[0028] In one embodiment, Figure 5 As shown, the storage bag 101 includes a stem cell storage bag 106 and a cryopreservation liquid storage bag 107. For convenient storage, the cryopreservation liquid storage bag 107 is installed on the side of the stem cell storage bag 106, so that the stem cells can be stored quickly and can be stored for a certain period of time without being refrigerated.

[0029] In one embodiment, Figure 1 and Figure 4 As shown, the infusion mechanism 2 includes a delivery hose 201 and a cryopreservation liquid infusion tube 203. A speed regulating head 202 is slidably provided on the surface of the delivery hose 201. The end of the delivery hose 201 passes through the storage bag 101 and is fixedly connected to the stem cell storage bag 106. The cryopreservation liquid infusion tube 203 passes through the storage bag 101 and is fixedly connected to the cryopreservation liquid storage bag 107. Stem cells can be input and output from the stem cell storage bag 106 through the delivery hose 201. The speed regulating head changes the degree of compression of the delivery hose 201 by adjusting the position of the wheel, thereby adjusting the flow rate. The cryopreservation liquid can be input and output to the cryopreservation liquid storage bag 107 through the cryopreservation liquid infusion tube 203.

[0030] In one embodiment, Figure 2 and Figure 3 As shown, the sampling mechanism 3 includes a sample bag 303, the lower surface of the sample bag 303 is fixedly connected to the seal 301, the seal 301 is fixedly connected to the stem cell storage bag 106 in the storage bag 101, and the upper surface of the sample bag 303 is fixedly connected to the sampling tube 302.
