The placement frame sends a batch of test tubes containing blood to the laboratory for testing.

[0003] For example, in the prior art, the Chinese patent authorization number CN212068848U, application date: 2020-05-09, is a patent entitled "A blood storage device for hospital physical examinations", comprising a box body, a plurality of placement cavities provided in the box body, the inner walls of both sides of the placement cavities being fixedly connected to a splint by a plurality of spring clips, a cover plate being provided on the placement cavities, and a plurality of protective sleeves corresponding to the placement cavities being fixedly connected to the lower side walls of the cover plate.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] Reference Figure 1-Figure 5A blood storage device includes a storage box 1, a matching connecting cover 2 is installed on the top of the storage box 1, a storage cavity 3 is opened on the top of the storage cavity 3, a concave plate 4 is slidably connected to the inside of the storage cavity 3, and a clamping mechanism 5 is provided at the bottom of the concave plate 4; wherein the clamping mechanism 5 includes a piston assembly 51 fixed between the storage cavity 3 and the concave plate 4, one side of the piston assembly 51 is connected to a connecting air pipe 52, the inner wall of the storage cavity 3 is opened with a T-slot 54, the inside of the T-slot 54 is installed with an expansion air bag 53, and the end of the connecting air pipe 52 is connected to the inside of the expansion air bag 53.

[0027] In the present invention, when the test tubes carrying blood are installed, the storage cavity 3 opened on the top of the storage box 1 is set, so that the test tubes carrying blood can be placed in the storage cavity 3 in sequence. When the bottom of the test tube carrying blood contacts the surface of the concave plate 4, the concave plate 4 presses the clamping mechanism 5 by the weight of the test tube carrying blood. Under the pressure of the clamping mechanism 5, the test tube carrying blood can be initially limited. Then, the connecting cover 2 is installed on the top of the storage box 1, and the top of the test tube carrying blood in the storage cavity 3 can be squeezed again, so that the storage cavity 3 moves downward. When the piston assembly 51 moves downward, the air inside the piston assembly 51 can be transported to the inside of the expansion airbag 53 through the connecting air pipe 52 for expansion, thereby limiting and clamping the test tube carrying blood. Under the action of the T-slot 54, the expansion airbag 53 can be guided and limited. When the connecting cover 2 and the storage box 1 are closed, pressure can be applied to the top of the test tube carrying blood again, so that it can be firmly clamped on the surface of the test tube carrying blood.

[0028] It is additionally explained that the test tube carrying blood is made of glass and has a certain hardness, so that even after the inflation airbag 53 is fully inflated, the test tube carrying blood will not be clamped and cause rupture, thereby ensuring safety during clamping.

[0029] Reference Figure 2 A guide groove 6 is provided on the top of the connecting cover 2 , and a pressing spring 7 is fixedly connected to the inner top wall of the guide groove 6 . A pressing plate 8 is fixedly connected to the end of the pressing spring 7 , and the pressing plate 8 slides inside the guide groove 6 .

[0030] In the present invention, with the guide groove 6 opened, the pressing spring 7 can be installed, and then the pressing plate 8 can be installed through the pressing spring 7, so that when the storage box 1 and the connecting cover 2 are closed, the pressing plate 8 can be installed on the top of the test tube carrying blood to limit the position, thereby ensuring the stability of the test tube carrying blood.

[0031] Reference Figure 2 The connecting cover 2 and the top of the pressing plate 8 are both provided with vent holes 9, and the connecting cover 2 and the vent holes 9 opened on the top of the vent holes 9 are in the same straight line.

[0032] In the present invention, the vent holes 9 opened on the top of the connecting cover 2 and the pressing plate 8 facilitate the circulation of air in the storage box 1, thereby preventing the temperature in the storage box 1 from rising due to the closure being too tight, thereby affecting the activity of the blood.

[0033] Reference Figure 3 The piston assembly 51 includes a piston cylinder 511 fixed to the bottom wall of the storage chamber 3. The interior of the piston assembly 51 is slidably connected to a piston rod 512, and the end of the piston rod 512 is fixedly connected to the concave disk 4.

[0034] In the present invention, the piston rod 512 is arranged inside the piston cylinder 511 so that when a test tube carrying blood is installed above the concave disk 4, the weight of the test tube carrying blood can press the piston rod 512 to displace the concave disk 4. The piston rod 512 slides inside the piston cylinder 511, so that the gas inside the piston cylinder 511 can be compressed and enter the expansion airbag 53 to expand, thereby clamping and fixing the surface of the test tube carrying blood.

[0035] Reference Figure 3 The surface of the piston rod 512 is sleeved with a support spring 513, and the two ends of the support spring 513 are fixedly connected to the piston cylinder 511 and the concave disk 4 respectively.

[0036] In the present invention, the support spring 513 sleeved on the surface of the piston rod 512 exerts a reaction force between the concave plate 4 and the piston cylinder 511, thereby exerting a force on the concave plate 4.

[0037] Reference Figure 4 and Figure 5 Both sides of the storage box 1 are fixedly connected with buckles 10, and both sides of the connecting cover 2 are fixedly connected with card blocks 11, and the buckles 10 and the card blocks 11 can be snap-connected.

[0038] In the present invention, the buckles 10 on both sides of the storage box 1 are arranged so that the buckles 10 can be engaged with the fixed blocks 11 on both sides of the connecting cover 2, thereby completing the locking effect between the storage box 1 and the connecting cover 2.

[0039] Reference Figure 3 The shape of the expansion airbag 53 is T-shaped, and the expansion area of ​​the expansion airbag 53 is in a corrugated configuration.

[0040] In the present invention, the expansion airbag 53 is T-shaped so that it can only expand toward the middle position, thereby completing the clamping and fixing of the test tube carrying blood, and the expansion area of ​​the expansion airbag 53 is corrugated so that it can be stretched and expanded to a large extent.

[0041] Reference Figure 1 The number of storage cavities 3 and guide grooves 6 are both arranged in multiple groups, and the multiple guide grooves 6 are all located directly above the multiple groups of storage cavities 3.

[0042] In the present invention, the storage chamber 3 and the guide groove 6 are arranged in multiple groups, so that multiple groups of test tubes carrying blood can be installed at the same time, and because the multiple guide grooves 6 are located directly above the multiple groups of storage chambers 3, sufficient space can be provided for storing the test tubes carrying blood.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
