Abstract

The Chest-positioner/pad Cardio Pulmonary Resuscitation System (CCPRS) provides improved resuscitation during one-person or two-person CPR. The simple, compact, portable and cost-effective system provides for manual, mechanical or electrical driven external chest compressions via a socket connection to a chest-positioner/pad unit. The chest-positioner/pad unit provides greater control of compression positioning providing adequate and reproducible chest compressions while preventing rib fractures and damage to vital internal organs. A module gives providers feedback to enable a provider to apply an appropriate compressive force in an appropriate direction, recurringly under emergency conditions. The present invention also provides improved blood circulation, oxygenation and gas exchange by expanding the chest past its normal relaxation point during diastole. Providers are able to administer adequate CPR for longer periods of time with reduced or minimal effort while improving survivability of cardiac arrest victims.

Claims

1. An apparatus for assisting with the administration of CPR to a patient comprising:

(a) a chest positioner unit conformable to the shape of a patient'"'"'s chest to position the apparatus on the sternum comprising a sternal pad that rests on the sternum of the patient, a socket for connecting with the chest compression device, and an elastic sheet having dimensions larger than the sternal pad or the socket and mounted between the sternal pad and the socket;

(b) one or more straps for securing a chest compression device to the patient'"'"'s chest;

(c) said chest compression device connected with the chest positioner unit, said device having arms connected with the device and extending laterally from each side of the device, each said arm having a first end pivotally connected with the device and a second end connected with one of said strap or straps; and

(d) a control assembly operably connected with the chest compression device to actuate the chest compression device to deliver chest compressions at a preferred stroke rate.

2. The apparatus of claim 1 wherein the chest positioner unit is radiolucent.

3. The apparatus of claim 1 wherein the chest positioner unit is electrically insulating.

4. The apparatus of claim 1 wherein the chest compression device is electrically actuated by the control assembly.

5. The apparatus of claim 1 wherein electrical actuation of the chest compression device moves the arms of the device from a rest position to an active position causing the strap wrapped around the chest of the patient to tighten and the chest compression device to apply a downward force to deliver an effective chest compression.

6. The apparatus of claim 1 wherein the chest compression device contains a pressure sensor.

7. The apparatus of claim 1 wherein the control assembly further actuates the chest compression device to deliver chest compressions at a preferred force.

8. The apparatus of claim 1 wherein the strap contains a rigid central section located at the back of the patient when the apparatus is employed.

9. The apparatus of claim 1 wherein the strap is connected with the chest compression device using tension-indicating hooks.

10. The apparatus of claim 1 further comprising a recoil spring for decompressing the chest beyond normal diastole position.

11. The apparatus of claim 1 wherein the recoil spring has a first end and a second end where the first end is connected with the rigid central section of the strap and the second end is connected with the chest compression device.
