It connects.In this way, motor 31 drives crank 32 to rotate, connecting rod 33 can push sliding block 34 to do on 35 surface of sliding rail and move up and down.
Oxygen system 4 is fixed in rack 1 such as Fig. 4, to the intermittent oxygen supply of patient in CPR.Specifically, for
Oxygen system 4 includes inlet suction port 41, air outlet adapter 42, solenoid valve 43, threeway 44, baroceptor 45, collection chamber 46 and air blast
Machine 47, inlet suction port 41 and air outlet adapter 42 are fixed in rack 3, three interfaces of threeway 44 be respectively communicated with inlet suction port 41,
Solenoid valve 43 and baroceptor 45, collection chamber 46 are respectively communicated with air outlet adapter 42, solenoid valve 43 and air blower 47, circuit control
Plate 5 is electrically connected with solenoid valve 43, baroceptor 45 and air blower 47 respectively.The external oxygen cylinder of inlet suction port 41 or concentration
Apparatus of oxygen supply is supplied oxygen using oxygen under normal circumstances；When baroceptor 45 detects oxygen pressure deficiency, control electricity
Road plate 5 controls air blower 47 and opens, and blasts fresh air, uses fed oxygen from air, carries in this way, oxygen when outdoor rescue can be solved
Measure insufficient problem.
Control circuit board 5 is connect with motor 31 and 4 signal of oxygen system respectively such as Fig. 5, as the full-automatic heart of the present invention
The control brain of lung resuscitating machine.
In During Cardiopulmonary Resuscitation, after pressing certain number, needing to stop is supplied oxygen to patient, and therefore, precisely detection is every
It once presses extremely important, further includes baffle 36 and photoelectric sensor 37 in the present invention, baffle 36 and sliding block 34 are fixed, light
Electric transducer 37 is fixed on sliding rail 35 and connect with 5 signal of control circuit board, slides into stroke most along sliding rail 35 in sliding block 34
When high point, 36 end of baffle is located at except 37 optical signal detecting channel of photoelectric sensor；Row is slided into along sliding rail 35 in sliding block 34
When the highest point Cheng Fei, baffle 36 is located within 37 optical signal detecting channel of photoelectric sensor.In this way, row can be run to sliding block 34
Journey highest point position can accurately count pressing each time as pressing initial position, so that it is determined that compressing time,
And then stops in setting time and supplied oxygen to patient.Specifically, further including two cover boards 38, two cover boards 38 cover be located at two sliding rails respectively
On 35, and crank 32, connecting rod 33, baffle 36 and photoelectric sensor 37 are placed in the enclosed space of cover board 38 and sliding rail 35, sliding rail
35 are rotatably connected with rack 1.In this way, shaded effect can be played, prevent ambient light interference photoelectric sensor 37 from working.In addition,
Sliding rail 35 is rotatably connected with rack 1, when not using full-automatic cardio-pulmonary resuscitation machine of the invention, can remove pressing mechanism 2,
Sliding rail 35 was fallen to, saving space hold parallel with rack 1 again.
CPR method of the invention, includes the following steps, when control circuit board 5 powers on, photoelectric sensor 37 is examined
Baffle 36 is surveyed whether within its optical signal detecting channel, baffle 36 within its optical signal detecting channel, controls if detecting
Circuit board 5 controls motor 31 and rotates, until baffle 36 is not within 37 optical signal detecting channel of photoelectric sensor.In this way, guaranteeing
When powering on, pressing plate 23 is at the highest notch position, facilitates and adjusts 23 height of pressing plate according to different chest thickness.
CPR method process of the invention is as follows, and photoelectric sensor 37 detects that baffle 36 is believed in its light twice in succession
Within number sense channel, it is considered as pressing plate 23 and performs a pressing operation；Pressing operation is continuously performed in pressing plate 23 to reach
When setting number, control circuit board 5 controls motor 31 and stops operating and control the output oxygen of oxygen system 4 or air.It will go
The position of journey highest point, can be with accurate calculation compression number as the Fixed Initial Point once pressed, and reaches setting in compression number
It is automatic to supply oxygen when value.
Specifically, baffle 36 is not examined in 37 optical signal of photoelectric sensor when the control motor 31 of control circuit board 5 stops operating
It surveys within channel.So, it is ensured that when being supplied oxygen, pressing plate is in extreme higher position, and preventing pressing plate 23 from squeezing thoracic cavity causes
Oxygen supply failure.
Specifically, control circuit board 5 controls, oxygen system 4 exports oxygen or the process of air includes, first control electricity
Magnet valve 43 is opened, and starts timing, then receives the real-time pressure data that baroceptor 45 transmits, and by real-time pressure data
It is compared with setting pressure data, when pressure data is more than setting pressure data and timing time reaches setting time, control
Solenoid valve 43 processed is closed, while controlling the rotation of motor 31, is executed " pressing-oxygen supply " next time and is recycled；It is lower than in pressure data and sets
When level pressure force data, control air blower 47 is opened, and is switched to fed oxygen from air mode, and when timing time reaches setting time,
It controls solenoid valve 43 and air blower 47 is closed, while controlling the rotation of motor 31, execute " pressing-oxygen supply " next time and recycle.
The foregoing is merely better embodiments of the invention, are not intended to limit the invention, all of the invention
Within spirit and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
