Description

Technical Field

[0001] The utility model belongs to the technical field of stem cell preservation devices, and particularly relates to a convenient adipose mesenchymal stem cell preservation device. Background Art

[0002] Stem cell preservation devices are generally stored in liquid nitrogen tanks and need to be preserved at low temperatures to prevent them from being damaged. The preservation device is generally a low-temperature resistant bracket with multiple sets of protective boxes set up in a pull-out manner inside the bracket. The device needs to be taken out, but a problem with existing preservation devices is that when the bracket is taken out and a certain set of boxes needs to be opened, since the partition is an integrated setting, opening a certain set will still open the entire partition, and other boxes that do not need to be opened may also move, posing a risk of falling. For this reason, we propose a convenient adipose mesenchymal stem cell preservation device to solve the above problem. Utility Model Content

[0003] The utility model provides a convenient adipose mesenchymal stem cell storage device, which solves the problems in the prior art.

[0004] The technical solution of the utility model is achieved in this way:

[0006] A rod is also rotatably arranged inside the bracket body, and the rod is transitionally matched with the bracket body. An active buckle is slidably arranged between the broken ends of the rod, and the active buckle can be rotated independently to fasten the box body.

[0007] Furthermore, a sliding cylinder is integrally provided at the broken end of the rod, and the movable buckle is slidably provided inside the sliding cylinder.

[0008] Furthermore, a roller is movably sleeved on the outer side of the movable buckle, and a groove is correspondingly provided along the side wall of the box body and corresponding to the roller, and the roller can be embedded in the groove so that the box body is clamped and fixed.

[0009] Furthermore, the roller is made of rubber.

[0010] Furthermore, a handle is movably provided on the upper end of the bracket body.

[0011] Furthermore, the support body also includes an inner wall of the support body, and a pop-up member is provided between the box body and the inner wall of the support body, and the pop-up member can push the box body out from the inner side of the support body.

[0012] Furthermore, the ejection member includes a connection seat installed on the inner wall of the frame, and a movable rod is elastically arranged on the inner side of the connection seat, and one end of the movable rod is against the side wall of the box body.

[0013] Furthermore, a torsion spring is provided between the movable rod and the connecting seat.

[0014] Furthermore, the liquid nitrogen tank comprises a tank body, and a tank cover is sealed on the upper end of the tank body.

[0015] Furthermore, the inner wall of the tank is also provided with a heat-insulating layer.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are:

[0017] In the utility model, a rod is provided, and a movable buckle is slidably provided at the fracture of the rod. By sliding the movable buckle, the movable buckle can be removed from the box body, so that a box body can be opened separately to take out the stem cells stored therein. At the same time, all the movable buckles can be removed from the box body by rotating the rod, and selection can be made according to selection needs.

[0018] In the utility model, a pop-up member is provided. Since no handle or the like is installed on the box body, the box body can be squeezed, and the movable rod in the pop-up member can push the box body out of the bracket body through the torque force of the torsion spring, thereby facilitating the removal of the box body.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: Figure 1-6 As shown, a portable adipose-derived mesenchymal stem cell storage device includes a liquid nitrogen tank and a storage rack 40 stored in the tank. The storage rack 40 includes a support body 401. A plurality of boxes 403 are arranged inside the support body 401. The boxes 403 store stem cells. Empty slots for the boxes 403 to slide and store are provided on the inner side of the support body 401 and the boxes 403, respectively. The boxes 403 can slide and store in the empty slots.

[0029] Among them, Figure 3-4 As shown, a rod 404 is also rotatably arranged inside the bracket body 401, and the rod 404 and the bracket body 401 are transitionally matched, so that the rod 404 can be easily rotated in the bracket body 401. The rod 404 is a long rod broken, and a movable buckle 405 is slidably arranged between the broken ends of the rod 404. The movable buckle 405 can be rotated separately to fasten the box body 403. In order to facilitate the sliding of the movable buckle 405, a sliding cylinder 409 is integrally arranged at the broken end of the rod 404, and the movable buckle 405 is slidably arranged inside the sliding cylinder 409.

[0030] When stem cells need to be taken out, the storage rack 40 can be taken out from the tank first. Figure 3As shown, a handle 402 is movably provided at the upper end of the bracket body 401. The storage rack 40 can be taken out as a whole by passing a low-temperature resistant hook or a clamp through the handle 402. If all the box bodies 403 need to be taken out, all the movable buckles 405 can be detached from the box bodies 403 by rotating the rod 404, and all the box bodies 403 can be taken out. If a certain group or several groups of box bodies 403 are to be taken out, the rod 404 can be slightly rotated first, and the movable buckle 405 can be detached from the box body 403 by holding the movable buckle 405, and the box bodies 403 of a certain group or several groups can be taken out.

[0031] In addition, if Figure 4 As shown, in order to ensure the clamping force, a roller 406 is movably sleeved on the outer side of the movable buckle 405, and a groove 410 is correspondingly provided along the side wall of the box body 403 and the roller 406, and the roller 406 can be embedded in the groove 410, so that the box body 403 is clamped and fixed, wherein the roller 406 is made of elastic material, such as rubber material, etc.;

[0032] Since the box body 403 is not provided with a handle, in order to facilitate the removal of the box body 403, Figure 5-6 As shown, the bracket body 401 also includes an inner wall 408 of the bracket, and an ejection member 407 is further provided between the box body 403 and the inner wall 408 of the bracket, and the ejection member 407 can push the box body 403 out from the inner side of the bracket body 401, wherein the ejection member 407 includes a connecting seat 4071 installed on the inner wall 408 of the bracket, and a movable rod 4073 is elastically provided on the inner side of the connecting seat 4071, and one end of the movable rod 4073 is against the side wall of the box body 403, and a torsion spring 4072 is further provided between the movable rod 4073 and the connecting seat 4071 to ensure that the movable rod 4073 is full of elasticity. Considering the low temperature situation, the storage rack 40 as a whole should be made of a low temperature resistant material to ensure that the torsion spring 4072 and other movable parts can move, and the torsion spring 4072 can give a certain elastic force to the movable rod 4073 by pressing the box body 403, so that the box body 403 can slide out of the bracket body 401, so that the box body 403 can be taken out conveniently;

[0033] Among them, Figure 2 As shown, the liquid nitrogen tank includes a tank body 10, and a tank cover 20 is sealed at the upper end of the tank body 10; an insulation layer 30 is also provided on the inner wall of the tank body 10 to ensure a low temperature environment in the tank.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
