Laryngeal mask airway insertion guide

Claim 2

An insertion guide device for use in the insertion of a laryngeal mask airway (LMA) into the throat of a patient, wherein a LMA comprises a respiratory tube, a tube-connecting portion and a mask body, said insertion guide comprising: a unitary, elongated member, having a distal surface and a proximate surface defining a top end portion, a bottom end portion, and a curved portion, whereby said insertion guide conforms to the length and the contour of the respiratory tube, the tube-connecting portion and the mask body in order to removably engage the LMA upon its insertion into a patient's throat, wherein said elongated member includes first member means for removably engaging the tube-connecting portion, said first means extending from said proximate surface; second means for removably engaging the respiratory tube, said second means extending from said distal surface; and, third means for removably engaging the mask body integrally extending from said bottom end portion.

Claim 3

The insertion guide device according to claim 1, wherein elongated member is constructed of a flexible material having a shape-retaining memory.

Claim 4

The insertion guide device according to claim 1, wherein said third means comprises a scoop member having rounded, curved and flat surfaces for engaging a distal surface of the mask body.

Claim 5

The insertion guide of device according to claim 1, wherein said first means comprises a fulcrum member extending from and connecting to said proximate surface, including a curved surface for fitting the tube-connecting portion of the LMA, and projecting laterally from said elongated member.

Claim 6

The insertion guide device according to claim 4, wherein said second means comprises a holder member extending from and connecting to said distal surface of said elongated member at a point above said fulcrum member, having a curved surface for fitting the respiratory tube and said holder member projecting laterally in the same direction as said fulcrum member.

Claim 7

The insertion guide device according to claim 1, wherein said top end portion is a rod having a rounded end.

Claim 8

An insertion guide device for use in the insertion of a laryngeal mask airway (LMA) into the throat of a patient, wherein a LMA comprises a respiratory tube, a tube-connecting portion and a mask body, said insertion guide comprising: a unitary, elongated member,constructed of a flexible material having shape-retaining memory, having a distal surface and a proximate surface defining a top end portion, a bottom end portion, and a curved portion, whereby said insertion guide conforms to the length and the contour of the respiratory tube, tube-connecting portion and the mask body in order to removably engage the LMA, wherein said elongated member includes a fulcrum member depending from said proximate surface and projecting laterally from said elongated member, including a curved surface for fitting the tube-connecting portion; a holder member extending from and connecting to said distal surface of said elongate member at a point above said fulcrum member, said holder member depending from said distal surface and projecting laterally in the same direction as said fulcrum member, and having a curved surface for fitting the respiratory tube; and, a scoop member having rounded, curved and flat surfaces for engaging a distal surface of the mask body, said scoop forming an integral and terminal portion of said bottom end portion.

Claim 9

An insertion guide device for use in the insertion of a laryngeal mask airway (LMA) into the throat of a patient, wherein a LMA comprises a respiratory tube, a tube-connecting portion and a mask body, said insertion guide comprising: a unitary, elongated member,constructed of a flexible material having shape-retaining memory, having a distal surface and a proximate surface defining a top end portion, a bottom end portion, and a curved portion, whereby said insertion guide conforms to the length and the contour of the respiratory tube, tube-connecting portion and the mask body in order to removably engage the LMA, wherein said elongated member includes a fulcrum member depending from said proximate surface and projecting laterally from said elongated member, including a curved surface for fitting the tube-connecting portion; a holder member extending from and connecting to said distal surface of said elongate member at a point above said fulcrum member, said holder member depending from said distal surface and projecting laterally in the same direction as said fulcrum member, and having a curved surface for fitting the respiratory tube; and, a scoop member having rounded, curved and flat surfaces for engaging a distal surface of the mask body, said scoop forming an integral and terminal portion of said bottom end portion.

Claim 10

The insertion guide device according to claim 7, wherein said top end portion is a rod having a rounded end.

Claim 11

A method for inserting a laryngeal mask airway (LMA) into the throat of a patient, comprising the steps of: engaging said LMA with said insertion guide device according to claim 7; inserting said LMA and said insertion guide into the throat of a patient; using the holder and the scoop of said insertion guide device to bend the LMA, while simultaneously using the fulcrum to push the LMA down into the patient's throat; positioning the LMA so that it covers the larynx of the patient; disengaging the holder and the fulcrum from their respective points on the LMA; and, removing said insertion guide device from the throat of the patient, leaving the LMA in place.
