Description

Technical Field

[0001] This application relates to the field of biological sample storage technology, and in particular to a biological sample storage device. Background Technology

[0002] With the rapid development of the biopharmaceutical industry, large-scale biobanks have emerged, and the storage capacity of biological samples is increasing. Generally, biological samples such as tissues and cells from clinical or laboratory settings are stored in biobank storage devices.

[0003] In related technologies, the door of a biological sample storage device has a guide portion set in a slide rail, so that the door can be opened and closed by the translation of the guide portion in the slide rail. However, this guide portion protrudes from the door body (for example, when the door body is opened and closed by moving up and down, the guide portion protrudes from the upper end of the door body, making the slide rail longer), resulting in a long slide rail and low space utilization. Summary of the Invention

[0004] In view of the above problems, this application is made in order to provide a biological sample storage device that overcomes or at least partially solves the above problems.

[0005] This application provides a biological sample storage device, comprising: a cavity defining a receiving cavity for storing biological samples, the receiving cavity having an inlet and outlet for the biological samples to enter and exit the receiving cavity; a door disposed at the inlet and outlet for opening and closing the inlet and outlet; at least one guide rail plate, each guide rail plate being fixed to a position in the cavity corresponding to the inlet and outlet, each guide rail plate having a guide rail, the guide rail including a first section extending from an end near the inlet and outlet to an end away from the inlet and outlet, and a second section extending from the end of the first section away from the inlet and outlet to an angle between 80 degrees and 100 degrees with the first section; and a first guide portion disposed on the side of the door corresponding to each guide rail plate, the movement of the first guide portion in the first section being used to shorten or increase the distance between the door and the cavity, the movement of the first guide portion in the second section being used to open and close the inlet and outlet, and the orthographic projection of the first guide portion on the corresponding side being at least partially located on the corresponding side.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one embodiment of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the described embodiments of this application without creative effort are within the scope of protection of this application.

[0024] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this application pertains.

[0025] This embodiment provides a biological sample storage device. Figure 1 This is a schematic diagram of the structure of a biological sample storage device according to some embodiments of this application, with part of the cavity 100 hidden; Figure 2 yes Figure 1 Another perspective view of the structure shown; Figure 3 This is a schematic diagram of the structure of the guide rail plate 300 of a biological sample storage device according to some embodiments of this application; Figure 4 This is a schematic diagram of the structure of the door 200, the first guide portion 210, and the second guide portion of a biological sample storage device according to some embodiments of this application; Figure 5 yes Figure 4Another perspective view of the structure shown.

[0026] The biological sample storage device includes a cavity 100, a door 200, and at least one guide rail 300. The cavity 100 defines a receiving cavity for storing biological samples, and the receiving cavity has an inlet and outlet 111 for the biological samples to enter and exit the receiving cavity. The cavity 100 can be a box, a storage unit, a cabinet, etc., and the biological sample storage device can include refrigerators, cold storage, freezers, liquid nitrogen storage devices including liquid nitrogen tanks (the liquid nitrogen tank may have a box outside), etc. Biological samples can include, but are not limited to, cells, blood, tissues, sperm, and eggs, etc., wherein biological samples can be placed in cryovials, cryopreservation bags, etc., and cryovials and cryopreservation bags can be placed in cryopreservation boxes, and biological samples are stored into the receiving cavity by means of cryopreservation boxes (e.g., cryopreservation racks stored in the receiving cavity).

[0027] A door 200 is positioned at the entrance / exit 111 for opening and closing the entrance / exit 111. Each guide rail 300 is fixed to the cavity 100 at a position corresponding to the entrance / exit 111. Each guide rail 300 has a guide rail 310, which includes a first section 311 extending from one end near the entrance / exit 111 to the end away from the entrance / exit 111, and a second section 312 extending from the end of the first section 311 away from the entrance / exit 111 at an angle between 80 and 100 degrees to the first section 311. A first guide portion 210 is provided on the side of the door 200 corresponding to each guide rail 300. The movement of the first guide portion 210 in the first section 311 shortens or increases the distance between the door 200 and the cavity 100. The movement of the first guide portion 210 in the second section 312 opens and closes the entrance / exit 111. The orthographic projection of the first guide portion 210 on the corresponding side is at least partially located on the corresponding side (preferably, it can be entirely located on the corresponding side).

