Abstract
The utility model relates to an improved injector for pre-filling liquid medicines, which belongs to clinical medical apparatus. The injector comprises a syringe needle, a syringe and a push rod, wherein the syringe is an integral glass syringe, the syringe needle is fixedly inserted in a conical body on the front end of the glass syringe, the needle hole of the syringe needle is communicated with the inner cavity of the glass syringe, a syringe needle sealing cap is assembled on the syringe needle, a medical rubber piston for is assembled in the inner cavity of the glass syringe, the piston is connected with the push rod by screw threads, and the turned-over edge of the bottom end of the glass syringe is provided with double trimmed edges. The injector has reasonable structure and convenient usage, is safe and reliable, can be directly used for holding the liquid medicines,, increases the usage rate of the liquid medicines, reduces the waste of the liquid medicines and the use cost, is convenient for destroy and management after one-off use, avoids the reusage and reduces the pollution. The utility model simplifies the intermediate links from factory leaving to body injection, provides safer and more reliable use of injection medicines for people and has prominent economic and social benefits.
Description
Technical field
This utility model relates to a kind of improved syringe, belongs to the clinical treatment utensil.
Background technology
All-glass syringe and plastic injector for temporary use have been experienced in the development of syringe, and being connected of its needle tubing conehead and syringe needle all is to lean on the needle stand of metal and plastics to finish.This class syringe can not store medicinal liquid for a long time, and therefore, in use, the topping up that need make up a prescription is immediately injected.On the one hand, medicinal liquid is by other packaged media, and then shifts and use, and transfer potential necessity of medicinal liquid causes residual waste, and especially to few costly medicine of use amount and biologics etc., this problem is more outstanding; On the other hand, there are serious problems in the destruction and the use and management of such syringe, and reusable problem is difficult to be solved, and is seriously polluted, and hazardness is big.
Summary of the invention
The purpose of this utility model is to provide a kind of improved pre-filled medicinal liquid injector, and is rational in infrastructure, safe and reliable, directly the splendid attire medicinal liquid, easy to use, improve the medicinal liquid utilization rate, reduce liquid waste, destruction and management after being convenient to once use are avoided reusing, and reduce and pollute.
Pre-filled medicinal liquid injector described in the utility model, comprise syringe needle, syringe and push rod, glass syringe bottom is provided with flange, its syringe is the integrated glass syringe, and plug-in mounting is fixed with syringe needle on the cone of glass syringe front end, and the syringe needle pin hole communicates with the glass needle tube inner chamber, be fitted with the syringe needle sealing cap on the syringe needle, the glass needle tube inner chamber is fitted with the medical grade rubber piston, is threaded between piston and push rod, and glass syringe bottom flange is provided with two the side cut.
Establish the step hole clipping on cone, syringe needle is inserted on the hole clipping, is convenient to operation, and is safe and reliable.
The glass syringe is convenient to the permanent storage of medicinal liquid, and cone is connected simple and reliable with syringe needle, and globality is strong, during use, directly screws the installation push rod, can carry out injection operation, and the topping up that needn't make up a prescription is convenient and strength-saving; There is not the medicinal liquid branch problem, avoided the residual waste of medicinal liquid, improved the utilization rate of medicinal liquid, reduced the waste of medicinal liquid; The glass syringe is thoroughly destroyed easily, and the use of pre-filled medicinal liquid injector is effectively controlled in the pharmaceutical factory, has fundamentally stopped the repeated use problem to syringe, avoids cross-contamination, and is safe and reliable.The rolling of glass syringe has been avoided in two side cuts, and steadiness is good.
This utility model is rational in infrastructure, and is safe and reliable, and directly the splendid attire medicinal liquid is easy to use, improved the medicinal liquid utilization rate, reduced liquid waste, reduced use cost, and repeated use has been avoided in destruction and management after being convenient to once use, has reduced pollution.Use this utility model to simplify medicine and come out to intermediate link, make people use the injection medicine more safe and reliable, economic benefit and obvious social benefit to the human injection from producer.
