[0023] Unless otherwise defined, the technical terms or scientific terms used in the present application shall have the ordinary meanings understood by those of ordinary skill in the art to which the present application belongs.

[0024] The present application provides a biological sample storage device 10, Figure 1 which is a cross-sectional view of the biological sample storage device 10 according to some embodiments of the present application (the plate groove 210 and the rack protrusion 310 are not shown); Figure 2 which is a top view of the mounting plate 200 according to some embodiments of the present application; Figure 3 is Figure 2 a cross-sectional view of the shown section A-A; Figure 4 which is a structural schematic diagram of the first cryopreservation rack 300 according to some embodiments of the present application; Figure 5 It is a bottom view of the first cryopreservation rack 300 according to some embodiments of the present application.

[0025] The biological sample storage device 10 includes a cavity 100 and a first cryopreservation rack 300. The cavity 100 defines a receiving cavity 110, and a mounting plate 200 is disposed in the receiving cavity 110. A plate protrusion or a plate groove 210 is provided at the top of the mounting plate 200. The first cryopreservation rack 300 is used for storing biological samples. A rack groove or a rack protrusion 310 is provided at the bottom of the first cryopreservation rack 300. The first cryopreservation rack 300 is fixed above the mounting plate 200 through the cooperation of the rack groove and the plate protrusion, or the cooperation of the rack protrusion 310 and the plate groove 210.

[0026] Understandably, the cavity 100 can include a box body, a cabinet body, a storage body, a tank body, etc., and the biological sample storage device 10 can include a refrigeration system for providing cooling capacity to the accommodation cavity 110. Correspondingly, the biological sample storage device 10 can include a refrigerator, a freezer, a cold storage, a liquid nitrogen tube, etc.

[0027] The mounting plate 200 can be arranged in the accommodation cavity 110 in various ways such as by an axis, a support rod, insertion, etc. For example, a rotating shaft is arranged in the accommodation cavity 110, and the mounting plate 200 is fixed to the rotating shaft, so that the rotation of the rotating shaft can drive the rotation of the mounting plate 200. The first cryopreservation rack 300 can store biological samples by placing cryopreservation boxes, and the cryopreservation boxes can be used to place cryotubes or cryopreservation bags, and the cryotubes or cryopreservation bags are used to place biological samples. Among them, the rack protrusion 310 or the rack groove can be arranged at the bottom of the first cryopreservation rack 300 or on the side of the first cryopreservation rack 300.

[0028] The biological sample storage device 10 provided in this embodiment realizes the fixation of the cryopreservation rack through the groove and the protrusion, and the fixation method is simple and does not require a complex structure to be set.

[0029] In some embodiments, the mounting plate 200 is provided with a first opening 220, and at least one of the plate grooves 210 is arranged on the circumferential outer side of the first opening 220; the first cryopreservation rack 300 includes a bottom plate 320, and at least one of the rack protrusions 310 is arranged on the circumferential outer side of the bottom plate 320, and the at least one rack protrusion 310 corresponds to and is adapted to the at least one plate groove 210 one by one. The first cryopreservation rack 300 has a first state. When the first cryopreservation rack 300 is in the first state, the bottom plate 320 closes the first opening 220, and each rack protrusion 310 is located in the corresponding plate groove 210.

[0030] The cooperation of the plate groove 210 and the rack protrusion 310 provides support to support the first cryopreservation rack 300 on the mounting plate 200. The setting of the first opening 220 can reduce the overall weight and cost.

[0031] In some embodiments, when the first cryopreservation rack 300 is in the first state, the upper end surface of the bottom plate 320 is flush with the upper end surface of the mounting plate 200. Thus, the distance between the mounting plate 200 and the top end of the first cryopreservation rack 300 is reduced.

[0032] In some embodiments, the biological sample storage device 10 further includes a lifting device, and the first cryopreservation rack 300 further has a second state in which it is lifted by the lifting device to be separated from the mounting plate 200. Thereby, the automation level of the biological sample storage device 10 can be improved. Specifically, the lifting device can lift the first cryopreservation rack 300 out of the accommodation cavity 110, so that operations such as taking and placing biological samples on the first cryopreservation rack 300 can be performed.

[0033] In some embodiments, the at least one plate groove 210 includes a first plate groove 211, a second plate groove 212, and a third plate groove 213. The first plate groove 211 is disposed on a first side portion of the first opening 220, the second plate groove 212 is disposed on a second side portion of the first opening 220, the third plate groove 213 is disposed on a third side portion of the first opening 220. The first side portion is adjacent to the second side portion, the third side portion is adjacent to the second side portion, and the first side portion is opposite to the third side portion. Thereby, the stability of the first cryopreservation rack 300 in multiple directions can be ensured.

[0034] In some embodiments, the distance between at least one of the first plate groove 211 and the third plate groove 213 and the second side portion is greater than the distance from the fourth side portion of the first opening 220. Thereby, the first cryopreservation rack 300 has more uniform stability.

[0035] In some embodiments, the mounting plate 200 is fixed with a plurality of the first cryopreservation racks 300, the accommodation cavity 110 has a top opening 111, and the mounting plate 200 is rotatably disposed in the accommodation cavity 110. The setting of the plurality of first cryopreservation racks 300 can increase the storage capacity, and the rotation of the mounting plate 200 can adjust the positional relationship between the first cryopreservation rack 300 and the top opening 111, so that different cryopreservation racks can be located below the top opening 111.

[0036] In some embodiments, the biological sample storage device 10 further includes at least one second cryopreservation rack 400, and the at least one second cryopreservation rack 400 is disposed in the accommodation cavity 110 and below the mounting plate 200. The setting of the second cryopreservation rack 400 can increase the storage capacity, and the setting of stacking the cryopreservation racks up and down reduces the space required to be reserved above the cavity 100 for lifting the rack, improving the space utilization rate.

[0037] In some embodiments, the biological sample storage device 10 further includes a first driving device for driving the plurality of first cryopreservation racks 300 to rotate, and a second driving device for driving the at least one second cryopreservation rack 400 to rotate. Thereby, the convenience of extracting each cryopreservation rack is improved.

[0038] In some embodiments, the mounting plate 200 is provided with a second opening 230, and the second cryopreservation rack 400 enters and exits the accommodation cavity 110 through the second opening 230 and the top opening 111. In other embodiments, the second cryopreservation rack 400 can be extracted through the first opening 220 (i.e., first lift and remove the first cryopreservation rack 300).

[0039] Regarding the embodiments of the present application, it should also be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0040] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be subject to the protection scope of the claims.
