Embodiment 5
As the 5th kind of embodiment of the invention, for the ease of counting to the number of pressing, the present invention staff is being propped up
The internal symmetry of support seat 1 is equipped with infrared light-emitting diode 4 and infrared receiving tube 5, as shown in figure 12, infrared light-emitting diode 4
Using the patch infrared transmitting tube of the model IR19-21C/TR8 of Guang Ling Electronics Co., Ltd., Zhongshan city production, infrared receiving tube
5 receive head using the patch of the model BH-5938-KN of Shenzhen Bo Sihong Science and Technology Ltd. production.
In the present embodiment, the detection front end circuit circuit diagram of infrared light-emitting diode 4 and infrared receiving tube 5 as shown at 13,
Infrared light-emitting diode 4 emits constant infrared ray under constant power drives, and infrared ray generates reflection by external object, so
Afterwards by infrared receiving tube 5, infrared receiving tube 5 generates pulse signal according to the strong and weak of the infrared signal received.
Specifically, the problem of because of infrared optical power, it is mV grades of electricity that the signal for receiving circuit generation is very small
Pressure, is amplified so having to pass through amplifying circuit, can just obtain the signal that can be identified, amplifier is amplified by integrated computation
The AC amplifier in the same direction that device LM324 is constituted, amplification factor:
AV=+1R4/R5,
Amplifying circuit circuit diagram is as shown in figure 14.
Further, the signal crossed by enhanced processing, high level, low level are not standard, cannot direct quilt
Single-chip microcontroller identifying processing, it is therefore desirable to non-type pulse signal is converted to using voltage comparator the pulse signal of standard,
Voltage comparator can compare input voltage with normal voltage, and lower than normal voltage, comparator exports 0 voltage, be higher than mark
Quasi- voltage, comparator output HIGH voltage in the present embodiment, is compared using integrated voltage comparator LM339 to do voltage, voltage
Comparison circuit modular circuit is as shown in figure 15, and R7 is potentiometer, and adjustment criteria voltage, R8 is pull-up resistor.
Since infrared receiving tube 5 and infrared light-emitting diode 4 are just opposite, when there is no push action, infrared light-emitting diode 4
It issues infrared light to be radiated on infrared receiving tube 5, infrared receiving tube 5 receives signal, low level is exported, when generation push action
When, 125 pairs of blocking infrared lights of bouncing ball of whereabouts, cause receive light intensity larger change, infrared receiving tube 5 cannot receive compared with
Strong signal generates a longer pulsation, but signal is smaller, is passing through after amplifying by an operational amplifier LM342
Over-voltage comparator LM339 can export a positive pulse signal and give singlechip interruption mouth, accordingly can be correct
The number for measuring pressing.

The CPR of meaning one presses training device, specific as follows:
S1, pressing training: trainer carries out simulation pressing positioning, after anchor point determines, training of human by salient point 21
Member presses palm on the anchor point in pressing plate 2, since 2 top surface of pressing plate is arc-shaped, is able to solve what pressing finger lifted
Highly, the finger contact simulation wall of the chest is avoided, ensures the normalization of operation, trainer presses downwards pressing plate 2, and pressing plate 2 is squeezed
1 deformation of support base is pressed, until pressing plate 2 touches on baffle 13, pressing plate 2 can not be fallen by the blocking of baffle 13 at this time, grasp
Make personnel's palm to be lifted up, by the elastic self-return of support base 1 itself, realizes a pressing job, while pressing plate 2
When pressing downwards, bouncing ball 125 supports in pressing plate 2 and slaps root press surface in the following, can control by the impetus of bouncing ball 125
Accuracy；
S2, pressing mechanism 12 use: when pressing plate 2 moves downward, pressing plate 2 supports to bouncing ball 125 and compresses the first bullet
Spring 124, and bouncing ball 125 moves downward, will push top cylinder 1265 retracts into second sliding slot 1264, and connecting cylinder 1263 is received
Contracting enters first sliding groove 1262；
S3, buffering: trainer is extracted limit plate 341 out by pull ring 342 out of groove 31, and by 341 band of limit plate
There is one end of inserted block 343 to be inserted into slot 14, limit plate 341 is snapped onto card slot 321 with one end of fixture block 344, when
When 1 stress of support base pulls down, pressure a part that support base 1 is subject to be will disperse to limit plate 341, and limit plate
341 pressure acts on limited block 32, and is dispersed by second spring 33.

6. CPR according to claim 5 presses training device, it is characterised in that: the connecting cylinder (1263) and institute
First sliding groove (1262) is stated to be slidably matched.
7. CPR according to claim 5 presses training device, it is characterised in that: the top cylinder (1265) and described
Second sliding slot (1264) is slidably matched.
8. CPR according to claim 1 presses training device, it is characterised in that: the top of the bottom plate (3) is leaned on
The positional symmetry of nearly two sides opens up fluted (31), and the inner wall of the groove (31) is equipped with second spring (33), and described second
One end of spring (33) is provided with limited block (32), offers card slot (321), the groove at the top of the limited block (32)
(31) inside is additionally provided with limiting device (34), and the limiting device (34) includes limit plate (341), the limit plate
(341) it is equipped at the top of pull ring (342), one end of the limit plate (341) is provided with inserted block (343), the limit plate
(341) the other end is provided with fixture block (344), and the outer wall of the support base (1) offers slotting close to the groove (31) side
Slot (14).
9. CPR according to claim 8 presses training device, it is characterised in that: the limit plate (341) and institute
State groove (31) clamping engagement.
10. CPR described in -9 any one presses training device according to claim 1, it is characterised in that: operating procedure
It is as follows:
S1, pressing training: trainer carries out simulation pressing positioning, after anchor point determines, trainer by salient point (21)
Palm is pressed on the anchor point on pressing plate (2), since pressing plate (2) top surface is arc-shaped, pressing finger is able to solve and lifts
Height, avoid finger contact simulation the wall of the chest, ensure the normalization of operation, trainer presses downwards pressing plate (2), pressing plate
(2) support base (1) deformation is squeezed, until pressing plate (2) touches on baffle (13), pressing plate (2) is by baffle (13) at this time
Blocking can not fall, and operator's palm is lifted up, and by the elastic self-return of support base (1) itself, realize one and press
Press work, while pressing plate (2) is downwards when pressing, bouncing ball (125) support in pressing plate (2) in the following, passing through bouncing ball (125)
Impetus can control the palm root press surface accuracy；
S2, pressing mechanism (12) use: when pressing plate (2) moves downward, pressing plate (2) supports to bouncing ball (125) and compresses the
One spring (124), and bouncing ball (125) moves downward, will push top cylinder (1265) retracts into second sliding slot (1264),
Connecting cylinder (1263) retracts into first sliding groove (1262)；
S3, buffering: trainer is by pull ring (342) extraction out of groove (31) by limit plate (341), and by limit plate
(341) one end with inserted block (343) is inserted into slot (14), and limit plate (341) are caught in the one end of fixture block (344)
To in card slot (321), when support base (1) stress pulls down, pressure a part that support base (1) is subject to will disperse to
On limit plate (341), and the pressure of limit plate (341) acts on limited block (32), and is dispersed by second spring (33).
