Schematic of the stoma attachment.
(a) Orientation of the stoma attachment during breathing. (b) Orientation of the stoma attachment when the button valve has been depressed to enable tracheoesophageal speech. The drain cap is also open to show how accumulated water within the device can be drained. All dimensions are in inches.
