Abstract
In a tracheostomy tube structure, a neckplate of the tube structure and on elbow dis-connectible from the structure, the steps include providing flexible band means, attaching the band means to the neckplate, extending the band means to retain the elbow, and tightening the band means to hold the elbow against inadvertent disconnection from the tube structure.
Claims19
The method that includes the steps
- a) providing a tracheostomy tube structure, a neckplate on said tube structure and a duct disconnectible from the tube structure, the neckplate provided to have two wings,
- b providing flexible bands means, and providing two clips attached to said band means,
- c attaching said band means to said neckplate by releasably attaching said clips to said wings, respectively,
- d extending said band means to retain said duct,
- e and tightening said band means to hold said duct against inadvertent disconnection from said tracheostomy tube,
- f the clips provided to have operative connection to the duct only through the band means.
A tracheostomy tube structure comprising a tracheostomy tube, a neckplate carried on said tracheostomy tube, a duct having a tubular portion for endwise attachment to said tracheostomy tube, the combination comprising
- a) a flexible band means attachable to said neckplate,
- b) the band means having sufficient length to retain said duct,
- c) and tightening means engaging said band means, enabling manual tightening of the band means between the duct and said neckplate, thereby to hold the duct against inadvertent disconnection from said neckplate,
- d) the neckplate having two oppositely extending wings, there being two clips respectively attached to said wings, the band means having two sections respectively attached to the clips, each clip having two legs and retention means thereon releasably attached to a wing so that the two band sections exert retention force at opposite sides of the duct,
- e) the clips having opposite connection to the duct only through the band means.
A tracheostomy tube structure comprising a tracheostomy tube, a neckplate carried on said tracheostomy tube, a duct having a tubular portion for endwise attachment to said tracheostomy tube, the combination comprising
- a) a flexible band means attached to said neckplate, the neckplate having two wings, there being at least one clip attached to said band means, said one clip having legs releasably attached to one of said neckplate wings whereby the band means is releasably attached to the neckplate,
- b) the band means having sufficient length to retain said duct,
- c) the band means adjusted to be tightened between the duct and said neckplate thereby to hold the duct against inadvertent disconnection from said neckplate,
- d) said duct and tube structure having interfitting surfaces, the band means exerting force along two directions at generally opposite sides of said interfitting surfaces,
- e) said band means extending toward said neckplate at said generally opposite sides of said interfitting surfaces,
- f) and there being connection lugs on the legs of said one clip, said legs being relatively movable,
- g) the clips having operative connection to the duct only through the band means.
