[0026] Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments can be combined with each other in the case of no conflict.
[0027] Embodiments
[0028] Referring to Figure 1 The present embodiment provides a biological sample storage device 100 for storing genetic detection samples or other types of biological samples 300.
[0029] In this embodiment, the biological sample storage device 100 comprises a storage cabinet 110 and a transfer device 120.
[0030] The storage cabinet 110 has an internal space Q1 for accommodating biological samples 300. In one embodiment, the storage cabinet 110 is an ultra-low temperature freezer, and the internal space Q1 comprises an ultra-low temperature storage area Q11, a tube picking mechanical area Q12, and an operation area Q13, etc. The set temperature of the ultra-low temperature storage area Q11 is lower than that of the tube picking mechanical area Q12, and the set temperature of the tube picking mechanical area Q12 is lower than that of the operation area Q13. The areas with different temperatures are used to store biological samples 300 with different storage temperature requirements, or to realize different functions. Adjacent areas can be connected through a sample transfer window, and the sample transfer window can be opened when biological samples 300 need to be transferred between different areas.
[0031] The transfer device 120 is arranged in the internal space Q1 and is used to transfer target objects such as biological samples 300 between the ultra-low temperature storage area Q11, the tube picking mechanical area Q12, and the operation area Q13. The biological samples 300 can be accommodated in sample boxes.
[0032] In some embodiments, the biological sample storage device 100 can realize automatic access, tube picking, and sample information management of samples through the transfer device 120 and some automatic structures arranged in the biological sample storage device 100. Compared with existing biological sample freezers, the biological sample storage device 100 of this embodiment is more flexible in deployment and use.
[0033] The following will be described in conjunction with Figures 2-4 to exemplarily introduce the transfer device 120 of this embodiment.
[0034] Referring to Figure 2 , this embodiment provides a transfer device 120, which comprises a base 10, a tray 20, and two elastic members 30. The tray 20 is slidably supported on the base 10 and is used to carry biological samples 300. The elastic members 30 are elastically supported between the base 10 and the tray 20 and are used to provide buffering between the tray 20 and the base 10.
[0035] Referring mainly to Figure 3 , the base 10 comprises a seat plate 11 and a first limiting portion 12. The first limiting portion 12 is a block structure protruding from the upper surface of the seat plate 11. The first limiting portion 12 can be integrally formed with the seat plate 11, or can be connected to the seat plate 11 by screws, adhesion, welding, clamping, or other forms, and the specific connection form is not limited herein. The shape of the first limiting portion 12 can be square, circular, or other shapes.
[0036] The tray 20 is provided with a strip-shaped slot C1 extending along the first direction Y1, and the tray 20 has two second limiting portions 22 respectively located at both ends of the strip-shaped slot C1 along the first direction Y1. The two second limiting portions 22 can be the same or different in shape.
[0037] With reference to Figure 3 and Figure 4 In the assembled state, the first limiting portion 12 passes through the strip-shaped slot C1 along the thickness direction of the tray 20 and is located between the two second limiting portions 22.
[0038] The two elastic members 30 are respectively elastically supported between the first limiting portion 12 and the two second limiting portions 22, thereby providing elastic damping for the movement of the tray 20 relative to the base 10 along the first direction Y1 and buffering the relative movement of the tray 20 relative to the base 10.
[0039] For example, when the transfer device 120 moves normally, the tray 20 and the base 10 can remain relatively stationary and move synchronously under the support of the elastic force of the elastic member 30. When the tray 20 accidentally collides with an obstacle due to inaccurate positioning or other reasons, the elastic member 30 can provide elastic buffering for the collision, thereby reducing the safety hazards such as collision damage and sample damage.
[0040] The elastic member 30 in the embodiment can be a coil spring, or a spring sheet, an elastic pad, etc., which is not limited herein.
[0041] The elastic member 30 can be pre-compressed between the first limiting portion 12 and the second limiting portion 22, that is, in the initial state, the elastic member 30 provides a certain elastic force to the first limiting portion 12 and the second limiting portion 22 to overcome the inertia of the tray 20, thereby limiting the relative movement of the tray 20 relative to the base 10 to a certain extent and ensuring the normal taking and placing function of the biological sample 300. The two elastic members 30 can be springs of the same size, and in the assembled state, both are compressed equally.
[0042] In the embodiment, the surface of the side of the tray 20 away from the base 10 is defined as the first surface P1. The first limiting portion 12 and the two second limiting portions 22 protrude from the first surface P1, and the two elastic members 30 are respectively supported on the portions of the first limiting portion 12 and the second limiting portion 22 protruding from the first surface P1.
[0043] Again with reference to Figure 4 In the embodiment, the transfer device 120 can further include a detection element 40 provided on the tray 20 and used for detecting the displacement and direction of the tray 20 relative to the base 10 and other position information. The detection element 40 can be mounted on the first surface P1 of the tray 20.
[0044] The detection element 40 can be a proximity sensor, a photoelectric sensor, or other types of sensors, which are not limited herein.
[0045] In this embodiment, the detection element 40 is two, and the two detection elements 40 are located on both sides of the first limiting portion 12 along the first direction Y1. And the two detection elements 40 are respectively located on both sides of the width direction of the strip-shaped groove C1. Among them, the width direction of the strip-shaped groove C1 is defined as the second direction Y2, which is perpendicular to the first direction Y1 and parallel to the plate surface of the tray 20. The position arrangement of the detection element 40 of this embodiment is reasonable, which can accurately detect the motion displacement and direction of the tray 20.
[0046] Optionally, the detection element 40 can also be electrically connected with an upper computer (such as a control computer). In this way, when the detection element 40 detects that the displacement of the tray 20 relative to the base 10 exceeds the allowable value, the detection element 40 can send an alarm signal to the upper computer. After the upper computer receives the alarm signal, it can remind the relevant personnel through sound, screen display or other ways, or it can stop the operation of the transfer device 120 after receiving the alarm signal to ensure the safety in use.
[0047] Again referring to Figure 1 and Figure 2 , in this embodiment, the tray 20 further comprises a carrying portion 21, which extends out of the base 10 along the first direction Y1 and is used for carrying target pieces (such as biological samples 300). The carrying portion 21 has a second surface P2, which is concave relative to the first surface P1 to facilitate the cooperation with the biological samples 300.
[0048] In one embodiment, the transfer device 120 further comprises a driving assembly 50, which is drivingly connected with the base 10 and is used for driving the base 10 to move along the first direction Y1. When the transfer device 120 is normally operated, the tray 20 can move synchronously or substantially synchronously with the base 10.
[0049] The driving assembly 50 can be a linear motor, a linear cylinder, or a combination of a rotary driver (such as a rotary motor) and a screw nut mechanism, as long as it can output linear motion.
[0050] In this embodiment, the transfer device 120 further comprises a sliding rail 60, which extends along the first direction Y1, and the base 10 is slidably supported on the sliding rail 60 along the first direction Y1. In this way, when needed, the driving assembly 50 can drive the tray 20 and the base 10 to slide together along the sliding rail 60.
[0051] The present application also provides an embodiment, which is relative Figures 2-4In the shown embodiment, the setting positions of the first limiting part 12 and the second limiting part 22 are as follows: the first limiting part 12 is arranged on the tray 20, and the strip-shaped slot C1 and the two second limiting parts 22 are arranged on the base 10. This embodiment can also buffer the collision of the tray 20.
[0052] In summary, the transport device 120 of the embodiments of the present application can safely and reliably realize the transport of the biological sample 300, and is safe and convenient to use.
[0053] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the present application.
