Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a tumor pathological section dehydration device. Background Art

[0002] Dehydration is a crucial step in pathological section preparation. The quality of dehydration will directly affect the preparation effect and subsequent determination of tumor nature. Poor dehydration quality will lead to inaccurate judgment of the patient's condition.

[0003] Existing tumor section dehydration generally includes two methods: physical dehydration and chemical dehydration. Among them, physical dehydration is generally carried out by means of heating, vacuum pumping, and centrifugation, etc. It is simple to operate, environmentally friendly, and causes relatively less damage to tissues. However, physical dehydration cannot completely remove all the water in the tissues, especially for tissues with high water content, and the time for physical dehydration is longer, requiring long-term observation by operators, and the control requirements for dehydration are high. Chemical dehydration, on the other hand, uses dehydrating agents to displace the water in the tissues. The dehydrating agents enter the interior of the tissues through osmosis, combine with or replace water molecules, thereby achieving the dehydration effect, and can more thoroughly remove the water in the tissues, ensure the dryness of tissue samples, and achieve the dehydration effect faster. However, chemical dehydration requires the use of a large amount of chemical reagents, with high costs and may have a certain impact on tissues.

[0004] Therefore, the present application designs a tumor pathological section dehydration device to solve the above technical problems. Summary of the Invention

When the transmission sleeve 54 is pressed down and sleeved on the connecting pipe 32, the sealing performance between the transmission sleeve 54 and the connecting pipe 32 is increased to prevent leakage of the dehydrating agent.

[0048] For a further optimized solution, the liquid inlet assembly 6 includes a first container 61 disposed in the workbench 1 for containing a dehydrating agent and a second container 62 for containing a regulator.
