Abstract
The utility model relates to an inverse suction preventing syringe. The inverse suction preventing syringe comprises a needle tube, wherein a medicine outlet is formed at the front end of the needle tube, the front end of the needle tube is closed and fixedly connected with an inverse suction preventing sealing chamber, the inverse suction preventing sealing chamber is in the shape of a hollow and inverted round table, the inverse suction preventing sealing chamber is hermetically communicated with the medicine outlet, a needle head connection port is formed on the front end surface of the inverse suction preventing sealing chamber, a floating plug is arranged in the inverse suction preventing sealing chamber, the floating plug is in the shape of an inverted round table, the diameter of the front end surface of the floating plug is smaller than that of the front end surface of a cavity of the inverse suction preventing sealing chamber, the diameter of the back end surface of the floating plug is larger than that of the back end surface of the cavity of the inverse suction preventing sealing chamber, the inner side of the front end surface of the inverse suction preventing sealing chamber is fixedly connected with a bulge, and bubbles are formed in the floating plug. As both the inverse suction preventing sealing chamber and the floating plug in the inverse suction preventing syringe disclosed by the utility model are shaped like the inverted round tables, when the inverse suction preventing syringe is used for injection for human bodies and animal bodies, a medicine can pass normally, and when the inverse suction preventing syringe is used for extracting other types of medicine liquid after recovery, the floating plug can retreat for sealing the medicine outlet, so that the inverse suction preventing syringe disclosed by the utility model can effectively prevent inverse suction of the medicine liquid and realize safety in use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of anti-suck syringe.
Background technology
At present, for safety and sanitation, the syringe of using to human and animal's injectable drug mostly is disposable product, some lawless people are in order to seek illegal profit, again extract other medicinal liquids after this class syringe is reclaimed, mix the spurious with the genuine to cheat consumer, directly threaten human and animal's safety.
The utility model content
This utility model, for deficiency, provides a kind of safe anti-suck syringe that uses.
The technical scheme that this utility model solves the problems of the technologies described above is as follows:
A kind of anti-suck syringe, comprise syringe, be provided with piston in syringe, the piston back is fixedly connected with push rod, putting back-end is fixedly connected with and pushes away handle, the syringe front end offers medicine outlet, it is characterized in that, the airtight anti-suck shutoff chamber that is fixedly connected with of syringe front end, anti-suck shutoff chamber is hollow, inverted truncated conical shape, anti-suck shutoff chamber communicates with medicine outlet is airtight, the front end face of anti-suck shutoff chamber offers the syringe needle connector, the indoor floating plug that is provided with of anti-suck shutoff, floating plug is inverted truncated conical shape, the front end face diameter of floating plug is less than the front end face diameter of anti-suck shutoff chamber cavity, the rear end face diameter of floating plug is greater than the rear end face diameter of anti-suck shutoff chamber cavity, the front end face inboard of anti-suck shutoff chamber is fixedly connected with projection.Floating plug is interior with bubble.
This utility model has been set up anti-suck shutoff chamber at the syringe front end, and the indoor floating plug that is provided with of anti-suck shutoff, because anti-suck shutoff chamber and floating plug are all inverted truncated conical shape, therefore when giving human body and animal body injection, medicine can normally pass through, if while after reclaiming, extracting other medicinal liquids, floating plug can retreat, by the medicine outlet shutoff, so this utility model can effectively prevent the suck-back medicinal liquid, use safety.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
