Embodiment Construction

[0036] The present disclosure generally relates to the capture of certain materials suspended in or carried by a gas that aggregate into a liquid state after removal by specialized filtration and collection in a capture vessel. Specific materials to be removed and collected in the capture container may include, for example, water vapor, other liquids in a vapor state, other aerosolized liquids, aerosolized medical solutions and suspensions, and the like. In some embodiments, the removal and capture of materials may be in the context of delivery of therapeutic gases to a patient (eg, a patient receiving breathing gas from a ventilator circuit, which may include nitric acid and other therapeutic gases). For example, implementations may include removing such specific materials from a sample of breathing gas passed through the inspiratory limb prior to passing the sample through the sampling device. The sampling device can be configured to continuously confirm at least the dosing ...

Abstract

A trap bowl is provided to accumulate liquid droplets from a filter, as a liquid content. The trap bowl includes a transparent vertical prism. The transparent vertical prism includes a face that formsa vertical transparent surface facing against a content of the section. The face can provide a first angle of total reflection when content of the section is a type of gas, and a second angle of total reflection when the content of the section is the liquid content. A light source may emit a light beam incident on the face at an angle of incidence. The angle of incidence results in reflection ofthe light beam, striking the light receiver, when the face has the first angle of total reflection, and results in refraction of the light beam, missing the light receiver, when the face has the second angle of total reflection.

Description

[0001] Cross References to Related Applications [0002] This application claims a U.S. patent entitled APPARATUS AND METHOD FOR DETECTING LIQUID LEVEL IN A CLEAR ORPARTIALLY CLEAR CONTAINER, filed May 3, 2016 Priority to Application No. 62 / 331,117, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The present disclosure generally relates to the removal (e.g., filtration) and collection in containers or traps of liquid particles from a sampled inspiratory flow of a patient breathing circuit attached to a ventilator and / or therapeutic gas delivery system ( For example, inhaled nitric oxide gas delivery system). Background technique [0004] Many patients may benefit from receiving a therapeutic gas (eg, nitric oxide gas) in the inspiratory respiratory flow. The therapeutic gas may be delivered, for example, from a breathing circuit attached to a ventilator (eg, constant flow ventilator, variable flow ventilator, high freq...
