Abstract
An intubation device having a main body portion defining a first longitudinal axis, a distal tip portion coupled to the main body portion and defining a second longitudinal axis, and a deflection system having a single drive member extending within at least the distal tip portion and coupled thereto. The deflection system is operable to exert a tensile force upon the distal tip portion to articulate the distal tip portion relative to the main body portion between a resting position and a positive incline position and a negative incline position.
Claims18
An endotracheal intubation device comprising:
- a generally elongated main body portion defining a first longitudinal axis (B-B);
- a distal tip portion coupled to said main body portion at an interface, said distal tip portion defining a second longitudinal axis (C-C), said interface comprising a generally rigid connection to establish said distal tip portion in a rest position defined by a predetermined initial inclination of said second longitudinal axis (C-C) relative to said first longitudinal axis (B-B), said predetermined initial inclination being in the range of about 10 degrees to about 20 degrees measured from said first longitudinal axis (B-B);
- and
- a deflection system extending within at least said distal tip portion and coupled thereto, said deflection system operable to exert a force upon said distal tip portion to articulate said distal tip portion relative to said main body portion between said resting position and a positive incline position, said positive incline position defining a first angle between said first longitudinal axis (B-B) and a positive inclined longitudinal axis (C′-C′), said first angle being greater than said predetermined initial inclination, said deflection system further operable to exert a force upon said distal tip portion to articulate said distal tip portion relative to said main body portion between said resting position to a negative incline position, said negative incline position defining a second angle between said first longitudinal axis (B-B) and a negative inclined longitudinal axis (C″-C″) which is negative with respect to the first longitudinal axis (B-B), said second angle being less than said predetermined initial inclination;
- said distal tip portion comprising a plurality of notches formed in at least one side thereof, said plurality of notches facilitating articulation of said distal tip portion relative to said main body portion;
- in said rest position distal tip extends straight along said second longitudinal axis (C-C), and in said positive incline position said distal tip extends straight along said positive inclined longitudinal axis (C′-C′) at said first angle.
