Abstract
This utility model discloses a liquid extractor, belonging to the field of cell preparation technology, comprising: a needle, a liquid guide tube, and an exhaust tube. The needle has an inlet hole at its head and is used to penetrate into a liquid storage container. The needle also has an outlet hole and an exhaust hole communicating with the inlet hole. The liquid storage container is located above the needle. The liquid guide tube communicates with the outlet hole, and the end of the liquid guide tube away from the needle is adapted to selectively connect to a plug or a cell preparation device. The exhaust tube communicates with the exhaust hole. According to this utility model, the liquid extractor can be used to continuously inject physiological saline into a cell preparation device and can prevent physiological saline leakage.
