[0033] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0034] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0035] In one embodiment, an ultra-low temperature biological storage device is provided. The ultra-low temperature biological storage device can realize remote alarm and timely remind the staff located in the remote place, so that the staff can adjust the temperature value in the ultra-low temperature biological storage device in time to ensure that the biological samples in the ultra-low temperature biological storage device are not damaged by temperature deviation.

[0036] Please refer to Figures 1 to 4 The ultra-low temperature biological storage device of this embodiment mainly includes an ultra-low temperature storage 1, a controller 2 and an alarm 3. The ultra-low temperature storage 1 is used to store biological samples, the controller 2 is used to control the storage temperature in the ultra-low temperature storage 1, and the alarm 3 is used to issue an alarm prompt.

[0037] The ultra-low temperature storage device 1 comprises an outer shell 11, an inner shell 12, a refrigerator 13 and a temperature sensor 14. The outer shell 11 has an outer door 111. The outer shell 11 is a square box, and one side of the square box is the outer door 111. The outer door 111 may also be a partial area of ​​one side of the square box. The outer door 111 is rotatably connected to the outer shell 11 through a rotating connection structure such as a hinge. A handle 1111 may be provided on the outer side of the outer door 111. The handle 1111 facilitates the staff to operate the opening and closing of the outer door 111. The outer door 111 may be connected to the outer shell 11 through a mechanical lock or an electronic lock to form the locking and unlocking of the outer door 111 and the outer shell 11. The edge of the outer door 111 may also be provided with a silicone sealing structure so that when the outer shell 11 is closed with the outer shell 11, a sealed door can be formed to improve the sealing inside the outer shell 11 and achieve a higher thermal insulation effect.

[0038] The volume of the inner shell 12 is smaller than that of the outer shell 11. The inner shell 12 may also be a square box. The inner shell 12 is fixed inside the outer shell 11. The inner shell 12 has a storage chamber 121. The storage chamber 121 is used to place biological samples. The inner shell 12 has an inner door 122. The inner door 122 is a side of the square box inner shell 12. The connection structure between the inner door 122 and the inner shell 12 is the same or similar to the connection structure between the outer door 111 and the outer shell 11. The inner door 122 can be rotated relative to the inner shell 12 to open and close. When the inner door 122 is closed, it forms a sealed connection with the inner shell 12 to form the storage chamber 121 into a closed cavity to ensure the stability of the temperature in the storage chamber 121.

[0039] The inner door 122 and the outer door 111 are located on the same side of the ultra-low temperature storage 1. If the personnel at the workstation need to put in a biological sample, they need to open the outer door 111 and the inner door 122 in sequence. When closing the ultra-low temperature storage 1, they need to close the inner door 122 and the outer door 111 in sequence. The setting of the outer door 111 and the inner door 122 forms two sealing structures, that is, two heat insulation structures, which have a better heat preservation effect on the storage room 121.

[0040] The outer surface of the inner shell 12 and the inner surface of the outer shell 11 also enclose a refrigeration chamber 112 , and the refrigeration chamber 112 and the storage chamber 121 are independently isolated from each other to prevent water vapor or mist in the storage chamber 121 from leaking, and the water vapor or mist leaked from the storage chamber 121 from affecting the components in the refrigeration chamber 112 .

[0041] The refrigerator 13 is installed in the refrigeration chamber 112, and the refrigerator 13 is used to cool the storage chamber 121. The refrigerator 13 has a cooling end, and the cooling end of the refrigerator 13 is attached to the outer surface of the inner shell 12. The portion where the inner shell 12 and the cooling end of the refrigerator 13 are connected is a heat-conducting structure. For example, the inner shell 12 has a copper plate side wall, and the cooling end of the refrigerator 13 is attached to the copper plate side wall of the inner shell 12. Of course, the cooling end of the refrigerator 13 can also extend through the inner shell 12 to the storage chamber 121 to directly cool the storage chamber 121.

[0042] The refrigerator 13 includes two fully enclosed compressors as high and low temperature compressors, that is, the refrigerator 13 includes a low temperature evaporator and a condensing evaporator. The low temperature evaporator has a copper tube, which is the refrigeration end of the refrigerator 13. The copper tube of the low temperature evaporator can be a coil structure, and the copper tube of the coil structure is directly coiled on the outer surface of the inner shell 12. The copper tube of the low temperature evaporator is used for heat exchange with the inner shell 12 to cool the storage chamber 121 in the inner shell 12.

[0043] The gap between the copper tube of the low temperature evaporator and the outer surface of the inner shell 12 is filled with thermal conductive paste, which can increase the contact area between the copper tube of the low temperature evaporator and the outer surface of the inner shell 12 to improve the heat exchange efficiency, that is, improve the refrigeration efficiency.

[0044] The condenser evaporator of the refrigerator 13 is a shell and tube structure, with four threaded copper tubes inside, and adopts a countercurrent heat exchange method.

[0045] The low-temperature evaporator is also equipped with an air heat exchanger, which can allow the low-pressure gas coming out of the low-temperature evaporator to exchange heat with the high-pressure gas before entering the condensing evaporator. This not only reduces the heat load of the condensing evaporator, but also makes full use of the heat.

[0046] The refrigerator 13 may also include a filter, which is usually a wax removal filter, the purpose of which is to effectively remove the paraffin in the refrigeration oil to reduce the possibility of "oil blockage" in the refrigeration system.

[0047] In this embodiment, the temperature sensor 14 is installed in the storage chamber 121 of the inner shell 12, and the temperature sensor 14 is used to monitor the temperature in the storage chamber 121 in real time. The temperature sensor 14 is used to generate a temperature signal representing the real-time temperature value of the storage chamber 121.

