Vacuum suction storage forensic extract refrigerating box

Abstract

The invention relates to the technical field of medical refrigerating boxes, in particular to a vacuum suction storage forensic extract refrigerating box. The forensic extract refrigerating box comprises a refrigerating box shell and a storage box mounted in the refrigerating box shell, the storage box internally comprises a plurality of partition boxes, a storage cavity is formed in the surface of the side wall of each partition box, and a communicating air hole is formed in the center of the inner wall of each storage cavity; and a connecting pipe is arranged at the position, located at the edge of the communicating air hole, of the inner wall of the storage cavity, an air conveying pipe is installed on the communicating air hole in a threaded manner, a vacuum pipeline is installed at one end of the air conveying pipe in a threaded manner, an electromagnetic valve used for controlling connection and disconnection of the pipeline is installed on a branch pipe, and a vacuum pump is installed at one end of a main pipe through an air inlet pipe. The storage box is formed by combining the multiple partition boxes, the storage box is used for independently placing extracts, the partition boxes are conveniently and independently vacuumized while mutual pollution of the extracts is effectively avoided, and the problem that the vacuum environment in the storage box is damaged when the extracts are frequently taken and placed in the storage box is solved.

Description

technical field [0001] The invention relates to the technical field of medical refrigerators, in particular to a refrigerator for forensic extracts stored by vacuum suction. Background technique [0002] When forensic scientists extract and preserve evidence, in order to ensure the safety and accuracy of the extract, it is necessary to place the extract in a low-temperature vacuum environment for strict preservation. [0003] When forensic scientists extract evidence, in order to avoid cross-contamination of extracts, the extracts need to be separated and placed separately. However, the existing refrigerators have a large overall space and are mostly integrated designs, which will increase the risk of cross-contamination of extracts. The extracts are separated and placed independently in the refrigerated cavity, which brings certain troubles to the vacuuming of the refrigerated cavity, and the frequent removal of extracts leads to the repeated destruction of the vacuum envir...

AI Technical Summary

Problems solved by technology

[0003] When the forensic doctor extracts evidence, in order to avoid cross-contamination of the extracts, the extracts need to be separated and placed independently, but the overall space of the existing refrigerators is relatively large, and Most of them are integrated design, which will increase the risk of cross-contamination of extracts, and the extracts are separated and placed independently in the inner cavity of the refrigerator, which brings certain troubles to the vacuuming of the inner chamber of the refrigerator. The vacuum environment of the cavity is repeatedly destroyed. In order to ensure the storage environment of the extract, frequent vacuuming is required, the operation is cumbersome, and the storage environment is poor. Solve the problem that the existing one-piece design refrigerator will increase the risk of cross-contamination of extracts, and the frequent removal of extracts will lead to the repeated destruction of the vacuum environment in the inner cavity of the refrigerator
