Abstract
Abstract Portable apparatus is provided for use by a rescuer in administering cardiopulmonary resuscitation to a patient or for use as a training aid in the application of cardiopulmonary resuscitation. A light weight, inflatable, fluid-filled, foam or other resilient cushion has a pressure gauge attached thereto, and the cushion is placed on the patient's chest. Force is applied by the rescuer onto the cushion and the pressure gauge displays the force applied so as to enable the rescuer to observe and control the force being applied to the patient's chest. A timer may also be provided with the pressure gauge to enable the rescuer to properly time the application and release of force to the patient's chest.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
79 words
Apparatus for use in administering cardiopulmonary resuscitation to a human patient or for use as a training aid in the application of cardiopulmonary resuscitation, comprising: means for receiving manually applied forces; means in operative relationship with said receiving means for sensing said forces; means in operative relationship with said sensing means for indicating said forces; and a rigid member in operative relationship with said force receiving means for enabling substantially even distribution of said forces over a predetermined area.
Claim 2
Dependent Claim
79 words
Apparatus for use in administering cardiopulmonary resuscitation to a human patient or for use as a training aid in the application of cardiopulmonary resuscitation, comprising: means for receiving manually applied forces; means in operative relationship with said receiving means for sensing said forces; means in operative relationship with said sensing means for indicating said forces; and a rigid member in operative relationship with said force receiving means for enabling substantially even distribution of said forces over a predetermined area.
Claim 3
Dependent Claim
48 words
Apparatus in claim 1 further including timing means in operative relationship with said force indicating means for enabling said force indicating means to relax from a first predetermined reading to a second predetermined reading during a predetermined time interval when force is removed from said force receiving means.
Claim 4
Dependent Claim
22 words
Apparatus as in claim 1 wherein said force receiving means is configured to distribute said forces substantially evenly over a predetermined area.
Claim 5
Dependent Claim
24 words
Apparatus as in claim 3 wherein said force receiving means includes a resilient cushion and wherein said rigid member is attached to said cushion.
Claim 6
Dependent Claim
14 words
Apparatus as in claim 4 wherein said rigid member is a flat, platelike member.
Claim 7
Dependent Claim
51 words
Apparatus as in claim 5 further including first and second pieces of tape having adhesive applied to first sides thereof, each of said pieces of tape having a portion of said first side attached to said cushion and having a remaining portion of said first side attached to said platelike member.
Claim 8
Dependent Claim
30 words
Apparatus as in claim 1 further including means in operative relationship with said force receiving means for preventing sliding movement of said force receiving means relative to the patient's chest.
Claim 9
Dependent Claim
18 words
Apparatus as in claim 7 wherein said movement preventing means includes adhesive applied to said force receiving means.
Claim 10
Dependent Claim
16 words
Apparatus as in claim 8 further including a sheet removably attached to and covering said adhesive.
Claim 11
Dependent Claim
70 words
Apparatus as in claim 3 wherein said force receiving means includes an inflatable, walled cushion defining first and second interconnected chambers within the cushion; means in operative relationship with said cushion for enabling inflation thereof; and wherein said force sensing means includes a third inflatable, walled chamber located within said second chamber and defining a passageway in fluid communication with the interior of said third chamber and the ambient atmosphere.
Claim 12
Dependent Claim
22 words
Apparatus as in claim 10 wherein said force indicating means includes indicia on the cushion wall and on said third chamber wall.
Claim 13
Dependent Claim
49 words
Apparatus as in claim 11 further including timing means in operative relationship with said force indicating means for enabling said force indicating means to relax from a first predetermined reading to a second predetermined reading during a predetermined time interval when force is removed from said force receiving means.
Claim 14
Dependent Claim
40 words
Apparatus as in claim 11 wherein said third chamber wall defines a plurality of accordion-like pleats for enabling movement of said indicia on said third chamber wall along a substantially linear path when said third chamber is expanded and contracted.
Claim 15
Dependent Claim
25 words
Apparatus as in claim 11 wherein said rigid member is a flat, platelike member attached to said cushion in contiguous relationship with said first chamber.
Claim 16
Dependent Claim
30 words
Apparatus as in claim 14 further including means in operative relationship with said force receiving means for preventing sliding movement of said force receiving means relative to the patient's chest.