[0048] The controller 2 can be installed outside the ultra-low temperature storage 1 as an independent host; or the controller 2 can be installed inside the ultra-low temperature storage as an embedded host. The controller 2 is electrically connected to the refrigerator 13 and the temperature sensor 14. The controller 2 is used to control the refrigeration work of the refrigerator 13. The controller 2 can control the start and stop of the refrigerator 13, and control the refrigeration temperature of the refrigerator 13. The controller 2 is also used to obtain the temperature signal generated by the temperature sensor 14, that is, to obtain the real-time temperature value in the storage room 121.

[0049] A low temperature interval value may be preset in the controller 2, which is the ambient temperature for low temperature storage or low temperature incubation of biological samples and belongs to the target temperature interval value. If the real-time temperature value obtained by the controller 2 is within the low temperature interval value, it is determined that the temperature in the storage chamber 121 is normal; if the real-time temperature value obtained by the controller 2 is not within the low temperature interval value, and the real-time temperature value is greater than or less than the low temperature interval value, it is determined that the temperature in the storage chamber 121 is abnormal, and an alarm signal is generated.

[0050] In other embodiments, in order to improve the accuracy of temperature detection in the storage room 121, the controller 2 can also set the time when the temperature in the storage room 121 is abnormal, for example 1 minute. That is, if the real-time temperature value of the storage room 121 obtained by the controller 2 is greater than or less than the low temperature interval value for more than 1 minute, it is determined that the temperature in the storage room 121 is abnormal, and an alarm signal is generated.

[0051] In this embodiment, the alarm 3 may be an audible and visual alarm, and the alarm 3 may be installed in a room or area relatively far from the ultra-low temperature storage 1. For example, the alarm 3 may be installed in a duty room, while the ultra-low temperature storage 1 is located in a laboratory. The alarm 3 may be connected to the controller 2 by wired or wireless means. When the real-time temperature value acquired by the controller 2 is not within the low temperature interval value, and the real-time temperature value is greater than or less than the low temperature interval value, it is determined that the temperature in the storage room 121 is abnormal, and an alarm signal is generated. The alarm signal is transmitted to the alarm 3 to control the alarm 3 to give an alarm prompt.

[0052] In this embodiment, the ultra-low temperature biological storage device includes an alarm 3 that can be set far away from the ultra-low temperature storage 1. The alarm 3 can be installed in the room or area where the staff is located, so that when the ultra-low temperature storage 1 has a temperature deviation, an alarm prompt can be given through the remote alarm 3. The staff can promptly discover the temperature deviation in the ultra-low temperature storage 1 and promptly adjust and correct the temperature value in the ultra-low temperature storage 1 to ensure that the biological samples in the ultra-low temperature storage 1 will not be destroyed by the temperature deviation.

[0053] Please refer to Figure 5 In one embodiment, a control room 113 independent of the storage room 121 and the refrigeration room 112 may be provided in the housing 11 of the ultra-low temperature storage device 1, and the controller 2 may be installed in the control room 113. The controller 2 is separated from the refrigerator 13 to prevent the heat exchange of the refrigerator from affecting the controller 2.

[0054] The inner and outer surfaces of the control chamber 113 may be provided with a heat insulating layer to achieve heat insulation of the control chamber 113. Of course, the inner or outer surface of the control chamber 113 may be provided with a heat insulating layer, or the control chamber 113 may be provided with a side wall formed of a heat insulating material, which may also play a heat insulating role.

[0055] In one embodiment, the controller 2 may further include a wireless communication module, and the alarm 3 is arranged in the corresponding wireless communication module. The controller 2 may be wirelessly connected to the alarm 3 via the wireless communication module, and the controller 2 may transmit the generated alarm information to the alarm 3 via the wireless communication module to control the alarm 3 to sound an alarm.

[0056] In one embodiment, the wireless communication module of the controller 2 can also be wirelessly connected to the host computer and / or the mobile terminal, and the controller 2 can transmit the generated alarm information to the host computer and / or the mobile terminal through the wireless communication module. The controller 2 can be connected to one or more terminals at the same time. When the controller 2 is connected to multiple terminals at the same time, the alarm information can be sent to multiple terminals at the same time to remind multiple staff members. Among them, the mobile terminal can include mobile phones, laptops and other devices, so that the staff can also obtain the alarm information in other places, and the staff can promptly notify the on-site personnel to maintain the ultra-low temperature storage 1.

[0057] Please refer to Figure 6 In one embodiment, the outer surface of the housing 11 of the ultra-low temperature storage device 1 may be provided with a display screen 15, which is connected to the controller 2 by signal, and is used to display alarm information. The display screen 15 may also display the real-time temperature value in the storage room 121, and the display screen 15 may also display other parameter information.

[0058] The display screen 15 may be a touch screen, and the display screen 15 may be used as an input device to adjust the target temperature value in the storage chamber 121 .

[0059] Please refer to Figure 6 In one embodiment, a printer 16 is provided on the outer surface of the shell 11 of the ultra-low temperature storage device 1. The printer 16 is embedded in the shell 11 as a module. The printer 16 is connected to the controller 2 by signal. The printer 16 is used to print alarm information. The staff can use the alarm information printed by the printer 16 to count the working status of the ultra-low temperature storage device 1 to assist the staff in adjusting the set target temperature value.

[0060] Please refer to Figure 6 In one embodiment, a temperature regulating switch 17 is provided on the outer surface of the shell 11 of the ultra-low temperature storage 1. The temperature regulating switch 17 can be a knob switch or a button switch. The temperature regulating switch 17 is connected to the controller 2 by signal.
