Nowadays, there are many types of infusion devices on the market, and the quality is different. So how can we choose the most suitable infusion device scientifically? Then we first need to know the following three points.

First of all, the current priming devices are mainly made of glass and plastic materials. Plastic priming devices are gradually replacing glass prefilled syringes. They are mainly of lower cost, higher safety than glass syringes, not easy to break, and better quality. The production technology of the infusion device of the company is relatively advanced. Generally speaking, the injection molding process is used to produce the infusion device. The products produced by the injection molding process are molded at one time, with no leftovers, accurate product size and uniform weight.

Second, the sealability requirements of the infusion device are relatively high. When selecting the infusion device, the sealability should be tested. Inject half of the water into the infusion device, insert the plunger into the syringe, remove the protective cap, and remove the remaining air. Block with a protective cap, apply an axial pressure of 30N on the push rod rubber plug inside the syringe through the push rod, and keep it for 30 seconds. There should be no leakage at the sealing part of the protective cap and the piston seal.

Third, because the infusion device is in direct contact with the drug, its sterility must be guaranteed. Generally, the infusion device should be produced in a clean workshop that meets the national standards. In addition, in order to ensure its sterility, if the pharmaceutical manufacturer has high sterility Upon request, additional ethylene oxide sterilization or cobalt 60 irradiation sterilization can be performed.
