Description
Technical Field
The invention relates to the technical field of medical auxiliary instruments, in particular to a method and a device for removing sterilizing gas in dialysis product packaging
Background
Ethylene oxide is the 2 nd generation chemical disinfectant appearing after formaldehyde, is still one of the best cold disinfectants until now, and is the most important member of the four major low-temperature sterilization technologies (low-temperature plasma, low-temperature formaldehyde steam, ethylene oxide and glutaraldehyde) at present. Because the ethylene oxide has the advantages of high efficiency, broad spectrum, strong penetrating power, no damage after acting on articles and the like, the ethylene oxide becomes an important means for disinfecting and sterilizing medical and sanitary articles in China. It is often used for the disinfection of leather, plastics, medical instruments, precision instruments, and particularly for the disinfection of valuable articles such as interventional therapy materials.
But the ethylene oxide is a central nerve inhibitor, a stimulant and a raw stock poison except for the disinfection effect, acute poisoning can be caused by inhaling a large amount of ethylene oxide, and patients with the poisoning have severe throbbing headache, dizziness, nausea, vomiting, lacrimation, choking cough, chest distress and dyspnea; the severe cases have coma due to general muscular tremor, speech disturbance, ataxia, sweating and obnubilation. Myocardial damage and liver dysfunction may also be seen. After the rescue and recovery, there may be transient mental disorder, delayed functional aphonia or central hemiplegia. The skin rapidly becomes red and swollen when being contacted, bubbles after a plurality of hours, and can be sensitized after being contacted repeatedly. Liquid splashes into the eye and can cause corneal burns. Chronic effects: a small amount of contact for a long time can show neurasthenia syndrome and vegetative nerve functional disturbance.
In the current blood purification treatment, dialyzers and blood tubes are often used, and the two types of medical devices are basically sterilized and packaged by using ethylene oxide gas, namely, the packaging bags of the dialyzers and the blood tubes are filled with ethylene oxide. The dialyzer and the blood line are used as disposable devices, and replacement of patients requires medical staff to continuously replace the new dialyzer and the blood line. Hospitals are used as places with dense crowds, particularly dialysis rooms are used as relatively closed spaces, and the ethylene oxide released by continuously unsealing dialysis product packages easily causes physical damage to medical staff and peripheral staff after long-term accumulation, and even possibly causes poisoning phenomena. Meanwhile, in order to achieve the disinfection effect, the cavity of the dialysis article body is in a non-sealed state, and residual ethylene oxide in the cavity easily enters a human body in the dialysis treatment process, so that discomfort or allergy and other diseases of a dialysis patient are caused, and the whole treatment is obviously affected.
