Description

Micro infusion device control system
Technical field
The invention belongs to technical field of medical equipment, and in particular to a kind of micro infusion device control system.
Background technology
With the continuous development of electronic technology, the continuous renewal of Medical Devices, the infusion required precision to medical liquid medicine is got over Come higher, many medicines have strict requirements to infusion dosage, and this some drugs can not pass through physiological saline, glucose etc. It is diluted, so as to which traditional artificial needle tubing infusion can not ensure the accuracy of dosage.And this some drugs is because dose is smaller, It is also not suitable for being transfused for a long time using infusion pump.
At present, also there are some trace infusion instrument with electric, but be engaged only with electronic circuit with mechanical mechanism, use needle tubing Specification and pressure measxurement threshold value are all fixed from changing, and are influenceed to change the needle tubing of other specifications or receiving fluid density When needing to adjust threshold pressure, circuit parameter and mechanical structure must just be changed, it is very inconvenient.And this transfusion Device be open-loop rate control, by device, material, environment influenceed long-time stable work and precision controlling it is difficult to ensure that, entering Optional equipment is also needed to during row monitoring alarm, is made using being restricted.
So, there is provided a kind of micro infusion device is significant.
The content of the invention
The defects of for prior art, the present invention provide a kind of micro infusion device control system.
Micro infusion device control system, including microcontroller, button, display module, alarm module, motor driving core Piece, direct current generator, mechanism, infrared encoder are transfused, button, display module, alarm module, institute are connected with respectively on the single-chip microcomputer State and motor drive ic is also connected with microcontroller, the other end of the motorized motions chip passes through direct current generator and infusion mechanism It is connected, the direct current generator is also connected by infrared encoder with microcontroller.
Preferably, the microcontroller is C8051F020 single-chip microcomputers.
Preferably, the alarm module includes light emitting diode and buzzer.
Preferably, the motor drive ic is LG9110 chips.
Preferably, the infusion mechanism includes infusion device and exhaust apparatus.
Preferably, the display module is liquid crystal display.
Preferably, the display module is LCD liquid crystal displays.
Preferably, the resolution ratio of the LCD liquid crystal displays is 240 × 320 pixels.
Preferably, the total capacity of the infusion device is 5mL.
Micro infusion device control system provided by the invention, infusion amount and infusion can be set by button and liquid crystal display Speed, after the completion of setting, by single-chip microcomputer controlled motor driving chip, driving direct current generator promotes the operation of infusion mechanism, infrared Encoder feedback is transfused information, and after infusion amount reaches setting value, single-chip microcomputer control direct current generator stops operating, and works as infusion process When appearance such as blocks at the failure, warning system light emitting diode and buzzer are alarmed.Minimum infusion amount is 0.01mI, infusion essence Within degree reachable 5%.
Motor drive ic LG9110 every passage has 800mA continuous current fan-out capability, and it is right that peripheral circuit passes through LA, IB mouth input varying level, can correspond to OA, OB mouth difference output level, realize that direct current generator rotates and reverse,.Rotate forward real Function is now transfused, after the completion of decoction all infusion, reset function is realized by reversion.
When it is determined that transfusion value starts transfusion, the number of turns that direct current generator need to rotate is calculated by single-chip microcomputer, and by single-chip microcomputer control Motor drive ic processed rotates motor.Motor, which rotates, drives motor lead screw upper bush to advance, and sleeve promotes woven hose to advance, real Existing micro infusion, infrared encoder record motor turnning circle, feed back to the counter of single-chip microcomputer.When motor turnning circle reaches During predetermined value, single-chip microcomputer stops motor work.After terminating in infusion process with infusion, single-chip microcomputer passes through infrared encoder and monitors electricity Machine state, as motor does not rotate and causes infrared encoder no data in infusion process, or infusion terminates rear motor and not stopped operating Infrared encoder is caused to produce data, then system report infusion failure, is prompted by warning system.
