Cricothyrotomy apparatus for establishing an emergency breathing path for patients experiencing upper respiratory obstruction. The apparatus here provided enables the user to perform the necessary operative steps on a patient in a relatively automatic and hidden fashion, so that the user is not aware of the fact that he is piercing the patient's throat and inserting a tube therein. This is accomplished by providing a housing enclosing a spring pressed surgical blade and spring pressed tube or according to a second embodiment, a combined spring pressed tube and blade. A release mechanism actuated by a simple pressure button on the exterior of the housing releases the knife and tube (or tube with piercing blade) for automatic positioning at the desired point in the throat of the patient. A location marker is further provided to insure desired positioning of the cut and tube on the patient.
Cricothyrotomy apparatus for establishing an emergency air breathing path for patients experiencing upper respiratory obstruction, said apparatus comprising:
A marking strip for identifying the point of incision when inserting a cricothyrotomy tube, said strip having a notch contoured to the shape of the bottom of the adam's apple;
A method of inserting a cricothyrotomy tube in a patient's throat in a fashion minimizing the awareness of the user of the procedure, said method comprising the steps of:
A method of rapidly identifying the point of incision for insertion of a cricothyrotomy tube in the neck of the patient, said method comprising the steps of forming a strip of material with a notch along one edge thereof;
