Provox HME

For pulmonary protection and respiratory rehabilitation, as well as an improved vocal rehabilitation, a special heat and moisture exchanger (HME) has been developed, which contains also a ‘speech valve’ with a spring for easy and comfortable digital closure of the stoma, the Provox HME. This device is shown in right figure, and will be discussed in chapter VII in more detail.

An additional device, used in conjunction with the Provox HME Adhesive base plate, is the Provox Shower Aid, (figure right below) which prevents aspiration of water during showering.
