[0005] The purpose of this application is to provide an intelligent biological sample transportation device that can prevent the sample container from tilting or tipping over when the sample transport box is tilted or overturned, thus protecting the safety of sample transportation.

[0006] The intelligent biological sample transport device provided in this application adopts the following technical solution:

[0007] A smart biological sample transport device, comprising:

[0008] The outer casing consists of two separable parts, upper and lower.

[0009] The spherical inner liner is set inside the outer casing and consists of two separate parts, which are connected to the two parts of the outer casing respectively.

[0010] A sample holder, rotatably mounted within a spherical inner liner, is used to place and secure sample containers. The center of gravity of the sample holder is lower than the center of the spherical inner liner.

[0015] As a preferred technical solution of this application, the upper support includes a cylindrical upper body and at least one upper support leg connected to the upper end surface of the upper body, with a rolling contact fulcrum located at the end of the upper support leg, and the upper body and the lower body are detachably connected.

[0016] As a preferred technical solution of this application, the upper body is provided with a plurality of sample insertion holes around the axis, the sample insertion holes are arranged opposite to the sample slots to form a space for fixing the sample container, and deformable gaskets are provided on the inner wall of the sample insertion holes.

[0030] The following is combined with Figure 1 -Appendix Figure 4 This application will be described in further detail below.

[0031] Example: This application proposes an intelligent biological sample transport device, referring to... Figure 1-4 The device includes an outer casing 1, a spherical inner liner 2, a sample rack 3, and an environmental control module 4. The outer casing 1 is used to protect the entire device and the safety of the internal samples. The spherical inner liner 2 is located inside the outer casing 1, the sample rack 3 is located inside the spherical inner liner 2, and the environmental control module 4 is located in the space between the inside of the outer casing 1 and the outside of the spherical inner liner 2.

[0032] The outer casing 1 consists of two separable parts, allowing the entire device to be opened for easy placement of sample containers into and removal from the device.

[0033] The spherical inner liner 2 consists of two separate parts, which are connected to the upper and lower parts of the outer casing 1 respectively. The spherical inner liner 2 can be opened, and the interior forms a spherical space for placing sample containers and sample racks 3.

[0034] The sample placement rack 3 rolls in contact with the inner wall of the spherical inner liner 2. The sample placement rack 3 is equipped with a counterweight so that its center of gravity and the center of gravity of the sample container after it is placed are lower than the center of gravity of the spherical inner liner 2. This ensures that if the device tilts or flips, it will return to the upright position of the sample placement rack 3 due to gravity, keeping the sample container upright and preventing sample leakage.

[0035] The environmental control module 4 is installed in the space formed between the outer casing 1 and the spherical inner liner 2. The environmental control module 4 monitors and controls the ambient temperature inside the spherical inner liner 2 to keep it constant.

[0036] In this application, a closed spherical space is formed by using a spherical inner liner 2, and the self-righting principle of the sample placement rack 3 is used to ensure that the sample placement rack 3 can return to an upright position after being tilted in the spherical space, which can effectively protect the sample and ensure the safety of the sample during transportation.

[0037] Furthermore, the outer casing 1 comprises an upper casing 11 and a lower casing 12, forming a rectangular casing. The vertical height of the upper casing 11 is less than that of the lower casing 12. The two sides of the upper casing 11 are connected to the two sides of the lower casing 12 by snap-fit ​​connections, allowing the upper casing 11 to be snapped onto the lower casing 12 from top to bottom, facilitating the opening of the outer casing 1. The outer casing 1 provides the first layer of protection for biological samples.

[0038] Furthermore, the spherical inner liner 2 comprises an upper inner liner 21 and a lower inner liner 22. The upper inner liner 21 is fixedly connected to the upper housing 11, and the lower inner liner 22 is fixedly connected to the lower housing 12. The upper inner liner 21 and the lower inner liner 22 are fastened together to form a closed structure with an internal spherical space. The upper inner liner 21 is partially spherical, and the diameter of its lower opening is smaller than the diameter of the internal spherical space of the spherical inner liner 2. The outer spherical surface of the upper inner liner 21 is fixed to the inner wall of the upper housing 11 by multiple connecting ribs. The lower inner liner 22 is mostly spherical, and the diameter of its upper opening is smaller than the diameter of the internal spherical space of the spherical inner liner 2. The outer spherical surface of the lower inner liner 22 is fixed to the inner wall of the lower housing 12 by multiple connecting ribs.

[0039] In order to improve the tightness and firmness of the connection between the upper inner liner 21 and the lower inner liner 22, strong magnetic blocks are provided at the connection between the upper inner liner 21 and the lower inner liner 22 to improve the connection strength. The spherical inner liner 2 constitutes a second layer of protection for the sample container, and the spherical space inside the spherical inner liner 2 can restrict the movement space of the sample placement rack 3.

