Description
Technical field
This utility model relates to a kind of ethylene oxide sterilizer, refers to a kind of environmental protection micro medical ethylene oxide sterilizer especially.
Background technology
Oxirane is called for short EO, and molecular formula is: C
2H
4O, outward appearance: be colourless gas during room temperature, be lower than 4 ℃ and be colourless transparent liquid.Its boiling point: 10.8 ℃.Slightly the ether abnormal smells from the patient is poisonous.Form explosive compound, UEL (V/V): 100% with air; LEL (V/V): 3.0%.The sterilization mechanism of oxirane is an alkanisation, to the metabolism cell generation irreversible lesion of antibacterial.Amino (NH in oxirane and the bacterium protein
2), hydroxyl (OH), carboxyl (COOH) or sulfydryl (SH) combine into ethoxy, alkylating by protein molecule, cause protein to lose response gene, the metabolism of impede protein matter, suppress bioenzyme activity, make the metabolic function of bacterial enzyme be subjected to obstacle and cause thalline death.Comprising bacterial propagule, the brood cell. various microorganisms such as virus, tubercule bacillus and fungal spore all can be killed.Because oxirane is to realize sterilization under negative pressure, cryogenic conditions and in stifling mode,, do not destroy sterilization process so can not producing object.From the later stage eighties 20th century, each developed country of the world is in field extensive use, especially sterile bodies such as chemical industry, medical treatment, food, archaeology easy deformation and rotten under high temperature, high pressure effect, and is the most suitable with ethylene oxide sterilizing.For example: unearthed relics, contact lens, human body mucosa contact industries such as apparatus and chemical industry with blood.But oxirane dizziness, nauseating, dyspnea, dead until stupor can be occurred by people and animal suction pulmonary, and the not treated discharging of waste gas will be polluted vegetation, soil, water resource, the atmosphere of human survival.So international regulation: putting into atmospheric ethylene oxide gas must not be greater than 1PPm.National Specification, the aerial concentration of oxirane must not surpass 1mg/m
3
