End is equipped with a briquetting, and the briquetting can move down along the guide cylinder inner wall during declining and be pressed into human body cardiopulmonary
It recovers correct pressing position;During the CPR press device work, pressure is operated by operation panel input CPR
Power, according to pressing depth, compression frequency, then the microcontroller gas supply electromagnetic valve of the cylinder is controlled to open and is supplied to the cylinder
Gas, the cylinder piston rod elongation, makes the lever hinged with piston-rod end be rotated along itself and the upright bar hinge joint,
The connecting rod drives the briquetting of its lower end to decline, when the briquetting touches body surface, infrared induction mould
Block senses infrared signal, and at the same time the pressure sensor of the connecting rod upper end detects that pressure input data is big
In 0, the signal of generation is input to the microcontroller signal input part by the two, and then the microcontroller controls the displacement
Sensor carries out displacement measurement to change displacement coordinate point as displacement origin, reaches the according to pressing depth range of setting and press pressure value
Afterwards, the microcontroller controls the cylinder piston rod rapid desufflation to be restored to origin-location, and standard is done for pressing operation next time
It is standby.
Preferably, the cylinder gas supply gas is using nitrogen, gas pressure range 0.5-3MPa.
Preferably, the briquetting is disposably molded using elastic plastic material.
Preferably, the microcontroller can control the open frequency control compression frequency of the solenoid valve of gas supply air source.
Preferably, when the shift value of setting exceeds maximum safe displacement value or equipment fault output displacement value is pacified beyond maximum
During full shift value, the alarm module automatic alarm on the microcontroller control operation panel is shunk.
Preferably, when input pressure value exceeds maximum safety pressure force value or equipment fault output pressure exceeds maximum safety pressure
During force value, the microcontroller controls the alarm module automatic alarm on the operation panel.
Preferably, while the alarm module automatic alarm on the operation panel is reminded, the microcontroller controls institute
Cylinder piston rod rapid desufflation is stated to original position, equipment is out of service.
Compared with prior art, the present invention has the advantages that:The configuration of the present invention is simple, using infrared ray sensor
The pressing zero of contact human body is detected with pressure sensor dual combination, according to pressing depth range and press pressure value and by voltage-frequency
Rate can be exported accurately, displacement, the exceeded automatic alarm of pressure, and security performance is high, and first aid effect is good, and speed is responded using pneumatic control
Degree is fast, reliable operation.

Specific embodiment
The present invention is described further below in conjunction with attached drawing:
Embodiment:
As shown in attached drawing 1 to 4, the present invention provides a kind of CPR press device, which is characterized in that the CPR is pressed
Pressure device includes lever 1, upright bar 2, displacement sensor 3, microcontroller 4, pressure sensor 5, operation panel 6, infrared induction mould
Block 7, briquetting 8, guide cylinder 9, bottom plate 10, connecting rod 11 and cylinder 12;10 upper end of bottom plate is equipped with a cylinder 12, a guide cylinder
9,10 upper end of bottom plate between the two is equipped with a upright bar 2, and 1 centre position of lever and 2 top of upright bar are hinged, both ends respectively with
Connecting rod 11,12 piston-rod end of cylinder are hinged, and a microcontroller 4 is equipped in connecting rod 11, and 4 lower end of microcontroller is equipped with
One displacement sensor 3,4 side of microcontroller are equipped with an operation panel 6, solid between microcontroller 4 and the connecting rod 11 of lower end
A pressure sensor 5 is connected to, 11 lower end of connecting rod is equipped with a briquetting 8, and briquetting 8 can be along guide cylinder 9 during declining
Wall, which moves down, is pressed into the correct pressing position of human body CPR;It is defeated by operation panel 6 when CPR press device works
Enter CPR operating pressure, according to pressing depth, compression frequency, then microcontroller 4 control cylinder 12 gas supply electromagnetic valve open
It is supplied to cylinder 12, the elongation of 12 piston rod of cylinder makes the lever 1 hinged with piston-rod end turn along itself and 2 hinge joint of upright bar
Dynamic, connecting rod 11 drives the briquetting 8 of its lower end to decline, and when briquetting 8 touches body surface, infrared induction module 7 is felt
Infrared signal should be arrived, at the same time the pressure sensor 5 of 11 upper end of connecting rod detects that pressure input data is more than 0, the two
The signal of generation is input to 4 signal input part of microcontroller, then 4 command displacement sensor 3 of microcontroller is sat to change displacement
Punctuate carries out displacement measurement for displacement origin, and after reaching the according to pressing depth range of setting and press pressure value, microcontroller 4 controls
12 piston rod rapid desufflation of cylinder is restored to origin-location, prepares for pressing operation next time, and cylinder 12 supplies gas and uses
