The other end of air inlet pipe is provided with air inlet needle, and air inlet needle is pricked into bottle neck；Air bag can be in the presence of negative pressure to entering
The direction contraction distortion of valve；The deformation of air bag causes signal space to expand, so as to produce negative pressure, negative pressure signal is by connecing mouth 13
Pass to pressure sensor；When the pressure of the negative pressure in airflow space is less than the unlatching value of pressure check valve, pressure check valve
It is closed, when the pressure of negative pressure is more than the unlatching value of pressure check valve, pressure check valve could open air inlet.
When decoction, which flows away, causes the negative pressure that is produced in infusion bottle sufficiently large, the air in dynamic air inlet pipe and airflow space is inhaled
Into supplement so that air inlet pipe and airflow space also produce negative pressure, direction contraction distortion from air bag to suction nozzle；When air-flow is empty
Interior negative pressure continues to increase, and until the negative pressure in airflow space is more than the unlatching value of pressure check valve, pressure check valve is opened,
Extraneous air flows into airflow space and air inlet pipe, adds in infusion bottle, the pressure inside and outside infusion bottle is obtained balance, air

On switch start control device work, the pressure signal that control device is transmitted with 1-2 minute record pressure sensors first, control
The information such as signal intensity when air inlet frequency when device processed records normal infusion and air inlet, and by these information as base
Quasi- value, then, the pressure signal that control device constantly sends pressure sensor is compared with a reference value recorded, and is determined
Whether warning device alarm is opened.
During normal infusion, because bottle inner liquid medicine amount is sufficient, liquid level, which is not less than, draws liquid pin, and return-air is intermittent.Only when
When liquid level is declined to a certain extent, the negative pressure of suction air enough can be just produced in bottle, only negative pressure reaches to a certain degree, just meeting
Air-breathing, when air enters infusion bottle, make the pressure that decoction is produced and gas is produced in bottle pressure sum substantially with atmospheric pressure phase
Deng, stop suction, the at the uniform velocity lower drop input human body of decoction, until the negative pressure produced in bottle reaches that the degree of air-breathing just can be again again
Air-breathing.
When liquid level is less than air inlet syringe needle, due to the separation without liquid, in airflow space, air inlet pipe and infusion bottle
Air communication, therefore, when decoction continue to it is dirty when, air in infusion bottle can be made to produce negative pressure, it is empty in air inlet pipe and air-flow
Between will produce continuous negative pressure, when negative pressure be more than pressure check valve unlatching value when, pressure check valve open, extraneous air
Into airflow space and then enter infusion bottle, decoction is can continue to lower drop.
When airflow space produces negative pressure, negative pressure makes Direction distortion of the air bag to suction nozzle, signal space is produced negative pressure,
The signal that pressure sensor returns to control device is exactly continuous negative pressure signal, and signal frequency can also change, and work as control
When device detects continuous negative pressure signal and frequency and is higher than a reference value, control device opens warning device alarm, remind sufferer and
Nurse's transfusion is near completion.
When the signal intensity that control device monitors pressure sensor return is consistent with a reference value, but air inlet frequency is less than base
The half of quasi- value, opens warning device alarm, reminds sufferer and nurse, liquid-transport pipe-line because blocking causes transfusion speed to slow down.
