Medical stem cell thawing apparatus

Abstract

The invention relates to the technical field of medical instruments, in particular to a medical stem cell thawing apparatus. The invention mainly aims to solve technical problems in improving the heatexchange efficiency between a stem cell collection bag and water both located in a box. The medical stem cell thawing apparatus comprises a stem cell collecting bag, a box body, partition plates, a circulating pump, a heating device and a clamping assembly, wherein a closed cavity is formed in the stem cell collecting bag, a through hole is formed in the side surface of the stem cell collecting bag, and the cavity surrounds the through hole; a flow inlet is formed in one side face of the box body, and a flow outlet is formed in the other opposite side face of the box body; the two or more partition plates are sequentially arranged between the flow inlet and the flow outlet in the box body at intervals so as to divide a fluctuating flow channel between the flow inlet and the flow outlet; the clamping assembly is used for clamping the stem cell collecting bag in the flow channel; and the circulating pump is arranged on the outer side of the box body and is arranged between and connectedwith the flow inlet and the flow outlet. The medical stem cell thawing apparatus disclosed by the invention can be used for quickly thawing the stem cell collection bag.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical stem cell thawing device. Background technique [0002] Stem cells are usually stored at low temperature or cryopreservation. Before use, the stem cells must be returned from low temperature to normal temperature to recover the stem cells. At present, frozen stem cells are usually placed in warm water at 40 degrees for rapid rewarming. A medical stem cell thawer is required when rewarming frozen stem cells. [0003] Such as figure 1 As shown, the patent No. CN102161010B discloses a medical stem cell thawing device, which includes a box body 1, a circulating water pump 10, a heating device 8 and a shelf 7; the circulating water pump 10 and the shelf 7 are all arranged in the box body 1 Inside; the heating device 8 is fixed in the box body 1, and the heating device 8 is used to heat the water in the box body 1; the partition frame 7 includes a bottom plate 71 a...

Problems solved by technology

[0004] However, since the circulating water pump 10 is arranged inside the box body 1, and each side plate 72 is provided with multiple rows of through holes, a stable flow channel cannot be formed inside the box body 1, so that when the circulating water pump 10 starts, only the circulating water pump The water near 10 participates in the circulation, and the water far away from the circulating water pump 10 in the cabinet 1 does not participate in the circulation, or the speed of participating in the circulation is relatively slow, which will affect the heat exchange efficiency between the stem cell collection bag and the water in the cabinet 1, so There is an urgent need to address this situation
