Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a simple device for batch resuscitation of cells. Background Art
[0002] Cell recovery is the process of thawing cells frozen in liquid nitrogen or -80℃ refrigerators and then re-culturing them to restore cell growth. The traditional method of transferring and recovering individual cryopreserved tubes one by one is feasible, but it takes a lot of time and reduces the survival rate of cells. Therefore, cell recovery requires the use of a recovery device to recover cells in batches. However, the existing cell recovery racks often have the following problems when in use. First, when some existing cell recovery racks are in use, the holes for placing cryopreserved tubes in the cell recovery racks slow down the temperature exchange between the water temperature and the cryopreserved tubes due to the thickness of the material, which is not conducive to the rapid melting of cells. Secondly, when some existing cell recovery racks are in use, due to the simultaneous resuscitation of multiple tubes with both hands or uneven force holding with one hand, the humanized operability is low, which reduces the recovery efficiency. Finally, some existing cell recovery racks take up a certain amount of laboratory space after use.
[0003] Therefore, the existing cell recovery rack cannot meet the needs in actual use, so there is an urgent need for improved technology in the market to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a simple device for batch recovery of cells to solve the above-mentioned problems.
[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:
[0006] The utility model is a simple device for batch cell recovery, comprising a main structure, wherein the upper part of the main structure is connected with a knob, a handle is fixed on the knob, a hand grip is fixed on the top of the handle, and a tube hole is opened on the main structure.
[0007] Furthermore, the tube holes are distributed in a circular array with the knob as the center, the hand grip is an inverted triangle structure, and a hook is hung on the hand grip.
[0008] Furthermore, a screw is fixed to the bottom surface of the main structure, the screw passes through the main structure and is connected to the knob, and the screw and the knob are both distributed in the middle of the main structure.
[0009] Furthermore, the handle rod is bendable and the main body structure is elastic.
[0010] The utility model has the following beneficial effects:
[0011] 1. When the cell recovery rack is actually used, the main structure is made of rubber material, which has a certain degree of shrinkage and can effectively protect the cryopreservation tubes and cells. The main structure is provided with multiple tube holes evenly distributed. The upper diameter of these tube holes is larger than the diameter of the cryopreservation tube, but smaller than the diameter of the cryopreservation tube cap. The bottom diameter of the tube hole is smaller than the diameter of the cryopreservation tube, which can ensure that the cryopreservation tube can be stably inserted into the tube hole without falling off or moving, so as to recover and grow the cells.
[0012] 2. When the cell recovery rack is actually used, the hand grip is designed to be an inverted triangle structure, which is convenient for one-hand grip and has uniform force, can reduce the user's hand fatigue and improve the stability and accuracy of operation. A knob is fixed at the bottom of the handle. When the cell recovery rack is used, the device can be folded and hung on the wall, which can save the space occupied by the cell recovery rack. The foldable hand grip is connected to the main structure by screws, which can facilitate the user to disassemble the handle and replace the handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figure 1-4As shown, the utility model is a simple device for batch cell recovery, comprising a main structure 3, a knob 4 is connected to the upper part of the main structure 3, a handle 2 is fixed to the knob 4, a hand grip 1 is fixed to the top of the handle 2, and a tube hole 7 is opened on the main structure 3;
[0022] When the cell recovery rack is actually used, the main structure 3 is made of rubber material, which has a certain degree of shrinkage and can effectively protect the cryopreservation tubes and cells. The main structure 3 is provided with a plurality of evenly distributed tube holes 7. The upper diameter of these tube holes 7 is larger than the diameter of the cryopreservation tube, but smaller than the diameter of the cryopreservation tube cap. The bottom diameter of the tube hole 7 is smaller than the diameter of the cryopreservation tube, which can ensure that the cryopreservation tube can be stably inserted into the tube hole 7 without falling off or moving, so as to recover and grow cells. The cryopreservation tube is the cryopreservation tube currently used for cell recovery on the market.
