Abstract:
A tracheostomy tube comprising:an outer cannula having one end including at least one tab means extending therefrom;an inner cannula removably matable to said outer cannula having a first end;collar means rotatably coupled to said first end of said inner cannula, said first end of said inner cannula not extending beyond said collar means, said collar means having at least one opening to which said tab means can mate with said collar means when said inner cannula is mated to said outer cannula; andpressure means fitted within said collar means;wherein, after said inner cannula is mated to said outer cannula and said tab means mated to said collar means, and said collar means is rotated to move said opening away from said tab means, said outer and inner cannulas are ensured to remain fixedly mated to each other due to said pressure means effecting a biasing force against said tab means to thereby prevent inadvertent rotation of said collar means relative to said tab means.
