Product Description

Medical Ethylene Oxide Sterilizer


Medical ethylene oxide has a bactericidal effect,does not corrode metals,and has no residual odor.Therefore,gas sterilizers that can be used as materials,Ethylene oxide sterilizer are also widely used to disinfect medical products such as bandages,sutures,and surgical instruments.
Second,the impact of sterilization factors
Factors that affect the sterilization effect include temperature,humidity,concentration,time,pressure,and packaging methods.
1,Medical ethylene oxide temperature:
The normal temperature limit is generally 37°C~63°C,the most commonly used temperature is generally 50±5°C.However,when the temperature is high enough to maximize the effect of the drug, the bactericidal effect is no longer improved when the temperature is raised.The determination of the sterilization temperature is related to the following conditions:1)Temperature tolerance of the extinguished product.2)The loading capacity and loading method require that the loading volume be≤80%,and the cabinet wall should not be touched.There should be a clearance of not less than 5cm between each cabinet.3)The thickness,size,and bulk density of packaging materials.
2,Medical ethylene oxide humidity
The moisture content of the sterilized article,the degree of drying of the microorganism itself,and the relative humidity of the environment all have an effect on the sterilizing effect of EO.When the relative humidity is lower than 30% RH,the sterilization effect is significantly affected.Therefore,wet microbes are easier to extinguish than dry ones,but the extermination effect is not proportional to the relative humidity.The humidity is too high and EO is diluted and hydrolyzed.Therefore,the humidity before dosing after vacuuming should be controlled within the range of 30%RH to 80%RH.
3,Medical ethylene oxide pressure
The degree of pre-vacuum determines the amount of residual air,and the amount of residual air affects the pressure after the EO is added and the ease with which the hot and humid heat enters the interior of the article.Therefore, the pressure,especially the pressure before humidification,has a great influence on the sterilization effect.The pressure should be set according to the sealing performance of the equipment itself and the positive and negative pressure resistance of the extinguished items.In the equipment operation and the objects can withstand,the vacuum sterilization generally has a better effect than the positive pressure sterilization.
4,Medical ethylene oxide ethylene oxide concentration
As an important factor affecting the sterilization effect,the sterilization effect can be enhanced by increasing the concentration.In a certain concentration range,when the other conditions such as temperature and humidity are the same,as the concentration increases,the time required to exterminate and kill a certain concentration of microorganisms is shorter, and the killing effect is better.
5,Medical ethylene oxide time
Under the same conditions,the longer the sterilization time,the smaller the survival probability of microorganisms and the better the sterilization effect.In addition to time other than the same conditions of the parameters,determine the shortest effective time(half-cycle)of ethylene oxide without viable bacteria,the process requirements of the action time should be twice the half-cycle.
6,Medical ethylene oxide determine the process parameters
Pre-sterilization preparation and packaging:The items to be sterilized must be thoroughly cleaned.Please be careful not to wash with normal saline.There must be no water droplets or water on the sterilization items,so as to avoid dilution and hydrolysis of ethylene oxide.Ethylene oxide can be used for the sterilization of almost all medical supplies,but it is not suitable for the sterilization of foods, liquids, oils and fats,talcum powder and animal feed.Suitable for ethylene oxide sterilization packaging materials are paper,composite dialysis paper,cloth,non-woven fabrics,vented rigid containers,polyethylene,etc.;can not be used for ethylene oxide sterilization packaging materials are metal foil,PVC,cellophane,nylon,polyester,non-permeable polypropylene.Changing the packaging material should be verified to ensure the reliability of sterilization of sterilized items.Sterilized items loading:There should be gaps in the upper and lower left and right sides of the loaded items in the sterilizer(sterilized items can not touch the wall of the cabinet).The items should be placed in the metal mesh basket or on the metal grid;the loading amount of the items should not exceed the cabinet 80% of the total volume inside.Sterilization:It should be performed in accordance with the operating instructions of the manufacturer of ethylene oxide sterilizers;according to the types of sterilization items,packaging, loading capacity and methods,
