The invention discloses a built-in endotracheal
catheter laryngeal
mask united ventilatory device for
general anaesthesia, and belongs to the field of medical apparatuses. The built-in endotracheal
catheter laryngeal
mask united ventilatory device comprises an outer
catheter, wherein a laryngeal
mask sac is fixedly arranged on the catheter wall on one side of the outer catheter; the catheter end on one side of the outer catheter is fixed on the inner wall of a plane of the laryngeal mask sac; an air guiding
pipe is fixedly arranged on the side wall of a curved surface of the laryngeal mask sac; an air sac is arranged at the end of the air guiding
pipe; a one-way air
inlet valve is fixedly arranged on the outer wall of the air sac; a control valve is fixedly arranged at one end close to theair sac, of the air guiding
pipe; a rubber tightening hole is fixedly formed in the side wall of the plane of the laryngeal mask sac; a swivel sleeve is fixedly arranged at the catheter end on the other side of the outer catheter; and an endotracheal catheter and a
phlegm eliminating catheter are arranged in an inner cavity of the outer catheter. According to the built-in endotracheal catheter laryngeal mask united ventilatory device disclosed by the invention, the situation that a great deal of
phlegm can block support gas to enter the body of a patient is avoided, ventilatory disorder is reduced, and the ventilatory effect is improved; and besides, the endotracheal catheter or the
phlegm eliminating catheter can be expanded and contracted into the laryngeal mask sac, so that the problemof laryngeal mask displacement generated when the patient is under different
body positions or the
body position is changed in the
surgery is solved, and the practicality of the built-in endotrachealcatheter laryngeal mask united ventilatory device is improved.
