[0038] Example 1, combined Figures 1 to 7 As shown, this embodiment provides a test tube ice water bath device, comprising a container 5, a container 4 sleeved on the container 5 and having a receiving cavity, and a connecting assembly 1 for connecting the container 4 to the container 5. The test tube is placed in the receiving cavity of the container 4. The container 5 forms a limiting groove 56. The connecting assembly 1 is provided with a limiting member corresponding to the limiting groove 56. The container 4 cooperates with the limiting member to achieve a locking connection with the container 5. Ice water is added to the container 5, and the container 4 is clamped between the container 5 and the connecting assembly 1 through the cooperation of the limiting member and the limiting groove 56. The test tube containing blood is placed in the receiving cavity of the container 4, realizing the refrigerated transportation function of a single test tube, with a small volume and convenient and low-cost transportation.

[0039] In this embodiment, the container 4 is constructed from a composite material. This composite material is made from elastic silicone with thermally conductive fillers (such as metal powder or graphene) added to improve its thermal conductivity. This ensures that the silicone completely encapsulates the test tube while also meeting thermal conductivity requirements, allowing heat from the ice water to be transferred to the test tube, ensuring the tube remains at a low temperature during transportation.

[0040] In this embodiment, container 5 is made of a transparent material (glass or polymethyl methacrylate) and has a liquid flow chamber 54 for holding liquid, and a liquid inlet 52 and a liquid outlet 53 respectively connected to liquid flow chamber 54. Both inlet 52 and outlet 53 are provided with screw-on caps 6. The inlet 52 can be filled with ice water. After transport, the liquid in container 5 can flow out through outlet 53, ensuring that container 5 can be reused. The bottom of container 5 is formed with a slope 55, with the lowest point of slope 55 tilted toward outlet 53. This allows liquid at the bottom of container 5 to flow out smoothly from outlet 53, preventing liquid accumulation at the bottom of container 5. Container 5 is provided with graduated markings 51, which facilitate monitoring of the liquid level.

[0041] Specifically, the connection assembly 1 includes two oppositely disposed first and second connection members 11, 12. The stoppers are respectively disposed on the first and second connection members 11, 12. The first and second connection members 11, 12 are locked together by a locking member 3. The first and second connection members 11, 12 are both semicircular structures with hollow cavities, which communicate with the accommodating cavity of the accommodating member 4, allowing a test tube to pass through the hollow cavities and then be inserted into the accommodating cavity of the accommodating member 4. The limiting member includes a first limiting protrusion 113 and a second limiting protrusion 123. The first limiting protrusion 113 and the second limiting protrusion 123 have the same structure. The first limiting protrusion 113 and the second limiting protrusion 123 are respectively arranged on the first connecting member 11 and the second connecting member 12. The first limiting protrusion 113 and the second limiting protrusion 123 are both plugged into the limiting groove 56. The edge of the accommodating member 4 is placed between the first limiting protrusion 113 and the limiting groove 56, and the second limiting protrusion 123 and the limiting groove 56, and is squeezed by the first limiting protrusion 113 and the limiting groove 56, and the second limiting protrusion 123 and the limiting groove 56. The first connecting member 11 and the second connecting member 12 are then locked by the locking member 3, so that the accommodating member 4 is connected to the container 5 through the connecting assembly 1.

[0042] In this embodiment, the first limiting ring 112 and the second limiting ring 122 are respectively provided on the first connecting member 11 and the second limiting ring 122. The first limiting ring 112 and the second limiting ring 122 are both semi-annular structures. The first limiting protrusion 113 and the second limiting protrusion 123 are respectively provided on the inner walls on the opposite side of the first limiting ring 112 and the second limiting ring 122. The first limiting ring 112 and the second limiting ring 122 can play the role of clamping the accommodating member 4.

[0043] Specifically, the locking member 3 includes a locking bolt and a locking nut. The first connecting member 11 and the second connecting member 12 are respectively provided with a fixing seat corresponding to the locking bolt. The locking bolt cooperates with the locking nut to lock and connect the fixing seats of the first connecting member 11 and the second connecting member 12. The fixing seat is provided at the opposite ends of the first connecting member 11 and the second connecting member 12 and is formed with a threaded hole. The locking bolt is threadedly engaged with the threaded hole. When the locking nut cooperates with the locking bolt, the locking nut is abutted against the fixing seat, thereby achieving a locked connection between the first connecting member 11 and the second connecting member 12.

[0044] Specifically, when transporting multiple blood samples, multiple devices can be combined and spliced. The first connector 11 includes a first connecting plate 111 and a connecting block 114 provided on the first connecting plate 111; the second connector 12 includes a second connecting plate 121 and a connecting groove 124 provided on the second connecting plate 121. The connecting block 114 and the connecting groove 124 can be plugged in and matched. The shapes of the connecting block 114 and the connecting groove 124 match. In this embodiment, the connecting block 114 and the connecting groove 124 are parallelogram structures that can be plugged in and matched, which can ensure the longitudinal and lateral limiting functions of the first connector 11 and the second connector 12. By plugging in and matching two adjacent connecting blocks 114 and the connecting groove 124, the connection between the two adjacent first connectors 11 and the second connector 12 is realized, thereby realizing the refrigerated transportation operation of multiple devices.

