Appl. No.:

15/937462

Inventors:

- Bellevue WA, US
Mark K. Kuiper - Seattle WA, US
Daniel Howard Lieberman - Issaquah WA, US
Lucas Wagner - Duvall WA, US

International Classification:

F17C 7/04

Abstract:

Disclosed embodiments include apparatuses for compressing dry ice. In an illustrative embodiment, an apparatus for compressing dry ice includes: a hollow cylinder; a post disposed coaxially in the cylinder; a piston defining an opening therein and being slidably disposed in the cylinder, the opening slidably receiving the post therein; a biasing device operatively coupled to the piston; an inlet port connectable to a source of liquid carbon dioxide and configured to introduce liquid carbon dioxide into the cylinder, the inlet port being further configured to expand liquid carbon dioxide to dry ice and to gaseous carbon dioxide; and an openably closable lid positionable among a first closed position configured to vent gaseous carbon dioxide from the cylinder, a second closed position configured to leakably close the cylinder to permit carbon dioxide flakes to be compressed in the cylinder, and an open position.

International Classification:

A61M 16/10
A61M 16/00

Abstract:

Described embodiments include a therapeutic oxygen supply apparatus. The apparatus includes at least two components, including an intake manifold component configured to receive concentrated oxygen, a compressor component configured to compress concentrated oxygen, an oxygen tank component configured to store concentrated oxygen, a patient manifold component configured to supply concentrated oxygen, or a control structure component configured to route a flow of concentrated oxygen. A sensor circuit acquires data indicative of a respective operational state of the at least two components. A rule-based engine selects a next operational state of a component in response to (i) the acquired data indicative of the respective operational states of the at least two components and (ii) a rule database having at least one rule responsive to an objective providing a therapeutic flow of oxygen to the patient. A configuration manager circuit generates a control signal implementing the selected next operational state.

International Classification:

F25J 1/00
F25J 1/02

Abstract:

Devices and systems for dry ice production are described, including a lid structure sized for placement over a storage container, an input tube sized to traverse a first opening in the lid structure and forming a flow conduit for pressurized carbon dioxide into the storage container, a vent tube sized to traverse a second opening in the lid structure and forming a flow conduit for gaseous carbon dioxide, a first end of the vent tube sized to fit into the storage container, a lower vent tube sized to fit in the storage container, the lower vent tube coupled to the first end of the vent tube and having openings to vent gaseous carbon dioxide from the storage container and into the vent tube.

International Classification:

A61M 16/06
A61M 16/00
A61M 16/08

Abstract:

In some embodiments, a rebreathing oxygen supplementation device includes an enclosure including an internal surface of a size and shape to entirely cover the nasal region of a patient and including an edge region of a size and shape to reversibly mate with a skin region of the patient surrounding the nasal region. The device can include at least one tubular structure affixed to the enclosure, the tubular structure including a proximal region with a first aperture positioned adjacent to a nostril of the patient and at least one distal region with a second aperture, the tubular structure positioned to permit gas flow between an interior of the enclosure and a region exterior to the tubular structure, and an aperture in the proximal region positioned adjacent to the patient's nostrils.
