Abstract
本实用新型公开了一种一次性注射器，包括注射筒、盛药瓶、针头、针帽、压板，所述的注射筒前端装有一个有内、外针头的双针头注射针，所述注射筒的一侧纵向开有可以使注射者的大拇指来回滑动的沟槽，所述盛药瓶为具有弹性的、可以伸缩的塑料袋，所述盛药瓶后端固定一压板，在压板与滑动沟槽下端间设置有复位弹簧，使用时内针头刺入盛药瓶前端，使用时内针头刺入盛药瓶前端，按压压板后将外针头插入注射液中，由于在压板与滑动沟槽下端间设置有复位弹簧，靠弹簧的作用可以迅速将注射液吸取到盛药瓶内，这样在较短时间内抽取药液降低了空气中微粒、微生物对药液的污染，同时减少操作污染，本实用新型使用费时费力，有很高的安全性。
The utility model discloses a disposable syringe, which comprises a syringe, a medicine bottle, a needle, a needle cap and a pressing plate. A double-needle injection needle with inner and outer needles is installed at the front end of the syringe. There is a longitudinal groove on one side of the side that allows the thumb of the injector to slide back and forth. The drug-containing bottle is an elastic and stretchable plastic bag. A pressing plate is fixed at the rear end of the drug-containing bottle. There is a return spring between the lower ends of the grooves. When in use, the inner needle penetrates into the front end of the medicine bottle, and when in use, the inner needle penetrates into the front end of the medicine bottle. After pressing the pressure plate, the outer needle is inserted into the injection solution. There is a return spring in between, and the injection liquid can be quickly sucked into the medicine bottle by the action of the spring, so that the medicine liquid can be extracted in a short time to reduce the pollution of the air particles and microorganisms to the medicine liquid, and at the same time reduce the operation pollution. The use of the utility model is time-consuming and labor-intensive, and has high safety.
Description
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.
