Abstract
Abstract An apparatus for establishment of an airway in transtracheal intubation via the cricothyroid membrane is disclosed in which the design integrates within a single unit a curvilinear needle with cutting blade, stylet, syringe and non-metal airway cannula in an over-the-needle position. The integrated design enhances quick and accurate placement of the airway in both emergency and non-emergency applications.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
106 words
An apparatus for performing transtracheal intubation via the cricothyroid membrane comprising, in combination: a syringe means comprising at least one hollow barrel with a distal end adapted for attachment of integral apparatus means; a plunger means slideably disposed within said hollow barrel of said syringe means; a flexible stylet means slideably disposed within said barrel of said syringe means; a hollow curvilinear needle means integrally attached to said distal end of said syringe means, said needle means having at its distal end a sharpened edge to serve as a cutting blade; and a non-metal hollow tube airway means which is slideably disposed over said needle means.
Claim 2
Independent Claim
106 words
An apparatus for performing transtracheal intubation via the cricothyroid membrane comprising, in combination: a syringe means comprising at least one hollow barrel with a distal end adapted for attachment of integral apparatus means; a plunger means slideably disposed within said hollow barrel of said syringe means; a flexible stylet means slideably disposed within said barrel of said syringe means; a hollow curvilinear needle means integrally attached to said distal end of said syringe means, said needle means having at its distal end a sharpened edge to serve as a cutting blade; and a non-metal hollow tube airway means which is slideably disposed over said needle means.
Claim 3
Dependent Claim
41 words
