Description

Technical Field

[0001] This invention relates to refrigerator technology, specifically to a refrigerator for medical blood storage tanks. Background Technology

[0002] The storage quality of blood and blood products is directly related to clinical transfusion safety and is a crucial link in ensuring patient blood safety for medical institutions. To ensure that blood products maintain their biological activity and efficacy during storage, the storage process must strictly adhere to requirements regarding temperature stability, environmental cleanliness, and full traceability. According to the specific provisions of WS 399—2023 "Blood Storage Standard," whole blood and red blood cell components must be stored in a constant temperature environment of 2℃~6℃, while plasma components must be stored under deep cryogenic freezing conditions of ≤-18℃ to prevent cell denaturation or component deactivation. Therefore, the storage environment control of medical blood tanks is particularly important, as any temperature fluctuations or contamination risks can have irreversible effects on blood quality.

[0003] Currently, most refrigerated cabinets used for storing medical blood containers employ a single-door or double-door design, typically equipped with multiple adjustable shelves inside for categorizing and storing blood storage containers of different sizes. In practice, retrieving a blood container requires opening the sealed door. However, when large quantities of blood containers need to be retrieved frequently, or when the door is opened multiple times in a short period, a significant amount of cold air leaks out of the refrigerated cabinet, causing a substantial rise in internal temperature. This not only affects the stability of the storage temperature but also accelerates frost formation on the evaporator surface, reducing the efficiency of the refrigeration system and increasing energy consumption. More seriously, temperature fluctuations directly impact the quality of blood and blood products, potentially leading to problems such as hemolysis of red blood cells and denaturation of plasma proteins, thereby threatening the safety and effectiveness of clinical blood transfusions. Summary of the Invention

[0004] The purpose of this invention is to provide a refrigerator for medical blood storage tanks to overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a refrigerator for medical blood storage tank, comprising a cabinet body, wherein a refrigerator cavity is provided inside the cabinet body, and a sealed door corresponding to the refrigerator cavity is provided on the cabinet body. Several guide frames are installed in an array at equal intervals inside the refrigerator cavity, and a right-angle groove is provided at one end of each of the four adjacent guide frames facing each other, and a guide passage is formed between the four adjacent right-angle grooves.

[0006] The inner side of the guide walkway is slidably connected to a rear connecting seat. The end of the rear connecting seat is provided with a placement box. Several blood storage tanks are placed sequentially inside the placement box. The end of the placement box is installed with a front connecting seat located outside the refrigeration chamber. The inside of the cabinet is equipped with an insulation partition to seal the opening of the refrigeration chamber. The insulation partition has a sealing groove corresponding to the front connecting seat.

[0007] Furthermore, sealing blocks are installed on the opposing surfaces of the rear connecting seat and the front connecting seat, and sealing rings are provided on the sides of the sealing blocks. A sealing retaining ring located inside the refrigeration cavity is installed on the surface of the sealing groove, and the shape and size of the sealing retaining ring are adapted to the sealing blocks and sealing rings.

[0008] Furthermore, the shape and size of the rear connector are the same as those of the front connector, while the size of the sealing block is smaller than that of the rear connector.

[0009] Furthermore, the thermal insulation partition, rear connecting seat, front connecting seat, sealing block, and sealing retaining ring are all made of thermal insulation materials.

[0010] Furthermore, when the rear connecting seat moves into the refrigeration cavity and contacts the inner wall of the refrigeration cavity, the outer surface of the front connecting seat is flush with the outer surface of the insulation partition.

[0011] Furthermore, when the sealed door is closed, the inner surface of the sealed door is in contact with the surface of the thermal insulation partition.

[0012] Furthermore, guide strips are symmetrically arranged on both sides of the bottom of the inner wall of the placement box, and the distance between the guide strips on both sides corresponds to the specifications of the blood storage tank.

[0013] Furthermore, the surface of the front connector is provided with a groove.

[0014] Compared with the prior art, the refrigerated cabinet for medical blood storage tanks provided by the present invention has the following beneficial effects:

[0015] 1. This medical blood storage tank refrigerator features a modular design that integrates the internal components of the refrigerator chamber through the cooperation of guide frames, rear connecting seats, front connecting seats, placement boxes, and insulation partitions. This design effectively reduces the heat exchange area between the refrigerator chamber and the external environment when placing or removing blood storage tanks, thereby minimizing the leakage of cold air from the refrigerator and ensuring that the internal temperature remains relatively stable.

