摘要： A speaking valve assembly (2, 200) for fitting to the machine end (13) of a tracheostomy tube (1) has a one-way valve (23, 236) that allows inhalation but prevents exhalation. The assembly further includes a pressure relief arrangement that remains closed during normal respiration and vocalisation but opens when pressure in the assembly rises above a normal level. In one arrangement the pressure relief arrangement takes the form of a ball valve (30) with a ball (32) that is lifted away from an opening (31) by excess pressure but falls back to block the opening when pressure reduces. An alternative pressure arrangement has a slidable collar (226) that normally covers vent apertures (223) in a housing (220) of the assembly. When pressure in the assembly rises above a normal level the collar (226) is pushed out to expose the vent apertures (223) and allow air to escape.

摘要： An inner cannula (20) for a tracheostomy tube assembly includes a thin, inner sheath (22) supported externally by a structural frame (23) having a longitudinal portion (25) and a plurality of ribs (26) extending circumferentially and spaced along the cannula. The inner cannula (20) is inserted within and is removable from an outer tracheostomy tube (1). The inner cannula (20) is made by coating a plastic layer on a core to form the sheath and then placing the sheath on a curved core. The structural frame (23) is then moulded about the sheath (22) in a mould 80.

摘要： A coupling (2) for a tracheostomy tube (1) has first component (21) with a short sleeve (23) at its patient end that it fitted on the patient end of the machine end coupling (17) on the tube so that the machine end of the coupling extends within a part-spherical formation (24) at the opposite end of the first component. The coupling (2) includes a second component (22) with a male tapered fitting (27) at its machine end and a part-spherical formation (28) at its patient end that is a close sliding fit inside the part-spherical formation (24) on the first component (21).

摘要： A tracheal tube has a high-volume/low-pressure sealing cuff (10, 201, 310, 510, 610, 710, 810) with an outer surface provided with surface formations (211, 311, 511, 611, 711, 811) adapted to reduce the flow of secretions past the cuff. The formations could be in the form of an array of dimples (211) or a pattern of linear ridges or channels (611 or 711). Alternatively, the surface formations, could be a pattern of intersecting linear projections (311, 312, 313) or grooves (511). Instead the surface formations could be provided by a rough texture (811) on the outer wall surface.
