Disposable use injection device

This utility model relates to a kind of medical apparatus and instruments, and specifically a kind of preventing reused, and prevents to cause the disposable use injection device of cross infection.

At present, hospital is the cross infection that prevents that the repeated use of syringe from causing, generally adopt the all-plastic disposable syringe, yet also have many scientists still to improve and improve disposable syringe constantly, its cost is reduced, easy to use, be easy to carry, be " safety injector " as No. 88204307.2 name of patent application of Chinese patent; The 90221005.X patent application, name is called " disposable syringe "; No. 93213815.2 patent name all discloses as disposable syringe for " the disposable medical fluid injector of filling " etc., but in structure and use, all exist sealing fungi-proofing not good, complex process, deficiencies such as inconvenience use also fail product is introduced to the market up till now.

The purpose of this utility model provides a kind of simple in structure, and it is fungi-proofing good to seal, and uses disposable use injection device easy to carry.

The purpose of this utility model realizes in the following manner, medicinal liquid is stored among the medicine bag of being made by plastic sheeting, needle body is installed among the needle stand, needle stand and medicine bag fix, needle body is fixed on the needle tubing, the pin medicated cap has all covered the fungi-proofing effect of sealing with needle tubing, forms disposable use injection device, packs with outer package then.

Accompanying drawing 1 is the structural representation of facing of disposable use injection device;

Accompanying drawing 2 is the side-looking structural representation of disposable use injection device.

Explain below with reference to accompanying drawing disposable use injection device of the present utility model being done.

Disposable use injection device of the present utility model be by external packing (1), anther sac (2), Needle stand (4), needle body (5), needle tubing (6), pin cap (7), barrier film (3) Form, needle body (5) is fixed on the needle tubing (6), and needle body (5) is installed in needle stand (4) in, needle stand (4) and anther sac (2) fix, and pin cap (7) covers at needle body (5) upper end. Needle body (5) is fixed on the needle tubing (6), needle tubing (6) two ends All be with point, stretch out from needle body (5) two ends, and the upper end extension be longer than the lower end extension Divide. Needle body (5) is installed together needle body (5) with needle stand (4) for closely cooperating Have the bipassage ring connected in star on the cylindrical at middle part, the inwall of needle stand (4) is provided with ring one Shape boss, annular boss are stuck among the annular groove on the needle body (5). In order to make anther sac (2) the front sealing of the soup in, the bottom in needle stand (4), be provided with one the sealing use every Film (3), the tip of the top and needle tubing (6) of barrier film (3) is mutually close.

Embodiment, disposable use injection device of the present utility model, it is made and uses very simple and conveniently, and it behind the package encapsulation, gives earlier through strict sterilization treatment outside.During use, tear outer package and take out injection device, with hands or take the photograph son and clamp the upper end of needle body and in needle stand, press, annular groove on the needle body is submerged among the needle stand, and be stuck on the annular boss on the needle stand inwall, the medicinal liquid that the needle tubing that this moment, stretched out the needle body lower end is just worn out in seal dissepiment and the medicine bag communicates, and pulls up the just injectable operation of anti-acicula medicated cap, with finger extruding medicine bag, medicinal liquid just can penetrate from needle tubing.Another effect that is exposed at the annular groove of needle stand outside on the needle body is whether the identification injection device was used, and submerging as annular groove illustrates and used that exhausted needle body can not be extracted again among the needle stand.

Disposable use injection device of the present utility model is compared with existing technology has the structure letter Single, reasonable in design, easy to use, cost is low and reduce the characteristics such as drug loss, will be The substitute products of existing disposable syringe have the value of well promoting the use of.
