Atos Medical Inc Provox FreeHands HME Cassette.

The Provox Freehands HME combines an HME with an easy- to-operate automatic tracheostoma valve that lets you speak without having to manually close the stoma. It has an automatic, reusable Multi-Magnet and Multi-Valve System that helps keep the speech valve closed while you are speaking. Whenever you cough, the cough-relief valve opens and closes automatically. An HME is most effective when worn day and night. It usually takes some weeks until the pulmonary symptoms improve. During the first weeks of use, the patient may experience increased mucus production.
