Abstract

A ventilator alarm device is described with some unique features. It has a very low current consumption. This allows prolonged operation from small batteries which may be recharged from the ambient light in the room. The device is automatically activated and de-activated by the pressure wave from the ventilator. No external switches or other controls are necessary. The very small size means that the device can be directly attached to a ventilator 'in line' with the ventilator circuit. There are no tubing connexions between the ventilator and the alarm device and no separate shelf-space is required.

摘要

描述了一种具有一些独特特性的呼吸机报警装置。它的电流消耗非常低。这使得它可以使用小型电池进行长时间运行，这些电池可以通过室内的环境光充电。该装置由呼吸机产生的压力波自动激活和停用。无需外部开关或其他控制装置。其非常小的尺寸意味着该装置可以直接“在线”连接到呼吸机上，与呼吸机回路相连。呼吸机和报警装置之间没有管道连接，也不需要单独的存放空间。
