The utility model discloses a vacuum sampling suite for a
stem cell bagged preparation, which belongs to the technical field of
cell collection and comprises a vacuum negative pressure tube and a
catheter component, a
bottle plug is arranged at a tube opening of the vacuum negative pressure tube, and scales are arranged on a tube body of the vacuum negative pressure tube; the
catheter assembly comprises a three-way connector, a pipetting
catheter and a sampling catheter, the three-way connector is communicated with the
stem cell preparation
cryopreservation bag through a sampling needle, one end of the pipetting catheter is connected with the three-way connector, the other end of the pipetting catheter is used in cooperation with a pipettor through a suction head, and one end of the sampling catheter is connected with the three-way connector. And the other end of the sampling catheter is provided with a puncture needle connected with a vacuum negative pressure tube. The
combined use of the pipetting catheter, the pipettor, the vacuum negative pressure tube and the sampling catheter is adopted, normal
saline with a definite volume can be injected into the bag to dilute
cell sap, then negative pressure is used for extraction, the
cell sap can be prevented from remaining in the bag, and the operation is simple and easy to control.
