Description

Technical Field

[0001] The present application relates to the technical field of biological sample storage, and in particular to a biological sample storage device. Background Art

[0002] With the rapid development of the biopharmaceutical industry, large-scale biobanks have emerged, and the storage volume of biological samples is increasing. Generally, biological samples such as tissues and cells in clinical or laboratory settings are placed in biological sample storage devices for storage. Figure 1 As shown, Figure 1 It is a schematic diagram of a biological sample storage device 10 for taking and placing biological samples in the related art. A freezing rack 110 is arranged in a cavity 100 of the biological sample storage device 10. The biological sample storage device 10 is also provided with a lifting device 200. The lifting device 200 can be arranged in the cavity 100 or outside the cavity 100 (to lift the freezing rack 110 to the outside of the cavity 100). Other freezing racks or other mechanisms are arranged at the same height of the freezing rack 110. It is inconvenient to take and place biological samples at the same height of the freezing rack 110. It is necessary to use a lifting device to lift the freezing rack 110 before taking and placing the biological samples. Figure 1 The left side is a cross-sectional view when biological samples are not being taken or placed. Figure 2 The right side is a cross-sectional view of taking and placing biological samples. Figure 1 It can be seen that in order to make all biological samples in the freezing rack accessible, a higher reserved space (not less than the height of the freezing rack 110) needs to be set above the freezing rack. The height of the entire biological sample storage device 10 is relatively high, making various operations such as installation, transportation, and maintenance difficult. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiment is one embodiment of the present application, not all embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by persons having ordinary skills in the field to which this application belongs.

[0023] This embodiment provides a biological sample storage device 20, Figure 1 It is a schematic diagram of the principle of taking and placing biological samples in a biological sample storage device in the related art; Figure 2 is a cross-sectional view of some biological sample storage devices 20 provided according to the present embodiment in a first state; Figure 3 is a cross-sectional view of some biological sample storage devices 20 provided according to the present embodiment when they are in a second state; Figure 4 2 is a cross-sectional view of some biological sample storage devices 20 provided according to this embodiment in the third state.

[0024] The biological sample storage device 20 includes a cavity 300 , at least one first freezing rack 400 , at least one second freezing rack 500 , a first lifting device 600 , and a second lifting device 700 .

[0025] The cavity 300 defines a receiving cavity 310; at least one first freezing rack 400 is arranged in the receiving cavity 310, and the first freezing rack 400 is used to store biological samples; at least one second freezing rack 500 is arranged in the receiving cavity 310, and the second freezing rack 500 is used to store biological samples, and the at least one second freezing rack 500 corresponds to the at least one first freezing rack 400 one by one, and each second freezing rack 500 is arranged above the corresponding first freezing rack 400 (it can be understood that it represents a normal storage state rather than a take-and-place state); a first lifting device 600 and a second lifting device 700 are movably arranged along a horizontal plane above the at least one second freezing rack 500 (it can be understood that it represents a normal storage state rather than a take-and-place state), one of the first lifting device 600 and the second lifting device 700 is used to lift the first freezing rack 400, and the other of the first lifting device 600 and the second lifting device 700 is used to lift the second freezing rack 500.

[0026] This biological sample storage device 20 is provided with freezing racks distributed up and down at the same position, and is combined with a first pick-and-place device and a second pick-and-place device, so that there is no need to reserve a higher height space at the same position, the height of the entire biological sample storage device 20 does not need to be too high, and various operations such as installation, transportation, and maintenance are simple.

[0027] like Figure 2 The figure shows a normal storage state. When taking and placing samples in the second freezing rack 500, Figure 3 As shown in FIG. 1 , the second lifting device 700 lifts the second freezing rack 500 so that the biological sample in the second freezing rack 500 can be taken out. Figure 4 As shown, the second lifting device 700 moves horizontally to provide a position for the first lifting device 600, and the first lifting device 600 moves horizontally to the corresponding first freezing rack 400. The first lifting device 600 further lifts the first freezing rack 400 so that the biological sample in the first freezing rack 400 can be taken and placed.

