Embodiment Construction

[0014] The method of the invention can be used to prepack and seal syringes on general filling lines. In the specific implementation, first use the needle sealing sleeve to seal the needle end, and place the needle tube body sleeve that has completed the needle end sealing in the body holder, so that it can be pre-filled with medicine on the assembly line like a vial, after the filling is completed It is sealed by the thin tube plugging method of the exhaust needle (the advantage of the plugging method of the thin tube of the exhaust needle is that it does not require the elasticity of the plug rubber, and the plug rubber does not produce wrinkles, etc.), so far the pre-installation sealing stage is completed. In summary, the syringe prepacking and sealing method of the present invention is economical, practical and reliable, and has the characteristics of being easy to implement for improving product quality and upgrading.

Abstract

The present invention provides a preassemble sealing method for an injector, which adopts a pinhead sealing sleeve to seal the pinhead; the syringe body which finishes the pinhead sealing is sleeved with a body supporting sleeve so as to realize vertical fill sealing on the pipeline like the penicillin bottle; after the injector is filled with medicine, a piston as the sealing plug undergoes the injection piston of a corker through an exhaust method of the syringe, thus completing the sealing. The present invention is economic and reliable as well as easy to construct according with the developing trend of the package of the injection medicine.

Description

technical field [0001] The method of the invention relates to medicine packaging, in particular to a method for prepacking and sealing a syringe. Background technique [0002] At present, using syringes to directly package injection medicines, this packaging form is not only about making the best use of everything, but also derives many advantages in use and is adopted by the pharmaceutical industry, which is forming a development trend of injection medicine packaging. However, due to the constraints of many factors in terms of production, technology, cost, and use, this packaging form has not been popularized. Contents of the invention [0003] The method of the present invention is designed in response to the aforementioned constraints. [0004] Syringe tip seal [0005] A syringe generally consists of a needle cover, an injection needle, a needle body, a piston and a push handle. The prefilled drug must first seal the needle end of the syringe. The present invention...
