Cannula-based vibrating mesh nebulizer

Abstract

Systems and methods for providing respiratory therapy are disclosed. One device includes a nasal cannula comprising at least at one nasal prong, tubing and a breathing gas conduit. The nasal prong hasa proximal tip and a distal end connected to the breathing gas conduit. The breathing gas conduit has an inlet port, an outlet port, and a walled flow path connecting the inlet and outlet ports, suchthat the conduit directs the breathing gas from the tubing to the proximal tip of the nasal prong. A nebulizer is secured to the nasal cannula and operable to aerosolize a medicament via a vibratingmesh. The vibrating mesh is secured to the nasal cannula and is positioned adjacent to the breathing gas conduit such that the aerosol is entrained with the breathing gas at proximal tip of the nasalprong.

Background technique [0003] Patients with respiratory diseases may be given supplemental breathing gases, such as oxygen, for example, to aid in breathing. These breathing gases are typically provided from a source of breathing gas (e.g., an oxygen tank) and delivered through a delivery device (e.g., a nasal cannula) that is coupled to the source of breathing gas and inserted into the nasal cavity of the patient for the delivery of breath. with gas. Separately, certain respiratory medications are administered by inhalation, wherein the medication or drug is nebulized by a nebulizer and delivered to the patient's lungs by inhalation.
