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

Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly. In addition, if there are descriptions involving "first", "second" and so on in the embodiments of the present invention, the descriptions of "first", "second" and so on are only for descriptive purposes, and should not be interpreted as indicating or implying Its relative importance or implicitly indicates the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly o...

Abstract

The invention relates to the technical field of medical instruments, and in particular relates to a stem cell thawing structure. The main technical problem to be solved is how to improve the heat exchange efficiency between a stem cell collection bag in a box body and water. The stem cell thawing structure in the invention comprises a stem cell collection bag, a box body, partition plates, a circulating pump, a heating device and a clamping assembly; a closed cavity is formed in the stem cell collection bag; furthermore, a through hole is formed in the side surface; the cavity surrounds the through hole; a flow inlet is formed in one side surface of the box body; a flow outlet is formed in the other opposite side surface of the box body; more than two 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 collection bag in the flow channel; and the circulating pump is arranged outside the box body, and is connected between the flow inlet and the flow outlet. The stem cell thawing structure disclosed by the invention can realize rapid thawing of the stem cell collection bag.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stem cell thawing structure. 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. Stem cell thaw constructs are required when rewarming cryopreserved stem cells. [0003] like figure 1 As shown, the patent No. CN102161010B discloses a stem cell thawing structure, 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 inside the box body 1 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 and a plura...
