我们根据过去应用的多种胃肠减压器的优缺点,于1960年自制一种气球式轻便胃肠减压器,经多年临床应用,证明共性能良好,现介绍如下。一、结构与使用方法(见附图): (一)主要配件为2个输血瓶或其它类似的玻璃瓶、1个玻璃双活塞、1个血压计气球带活门、1～2个橡皮气球(市售玩具)及木箱1只。 (二)使用时先将气门螺丝拧紧,用血压计气球打气,则甲瓶内之气球膨胀,此时双活塞玻璃管内受气流的影响使A活塞开放,B活塞关闭,甲瓶内之气体通过A活塞周围自出气口排出。待橡皮气球胀满甲瓶,即将气门螺丝拧开,则瓶内气球因弹性收缩、甲瓶内产生负压,此时A活塞关闭,B活塞
We based on the past, the advantages and disadvantages of a variety of gastrointestinal decompression, self-made in 1960, a balloon-type light gastrointestinal decompression device, after years of clinical application, to prove that the overall performance is good, are presented below. First, the structure and use (see photo): (a) The main components for the two transfusion bottles or other similar glass bottles, a glass double-piston, a sphygmomanometer balloon with a valve, 1-2 rubber balloon Commercial toys) and a wooden box. (B) the first use of the screw tighten the valve, with a sphygmomanometer balloon cheer, the bottle of the balloon expansion, this time double piston glass tube by the impact of the air to A piston open, B piston closed, the gas inside the bottle A piston around the vent from the discharge. Until the rubber balloon full of A bottle, the screw is about to unscrew the valve, the bottle due to the elastic contraction of the balloon, A bottle of negative pressure, then A piston closed, B piston
