Abstract
An automatic intellectualized transfusion controller comprises a housing, a transfusion tube assembly, a mechanical control part and an electronic control part. The transfusion tube assembly is arranged in a channel which is equipped with a flux sensor at one side of the housing. A step motor drives a gear set to shift, a guide nut drives a guide screw to move up and down repeatedly, the guide screw drives a cam to press on the transfusion tube at one side of a regulation door to regulate the drops in the transfusion tube. Liquid level sensors are arranged at two sides of a clamp ring of a suspension bottle; signals which are collected by the flux sensor in the sensing channel go into a microprocessor for analysis processing and then control the step motor; while signals which are collected by the liquid level sensors go into the microprocessor for analysis processing and then give an alarm. With simple structure, reliable performance, small volume, the utility model which is convenient for carrying can control the flux of liquid dynamically, instantly and accurately with high speed of regulation and high precision for control. The utility model is very convenient for use, which is a new type automatic intellectualized transfusion controller.
Description
Technical field
This utility model belongs to the medical infusion control device, is specifically related to a kind of full-automatic intelligent transfusion controller.
Background technology
At present, adopt infusion pump to carry out the clinical transfusion monitoring to serious symptom and cardiovascular patient clinically, because the device structure complexity, governing speed is slow, and control accuracy is low, reports by mistake easily, influence patient's treatment, sometimes also may be because some unexpected factors produce serious consequence.In addition, the huge heaviness of this equipment volume is installed and used very inconvenience.
Summary of the invention
The purpose of this utility model provides the small and exquisite full-automatic intelligent transfusion controller that is exclusively used in transfusion control of a kind of volume.Can the liquid with precise control flow in the infusion process, and governing speed is fast, the control accuracy height.
Technical solution of the present utility model is: full-automatic intelligent transfusion controller is made up of shell, tube for transfusion assembly, mechanical control section and electronic control part.The tube for transfusion assembly is arranged on shell one side and is equipped with in the passage of flow transducer, and adjustment doors is equipped with in the passage lower end; The machinery control section is arranged on outer casing underpart, by motor driven gear group speed change, drives leading screw by the screw of final stage gear axis and does and pump, and leading screw lower end and cam arm are hinged, and cam is arranged on adjustment doors and tube for transfusion one side; The shell top is provided with the cantilever that clamps transfusion bottle, and liquid level sensor is equipped with in the snap ring both sides; The central processing unit of electronic control part adopts 8-bit microprocessor, after the signal of the flow transducer collection of induction channels enters the microprocessor analysis processing, and the control step motor; The signal of liquid level sensor collection sends warning after entering the microprocessor analysis processing.
During transfusion, by the medicine liquid droplet number that the input of panel control button is set, concrete numerical value shows by display screen.In the infusion process, the flow transducer in the induction channels is by the speed of dripping of liquid in the induction Murphy type tube, and the signal of generation is amplified into microprocessor analysis through shaping and handles, with the step-length of control step motor.Motor drives cam and is pressed on the tube for transfusion of adjustment doors one side by gear, the transmission of leading screw screw, and cam is regulated by microprocessor control step motor is dynamically instant the size of tube for transfusion applied pressure.When the pressure that is subjected to when tube for transfusion increased, flow rate of liquid diminished; When the pressure that is subjected to when tube for transfusion diminished, flow rate of liquid increased.Simultaneously, during infusing, when choking phenomenon occurring outside complying with one's wishes, medicinal liquid stops dripping, and pick off can be sent signal into microprocessor, sends warning by warning system.Transfusion bottle is installed on the snap ring of shell top cantilever, and the liquid level sensor that be equipped with the snap ring both sides is used to monitor the liquid level of bottle inner liquid medicine.When liquid level was lower than the height of setting, signal was sent into microprocessor, sent warning by warning system.
This utility model full-automatic intelligent transfusion controller architecture is simple, dependable performance, volume are little, easy to carry, can be dynamically, immediately, the liquid with precise control flow, and governing speed is fast, the control accuracy height is very easy to use.Adopt full-automatic intelligent transfusion controller can realize simultaneously that the numerical control system of dripping, the medicinal liquid accident of medicinal liquid stop dripping and three big functions of liquid level monitoring.This device cost of manufacture is low, be not only applicable to serious symptom and cardiovascular patient, all can adopt for general patient, so not only can avoid the malpractice that causes because of manual errors in the infusion process, simultaneously can also alleviate medical personnel's working strength greatly, be a kind of novel full-automatic intelligent transfusion controller.