[0028] The first lifting device 600 and the second lifting device 700 may be disposed inside the accommodating chamber 310 or outside the accommodating chamber 310 .

[0029] In some embodiments, the at least one first freezing rack 400 includes a plurality of first freezing racks 400 arranged in a matrix on a horizontal plane, and the at least one second freezing rack 500 includes a plurality of second freezing racks 500 arranged in a matrix on a horizontal plane. Thus, the biological sample storage device 20 has a large storage capacity, a square overall shape, high space utilization, and a wide range of usage scenarios. Moreover, the first freezing rack 400 and the second freezing rack 500 arranged at the same level are not convenient for taking and placing biological samples, and the method of lifting the freezing rack in this embodiment is particularly suitable.

[0030] The height difference between the first freezing rack 400 and the second freezing rack 500 is less than half of the height of the first freezing rack 400 or the second freezing rack 500. Thus, the top reserved space is further reduced. Preferably, the height of the first freezing rack 400 is consistent with the height of the second freezing rack 500.

[0031] In some embodiments, the biological sample storage device 20 is a cold storage, which includes a compression refrigeration system, and the compression refrigeration system is used to provide cold energy to the receiving cavity 310. In other embodiments, the biological sample storage device 20 can also be a freezer, a refrigerator, a storage device including a liquid nitrogen tank, etc.

[0032] The first freezing rack 400 and / or the second freezing rack 500 define at least one rack position, and the rack position is used to store a freezing box, and the freezing box is used to store a biological sample. It can be understood that the freezing box can be provided with a hole position, and the hole position is placed in the freezing tube containing the biological sample, so as to store the biological sample. In other embodiments, the rack position can also directly store the biological sample or store the biological sample through other devices.

[0033] The biological sample storage device 20 also includes a pick-and-place device (understandably, indicating a normal storage state, not a pick-and-place state), which is movably disposed above the at least one second freezing rack 500 in the vertical direction (thereby, the pick-and-place device can pick up and place biological samples at different heights of the first freezing rack 400 or the second freezing rack 500), and the pick-and-place device is used to pick up and place the freezing boxes in the first freezing rack 400 and / or the second freezing rack 500. Specifically, the pick-and-place device may include a shovel, a push rod, a manipulator, etc., and may pick up and place the freezing boxes by adsorption, clamping, support, etc. In other embodiments, the biological sample may also be manually picked up and placed by the user.

[0034] The first lifting device 600, the second lifting device 700 or the pick-and-place device realizes vertical movement through a motor, a cylinder or an electric cylinder, a chain, etc. The specific method of realizing vertical movement by a motor, a cylinder or an electric cylinder is well known to those skilled in the art and will not be repeated here. The first lifting device 600 and the second lifting device 700 can fix or release the first freezing rack 400 or the second freezing rack 500 by hooking, adsorption, clamping, etc.

[0035] The access device can be movably arranged above the at least one second freezing rack 500 along the horizontal plane (understandably, it represents a normal storage state, not an access state). Thus, it is convenient to access and place the biological samples in the first freezing rack 400 or the second freezing rack 500 at different positions on the horizontal plane. Understandably, the access device can also realize the transportation of biological samples, for example, transferring the taken biological samples to the inlet and outlet port of the biological sample storage device 20, etc.

[0036] The first lifting device 600, the second lifting device 700 or the pick-and-place device can realize horizontal movement through guide rails and / or guide grooves. The guide rails, guide grooves, etc. can form a gantry structure. Since such structures for realizing horizontal movement are well known to those skilled in the art, they will not be described in detail here.

[0037] Wherein, the at least one rack is a plurality of racks arranged in a vertical direction, and each rack has a lateral opening. In other embodiments, the at least one rack may also be a plurality of racks arranged in a horizontal direction or in a matrix, and the racks may also have top openings.

[0038] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0039] The above are only specific implementation methods 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 based on the protection scope of the claims.
