Abstract

The utility model discloses a plastic-glass disposable syringe with medicine soup, comprising a glass needle cylinder, a plastic push bar, a silica gel lutation piston, the injection physic liquor and a hub cap. The hub cap is sheathed on the hub of the glass needle cylinder hermetically. The silica gel lutation piston is fixed at the front part of the plastic push bar and has a tight fit with the inner bore of the glass needle cylinder, and the silica gel lutation piston can be pumped hermetically in the glass needle cylinder. The injection physic liquor is loaded in the glass needle cylinder and exists in a space formed by the silica gel lutation piston and the hub cap. The glass needle cylinder is provided with a dial for indicating the capacity of the injection physic liquor. The glass and the silica gel can not pollute and change the property of the injection physic liquor, so the utility model is the storing bottle of the injection physic liquor as well as a hypodermic syringe. So long as the silica gel hub cap is extracted and a disinfected syringe needle is arranged, the plastic-glass disposable syringe with medicine soup can inject directly, which not only has convenient use and saved physic liquor but also is sanitary, economical and practical.

Description

What carry medicinal liquid moulds the glass disposable syringe

Technical field:

This utility model relates to a kind of medical apparatus, relates in particular to a kind of syringe.

Background technology:

The syringe that generally uses has two classes now, and a class is reusable syringe, and the material of its syringe and push rod is glass, and the cylindrical of push rod and the endoporus of syringe are all necessary through Precision Machining, and reach specific quality of fit; Another kind of is disposable syringe, and it is made up of syringe, push rod, sealing member, and sealing member is arranged on the front end of push rod, and sealing member is sealably twitched in syringe, and the material of its syringe and push rod is plastics.This two classes syringe all must be loaded onto the syringe needle of sterilizing in use, opens the vial that is equipped with by injection medicament, and could inject after sucking medicinal liquid in the syringe.Because existing injection all comes fill by the used dosage of adult, when using, the child only needs wherein half, and this must cause the waste of injection medicament.Conventional injector is when having an injection to patient, should purchase to join and irritate the filling bottle that the injection medicinal liquid is arranged, use syringe again, not only use loaded down with trivial detailsly, and imbibition and injection process be difficult to guarantee the accuracy of injection volume, and be easy to generate the secondary pollution of injection medicinal liquid, thereby influence therapeutic effect, along with the development of social medical industry and popularizing of medical knowledge, people are more and more higher to the requirement of syringe, press for a kind of disposable syringe that can carry medicinal liquid.

Summary of the invention:

Invention order of the present utility model be to provide a kind of carry medicinal liquid mould the glass disposable syringe.

Described in the utility model carry medicinal liquid mould the glass disposable syringe, by the glass syringe, plastic push-rod, the silica gel sealing piston, injection medicinal liquid and needle stand medicated cap are formed, the needle stand medicated cap is sleeved on the needle stand of glass syringe hermetically, the silica gel sealing piston is fixed on the front end of plastic push-rod, between silica gel sealing piston and the glass syringe endoporus is interference fit, be that the silica gel sealing piston is sealably twitched in the glass syringe, the injection liquid medicine filling is in the glass syringe, and be in silica gel sealing piston and the formed space of needle stand medicated cap, on the glass syringe, be provided with the scale of indication injection medicinal liquid capacity.

As to improvement of the present utility model, the material of described needle stand medicated cap is a silica gel.

Learn through long term test and analysis, glass and silica gel can not pollute or modification the injection medicinal liquid, therefore this utility model adopts the syringe of glass, the push rod of plastics, the needle stand medicated cap of the packed-piston of silica gel and silica gel form a kind of carry the injection medicinal liquid mould the glass disposable syringe, this syringe is the storage bottle of injection medicinal liquid, it is again the syringe of injection, and the injection amount that prestores in every syringe can be set arbitrarily, can make plurality of specifications according to adult and child's different amounts, during use, as long as extract silica gel needle stand medicated cap, the syringe needle of loading onto through sterilizing just can direct injection, not only easy to use, and can not waste medicinal liquid, need not liquid containing bottle again, thereby not only economical and practical but also quick health.If change syringe into plastics, the medicinal liquid long-term storage will cause medicinal liquid modification or pollution therein; If syringe and push rod all adopt glass, though both can not produce any pollution and modification to the injection medicinal liquid at the material of itself, but owing to be inflexible matched in clearance between syringe and the push rod, its air-tightness is bad, and the injection medicinal liquid leaves in the syringe, and medicinal liquid can infiltrate lentamente on the one hand, Wai Jie gas can pollute medicinal liquid on the other hand, the requirement on machining accuracy of syringe and push rod is all than higher simultaneously, and therefore, existing glass syringe and plastic injector for temporary use all should not carry medicinal liquid.
