Description

A kind of passive infusion pump in medical application

Technical field

This utility model relates to a kind of infusion pump, especially relates to a kind of passive infusion pump in medical application.

Background technology

General infusion pump all needs power drives, when running into the non-transformer environment when operation in the open air (cause unexpected outage as earthquake, wind and rain etc., perhaps), tends to delay the treatment sick and wounded, causes serious consequence.

The infusion pump that notification number provides a kind of easy to carry, capable of telling time, constant temperature, can regulate infusion flow for the utility model patent of CN1462640, it is made up of electrothermal piece, bagger, air pump, flow meter and chronopher.Electrothermal piece directly connects alternating current power supply, be positioned at the bagger below, bagger matches with transfusion bag, and communicate with air pump by conduit, conduit is provided with flow meter, is used to measure the air pump throughput, chronopher is positioned at the air pump next door, connect dc source, air pump is an AC/DC, and its throughput is regulated by the potentiometer switch on next door.This infusion pump cooperates the transfusion of patient's Soft Roll bag, be applied to clinical in.

Notification number provides a kind of full automatic human body carry-on infusion pump for the utility model patent of CN2689958, it is made up of shell, wiring board, motor and tourelle etc., small machine drives several rollers and rotates, roller rotates extruding, squeeze bag inner liquid medicine rolling on the bottom plate is pushed out the input human body.

Publication number is that the application for a patent for invention of CN101116757 discloses a kind of transfer pump automatic pipe pressing device, comprise motor, gear-box, gear, gear, pressure pipe piece, on and off switch and Stroke Control module, gear is fixedlyed connected with motor rotation axis, gear is connected with the form of axle with screw thread, there is a touch switch gear upper end, and axle is connected with the pressure pipe piece, and an end of telescoping mechanism is connected with gear-box, the other end is connected with the pressure pipe piece, and there is a touch switch pressure pipe piece upper end; Along with the wearing and tearing of wriggling sheet, under the effect of telescoping mechanism, make tube for transfusion be in compacted state all the time in the work process, not only made things convenient for medical personnel's use, also avoided the generation of leakage, thereby eliminated the defective that human life is existed potential safety hazard.

Summary of the invention

The purpose of this utility model provides a kind of employing manpower and drives, and is applicable to the passive infusion pump in medical application of field work.

This utility model is provided with housing, handle, rotating shaft, clockwork spring, variator, drivewheel contact roller;

Housing is provided with the import and the outlet of passing for tube for transfusion; Rotating shaft is located in the housing, and an end of rotating shaft exposes outside the housing, and handle is located at and is exposed in the outer rotating shaft of housing, and rotating shaft and housing are rotationally connected; Clockwork spring, variator and drivewheel are located in the rotating shaft successively; Be interval with at least 2 on the outer marginal circumference of drivewheel and drive the liquid wheel, drive the liquid wheel and be rotationally connected with drivewheel; Contact roller is located in the housing, and contact roller is provided with at least 2, and contact roller is oppositely arranged with driving liquid wheel, and contact roller is provided with the spacing that the confession tube for transfusion passes with driving between the liquid wheel.

Drive the liquid wheel and preferably establish 4～10, contact roller is preferably established 3.Rotating shaft and housing are rotationally connected and preferably adopt bearing to be rotationally connected.

During operation, shake handle, rotating shaft is rotated, clockwork spring tightens up mechanical energy storage, after clockwork spring tightens up and puts in place, can decontrol handle, subsequently, clockwork spring can accurately release energy, variator speed governing output on request, drivewheel obtains required rotating speed and rotates, and follows drivewheel rotation and rotation but drive the liquid wheel, drive the liquid wheel and form rolling with contact roller, then the medicinal liquid in the tube for transfusion can flow on request.At last, medicinal liquid can inject human body by setting flow.

This shows that this utility model can reach and adopt manpower to drive, and need not the electric power equal energy source, is specially adapted to occasions such as field work and rescue and relief work.And this utility model is simple in structure, easy to carry, cost is low.
