Abstract

The invention discloses gas-liquid flow dividing sterile drug liquid packaging. The packaging comprises a self-resetting bottle body and a combined bottle plug system installed on the self-resetting bottle body, the self-resetting bottle body is used for containing sterile drug liquid, and the combined bottle plug system comprises a buckle bottle plug shell body used for making the self-resettingbottle body fixedly installed; a filter device is provided with a drug liquid passage and an air filter passage, an air passage inlet communicated with the air filter passage is formed in the buckle bottle plug shell body, a drug liquid passage one-way valve is installed inside the drug liquid passage of the filter device, and the drug liquid passage one-way valve is used for controlling the sterile drug liquid to be sprayed from the self-resetting bottle body to the outside and cannot suck from the outside. The arranged filter passage solves the problem of the contact between the drug liquidinside a packaging system and the general ambient air, and the air entering into the packaging system reaches a sterile grade.

Description

technical field [0001] The present invention relates to a medical packaging, in particular to a gas-liquid diversion aseptic medical liquid packaging. Background technique [0002] 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 ...
