The specific workflow of this intelligent transfusion supervising device：
When transfusion starts, on one section of tube for transfusion 4 that the device is clipped in above Mo Feishi droppers 1, turn on the power 13 and open
Close and push button 12, device will be into sampling process.This process microprocessor 11 will be recorded to be sent by signal generating circuit
, and the pulse signal frequency value corresponding with liquid medicine in pipe.Afterwards in whole infusion process the timing of microprocessor 11 to arteries and veins
Signal sampling is rushed, by analyzing in intervals, the size of the difference of pulse signal frequency change has judging tube for transfusion 4
Without liquid medicine.Push button 12 after the liquid medicine for more renewing, device will enter sampling process from newly, and record and Guan Zhongxin liquid medicine
Corresponding pulse signal frequency value.Therefore this detection method has adaptive feature, can be suitably used for various liquid medicine, and detection is accurate
It is really reliable.
Device will go into normal monitor state after sampling process.When in detecting tube for transfusion 4 without liquid medicine, should
Device drives first wireless module alarm signal to be sent to nurse station, afterwards microprocessor 11 to motor driver signal driving
Dynamic motor 10 operates, and pressed slider 6 starts to left movement and by tube for transfusion 4 to compress, so as to reduce medicinal liquid flow velocity；Work as medical care
Push button 12 when personnel come, the device drives first wireless module to send alarm signal is released to nurse station, Zhi Houwei
To motor driver signal with the operating of the opposite direction of drive stepping motor 10, pressed slider 6 starts to move right processor 11, works as pressure
When tight slide block 6 touches travel switch 8, it will to the signal that 11 1 current potentials of microprocessor are dragged down, now motor 10 stops
Only operate, the stop motion of pressed slider 6.Medical personnel push button after being disposed and 12 restart work, or shutdown.Work
During, LED light is gone out using Chang Liang, often, flashes carry out indicating operating status at a time interval.
Due to the needle diameter very little of tube for transfusion 4, if wanting accurately control drop speed is accomplished by precise control to tube for transfusion 4
Thrust, so not only realizes difficulty, and can greatly increase the cost of whole device.To overcome this difficult problem, this practicality is new
The flow rate control method of type is realized by the extruding step to tube for transfusion 4 of pressed slider 6 and release.Realize principle：Due to
Mo Feishi droppers 1 are softer with buffering effect, therefore when pressed slider 6 compresses tube for transfusion 4 completely.Due to Mo Feishi droppers 1
In there is a certain amount of air, the liquid medicine in 1 time end pipe of Mo Feishi droppers can't stop immediately, but receive in Mo Feishi droppers 1
While pressure volume-diminished, drop speed is decrease continuously to stop；When pressed slider 6 unclamps, air is entered by the upper end of tube for transfusion 4 again
In entering Mo Feishi droppers 1, liquid medicine restarts lower drop in pipe, and again experience drop speed is decrease continuously to the process for stopping.This reality
The method for being extruded with new employing batch (-type) and being unclamped is actual that a comparatively ideal flow velocity control has been obtained at the syringe needle of tube for transfusion 4
Effect processed.On the premise of avoiding causing stifled pin, extend remaining liquid medicine in Mo Feishi droppers 1 and drip off the required time, leave for
Medical personnel's sufficient time is processed.
A kind of intelligent transfusion monitoring method of controllable infusion flow velocity that above-mentioned intelligent transfusion supervising device is realized, it is special
Levying is, comprises the steps：
2 metallic laminas are clamped in the wall both sides of tube for transfusion 4 by step 1, and 2 metallic laminas form measured capacitance CX；Micro-control
There is the switching tube S2 of circuit in device output certain frequency pulse signal control signal processed, realization is constantly charged to measured capacitance CX
And electric discharge；
Step 2, the real time record signal generating circuit of microprocessor 11 is sent, and corresponding with liquid medicine in tube for transfusion 4
Pulse signal frequency value；When in the tube for transfusion 4 between 2 metallic laminas from there is liquid medicine to be changed into without liquid medicine, the electricity of measured capacitance CX
Capacitance will change, and now the change transitions of measured capacitance CX capacitance are pulse signal frequency by signal generating circuit
Change, and send in microprocessor 11；
Step 3, when microprocessor 11 is detected in tube for transfusion 4 without liquid medicine, is signaled to immediately motor drive module,
Motor drive module drive stepping motor 10 realizes forward and reverse being alternately rotated；Meanwhile, drive wireless transmitter module and/or warning mould
Block works, and wherein wireless transmitter module sends signal to nurse station and sends alarm signal, and alarm module then directly sends alarm signal
Number.
Step 4, the drive screw 7 of 10 Jing decelerators of motor 9 works, and screw mandrel 7 switchs to the rotary motion of motor 10
Linear motion, and drive pressed slider 6 to produce straight reciprocating motion, so as to realize the extruding or release of tube for transfusion 4；In this process
In, whether the detection pressed slider 6 of travel switch 8 returns to reset state, i.e., can when pressed slider 6 touches travel switch 8
Signal is dragged down to 11 1 current potentials of microprocessor；Microprocessor 11 receives current potential and drags down after signal, and control motor 10 stops
Only operate.
Step 5, when pressed slider 6 travels forward, the tabletting of the head of pressed slider 6 extrudes tube for transfusion 4, tube for transfusion 4
In liquid medicine drop speed be decrease continuously to stop；When pressed slider 6 is moved backward, the tabletting of the head of pressed slider 6 will infuse
Pipe 4 unclamps, and the liquid medicine in tube for transfusion 4 restarts lower drop；So move in circles, until manually intervening its infusion process
(such as stopping infusion changes infusion bottle).
This utility model can reliablely and stablely complete the negative of the monitoring to infusion process, mitigation patient and caregiver
Load, and any pollution will not be produced to medicinal liquid.The Chinese medicine water flow velocity of tube for transfusion 4 can be reduced when transfusion is completed, is avoiding making
Into stifled pin on the premise of, extend remaining liquid medicine in Mo Feishi droppers 1 and drip off the required time, leave for medical personnel it is sufficient when
Between processing.
