the existing stem cell cryopreserving device supports a test tube for storing stem cells through a support, liquid nitrogen is conveyed into the box body, the temperature inside the device is guaranteed to be suitable for long-time cryopreserving with the stem cells, however, because the storage condition of the stem cells is harsh, the test tube cannot be guaranteed to be used completely in the test tube immediately after being taken out of the device when the stem cells are needed, the temperature of the test tube is fast close to the room temperature after the test tube leaves the device, the residual stem cells in the test tube are easy to deteriorate and damage, and larger use loss is caused.

In order to solve the problems in the prior art, the utility model provides a stem cell cryopreserving device which comprises a storage box, wherein a baffle plate is arranged inside the storage box, a heat preservation pipe is inserted on the surface of the baffle plate, a bracket is arranged at the top of the inner wall of the heat preservation pipe, a test tube is arranged on the inner wall of the bracket, and a colloidal refrigerant is filled between the test tube and the heat preservation pipe.

Preferably, a cavity is reserved between the partition plate and the inner wall of the storage box, liquid nitrogen is filled in the cavity, and the liquid nitrogen is directly contacted with the heat preservation pipe.

Preferably, a cavity is reserved between the test tube and the inner wall of the heat preservation tube, and colloidal refrigerant is filled in the cavity.

Preferably, the heat preservation pipe is made of copper metal, and the surface of the heat preservation pipe is covered with a protective rubber sleeve.

Preferably, the top of the storage box is connected with a sealing cover through a hinge, and sealing gaskets are arranged at the bottom of the sealing cover and the top of the storage box.

Preferably, the cross section of the bracket is L-shaped, threads are arranged on the surface of the vertical direction of the bracket, and a thread groove matched with the threads is formed in the top of the inner wall of the heat preservation pipe.

Preferably, the top of the test tube is in threaded connection with a sealing cover.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the temperature of liquid nitrogen is transferred into the colloidal refrigerant through the heat preservation pipe to enable the colloidal refrigerant to be condensed and to be transferred into the test tube, when the test tube and the heat preservation pipe are taken out of the storage box, the colloidal refrigerant can continuously ensure that the temperature in the test tube is not influenced by the outside in a certain time.
