Abstract

The utility model discloses a disposal injector, which comprises an injection tube, a medicine bottle, a syringe needle, a needle cap and a pressure plate, wherein a double-syringe needle injection needle with an inner syringe needle and an outer syringe needle is mounted on the front end of the injection tube, a groove where the thumb of an injector can back and forth slide is longitudinally arranged on one side of the injection tube, and the medicine bottle is an elastic and telescopic plastic bag, the pressure plate is fixed on the rear end of the medicine bottle, a restoring spring is arranged between the pressure plate and the lower end of a sliding groove, when in use, the inner syringe needle is penetrated into the front end of the medicine bottle, the outer syringe needle is inserted into injection after pressing the pressure plate, and since the restoring spring is arranged between the pressure plate and the sliding groove, injection can be absorbed in the medicine bottle rapidly by means of the spring, and the pollution of particles and microbes in air to medicine solution can be lowered since medicine solution is extracted in shorter time, and meanwhile, operation pollution is reduced. The disposal injector saves time and labor, which has high security.

Description

Disposable syringe

Technical field

This utility model belongs to medical instruments field, relates in particular to a kind of low pollution syringe easy to use.

Background technology

Existing injection generally is contained in the vial, must earlier vial be broken into pieces during use, and then with in the injection inhalation syringe, medicine needs to transfer in the syringe and could inject from the storage medicine.Syringe is to use the push-and-pull syringe mostly, this syringe substantially all is to be made of injection tube and the handle and the syringe needle that are installed in the injection tube, bottle breaks glass during use, syringe needle is inserted the medicinal liquid bottle, extract medicinal liquid, in extracting the process of medicinal liquid, sometimes in addition need hands of medical personnel fixedly syringe another hands pull handle medicinal liquid could be extracted, have following shortcoming: the one, extraction medicinal liquid time length, troublesome poeration, waste time and energy; The 2nd, poor stability, in the process of making up a prescription, medicament is exposed in the air fully, very easily causes microgranule, microorganism pollution and the operational pollution to medicinal liquid.

Summary of the invention

The purpose of this utility model provides a kind of low pollution disposable syringe easy to use, has simple to operate, safety.

The purpose of this utility model is achieved through the following technical solutions:

A kind of disposable syringe, comprise injection tube, drug holding bottle, syringe needle, pin medicated cap, pressing plate, described injection tube front end is equipped with a double needle entry needle that inside and outside syringe needle is arranged, one side of described injection tube vertically has the groove that the thumb that can make the injector slidably reciprocates, the plastic bag that described drug holding bottle is rubber-like, can stretch, a pressing plate is fixed in described drug holding bottle rear end, is provided with back-moving spring between pressing plate and sliding channel lower end, and interior syringe needle thrusts the drug holding bottle front end during use.

Above-mentioned disposable syringe, the injection tube front end also is provided with needle cap, and needle cap is buckled on the outer syringe needle.

Above-mentioned disposable syringe, a boss is established in described sliding channel lower end, and the pressing plate of the position corresponding with groove is provided with clamp, and clamp is the part that pressing plate stretches out, and back-moving spring is fixed between clamp and boss.

Above-mentioned disposable syringe also is provided with handle on injection tube.

The beneficial effects of the utility model are: syringe needle thrusts the drug holding bottle front end in during use, after pushing pressing plate outer syringe needle is inserted in the injection, owing between pressing plate and sliding channel lower end, be provided with back-moving spring, effect by spring can be drawn to injection in the drug holding bottle rapidly, extract medicinal liquid like this within a short period of time and reduced the pollution of microgranule in the air, microorganism medicinal liquid, reduce operational pollution simultaneously, this utility model working costs effort has very high safety.
