Abstract
The utility model relates to a novel needle cap, which belongs to the field of medical appliances, in particular relates to an improvement of an injector needle cap. The front end of the needle cap is in interference fit and connection with an air filter main body, a filter membrane is arranged in the air filter main body, a filter membrane gland bush is connected with the filter membrane in a pressing way, and the filter membrane gland bush is in interference fit and connection with the air filter main body. The utility model has the advantages that the structure is novel, the needle cap is simple and practical, and when an injector performs the air exhaustion operation, an air filter connected with the needle cap purifies the air, thereby particularly being suitable for a hospital ward or a family without the air purifying condition, providing convenience for the dispensing operation of medical personnel and being easy to generalize.
Description
Technical field
This utility model belongs to medical instruments field, refers in particular to the improvement to the syringe needle medicated cap.
Background technology
Conventional injector syringe needle outside when dispatching from the factory is with the pin medicated cap; this pin medicated cap plays a protective role to syringe needle; during use; the pin medicated cap is removed; when will in the medicine bottle of evacuation, injecting air,, in clean environment, extract air in certain amount with syringe earlier usually so that when carrying out feeding operations; or in clean work station, carry out, could guarantee to be drawn into like this to purify air.But the equipment that air is not purified in the ward of present many hospitals needs to carry out in special clean work station, and is so just very inconvenient; As when needs are operated in family, more can not guarantee in clean environment, to have operated.
Summary of the invention
This utility model provides a kind of novel pin medicated cap, is not having under the condition of air cleaning facility to solve, and syringe can not be drawn into the problem of clean air.The technical scheme that this utility model is taked is: pin medicated cap front end interference fit connects the air filter main body, and filter membrane is positioned at this air filter body interior, filter membrane gland and filter membrane crimping, and this filter membrane gland is connected with air filter main body interference fit.
A kind of embodiment of this utility model is that air filter body front end and pin medicated cap junction are with small casing.
During use, syringe is connected with syringe needle, when extracting air, air filter can purify air, and the air that the syringe suction has been purified will remove the pin medicated cap afterwards, carries out next step operation.
This utility model advantage is novel structure, and is simple and practical, when the air filter that is connected with the pin medicated cap is bled operation at syringe, air purified.Be particularly suitable for not having the hospital ward or the family of air cleaning condition to use, provide convenience to medical personnel's dispensing operation, and be easy to promote.
