In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0027] Reference will now be made to Figures 1-3 The anaerobic medical refrigeration preservation box 100 according to the embodiment of the utility model is described below.

[0028] As Figure 1 shown, the anaerobic medical refrigeration preservation box 100 according to the embodiment of the utility model comprises a refrigerator 10, an anaerobic box 20 and a gas path control device 40. The refrigerator 10 has a refrigeration chamber 101. The anaerobic box 20 is installed in the refrigeration chamber 101. The gas path control device 40 is arranged outside the refrigerator 10. The gas path control device 40 is connected to the anaerobic box 20 through a gas pipe 30 to extract air in the anaerobic box 20 and supply the required gas for the anaerobic box 20. The side wall of the refrigerator 10 has a detection hole 13. The gas pipe 30 extends to the refrigeration chamber 101 through the detection hole 13.

[0029] In the above technical solution, the refrigeration chamber 101 in the refrigerator 10 serves as the main part of the preservation box, which is used to provide a low-temperature environment to slow down the metabolic rate of the sample and prolong the preservation time.

[0030] Optionally, the temperature of the refrigeration chamber 101 can be set in a range suitable for the survival of anaerobic microorganisms but not frozen, such as between 2℃ and 8℃. Alternatively, the temperature of the refrigeration chamber 101 is adjusted according to user requirements, which is not limited here.

[0031] It is worth mentioning that the experimental refrigerator itself is equipped with a standard detection hole 13, so it does not need to be additionally drilled. This technical solution ingeniously uses the existing detection hole 13, so that the gas pipe 30 can smoothly penetrate from the outside of the refrigerator 10 into the inside of the refrigeration chamber 101.

[0032] The anaerobic box 20 is directly installed in the refrigeration chamber 101, so that it can directly use the low-temperature environment of the refrigeration chamber 101, and at the same time, the gas composition in the inside of the anaerobic box 20 can be adjusted by the gas path control device 40 to meet the anaerobic environment.

[0033] In some optional embodiments, a sealing member is arranged on the inner wall of the detection hole 13 to wrap the outer wall of the gas pipe 30. The sealing member can be a soft and durable material such as rubber, silicone or specially designed elastic plastic, etc. These materials have good elasticity and wear resistance, and can tightly fit the outer wall of the gas pipe 30 to form a sealed barrier. The design shape and size of the sealing member are accurately matched with the outer diameter of the gas pipe 30 to ensure the best sealing effect. Due to the elasticity of the sealing member, it can tightly fit on the gas pipe 30, and even in the case of gas pressure change or vibration of the gas pipe 30, it can maintain a stable sealing state. Alternatively, the sealing member can be a soft rubber plug with a hole, and the gas pipe 30 passes through the hole of the soft rubber plug.

[0034] Of course, the sealing member can not be arranged at the detection hole 13. Experiments have shown that the amount of cold air leakage at this position is small without the sealing member, and it does not affect the refrigeration effect of the refrigeration chamber 101.

[0035] Optionally, the anaerobic box 20 is provided with a suitable culture rack or container for placing the samples to be cultured.

[0036] The gas path control device 40 is arranged outside the refrigerator 10 and connected to the anaerobic box 20 through the gas pipe 30. The gas pipe 30 passes through the detection hole 13 of the refrigerator 10 into the refrigeration chamber 101 and is connected to the gas interface of the anaerobic box 20. Since the experimental refrigerator used in the present application is an existing technology, the structure of the refrigerator 10 is not improved to reduce the cost, so the refrigerator 10 does not have extra space to arrange the gas path control device 40, and therefore the gas path control device 40 is arranged outside the refrigerator 10. In this way, it also avoids the condensed water generated in the low-temperature environment of the refrigerator 10 from flowing into the gas path control device 40, avoiding the water inlet failure of the gas path control device 40.

[0037] The gas path control device 40 is used to extract the air in the anaerobic box 20 and control the gas composition input into the anaerobic box 20. The gas composition can be nitrogen, hydrogen, carbon dioxide, etc. to create an anaerobic or low-oxygen environment, which is conducive to the growth of anaerobic microorganisms.