[0016] 2. This dedicated refrigerated cabinet for medical blood storage tanks achieves efficient isolation between the refrigeration chamber and the external environment through the tight fit of the sealing block, sealing ring, and sealing retaining ring. During refrigeration operations, the sealing block and matching sealing ring on the front connecting seat accurately embed into the sealing retaining ring, forming a reliable sealing barrier that effectively prevents the intrusion of outside air. When it is necessary to pull out the storage box to retrieve the blood storage tank, the sealing block and its corresponding sealing ring on the rear connecting seat also embed into the sealing retaining ring, maintaining the airtight state of the refrigeration chamber and significantly reducing the leakage of internal cold air. This design not only effectively prevents the leakage of cold air but also ensures the continuous stability of the temperature inside the refrigeration chamber, providing strong protection for the safe storage of blood and helping to maintain the quality and activity of the blood.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1:

[0029] Please see Figures 1-3 A refrigerator for medical blood storage tanks includes a cabinet body 1, a refrigerator cavity 101 inside the cabinet body 1, a sealing door 102 corresponding to the refrigerator cavity 101 on the cabinet body 1, and several guide frames 2 are installed in an array at equal intervals inside the refrigerator cavity 101. Right angle grooves 21 are provided at the opposite ends of four adjacent guide frames 2, and a guide passage is formed between the four adjacent right angle grooves 21.

[0030] The inner side of the guide aisle is slidably connected to a rear connecting seat 3. The end of the rear connecting seat 3 is provided with a placement box 31. Several blood storage tanks are placed inside the placement box 31 in sequence. The end of the placement box 31 is installed with a front connecting seat 32 located outside the refrigeration chamber 101. The inside of the cabinet 1 is installed with an insulation partition 33 to seal the opening of the refrigeration chamber 101. The insulation partition 33 is provided with a sealing groove 34 corresponding to the front connecting seat 32.

[0031] When needed, the operator opens the sealing door 102 on one side and then pulls the front connecting seat 32 outward to move it outward and move the placement box 31 outward. At this time, the operator can directly take out the blood storage container inside the placement box 31. During this process, the contact channel between the refrigeration chamber 101 and the outside world is only a part of the sealing groove 34, which can effectively reduce the leakage of cold air inside the refrigeration chamber 101.

[0032] Example 2:

[0033] This embodiment provides a technical solution based on the above embodiments: sealing blocks 4 are installed on the opposite side surfaces of the rear connecting seat 3 and the front connecting seat 32, sealing rings 41 are provided on the side of the sealing blocks 4, and sealing retaining rings 42 located inside the refrigeration cavity 101 are installed on the surface of the sealing groove 34. The shape and size of the sealing retaining rings 42 are adapted to the sealing blocks 4 and the sealing rings 41.

[0034] It should be added that the shape and size of the rear connecting seat 3 are the same as those of the front connecting seat 32. The size of the sealing block 4 is smaller than that of the rear connecting seat 3, so that the sealing ring 42 can not only cooperate with the sealing block 4 to seal the refrigeration chamber 101, but also limit the movable distance of the rear connecting seat 3. Thus, when the blood is taken out of the placement box 31, the pull-out distance of the front connecting seat 32 can be quickly determined, and the cooperation state between the sealing block 4 and the sealing ring 42 on the rear connecting seat 3 can also be quickly determined.

[0035] Furthermore, the insulation partition 33, rear connecting seat 3, front connecting seat 32, sealing block 4, and sealing retaining ring 42 are all made of thermal insulation materials, so that the sealing and thermal insulation effect at the junction of the refrigeration chamber 101 and the external environment can be maintained in a good state.

[0036] It should be further explained that when the rear connecting seat 3 moves into the refrigeration cavity 101 and contacts the inner wall of the refrigeration cavity 101, the outer surface of the front connecting seat 32 is flush with the outer surface of the insulation partition 33. Furthermore, when the sealing door 102 is closed, the inner surface of the sealing door 102 is in contact with the surface of the insulation partition 33. This ensures that when one side of the sealing door 102 is opened to collect blood, the other side of the sealing door 102 remains in contact with the remaining surfaces of the front connecting seats 32 and the corresponding surfaces of the insulation partition 33. This provides secondary protection for the sealing and insulation of the refrigeration cavity 101, greatly reducing the probability of cold air leakage from the refrigeration cavity 101.

[0037] When the placement box 31 is pulled outward for blood collection, the sealing block 4 and sealing ring 41 on the rear connecting seat 3 are embedded inside the sealing retaining ring 42, thereby effectively sealing and insulating the refrigeration chamber 101, making it difficult for the cold air inside the refrigeration chamber 101 to leak out.

[0038] Example 3:

[0039] This embodiment provides a technical solution based on the above embodiment: guide bars 5 are symmetrically arranged on both sides of the bottom of the inner wall of the placement box 31, and the distance between the two guide bars 5 corresponds to the specifications of the blood storage tank, so that the blood storage tank is placed neatly and orderly in the placement box 31, which facilitates retrieval and placement.

[0040] Example 4:

[0041] This embodiment provides a technical solution based on the above embodiments: the surface of the front connecting seat 32 is provided with a pull groove 6, which makes it convenient for the operator to pull the front connecting seat 32 outward.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
