Description of the Invention: [Technical Field] The present invention relates to a pneumatic control assembly, and more particularly to a pneumatic control assembly for a respiratory emergency device for converting a gas input from a source into A preset intermittent power output allows the entire air pressure control assembly to dispense with power supply equipment. [Prior Art] Cardio-Pulmonary Resuscitation (CPR) is a first-aid method of combining artificial respiration and artificial chest massage. It is often used for first aid in respiratory heartbeat caused by sudden accidents to maintain The normal use of first-aid breathing and cardiac rhythm functions 'enables blood to carry enough oxygen to the brain to sustain life. Artificial CPR has a certain method of implementation, because it is concerned about whether it can re-success in a very short time (usually only a few minutes) and then spontaneous breathing, or whether it can be in a very short time (usually about 4 minutes), After 4 minutes of advanced cardiac ambulance (AclS), and increasing the chances of survival, CPR implementation methods require high specification procedures and adherence to standards. These standards include the position and position of the rescued person; the position of the rescue, the gesture, the frequency, the strength, the time of execution, the uniformity and persistence of the exercise force, and the indispensability, so strict training and certification are required. Personnel can complete the rescue action more effectively. For example, when performing manual CPR, the rescuer must be fast, stable, and press the correct position of the sternum of the rescued person about 50 to 1 times per minute without interruption. It is very labor intensive. However, the usual on-site rescuers, those who meet the CPR qualifications, can not be met, coupled with the unpredictable factors such as the technical, physical and psychological fears of the rescuers, often seriously affecting the quality of rescue, can not provide The rescued person smashed and ~ 6 1342770 in the case of sexual compression 'often affects the effect of implementing CPR. Therefore, an electric CPR device that can overcome the artificial CPR defect has been gradually developed.

When it can be clearly understood: X First, the external money source passes through the air supply source 4, and enters the 1342770 start switch of the air supply device 31 respectively. 311, and after passing through the pressure regulating valve 36, enters the first two-way valve 332. 2. Next, the gas passing through the first two-way valve 332 will be made possible by the tube of the second gas path & or the tube 15 of the first gas path Pi because the original position of the first two-way valve 332 is different at that time. Entering the pneumatic cylinder 321 causes the piston to actuate. 3. Assume that the gas first enters the pneumatic cylinder 321 via the tube 15 and advances the piston to the second position I (such as the right side of the circle). At this time, the chest strap device 5 will be related to the relevant mechanism on the cpR device 100. Actuated to present a state of contraction, which in turn exerts a pressure on the chest of the first aided person. 4. When the left side of the piston is gradually increased due to continuous air intake, until the piston reaches the second position & (ie, the bottom dead center), the pressure setting of the air cylinder and the pressure regulating valve N will be the same because the piston cannot continue to advance. The intake pressure can be adjusted according to the setting. At this time, the chest strap device 5G will assume an appropriate tightening state, and the CpR device can be pressed to the chest of the first aid person as if the manual CPR is applied. It should be emphasized that, because the cpR device of the present invention is pressed into the chest of the first aided person, the pressure is pressurized by the pressure of the air pressure, so that the first responder can obtain both safety and safety. The comfortable pressing effect is not a risk that the prior art will rupture the chest of the first aid person by electronically controlling the mechanical pulse. The high voltage signal will transition to produce a pressure reduced second 12 to second reverse logic valve 3312. 6. At this time, a second signal tube 15 (first 5.