[0038] As Figures 1-2As shown, the anaerobic medical refrigeration preservation box 100 according to some embodiments of the present application further comprises: a support frame 50, the support frame 50 is installed in the refrigerator 10, and the anaerobic box 20 is installed on the support frame 50.

[0039] The support frame 50 is arranged in the anaerobic medical refrigeration preservation box 100, provides a stable support platform for the anaerobic box 20, enhances the stability and safety of the anaerobic box 20 in the refrigeration chamber 101, ensures the firmness under various operating conditions, and can also avoid the space interference problem that may occur between the trachea 30 and the anaerobic box 20. The presence of the support frame 50 enables the anaerobic box 20 to be stably placed, while ensuring the smoothness of the trachea 30 path, optimizing the space layout inside the anaerobic medical refrigeration preservation box 100, and improving the reliability of the anaerobic medical refrigeration preservation box 100.

[0040] Optionally, the support frame 50 defines a support cavity 501 for installing the anaerobic box 20, and the support frame 50 is further provided with an adjusting device to adjust the height of the support cavity 501. The adjusting device can be a bolt, a slide rail, etc.

[0041] In this way, the user can adjust the height and position of the anaerobic box 20 according to actual needs, thereby optimizing space utilization and meeting the preservation and culture needs of different samples, while helping the user to fine-tune according to the size and weight of the anaerobic box 20, thereby achieving a better support effect.

[0042] As shown in the drawings, Figure 2 As shown, the anaerobic medical refrigeration preservation box 100 according to some embodiments of the present application, the opposite two side walls of the refrigerator 10 are respectively provided with mounting strips 15, and the mounting strips 15 are provided with a plurality of mounting holes 151 distributed vertically. The two ends of the support frame 50 are connected to the mounting holes 151 of the two mounting strips 15, and the support frame 50 can be installed on mounting holes 151 of different heights to realize height adjustment.

[0043] These mounting strips 15 not only provide a stable mounting basis for the support frame 50, but also enable the height of the support frame 50 to be adjusted.

[0044] The mounting strips 15 are provided with a plurality of mounting holes 151 distributed vertically, and the number and spacing of the mounting holes 151 can be set according to actual needs to meet the support strength requirements of anaerobic boxes 20 of different sizes and weights. By flexibly selecting the position of the mounting hole 151, the user can adjust the height of the support frame 50 according to the actual situation to adapt to different preservation and culture needs, while ensuring the stability and safety of the overall structure.

[0045] The number of the mounting strips 15 on each side is not limited. One mounting strip 15 can be arranged on one side, and two mounting strips 15 can be arranged on the other side. Alternatively, two mounting strips 15 are arranged on each of the opposite side walls of the refrigerator 10. Alternatively, mounting strips 15 are arranged on the side walls of the refrigerator 10 opposite to the refrigerator doors, in addition to the mounting strips 15 arranged on the opposite side walls of the refrigerator 10. In this way, mounting strips 15 are arranged on three side walls, and the number of the mounting strips 15 on each side wall is at least one.

[0046] In some optional embodiments, as shown in Figure 2 The support frame 50 forms at least two vertically arranged support cavities 501, and each support cavity 501 is arranged with an anaerobic box 20. The anaerobic box 20 is detachably mounted on the support frame 50.

[0047] Specifically, the support frame 50 is configured to have a plurality of independent support cavities 501 arranged in the vertical direction. Each support cavity 501 has sufficient space and structural strength to mount an anaerobic box 20. By vertically placing the anaerobic box 20, the space utilization is improved, so that more anaerobic boxes 20 can be accommodated in a limited laboratory space, and each anaerobic box 20 can obtain independent support and protection, avoiding interference and influence between each other.

[0048] The anaerobic box 20 and the support frame 50 are in a detachable mounting mode. This means that users can easily remove or mount the anaerobic box 20 from the support frame 50 according to actual needs, thereby improving the flexibility and ease of use of the anaerobic medical refrigerated storage box 100. At the same time, it is also convenient for users to clean, maintain and replace the anaerobic box 20.

