When the secondary frequency values fn for detecting receipts ripple is equal to the frequency values f0 of transmitted wave, the control valve of controller 4 shut-off woven hose 1.
The △ t are 3 seconds, 5 seconds or 7 seconds.
The operating frequency of the wave launcher 2 is that every △ t launch 1 time, and 2 milliseconds are continued every time.
The continuous several times of the frequency comparison operation device 5 detection received wave frequency values fn is equal to the number of times of emitted frequency value f0
For 3 times.
The ripple is ultrasonic wave, sound wave or infrasound.
The invention has the beneficial effects as follows：
1st, wave launcher of the invention is worked with the operating frequency after setting, and is worked 1 time such as per 1 second, and 2 millis are continued every time
Second, and the ripple of emitted during operation frequency values setting, it is possible to reduce the energy consumption of ripple transmitting, plays energy-conserving action, while reducing ripple
Action time, impact of the transmitted wave to woven hose inner liquid medicine is efficiently reduced, play safe effect.
2nd, frequency of the present invention using transmitted wave after through woven hose changes to calculate liquid flow velocity, according to meter
The flow rate of liquid value of calculation realizes regulation to transfusion speed come the tube valve that controls to infuse.
3rd, the present invention is repeatedly contrasted to ripple tranmitting frequency with the wave frequency rate, for receiving, if being repeatedly judged as ripple tranmitting frequency
During equal to the wave frequency for receiving, controller just turns off transfusion tube valve, is effectively prevented in transfusion incipient stage woven hose and there is gas
The erroneous judgement that bubble is produced, can eliminate interference and reduce erroneous judgement, it is ensured that efficiently.
4th, the present invention can in time have found to block up pin or find the excessively slow situation of the excessive velocities of some bursts.
