ABSTRACT:
An apparatus for inserting a laryngeal mask has a holder portion, a pair of clamp bars which extend forwards from the holder portion and which are adapted to hold therebetween in a pinching manner a tube connecting portion provided on an outside surface of the laryngeal mask. The pair of clamp bars are connected together at their front ends to thereby form an abutment portion which is adapted to abut a front end of the outside surface of the laryngeal mask. The apparatus also has a band piece which extends from the abutment portion along the clamp bars towards the holder portion and which can be pulled towards the holder portion. Another apparatus for inserting a laryngeal mask has a pair of clamp bars which are arranged to hold therebetween a tube connecting portion provided on an outside surface of the laryngeal mask, a pivot pin for pivotally supporting the clamp bars at approximately intermediate portions thereof such that front ends and rear ends of the clamp bars can respectively move towards and away from each other, and an abutment portion which is formed at the front ends of the clamp bars so as to abut a front end of the outside surface of the laryngeal mask.
