Abstract
The utility model discloses a secondary-infection-preventing needle dropper which comprises a needle cylinder. A cylinder boss is arranged at the top of the needle cylinder, a piercing steel needle is embedded into the middle of the cylinder boss, an annular groove is formed in the cylinder boss of the needle cylinder, and an isolating protection device is arranged on the cylinder boss and is formed by sequentially connecting an upper top cover, a middle elastic rubber barrel and a lower fixing barrel. The top of the upper top cover is flush with the top of the piercing steel needle, and the lower fixing barrel is inserted into the annular groove. The secondary-infection-preventing needle dropper adopts the isolating protection device having certain extension capacity, so that the needle dropper is prevented from directly exposing in the air in the operation process of the piercing steel needle, and the piercing steel needle can be always and basically in a certain sealed environment in the process from package unwrapping to final usage. The secondary-infection-preventing needle dropper can avoid medical negligence caused by secondary infection of the piercing steel needle to the most extent, and the using safety of the needle dropper is improved.
Description
Technical field
This utility model relates to a kind of superinfection type pin dropper of avoiding.
Background technology
In the technique known field, in daily medical procedure, the pin dropper is a kind of common medical treatment consumptive materials, general being used for infuses, blood transfusion, hybrid medicine solvent etc. relates in the operation of liquid, in the use of reality, when pin dropper in case remove from disposable packing comes, the draw point that pierces through at its top just is exposed in the air, extracting blood, in the operating procedure of liquid such as hybrid medicine, easily because outside air, object, saliva, the contact of dust etc., cause secondary pollution, if improper when operation, piercing through draw point will directly contact with infectious agent, and very possible people also do not find, cause potential safety hazard, the malpractice of superinfection takes place easily.
The utility model content
The technical problems to be solved in the utility model is: a kind of pin dropper of avoiding piercing through draw point generation superinfection malpractice is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of superinfection type pin dropper of avoiding; comprise syringe; the top of described syringe has the cylinder boss; pierce through draw point in the embedding of the middle part of described cylinder boss; cylinder boss at described syringe is provided with annular groove; be provided with isolated protector at described cylinder boss; described isolated protector is by upper top cover; middle caoutchouc elasticity tube and following stationary magazine creel connect and compose in turn; the top of described upper top cover is concordant with the top of piercing through draw point, and described stationary magazine creel down is inserted in the annular groove.
Further, aerofluxus for convenience makes isolated protector can obtain smoothly using, and the sidewall of the following stationary magazine creel of this utility model on described isolated protector offers passage.
Further, for the liquid that draw point flows out is pierced through in sealing better, this utility model on the described outer wall that pierces through draw point and the internal sleeve that is positioned at isolated protector be provided with the rubber seal tube.
The beneficial effects of the utility model are: this utility model is set up the isolated protector with certain flexible ability by employing; avoid piercing through draw point and in the process of operation, be directly exposed to airborne situation; can make that piercing through draw point removes in the process of the last use of coming from packing; it can be in certain sealed environment all the time substantially; this programme can avoid piercing through the malpractice of draw point generation superinfection to greatest extent, has improved the usage safety performance of pin dropper.
