Description

A kind of powder-injection prefilled syringe mixing arrangement

Technical field

The present utility model belongs to the field of medical instrument technology, is related to a kind of prefilled syringe mixing arrangement.

Background technique

It is a kind of for mixing powder and the syringe premounting mixing arrangement of solvent, be related to syringe, solvent container, pulvis and hold Device, sterilizing equipment decontaminating apparatus etc. are mainly used for solving folding neck ampoule, clamped bottle bring needle in existing powder needle agent configuration process and stab, is sharp Device injures problem easy to pollute, simplifies operation link；It includes prepackage pulvis syringe, syringe needle, shield needle cap, easily broken formula pull ring, molten Matchmaker's container totally 5 parts.

Summary of the invention

The purpose of the present utility model is to provide a kind of powder-injection prepackage mixing arrangement, solves clinical use powder-injection Cumbersome operation link in the process avoids needle from stabbing and pollution problem.

What technical solution used by the present utility model above-mentioned technical problem to be solved was realized in：Mainly By：Piston, syringe, syringe cream, syringe needle syringe attachment device, syringe needle, shield needle cap, leather plug fixed device, leather plug, pull ring, drawing Item and solvent container are constituted, and piston bush links together in the inside of syringe, nipple and syringe, and syringe needle syringe attachment device covers Outside syringe nipple, syringe needle is connected with syringe needle syringe attachment device, and the inclined-plane of syringe needle is located inside leather plug, and shield needle cap is two The hollow cylinder of different-diameter is constituted, and the small end cap of diameter is in the outside of syringe needle syringe attachment device, the big one end of diameter It covers in the outside of the fixed device of solvent container leather plug, the fixed device of solvent container leather plug is covered outside the oral area of solvent container and wrapped Wrap up in leather plug, leather plug is covered in solvent container finish inner face, and the fixed device of leather plug is wrapped up in outside, pull ring by tie rod connection shield needle cap with Solvent container, thin and easily openable, solvent container are connected by leather plug with syringe needle.The shield needle cap is the different sky of two diameters The heart is cylindrical, and function is the length for protecting the needle tip of syringe needle and limitation syringe needle to enter solvent container.The solvent container is Two kinds, one is the small dimension containers for locally injecting, and one is the big size containers for venous transfusion, can be according to difference It needs to configure.

The powder for injecta emitter mixing arrangement of the utility model mainly by：Pre-install powder for injecta emitter, syringe needle, shield needle cap, Easily broken formula pull ring, solvent container are constituted.It is divided into two kinds, a kind of to use syringe to carry out the device of locally injecting, one kind is to make With the device of prepackage solvent container connection infusion apparatus.In shape, construction and combine upper, the powder-injection prepackage mixing of the utility model The essential features of device are：The pulvis of prepackage powder-injection in syringe；Pinpoint inclined plane part fully penetrates solvent vessel head The leather plug in portion but do not penetrate leather plug, it is therefore an objective to keep syringe to be in air-tight state, syringe piston will not be moved arbitrarily, internal Filled pulvis will not be mixed because of the external forces such as transport leakage or with solvent；It is shield needle cap outside syringe needle, it is straight by two differences The hollow cylinder of diameter forms, and the hollow cylinder of two different-diameters forms step shape, and the small end cap of diameter is in syringe needle syringe At attachment device, the big end cap of diameter is outside the head of solvent container；It is needed with the part that solvent vessel head is nested together A pull ring is wanted, pull ring is connected with tie rod, tie rod both sides and shield needle cap and solvent container connection section is thin and easily openable, is used When, it pulls pull ring to tear the coupling part of tie rod, to protect needle cap and the disconnection of solvent container, protects needle cap and syringe needle is total Solvent container part in the same direction promotes, so that syringe needle pierces through leather plug completely, makes to pass through syringe needle inside syringe and inside solvent container It communicates, mixes pulvis and solvent；After syringe needle pierces through leather plug completely, the small circle of the step agent diameter that two hollow cylinders are formed It is touched at the top of column and solvent container leather plug, hinders syringe needle to move ahead, the needle tip of syringe needle is made to remain in the most bottom of solvent container Portion；Requirement of the solvent container to leather plug is thickness more than 2-4 millimeters of syringe needle point chamfer length, and pinpoint inclined plane is pierced into leather plug Afterwards, front and back respectively retains 1-2 millimeters, and function is that pinpoint inclined plane part submerges leather plug completely but do not penetrate leather plug, so that syringe is protected Hold airtightness；Tie rod and shield needle cap effect are fixed solvent container and syringe needle and syringe, are that three is made to be in stationary state （Position is kept fixed from each other）, when use pulls off pull ring, and tie rod is torn, and syringe needle can be promoted or be exited；Solvent Container is two kinds of designs：One kind being used for locally injecting, and solvent container is the lesser ampoule of capacity, and mixing finishes when use, removes Shield needle cap can be injected, and another kind is used for venous transfusion, and solvent container is the biggish infusion bag of capacity（Or bottle）, when use Shield needle cap and syringe needle are removed from leather plug together can connect infusion apparatus.

The beneficial effect of utility model powder-injection prefilled syringe mixing arrangement：The utility model powder-injection prepackage mixing dress Setting is linked together syringe and solvent container, and whole device keeps closed, and avoiding causes in traditional powder-injection configuration process Pollution, the problems such as needle is stabbed and sharp weapon are hurt reduces operation link, medical worker facilitated to operate.