[0049] In actual application, users can flexibly select anaerobic boxes 20 of different sizes and types according to the types and quantities of samples and the requirements of storage conditions, and install them in the corresponding support cavities 501 of the support frame 50. Since the anaerobic box 20 is detachable, users can conveniently adjust the layout and number of the anaerobic boxes 20 to adapt to different research and clinical needs.

[0050] In some optional embodiments, as shown in Figure 1 and Figure 2 The support frame 50 includes a vertical beam 52, a connecting beam 53, and a mounting beam 54. Through the cooperation of the vertical beam 52, the connecting beam 53, and the mounting beam 54, a stable and flexible support system is formed.

[0051] The four vertical beams 52 are vertically arranged at the four corners of the refrigeration chamber 101. The connecting beams 53 are arranged in at least two layers with different heights. On the same height layer, there are two connecting beams 53 distributed along the left-right direction, and each connecting beam 53 extends along the front-back direction and is connected between two vertical beams 52. The mounting beams 54 are arranged in at least two layers with different heights. The layers where the mounting beams 54 are arranged correspond to the layers where the connecting beams 53 are arranged. On the same height layer, the front ends of the two connecting beams 53 are connected to one mounting beam 54, and the rear ends of the two connecting beams 53 are connected to another mounting beam 54. On the same height layer, the two connecting beams 53 and the two mounting beams 54 form a support cavity 501 above them.

[0052] In the above technical solution, the four vertical beams 52 serve as the basic structure of the support frame 50 and are vertically arranged at the four corners of the refrigeration chamber 101. These vertical beams 52 provide the necessary vertical support for the entire support frame 50 and ensure the stable connection of the support frame 50 with the side walls of the refrigeration chamber 101. Optionally, the vertical beams 52 are made of high-strength materials such as stainless steel or aluminum alloy. The high-strength vertical beams 52 can withstand the weight of the anaerobic tank 20 and the samples inside it.

[0053] Secondly, the connecting beams 53 are located on the left and right sides of the refrigeration chamber 101, and each connecting beam 53 is connected between two vertical beams 52, forming a horizontal support structure of the support frame 50. These connecting beams 53 not only enhance the overall stability of the support frame 50, but also provide reliable connection points for the mounting beams 54. Optionally, the connecting beams 53 are made of high-strength materials such as stainless steel or aluminum alloy. The high-strength connecting beams 53 can ensure that they do not deform or displace when bearing the weight of the anaerobic tank 20.

[0054] The mounting beams 54 are connected between the left and right connecting beams 53, forming a horizontal platform inside the support cavity 501 for mounting the anaerobic tank 20. Specifically, the mounting beams 54 are pre-provided with connecting holes 541, and the bottom of the anaerobic tank 20 is provided with connecting ears 22 that are connected to the connecting holes 541 of the mounting beams 54 through bolts.

[0055] Optionally, the number and spacing of the connecting holes 541 can be adjusted according to the size and weight of the anaerobic tank 20 to meet various preservation needs.

[0056] The bottom of the anaerobic tank 20 is provided with connecting ears 22 that match the connecting holes 541 on the mounting beams 54. Optionally, the connecting ears 22 are made of solid metal material.

[0057] The connecting lug 22 is provided with a bolt hole, so that the bolt passes through the bolt hole and the connecting hole 541 to connect the anaerobic box 20 and the mounting beam 54. Specifically, the user only needs to align the connecting lug 22 of the anaerobic box 20 with the corresponding connecting hole 541 on the mounting beam 54, and then fix it with a bolt, so that the installation of the anaerobic box 20 can be easily completed. This detachable installation method not only facilitates the user to clean, maintain and replace the anaerobic box 20, but also improves the flexibility and expandability of the anaerobic medical refrigerated storage box 100.

[0058] According to some embodiments of the anaerobic medical refrigerated storage box 100, the refrigerator 10 has a refrigerator door, which is a transparent door. The anaerobic box 20 has a switch door 24, which is provided with a viewing window 241, and the switch door 24 is arranged opposite to the refrigerator door.

