Abstract
The utility model discloses an injector special for blood plasma, which comprises a needle cylinder, a pushing rod and a piston, wherein the piston is arranged at the front end of the pushing rod to match with the needle cylinder, the inner wall of the needle cylinder is provided with a spiral convex body, and a groove is arranged on the cylindrical surface of the piston to match with the spiral convex body. When in use, the piston and the pushing rod are pushed forwards slowly in a rotating way, which is convenient for stable control of pushing speed, thereby enabling injection volume of the blood plasma to be stable and uniform, being beneficial to improving the effect of blood plasma injection and alleviating pain sensation brought by injection for patients.
Description
Technical field
This utility model relates to medical instruments, is specifically related to a kind of blood plasma special syringe.
Background technology
At present, the medical blood plasma injection conventional syringe of forming by syringe, push rod and piston that adopt more.This kind syringe exists the problem that fltting speed is difficult to stable control when being used for the blood plasma injection, can cause the blood plasma injection volume inhomogeneous, directly influences the effect of blood plasma injection.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of blood plasma special syringe of being convenient at the uniform velocity advance control is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of blood plasma special syringe, it includes syringe, push rod and is arranged on the piston that the push rod front end matches with syringe, the inwall of syringe is provided with the spiral type convex body, and the face of cylinder of the piston that matches with this spiral type convex body is provided with groove.
The preferred circular section convex body of above-mentioned spiral type convex body, the groove that cooperates with this convex body is the groove of circular section.
This utility model adopts the spiral type convex body is set on the syringe inwall, the syringe and the piston fit structure of the groove that the convex body on setting and syringe inwall on the face of cylinder of piston matches, when injecting, piston and push rod slowly rotate and advance, be convenient to the stable control of fltting speed, thereby make the injection volume stable and uniform of blood plasma, improve the effect of blood plasma injection, and can alleviate the pain that brings the patient by injection.
Description of drawings
Fig. 1 is this blood plasma special syringe structural front view;
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, this blood plasma special syringe includes the syringe 1 of splendid attire blood plasma, the push rod 2 that is used to promote blood plasma is installed in syringe, be equipped with at the front end of push rod 2 and cooperate the piston 3 that is used to seal blood plasma with syringe 1, the internal face of syringe 1 is provided with spiral type convex body 4, and the face of cylinder of the piston 3 that matches with spiral type convex body 4 is provided with groove 5.
The spiral type convex body 4 that this utility model is arranged on syringe 1 inwall can be square-section, trapezoid cross section, triangular-section or circular section, the section form that matches with convex body 4 is adopted in the cross section of groove 5, the spiral type convex body 4 of accompanying drawing embodiment is a circular section, and the groove 5 that cooperates with convex body 4 is the circular section groove that matches with convex body 4.
