The air admission hole of sealed container interior is contained in during individual sealing container, the other end of sleeve is provided with and for air admission hole to enter into sealing appearance
The gas in device gas transport chamber is discharged into the venthole in the external world, and the needle body below sleeve is set to fluid injection zone, fluid injection
The side in area offers fluid injecting hole.
Further, described needle cylinder surface seamless connection needle stand, the hollow cavity linking needle stand inside at the top of needle body is run through
Syringe interface, the hollow structure between the syringe interface that the inner chamber of needle body and needle stand run through is set to fluid transmission cavity.
Further, the shape of described needle point is in cone.
Further, described fluid injecting hole is arranged at the side of needle body, the distance of fluid ostium to needle point bottom and
The distance of fluid ostium top to sleeve bottom is equal.
Further, described sleeve and fluid injection zone are set to the fillet for seamlessly transitting.
Further, the material that described needle body and sleeve are used uses austenitic stainless steel.
Further, the material that described needle stand is used is sterilized reusable stainless steel in practical operation.
Further, the material that described needle stand is used is transparent plastic cement, and installation flank that the surface of needle stand opens up connects
Entrance.
Further, the material that described needle stand is used is conventional circular hole plug.
Further, described fluid injecting hole and needle point are to avoid the distance between drug waste from being less than 1mm.
The beneficial effects of the invention are as follows：Simple structure, it is practical, it is transferred to another from a sealing container in fluid
Gas during sealing container in sealing container can conveniently be discharged to the external world, while convenient injection mixing, also make in sealing container
Medicine do not infected by virus, it is novel in design beneficial to pharmacists, the operation of doctor, be a kind of good innovation scheme, very
There is market promotion prospect.
