The present invention relates to an improved applicator designed for the application of anesthetic fluids such as phenol as well as other fluid medicants to the tympanic membrane. The applicator comprises an articulating member with a finger gripping zone adjacent the proximal end thereof, and an angularly disposed fluid retaining applicator pad secured to the distal end thereof. The distal end is provided with a cylindrical fluid retaining applicator pad attached to the cross-sectional surface of the tip, with the outer diameter of the pad being generally equivalent to that of the articulating member. The fluid retaining applicator pad permits painless application of an anesthetizing fluids such as phenol to the tympanic membrane, with excellent positioning control being made possible by the finger gripping portion of the articulating member.

An endotracheal tube (10) including, in addition to a primary ventilating channel (11), a secondary speaking channel (12). The speaking channel (12) contains an array of exit ports (16) for the introduction of a tone into the posterior oral pharynx (23) of the intubated patient. This tone is then conducted into the oral cavity (18) wherein it is articulated into speech by the patient. This substitute vocal sound is produced by a tone generating device (19) connected to and in air communication with the speaking channel (12) of the present invention.

The present invention consists of a novel device for the production of a tone suitable for use in artificial speech aids. Artificial speech aids provide for a method of speech, for individuals who have either temporarily or permanently lost the use of their vocal cords, through the production and delivery of a substitute vocal tone to the user's oral cavity, thereby allowing such individuals to speak through articulation of the tone into words. The present invention concerns a novel device for the production of the substitute vocal tone. In the present device, the tone is produced by actuating a solenoid reed valve to a sufficient frequency that sound is produced, which sound is then amplified by the passage of pressurized air through the valve as it is actuated. The invention herein includes an electrical pulse generator for producing the pulsed electrical signal needed to operate the solenoid reed valve.
