近几年来,我们在需要而得不到成品的情况下,利用废器材零件及其他物品,试制了一些简单器材,颇为经济实用。特介绍如后,以便共同研究和改进。一集光灯用途检查眼结膜、房水、前房、虹膜、瞳孔、晶体等,可以初步代替槌状照明灯和斜照法的应用。制法用普通质量较好的手电筒一个,20D(或13D)双凸镜一个。把20D 的双凸镜裝在电筒平玻璃后面。使用时,因平玻璃后面有20D 双凸镜即起集光作用,把焦点对准要检查的部位,右手持电筒,左手持扩大镜,移动焦点,寻找病变。
In recent years, we have tried out some simple equipment using scrap parts and other items without the need of finished products, which is quite economical and practical. Special introduction, such as in order to jointly study and improve. A set of light use eye examination conjunctiva, aqueous humor, anterior chamber, iris, pupil, crystal, etc., can be the initial replacement of mallet lighting and oblique illumination method. Method with a better general quality flashlight one, 20D (or 13D) a double-convex lens. The 20D double convex lens mounted on the back of the flashlight flat glass. When used, due to the flat glass behind the 20D double convex lens that plays a role in collecting light, the focus at the site to be checked, right hand torch, left hand holding magnifying glass, move the focus, looking for lesions.
