Abstract
Description
Technical Field
[0001] This utility model relates to the field of plasma cryopreservation, specifically a plasma cryopreservation refrigerator and its associated storage unit. Background Technology
[0002] Plasma has a wide range of applications in medicine. Clinically, it is commonly used to treat coagulation disorders, manage acute blood loss, treat traumatic shock, and ensure the smooth progress of surgeries. Therefore, hospitals need to maintain a certain amount of plasma to ensure clinical blood supply needs.
[0003] Fresh frozen blood plasma generally needs to be stored at temperatures below -18°C. Hospitals are typically equipped with specialized low-temperature freezers to meet this requirement. These freezers have precise temperature control systems that can stably maintain the temperature within a specified range to prevent denaturation of components such as proteins in the plasma.
[0004] Currently, hospitals typically place plasma bags on refrigerator shelves or inside metal frames, which are then placed on refrigerator shelves, when storing them in cold storage. Because the plasma bags are stored at temperatures below -18°C, humid air entering the freezer can cause ice to form on the surface of the bags. This can lead to adjacent bags freezing together, making it difficult to separate the frozen bags and ensuring timely plasma supply. Summary of the Invention
[0005] To address the aforementioned technical problems, this utility model proposes a plasma low-temperature freezer storage unit, comprising a plasma bag storage box and plasma bags.
[0006] The plasma bag storage box is formed by four side plates and a bottom plate. At least one matching T-shaped track groove is provided on the two opposite side plates. The matching T-shaped track grooves on the two opposite side plates form a plasma bag storage unit.
[0007] The T-shaped track groove includes a first vertical shaft and a second vertical shaft, both of which are square and connected. On the same cross-section, the cross-sections of the first and second vertical shafts are perpendicular and T-shaped. The side of the second vertical shaft is connected to the inner cavity of the plasma bag storage box.
[0008] The plasma bag includes a plasma bag body, a connecting part, and a fixing part. The cross-sections of the connecting part and the fixing part are both square. One end of the connecting part is fixedly connected to the side of the plasma bag body, and the other end is fixedly connected to the fixing part. On the same cross-section, the cross-section of the fixing part is perpendicular to the cross-section of the connecting part and forms a T-shape.
[0009] The cross-section of the connecting part matches the cross-section of the second vertical shaft, and the cross-sectional area of the connecting part is less than or equal to the cross-sectional area of the second vertical shaft; the cross-section of the fixing part matches the cross-section of the first vertical shaft, and the cross-sectional area of the fixing part is less than or equal to the cross-sectional area of the first vertical shaft.
[0010] The distance between the matching T-shaped track grooves is equal to the distance between the fixing parts on both sides of the plasma bag, so as to ensure that the plasma bag can be placed in the plasma bag storage unit;
[0011] The distance between adjacent plasma bag storage units is greater than the thickness of the plasma bag to ensure that the surfaces of two adjacent plasma bags do not touch after the plasma bags are placed in the plasma bag storage unit.
[0012] Furthermore, the side plate and / or bottom plate of the plasma bag storage box are provided with holes for air circulation.
[0013] Furthermore, the four corners of the first vertical shaft are smooth and burr-free; the four corners of the second vertical shaft are smooth and burr-free; and the four corners of the fixing part are arc-shaped.
[0014] Furthermore, the plasma bag storage box is made of polyurethane foam or polystyrene foam.
[0015] Furthermore, the number of plasma bag storage units is N, where N≥2.
[0016] Furthermore, a partition is provided between two adjacent plasma bag storage units.
[0017] Furthermore, the spacer is made of polyurethane foam or polystyrene foam.
[0018] Beneficial Effects: This utility model relates to a plasma low-temperature freezer storage unit, comprising a plasma bag storage box and plasma bags. The plasma bag storage box is formed by four side plates and a bottom plate. At least one matching T-shaped track groove is provided on two opposite side plates. The matching T-shaped track grooves on two opposite side plates form a plasma bag storage unit. The plasma bag includes a plasma bag body, a connecting part, and a fixing part. Both the connecting part and the fixing part have square cross-sections. One end of the connecting part is fixedly connected to the side of the plasma bag body, and the other end is fixedly connected to the fixing part. On the same cross-section, the cross-section of the fixing part is perpendicular to the cross-section of the connecting part, forming a T-shape. The connecting part and the fixing part constitute a slide rail. In use, the connecting part and the fixing part are inserted along the second vertical shaft and the first vertical shaft respectively to place the plasma bag in the plasma bag storage box. The distance between adjacent plasma bag storage units is greater than the thickness of the plasma bag to ensure that the surfaces of two adjacent plasma bags do not contact each other after the plasma bags are placed in the plasma bag storage unit. This prevents water vapor on the outer surfaces of adjacent plasma bags from freezing together, thus avoiding difficulties in separating frozen plasma bags and ensuring timely plasma supply.

