A kind of high temperature and ultraviolet Multifunctional sterilizing cabinet
Technical field
This utility model relates to a kind of disinfection cabinet, is specifically related to a kind of high temperature and ultraviolet Multifunctional sterilizing cabinet, belongs to technical field of medical equipment.
Background technology
Disinfection cabinet refers to by modes such as ultraviolet, far infrared, high temperature, ozone, the instrument of sterilizing, insulation dehumidifying is carried out to article such as tableware, tableware, towel, medicated clothing, cosmetology apparatus, medical apparatus and instruments, profile is generally cabinet box like, and cabinet body major part material is rustless steel.
At present, hospital all can carry out disinfection to reusable medical apparatus and instruments, but be mostly put into sterilization pool or disinfection trough immersion and sterilize, the medical apparatus and instruments after poison that disappeared needs medical personnel to bring glove to be pulled out, this can not carry out disinfection to medical apparatus and instruments to a certain extent completely, disinfectant solution is easy to the both hands polluting medical personnel, and medical apparatus and instruments is after sterilization all moister, this is unfavorable for that medical personnel use, the shortcoming existed is that drug immersion is larger to medical apparatus and instruments infringement, drying time is long, wiping is incomplete, sterilize not thorough, abnormal smells from the patient is denseer.
So the art also adopts ultraviolet disinfection cabinet to carry out disinfection sterilizing to medical apparatus and instruments.Ultraviolet radiation for sterilizing and disinfecting utilizes the ultraviolet of suitable wavelength can the molecular structure of DNA (DNA (deoxyribonucleic acid)) in destroy microorganisms body cell or RNA (ribonucleic acid), cause that growth sexual cell is dead and (or) regenerative cell is dead, reach the effect of sterilizing.Ultraviolet Disinfection is on the basis based on modern times anti-epidemiology, medical science and photodynamics, utilize the high efficiency of particular design, high strength and long-life UVC wave band irradiation under ultraviolet ray, various antibacterial, virus, parasite, algae and other pathogen are directly killed.
Ultraviolet has certain bactericidal action, but excessive radiation ultraviolet is harmful.When skin, can there is solar dermatitis in ultraviolet strong effect, skin occurs erythema, itch, vesicle, edema, ophthalmalgia, to shed tears, serious also can cause skin carcinoma.In central nervous system, headache, dizziness, body temperature rising etc. can be there are in action of ultraviolet radiation.Act on eye, conjunctivitis, keratitis can be caused, be called photophthalmia, also likely bring out cataract.
Therefore, the adjustable protection Design of ultraviolet should be carried out as the disinfection cabinet with people's Long Term Contact, effectively should work in away from human body, human body near time quit work.
A kind of intelligent-induction medical treatment sterilamp that domestic applications number are CN201420663523.X have employed the form that infrared induction instrument, single-chip microcomputer and alarming horn combine, improvement has to a certain extent been carried out to the use of Burdick lamp, but, this type of sterilamp does not solve Burdick lamp well to the harm of human body, meanwhile, this ultraviolet disinfection lamp, surperficial range of exposures is little, can not comprehensively sterilize, overall disinfection is thorough not.Thus, the ultraviolet ultraviolet disinfection cabinet of a kind of Intelligent adjustment is needed badly.