[0059] In the above technical solution, the refrigerator 10 of the anaerobic medical refrigerated storage box 100 is provided with a transparent door. This transparent door can provide the user with an intuitive and clear observation window. Through this transparent door, the user can clearly see the storage state of the anaerobic box 20 and its internal samples in the refrigeration chamber 101, without the need to frequently open the refrigerator door for inspection, thereby reducing the temperature fluctuation in the refrigeration chamber 101, and being beneficial to maintaining the stability of the samples and prolonging the storage time.

[0060] Meanwhile, each anaerobic box 20 is provided with a switch door 24, and the switch door 24 is provided with a viewing window 241. The viewing window 241 enables the user to directly observe the state of the internal samples of the anaerobic box 20, such as whether there is pollution and how the growth is, without opening the switch door 24 of the anaerobic box 20. This design helps to improve the convenience of user operation, avoids the fluctuation of the culture environment caused by frequent opening of the switch door 24, and is beneficial to the stable growth and storage of the samples.

[0061] It is worth mentioning that the switch door 24 of the anaerobic box 20 is arranged opposite to the refrigerator door. Such a layout design enables the user to intuitively see the state of all anaerobic boxes 20 and their internal samples when opening the refrigerator door, without the need to search for or move the anaerobic boxes 20 in the refrigeration chamber 101. This arrangement can not only improve work efficiency, but also help to avoid sample damage or loss caused by misoperation or negligence.

[0062] In order to ensure transparency and durability, the transparent door and the viewing window 241 can be high-strength and high-transparency glass or plastic pieces. These material pieces not only have good light transmission, but also can withstand a certain pressure and impact, ensuring the stability and safety of the refrigerated storage box during long-term use.

[0063] Referring to Figure 1 and Figure 3According to the anaerobic medical refrigeration preservation box 100 of some embodiments of the utility model, further include: sensor 60 that sets on anaerobic tank 20, sensor 60 includes the barometer 61 for detecting the gas pressure of anaerobic tank 20 inside.

[0064] Specifically, by setting the barometer 61 on the anaerobic tank 20, the user can real-time understand the gas pressure condition in the anaerobic tank 20, so as to timely adjust the culture condition and ensure the sample in a better preservation state. In addition, the presence of the barometer 61 also facilitates the user to regularly maintain and calibrate the anaerobic tank 20, further improving the reliability and stability of the anaerobic medical refrigeration preservation box 100.

[0065] In some optional embodiments, the sensor 60 is electrically connected with the gas path control device 40, so that the control host 42 of the gas path control device 40 records the detection result of the sensor 60. In some further optional embodiments, the sensor 60 is electrically connected with the gas path control device 40, the gas path control device 40 can real-time receive the data from the sensor 60 such as the barometer 61, and automatically adjust the gas pressure in the anaerobic tank 20 according to the data, so as to ensure the sample in a better preservation state, to improve the automation degree of the anaerobic medical refrigeration preservation box 100, and to further enhance its control ability to the internal environment.

[0066] In some optional embodiments, the gas path control device 40 automatically adjusts the gas pressure in the anaerobic tank 20. Then the user only needs to set the required anaerobic condition, and the gas path control device 40 will automatically monitor and adjust without frequent manual intervention. This not only saves manpower and time, but also reduces the risk of sample damage caused by human operation errors.

[0067] Of course, in the above scheme, the sensor 60 can also not be electrically connected with the gas path control device 40, and after observing the detection result of the sensor 60, the staff can also manually operate to adjust the gas pressure in the anaerobic tank 20 through the gas path control device 40.

[0068] According to the anaerobic medical refrigeration preservation box 100 of some embodiments of the utility model, the anaerobic tank 20 is at least two, and each anaerobic tank 20 is connected with the gas path control device 40 through an independent gas pipe 30, to realize independent control.

