As a new type of medical packaging method, the medical packaging syringe has the characteristics of simple use and convenient operation. The use greatly reduces the process of dispensing before the drug is used; it reduces the error of the drug dosage, because the medical packaging contains all precise absolutes. Medication dosage, it is a brand-new device that combines the primary packaging of liquid preparations and syringes into one.


The medical packaging syringe is mainly composed of a needle tube, a rubber piston, a push rod, a cone and a protective cap. The syringe components have good compatibility with drugs. At the same time, the syringe itself has good sealing performance, and the drugs can be stored for a long time. The tightness of medical packaging syringes is mainly controlled by the following points:


First, adopt sealing components that comply with internationally accepted standards;


Second, when the components of the sealing system or the potting system are changed, the impact on the sealing system should be evaluated in time, and the sealing integrity should be re-verified if necessary;


Third, the verification of tightness requirements should meet the requirements of bacteria intrusion test and saturated salt water test;


Fourth, in addition to the conventional experimental methods for medical packaging syringes, influencing factor experiments and accelerated experiments should also be conducted to ensure that the sealing performance during the validity period meets user requirements.
