Medical slice production solvent

Abstract

The invention belongs to the technical field of medicine, relates to a solvent, and provides a medical slice production solvent. The medical slice production solvent is characterized in that the medical slice production solvent (abbreviation of a EFCE solvent) is prepared by adopting a certain weight percentages of an eco-friendly special solvent oil, chloroform, ethanol and other raw materials, and a large amount of pathological slice production application results show that: no toxicity and no harm are generated to staffs, no environment pollution is generated, a slice production time and slice quality reach levels of slices produced by the existing xylene solvent, and use is reliable and precise so as to provide an ideal xylene replacement solvent.

Description

technical field [0001] The invention belongs to the field of medical technology, relates to solvents, and specifically proposes a medical tablet-making solvent. Background technique [0002] In the experimental production of human or animal specimens in hospitals, after dehydration, transparency, wax immersion, wrapping, sectioning, dewaxing, dyeing, and transparency, xylene has been used as a medium solvent for a long time, and has been widely used. [0003] Xylene is an aromatic compound, a colorless transparent liquid with a refractive index of 1.495 and a boiling point of 144°C. It is volatile at room temperature, has an unpleasant smell, is highly toxic, and is insoluble in water. [0004] In use, it directly affects the laboratory working environment and outdoor environment, and is especially toxic to the staff. It enters the body mainly through respiratory inhalation and skin contact, and damages the nervous system and blood system. Long-term exposure can cause neura...

AI Technical Summary

Problems solved by technology

[0005] In the process of pathological film production, if the transparent time of xylene is not well grasped, the tissue is likely to shrink, harden and become brittle, which will affect the quality of film production

Under the condition of expensive recovery and treatment of xylene, waste xylene directly pollutes outdoor water sources and air environment

[0006] Many scholars at home and abroad have paid a lot of labor to solve this problem. They have tried to replace xylene with turpentine, clove oil, camphor oil, tert-butanol, etc., but using these as solvents, the transparency and dewaxing effect are far inferior to xylene. Problems such as high acid value and unsatisfactory antioxidant capacity have been troubled