[0069] Here, the design of the independent gas pipe 30 means that each anaerobic box 20 can independently receive gas regulation and distribution from the gas path control device 40. This design allows users to set different gas environments, such as oxygen concentration, nitrogen concentration, or the proportion of other inert gases, for the characteristics of the samples in each anaerobic box 20, thereby creating anaerobic conditions suitable for sample preservation. The ability of independent control helps to improve the flexibility and adaptability of the anaerobic medical refrigeration preservation box 100, and can provide corresponding growth environment according to the different growth cycles of organisms, thereby improving efficiency.

[0070] In addition, the design of the independent gas pipe 30 connection helps to improve the stability and reliability of the anaerobic medical refrigeration preservation box 100 as a whole. Since each anaerobic box 20 is connected to the gas path control device 40 through an independent gas pipe 30, even if one of the anaerobic boxes 20 fails or needs maintenance, it will not affect the normal operation of the other anaerobic boxes 20, thereby reducing the overall downtime caused by problems with a single anaerobic box 20.

[0071] In some alternative embodiments, referring to Figure 3 , the gas path control device 40 includes a gas storage cylinder 41 and a control host 42, and the gas storage cylinder 41 contains the gas required by the anaerobic box 20.

[0072] The control host 42 is provided with a first air valve 421 and a second air valve 422. The first air valve 421 is connected to the gas pipe 30. The second air valve 422 is used to communicate with the gas storage cylinder 41.

[0073] In the above technical solution, the gas storage cylinder 41 serves as a gas supply source and internally pre-stores the gas required by the anaerobic box 20. These gases are usually inert gases used to create an oxygen-free or low-oxygen environment.

[0074] The first air valve 421 and the second air valve 422 of the control host 42 are connected to the control host 42 and are uniformly scheduled by the control host 42.

[0075] Specifically, the first air valve 421 is configured to be directly connected to the gas pipe 30. The gas pipe 30 serves as a channel for gas circulation, one end of which communicates with the inside of the anaerobic box 20, and the other end is connected to the control host 42 through the first air valve 421. When it is necessary to discharge the gas in the anaerobic box 20, the control host 42 will open the first air valve 421 according to the pre-set program or operation instruction, thereby allowing the gas in the anaerobic box 20 to be smoothly discharged to the external environment through the gas pipe 30, achieving effective replacement of the gas.

[0076] The second air valve 422 is configured to fill the anaerobic box 20 with the required inert gas. When the experiment requires the gas environment in the anaerobic box 20 to be supplemented or updated, the control host 42 will receive the corresponding instruction, and then open the second air valve 422. At this time, the inert gas pre-stored in the gas cylinder 41 enters the air pipe 30 through the second air valve 422, and is finally delivered to the inside of the anaerobic box 20.

[0077] By setting the gas path control device 40, the functions of air inlet and air outlet are integrated and shared with the same air pipe 30. Further, the additional opening on the anaerobic box 20 is reduced, the structural complexity of the anaerobic box 20 is reduced, the potential gas leakage risk is reduced, and the layout compactness and reliability of the whole system are further improved.

[0078] It is worth noting that the gas path control device 40 can adopt a known scheme in the prior art, and the gas path control device 40 itself is not the core point of the present application scheme, so it will not be repeated here.

[0079] Optionally, the air pipe 30 is provided with a check valve. The check valve is used to prevent the backflow of gas in the pipeline.

[0080] In some optional embodiments, the control host 42 further comprises a metal shell 425 and a display screen 426. The first air valve 421 and the second air valve 422 are both arranged in the metal shell 425. The display screen 426 is arranged on the metal shell 425.

[0081] This is because the metal shell 425 has certain corrosion resistance and impact resistance, which can reduce or even avoid the erosion and accidental collision of the external environment, thereby protecting the internal gas path control components from damage.

[0082] Among them, the first air valve 421 is arranged in the metal shell 425, so that the overall structure of the system is more compact and consistent.

[0083] Optionally, the gas cylinder 41 can be arranged inside or outside the metal shell 425 according to actual needs. If the gas cylinder 41 is small or the system space allows, it can be directly placed inside the metal shell 425 to further improve the integration and safety of the system.
