As a new type of medicine packaging, injection medicine packaging has the characteristics of simple use and convenient operation. The use greatly reduces the process of dispensing before the use of medicines; it reduces the error of medicine dosage, because the pre-filling of injection medicine packaging contains It is a brand-new device that combines the primary packaging of liquid preparations and syringes as a whole with absolute precise dosage for injection.
The pre-filled syringes for injection medicine packaging are mainly composed of a needle tube, a rubber piston, a push rod, a cone head and a protective cap. The syringe assembly has good compatibility with the medicine, and the syringe itself has a good sealing performance, and the medicine can be stored for a long time. The sealing of the pre-filling of injection drug packaging is mainly controlled by the following points:
First, the use of sealing members 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 a timely manner, and if necessary, the integrity of the seal should be verified again;
Third, the verification of the tightness requirements should meet the requirements of bacterial intrusion test and saturated brine test;
Fourth, in addition to the conventional experimental methods, pre-filled syringes should also be tested for influencing factors, accelerated experiments, etc. to ensure that the sealing performance within the effective period meets user requirements.
