Abstract (en)

[origin: EP1614447A1] A respirator speech transmitter and exhalation valve module includes an electrical communication block with internal and external fittings for connecting a microphone in the mask to a radio or amplifier carried by the mask user. The module comprises a resilient exhalation valve having a low airflow resistance for exhalation but providing a secure seal against inadvertent inhalation through the exhalation valve module. An exhalation airflow channel is formed between a module body on the outside of the channel and a conical airflow guide and the exhalation valve on the inside of the channel. The exhalation airflow channel is in the form of an amplification horn. The airflow channel produces a smooth airflow for unrestricted exhalation and high intelligibility of a user's speech. The module includes a drinking conduit for selectively fluidly connecting a mouthpiece in the respirator to a beverage container.
