Tracheostomy valves and related methods

Номер: US20120012116A1
Автор: Andrew J. Scherer, Rex O. Bare
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.

In one embodiment the result is achieved mechanically. In another embodiment, the result is achieved by aerosol formulation. In a preferred embodiment, the invention assures the result when aerosol is delivered directly to the airways distal of the ventilator circuit. The devices eliminate the dosage variability that ventilator systems engender when aerosols are introduced via the ventilator circuit. The treatment also concentrates the therapeutic agent specifically at affected sites in the lung such that therapeutic levels of administrated drug are achieved without significant systemic exposure of the patient to the drug. The invention further provides a dose control device to govern this specialized regimen.

FLUIDIC-CONTROLLED RESERVOIR CANNULA

Номер: US20170000966A1
Автор: Pacas Rebecca E., Tiep Brian L.
Принадлежит:

A reservoir cannula is described that has a static fluidic control structure, in that it does not employ a membrane or other moving parts. Furthermore, the reservoir is open to ambient air instead of being sealed. In use, the reservoir cannula enables storage of oxygen and oxygen-rich gas in a storage chamber as well as in and around the patient's nasal passages and nasopharynx, which enables high volume oxygen delivery to the patient early in the next inhalation. Consequently, patients using this delivery mode can carry a smaller and lighter portable oxygen container for ambulatory oxygen, because lower flow oxygen is required to meet their oxygenation needs. In addition, patients requiring a higher flow of oxygen can achieve oxygenation levels previously achieved only by high flow mask or high flow nasal oxygen systems. 1. A cannula for controlling delivery of gas , comprising:an outer shell having an outer surface exposed to ambient air and an inner surface defining a reservoir chamber;an exhaust aperture extending through the outer shell to the reservoir chamber and having an open surface area dimension;a static structure disposed within the reservoir chamber and including a fluidic controller having a nasal port; anda nasal prong fitted to the nasal port and extending through the exhaust aperture, wherein the nasal prong has an outer area dimension which is less than the open surface area dimension of the exhaust aperture to permit gas to escape from the cannula.2.

Принадлежит: Leland Stanford Junior University

Devices, systems, and methods for treating chronic rhinosinutisits (CRS) are described herein. The devices can have a guide member defining at least one lumen therethrough. A drug delivery component is advanced through the lumen to deliver a substance to the sino-nasal cavity of a patient. Once the drug delivery component is positioned at the desired area in the sino-nasal cavity, a user actuates the system to deliver the substance to the target area. Actuation of the system delivers the substance to the middle meatus, osteo-meatal complex, or other areas within the sino-nasal cavity of the patient.
