摘要： A method for simulating speech in a tracheotomized individual includes providing a source of compressed air, regulating the air pressure, and controlling the flow of air from the source between a condition in which airflow is stopped and a condition in which airflow is allowed in response to actuation by the individual. The air flow is supplied to a reed to vibrate it, and the resulting vibration-modulated air flow is introduced into the pharynx of the individual, permitting the individual to articulate audibly comprehensible speech. Apparatus for carrying out this method is also described.

摘要： In combination with an air mattress, the pressure within which is to be controlled, a first switch for actuation at a first air pressure and a second switch for actuation at a second air pressure higher than the first. The difference between the first and second air pressures defines a zone within which the air pressure in the mattress is not controlled. The first and second switches have air inlets. A source of compressed air has an outlet. An electrically actuated air valve has an air inlet and an air outlet. The first and second switches are coupled across a source of electrical power for controlling the supply of compressed air from the compressed air source to the mattress and exhausting compressed air from the mattress, respectively.
