Abstract
A tracheostomy system includes an outer multi-layered tube, which can be expanded or allowed to contract as necessary in order to receive various sizes of cannula tubes. A dilator is used to initially insert the outer tracheostomy tube into the tracheostoma. After the initial installation dilator is removed, various sizes of dilators having a cannula mounted about them can be inserted into the outer tracheostomy tube. The multilayered tube will then expand in response to insertion of the various sizes of dilator cannula assembly being placed. When the dilator is removed the cannula tube will remain in place to maintain the desired diameter tracheostomy tube. This provides a means in which the diameter of the tube can be changed without having to actually remove and reinsert a different tube.
Claims16
A tracheostomy system, comprising:
- a needle and wire guide assembly insertable percutaneously through an incision into the lumen of the trachea;
- a dilator including have a flexible tubular body terminating at its distal end in a tapered portion attached to said wire guide assembly;
- a radially variable diameter tracheostomy tube having a tubular passageway to receive said dilator for radial expansion of said outer tracheostomy tube;
- a cannula having a tubular cross-section, and distal and proximal ends, to provide an airway, said cannula being substantially rigid and curved for insertion into said radially variable diameter tracheostomy tube and being insertable at its distal end into the lumen of the trachea and having a proximal end exposed at the proximal end of the tracheostomy tube for attachment to a ventilator or other medical devices.
A tracheostomy device installed in a patient, comprising:
- a radially variable diameter tracheostomy tube extending through a tracheostoma between an incision in the neck and the trachea lumen, said tracheostomy tube forming a tubular passage way;
- and
- a cannula positioned within said tracheostomy tube and terminating at its distal end within the trachea lumen, and having a proximal end adapted to connect to a ventilator or other medical equipment.
A method of inserting a tracheostomy system capable of providing ventilator passageways of varying diameters, comprising,
- installing percutaneously through the neck and into the lumen of the trachea a needle and wire guide assembly;
- inserting a first dilator attached to said needle and wire guide assembly having a variable diameter tracheostomy tube mounted over said dilator;
- removing said first dilator and needle and wire assembly to leave said tracheostomy tube in position in the patient's lumen;
- and
- inserting a first dilator assembly of a predetermined diameter into said tracheostomy tube in order to provide an air passage of initial size into said trachea lumen, said first dilator assembly including a first dilator and a first cannula tube, said first dilator being removable to leave in place said first cannula tube positioned in said tracheostomy tube upon removal of said first dilator.
A tracheostomy tube for installation into a tracheostoma in order to receive a cannula tube of various diameters, comprising:
- a multilayer tube formed of one or more sheets of resilient material wrapped into a coiled sheath or tube and adapted to be inserted into a tracheostoma, said multilayer tube having a variable diameter to receive various sizes of cannula tubes without removal of the multilayer tube.
