Abstract

The utility model provides an anti-pollution injector which comprises a needle cylinder and piston rod of which the outer end is provided with a pushing handle, wherein the periphery of the piston rod is provided with a telescopic sealing sleeve tube of which the outer end is hermetically connected with the pushing handle, the inner end of the sealing sleeve tube is hermetically connected with the upper opening part of the needle cylinder, the pushing handle in the sealing sleeve tube is provided with a ventilating hole which is provided with a sealing rubber plug, the outer side of the sealing sleeve tube is provided with a guiding holding handle of which one end is fixedly connected with the pushing handle, the other edge of the guiding holding handle is penetrated in a guiding hole of the outer side of the needle cylinder wall. The utility model has the advantages of simple structure and convenient use, prevents pollution because fingers are in contact with the piston rod and is used for intramuscular injection or physic liquor allotment.

Description

A kind of anti-pollution injector

Technical field

This utility model relates to a kind of medical supplies, refers in particular to a kind of anti-pollution injector that is used for intramuscular injection.

Background technology

At present, the intramuscular injection device that generally uses in the hospital is made up of urceolus and piston rod, and medical personnel are by the push-and-pull piston rod in operation, realizes operations such as aspiration medicinal liquid, admixing medical solutions, injection.But find that in use medical personnel are when carrying out operation such as aspiration medicinal liquid, admixing medical solutions, injection, finger can touch piston rod, causes liquid medicine injection to pollute easily.

Summary of the invention

The purpose of this utility model be to provide a kind of simple in structure, easy to use, can prevent to point a kind of anti-pollution injector that the contact piston bar pollutes.

The purpose of this utility model is achieved in that a kind of anti-pollution injector, comprise syringe and piston rod, be provided with handle in the piston rod outer end, wherein: described piston rod periphery is provided with telescopic Sealed casing pipe, the outer end and the handle of Sealed casing pipe are tightly connected, and the inner upper oral part with syringe of Sealed casing pipe is tightly connected; Be provided with passage on the handle in Sealed casing pipe, passage is provided with the sealing plug; Be provided with the guiding handle in the Sealed casing pipe outside, a wherein end of guiding handle is fixedlyed connected with handle, and another side is located in the pilot hole in the needle cylinder wall outside.

Guiding handle described in above-mentioned a kind of anti-pollution injector is made of two circular arc housings, is separately positioned on outside the Sealed casing pipe on piston rod both sides.

After this utility model adopts said structure,, can prevent from effectively that medical personnel from point directly to touch piston rod when operating syringe, avoid causing pollution, the assurance injection safety liquid medicine injection by telescopic Sealed casing pipe is set outside piston rod.

Description of drawings

Below in conjunction with the embodiment in the appended drawings this utility model is described in further detail, but does not constitute any restriction of the present utility model.

Fig. 1 is the structural representation of a kind of specific embodiment of this utility model;

Fig. 2 is a user mode sketch map of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of anti-pollution injector of the present utility model comprises syringe 1 and piston rod 2, be provided with handle 3 in piston rod 2 outer ends, be provided with telescopic Sealed casing pipe 4 in piston rod 2 peripheries, telescopic Sealed casing pipe 4 adopts organ type in the present embodiment, also can adopt diaphragm type; The outer end of Sealed casing pipe 4 and handle 3 are tightly connected, and Sealed casing pipe 4 inner upper oral parts with syringe 1 are tightly connected, and can form confined space like this, prevent that syringe from using the direct contact piston bar of finger; Be provided with passage 5 on the handle 3 in Sealed casing pipe 4, passage 5 is provided with sealing plug 6, and its effect is convenient for assembly in process of production; Be provided with guiding handle 7 in Sealed casing pipe 4 outsides, guiding handle 7 is made of two circular arc housings, be separately positioned on outside the Sealed casing pipe 4 on piston rod 2 both sides, fixedly connected with handle 3 in the upper end of guiding handle 7, the bottom is located in the pilot hole 1A in the syringe 1 wall outside, guiding handle 7 is to make things convenient for medical personnel can grip piston rod 2 outsides with hands in use, and does not influence the normal flexible of telescopic Sealed casing pipe 4, guarantees normally to use.

When this utility model specifically uses, consult shown in Figure 2ly, identical with the common syringe using method, medical personnel can grip the handle 7 that firmly leads with hands, can carry out suction, mixing or the injection operation of medicinal liquid; Because of the sealing function of telescopic Sealed casing pipe 4, can avoid liquid medicine contamination effectively.
