    • A respirator that comprises a head piece (1) that is shaped to form a breathing zone (13) around at least the nose and mouth of the wearer, and an air flow passage (15, 34) for supplying a forced flow of air to the breathing zone. The air flow passage has a constricted portion (46) that includes a flow detecting orifice (52). The forced flow of air generates suction at the flow-detecting orifice. A pressure-responsive indicator device (30) is in fluid communication with the flow-detecting orifice through a tube (54) and is operable to alert the wearer if the suction generated by the air flow through the passage falls below a predetermined value.
    • 一种呼吸器,包括头部件(1),其被成形为围绕至少所述穿戴者的鼻子和嘴部形成呼吸区域(13);以及空气流动通道(15,34),用于将强制流动的空气供应到 呼吸区。 气流通道具有包括流量检测孔(52)的收缩部分(46)。 空气的强制流动在流量检测孔处产生抽吸。 压力响应指示器装置(30)通过管(54)与流量检测孔流体连通,并且如果通过通道的气流产生的吸力是否低于预定值,则可操作以警告穿戴者。
