DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all.

[0030] Please refer to Figures 1-12 A blood sample cooling transport device, including the main body of the transport box 1, the ice bag 3 is placed in one end inside the main body of the transport box 1, the test tube rack 2 is placed in the other end inside the main body of the transport box 1, the ice bag 3 and the test tube rack 2 support are provided with the partition 101 which is fixedly connected with the main body of the transport box 1, the outer side of the ice bag 3 is distributed with the annularly arranged cooling pipe 13, the cooling pipe 13 is located inside the partition 101 and the main body of the transport box 1 close to the ice bag 3 one end, the micro water pump 7 is fixedly connected with the water inlet pipe 9 which is in communication therewith at the water inlet end of the micro water pump 7, the other end of the water inlet pipe 9 is in communication with the cooling pipe 13, the water outlet pipe 8 which is in communication with the water outlet end of the micro water pump 7 is fixedly connected therewith, the positioning groove 17 is arranged on both sides of the test tube rack 2 close to the ice bag 3 one end, the positioning pipe 10 is slidingly connected inside the two positioning grooves 17, and the opening and closing assembly is rotatably connected inside the positioning pipe 10, the lower end of one of the positioning pipes 10 is in communication with the water outlet pipe 8, the lower end of the other positioning pipe 10 is in communication with the cooling pipe 13, the test tube groove 202 is arranged at the upper end of the test tube rack 2, the cooling cavity 201 which is in communication with the positioning groove 17 is arranged inside the test tube rack 2, the battery 6 is fixedly connected to the bottom of the main body of the transport box 1, the temperature display screen 4 is fixedly connected to the outer wall of the main body of the transport box 1, and the time control switch 5 is fixedly connected to one side of the temperature display screen 4.

[0031] The blood sample cooling transportation device in the application, when the blood sample is placed in the transportation box body 1, only needs to place the test tube containing the blood sample in the test tube groove 202 on the top of the test tube rack 2, align the positioning groove 17 at the end of the test tube rack 2 with the positioning tube 10, then move the test tube rack 2 downward, and insert the positioning tube 10 into the positioning groove 17, then rotate the opening and closing assembly, so that the two ends of the cooling cavity 201 are respectively connected with the water outlet pipe 8 and the water inlet pipe 9, and the miniature water pump 7 is started through the time control switch 5, so that the miniature water pump 7 works for a period of time, and in this period of time, the cooling liquid in the cooling pipe 13 circulates in the cooling pipe 13, the miniature water pump 7 and the cooling cavity 201, so that the test tube rack 2 and the blood sample on the test tube rack 2 are rapidly cooled and uniformly cooled, so as to improve the preservation effect. Since the cooling pipe 13 is around the ice bag 3, the cooling liquid in the cooling pipe 13 has a low temperature, which is beneficial to improve the cooling speed, and the temperature display screen 4 can display the temperature in the transportation box body 1 in real time, so as to conveniently adjust the number of ice bags 3. The positioning tube 10 not only can play the role of conveying the cooling liquid, but also can play the role of positioning, so that the test tube rack 2 is more stable when placed in the transportation box body 1. At the same time, the miniature water pump 7 is powered by the storage battery 6 and controlled by the time control switch 5. After the time control switch 5 is pressed, the miniature water pump 7 can stop working after a period of time. In this way, the energy consumption can be reduced, and the temperature in the transportation box body 1 can be quickly reduced to a suitable range. Since the temperature display screen 4, the time control switch 5, the storage battery 6 and the miniature water pump 7 are all products of existing mature technology, detailed description is not given here. In addition, the structure of the transportation box body 1 in the application is similar to the structure of the peripheral blood sample preservation and transportation device disclosed in the patent with the patent publication number CN216917059U, so no more elaboration is given here.

[0032] As a preferred technical scheme of the application, the opening and closing assembly comprises a water injection pipe 11 and a knob 12, the lower end and the upper end of the side wall of the positioning tube 10 are respectively provided with a lower end water inlet groove 19 and an upper end water inlet groove 20, the lower end and the upper end of the water injection pipe 11 are respectively provided with a water outlet groove 23, the two water outlet grooves 23 correspond to the lower end water inlet groove 19 and the upper end water inlet groove 20 respectively, the area of the lower end water inlet groove 19 is not less than twice the area of the upper end water inlet groove 20, the right side walls of the lower end water inlet groove 19 and the upper end water inlet groove 20 are located on the same vertical plane, and the top of the water injection pipe 11 is fixedly connected with the knob 12.

