Abstract
The utility model discloses a syringe, comprising an injection tube, a piston and a needle head, wherein the piston comprises a piston rod and a plug connected with the front end of the piston rod, the plug is in liquid sealing fit with the injection tube, the piston rod is in the screw thread fit with the injection tube, the width of the screw thread corresponds to the scale division at the outside of the injection tube, the piston rod is connected with a motor for controlling the piston rod to rotate. The utility model has the advantages that the injecting speed of medicine liquid can be controlled by the motor, thus decreasing the labor of medical staff and lightening the pain of the patient in injecting.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of injector for medical purpose.
Background technology
At present, conventional injector comprises injection tube, piston and syringe needle, when injection, normally with this syringe patient is injected, when promoting piston injection liquid medicine, because different people's strength differences by nurse or doctor, under different situations, so the firmly different speed that promote pistons can be not identical, still, promote the too fast or inhomogeneous meeting of speed of the speed of piston and bring pain to patient, so the speed that promotes piston need be controlled.
Summary of the invention
The purpose of this utility model is can not be controlled at the speed of the promotion piston of the existence of the conventional injector described in the background technology, can bring painful problem to patient, and a kind of syringe that can address the above problem is provided.
The realization the technical solution of the utility model is as follows:
A kind of syringe, it comprises injection tube, piston and syringe needle, described piston comprises piston rod and is connected in the plug of piston rod front end, liquid sealing cooperates between plug and the injection tube, it between piston rod and the injection tube threaded engagement, the width of screw thread is corresponding with the scale that is arranged at the injection tube outside, and piston rod is connected with control piston bar motor rotating.
Described injection tube is provided with the switch of control piston bar to the different directions rotation.
Described injection tube is provided with the switch of regulating piston bar rotating speed.
The beneficial effects of the utility model are that the speed of regulating the injector to inject medicinal liquid can reach best injection effect by the rotating speed of the piston rod of Electric Machine Control syringe, reduce patient's misery.
Description of drawings
Fig. 1 is a sketch map of the present utility model;
Among the figure, 1 is injection tube, and 2 is syringe needle, and 3 is piston rod, and 4 is plug, and 5 is scale, and 6 is direction switch, and 7 is speed switch.
The specific embodiment
With reference to a kind of syringe shown in the accompanying drawing 1, a kind of syringe, it comprises injection tube 1, piston and syringe needle 2, described piston comprises piston rod 3 and is connected in the plug 4 of piston rod 3 front ends, liquid sealing cooperates between plug 4 and the injection tube 1, be threaded engagement between piston rod 3 and the injection tube 1, the width of screw thread is corresponding with the scale 5 that is arranged at injection tube 1 outside, and piston rod 3 is connected with control piston bar motor rotating.Described injection tube 1 is provided with the direction switch 6 of control piston bar to the different directions rotation.Described injection tube is provided with the speed switch 7 of regulating piston bar rotating speed.The rotating speed of the piston rod 3 by the Electric Machine Control syringe, the speed of regulating the injector to inject medicinal liquid can reach best injection effect, reduces patient's misery.
