目前国内外对医疗器械的研制在向着小型化、微型化方面发展。这不仅具有重要的医疗意义,而且有利于战备。目前供体腔照射用的紫外线灯,多为水冷式高压汞灯。这类灯灯管在点燃时产生高温,灯头必须装有水冷装置才能使用。这样使机器结构复杂,体积增大,给临床应用带来许多不便,而且机器价格昂贵,限制了紫外线治疗的广泛应用。我们于1975年开始利用盘形管紫外线灯改制成一种供体腔粘膜、局部治疗用的简易紫外线灯。简称S_z-2型紫外线灯,它具有体积小,重量轻,结构
At present, the development of medical devices at home and abroad is moving toward miniaturization and miniaturization. This not only has important medical implications, but also helps combat readiness. Currently used for irradiation of the cavity light UV lamps, mostly water-cooled high pressure mercury lamp. This type of lamp produces high temperature when ignited, the lamp must be equipped with water-cooled device to use. This makes the structure of the machine complex, the volume increases, to the clinical application of a lot of inconvenience, but the machine is expensive, limiting the widespread use of UV treatment. We started in 1975 using a disc-shaped tube UV lamp transformed into a kind of for the body cavity mucosa, a simple UV lamp for local treatment. Referred to S_z-2-type UV lamp, which has a small size, light weight, structure
