Background

Hospital surgical resection specimens mostly use 4% formaldehyde solution as a fixative. Formaldehyde is a volatile toxic substance with a strong pungent smell, and acute toxic reactions are manifested by irritation and damage to skin mucosa and respiratory system. Subacute and chronic toxic reactions, in addition to respiratory toxicity, also cause chronic injury and clinical symptoms in organs such as the central nervous system, immune system and liver. Prolonged exposure can also induce gene mutations, neonatal teratogenesis and malignancy. Pathologists and technicians are exposed to formaldehyde for a long time in the operation processes of observing, describing, recording, drawing materials, re-fixing and the like of fixed specimens. The large pathological sampling platform capable of completely and quickly replacing polluted air is high in price and high in installation requirement.
