Abstract

Abstract A device for performing cardiopulmonary resuscitation employs an applicator device (10) having a body (12) with an upper surface (18) and a lower surface (16). The lower surface (16) includes provisions for detachably securing to the patient's chest, such as a vacuum cup or an adhesive layer. For manual resuscitation, the upper surface will include a strap (20) or other means for securing a performer's hand thereto. For automatic applications, a mechanical drive member will be secured to the upper surface. By alternately pressing and lifting on the applicator device, the patient's chest can be compressed and expanded to improve induced ventilation and circulation.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 68 words
A device for performing cardiopulmonary resuscitation of a patient, comprising: an applicator body having an upper surface and a lower surface; means on the upper surface for securing a performer's hand or a drive member to the applicator; and means on the applicator body for adhering the lower surface to the patient's chest, whereby the patient's chest can alternately be compressed and expanded by operation of the device.
Claim 2
Dependent Claim 51 words
A device as in claim 1, wherein the means for adhering the lower surface to the patient's chest comprises a hollow interior in the applicator body, said hollow interior being open to the lower surface and the body being sufficiently flexible to allow the body to act as a vacuum cup.
Claim 3
Dependent Claim 22 words
A device as in claim 2, wherein a portion of the lower surface about the hollow interior is coated with an adhesive.
Claim 4
Independent Claim 17 words
A device as in any of the above claims, wherein the applicator body is a resilient pad.
Claim 5
Independent Claim 33 words
A device as in any of the above claims, further comprising an electrode disposed on the lower surface so that it will contact the patient's chest when the lower surface is adhered thereto.
Claim 6
Independent Claim 23 words
A device as in any of the above claims, wherein the means for securing a performer's hand is a strap or a glove.
Claim 7
Independent Claim 48 words
