Description

Technical Field

[0001] This utility model relates to the field of blood matrix sample storage technology, and in particular to a cold air settling dry ice sorting operation table. Background Technology

[0002] In pharmaceutical research and development, strict requirements are placed on the preservation conditions of biological samples, especially blood matrix samples, which are particularly sensitive to temperature changes and need to be stored in an ultra-low temperature environment to avoid adverse events such as melting, deterioration, and reduced activity, and to ensure the stability and activity of the biological samples as analytes.

[0003] Currently, dry ice (solid carbon dioxide, with a temperature of -60℃ to -90℃, consistent with the normal storage temperature of samples) is commonly used in laboratory operations to create an ultra-low temperature environment. Existing experimental platforms only use containers to place dry ice at the bottom of the sample, while the upper surface of the sample is close to room temperature, which cannot guarantee the stability and activity of the sample analyte.

This utility model efficiently constructs and stably maintains the ultra-low temperature environment required for samples through the design of the upper and lower placement boxes and the circular hole. Combined with baffles and heat insulation pads, it reduces the diffusion of cold air and ensures personnel safety. The handles on the operating platform and the adjustable U-shaped frame make it more convenient to replace dry ice and carry out daily operations.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Refer to Figure 1-4A cold air settling dry ice sorting operating table includes a support frame 1, an operating table frame 2 fixedly connected to the support frame 1, an upper placement box 3 and a lower placement box 201 respectively provided on the upper and lower sides of the operating table frame 2, the upper placement box 3 and the lower placement box 201 are used to place dry ice, the upper placement box 3 and the lower placement box 201 are fixedly connected to the support frame 1, an operating table plate 202 is installed on the lower placement box 201, the upper placement box 3 is provided with an upper cover plate 301, and the lower end of the upper placement box 3 is provided with a round hole 302 with a diameter of 3-5mm;

[0024] The operating platform 2 can be cooled by the upper placement box 3 and the lower placement box 201. Specifically, the round hole 302 at the bottom of the upper placement box 3 can utilize the principle that dry ice is easy to volatilize and cold air is easy to settle to provide the ultra-low temperature environment required around the sample and seal the outside, which is beneficial for heat preservation.

[0025] The removable operating platform 202 and the top cover 301 facilitate the replacement of dry ice.

[0026] The control panel 202 is equipped with handles at its four corners for easy operation and lifting.

[0027] A U-shaped frame 4 is fixedly installed on the support frame 1. The U-shaped frame 4 is used to place the upper cover plate 301. The spacing of the U-shaped frame 4 can be adjusted according to the size of the upper cover plate 301.

[0028] A baffle 101 is installed on the support frame 1. The baffle 101 is used to enclose the support frame 1 to form an opening on one side. A heat insulation pad is provided on the side of the baffle 101 near the operating table 202 to prevent the cold air of dry ice from spreading and to protect personnel safety.

[0029] The bottom of the support frame 1 is equipped with a support leg 102.

[0030] When using the cold air settling dry ice sorting workbench, first prepare for operation by ensuring that the support legs 102 are stable, the baffle 101 and the heat insulation pad are intact, adjust the spacing of the U-shaped frame 4 and put the relevant parts back in place; then load the dry ice by moving the upper cover plate 301 to the U-shaped frame 4, removing the workbench plate 202, adding dry ice to the upper placement box 3 and the lower placement box 201, and then putting the workbench plate 202 and the upper cover plate 301 back in place; then carry out sample handling by placing the sample through the opening of the baffle 101, using the cold air from the dry ice settling through the round hole 302 of the upper placement box 3 and the cold air from the lower placement box 201 to create an ultra-low temperature environment, and using the baffle 101 and the heat insulation pad for insulation, and processing the sample on the opening side; when the low temperature environment does not meet the requirements, it is determined that the dry ice needs to be replaced and the dry ice loading steps are repeated.

[0031] At the end of the operation, transfer the sample, clean the surface of the equipment and the residue inside the chamber, and finally reset all components to complete the entire operation process.

[0032] This utility model efficiently constructs and stably maintains the ultra-low temperature environment required for samples through the design of the upper placement box 3, the lower placement box 201, and the circular hole 302. Combined with the baffle 101 and the heat insulation pad, it reduces the diffusion of cold air and ensures personnel safety. The handle of the operating platform 202 and the adjustable U-shaped frame 4 make the replacement of dry ice and daily operation more convenient. In addition, the sturdy support legs 102 and the highly adaptable structure not only reduce dry ice consumption and improve operating efficiency, but also adapt to various sample processing scenarios, combining practicality, safety and convenience.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
