  • Patent number: 11911565
    Abstract: A twist to lock heat and moisture exchanging device includes a housing having a first opening that is adapted to open to a tracheostoma and a second opening that opens to ambient. A foam filter is disposed in the housing and a closure member is mounted to the housing and adapted to close a passage between the first opening and the second opening. A locking mechanism is engageable to prevent movement of the closure member to close the passage and disengageable to allow movement of the closure member to close the passage. The twist to lock tracheostoma heat and moisture exchanger allows a user to protect from accidental closure during activities when it would be preferred like sleeping and exercising.
