驻扎在无电气设备地区的一些医疗组织如手术队、战地医院、卫生营、卫生连,在手术中的照明就成了相当困难的问题。尤其在进行胸腹部的外科手术时,其困难更为显著,而照明良好否,是决定手术成败条件之一。因此,如何解决手术照明问题是相当重要的。在野战情况下多用汽灯(手提式和座式二种)此灯之光线亮而强,然而光线散而不聚,不易照入深部,再加以术者与助手之栏挡光效不能发挥。为解决此矛盾,我们曾在吊式汽灯周围加以益罩使汽灯之单个光源变成多数光源。经实验证明,效果良好,轻便易于携带、制作简单,价格低廉,符合多快好省的要求。 Some medical organizations stationed in areas without electrical equipment, such as surgical teams, field hospitals, health camps, health centers and the like, have become rather difficult issues for lighting in operation. Especially in the chest and abdomen surgery, the more significant the difficulties, and good lighting, is to determine the success or failure of surgery one of the conditions. Therefore, how to solve the problem of surgical lighting is very important. In the case of field use of gas lamps (portable and seat two kinds) The light of this lamp is bright and strong, but the light scattered without convergence, not easy to take into the deep, plus the surgeon and assistant of the bar block light effect can not play. In order to solve this contradiction, we have been around the hanging steam lamp to cover the light of a single light source into the majority of light source. The experiment proved that the effect is good, light and easy to carry, simple production, low prices, in line with the requirements of more fast and better.
