A device for aseptic dispensing of cell suspensions from culture bags

Abstract

The technical problem this invention aims to solve is to provide a device for aseptic bagging of cell suspension in culture bags. This device effectively avoids cell suspension exposure and reduces the risk of contamination. The device includes a reagent bottle and a feeding bottle cap. A dispensing tube is installed on the feeding bottle cap. The lower end of the dispensing tube is connected to a sampling tube, a sampling head, and a shunt tube via a first Y-shaped connecting fitting. The lower end of the shunt tube is connected to a first shunt branch and a second shunt branch via a second Y-shaped connecting fitting. A third clamp structure is installed on the first shunt branch, and a fourth clamp structure is installed on the second shunt branch. A cell culture bag or a venting tube is connected to the lower end of the first and second shunt branch via a connector. An air filter is installed at the lower end of the venting tube. An air inlet component is also installed on the feeding bottle cap. This device ensures that the cell suspension is not exposed during the entire operation, effectively reducing the risk of contamination during the bagging process.