The air pressure control assembly 30 of the present invention can be activated. It should be noted that the CPR operation process and principle of the air pressure control assembly 30 of this embodiment are completely the same as the first embodiment described above, please refer to the foregoing. Please refer to FIG. 4, which shows a third embodiment of the present invention. This embodiment is also a further application of the first embodiment, which is mainly in the architecture of the first embodiment. , a counting device is added, the purpose of which is to provide a first-aid person to suspend the CPR device for a predetermined time after the CPR device presses the first-aid person a certain number of times, so that the emergency responder can cooperate with the artificial respiration or the respirator during the suspension period. anxious Breathing, is to provide a more complete first aid CPR rescue. In detail, the air pressure control assembly 30 further includes a counting device 35 in addition to the structure of the first embodiment, and pneumatically connects the air supply device 31 and the control device 33. After the actuating device 1342770 32 is actuated for a predetermined number of reciprocating motions, for example, after the actuating device 32 is scheduled to be actuated 30 times, the counting device 35 will cooperate with the output of a signal to the control device 33 to cause the immobilizing device 33 to suspend the actuating device. 32 - a predetermined time, wherein the predetermined time may be, for example, $ seconds. The counting device 35 of this embodiment includes a second two-way valve 351, a third bidirectional reading 352, a counter 353, a throttle valve 354, and an air reservoir 355. The second two-way valve 351 is pneumatically connected to the air supply device 31 and the second reverse logic read 3312. The third two-way valve 352 is pneumatically connected to the air supply device 31 and the second reverse logic valve 12, and has a third air path P3 and a fourth air path P4. When the air supply device 31 is switched to an open state, the air supply source 40 is adapted to be connected to the second reverse logic valve 3312 via the third air passage & Further, the counter 353 is pneumatically connected to the first two-way valve 351 and the third two-way valve 352. The throttle valve 354 is pneumatically connected to the fourth air passage P4 of the third two-way valve 352 and the counter 353. The air reservoir 355 is pneumatically coupled to the third two-way valve 352 and the throttle valve 354. The arrangement relationship of the other elements in this embodiment is substantially the same as that of the first embodiment described above, and the foregoing is not described herein. The operation process of this embodiment will be described in detail below. 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: 1 · Turn on the air supply device 31 The start switch 311 activates the gas supplied from the air supply source 40 to the pipe 5 via the pipe 9, and transmits it to the pipe 9-L and the pipe 9-R, respectively. 2. The gas passing through the tube 9-L flows through the third two-way valve 352 to the second reverse logic valve 3312. 3. The first reverse logic valve 3311 is congested via the gas of tube 9-R. 15 1342770 4. Assume that the original pneumatic cylinder 321 stays adjacent to the second position X〆, ie, at the bottom dead center) 'Because the air pressure in the right cylinder is low, the second low pressure signal will pass through the air passage P2 through the tube 12 Arriving at the second reverse logic valve 3312, the second reverse sequence 3312 will generate an opposite high pressure gas signal, that is, the second signal, to the first two-way valve 332 via the official 11 and the tube 14. 5. The second signal of the pressure will command the first two-way valve 332 to change the gas output position. From the first gas path ρι to the second gas path Pa, the gas is discharged, and the pipe 12 enters the pneumatic cylinder 321 and the right side guides the piston of the pneumatic cylinder 321 Moving to the first position X, the chest strap device 50 of the cpr device will assume a relaxed state. 6. The piston of the pneumatic cylinder 321 moves to the left to the first position Χ| (that is, the top dead center) stops, and at this time, the cylinder in the left side of the pneumatic cylinder 321 becomes low pressure due to the scarcity of the gas, and the first low pressure signal will pass through The tube 5 reaches the first reverse logic valve 3311. 7. After receiving the first low voltage signal, the first reverse logic valve 3311 generates a high voltage signal, and reaches the first two-way valve 332 via the tube 17, and commands the first two-way valve 332 to change the original gas supply direction to the first gas path P. |. Lu 8. Via the first gas path p, the gas of the tube 15 will enter the pneumatic cylinder 321 and move the pneumatic cylinder 321 to the other second position & direction, so that the chest strap device % changes from the relaxed state to the tightened state 'equivalent Applying the force state of CpR manually. As described above, since the pressure 疋 is applied to the chest of the first aid person in a gradually increasing manner, the emergency person can feel the safest and appropriate pressing effect of the party. 9. When the pneumatic cylinder 321 has reached the set pressure, the pneumatic cylinder 321 cannot continue to advance because of the relationship between the input air pressure and the internal air pressure balance of the pneumatic cylinder 321 , and the pressure on the right side of the pneumatic cylinder 32 ι will be lowered, and the low pressure second low voltage signal will be Further, the second reverse logic valve 3312 generates a second signal through the tube 11 and the tube 14 to the first two-way valve 332 via the tube 2 to the 16 1342770 two reverse logic valve 3312. 