Emergency cricothyrotomy tube insertion
First Claim
Patent Images
1. A device for inserting an emergency airway comprising:
- a sharp central trocar for piercing tissue, said sharp central trocar supporting a cricothyrotomy tube;
a translation mechanism connected to said trocar for applying a predetermined distal force to said sharp central trocar for moving said sharp central trocar from a cocked state to a tissue-piercing state, said translation mechanism concurrently moving the cricothyrotomy tube supported by said sharp central trocar from a non-inserted state to an inserted state;
a user-controlled activation element for activating said translation mechanism to effect movement of said sharp central trocar and the cricothyrotomy tube; and
,a hand-held housing supporting said sharp central trocar, said translation mechanism and said activation element;
said sharp central trocar and the cricothyrotomy tube adapted for use in a crico-thyroid region of a patient.

Abstract
The present invention is drawn to a criocthyrotomy tube insertion device which provides for the accurate delivery and placement of a cricothyrotomy tube. The force applied to insert the cricothyrotomy tube and the duration of the application of the force are predetermined to assure safe and accurate insertion of the cricothyrotomy tube. The device is easily positioned to ensure deliver of the cricothyrotomy tube in the crico-thyroid region.

12. A device for inserting an emergency airway comprising:
-
a hand-held housing having a distal opening, a sharp central trocar in said housing, said sharp central trocar supporting a cricothrotomy tube, said sharp central trocar being movable between a distal protracted position extending a predetermined distance distal of said distal opening of said housing and a proximal retracted position within said housing, a translation mechanism coupled to said cutting sharp central trocar, said translation mechanism having an active state in which said translation mechanism forces said sharp central trocar and said cricothyrotomy tube from said retracted position to said protracted position, an operator-controlled trigger operatively connected to said translation mechanism for initiating said active state of said translation mechanism, said distal opening of said housing being adapted to be placed over a crico-thyroid region of a patient. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
