Description

Technical Field

[0001] The utility model relates to laboratory equipment, in particular to a cell cryopreservation tube resuscitation protection clamp. Background Art

[0002] With the rapid development of regenerative medicine and immune cell therapy, it is urgent to establish a standard product process for cell thawing and recovery. At present, the thawing and recovery of cells stored and transported in a frozen state still uses the traditional water bath thawing method, which cannot avoid the risks of contamination and thawing errors. The standard thawing and recovery procedure automatically calculates the end point of the thawing and recovery time through infrared temperature control technology, eliminating the risk of erroneous operation and contamination caused by the operator's subjective speculation. The thawing and recovery of cells is completed by a cell recovery instrument.

[0003] During the cell recovery process, the cell cryopreservation tubes need to be taken out of the extremely low temperature liquid nitrogen and transferred to a water bath for operation. However, due to the poor quality of the cryopreservation tubes or the entry of liquid nitrogen into the cryopreservation tubes during the freezing period, the cryopreservation tubes may explode after the operator takes out the cryopreservation tubes (during the transfer process and in the water bath), thereby causing injuries to the operator. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a cell cryopreservation tube revival protection clamp, which can prevent the cryopreservation tube from exploding and injuring the operator.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a cell cryopreservation tube resuscitation protection clamp, including a transparent protective cover and a clamp; the lower end of the transparent protective cover is open, the side of the transparent protective cover is provided with a through hole connecting the inside and outside of the transparent protective cover, and the inner wall of the transparent protective cover is provided with a mounting seat corresponding to the through hole; the clamp includes a chuck and a handle for driving the chuck to open and close, the chuck extends into the transparent protective cover through the through hole, the handle is arranged outside the transparent protective cover, and the clamp is installed on the mounting seat. Principle of the utility model: the transparent protective cover and the clamp are combined together, so that the protection clamp has the function of clamping the cryopreservation tube and the function of preventing the cryopreservation tube from exploding and injuring the operator; during operation, the handle of the clamp is held, and the upper end of the cryopreservation tube is clamped by the chuck. Since the chuck is arranged in the transparent protective cover, the position between the chuck and the cryopreservation tube can be observed through the transparent protective cover during operation, so as to achieve quick operation.

[0006] As an improvement, the transparent protective cover includes a cylinder and an arc-shaped cover arranged on the upper end of the cylinder.

[0007] As an improvement, the mounting seat is arranged at a middle position of the transparent protective cover, the mounting seat comprises an upper seat and a lower seat, and the through hole passes through the upper seat and the lower seat.

[0008] As an improvement, the chuck includes a first clamp arm and a second clamp arm, the handle includes a first handle rod and a second handle rod, the first clamp arm is connected to the second handle rod to form a first clamp body, the second clamp arm is connected to the first handle rod to form a second clamp body, the first clamp body and the second clamp body are rotatably connected by a pin shaft, and the pin shaft passes through the mounting seat.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The transparent protective cover is combined with the clip, so that the protective clip has the function of clamping the cryopreservation tube and preventing the cryopreservation tube from exploding and injuring the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] like Figures 1 to 3 As shown, a cell cryopreservation tube revival protection clamp comprises a transparent protective cover 1 and a clamp 2. The lower end of the transparent protective cover 1 is open, and the transparent protective cover 1 comprises a cylinder 11 and an arc-shaped cover 12 arranged at the upper end of the cylinder 11. The interior of the transparent protective cover 1 can be observed through the arc-shaped cover 12 of the transparent protective cover 1, and the cryopreservation tube 3 can enter the interior of the transparent protective cover 1 from the lower end opening; the side of the transparent protective cover 1 is provided with a through hole 14 connecting the inside and outside of the transparent protective cover 1, and the inner wall of the transparent protective cover 1 is provided with a mounting seat 13 corresponding to the through hole 14, and the mounting seat 13 is arranged in the middle position of the transparent protective cover 1, and the mounting seat 13 comprises an upper seat and a lower seat, and the through hole 14 passes between the upper seat and the lower seat. The clip 2 includes a clip and a handle for driving the clip to open and close, the clip extends into the transparent protective cover 1 through the through hole 14, the handle is arranged outside the transparent protective cover 1, and the clip 2 is installed on the mounting seat 13; the clip includes a first clip arm 21 and a second clip arm 22, the handle includes a first handle rod 23 and a second handle rod 24, the first clip arm 21 is connected to the second handle rod 24 to form a first clip body, the second clip arm 22 is connected to the first handle rod 23 to form a second clip body, the first clip body and the second clip body are rotatably connected by a pin shaft, and the pin shaft passes through the mounting seat 13. After the clip 2 is combined with the transparent protective cover 1, it does not affect the normal operation of the clip 2.

[0016] The principle of the utility model is as follows: a transparent protective cover 1 and a clamp 2 are combined together so that the protective clamp has the function of clamping the cryogenic tube 3 and the function of preventing the cryogenic tube 3 from exploding and injuring the operator; during operation, the handle of the clamp 2 is held and the upper end of the cryogenic tube 3 is clamped by the clamp. Since the clamp is arranged in the transparent protective cover 1, the position between the clamp and the cryogenic tube 3 can be observed through the transparent protective cover 1 during operation, thereby realizing quick operation.
