Medical devices are highly hazardous substances must be selected sterilization method.
A medical device
Medical devices are directly or indirectly used in the human body instruments, equipment, apparatus, in vitro diagnostic reagents and calibrators, materials, and other similar or related items, including the need for computer software.
Medical devices include medical equipment and medical consumables.
Utility is obtained primarily by physical and other means, not by pharmacological, immunological or metabolic means, or is involved but only in an ancillary manner.
II. Purpose of Medical Devices
The purpose is the diagnosis, prevention, guardianship, treatment, or mitigation of disease; the diagnosis, guardianship, treatment, mitigation, or functional compensation of injuries; the testing, substitution, modulation, or support of physiological structures or processes; the support or maintenance of life; the control of pregnancy; and the use of medical devices for medical or diagnostic purposes by means of the examination of samples from the human body. samples to provide information for medical or diagnostic purposes.
Three, sterilization method introduction
Sterilization method refers to the object on all the microorganisms (including bacterial spores, including) all the methods of killing. Sterilization method is divided into physical sterilization method and chemical sterilization method, should be based on the type of microorganisms, contamination, the nature of the contaminated items and the state of the different sterilization method can be used alone or in combination.
Four, chemical sterilization method
1, gas sterilization
Gas sterilization is the use of ethylene oxide or formaldehyde microbial kill a method, mainly used for glass, magnetic products, metal products, rubber products, plastic products, fiber products, etc., but also Can be used for facilities, equipment or powdered pharmaceuticals. When using gas sterilization, the items to be sterilized are not deteriorated as a prerequisite.
2, liquid sterilization method
Usually used liquid ethanol, cresol, phenol water or formalin water, etc., for glass products, magnetic products, metal products, rubber products, plastic products, fiber products and other items, but also can be used for the finger, aseptic box or sterile equipment.
Fifth, the clinical significance of sterilization method
1, the application of surgery
Surgical instruments, dressings, the operator's arm and surgical environment sterilization, is the success of the operation, the key to wound healing, strict aseptic operation is to prevent infection, to ensure that the patient after the operation is expected to The strict aseptic operation is an important condition to prevent infection and ensure the expected recovery of health of patients after surgery.
2, the prevention of disease
Sterilization method can prevent pathogenic microbial infection, cut off the path of disease transmission, control or eliminate infectious diseases.
