Cardiopulmonary resuscitation assist device
First Claim
1. A cardiopulmonary resuscitation assist device for providing cardiopulmonary resuscitation to the chest of a cardiac patient by an aid giver, comprising:
- a column member having an upper end and a lower end;
a suction cup member connected with said lower end of said column member, said suction cup member having an internal substantially concave surface facing away from said column member, said internal substantially concave surface being defined by a peripheral rim, said suction cup member being constructed of a resilient material;
defibrillation means connected with said column member for supplying defibrillating electrical shock to the chest of the cardiac patient; and
handle means connected to said column member between said upper end and said lower end thereof for providing a handhold substantially perpendicular with respect to said column member;
wherein the aid giver places said peripheral rim of said suction cup member upon the chest of the cardiac patient, then subsequently applies forces at said handle means alternately toward and away from the chest of the cardiac patient so as to provide cardiopulmonary resuscitation, the application of force away from the chest of the cardiac patient causing the chest of the cardiac patient to move with the suction cup member due to a suction effect between the suction cup member and the chest of the cardiac patient.

Abstract
A device providing performance of CPR without need to exert forces of such magnitude that the patient may be injured, and which further provides performance of defibrillation and ventilation. The CPR assist device according to the present invention is composed generally of an elongate column member, handles mounted normal to the column member, a suction cup member mounted at one end of the column member, and a defibrillation system so that the patient may be defibrillated in conjunction with CPR. According to the method of the present invention, an aid giver places the suction cup member of the CPR assist device on the chest of the patient, then grabs the handles and proceeds to alternately press on the chest and pull from the chest. The suction cup member causes the chest to compress and expand, thereby creating a churning action within the chest cavity that resuscitates the patient. An added benefit of the CPR assist device is that the expansion of the chest cavity as the suction cup member is pulled away from the chest will stimulate lung action of the patient. Defibrillation is provided by the aid giver actuating one or more switches on the column member which supplies electrical stimulation at electrodes mounted to the suction cup member. The defibrillation circuit may operate from household current or may be powered by an internal battery.

10. A method for providing cardiopulmonary resuscitation (CPR) to the chest of a cardiac patient by an aid giver, for use with a CPR assist device comprising a column member, a suction cup member connected to said column member, and a defibrillation means connected to said column member for supplying defibrillating electrical shock, comprising the steps of:
-
placing said suction cup member upon the chest of the cardiac patient; applying forces on said suction cup member alternately toward and away from the chest of the cardiac patient with a predetermined timing therebetween so as to provide cardiopulmonary resuscitation, the application of force away from the chest of the cardiac patient causing the chest of the cardiac patient to move with the suction cup member due to a suction effect between the suction cup member and the chest of the cardiac patient; and activating said defibrillating means to selectively apply a defibrillating shock to the chest of the cardiac patient while said suction cup member is adjacent to the chest during said period of predetermined timing between application of forces.