10. After receiving the second signal, the first two-way valve 332 changes the direction of the output gas from the tube 12 of the second air passage Pa to the right side of the pneumatic cylinder 321 , and guides the piston of the pneumatic cylinder 321 to move to the first position X1, and the chest bundle of the CPR device The belt device 50 will again exhibit a slack state, so that it will repeat. , U. The second signal outputted by the second reverse logic valve 3312 for indirectly controlling the operation of the pneumatic cylinder 321 φ will be from the Z end of the counter 353 via the tube 13, the second bidirectional valve 351, the tube 6 to the counter 353. Entering the second signal of each incoming counter 353 will increment the counter 353 for a predetermined number of times. For example, after a number of times, the counter 353 will send a high-voltage pause signal via the pipe 7 to the third two-way room 352. In order to change the air supply direction of the third two-way valve 352 through the third air passage, the original control gas cylinder 321 reciprocates the operation, and the third gas is supplied to the second reverse logic valve 3312. The road P3 is turned to the pipe 8 of the fourth gas path & and enters the number Y of the 353 force Y terminal, and the count of the original counter 353 set to be continuously operated 3 times is recorded as zero. On the other hand, another air flow through the tube 8 is passed through the tube to the throttling (four) and the air reservoir 355. 12. The flow rate of the gas flowing through the throttle valve 354 and the air reservoir 355 can be determined according to actual needs to suspend the reciprocating motion of the pneumatic cylinder 321 for a predetermined time. In the present embodiment, the predetermined time of the pause may be based on the flow rate and the dust force originally flowed by the gas flowing through the throttle width 354 and the air reservoir 355. For example, it takes about 5 seconds. After 5 seconds, the pressure of the tube 8·] will drive the third two-way between the third gas path P3, and then communicate with the gas supply device 31 and the second reverse logic valve plus 17 1342770. The pneumatic cylinder 321 is temporarily suspended. Reciprocating motion. 13.—But after the number of reciprocating actions of the barometric red 321 reaches 3 times, it returns to step 2, and so on. Next, please refer to Fig. 5, which shows a fourth embodiment to which the present invention is applied. This embodiment is incorporated in the architecture of the third embodiment, and the reset function of the aforementioned actuating device is added. - This reset function is completely identical to the reset function of the actuating device described in the second embodiment above. That is, the present embodiment incorporates a resetting device 34 in the structure of the third embodiment, φ which is pneumatically connected to the air supply device 3A and the control device 33. Specifically, in the embodiment, the first selection logic valve 341 is pneumatically connected between the first two-way valve 332 and the second reverse logic valve 3312 via the tube 6 and the tube 14, and is activated by the tube 2 and the air supply device 31.

This embodiment is to add a convenient first-aid operation and a more complete control function in the architecture of the fourth embodiment, which mainly strengthens the fourth implementation. The function of the air supply device in the example 'provides a control switch that is easy to operate using the CPR device of the present invention. In detail, the air supply device 31 of the present invention includes a start switch 311, a count 1342770 switch 312, a fourth two-way valve 313, and a second select logic valve 314. The start switch 311 is pneumatically connected to the external air supply source 4, the reset device 34, and the fourth two-way valve 313. The counting switch 312 is pneumatically connected to the air supply source 4A and the fourth two-way valve 313. The fourth two-way valve 313 is pneumatically connected to the start switch 311, the count switch 311, the counting device 35, and the first selection logic valve 314. The fourth two-way valve 313 has a fifth gas path J P5 and a sixth fluorine path P6. The second selector logic valve 314 is pneumatically coupled to the fourth bidirectional valve 313, the third bidirectional valve 352, and the first reverse logic valve 3311. The operation principle of the air supply device 31 of the present embodiment is as follows: 1. When the start switch 311 and the count switch 312 are simultaneously turned off, the air supply source 4 is adapted to activate the reset device 34 through the start switch 311, so that the actuating device 32 can be restored. To the return position. 2. When only the pressing function of the CPR device is activated without starting the counting function, the first-aider can only turn on the start switch 3U to make it communicate with the air supply source 4, and the gas of the air supply source 40 will pass through the fifth gas. The tube 4 is pneumatically connected to the second selection logic valve 314, and the gas is introduced into the first reverse logic valve 3311 of the control device via the tube 9 and the tube 9_R of the second selection logic valve 314 to activate the actuation device. One of the series of 32 operations, for example, 100 consecutive operations per minute, the operation principle of this continuous operation is the same as that of the foregoing embodiment, please refer to the foregoing, which is omitted here. 3. When the start switch 311 and the count switch 312 are simultaneously turned on, the start switch 3 ιι and the count switch 312 will be in pneumatic communication with the air supply source 4 at the same time, and the air supply source 4 气 will be pneumatically connected via the tube 5 of the sixth gas path P6. Up to the second selectable logic (4) 3M and the counting device 35'-the side causes the actuating device 32 to start acting, and on the other hand, the counting device ^ starts counting down, so that the CPR device provides, for example, every pure 丨 (9) times and every 3 〇 After 1342770 presses, the continuous operation is suspended for 5 seconds. Similarly, the operation principle of this mode is the same as that of the previous embodiment. Please refer to the foregoing. It should be emphasized that 'the present invention is applied to the air pressure control assembly 30 in the CPR device to apply various pneumatic valves' to provide a stable and progressive chest compression function by the first responder, and the CPR device using the present invention is not only one of the artificial emergency devices. Automated first aid devices, - and do not require the use of electricity as a driving force. Therefore, the present invention can not only reduce the influence of the environment on the operation of the system, but also avoid the failure of the general use of the circuit to control the high φ temperature and high humidity, improve the stability and reliability of the system operation, and The present invention can be widely deployed in a variety of public places to provide the necessary and timely CPR ambulance.