[0028] Increasing the distance between the door 200 and the cavity 100 facilitates the movement of the door 200 and avoids friction between the door 200 and the cavity 100. Decreasing the distance between the door 200 and the cavity 100 allows the door 200 to close the inlet and outlet 111 more tightly, preventing cold air leakage.

[0029] In this embodiment of the biological sample storage device, the orthographic projection of the first guide portion 210 on the corresponding side is located on the corresponding side, rather than protruding from the door body 200. Compared with biological sample storage devices where the guide portion protrudes from the door body 200, the guide rail 310 is shorter and the space utilization rate is higher.

[0030] In some embodiments, the guide rail 310 further includes a third section 313 extending from one end near the inlet / outlet 111 to the end away from the inlet / outlet 111. The end of the third section 313 away from the inlet / outlet 111 is connected to the middle of the second section 312 (i.e., the entire guide rail 310 is approximately "F" shaped). A second guide portion 220 is provided on the side of the door body 200 corresponding to each guide rail plate 300. The movement of the second guide portion 220 in the third section 313 is used to shorten or increase the distance between the door body 200 and the cavity 100. The movement of the second guide portion 220 in the second section 312 is used to open and close the inlet / outlet 111. The provision of the second guide portion 220 makes the movement of the door body 200 more stable and improves the closing effect when closing the inlet / outlet 111.

[0031] The second guide portion 220 has its orthographic projection on the corresponding side located at least partially on the corresponding side (preferably, entirely on the corresponding side). This further improves space utilization.

[0032] A stop component can be provided at the connection between the second section 312 and the third section 313. The stop component is located on the corresponding guide rail plate 300 and is configured to guide the second guide part 220 into the third guide rail 310 and prevent the first guide part 210 from entering the third guide rail 310. This prevents the first guide part 210 from getting stuck in the third guide rail 310, thus ensuring a smooth opening and closing process for the entire section.

[0033] In some embodiments, the first guide portion 210 includes a first guide member 211 fixedly connected to the door body 200 and a second guide member 212 rotatably connected to the first guide member 211. The first guide member 211 and the second guide member 212 are connected by a first connecting plate 213.

[0034] The stop assembly may include a first stop 410 and a second stop 420. The first stop 410 is disposed on the side of the third section 313 close to the first section 311, and the second stop 420 is disposed on the side of the third section 313 away from the first section 311. The surface of the first connecting plate 213 corresponding to the stop assembly is a plane.

[0035] The second guide section 220 may include a third guide member 221 fixedly connected to the door body 200 and a fourth guide member 222 rotatably connected to the third guide member 221. The third guide member 221 and the fourth guide member 222 are connected by a second connecting plate 223. The surface of the second connecting plate 223 corresponding to the stop assembly is a curved surface that is recessed to the side away from the third section 313.

[0036] This stop assembly has a simple structure, is easy to install, and is structurally stable. In other embodiments, the same function can also be achieved by using an electric stop lever. For example, when the first guide part 210 passes through the third guide rail 310, the electric stop lever blocks the entrance of the third guide rail 310, and when the second guide part passes through the third guide rail 310, the electric stop lever releases the entrance of the third guide rail 310.

[0037] The inlet / outlet 111 can be located on the front end face of the cavity 100. The first section 311 is located above the third section 313. The door 200 opens the inlet / outlet 111 by moving downwards. Specifically, a first guide portion 210 is provided on the upper left side of the door 200, a second guide portion is provided on the lower left side of the door 200, a first guide portion 210 is provided on the upper right side of the door 200, and a second guide portion is provided on the lower right side of the door 200. A guide rail plate 300 is provided on the left and right sides of the inlet / outlet 111. The inlet / outlet 111 being located on the front end face of the cavity 100 facilitates user sampling. The first section 311 being located above the third section 313 and the door 200 opening the inlet / outlet 111 by moving downwards facilitates maintenance, replacement, and other operations on the door 200 and other structures.

[0038] In some embodiments, the at least one guide rail plate 300 includes a first guide rail plate 300 and a second guide rail plate 300 disposed opposite to each other. This allows for smoother movement of the door body 200. For example, guide rail plates 300 may be provided on the left and right sides in the above embodiment, while in other embodiments, guide rail plates 300 may be provided on the top and bottom sides, etc.

[0039] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0040] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
