Abstract
The utility model belongs to an improvement of medical equipment, in particular to a full-automatic magnetic pusher of an injector. The injector consists of three parts, namely an injector, a magnetic driver and a control circuit, wherein the magnetic driver generates magnetic force after being electrified to directly generate linear motion of a piston, and a transmission arm pushes a needle tube core to work. It has the functions of automatically pushing the needle tube to work, randomly controlling the injection speed and automatically powering off and stopping after the liquid is injected. The utility model discloses an use, alleviateed nurse intensity of labour, improved work efficiency greatly, make medical injection technique reach automatic level.
Description
This utility model belongs to a kind of improvement of medical apparatus and instruments, is specifically related to the full-automatic magnetic pushing machine of a kind of syringe.
Present intravenous injection mode be manually with the hands the pushing syringe needle tubing give the patient injection medicament, not only require great effort but also time-consuming, and it is suddenly big or suddenly small to advance dose when firmly uneven, cause suffering to patient, especially work efficiency is poor, a nurse once can only give a patient injection, and particularly the nurse can not break away from needle tubing during injecting, and other thing can not be done.
The purpose of this utility model just is to overcome above-mentioned deficiency, has designed the full-automatic magnetic pushing machine of a kind of time saving and energy saving syringe efficiently.
This utility model is realized that by following scheme it comprises syringe, magnetic force pusher and control circuit three parts.Syringe is made up of needle tubing fuse, needle tubing, movable snap ring, snap close, fixed screw, syringe needle plastic flexible pipe and syringe needle; The magnetic force pusher is made up of piston, stator casing, winding, winding skeleton, end cap, transmission arm and fixed screw; Control circuit is made up of little electric controller, executive circuit, power indicating circuit and work display circuit four parts.Magnetic force pusher piston directly acts on syringe needle tube fuse handle end by transmission arm on it, the pusher winding is linked to each other with control circuit by lead-out wire, and fixedly the movable snap ring fixed screw of snap ring and needle tubing, movable snap ring, active card ring lock are buckled and be fixed on the support that designs by fixed screw, stator respectively for whole magnetic force pusher stator and syringe needle tube.
Operation principle of the present utility model is as follows: after the control circuit energising, little electric controller produces pulse signal control executive circuit, executive circuit is supplied with magnetic force pusher winding working power, stator produces magnetic force, produce rectilinear motion at the magneticaction lower piston, and power is passed to the needle tubing fuse by transmission arm, and needle tubing fuse setting in motion, thus make the work of syringe start injection.
Novel advanced, simple in structure, the good looking appearance of the mode that the utlity model has, volume little (280mm * 160mm * 110mm), (2.5 kilograms) in light weight, cost are low, clean hygiene, working stability, safe and reliable, fault is few, the life-span is long, noise is little, little power consumption, be easy to advantage such as manufacturing.And the shutdown function of cutting off the power supply automatically after having an automatic promotion needle tubing, injection speed arbitrarily controlled and liquid having been annotated.
Further specify this utility model below in conjunction with accompanying drawing.
