Description

Technical Field

[0001] This utility model relates to medical refrigeration equipment, and more particularly to a multi-compartment cryopreservation box. Background Technology

[0002] In existing technology, cryopreservation bags for umbilical cord blood are placed in aluminum cryopreservation boxes. Multi-compartment cryopreservation bags are multi-unit structures composed of multiple cryopreservation chambers. These bags are used in stages, with one or more chambers cut off each time, and the remaining chambers returned to the cryopreservation box for further freezing. After being partially cut, the multi-compartment cryopreservation bag becomes smaller. When placed in the cryopreservation box, this creates empty space, allowing the smaller bag to slide freely. This sliding can cause it to collide with the box walls, which is detrimental to its preservation. Furthermore, each chamber of the multi-compartment cryopreservation bag has an information label. When the bag slides, these labels move out of the viewing window of the cryopreservation box, making it impossible to observe the umbilical cord blood sample information from the outside. Opening the cryopreservation box for inspection would affect work efficiency and is also detrimental to the preservation of the umbilical cord blood sample. Utility Model Content

[0003] The purpose of this invention is to provide a multi-compartment cryopreservation box that enables safe freezing, convenient access, and management of multi-compartment freezer bags.

[0004] A multi-compartment cryopreservation box includes a box body 20 and a box lid 10 for cryopreserving multi-compartment cryopreservation bags 30. The bottom surface 21 of the box body is provided with a plurality of partition strips 22 protruding into the inside of the box body. The partition strips 22 divide the box body 20 into a plurality of cryopreservation compartments 23 on the bottom surface 21 of the box body. The box lid is provided with a viewing window 11.

[0005] Furthermore, in order to observe the information label of the blood sample, the window 11 is rectangular in shape, and the window 11 corresponds to one of the cryopreservation cells 23.

[0006] Furthermore, in order to accommodate the structure of the multi-compartment freezer bag, the dividing strip 22 separates a pipeline rotation area 26 on one side of the bottom surface of the box body. The pipeline rotation area is adjacent to the first cryopreservation cell 23a, and the position of the viewing window 11 corresponds to the first cryopreservation cell 23a.

[0007] Furthermore, in order to determine the state inside the cryopreservation box, the bottom surface 21 of the box body is provided with an observation port 24, and the box lid is provided with a light-transmitting hole 12.

[0008] Furthermore, in order to effectively identify the state within each cryopreservation cell, each observation port 24 corresponds to one cryopreservation cell 23, and each light-transmitting hole 12 corresponds to one observation port 24.

[0009] Furthermore, in order to obtain better observation results, the observation port 24 is an elongated hole, and the light-transmitting hole 12 is a round hole.

[0010] Furthermore, a preferred separator structure is that the separator 22 is a separator formed by stamping, and the interval L1 of the separator 22 corresponds to the interval L2 of the freezer compartment 31 of the multi-compartment freezer bag 30.

[0011] The beneficial effects of this utility model are as follows: A dividing strip is set at the bottom of the cryopreservation box to divide the cryopreservation box into multiple cryopreservation compartments. Each freezing compartment of the multi-compartment cryopreservation bag can be stably maintained in one cryopreservation compartment, which avoids the multi-compartment cryopreservation bag from sliding in the cryopreservation box and can effectively ensure the safety of cryopreservation protection of umbilical cord blood samples. An observation port is set for each cryopreservation compartment, and a light-transmitting hole is set on the opposite side of the observation port, so that it is easy to see whether there is a freezing compartment in the cryopreservation compartment, which facilitates the cryopreservation management of umbilical cord blood samples.

[0012] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] Example 1:

[0022] like Figures 1 to 4 A multi-compartment cryopreservation box includes a box body 20 and a box lid 10, for cryopreserving multi-compartment cryopreservation bags 30.

[0023] The multi-compartment cryopreservation bag 30 has multiple cryopreservation compartments 31, each containing a blood sample of umbilical cord blood. The bag also includes a blood collection tube 33. In this embodiment, the multi-compartment cryopreservation bag 30 has five cryopreservation compartments 31, forming a multi-compartment structure. The compartments 31 have identical dimensions and the same spacing L2 between them. Each compartment has an information label 32. Typically, a multi-compartment cryopreservation bag stores the same type of umbilical cord blood sample, and the information labels on the compartments are also identical. Each compartment 31 can be cut off individually for use, allowing the multi-compartment cryopreservation bag to be used multiple times.

[0024] The box body 20 and the lid 10 can be made of aluminum alloy sheet or stainless steel sheet by stamping. The lid can be flipped open or closed.

[0025] Multiple dividing strips 22 are provided on the bottom surface 21 of the box body. The dividing strips 22 protrude towards the inside of the box body, dividing the bottom surface 21 of the box body into multiple cryopreservation compartments 23 and a pipeline rotation area 26. The pipeline rotation area 26 is located on one side of the bottom surface of the box body. In this embodiment, as shown... Figure 5 As shown, five dividing strips 22 divide the bottom surface of the box into five cryogenic compartments and a tubing revolving area 26 from bottom to top. The cryogenic compartment adjacent to the tubing revolving area is defined as the first cryogenic compartment 23a. The dividing strips 22 are formed by stamping. The interval L1 of the dividing strips 22 corresponds to the interval L2 of the freezer compartments 31 of the multi-compartment freezer bag 30, that is, the interval L1 of the dividing strips 22 and the interval L2 of the freezer compartments 31 are of equal length. Thus, each cryogenic compartment 23 can accommodate one freezer compartment 31. After the box lid 10 is closed, the dividing strips 22 prevent the freezer compartments 31 from sliding arbitrarily within the cryogenic box, ensuring that each freezer compartment 31 remains within one cryogenic compartment 23.

