Hospital ultraviolet disinfection lamp is a kind of equipment that uses ultraviolet radiation to kill bacteria, viruses and other microorganisms. Ultraviolet sterilization is to destroy and change the structure of microbial DNA(deoxyribonucleic acid) through ultraviolet radiation, so that bacteria immediately die or can not reproduce offspring, to achieve the purpose of sterilization and disinfection.
The real bactericidal effect is UVC ultraviolet light, because C-band ultraviolet light is easily absorbed by the DNA of the organism, especially the ultraviolet light of about 253.7nm is the best. This band of ultraviolet light in the hospital ultraviolet disinfection lamp plays an important role in sterilization.
The importance of ultraviolet disinfection in hospital
Hospital ultraviolet disinfection lamps play a vital role in the medical environment. Regular use of ultraviolet disinfection lamps for disinfection can effectively prevent hospital infection and ensure the health and safety of medical staff and patients. To choose the right UV lamp, in order to make disinfection twice the result.
According to the disinfection technical specifications, the selection of ultraviolet rays for medical grade sterilization can be summarized as three points:
-
Require C-band ultraviolet 200-275nm(253.7nm effect is best),
-
Lamp power ≥30W, and UV intensity ≥70μW/cm at 1 meter,
-
By volume, ≥1.5W per cubic meter

Precautions for ultraviolet disinfection
In the process of use, the surface of the UV lamp should be kept clean, wiped once a week with 70%-80%(volume ratio) alcohol cotton ball, found that the surface of the lamp has dust, oil, should be wiped at any time.
Ultraviolet disinfection can only be used for indoor air disinfection under unmanned conditions, the doors and Windows should be closed during disinfection, and the room should be ventilated after irradiation for a period of time. Do not let the ultraviolet light source shine on the person, so as not to cause damage.
In order to protect the skin from damage, long long-sleeved work clothes should be worn when performing ultraviolet detection, which can protect the exposed parts and avoid causing skin damage. In order to protect your eyes from damage, you should wear sunglasses or a protective mask.
The service life of the ultraviolet lamp is 1000 hours, the department should do a good job of the lamp application time, irradiation cumulative time record and sign, more than 1000 hours should be replaced with a new tube.
The hospital awareness room shall monitor the radiation intensity of ultraviolet lamps used in the whole hospital once every six months and store the monitoring results. The department shall monitor the intensity of ultraviolet lamps with starlight cards once a month.
