Abstract
Description
An auxiliary device for convenient opening and closing of cryopreservation tubes Technical Field
[0001] This utility model belongs to the field of cryopreservation tube technology, specifically referring to an auxiliary device for conveniently opening and closing cryopreservation tubes. Background Technology
[0002] Cell cryopreservation is a technique that places cells in a low-temperature environment to reduce cellular metabolism for long-term storage. It is one of the main methods of cell preservation, serving as a means of preserving cell lines. By placing cells in liquid nitrogen at -196°C, cryopreservation temporarily removes cells from their growth state while preserving their cellular characteristics. The cells can then be thawed for experimental use when needed. Furthermore, preserving a certain quantity of cells can prevent cell loss due to contamination or other unforeseen events during culture, thus achieving the goal of cell line preservation. Cryopreservation tubes are commonly used for this purpose.
[0003] In practice, on the one hand, because the caps of cryopreservation tubes are small, opening them by hand inevitably leads to contact and increases the chance of contamination, which does not meet the requirements of aseptic operation. When using tweezers, it is also difficult to open and close the caps due to their small size. On the other hand, because the tubes are preserved at low temperatures using liquid nitrogen, when they need to be removed, their extremely low surface temperature can cause frostbite to the user's hands if handled directly. The conventional method is to use a clamping tool, but the clamping tool is prone to falling off due to the smooth surface of the tube, making it very inconvenient to use. Summary of the Invention
[0004] To address the aforementioned problems, this invention proposes an auxiliary device for conveniently opening and closing cryovials. On the one hand, it greatly facilitates the handling of cryovials, preventing them from easily falling off due to their smooth surfaces. On the other hand, it ensures convenient opening and closing of cryovials under sterile laboratory conditions, while reducing the risk of cryovial caps rolling off.
[0005] The technical solution adopted by this utility model is as follows: This utility model provides an auxiliary device for conveniently opening and closing cryovials, including cryovials, a placement rack, a long-handled hook and directional clamping tweezers. The cryovial includes a tube body and a tube cap, which are detachably connected by threads. The long-handled hook is used to extract the cryovial, the directional clamping tweezers are used to open the cryovial, and the placement rack is used to place the tube cap.
[0006] Furthermore, clamping ears are fixedly provided on the two outer side walls of the tube cap, a connecting ear is fixedly connected to the upper end of the second anti-slip texture, an extraction ring is fixedly connected to the upper end of the connecting ear, and a counterweight ear is fixedly provided on the other outer side wall of the tube cap.
[0007] Furthermore, the placement rack includes a counterweight box, with a vertical column fixedly connected to the upper end of the counterweight box, and a placement plate fixedly connected to the upper end of the vertical column. A perforated hole is formed on the placement plate, and a hanging pin is fixedly connected to the inner wall of the perforated hole.
[0008] Furthermore, the long-handled hook includes a long handle, and the lower end of the long handle is provided with a folded hook.
[0009] Furthermore, the directional clamping tweezers include a clamp, a spring is fixedly installed on the inner wall of the clamp, an anti-slip arm is fixedly connected to the lower end of the clamp, and a clamping arm is fixedly connected to one end of the anti-slip arm.
[0010] Furthermore, the outer side wall of the clamping arm is provided with a first anti-slip texture.
[0011] Furthermore, a second anti-slip texture is provided on the inner wall of the clamping ear.
[0012] The beneficial effects of this utility model by adopting the above structure are as follows:
[0013] The long-handled hook and extraction ring allow for easy and convenient removal of cryovials from the 100-hole box, avoiding the risk of dropping the tubes due to their smooth surface when gripped with tweezers. The friction design of the directional clamping tweezers and the tube cap clamping ears facilitates opening and closing of the cryovials. The placement rack, with its perforated holes and hanging pins, connects with the extraction ring to facilitate inverting the cryovial caps, reducing the risk of caps rolling over and becoming contaminated.
