ABSTRACT:
A low pressure prosthesis device includes a cylindrical housing having a proximal end with strap elements extending outwardly from the proximal end, a distal end and a port operatively cooperating with a tracheostoma in the neck of a patient. The cylindrical housing further includes a one-way valve structure comprised of an annular sealing rim positioned perpendicularly in the housing adjacent the distal end and a valve membrane hingedly mounted within the housing to cooperate with the annular sealing rim to provide the one-way valve structure. An annular collar flange extends outwardly from the housing and is positioned to abut against the esophagus tissue when the device has been positioned within a fistula connecting the esophagus to the tracheostoma. The valve membrane is movable from the closed to the opened position when air passes through the port from the tracheostoma to the esophagus to produce alaryngeal speech and sounds in the patient.