[0022] Figure 4 This is a schematic diagram of the plasma bag storage box structure in Example 2. Detailed Implementation
[0023] Example 1: As Figure 1 As shown, this embodiment proposes a plasma low-temperature freezer storage unit, including a plasma bag storage box 100 and a plasma bag 200.
[0024] The plasma bag storage box 100 is formed by four side plates and a bottom plate. At least one matching T-shaped track groove is provided on the two opposite side plates. The matching T-shaped track grooves on the two opposite side plates form a plasma bag storage unit.
[0025] The T-shaped track groove includes a first vertical shaft 101 and a second vertical shaft 102. Both the first vertical shaft 101 and the second vertical shaft 102 are square. The first vertical shaft 101 and the second vertical shaft 102 are connected. On the same cross-section, the cross-section of the first vertical shaft 101 and the cross-section of the second vertical shaft 102 are perpendicular to each other and form a T-shape. The side of the second vertical shaft 102 is connected to the inner cavity 103 of the plasma bag storage box.
[0026] like Figure 2 , 3 As shown, the plasma bag 200 includes a plasma bag body 201, a connecting part 202, and a fixing part 203. The cross-sections of the connecting part 202 and the fixing part 203 are both square. One end of the connecting part 202 is fixedly connected to the side of the plasma bag body 201, and the other end is fixedly connected to the fixing part 203. On the same cross-section, the cross-section of the fixing part 203 is perpendicular to the cross-section of the connecting part 202 and forms a T-shape.
[0027] The cross-section of the connecting part 202 matches the cross-section of the second vertical shaft 102, and the cross-sectional area of the connecting part 202 is less than or equal to the cross-sectional area of the second vertical shaft 102; the cross-section of the fixing part 203 matches the cross-section of the first vertical shaft 101, and the cross-sectional area of the fixing part 203 is less than or equal to the cross-sectional area of the first vertical shaft 101.
[0028] The distance between the matching T-shaped track grooves is equal to the distance between the fixing parts on both sides of the plasma bag, so as to ensure that the plasma bag can be placed in the plasma bag storage unit;
[0029] The distance between adjacent plasma bag storage units is greater than the thickness of the plasma bag to ensure that the surfaces of two adjacent plasma bags do not touch after the plasma bags are placed in the plasma bag storage unit.
[0030] Furthermore, the side plate and / or bottom plate of the plasma bag storage box 100 are provided with holes 104 for air circulation. The holes 104 on the side plate and / or bottom plate of the plasma bag storage box 100 facilitate the rapid flow of cold air from the low-temperature freezer into the plasma bag storage box, ensuring a uniform air temperature around the plasma bag and thus enabling faster refrigeration of the plasma.
[0031] Furthermore, the four corners of the first vertical shaft 101 are smooth and burr-free; the four corners of the second vertical shaft 102 are smooth and burr-free; and the four corners of the fixing part 203 are arc-shaped. The smooth and burr-free corners of the first vertical shaft 101 and the second vertical shaft 102, along with the arc-shaped corners of the fixing part 203, allow the fixing parts 203 and connecting parts 202 on both sides of the plasma bag to be quickly inserted into the T-shaped track groove and easily removed from it.
[0032] Furthermore, the plasma bag storage box 100 is made of polyurethane foam or polystyrene foam. Making the plasma bag storage box 100 of polyurethane foam or polystyrene foam prevents the plasma bag fixing part 203 and connecting part 202 from freezing together with the first vertical well 101 and the second vertical well 102 of the plasma bag storage box due to surface icing, thus preventing removal.
[0033] Furthermore, the number of plasma bag storage units is N, where N≥2.
[0034] When plasma needs to be stored in a low-temperature freezer, firstly, the connecting parts 202 and fixing parts 203 on both sides of the plasma bag 200 are inserted into the plasma bag storage box along the second vertical shaft 102 and the first vertical shaft 101, respectively, so that the plasma bag is stored upright in the plasma bag storage box. Then, the plasma bag storage box is placed on the shelf of the low-temperature freezer. Because the distance between adjacent plasma bag storage units is greater than the thickness of the plasma bag, the surfaces of two adjacent plasma bags do not touch after the plasma bags are placed in the plasma bag storage unit. This prevents moisture on the outer surfaces of adjacent plasma bags from freezing together, thus avoiding difficulties in separating frozen plasma bags and ensuring timely plasma supply.
[0035] Example 2: As Figure 4 As shown, this embodiment differs from Embodiment 1 in that a spacer 300 is provided between two adjacent plasma bag storage units. Furthermore, the spacer 300 is made of polyurethane foam or polystyrene foam.
