Abstract
Abstract An apparatus for carrying out tracheostomy tube replacement includes the use of a specially constructed obturator having a central longitudinal opening. The central opening of the obturator allows the obturator to pass over a guide tube which has been left in place after removal of the old tracheostomy tube. The obturator also has an atraumatic rounded tip to make passage of the obturator and replacement tracheostomy tube assembly through the stoma and into the tracheal lumen safer and easier, guided by the emplaced guide tube.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
195 words
An obturator for use with a tracheostomy tube to facilitate replacement of the tracheostomy tube, comprising: a substantially cylindrical body having a distal end, intended to extend from the distal end of the tracheostomy tube when in use, and a proximal end, intended to extend from the proximal end of the tracheostomy tube when in use, said body being sufficiently flexible to permit it to easily assume the shape of the tracheostomy tube with which the obturator is intended to be used; a blunt, rounded, atraumatic tip disposed at the distal end of said body; a flange disposed at the proximal end of said body, the length of said body being selected such that when said flange abuts the proximal end of the tracheostomy tube with which the obturator is intended to be used, said tip extends from the distal end of the tracheostomy tube far enough to effectively form a blunt, rounded, atraumatic end to the tracheostomy tube; wherein a central longitudinal opening extends throughout said cylindrical obturator body, including said tip and said flange, such that, when in use, a guide tube can be inserted through the obturator by means of said opening.
Claim 2
Dependent Claim

An obturator for use with a tracheostomy tube to facilitate replacement of the tracheostomy tube, comprising: a substantially cylindrical body having a distal end, intended to extend from the distal end of the tracheostomy tube when in use, and a proximal end, intended to extend from the proximal end of the tracheostomy tube when in use, said body being sufficiently flexible to permit it to easily assume the shape of the tracheostomy tube with which the obturator is intended to be used; a blunt, rounded, atraumatic tip disposed at the distal end of said body; a flange disposed at the proximal end of said body, the length of said body being selected such that when said flange abuts the proximal end of the tracheostomy tube with which the obturator is intended to be used, said tip extends from the distal end of the tracheostomy tube far enough to effectively form a blunt, rounded, atraumatic end to the tracheostomy tube; wherein a central longitudinal opening extends throughout said cylindrical obturator body, including said tip and said flange, such that, when in use, a guide tube can be inserted through the obturator by means of said opening.
Claim 3
Dependent Claim
24 words
A tracheostomy kit, comprising: a tracheostomy tube; and an obturator in accordance with claim 1, sized and dimensioned for use with said tracheostomy tube.
Claim 4
Dependent Claim
49 words
A tracheostomy kit in accordance with claim 2, further including guide means, sized and dimensioned to permit passage through said opening in said obturator, for placement through a tracheostomy tube in place on a patient so as to guide the reemplacement of a new tracheostomy tube, when in use.
Claim 5
Dependent Claim
16 words
A tracheostomy kit in accordance with claim 3, wherein said guide means comprises a suction catheter.
