Abstract

A cardiopulmonary resuscitation device which provides a combination of heart and lung compression by simultaneous compression of the heart and lung substance. The device may be rapidly installed on the patient with clip on straps which may already be in place where the patient is lying such as in an intensive care unit by merely pulling up on the straps and clipping onto the compressor which can be operated with a handle to simultaneously compress the heart and the lungs. The procedure may be continued for long periods of time without tiring the doctor or other person applying the resuscitation.

Claims

1. A cardiopulmonary resuscitator device for a patient formed of two separable components which will facilitate the immediate institution of resuscitation by an additive effect of both heart and lung compression comprising:

(1) a multibelted strong soft cloth-backed cuirass harness consisting of encircling strap means for ensuring lateral and vertical stability of an attachable chest compressor, a plurality of quick release means on each of said strap means;

(2) a portable attachable chest compressor with a padded compressor head which is operated manually by a multipositional rack and pinion drive, wherein said rack and pinion drive is actuated by an adjustable lever handle, and wherein said chest compressor can be quickly attached to said strap means by said quick release means, a plurality of tension-tightening sliding buckles attached to said strap means which can be adjusted to adequate tension to stabilize said padded compressor head over the lower, slightly leftward portion of the sternum of said patient so that actuation of said manual lever handle will cause simultaneously compression of the heart of said patient against the spine and portion of the adjacent posterior chest wall and, simultaneously said harness will compress the lungs and arrested heart of said patient with each chest compression stroke so that by compressing the lungs blood will move through the uncompressed heart, and an upright stabilizing handle attached to said chest compressor so as to stabilize said chest compressor as said lever handle is actuated.

2. A manual cardiopulmonary resuscitation apparatus according to claim 1 including an attaching pad which can be attached to a planar patient support, and means for attaching said cuirass to said attaching pad.

3. A manual cardiopulmonary resuscitation apparatus according to claim 2 wherein said means for attaching comprises hook and eye layers respectively connected to mating surfaces of said cuirass and to said attaching pad.

4. A manual cardiopulmonary resuscitation apparatus according to claim 1 including means for adjusting the length of travel of said padded compression head relative to said chest compressor.

5. A manual cardiopulmonary resuscitation apparatus according to claim 1 wherein said padded compressor head applies additive force for both heart and lung compression.

6. A cardiopulmonary resuscitator device according to claim 1 including means for adjusting the position of said lever handle relative to said pinion so that the position of said lever handle can be varied.
