氣管造口說話閥 / Speaking Valve

說話閥 (Speaking valve) : 
為可重複使用的裝置，含有單向震動閥與15mm轉接頭，可用於開窗式或無氣囊的氣切套管。在自發的吸氣期間，震動閥打開，且空氣經由震動閥及氣切套管被吸入氣管及肺。呼氣時震動閥關閉，強迫空氣經由打開的空氣通道並通過聲帶來發聲。當沒有連接氧氣時，蓋在氧氣接口上的蓋子是用來做為衛生的蓋子並阻擋空氣回流。震動閥的蓋子與主體可以打開，以利清潔與查視。

可接氧氣駁咀 Speaking Valve Oxygen Adaptor  (PMA2000) Passy-Muir Valve 02 Adaptor

Clip on oxygen adaptor.The Passy-Muir Valve O2 Adapter is small, lightweight, clear in colour and snaps onto both the TR PMV 1002 (Clear) and TR PMV 1003 (Purple) Tracheostomy and is easily removed when not in use. Oxygen is delivered in front of the diaphragm of the PMV to avoid complications associated with devices that provide continuous flow behind the diaphragm of a speaking valve which may include air trapping, drying of secretions and possible cilia damage.                                              

氣切發聲閥的使用，則是為協助吸氣時仍由氣切進入，

而吐氣時則由正常的吐氣路徑吐掉，不再經過氣切，

但要注意的是，千萬一定要記得把氣切氣囊中的氣給洩掉，

不然氣體只進不出，是非常危險的，
