Description

Technical Field

[0001] This utility model relates to a desktop storage box for biological sample testing in a laboratory, and more particularly to a placement box for temporary low-temperature preservation of frozen samples on a desktop. Background Technology

[0002] In the daily work of medical laboratories, accurate testing and analysis of biological samples such as blood, urine, and tissues are crucial. These samples usually need to be stored under specific temperature conditions to maintain their activity and prevent degradation. Although traditional large laboratory refrigerators can provide the required low-temperature environment, they are bulky, inconvenient to move, and have high energy consumption. In addition, large refrigerators are not suitable for some small medical institutions or rapid on-site testing.

[0003] With the development of medical technology and the increasing demand for point-of-care testing, a variety of portable refrigeration solutions have emerged on the market; however, these solutions often have some problems, such as the fact that most existing refrigeration boxes are prone to shaking when test tubes are transported or carried by external factors. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a placement box for temporary low-temperature preservation of frozen samples on a desktop.

[0005] The purpose of this utility model can be achieved through the following technical solution: A placement box for temporary low-temperature preservation of frozen samples on a desktop, characterized in that it includes an insulated box body and an insulated box cover. The insulated box body has a receiving cavity, and an insulated base is provided in the receiving cavity. The insulated base has several storage slots for receiving sample tubes from the top. Each storage slot is provided with a limiting clip for holding the sample tube body. A heat-conducting plate connected to the insulated base is provided at the bottom of the insulated box body. The heat-conducting plate is detachably provided with a closed bottom cover.

[0006] The working principle of this invention is as follows: When the sample is briefly removed from the large refrigerator, the sealed bottom cover is fixed to the heat-conducting plate, which seals the heat-conducting plate and isolates it from external heat. At the same time, due to the heat preservation effect of the insulated box, the lid, and the insulated base, the low temperature can be maintained for a certain period of time. If the operation time is long and the low temperature cannot be maintained by heat preservation alone, the sealed bottom cover is removed, and the cryopreservation box is picked up and placed on the cooling plate of a small refrigerator such as a semiconductor refrigerator, so that the heat-conducting plate and the cooling plate come into contact to cool, thereby maintaining the low temperature of the sample tube.

[0007] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, the rear side of the insulated box lid is connected to the insulated box body by a torsion spring, and the front side of the insulated box lid is connected to the front side of the insulated box body by magnetic attraction.

[0008] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, magnetic protrusions are provided on both the front side of the insulated box lid and the front side of the insulated box body, and a handle groove is provided on the magnetic protrusion on the front side of the insulated box lid.

[0009] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, a sealing groove is provided on the top of the insulated box along the circumference direction, and a flexible sealing strip is provided on the bottom of the insulated box lid along the circumference direction.

[0010] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, a temperature sensor is provided at the bottom of the insulated box lid, and a temperature display screen for displaying the temperature inside the containment cavity is provided at the top of the insulated box lid. The temperature sensor and the temperature display screen are electrically connected.

[0011] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, the limiting clip is rotatably connected to one side of the storage slot. The limiting clip includes a main board and elastic clamping legs symmetrically arranged on both sides of the main board. The elastic clamping legs are divided into connecting legs, arc-shaped clamping legs, and upturned outward-curving legs in sequence along the direction away from the main board.

[0012] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, a flexible pad is provided on the inner side of the clamping leg.

[0013] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, the heat-conducting plate is fixedly connected to the heat-insulating base. Multiple locking blocks are provided on the side wall of the heat-conducting plate, and the closed bottom cover has a closed groove for accommodating the heat-conducting plate. Multiple right-angle locking slots for the locking blocks to be inserted are provided on the side wall of the closed groove.

[0014] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, multiple grooves are provided on the outer wall of the closed bottom cover, and a slot is provided at the bottom of the closed bottom cover.

[0015] In the aforementioned placement box for temporary low-temperature preservation of frozen samples on a desktop, the insulation base is made of a phase change material.

[0016] Compared with existing technologies, it has the following advantages:

[0017] 1. The design of the insulated box ensures that after the box is removed from the refrigerator, it maintains a low temperature for a period of time through its own insulation effect, keeping the temperature of the entire cryopreservation box at around -10℃.

[0018] 2. By designing a limiting clip, the sample tube can be clamped during carrying and transportation, keeping the sample tube in place and preventing it from shaking.

[0019] 3. The torsion spring connecting the insulated box lid and the insulated box body allows for automatic reset after opening, preventing staff from forgetting to close the lid after removing the sample tubes and causing insulation failure. The magnetic protrusion design ensures that the lid and body are tightly fastened after being fastened, thus guaranteeing a sealed and insulated environment. The flexible sealing strip not only provides a seal but also acts as a buffer, preventing vibration caused by excessive force when the lid is fastened.

