Description

Technical Field

[0001] This utility model relates to the field of sample storage technology, and in particular to a straw insulated container. Background Technology

[0002] In the biomedical field, reproductive cells such as sperm, eggs, and embryos need to be cryopreserved. Currently, hospitals and research institutions generally place sample boxes containing test tubes into liquid nitrogen tanks manually. This method is not only inefficient and carries significant storage risks, but also typically requires a large number of liquid nitrogen tanks, occupying considerable space and volume, without achieving a high storage capacity.

[0003] The construction of a sample library requires a high investment, including tens of thousands of cryovials. Traditional cryovials have multiple regularly arranged round or square holes inside, which limits the number of cryovials that can be stored and only serves the purpose of storage, without providing cold preservation. Moreover, they are not easily compatible with external robotic arms, resulting in low storage efficiency and thus high construction costs for sample libraries. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the problems existing in the above or prior art, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a wheat tube cooling container that can keep liquid nitrogen cold by setting multiple sets of microbubble structures inside the sample box body, preventing liquid nitrogen loss and thus keeping the wheat tube warm. The hollow guide rod further reduces the container's weight, making it suitable for gaseous liquid nitrogen storage environments. Furthermore, counterweights can be optionally installed inside the guide rod and on the outer wall of the sample box to ensure stability and prevent floating when used in liquid nitrogen storage environments. Clamping grooves enhance reliability during handling, and grooves on both sides reduce product weight, increasing the device's lifespan and storage capacity. The grooves on both sides also improve efficiency during cooling or heating, facilitate manual handling, and make it easier to fix the clamping position on platforms or drawers. A guide slope facilitates the slow contact between the bottom of the wheat tube and the guide slope until it enters the tube hole. The tube hole has a polygonal structure, ensuring line contact with the tube when it enters, and includes an exhaust channel for easy entry. The tube has a cavity that can hold liquid nitrogen. When the container is used in a liquid nitrogen environment, the exhaust channel can also allow liquid nitrogen to flow, so that the straw inside the container is always protected at a low temperature, effectively reducing the damage to the sample during the movement.

[0078] Preferably, the open area 6 is located at the position of the guide member 3. By setting the open area, the contact area between the liquid nitrogen and the straw can be increased when the straw is fully immersed in liquid nitrogen, thereby achieving rapid cooling of the straw.

[0079] Furthermore, the sample box body 1 is also provided with an RIFD chip slot 7, which can hold an RIFD chip for the device to identify.

[0080] In summary, the sample container body 1 is made of low-temperature resistant PPO special plastic and micro-foamed through injection molding, forming a large number of closed-loop microbubble structures inside, creating a structure similar to a "thermal insulation chamber". The thermal conductivity of gas is much lower than that of solid materials. When heat passes through this microbubble structure, the conduction path is continuously interrupted by the bubbles, resulting in better cold insulation and effectively extending the liquid nitrogen storage time, ensuring the safe and effective protection of biological samples. The micro-foaming injection molding process, with its numerous closed-loop microbubble structures, makes the container lighter, saving materials and reducing costs. The hollow guide rod further reduces the container's weight, making it suitable for gaseous liquid nitrogen storage environments. Furthermore, counterweights can be optionally installed inside the guide rod and on the outer wall of the sample container to further enhance its performance. The container remains stable and does not float when used in a liquid nitrogen storage environment. Clamping grooves enhance reliability during handling, while side slots reduce weight and increase lifespan and storage capacity. Side slots also improve efficiency during cooling or heating, making manual handling easier. It is more convenient for fixing clamps on platforms or drawers. A guide slope facilitates slow contact between the bottom of the straw and the guide slope until it enters the tube hole. The tube hole has a polygonal structure, ensuring line contact with the straw upon entry, and includes an exhaust channel for easy straw entry. The tube hole has a groove to hold liquid nitrogen, and the exhaust channel also allows for liquid nitrogen flow, ensuring the straw inside remains at a low temperature, effectively reducing sample damage during transport. The open area increases the contact area between liquid nitrogen and the straw, enabling rapid cooling. Example 2

[0082] Furthermore, the plastic material is a low-temperature resistant PPO special plastic.

[0083] Furthermore, the micro-foaming injection molding process creates a large number of closed-cell microbubble structures inside.
