氧气呼吸器(以下简称呼吸器)的结构与性能,对矿山救护活动有着直接的影响。就呼吸器的缺点而论,呼声最高的是所谓温度问题,也就是佩戴时有一种较强的闷热感,呼吸不畅,易疲劳,这对救护活动产生了一定的影响。近几年来,日本对闷热感的产生和消除进行了不少考察和试验,并在现有呼吸器的基础上,提出了一种经济可行的改进方法,现分述如下。 The structure and performance of oxygen respirator (hereinafter referred to as respirator) have a direct impact on mine ambulance activities. On the shortcomings of the respirator, the highest voice is the so-called temperature problem, which is worn when there is a strong sense of sultry, poor breathing, fatigue, which ambulance had a certain impact. In recent years, Japan has made a lot of investigation and test on the emergence and elimination of sultry feeling. Based on the existing respirator, a feasible and economically feasible improvement method is presented as follows.
