Abstract
A laryngeal mask including a dome and an airway tube extending from a proximal passage through the dome. The dome has a periphery about its base including at least one receptacle. An inflatable cuff of flexible material has a first longitudinal edge and a second longitudinal edge. The longitudinal edges are joined to form a tube forming the cuff. The cuff substantially encircles the periphery of the dome. The mask has at least one buttress adjacent to the periphery at a distal portion of the dome. The tube is fused adjacent the buttress of the dome, and the fusing is below a posterior surface of the dome wherein, upon deflation of the cuff, the buttress upturns the cuff to facilitate insertion of the laryngeal mask into a patient.
Claims8
A laryngeal mask comprising:
- a dome, said dome having a periphery about its base, said periphery including at least one receptacle;
- an airway tube extending from a proximal passage through said dome;
- an inflatable cuff of flexible material, said flexible material has a first longitudinal edge and a second longitudinal edge, said first longitudinal edge and said second longitudinal edge are joined to form a tube for said cuff, said cuff substantially encircles said periphery of said dome;
- at least one buttress adjacent said periphery at a distal portion of said dome;
- and
- a fusing of said tube forming said cuff, said fusing being adjacent to said buttress of said dome, said fusing is below a posterior surface of said dome wherein, upon deflation of said cuff, said buttress upturns said cuff to facilitate insertion of said laryngeal mask into a patient.
A laryngeal mask comprising:
- a dome, said dome having a periphery, said periphery including at least one channel and at least one distal buttress;
- an airway tube extending from a proximal passage through said dome;
- an inflatable cuff of flexible material, said flexible material has a first longitudinal edge and a second longitudinal edge, one of said longitudinal edges includes a semi-rigid bead, said semi-rigid bead is held by a complementary receptacle on said other longitudinal edge to form a tube for said cuff, said cuff substantially encircles said periphery of said dome;
- and
- an adhesive, said adhesive holds said tube forming said cuff adjacent to said buttress of said dome, said adhesive is below a posterior surface of said dome, wherein, upon deflation of said cuff, said buttress upturns said cuff to facilitate insertion of said laryngeal mask into a patient.
A laryngeal mask comprising:
- a dome, said dome having a periphery;
- an airway tube extending from a proximal passage through said dome;
- an inflatable cuff of flexible material, said flexible material has a first longitudinal edge and a second longitudinal edge, said first longitudinal edge includes at least one semi-rigid bead, said semi-rigid bead is held by a complementary semi-rigid channel on said second longitudinal edge to form, when joined, a tube for said cuff and at least a partial buttress, said cuff substantially encircles said periphery of said dome;
- and
- an adhesive, said adhesive holds said joined semi-rigid bead and complementary channel adjacent said buttress of said dome, said adhesive provides a substantially planer posterior surface between said dome and said cuff wherein said adhesive is below a posterior surface of said dome, and upon deflation of said cuff, said buttress upturns said cuff to facilitate insertion of said laryngeal mask into a patient.
