Fig. 2 is a kind of flow velocity closed-loop control system block diagram of Self-controlled electronic analgesic transfusion pump device of the invention.
Specific embodiment
It is a kind of structured flowchart of Self-controlled electronic analgesic transfusion pump device of the invention as shown in Fig. 1.In figure, including master controller, occlusion detection module, bubble detection module, voltage stabilizing chip 1, voltage stabilizing chip 2, warning system, LCD display module, photoelectric sensor, mechanical transmission mechanism, direct current generator, key-press module, power module；Its structural feature is：The power module is connected by connecting voltage stabilizing chip 1 with the input of master controller, and power module connects the input of direct current generator by connecting voltage stabilizing chip 2；The signal input part of the master controller connects key-press module and photoelectric sensor respectively, the signal output part of the master controller connects occlusion detection module, bubble detection module, warning system, LCD display module, direct current generator respectively, the output end of the direct current generator connects the input of mechanical transmission mechanism, and the output end of the mechanical transmission mechanism connects the input of photoelectric sensor.
The power module uses dry cell, and it is the dry cell of 6V to use 4 section magnitudes of voltage.
Master controller of the present invention uses single-chip microcomputer MC9S12XS128；The photoelectric sensor plays an important role as mechanical driving part and the intermediate member of circuit control part, the control to infusion dosage and infusion velocity；In order to coordinate the use of photoelectric sensor, in the driven pulley of gear drive a circular hole of 3mm is opened near edge, when mechanical transmission mechanism is rotated, when the circular hole of driven gear is rotated in photoelectric sensing tank, the infrared signal that the light emitting diode of photoelectric sensor side sends is received by circular hole by the phototriode of photoelectric sensor opposite side, now phototriode conducting, low level is changed into from high level on colelctor electrode, produce a trailing edge to interrupt and be transmitted to master controller, master controller receives this trailing edge and interrupts the rotation for preventing direct current generator, then situation is rotated further according to concrete condition control direct current generator.
The occlusion detection module is made up of a rubber catheter and a microswitch, and the rubber catheter is attached on woven hose, and the microswitch is as in rubber tube；When choking phenomenon occurs in woven hose, liquid is just got into rubber tube, touches microswitch, produces the level saltus step of a trailing edge to be transmitted to master controller, and master controller is alarmed and stops the rotation of direct current generator, then carries out troubleshooting.
The bubble detection module is made up of air bubble sensor GK122 and amplifier circuit, and the air bubble sensor includes an infraluminescence LED pipe and an infrared photodiode；When there is bubble to pass through woven hose, the infrared signal that LED is launched is due to the influence of bubble, intensity can change, the voltage value changes for causing photodiode to receive, by being transmitted to master controller after amplifier TLC2272 amplifications, thus master controller can just judge to rotate and carry out relevant treatment with the presence of bubble, alarm immediately, stopping direct current generator in woven hose.
As shown in Fig. 2 being a kind of flow velocity closed-loop control system block diagram of Self-controlled electronic analgesic transfusion pump device of the invention.In figure, including photoelectric sensor, timer are controller, direct current generator, mechanical transmission mechanism, and it constitutes closed loop attachment structure；Direct current generator is controlled with pulse width variable pwm signal modulator approach, the positional information that mechanical transmission mechanism is rotated is acquired using photoelectric sensor；When mechanical transmission mechanism rotation is turned around, photoelectric sensor is imparted to one trailing edge saltus step of controller, controller receives the interruption of this trailing edge, to one low level signal of DC motor driver and start timer and start timing, after timing is arrived, give DC motor driver one high level signal, form certain frequency, the pwm control signal of certain dutycycle.