[0040] Furthermore, the sample placement rack 3 includes a lower support and an upper support structure, which are connected and fixed by bolts and can be disassembled. At least three rolling contact points 31 are provided between the lower support and the inner wall of the spherical inner liner 2. In this embodiment, four rolling contact points 31 are provided on the lower support for contacting the inner wall of the spherical inner liner 2. The four rolling contact points 31 are not provided on the same straight line or arc curve. At least one rolling contact point 31 is provided between the upper support and the inner wall of the spherical inner liner 2. In this embodiment, one rolling contact point 31 is provided on the upper support for contacting the inner wall of the spherical inner liner 2.

[0041] The lower part of the sample placement rack 3 contacts the inner wall of the spherical inner liner 2 through four rolling contact fulcrums 31, which can ensure the stability of the sample placement rack 3 when placed and prevent the sample placement rack 3 from tilting. The upper part of the sample placement rack 3 contacts the inner wall of the spherical inner liner 2 through one rolling contact fulcrum 31, which can prevent the sample placement rack 3 from bouncing up and down and ensure the stability of the sample placement rack 3.

[0042] The lower support includes a lower base 32, lower support legs 33, and a counterweight 34. The lower base 32 has a cylindrical structure, and several sample slots 35 are evenly arranged around the axis on the upper surface of the lower base 32. The sample slots 35 are circular grooves used to place sample containers. In this embodiment, four lower support legs 33 are provided and fixedly connected to the lower end of the outer peripheral surface of the lower base 32. The axes of the four lower support legs 33 pass perpendicularly through the axis of the lower base 32. The rolling contact fulcrum 31 is located at the end of the lower support leg 33 away from the lower base 32. In this embodiment, the rolling contact fulcrum 31 is set as a metal ball, which rolls and contacts the inner wall of the spherical inner liner 2. The counterweight 34 is a high-density metal block, fixedly connected to the lower surface of the lower base 32, so as to lower the center of gravity of the sample placement rack 3.

[0043] The upper support includes an upper seat 36 and an upper support leg 37. The upper seat 36 is a cylindrical structure with the same diameter as the lower seat 32 and coaxially connected. The upper seat 36 is fixedly connected to the lower seat 32 by bolts. The upper seat 36 has sample insertion holes 38 arranged around its axis, the same number as the number of sample slots 35. The sample insertion holes 38 and sample slots 35 have the same inner diameter and are arranged vertically opposite each other to form a space for fixing the sample container. In order to fix the sample container more firmly, a deformable washer 39 is provided on the inner wall of the sample insertion hole 38. The elastic compression of the washer 39 is used to fix the sample container. At least one upper support leg 37 is connected to the upper seat 36. In this embodiment, the upper support leg 37 is coaxially connected to the upper end face of the upper seat 36. A rolling contact fulcrum 31 is provided at the upper end of the upper support leg 37, so that the upper support leg 37 rolls in contact with the inner wall of the spherical inner liner 2 through the rolling contact fulcrum 31.

[0044] When the entire device tilts, the outer casing 1 and the spherical inner liner 2 will be tilted and remain in a stable state. Because the center of gravity of the sample placement rack 3 is low, it will return to the state where the center of gravity is at the lowest height under the action of gravity, that is, the upper support leg 37 is vertically upward. At this time, both the sample placement rack 3 and the sample container are in an upward state, thereby preventing the sample from leaking out of the sample container.

[0045] Furthermore, the environmental control module 4 includes a temperature sensor, a controller, and a cooling module. The probe of the temperature sensor can extend through the shell of the spherical inner liner 2 into the interior of the spherical inner liner 2. The controller is installed in the space between the outer casing 1 and the spherical inner liner 2. The controller is electrically connected to both the temperature sensor and the cooling module. The cooling module is positioned close to the shell of the spherical inner liner 2 and located in the space between the spherical inner liner 2 and the outer casing 1. In this embodiment, the shell of the spherical inner liner 2 is made of a thermally conductive material. The temperature sensor can monitor the ambient temperature inside the spherical inner liner 2 and transmits the monitoring signal to the controller. The controller is set with a maximum allowable temperature threshold. If the temperature inside the spherical inner liner 2 monitored by the temperature sensor exceeds the maximum temperature threshold, the controller sends a control command to the cooling module, and the cooling module begins cooling to lower the temperature inside the spherical inner liner 2.

[0046] In this embodiment, a battery is also installed inside the outer casing 1 to provide power to the environmental control module 4 to maintain its operation.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