[0033] Specifically, if only one test tube rack 2 is placed inside the transport box main body 1 (i.e. one test tube rack 2 is inserted on the positioning tube 10), at this time, the outflow grooves 23 at the lower end are made to coincide with the inflow grooves 19 at the lower end by rotating the knob 12 by a certain angle (the angle is equal to the included angle between the left side wall of the outflow groove 23 and the left side wall of the inflow groove 19 at the lower end), but the outflow grooves 23 at the upper end are not made to coincide with the inflow grooves 20 at the upper end, at this time, the cooling cavities 201 inside the test tube rack 2 are connected with the outflow pipe 8 and the inflow pipe 9, if two test tube racks 2 are placed inside the transport box main body 1, at this time, the outflow grooves 23 at the upper end are made to coincide with the inflow grooves 20 at the upper end by rotating the knob 12 by a certain angle (the angle is equal to the included angle between the left side wall of the outflow groove 23 and the left side wall of the inflow groove 20 at the upper end), that is, the cooling cavities 201 inside the two test tube racks 2 are simultaneously connected with the outflow pipe 8 and the inflow pipe 9, so that a micro water pump 7 can drive the cooling liquid inside the two test tube racks 2 to flow simultaneously.

[0034] As a preferred technical solution of the present application, the lower end of the inner wall of the positioning tube 10 is fixedly connected with a lower end limiting ring 21, the upper end of the inner wall of the positioning tube 10 is fixedly connected with an upper end limiting ring 22, the outer wall of the water injection pipe 11 is provided with a lower end limiting groove 24 matched with the lower end limiting ring 21 at the lower end, and the outer wall of the water injection pipe 11 is provided with an upper end limiting groove 25 matched with the upper end limiting ring 22 at the upper end.

[0035] Specifically, the water injection pipe 11 is limited by the lower end limiting ring 21 and the upper end limiting ring 22 to avoid being separated from the top of the positioning tube 10.

[0036] As a preferred technical solution of the present application, the top of the knob 12 is provided with a pointing groove 26, which is provided in the form of an arrow.

[0037] Specifically, the direction of the water outlet groove 23 is indicated by the indicating groove 26, which facilitates the user to determine whether the water outlet groove 23 coincides with the corresponding water inlet groove. For example, as the included angle between the left and right side walls of the water outlet groove 23 is 90°, the included angle between the left and right side walls of the lower end water inlet groove 19 is 180°, and the included angle between the left and right side walls of the upper end water inlet groove 20 is 90°, and the opening direction of the lower end water inlet groove 19 is towards the right end of the transport box body 1, when the arrow direction of the indicating groove 26 is towards the right end, the water outlet groove 23 at the lower end of the water injection pipe 11 coincides with the lower end water inlet groove 19, but the water outlet groove 23 at the upper end of the water injection pipe 11 does not coincide with the upper end water inlet groove 20. In order to make the water outlet groove 23 at the upper end of the water injection pipe 11 coincide with the upper end water inlet groove 20, the arrow direction of the indicating groove 26 needs to be towards the rear side of the transport box body 1 by rotating the knob 12. When the arrow direction of the indicating groove 26 is towards other directions, the two water outlet grooves 23 do not coincide with the lower end water inlet groove 19 and the upper end water inlet groove 20.

[0038] As a preferred technical solution of the present application, the cooling cavity 201 is S-shaped, and a plurality of elastic tabs 18 are fixed to the inner wall of the positioning groove 17 at the lower end of the transport box body 1.

[0039] Specifically, the S-shaped cooling cavity 201 guides the flow direction of the cooling liquid, facilitating the cooling liquid to rapidly cool the blood sample in the test tube groove 202. Meanwhile, the elastic tabs 18 play a sealing role to prevent the cooling liquid in the cooling cavity 201 from flowing out from the lower end of the positioning groove 17.

[0040] As a preferred technical solution of the present application, the bottom of the test tube rack 2 is provided with connecting grooves 15 on both sides away from the positioning groove 17, and connecting columns 16 are fixed to the top of the test tube rack 2 on both sides close to the connecting grooves 15, and the connecting columns 16 are matched with the connecting grooves 15.

[0041] Specifically, when the test tube racks 2 are stacked, the connecting columns 16 on the lower test tube rack 2 are inserted into the connecting grooves 15 on the upper test tube rack 2, so that the test tube racks 2 are more stable when stacked.

[0042] As a preferred technical solution of the present application, the bottom of the test tube rack 2 is provided with a placing groove 14. The placing groove 14 can prevent the upper test tube rack 2 from pressing the test tube containing the blood sample, thereby preventing the test tube from being damaged.

[0043] Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the application.
