Abstract
According to various embodiments, a tracheal tube may include a drug delivery system for nebulizing drug to droplets within a particular drop size range. The drug delivery system may include an integral nebulizer located towards a distal end of the tracheal tube. The nebulizer may comprise a micropump and may be in fluid communication with a drug delivery lumen, which in turn may be coupled to a system for monitoring the delivery of drug to the nebulizer. The nebulizer may be sized and shaped to be accommodated within a lumen that runs alongside a main respiratory lumen of the tracheal tube.
Claims20
A medical device comprising:
- a tracheal tube adapted to be inserted into a patient airway comprising a first lumen for delivering respiratory gases to the patient;
- a second lumen formed in a wall of the tracheal tube and running substantially parallel to the first lumen, wherein the second lumen is configured to transfer a drug to a distal end of the second lumen;
- and
- a nebulizer disposed proximate the distal end of the second lumen, wherein the nebulizer is capable of nebulizing the drug.
A system for drug delivery comprising:
- a tracheal tube adapted to be inserted into a patient airway comprising a first lumen for delivering respiratory gases to the patient;
- a second lumen formed in a wall of the tracheal tube and terminating at a distal end of the tracheal tube;
- a membrane comprising a plurality of orifices disposed in a distal end of the second lumen;
- an actuating device configured to oscillate the membrane;
- and
- a controller coupled to the actuating device.
A medical device comprising:
- a tracheal tube adapted to be inserted into a patient airway comprising a first lumen for delivering respiratory gases to the patient;
- a second lumen formed in a wall of the tracheal tube and running substantially parallel to the first lumen, wherein the second lumen is configured to transfer a liquid to a distal end of the second lumen;
- a liquid entry port coupled to the second lumen;
- a flexible membrane seal disposed in the second lumen at a location proximal to the liquid entry port;
- and
- a pressure transducer coupled to the second lumen at a location proximal to the flexible membrane seal.
