[0073] Further additional drawings are provided to clarify about what the counter force to the compression force is, which is a counter force to the reactive force arising in opposite direction to the compression force, with the said reactive force arising at the same time as when the compression force is being applied. This should not be confused with the compression pad and its rods return force provided by spring shown as 506 in FIG. 5 where I have called the said spring 506 as compression pad return spring.

[0074] I have tried to explain the counter force to resuscitation force with schematic diagrams for the sake of simplicity with FIG. 32 A showing a schematic diagram of the cpr device being placed on a ground 3200, with the cpr device being 3201, having enclosure box 3202 containing compression drive, a compression pad 3203, front part of frame 3204, connected to back part of frame 3205 having back pad or plate with said connection being by latch 3206, and into this frame a pumpkin 3207 is placed which is acted upon by compression pad 3203.

[0075] The compression action by compression pad on the pumpkin is shown in FIG. 3 B with arrow 3209 showing direction of compressive force, arrow 3210 shows direction of the reaction force which is opposite to the compression force and occurring at the same time as the compression force. FIG. 3B shows the compression force acting on the pumpkin resulting in the pumpkin getting compressed; notice the latch 3206 is fixed. Now disconnect the latch 3206 and thereby disconnect front part of frame 3204 from back part of frame 3205 and start the machine, what happens is shown in FIG. 3C The reactive force 3210 moves the front part of the frame, away from compressor pad and the pumpkin is not compressed, since a force to restrain the upper frame from moving is missing when latching is not done. Avoiding latching and fixing is essential to save time to start cpr assuming an untrained, low intelligence bystander has to connect the cpr machine and has to do it with in 3 minutes when the brain damage begins to start from hypoxia, 3 minutes as told to me by a cpr expert. So, when no latching is done the reactive force shown by arrow 3210 has to countered with an oppositely directed force, the said force being external to the device. This counter force is what has been called all along this patent document, as counter force to resuscitation force and this external force is provided by the weight of a rescuing person as described from the beginning to the end of this document.

[0076] FIG. 33 A shows the patient 3301 surrounded by the cpr device 3302 with upperpart of frame 3303 having enclosure box which has drive mechanism, and latch disconnected shown as 3304. FIG. 33B shows the front part of frame moving upwards as indicated by arrow 3305 under the influence of reactive force to the compression force while FIG. 33 B shows the front part of frame moving downwards under the force 3306 from weight of device. FIG. 34 shows the patient 3401 with the novel cpr device 3402 with seat 3403 and rescuer 3404 and arrows 3405 showing compression force, 3406 the reactive force and 3407 the counter force to the reaction force of compression force byway of the rescuers body weight.

[0077] Although the present embodiments have been described with reference to specific example embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the various embodiments.

[0078] In addition, it will be appreciated that the various operations, processes, and methods disclosed herein may be embodied in a machine-readable medium and/or a machine accessible medium compatible with a data processing system (e.g., a computer system), and may be performed in any order (e.g., including using means for achieving the various operations).
