Description

A kind of clip type bottled syringe

Technical field

This utility model belongs to technical field of medical instruments, relates to a kind of clip type bottled syringe.

Background technology

When carrying out intravenous injection or the treatment of intramuscular injection medicine to the patient clinically, the overwhelming majority adopts disposable syringe to draw Pharmaceutical from ampoule or cillin bottle to inject at present, there is following deficiency in this operation: cause liquid waste or finger injuries when breaking into two with one's hands or break ampoule easily, the cullet bits also might bring unnecessary damages to the patient; Medicinal liquid contacts with air, causes secondary pollution easily; Concerning some has very supervirulent medicine, can affect greatly environment, again to medical personnel's the bigger harm of healthy existence; Each dosing all will be used a disposable syringe, and large usage quantity can increase financial burden to the patient.Repeatedly used clip type bottled syringe has also appearred in the shortcoming at this traditional clinically drug administration by injection exists on the market, but because its structural design is unreasonable, is not easy to processing and manufacturing, and the production cost height has restricted promoting the use of of clip type bottled syringe.

Summary of the invention

The purpose of this utility model provides a kind of clip type bottled syringe, and having solved existing clip type bottled syringe can not reuse, the problem that production cost is high.

The technical scheme that this utility model adopted is, a kind of clip type bottled syringe, it is characterized in that: comprise pusher bar support and casing, the termination of pusher bar support has the push rod mouth, one push rod is arranged in the pusher bar support and from the push rod mouth, pass, the other end of push rod is connected with the piston of cassette bottle, the installation limit of pusher bar support is provided with fixedly lug and bayonet socket, the correspondence of casing is installed the limit and is provided with fixed rotating shaft and bayonet socket bearing pin, fixedly lug is connected with fixed rotating shaft, bayonet socket is connected with the bayonet socket bearing pin, and the termination of casing has the syringe needle mouth.

Feature of the present utility model also is:

Push rod is equipped with handle from the end that the push rod mouth passes.

Be with guide cylinder in the pusher bar support, push rod is installed in the guide cylinder.

Have watch window on the sidewall of casing.

The beneficial effects of the utility model are to reuse, and can not bring disease to propagate mutually, have saved the injection cost.Of the present utility model being also advantageous in that, injection member directly do not contact human body, and reliability of products, safety are higher, are convenient to die sinking manufacturing processing, and production cost obviously reduces.
