The application of external disinfection lamp in hospital surgery is crucial link, it is not only directly related to the health status of the operating room, but also affects the success rate of surgery and postoperative recovery of patients. The following is a detailed description of the application requirements of ultraviolet disinfection lamps in hospital surgery.
I. Choose the appropriate UV disinfection lamp
First of all, when hospitals choose ultraviolet disinfection lamps, they need to ensure that they meet medical-grade standards and have efficient sterilization capabilities and stable performance. Ultraviolet disinfection lamps can destroy the DNA structure of microorganisms by emitting ultraviolet rays of specific wavelengths (mainly UVC band), thereby achieving the purpose of sterilization and disinfection. Therefore, the selected ultraviolet lamp should have high radiation intensity and appropriate wavelength range to ensure its disinfection effect.

II. Installation and layout requirements
1. Installation height: The installation height of the ultraviolet disinfection lamp should be moderate, and it is usually recommended to be between 1.5-2 meters from the ground. This height ensures that the UV rays can evenly cover the entire operating room area and improve the disinfection effect.
2.Reasonable layout: The layout of the operating room should take into account the effective irradiation range of the ultraviolet disinfection lamp and avoid dead corners and blind areas. At the same time, the installation position of the ultraviolet lamp should avoid direct exposure to the eyes and skin of the operating personnel or patients to prevent potential damage.
3.Fixed or mobile options:Depending on the specific needs of the operating room, fixed or mobile UV disinfection lamps can be selected. Fixed UV lamps are suitable for routine disinfection, while mobile UV lamps are more convenient for focused disinfection of specific areas in the operating room.

III. Operating instructions
1. Irradiation time: The irradiation time of the ultraviolet disinfection lamp should be set reasonably according to the actual situation. Generally speaking, 30-60 minutes of disinfection are required before surgery, and disinfection can be continued during the surgery, and will be extended for another 30 minutes after the surgery is completed and cleaned. For special situations where there are a lot of people or before invasive operations, the number of disinfections can be appropriately increased or the disinfection time can be extended.
2 .Close doors and windows: During the ultraviolet disinfection process, the doors and windows of the operating room should be kept tightly closed to prevent external air flow from affecting the disinfection effect. At the same time, it is strictly forbidden to block the air inlet and outlet with objects to ensure the effective spread of ultraviolet rays.
3. Personal protection: Ultraviolet rays cause certain damage to the human body, so no one is allowed to stay in the operating room during the disinfection process. Medical staff and patients should leave the operating room before disinfection begins and take appropriate protective measures, such as wearing goggles and protective clothing.
4. Recording and Monitoring: After each disinfection, information such as "disinfection time" and "accumulated hours of use" should be recorded on the "Ultraviolet Lamp/Air Disinfection Machine Use Registration Form". At the same time, the intensity of the UV lamp should be monitored regularly to ensure that it is in effective working condition. When the service life of the UV lamp is close to or the intensity is lower than the specified standard, it should be replaced in time.
IV. Maintenance
1. Regular cleaning: UV lamps will gradually accumulate dust and dirt during use, affecting their radiation intensity and disinfection effect. Therefore, UV lamps should be cleaned regularly. It is generally recommended to wipe them with 95% alcohol once a week and perform deep cleaning once a month.
2. Filter cleaning :For ultraviolet circulating air air sterilizers equipped with filters, the filters should be cleaned regularly to prevent clogging. The water temperature during cleaning should not exceed 40°C, and brushing is prohibited to avoid damaging the filter. Under normal circumstances, the continuous use cycle of the filter is one year, but it should be adjusted appropriately according to the actual situation and frequency of use.
3. Equipment inspection: In addition to cleaning and replacing lamps, UV disinfection equipment should also be comprehensively inspected and maintained regularly. Including checking whether the power cord, control switch and other components are intact, and whether the overall operating status of the equipment is normal.
V. ENVIRONMENTAL REQUIREMENTS
1.Cleaning and drying: During the UV disinfection process, the operating room should be kept clean and dry. Avoid accumulation of water or dirt on the floor and walls to avoid affecting the penetration and disinfection effect of ultraviolet rays.
2.Suitable temperature and humidity: The temperature and humidity of the operating room should be controlled within a certain range. Generally speaking, the suitable temperature range is 20 to 40 degrees, and the relative humidity should be ≤60%. When this range is exceeded, the disinfection time should be appropriately extended to ensure the disinfection effect.
VI. Personnel management and training
1. Strict management: The number and flow of personnel in the operating room should be strictly controlled. During the operation, the number and time of personnel entering and exiting the operating room should be minimized to reduce the risk of external contamination.
3.Professional Training:Medical staff should receive professional training on ultraviolet disinfection knowledge and understand the principles, operating specifications, precautions and personal protection measures of ultraviolet disinfection. Ensure correct operation and effectively avoid potential risks during use.
In summary, the application of ultraviolet disinfection lamps in hospital operations requires strict compliance with a series of requirements and specifications. By choosing the appropriate UV disinfection lamp, reasonable installation and layout, standardized use and operation, regular maintenance and maintenance, and maintaining good environmental conditions and personnel management, we can ensure that the UV disinfection lamp exerts the maximum disinfection effect in the operating room and protects patients. safety.
