The characteristics of the hospital infection hospitals have three elements of the spread of the disease
Source: hospital is patient and pathogen carriers Windows have intimate contact opportunity;
Special transmission way: hospital in various media, pollution of medical devices and diagnosis and treatment appliance, acupuncture, blood transfusion, health care providers, hand;
Easy feeling crowd: the patient of pathogenic factor resistance ability; The overuse of antibiotics and disinfectant: cause local flora change, the resident bacteria was or killed, and the resistant strains infection; Permanent bacteria into other parts, become pathogenic bacteria.
Disinfection of hospital infection control in the role
Disinfection task: the use of physical and chemical methodsChina rapid thermometer, kill media on the various disease-causing microorganisms, cut off the transmission way.
In the hospital infection control, disinfection and sterilization have blocked the way of infection role.
In the prevention endogenous infection in laminar ventilated, China automatic digital blood pressure monitorused for patients, use immunosuppressive cachexia patients.
In the control exogenous infection, medical equipment in the disinfection, hospital environment disinfection, etc.
From the point of view of infectious diseases:
The hospital is occurring disease, it has ever existed source for the existence or the characteristics of places, therefore, should be done at any time disinfection, and the final disinfection.
The hospital and have no clear source characteristics of the existing site, therefore, should do well in hospital preventive disinfection, do the cleaning and disinfection and isolation hospital, can reduce hospital cross-infection.
The risk of hospital disinfection item level
A, highly dangerous articles:
Microbial pollution is will cause serious harm the diagnosis and treatment of equipment and supplies, this kind of goods is through skin or mucous membrane into the sterile tissue or organs internal equipment, or with the damaged tissue, close contact with skin mucous membrane of equipment and supplies, for example: surgical instruments and supplies, needles, blood transfusion equipment, the injected drug and liquid, and.n dialysis. Blood and blood products, catheters,China fever thermometer manufacturer cystoscopy, laparoscopic, viscera graft and living tissue clamp etc.
Second, moderate risk articles:
Is affected by microbial contamination may cause moderate damage after the diagnosis and treatment products, this kind of goods and only skin mucous membrane in contact, and not enter the sterile within the organization. For example: thermometer, breathing machine, gastrointestinal endoscopy, tracheal mirror, anesthesia machine, a spatula, laryngoscope, implement, tableware, tea, etc.
Three, low risk articles:
Although have microbial pollution, but usually harmless, only when a lot of pollution by pathogenic bacteria cause harm to the items. This kind of goods and equipment only directly or indirectly and health condition skin mucous membrane in contact. For example: hand towel, toothbrush, basin, spittoon (cup), ground, metope, desktop, the surface of bed, bedding, indoor air, general diagnosis equipment (stethoscope, the receiver, blood, etc), etc.