[0045] In this embodiment, a locking rod 116 is provided on the first connecting plate 111, and a locking buckle 126 is provided on the second connecting plate 121. The locking buckle 126 is movably provided on the second connecting plate 121, and the locking rod 116 and the locking buckle 126 can be cooperatively connected. The locking buckle 126 has an open slot 126a and a landing hole 126b that are interconnected, corresponding to the locking rod 116. The locking buckle 126 is made of elastic material, and the opening width of the open slot 126a is smaller than the diameter of the locking rod 116. The locking rod 116 includes a connecting shaft and a shaft cap axially provided at the end of the connecting shaft. The shaft cap can be supported on the locking buckle 126. When in use, the locking rod 116 enters the landing hole 126b through the open slot 126a and cooperates with the landing hole 126b to further improve the connection stability between the two adjacent devices.

[0046] Specifically, the test tube ice-water bath device also includes a locking assembly 2, which is disposed on the connecting assembly 1. Two sets of locking assemblies 2 are provided, one on the first connecting member 11 and the other on the second connecting member 12. The locking assembly 2 includes a control threaded rod 22 threadedly connected to the connecting assembly 1, and a positioning clamping sleeve 25 rotatably connected to the control threaded rod 22. Rotating the control threaded rod 22 drives the positioning clamping sleeve 25 toward the test tube, thereby confining the test tube within the accommodating member 4. The first connecting member 11 and the second connecting member 12 are respectively provided with a first support 115 and a second support 125. The first support 115 and the second support 125 each have a threaded hole. The control threaded rod 22 is threadedly connected to the threaded hole. The rod end of the control threaded rod 22 passes through the threaded hole and is rotatably connected to the positioning clamping sleeve 25, thereby enabling the control threaded rod 22 to push the positioning clamping sleeve 25 toward the test tube, thereby clamping the test tube.

[0047] In this embodiment, a rotating block 24 is provided at the rod end of the control threaded rod 22 , and a rotating groove is formed in the positioning clamping sleeve 25 corresponding to the rotating block 24 . The rotating block 24 is disposed in the rotating groove and can be rotatably connected thereto.

[0048] Specifically, a rubber sleeve pad 26 is provided on the positioning clamping sleeve 25, and the rubber sleeve pad 26 contacts the outer circumferential surface of the test tube. The rubber sleeve pad 26 can increase the friction with the test tube and also play a role of buffering and shock absorption.

[0049] Specifically, a spring 23 is sleeved on the control threaded rod 22, and both ends of the spring 23 respectively abut against the positioning clamping sleeve 25 and the first pillar 115 and the second pillar 125. The force of the spring 23 can enable the positioning clamping sleeve 25 to clamp the test tube more stably.

[0050] Specifically, a rotating wheel 21 is axially mounted on the end of the control threaded rod 22. The rotating wheel 21 cooperates with the first and second struts 115, 125 to limit the movement of the control threaded rod 22. When the positioning clamping sleeve 25 moves to a certain distance, the rotating wheel 21 abuts against the end surfaces of the first and second struts 115, 125, preventing the control threaded rod 22 from slipping out of the first and second struts 115, 125, thereby limiting the position of the control threaded rod 22.

[0051] Specifically, the positioning clamping sleeve 25 is provided with a limiting rod 27, which is respectively mounted on the first support 115 and the second support 125. The limiting rod 27 can effectively enhance the connection stability between the positioning clamping sleeve 25 and the first support 115 and the second support 125. Preferably, two limiting rods 27 are provided, and the two limiting rods 27 are arranged side by side and located at the left and right ends of the positioning clamping sleeve 25, which can further enhance the connection stability between the positioning clamping sleeve 25 and the first support 115 and the second support 125.

[0052] In this embodiment, combined with Figure 1 、 Figure 7 As shown, when a single blood specimen needs to be transported, the container 4 is first placed over the outer edge of the opening of the container 5. The first and second limiting protrusions 113, 123 engage with the limiting groove 56, so that the outer edge of the container 4 is clamped between the first and second limiting protrusions 113, 123, and the limiting groove 56, respectively. The locking member 3 is then used to connect the fixing seats of the first and second connecting members 11, 12, respectively, so that the container 4 is connected to the container 5 through the connecting assembly 1. The test tube is vertically inserted into the receiving cavity of the container 4. The operator holds the rotating wheel 21, drives the control threaded rod 22 to push the positioning clamping sleeve 25 to move toward the test tube, thereby clamping the test tube. Ice water is then injected into the liquid flow chamber 54 of the container 5 through the liquid inlet 52, and the liquid level is observed according to the scale mark 51 to determine whether it is qualified.

[0053] When multiple blood specimens need to be transported, the connecting block 114 between two adjacent devices is plugged into the connecting groove 124, and the locking rod 116 enters the overlapping hole 126b through the opening groove 126a and is connected with the overlapping hole 126b to realize the connection between the first connecting member 11 and the second connecting member 12 of the two adjacent devices, thereby realizing the connection between multiple devices and further realizing the refrigerated transportation operation of multiple blood specimens.
