Please refer to FIG. 4, wherein the pipeline connection state between the components can be matched with the drawings and the following descriptions. When a clear understanding can be obtained: L turns on the air supply device 31. The switch 3U is activated to allow the gas supplied from the supply source 4 to flow to the tube 5 via the tube 9 and to the tube 9_L and the tube 9_R, respectively. 2. The gas passing through the official 9-L flows through the third two-way valve 352 to the second reverse logic valve 3312. 3 · X flows from the gas of tube 9-R to the first-reverse logic valve Du. 15 200916086 4. Assume that the original pneumatic cylinder 321 stays in the vicinity of the second position & (ie, at the bottom of the dead, due to the air pressure in the right side of the pneumatic cylinder 321 ' ώ ^ brother a low pressure signal will pass the = 2 through the tube 12 to reach the second The reverse logic valve 3312, at this time, the second reverser 3312 will generate an opposite high pressure gas signal, that is, the second signal, reaching the first two-way valve 332 via the official 11 and the tube 14.

1 (5) (4) - It is said that the first two-way valve 332 is commanded to change the gas output position U. The air path is changed to the second air path P2, and the pipe 12 enters the right side of the pneumatic cylinder 321 to guide the piston of the pneumatic cylinder 321 to the first position. The chest strap device 50 of the cpR device will assume a relaxed state. 6. The piston of the air pressure red 321 moves to the left to the first position & (ie, the top dead center) stops. At this time, the red air in the left side of the pneumatic cylinder 321 becomes low pressure due to the scarcity of the gas, and the first low voltage signal will be The first reverse logic valve 33U is reached via the tube 15. 7. After receiving the first low voltage signal, the first reverse logic valve 3311 will generate a high voltage signal 'to reach the first double (four) 332 via the tube π, and command the first two-way ^32 = to change the original gas supply. The direction is the first gas path P ]. 8. The gas passing through the tube 15 of the first air path P1 will move into the pneumatic cylinder 32 and move the pneumatic cylinder 321 to the other second position & direction, so that the chest banding device % is changed from the relaxed state to the tightened state, which is equivalent to a person. Wei exerts the force state of cpR. As described above, since the pressure is applied to the chest of the first responder in a gradually increasing manner, the rescued person can feel the safest and appropriate pressing effect. 9. When the pneumatic cylinder 321 has reached the set pressure, the pneumatic cylinder 321 cannot continue to advance due to the balance between the input air pressure and the internal air pressure of the pneumatic cylinder 321 , and the pressure on the right side of the pneumatic cylinder will be lowered, and the low pressure second low voltage signal will be again After the tube 2 to the 16th 200916086 two reverse logic valve 3312, the second reverse logic valve 3312 generates a second signal to reach the first two-way valve 332 via the tube 11 and the tube 14. 10. After receiving the second signal, the two-way valve 332 changes the direction of the output gas from the tube 12 of the second air path P2 to the right side of the pneumatic cylinder 321 and guides the piston of the pneumatic cylinder 321 to the first position to operate the chest band of the CPR device. Farming 5G will once again show a slack state, so it will be repeated. 11. The second signal sent by the second reverse logic valve to indirectly control the actuation of the pneumatic cylinder 321 is entered from the Z end of the counter 353 via the tube 13, the second bidirectional valve 351, the tube 6 to the counter 353', Each time the second signal of the incoming counter 353 is incremented, the counter 353 is incremented, and the number of times is up to a predetermined number of times. For example, after 3 times, the counter 353 will send a high-pressure pause signal via the pipe 7 to the third two-way valve 352. The air supply side of the third two-way valve 352 that has passed through the third air passage is changed: the operation of reciprocating the original control air cylinder 321 is stopped, and the third air path that originally supplied the air to the second reverse logic valve 3312 is stopped. & turns to the fourth gas path tube 8 and enters the count

The Y terminal ' of the L 353' sets the count record of the original counter 353 set to be continuously operated 3 times to zero. On the other hand, another air flow through the pipe 8 is said to be associated with the air reservoir 355 via f ^ to the throttle. The gas flow rate and pressure flowing through the Langliu 354 and the air reservoir 355 may be determined according to actual requirements to suspend the reciprocating motion of the pneumatic cylinder 321 for a predetermined time. In the case of this example, the predetermined time of this pause may be based on the flow of the gas flowing through the throttle and the gas reservoir = the current flow; the flow rate of the t and the house force, for example, about $ seconds. After 5 seconds, the pressure of the tube 8-1 will be the thief _ _ / / move 4 second two-way valve 352 switch the air path to the third gas path P3 'reconnect the gas supply device 3〗 and flute _ first The reverse logic valve 3312, following 17 200916086, continues the reciprocating motion of the pneumatic cylinder 321 originally suspended. 13. - However, after the number of times the pneumatic cylinder 321 reciprocates to reach 30 times, it returns to step 2, and so on.
