We are familiar with the lighting equipment in the operating room, and it is very important for the hospital to purchase qualified shadowless lamps for patients, even life-threatening. Surgical shadowless lamp is an important lighting tool in surgery. For qualified surgical shadowless lamp, some main performance indexes must meet the specified standards.
Here are two standards for shadowless lamps,
First of all, the most important point is to have sufficient illumination. The illuminance of surgical shadowless lamp has reached more than 150000lux, which is close to the brightness of sunny days in summer. However, the actual illumination of 40000-100000 lux is the most appropriate. If it is too bright, it will affect the vision. Surgical shadowless lamp should not only provide sufficient illumination, but also avoid glare on surgical instruments. Glare can also affect visual acuity and vision. It is easy to make the doctor's eyes tired. It is unfavorable for surgeons to operate. The illuminance of shadowless lamp should not be too different from the normal illuminance in the operating room. According to some illuminance standards, the illuminance of overall lighting should be one tenth of that of local lighting. The overall illumination of the operating room should be above 1000lux.
Secondly, the shadowless degree of surgical shadowless lamp is higher, and the shadowless degree is an important characteristic and performance index of surgical shadowless lamp.
Any shadow formed in the surgical field of vision will hinder the doctor's observation, discrimination and operation. Good surgical shadowless lamp should not only provide sufficient illumination, but also have high shadowless degree to ensure that the surface of surgical field of vision and deep tissue have certain luminosity.
In recent years, with the improvement of living standards, people pay more attention to their own health. Operating room equipment such as surgical shadowless lamp is certainly under attention. In order to meet the needs of hospitals and pursue better products, medical device manufacturers have made better improvement and Research on operating room equipment. In order to improve light quality, they have developed and produced hard glass as reflector The multi-layer dielectric film reflective lens that can pass through infrared ray is a cold light mirror with illumination of more than 100000 lux. The mirror surface of the cold light mirror is coated with multilayer high-purity zinc sulfide, magnesium fluoride coating or titanium dioxide and silicon dioxide coating in vacuum, and the coating is uniform and free of impurities.
In order to meet the needs of doctors, a photometric adjustment device is also set on the high illumination surgical shadowless lamp. The illumination angle of the light can be changed according to the doctor's position and operation range. In this era of rapid change, medical device research companies are in order to improve the product quality Competitiveness, are constantly improving their products.