[0026] The lid 10 has a viewing window 11 for viewing the information label 32 in the freezer compartment. The information label 32 in the freezer compartment 31 can be viewed through the viewing window 11 without opening the lid. In this embodiment, the viewing window 11 is a rectangular opening, and its position corresponds to the first cryogenic compartment 23a. After the multi-compartment freezer bag 30 is inserted into the box, the information label 32 in the freezer compartment of the first cryogenic compartment 23a corresponds to the position of the viewing window 11. During normal use, the freezer compartment 31 in the first cryogenic compartment 23a remains until the end.

[0027] To allow observation of whether the freezer compartments 31 are present in each cryogenic cell 23 without opening the lid, an observation port 24 is provided on the bottom surface 21 of the box. Each observation port 24 corresponds to one cryogenic cell 23. In this embodiment, five observation ports 24 are provided, each corresponding to one cryogenic cell 23 (including the first cryogenic cell 23a). To clearly observe whether the freezer compartments 31 are present in the cryogenic cells, the observation port 24 is an elongated hole located in the center of the cryogenic cell. The observation port 24 extends along the arrangement direction of the cryogenic cells 23, that is, the extension direction of the observation port 24 is perpendicular to the separator strip 22.

[0028] To accurately determine whether each cryogenic compartment 23 contains a freezer compartment 31, a light-transmitting hole 12 is provided on the lid. Each light-transmitting hole 12 corresponds to an observation port 24. By viewing the observation port 24 from the bottom surface 21 of the box, if the corresponding cryogenic compartment 23 does not contain a freezer compartment 31, light can be seen passing through the light-transmitting hole, thus reliably determining whether a freezer compartment 31 exists in the cryogenic compartment 23. The observation port 24 corresponding to the viewing window 11 allows light to pass through the viewing window 11. For each of the other observation ports 24, a light-transmitting hole 12 is provided on the lid. In this embodiment, the lid has four light-transmitting holes 12, corresponding to four cryogenic compartments 23, with a viewing window 11 located at the position corresponding to the first cryogenic compartment 23a. To minimize the impact on the structural strength of the lid, the light-transmitting holes 12 are round.

[0029] Because frost will condense on the cryopreservation box under low temperature freezing conditions, in this embodiment, the opening side of the box body is provided with a notch 25, and the corresponding lid is also provided with a notch 13. When the lid is closed, the notch on the box body and the lid form an auxiliary opening, and the cryopreservation box can be opened with the help of an opening tool.

[0030] The multi-compartment cryopreservation bag 30 is in the box body 20, with each cryopreservation compartment 31 placed in a cryopreservation cell 23 (including the first cryopreservation cell 23a), and the blood collection tube 33 is coiled inside the box body 20 through the tubing loop area 26.

[0031] The multi-compartment freezer bag 30 can be used multiple times, with one or more freezer compartments 31 cut off each time.

[0032] like Figure 6 As shown, in this embodiment, two of the five freezer compartments 31 of the multi-compartment freezer bag 30 need to be cut off for use, and the remaining three freezer compartments of the multi-compartment freezer bag 30 are put back into the box body 20. Each of the three freezer compartments 31 is located in a cryogenic storage compartment 23, and one of the freezer compartments is ensured to be in the first cryogenic storage compartment 23a, so that it corresponds to the viewing window 11 for viewing the information label.

[0033] After the partition box lid 10 is closed, due to the limiting effect of the partition strip 22, the remaining three freezer compartments 31 are all confined within their respective cryogenic compartments 23 (regardless of whether the three freezer compartments are in a separated state or in a piped state), so that each freezer compartment cannot move freely and remains stable within the cryogenic box.

[0034] like Figure 7 As shown, when viewed from the lid, information label 32 can be viewed through window 11 to obtain information about the umbilical cord blood sample. The contents of the cryopreservation box can also be observed through the light-transmitting hole 12, but the small size of the hole will affect clarity.

[0035] like Figure 8 As shown, to clearly observe the contents of the cryovial, one can look from the bottom of the box. The observation port 24 on the bottom of the box has a large opening, allowing for a clear view of the contents. Combined with the light-transmitting hole 12 on the lid, when a cryovial 23 does not contain a freezing chamber 31, the light-transmitting hole 12 can be clearly seen through the observation port 24, thus confirming that the cryovial 23 does not contain a freezing chamber 31. In the embodiment shown, the two cryovial 23 located on the sides of the cryovial box do not contain freezing chambers 31, while the three middle cryovial 23 contain freezing chambers 31. There is no need to open the lid to check.

[0036] Example 2:

[0037] like Figure 5 A multi-compartment cryopreservation box, this embodiment is a structural simplification of embodiment one.

[0038] Since the presence of a freezer compartment 31 can be clearly determined through the viewing window 11, in this embodiment, an observation port 24 is not provided at the position of the first freezer compartment 23a, simplifying the structure.

[0039] However, it should be noted that the observation port 24 at the location of the first cryopreservation compartment 23a still helps to determine the condition inside the cryopreservation box from the bottom surface 21 of the box.

[0040] This invention allows blood samples to remain stable during random sampling, meeting the needs of multiple uses and providing accurate cryopreservation information without opening the cryopreservation box. It ensures safe and stable low-temperature preservation of blood samples and facilitates cryopreservation management.
