to the chest compression device; and

a liner sock disposed about the compression belt and fixed to the guard.

2. The compression belt assembly of claim 1 , wherein the guard comprises:
a first portion having the slot for slidably engaging the belt, wherein the fastener component is connected to the first portion;
a second portion disposed at an angle to the first portion;
and
a second fastener component for securing the second portion to the chest compression device.

3. The compression belt assembly of claim 2 , wherein
the second fastener component is configured to secure the second portion over the aperture of the chest compression device.

4. The compression belt assembly of claim 3 , wherein:
the fastener component is a fixed component interoperable with the coordinating fastening element, the coordinating fastening element being disposed proximate the aperture of the chest compression device; and
the second fastener component is a flexible fastener component configured to be interoperable with a fixed fastener component disposed proximate the aperture of the chest compression device.

5. The compression belt assembly of claim 3 , wherein:
the fastener component comprises a cantilever snap fit beam for securing the first portion over the aperture in the chest compression device; and
the second fastener component is a flexible fastener component configured to be interoperable with a fixed catch component proximate the aperture of the chest compression device.

6. The compression belt assembly of claim 1 , wherein the sensor component is selected from one of a magnetic sensor, a contact relay, a contact switch, a capacitive sensor, an inductive sensor, an optical sensor, and an ultrasonic sensor.

7. The compression belt assembly of claim 1 , wherein the sensor component is configured to be interoperable with a second sensor component disposed in the chest compression device.

8. The compression belt assembly of claim 7 , wherein:
the compression belt is configured for releasably attaching to the chest compression device;
the second sensor component comprises a proximity sensor; and
the first sensor component comprises a proximity sensor target, wherein
the proximity sensor is configured to send a signal to a control system of the chest compression device indicating whether the proximity sensor target is detected, thereby indicating whether the guard is attached to the chest compression device, and
the control system is configured to control operation of the compression belt in response to the absence or presence of the proximity sensor target.

9. The compression belt assembly of claim 1 , wherein the guard comprises:
a first portion having the slot for slidably engaging the compression belt; and
a second portion configured for slidably engaging a second aperture of the chest compression device.

10. The compression belt assembly of claim 1 , further comprising:
a pin configured to fit into a corresponding slot in the chest compression device, said pin secured to the first end of the compression belt and oriented transversely to a length of the compression belt, said pin having a length greater than a width of the compression belt.

11. A compression belt assembly for use with a chest compression device, the compression belt assembly comprising:
a compression belt, said compression belt having a length and width, a first end and a second end, a longitudinal axis corresponding to the length of the compression belt, and a longitudinal edge on each side of the compression belt;
a guard slidably disposed on the compression belt;
a fastener component configured to releasably secure the guard to a coordinating fastening element of the chest compression device in a position over an aperture of the chest compression device; and
a first sensor component of a sensor, said first sensor component associated with the guard, wherein
said first sensor component is configured to be interoperable with a second sensor component disposed in the chest compression device for detection of attachment of the guard to the chest compression device.

12. The compression belt assembly of claim 11 , wherein the compression belt is configured for releasably attaching to the chest compression device.

13. The compression belt assembly of claim 11 , wherein the first sensor component is coupled to the guard.

14. The compression belt assembly of claim 13 , wherein said first sensor component comprises a protrusion configured to be interoperable with the second sensor component, wherein
the second sensor component is a contact switch disposed in the chest compression device.

15. The compression belt assembly of claim 13 , wherein said first sensor component comprises a magnet configured to be interoperable with the second sensor component, wherein
the second sensor component is magnetic sensor disposed in the chest compression device.

16. The compression belt assembly of claim 11 , wherein:
the first sensor component is configured to be detectable by the second sensor component, wherein
the second sensor component is configured to send a signal to a control system of the chest compression device indicating whether the first sensor component is detected, thereby indicating whether the guard is attached to the chest compression device, and
the control system is configured to control operation of the compression belt in response to the absence or presence of the first sensor component.

17. The compression belt assembly of claim 16 , wherein:
the second sensor component comprises a proximity sensor; and
the first sensor component comprises a proximity sensor target, wherein
the proximity sensor is configured to send a signal to a control system of the chest compression device indicating whether the proximity sensor target is detected, thereby indicating whether the guard is attached to the chest compression device, and
the control system is configured to control operation of the compression belt in response to the absence or presence of the proximity sensor target.

18. The compression belt assembly of claim 11 , wherein the detection of either the first sensor component by the second sensor component or the second sensor component by the first sensor component is configured to result in a signal being sent to a control system of the chest compression device indicating whether the first sensor component or the second sensor component is detected, thereby indicating whether the guard is attached to the chest compression device, wherein
the control system controls operation of the compression belt in response to said detection.

19. The compression belt assembly of claim 11 , wherein the first sensor component is selected from one of a magnetic sensor, a contact relay, a contact switch, a capacitive sensor, an inductive sensor, an optical sensor, and an ultrasonic sensor.
