Description
Technical field
The present invention relates to disposable syringe technical fields, and the present invention relates to disposable family of four syringes.
Background technique
Disposable syringe is exactly one-shot injector, is to be divided to three-member type and two using made of macromolecule polypropylene material
Part formula, three-piece construction are core bar, rubber plug, three, housing and injection needle, outer packing composition, and two-part construction is core bar, housing
And injection needle, outer packing composition.
However the core bar on existing disposable syringe is directly to contact with outer piston in use
, so that core bar is poor with the isolation of medical fluid in use, often because adhering to medical fluid on core bar core bar can be scrapped,
It can not be reused, greatly waste material, and also lack seal member on existing disposable syringe
Design so that nurse is after exhausting medical fluid with syringe, due to other things to handle cannot liquid medicine injection immediately when, Chang Hui
Because medical fluid sealing is unreliable medical fluid is outflowed, pollutes station, it is more dirty and messy in turn result in syringe use environment, therefore
It is badly in need of disposable family of four syringe to solve existing issue.
