胃肠减压器是腹部外科一项重要的治疗方法。过去使用的胃肠减压器使用方法笨重,造价较高,体积较大。而我院采用一种和我厂有关技术人员共同研制的简便有效的单向阀简易胃肠减压器(类似人工呼吸囊)应用效果良好,达到治疗目的,故介绍如下: 1.用途:①胃肠减压,②负压吸引。 2.结构原理:附图纸。单向阀长6厘米,直径0.8厘米有机玻璃为原料制造的一种三通管,左侧和密闭普通玻璃瓶(负压瓶)一管相连,负压瓶另一支管和胃管相连,单向阀下方进气孔内加一个不锈钢丝弹簧的20毫升或10毫升注射器相连。当单手反复指压注射器后,单向阀内
Gastrointestinal decompressor is an important surgical treatment of abdominal surgery. The past use of gastrointestinal decompressor using bulky, higher cost, larger. And our hospital using a technical staff and I plant jointly developed a simple and effective one-way valve simple gastrointestinal decompression device (similar to the artificial respiratory capsule) with good results, to achieve the purpose of treatment, it is described as follows: 1. Uses: ① Gastrointestinal decompression, ② negative pressure to attract. 2. Structural principle: with drawings. One-way valve length 6 cm, diameter 0.8 cm Plexiglass as a raw material to produce a three-way pipe, the left and sealed a common glass bottle (negative pressure bottle) connected to one tube, and the other tube connected to the negative pressure tube and gastric tube, single Connect a 20 ml or 10 ml syringe with a stainless steel wire spring into the air inlet below the valve. When one-handed repeated finger pressure syringe, one-way valve
