A mechanically deployable upper airway stent is disclosed along with a method of using same. The stent comprises a central tube having an inner chamber and openings on its surface. A linkage rod is housed within the central tube and is provided with branched spokes that pass through the openings. In the un-deployed state the branched spokes are contained within the central tube. Deployed spokes are preferably aligned in groupings along the central tube. The outer ends of the spokes of each grouping connect to a rib. The un-deployed stent is inserted into the nasal passageway and positioned relative to occluding anatomic structures. Upon deployment, the ribs along with web members extending between the ribs move outwardly from the central tube and press upon the tissues of the pharyngeal cavity. Spaces between the extended spokes permit the passage of air along the stent and maintain airway patency.

A method and infrared sensing device for determining the concentration of alveolar alcohol in a breath sample exhaled by a subject into an infrared sensing device. The presence of alcohol from the upper respiratory tract of the subject is detected by continuously monitoring alcohol and carbon dioxide, normalizing alcohol values with respect to carbon dioxide, calculating a difference between normalized alcohol concentration and carbon dioxide concentration over time, integrating (summing) the difference, and comparing the integrated difference with a threshold. This technique accurately and consistently detects the presence of mouth alcohol in the sample before the presence of carbon dioxide which originates in deep lung breath.

The invention discloses a multifunctional respiratory therapy system for hospital and family environments. The multifunctional respiratory therapy system comprises a control unit, a ventilation unit and an oxygen generation unit; due to self oxygen generation through an oxygen supply unit, the problem that the existing respiratory therapy equipment completely depends on an external oxygen source is solved; low/high flow oxygen therapy, intelligent oxygen supply control and non-invasive positive-pressure mechanical ventilation therapy functions are integrated into a whole; corresponding therapeutic working modes can be started according to different requirements of different stages of respiratory diseases of patients; and therefore, seamless switching and multiple purposes by one machine invarious therapeutic schemes can be realized.

Ciliary motion in the upper airway is the primary mechanism by which the body transports foreign particulate out of the respiratory system. The ciliary beating frequency (CBF) is often disrupted with the onset of disease. Current imaging of ciliary motion relies on microscopy and high speed cameras, which cannot be easily adapted to in-vivo imaging. M-mode optical coherence tomography (OCT) imaging is capable of visualization of ciliary activity, but the field of view is limited. The present invention features the development of a spectrally encoded interferometric microscopy (SEIM) system using a phase-resolved Doppler (PRD) algorithm to measure and map the ciliary beating frequency within an on face region. This novel high speed, high resolution system allows for visualization of both temporal and spatial ciliary motion patterns.