[0020] 4. If there are many samples to be processed and the samples have been removed for a long time, the heat-conducting plate at the bottom of the heat-insulating base can be connected to the cooler to cool the heat-insulating base and maintain the low temperature of the sample tubes for a long time.

[0021] 5. The top of the insulated box is designed with a temperature display, which can monitor the temperature inside the storage chamber in real time, allowing operators to confirm whether to connect to the cooler for cooling. Attached Figure Description

Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1-5As shown, the placement box for temporary low-temperature preservation of frozen samples on the desktop includes an insulated box body 1 and an insulated box cover 2. The insulated box body 1 has a receiving cavity 3, and an insulated base 4 is provided in the receiving cavity 3.

The bottom of the insulated box body 1 is provided with a heat-conducting plate 7 connected to the insulated base 4. The heat-conducting plate 7 is detachably provided with a closed bottom cover 8.

[0030] To elaborate further, the rear side of the insulated box lid 2 is connected to the insulated box body 1 by a torsion spring, and the front side of the insulated box lid 2 is connected to the front side of the insulated box body 1 by a magnetic attraction; the magnetic design ensures that the insulated box lid 2 and the insulated box body 1 are tightly attracted after being fastened, thereby ensuring a sealed and heat-preserving environment.

[0031] To elaborate further, both the front side of the insulated box lid 2 and the front side of the insulated box body 1 are provided with magnetic protrusions 9, and the magnetic protrusions 9 on the front side of the insulated box lid 2 are provided with handle grooves 10; the handle grooves 10 are designed for users to hold and make it easy to open the insulated box lid 2.

[0032] To elaborate further, the top of the insulated box 1 has a sealing groove 11 along the circumference, and the bottom of the insulated box lid 2 has a flexible sealing strip 12 along the circumference. The flexible sealing strip 12 not only seals the box but also cushions it, preventing excessive force when the lid is closed from causing vibration and affecting the sample tube.

[0033] To elaborate further, a temperature sensor 13 is installed at the bottom of the insulated box lid 2, and a temperature display screen 14 is installed at the top of the insulated box lid 2 to display the temperature inside the containment cavity 3. The temperature sensor 13 and the temperature display screen 14 are electrically connected. After taking out the required sample tube, the insulated box lid 2 is closed, and the temperature inside the containment cavity 3 can be observed in real time. Based on the temperature, it can be selected whether to connect to the cooler for cooling.

[0034] To elaborate further, the limiting clip 6 is rotatably connected to one side of the storage slot 5. The limiting clip 6 includes a main board 15 and elastic clamping legs 16 symmetrically arranged on both sides of the main board 15. The elastic clamping legs 16 are divided into connecting legs 17, arc-shaped clamping legs 18, and upward-curved legs 19 in the direction away from the main board 15. When placing the sample tube, first hold your hand under the upward-curved legs 19, then apply force to lift the limiting clip 6 upward until space is made for the sample tube, and then place the sample tube into the storage slot 5. Then, press down the limiting clip 6 to reset it. During the reset process of the limiting clip 6, the sample tube gradually enters between the two elastic clamping legs 16 and is pushed apart by the guide action of the outward curved leg body 19. Finally, the sample tube will be inserted into the arc-shaped clamping leg body 18 to complete the clamping operation. Similarly, when it is necessary to remove the sample tube, simply put your hand under the outward curved leg body 19 and pry it upward. In fact, the limiting clip 6 can also be connected to one side of the storage slot 5 by a torsion spring, which will have an automatic reset function.

[0035] To elaborate further, a flexible pad 20 is provided on the inner side of the clamping leg; the flexible pad 20 serves to increase friction and ensure the sample tube is securely clamped.

The closed bottom cover 8 has a closed groove 22 for accommodating the heat-conducting plate 7. Multiple right-angle slots 23 for the locking blocks 21 to be inserted are provided on the side wall of the closed groove 22. When installing the closed bottom cover 8, the locking block 21 is aligned with the vertical slot of the right-angle slot 23 and inserted. Then, it is rotated to make the locking block 21 be inserted into the horizontal slot of the right-angle slot 23. Disassembly is the same. The top of the conventional closed bottom cover 8 is also provided with a sealing ring to ensure a seal.

[0037] To elaborate further, multiple grooves 24 are provided on the outer wall of the closed bottom cover 8, and a slot 25 is provided on the bottom of the closed bottom cover 8.
