Description

Three-stage filtration sterile liquid medicine packaging

technical field

The present invention relates to a kind of medical packaging, in particular to a three-stage filter aseptic medical liquid packaging.

Background technique

Existing multi-dose eye drop packaging is a common structure, mainly composed of three parts: bottle body, bottle stopper and bottle cap, wherein the functions of each part are relatively simple. Open the bottle cap, squeeze the bottle body, and the medicinal liquid flows out of the bottle body through the hole in the middle of the bottle stopper, so as to achieve the purpose of administration. Loosen the bottle body, and the air in the normal environment is filled into the bottle body through the hole in the middle of the cork to reset the bottle body. Generally, the medication cycle of multi-dose eye drops for patients is more than seven days, and some even have a longer cycle. When the bottle cap is opened, the packaging system of this structure cannot effectively isolate the liquid medicine from contacting with ordinary ambient air, and the liquid medicine will inevitably be added with preservatives or antibiotics during production to protect the liquid medicine.

In view of the above-mentioned defects of the prior art, it is necessary to design a new three-stage filter aseptic liquid medicine packaging.
