Abstract
A device for delivering a substance to an airway of a patient may include a laryngeal mask airway device, at least one substance delivery reservoir coupled with the laryngeal mask airway device for delivering the substance to the airway of the patient, and at least one conduit coupled with the laryngeal mask airway. The at least one conduit may have a proximal end configured to couple with a source of the substance residing outside the patient and a distal end in fluid communication with the at least one substance delivery reservoir.
Claims10
A device for delivering a substance to an upper airway of a patient, the device comprising:
- a laryngeal mask airway device, comprising;
- a breathing flow tube configured to extend through the patient's mouth to a distal end configured for placement at or adjacent the patient's larynx;
- a cuff attached to the distal end of the breathing flow tube;
- and
- an outlet in the cuff for ventilating the lungs;
- a branching conduit that branches from a single proximal end to two separate distal ends that extend in opposing directions along the cuff of the laryngeal mask airway device, wherein the proximal end is configured to couple with a source of the substance residing outside the patient;
- and
- two substance delivery reservoirs coupled with the laryngeal mask airway device, for delivering the substance to the airway of the patient, wherein each of the two substance delivery reservoirs is attached to a respective one of the two separate distal ends of the branching conduit in two separated locations on the cuff of the laryngeal mask airway device.
A method for delivering a substance to an upper airway of a patient, the method comprising:
- advancing a laryngeal mask airway device through the patient's mouth and into the upper airway of the patient, wherein the laryngeal mask airway device comprises;
- a breathing flow tube configured to extend through the patient's mouth to a distal end configured for placement at or adjacent the patient's larynx;
- a cuff attached to the distal end of the breathing flow tube;
- and
- an outlet in the cuff for ventilating the lungs;
- a branching conduit that branches from a single proximal end configured to couple with a source of the substance residing outside the patient to two separate distal ends that extend in opposing directions along the cuff of the laryngeal mask airway device;
- and
- two substance delivery reservoirs coupled with the laryngeal mask airway device, for delivering the substance to the airway of the patient, wherein each of the two substance delivery reservoirs is attached to a respective one of the two separate distal ends of the branching conduit in two separated locations on the cuff of the laryngeal mask airway device;
- connecting the proximal end of the branching conduit to the source of the sub stance;
- allowing the substance to pass from the source through the branching conduit to the two substance delivery reservoirs;
- and
- delivering the substance to the airway of the patient by allowing the substance to pass out of the two substance delivery reservoirs.
