Abstract
The utility model relates to a safe self-destroying syringe with a replaceable needle hub, comprising a core rod, an injection tube, the needle hub, a piston, a self-destroying piece and a steel needle. The self-destroying piece is connected with the steel needle and inserted in the needle hub. The syringe is characterized in that: the lower end of the needle hub is provided with a clamping ring; the joint of the injection tube and the needle hub is provided with a thread; the connection mode of the injection tube and the needle hub is in threaded connection; in use process, the needle hub, the self-destroying piece and the steel needle can be convenient replaced, which improves the safety of injection processes.
Description
[technical field]
This utility model relates to a kind of self-destruction syringe, specifically, is a kind of safety self-destructing syringe of replaceable needle stand.
[background technology]
Syringe is a kind of common medical instruments commonly used, and in order to avoid cross infection in the process of using syringe, syringe all changes disposable use into, and disposable syringe is widely used at present.Reused artificially in order to stop syringe, generally all be provided with self-desttruction equipment on the syringe.But existing self-destruction syringe only can prevent syringe and reuse that used syringe in processing procedure is easily stabbed human body owing to draw point is exposed at outward and caused courses of infection to a certain extent.
Self-destruction syringe in the market, its needle stand is secured on the injection tube, the connected mode of needle stand and injection tube is a snap fit closely, needle stand and injection tube are not easy to separate, and socket self-destruction part and draw point in the needle stand, in a part of actual injection, drawing liquid be injected into human body and need use separately draw point, promptly extract medicinal liquid and use a draw point, the injection human body uses a draw point, needle stand and injection tube is separated just can carry out and change draw point, so, the syringe that this existing needle stand and injection tube are fastenedly connected can influence the self-destroying function of syringe, even can't change the requirement of draw point when changing draw point.
[utility model content]
According to the shortcoming that exists in the prior art, this utility model provides the draw point pumpback formula self-destroyed syringe of a kind of replaceable draw point and self-destruction part.
The purpose of this utility model is achieved by following technical proposals.
A kind of draw point pumpback self-destruction syringe of replaceable draw point, comprise core bar, injection tube, needle stand, piston, self-destruction part and draw point, the self-destruction part connects draw point and is plugged in the needle stand, it is characterized in that: the needle stand lower end is provided with snap ring, injection tube and needle stand junction are provided with screw thread, and injection tube is to be threaded with the connected mode of needle stand.
Needle stand is given prominence on described self-destruction part top.
The set screw thread in described injection tube and needle stand junction is the square opening screw thread.
In this utility model, injection tube is threaded with needle stand, the junction of injection tube and needle stand is provided with screw thread, needle stand is provided with snap ring, needle stand is by the threaded engagement of its snap ring and injection tube and needle stand junction, needle stand is contained on the injection tube, self-destruction part and draw point are socketed in the needle stand, can quickly and easily needle stand be separated from injection tube like this, so needle stand that can more renew easily, self-destruction part and draw point, thereby make and use a secondary needle stand when extracting medicinal liquid, self-destruction part and draw point use a secondary needle stand with the injecting liquid drug human body time, self-destruction part and draw point, the safety that has improved injection process.The self-destruction part that connects draw point is located in the needle stand, and makes the outstanding needle stand in top of self-destruction part, can be convenient to mechanization like this and assemble syringe in batches.
[description of drawings]
Fig. 1 is this utility model structural representation;
Fig. 2 is this utility model cross section structure sketch map;
Fig. 3 is this utility model injection tube and needle stand syndeton sketch map.
Wherein among the figure 1, core bar; 2, injection tube; 3, piston; 4, needle stand; 5, self-destruction part; 6, draw point; 7, screw thread; 8, snap ring; 9, needle stand junction.
[specific embodiment]
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, this utility model is a kind of draw point pumpback self-destruction syringe, characteristics are to change needle stand, self-destruction part and draw point easily, thereby use a secondary needle stand, self-destruction part and draw point in the time of realizing extracting medicinal liquid, with the injecting liquid drug human body time, use a secondary needle stand, self-destruction part and draw point, the safety that has improved injection process.This utility model mainly is made up of core bar 1, injection tube 2, needle stand 4, piston 3, self-destruction part 5 and draw point 6, self-destruction part 5 connects draw point 6 and is plugged in the needle stand 4, injection tube 2 is provided with screw thread 7 with needle stand junction 9, needle stand 4 lower ends are provided with snap ring 8, injection tube 2 is to be threaded with being connected of needle stand 4, and its optimum thread connecting mode is the square opening thread connecting mode.Self-destruction part 5 and draw point 6 are plugged in the needle stand 4, and needle stand 4 is given prominence on self-destruction part 5 tops, can be convenient to mechanization like this and assemble syringe in batches.
Use of the present utility model is: at first, self-destruction part 5 connects draw point 6 and is socketed in the needle stand 4, needle stand 4 is threaded with injection tube 2, draw point 6 inserts medicine bottle and extracts medicinal liquid, and after extraction finished, needle stand 4 can be separated injection tube 2 easily, the needle stand 4 that more renews, self-destruction part 5 and draw point 6, in self-destruction part 5 and the draw point 6 socket inserting needle seats 4, needle stand 4 is threaded with the screw thread 7 of injection tube by the snap ring 8 of self again, just can inject human body afterwards.Use a secondary needle stand, self-destruction part and draw point when extracting medicinal liquid thereby can reach, use the purpose of a secondary needle stand, self-destruction part and draw point during the injection human body, the safety that has improved injection process.
