Abstract: A tracheostoma voice prosthesis member (1) intended for insertion into a fistula between oesophagus and trachea. The member comprises a tubular body portion (2) with a proximal end opening into the trachea and a distal end opening into the oesophagus. A one-way flap valve covers a through opening of the tubular body portion (2) for allowing air to pass through the tubular body portion (2) from the proximal end to the distal end but preventing air and other matter from passing in the reverse direction. A support ring (8) supports the one-way valve and/or stiffens the tubular body portion (2) adjacent the one-way valve. The ratio between the smallest inner diameter of the through opening and the largest outer diameter of the tubular body portion (2) is larger than 58%. A safety strap (6) extends from the proximal end and is attached to the skin outside the tracheostoma by a plaster.

Abstract: A tracheostoma valve adapted to control the flow of air through a tracheostoma comprising a tubular housing having an open first end to be connected to the tracheostoma, and forming at least one side opening in the wall thereof, a shut-off valve member, and a normally closed cough valve member is disclosed. The shut-off valve member comprises a flexible diaphragm mounted in the housing and shaped to normally assume a curled position spaced from the inside surface of the housing wall to allow air flow through the housing and the side opening from trachea to the ambient atmosphere, and to engage said the surface, closing the side opening, at a predetermined air flow rate. The cough valve member controls an open second of the housing to open in response to a particular pressure achieved in the housing and to close automatically at reduction of the air pressure.

Abstract: A voice prosthesis to be mounted in a fistula between trachea and esophagus comprises a spool-shaped element with a through passage and a valve mechanism controlling the connection through said passage and having sealing surfaces which can be pressed against each other, means being provided to produce a magnet force acting between the sealing surfaces to keep said surfaces pressed against each other in the closed position of the valve mechanism.

Abstract: A vocal valve to be applied to a tracheostomized person's neck comprises an air passage to be connected with the tracheostoma for connecting the trachea with the surroundings. A check valve member is provided in the air passage, wherein the check valve member is normally closed but allows for inhalation through the air passage. The vocal valve further comprises a manually adjustable member for establishing a free air flow through the air passage at inhalation as well as exhalation.

Abstract: A vocal valve for connection to a tracheostoma comprises a filter (16) for moisture and heat exchange at breathing through the vocal valve, and a housing (15) receiving the filter and having a first opening at one side of the filter to be connected to the tracheostoma, and at least one second opening at the opposite side of the filter, which communicates with the surroundings. A manually operated valve element (15′) for blocking the air passage through the filter is constructed to close said first opening at manual operation thereof.

Abstract: Device to be connected to a tracheostoma, comprising a filter housing (10) for receiving a moisture and heat exchanging filter (11) said filter housing having a first opening (12) to be connected to the patient's stoma and at least one second opening (14) at the opposite side of the filter (11).According to the invention there is provided at said second opening (14) of the filter housing (10) a valve member for closing said second opening, said valve member being spring biased to an open position and being adapted to be manually closed by means of a finger against the spring bias.

Abstract: A method for inserting a drain catheter into an antrum includes the steps of securing a needle holder to the trailing end of a needle, positioning a hammer in predetermined spaced relation to the trailing end of the needle holder, loading a bias member so that it urges the hammer to strike the needle holder, restraining the hammer to maintain the load on the hammer, and quickly releasing the hammer and allowing it to strike the needle holder so that the leading end of the needle punctures the bone of the antrum wall. A first dampening member decelerates the hammer at the end of its displacement, and a second dampening member decelerates the needle and needle holder at the end of their joint displacement. A rigid tube is disposed in ensleeving relation to the needle so that the leading end of the tube is positioned in predetermined proximity to the point of the needle so that the leading end of the tube is carried into the antrum when the needle point punctures the antrum wall.

Abstract: A voice prosthesis is adapted to be inserted into a fistula between an esophagus and a trachea of a user. This prosthesis includes a cylindrical middle piece defining a passageway therethrough which has a groove therein and which has first and second end portions. First and second external flanges extend from respective first and second end portions of the middle piece. The middle piece and the flanges are all made of flexible material. A ring made of a material which is stiff in relation to the flexible material of the middle piece and the flanges is inserted into the groove in the passageway of the middle piece for stiffening of the middle piece. A valve is provided which includes a seat formed in the passageway of the middle piece and a flap extending across the passageway and carried by the middle piece for resting on the seat to close the passageway and is adapted to be moved off the seat to open the passageway.
