Technical Field

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

[0002] Biological sample storage devices are specialized equipment used to preserve biological samples (such as blood, tissues, cells, DNA, RNA, etc.). Their core function is to ensure the biological activity and chemical stability of samples by precisely controlling parameters such as temperature, humidity, light, and gas environment, providing reliable data support for scientific research, clinical diagnosis, drug development, and other fields.

[0003] Traditional storage boxes have a simple internal structure design with fixed sample racks, which cannot be flexibly adjusted according to sample type, such as test tubes, cryopreservation boxes, blood bags, etc., resulting in wasted space.

[0004] Therefore, this application provides a mobile biological sample storage device to solve the above-mentioned problems. Utility Model Content

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] This embodiment provides a mobile biological sample storage device, such as... Figures 1-3 As shown, the mobile biological sample storage device includes a storage box 1, a box cover 11 screwed to the top of the storage box 1, a base 12 fixedly connected to the bottom of the storage box 1, a caster wheel 13 provided at the bottom of the base 12, a longitudinally movable layered shelf 2 provided inside the storage box 1, a screw 41 rotatably connected to the bottom of the layered shelf 2 inside the storage box 1, and a motor 4 with an output shaft connected to the screw 41 inside the base 12, wherein the layered shelf 2 is slidably connected to the inner wall of the storage box 1.

[0028] The layered rack 2 has at least three layers 21 arranged longitudinally and in a linear array. A honeycomb storage block 3 is inserted between each layer 21. The honeycomb storage block 3 has several honeycomb holes 31 arranged in a ring array on its side for inserting different sample containers. The honeycomb storage block 3 is made of polyurethane foam.

[0029] A refrigeration device 5 is installed inside the base 12. A cold air well 23 is opened at the bottom of the shelf 2 and connected to the cold air outlet 51 of the refrigeration device 5. The interior of the shelf 21 is connected to the cold air well 23.

[0030] In use, the motor 4 inside the base 12 starts according to the size and quantity of biological sample containers to be stored. Its output shaft drives the screw 41 to rotate. Since the layer rack 2 is screwed to the screw 41 and slidably connected to the inner wall of the storage box 1, the layer rack 2 will move longitudinally along the screw 41 when the screw 41 rotates, thereby adjusting the height of the layer rack 2. After the layer rack 2 is moved to the appropriate height, the required layer is exposed to meet the placement requirements of different sample containers. The biological sample container is inserted into the corresponding honeycomb hole 31 on the honeycomb storage block 3. Since the honeycomb storage block 3 is made of polyurethane sponge, it can play a certain role in fixing and cushioning the sample container. The cooling device 5 starts to work. The generated cold air is evenly distributed in the storage box 1 through the cold air outlet 51, the cold air channel 23 and the inside of the shelf 21 to preserve the biological sample at low temperature. The air permeability of the sponge material allows the cold air to directly contact the sample container for cooling. When it is necessary to move the device, the entire storage device can be easily moved to the designated location by the moving wheels 13 set at the bottom of the base 12.

[0031] Specifically, the inner wall of the storage box 1 has a limiting slide rail 16, and the side of the layer rack 2 has a slide groove 22 that slides and connects with the limiting slide rail 16. Through the cooperation of the limiting slide rail 16 and the slide groove 22, the movement trajectory of the layer rack 2 is effectively restricted, making the layer rack 2 more stable during lifting and lowering, avoiding the situation where the sample container falls or is damaged due to the shaking of the layer rack 2, and improving the safety of sample storage.

[0032] Specifically, each shelf 21 has a ventilation slot 24 on the side near the cold air channel 23 to connect the cold air channel 23 and the interior of the shelf 21. Each shelf 21 has a number of equally spaced air holes 211 on its surface. The cold air generated by the refrigeration device 5 enters the cold air channel 23 from the cold air outlet 51, enters the interior of the shelf 21 through the ventilation slot 24, and then is evenly distributed to each shelf 21 area in the storage box 1 from the number of equally spaced air holes 211 on the surface of the shelf 21, so as to achieve uniform cooling of the biological sample.

[0033] It should be noted that the thickness of the honeycomb storage block 3 is equal to the distance between two adjacent layers 21. When installing the honeycomb storage block 3, since its thickness is equal to the distance between two adjacent layers 21, the honeycomb storage block 3 can be inserted tightly between the layers 21 to form a stable storage structure.

[0034] Furthermore, the honeycomb holes 31 on different honeycomb storage blocks 3 are set with different pore sizes; the honeycomb holes 31 with different pore sizes can meet the storage needs of various sample containers of different specifications, greatly improving the versatility and adaptability of the device, and can be widely used in biological sample storage in various scientific research, clinical and drug development fields.

[0035] Furthermore, a telescopic handle 15 is fixedly connected to the side of the storage box 1. Two wheels 13 are symmetrically arranged on the bottom of the base 12 near the telescopic handle 15. Feet 14 are symmetrically fixed on the bottom of the base 12 away from the wheels 13. When the device needs to be moved, the telescopic handle 15 is pulled out to the appropriate length. Then, by pulling the handle, the two wheels 13 on the bottom of the base 12 near the handle roll, driving the entire device to move. When the device moves to the designated position, the feet 14 are lowered to contact the ground, supporting the device and keeping it stable and stationary.

[0036] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
