The invention concerns a collar with a tracheotomy cannula or tube, wherein the collar embraces a respiratory tube in sealing relationship. The collar comprises separate inner and outer films, the outer film being elastically stretchable. The collar of the device allows no or only small tight folds formed which do not affect sealing integrity between the collar and the trachea wall even at low pressures. The outer film is expandable to a diameter larger than the diameter of a trachea, and in particular is at least 1.5 times the outside diameter of the tube, and the inner film comprises a material of lower elastic stretching. The inner film is produced oversized and without an external restriction at an internal pressure of at most 20 hPa assumes a diameter which is larger than the diameter of a trachea.

Collar of a respiratory device

A tracheotomy cannula apparatus with a shield plate is provided for fixedly gripping the cannula with a housing assembly portion of the apparatus. A pair of wing structures form a portion of the apparatus and are attached to the housing assembly, which wing structures assist in holding the cannual apparatus to a patient. The housing assembly includes a housing member through which the cannual is passed. A shield plate is affixed to one side of the housing member, which side is intended to face a patient, and whereby the cannula passing through the housing member also passes through the shield plate. A prestressed spring structure is positioned within a housing member to normally apply pressure against the cannula, thereby holding it in fixed relationship to the housing member. This spring structure has a release actuation member which when operated permits a slide movement of the cannula through the housing member. The wing structures each include an interlocking structural portion, which may be unlocked from each other. This interlocking portion holds the two wing structures in fixed positional relationship to each other when engaged.
