Abstract

The invention discloses a micromotion injector. The micromotion injector comprises syringe needle parts, a liquid storage cylinder and a piston and is characterized in that the piston is provided with a tooth moving belt, a micromotion rotary knob is arranged on the liquid storage cylinder, the micromotion rotary knob is fixedly installed on the wall of the liquid storage cylinder, and the micromotion rotary knob is provided with teeth, wherein the teeth is meshed with the tooth moving belt. When the syringe needle parts are stabbed in a human body, the micromotion rotary knob is rotated, the force of the injection can be mastered easily, the force is convenient to conduct evenly, and meanwhile, the volume of injecta can be controlled accurately.

Description

A kind of fine motion syringe
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of fine motion syringe.
Background technology
In Western-style medical science, syringe is very common needle set, general needle set mainly comprises needle section, liquid storage cylinder, piston, when injection, can there is too fast injection or cross the firmly uneven situation of slow injection in people, too fastly likely make patient pain, firmly inequality causes speed different, allows patient enjoy especially and decocts.
Due to inequality of exerting all one's strength, also likely cause injection hypervolia or very few, be unfavorable for the accurate of medication.For abecedarian, medication inaccuracy is common Medical error.
Summary of the invention
The object of the present invention is to provide a kind of fine motion syringe, comprise needle section, liquid storage cylinder, piston, it is characterized in that: piston has the dynamic band of a tooth, liquid storage cylinder has a fine motion knob.
Described fine motion knob is packed on liquid storage casing wall, and has tooth and tooth and move band and be interlocked.
Beneficial effect is, after needle section is thrust human body, rotates fine motion knob, easily can grasp the dynamics of injection, conveniently exert all one's strength uniformly, can accurately control to inject liquid measure simultaneously.
Accompanying drawing explanation
Fig. 1: a kind of fine motion syringe simple structure schematic diagram
1, piston; 2, the dynamic band of tooth; 3, fine motion knob; 4, liquid storage cylinder; 5, needle section; 6, tooth.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing.
Embodiment 1:
Fine motion syringe as shown in Figure 1, comprise piston 1, tooth moves band 2, fine motion knob 3, liquid storage cylinder 4, needle section 5 and tooth 6 form, it is characterized in that a tooth being moved band 2 is packed on piston 1, the fine motion knob 3 simultaneously designing a band tooth 6 is packed on liquid storage cylinder 4 wall, when rotating fine motion knob 3, be engaged under the effect of tooth 6 that tooth moves band 2, piston moves upward downwards, can make the effect of liquid medicine injection, aspiration medicinal liquid.
Owing to being rotate to put forth effort, instead of vertically putting forth effort, can realize evenly putting forth effort, make to be that the medical personnel of abecedarian or more clinical experience control to exert oneself easily, medicinal liquid consumption.
Embodiment 2:
Fine motion syringe as shown in Figure 1, comprise piston 1, tooth moves band 2, fine motion knob 3, liquid storage cylinder 4, needle section 5 and tooth 6 form, the link design of piston 1 is it is characterized in that to become a tooth to move band 2, the fine motion knob 3 simultaneously designing a band tooth 6 is packed on liquid storage cylinder 4 wall, when rotating fine motion knob 3, be engaged under the effect of tooth 6 that tooth moves band 2, piston moves upward downwards, can make the effect of liquid medicine injection, aspiration medicinal liquid.
Owing to being rotate to put forth effort, instead of vertically putting forth effort, can realize evenly putting forth effort, make to be that the medical personnel of abecedarian or more clinical experience control to exert oneself easily, medicinal liquid consumption.
