Abstract
An anatomical simulator useful in training proper tracheostomy and nasogastric tube placement and tracheostomy tube cuff inflation is disclosed. The simulator includes a simulated trachea and simulated esophagus separated by a simulated tracheoesophageal wall. The simulated wall is flexible, such that when a tracheostomy tube is positioned therein and a cuff thereon is overinflated, the wall extends outwardly in the direction of the simulated esophagus.
Claims16
A device for use in training proper tracheostomy tube placement and tracheostomy tube cuff inflation comprising:
- a simulator having a first surface simulating a surface of the human body at a cross-sectional plane taken therethrough, a second surface simulating an exterior surface of the human body, a first recessed area in said first surface defining a simulated trachea, a second recessed area in said first surface defining a simulated esophagus and a simulated tracheoesophageal wall, said wall comprising a flexible divider positioned between said first and second recessed areas, said wall adapted for movement in the direction of said simulated esophagus when subjected to the inflation pressure of a tracheostomy tube cuff positioned in said simulated trachea.
An observation model for use in training tracheostomy and nasogastric tube placement and proper tracheostomy cuff inflation, said model comprising a simulator having a simulated trachea, a simulated esophagus and a simulated tracheoesophageal wall, said wall comprising a flexible member dividing said simulated trachea and esophagus, said wall adapted for movement in the direction of said simulated esophagus when subjected to the inflation pressure of a tracheostomy tube cuff positioned in said simulated trachea.
A method for training proper tracheostomy tube placement and tracheostomy tube cuff inflation with an anatomical simulator having a simulated trachea, simulated esophagus and simulated tracheoesophageal wall therebetween, said wall comprising a flexible member, comprising the steps of:
- placing a first end of a tracheostomy tube into said simulated trachea of said observational model
- inflating a cuff positioned on said first end of said tracheostorny tube;
- and
- pressing said wall outwardly in the direction of said simulated esophagus in response to cuff over-inflation.
