Laryngeal mask airway device and method for administering a medicament through a laryngeal mask airway device

A laryngeal mask airway device, comprising:

• an airway tube having a proximal end and a distal end;
• a laryngeal mask placed at the distal end of the airway tube, wherein the distal end of the airway tube opens inside the laryngeal mask, wherein the laryngeal mask is configured to seal around a laryngeal inlet of a patient;
• a connector placed at the proximal end or close to the proximal end of the airway tube, wherein the connector is in fluid communication with the laryngeal mask through the airway tube and is configured to be connected to a ventilation equipment;
• a movable element placed in the laryngeal mask and configured to steer a tip of a catheter passing through the airway tube when said catheter protrudes in the laryngeal mask;
• a control element;
• a motion transmission device operatively connected to the movable element and to the control element to move the movable element and to steer the tip of the catheter by acting on the control element;
• wherein the control element is mounted on the proximal end of the airway tube,
• wherein the motion transmission device comprises a cord and a leaf spring, and
• wherein the movable element is mounted to an end of the leaf spring and an extremity of the cord is linked to the movable element or to said end of the leaf spring so that the leaf spring is elastically deflected by pulling the cord.

A laryngeal mask airway device, comprising:

• an airway tube having a proximal end and a distal end;
• a laryngeal mask placed at the distal end of the airway tube, wherein the distal end of the airway tube opens inside the laryngeal mask, wherein the laryngeal mask is configured to seal around a laryngeal inlet of a patient;
• a connector placed at the proximal end or close to the proximal end of the airway tube, wherein the connector is in fluid communication with the laryngeal mask through the airway tube and is configured to be connected to a ventilation equipment;
• a movable element placed in the laryngeal mask and configured to steer a tip of a catheter passing through the airway tube when said catheter protrudes in the laryngeal mask;
• a control element;
• a motion transmission device operatively connected to the movable element and to the control element to move the movable element and to steer the tip of the catheter by acting on the control element,
• wherein said motion transmission device comprises a stem and said movable element comprises a hooked tip, said stem being jointly attached at its distal end to said hooked tip, whereby said stem and said hooked tip are made in one piece as a single item,
• wherein said stem is moveably arranged in the laryngeal mask airway device such that it moves at least along an axis parallel to the longitudinal axis of the airway tube when the control element is operated,
• wherein said hooked tip is moveably arranged in the laryngeal mask airway device such that it rotates about an axis when the stem moves, and
• wherein the motion transmission device comprises a linking interface jointly attached to a proximal end of said stem, whereby said stem, said hooked tip and said linking interface are made in one piece as single item, said linking interface being linked to said control element, whereby actuating said control element causes movement of said linking interface, of said stem, and rotation of said hooked tip;
• and
• a casing defining the proximal end and supporting the connector and the control element;
• wherein the control element is mounted on the proximal end of the airway tube.

• a movable element placed in the laryngeal mask and configured to steer a tip of a catheter passing through the airway tube when said catheter protrudes in the laryngeal mask;
• a control element;
• a motion transmission device operatively connected to the movable element and to the control element to move the movable element and to steer the tip of the catheter by acting on the control element;
• wherein the control element is mounted on the proximal end of the airway tube,
• wherein said motion transmission device comprises a stem and said movable element comprises a hooked tip, said stem being jointly attached at its distal end to said hooked tip, whereby said stem and said hooked tip are made in one piece as a single item, and
• wherein said hooked tip comprises a flexible section jointly attached to the distal end of the stem, said flexible section being thinner with respect to the stem.
