Abstract: A medical securing device (1) comprising a flexible strap (2) including a longitudinal slot (4) proximal to a transversely narrow bridge section (3) disposed between distal end portions (6, 7), wherein the end portions are connectable to a medical neckband.

Abstract: A tracheostoma cannula mounting, a cannula assembly incorporating such a mounting, and a method of mounting the same within a stoma are described. The mounting includes a generally planar sheet portion (2) provided with an aperture (4) therein of suitable size and shape to engage a channel portion of a tracheostoma cannula (21) in interference fit so as to present a rearward mounting face (18) adapted in use to lie against the skin of the tracheostoma patient in the vicinity of the stoma. The material from which the sheet (2) is fabricated comprises tacky gel material such as silicone gel at least in the vicinity of the mounting face (18), and is preferably made essentially entirely from such material.

Abstract: A tracheostoma valve is described for use within a tracheostoma to facilitate speech by use of a vocal prosthesis, which consists of a valve housing defining a valve cavity having an airflow passage therethrough between at least one rearward and at least one forward aperture, and a valve member. The valve member includes a fixed rear portion connected to a forward portion by a collapsible sleeve such that the forward portion is deployable from a collapsed configuration under vegetative breathing pressure wherein the air flow passage is open to an expanded configuration under speech pressure whereat the forward portion acts to restrict flow through the air flow passage.

Abstract: A filter assembly for filtering air that is to be breathed through a tracheostoma comprises (a) a housing, and (b) a filter component which can be fitted into the housing the filter component is movable within the housing as a result of a pressure difference across the component due to breathing, between an inhalation position, and an exhalation position resulting in a change in resistance to breathing through the assembly.
