Tracheostomy valves and related methods

Номер: US20120012116A1
Принадлежит: Passy Muir Inc

The embodiments of the present tracheostomy valves include a flexible diaphragm abutting a rib shaped substantially as a flat plate. Opposite the rib, the diaphragm abuts a boss and forms an uninterrupted seal therewith. As the tracheostomized patient inhales, the diaphragm bends about the rib, interrupting the seal and allowing air to flow smoothly into the valve. The features of the various embodiments contribute to a positive seal at all times except during inhalation, and low resistance to airflow through the valve during inhalation.

An allergen exposure system includes a mixing chamber, delimited by walls and distinct from the air inlet duct and from the exposure room in which the patients are situated. A mixing between a stream of allergen particles from an allergen injection device and a flow of air devoid of allergens which has passed through a filtration device, occurs through a phenomenon of microturbulence in this mixing chamber which forms a widening with respect to the air inlet duct and makes it possible to obtain a flow of air laden with allergen particles which is injected into the exposure room through at least one diffusion outlet so that it can be inhaled by the patients. This invention is of benefit to medical and pharmaceutical research in the field of allergy study. 1.

PORTABLE HALOTHERAPY DEVICE FOR AEROSOLIZING SALT

Номер: US20210077756A1
Принадлежит: INFINITY SALT AIR MACHINE, LLC

A portable halotherapy device includes a housing, a grinding chamber with a grinding blade that breaks apart dry granular salt into salt particles small enough for halotherapy, an air duct routing air to the chamber, a fluid conduit, and a high-speed exhaust fan. Ambient air flows through the air ducts into the grinding chamber to produce a first air current. Air is diverted from the first air current upward, in a second air current, through the fluid conduit and the fan. The first air current helps move dry granular salt around and against the grinding chamber, breaking it into small salt particles. The second air current is arranged relative to the first air current such that small salt particles, but not larger pieces, are carried as salt aerosol upward through the fluid conduit and fan for distribution to the environment, thereby facilitating a halotherapy session. 1. A portable halotherapy device , comprising:(a) one or more housings that may be coupled together to define a single operational unit;(b) a grinding chamber, having an interior with a moving grinding blade therein, that is disposed within the one or more housings and that breaks apart dry granular salt in the interior thereof into salt particles small enough to be used for halotherapy;(c) an air intake assembly, including one or more air ducts that each route ambient air from outside the one or more housings into the interior of the grinding chamber;(d) a fluid conduit that is disposed within the one or more housings and that has an inlet at a first end and an outlet at a second end, wherein the conduit extends upward from the first end, wherein the inlet is in fluid communication with the interior of the grinding chamber; and(e) an exhaust unit, the exhaust unit including a high-speed fan disposed within the one or more housings at the second end of the fluid conduit and in communication with the outlet thereof;(f) wherein the moving grinding blade and the high-speed fan together operate to produce ...
