Abstract
An integrated oxygen supply device that is configured to generate oxygen continuously and release the oxygen non-continuously is provided. In some embodiments, the oxygen generated by the integrated oxygen supply device is stored in a porous material with the integrated oxygen supply device. The delivery of the oxygen produced by integrated oxygen supply device to a patient, in those embodiments, is controlled. In some embodiments, the control of the delivering oxygen is according one or more breathing patterns. The breathing pattern(s) may or may not be a current breathing pattern of the patient. For example, in one embodiment, the breathing pattern is a predetermined breathing pattern with a specified inspiration period followed by a specified expiration period.
Core Innovation
The invention relates to an in-home respiratory device that generates oxygen from ambient air using an air separation unit and delivers oxygen to a user. The respiratory device includes an air separation unit, a gas conditioning unit, and a gas delivery unit, where the air separation unit receives ambient air and outputs oxygen, and the gas conditioning unit receives the oxygen and receives ambient air and outputs blended gas for delivery to the user by the gas delivery unit.
The air separation unit and the gas conditioning unit are located within a same housing of the respiratory device. A compression unit compresses ambient air for injection into the air separation unit, and the compression unit is controllable so that a workload of the compression unit is adjustable based on a preset threshold. The respiratory device further includes a heat exchanger arranged between the compression unit and the air separation unit to facilitate heat exchange between a medium around the compression unit and a medium around the air separation unit.
A heat communication is arranged between the heat exchanger and the gas delivery unit to transmit heat to the gas delivery unit for conditioning gas delivered to the patient. The disclosed control concepts include oxygen release in a pulsing mode and controllable oxygen concentration modes, including selectable ambient-air reception for the gas conditioning unit, including a mode that stops ambient-air reception. Feedback/control strategies are described to adjust compressor workload based on sensed delivered flow and/or oxygen fraction, including active treatment and recovery treatment.
Claims Coverage
The independent claims are clm-00001, clm-00005, clm-00008, and clm-00010. Across these claims, the inventive features focus on integrated air separation and gas conditioning in a same housing, blending oxygen with ambient air and delivering blended gas to a user, a controllable compression unit with workload adjusted based on a preset threshold, and a heat exchanger and heat communication arrangement to transfer heat for conditioning delivered gas, with additional disclosed operation modes for pulsed oxygen release and selectable ambient-air reception.
Integrated air separation and gas conditioning in a same housing
An air separation unit configured to receive ambient air and output oxygen; a gas conditioning unit configured to receive the oxygen, receive ambient air, and output blended gas; and a gas delivery unit configured to receive blended gas and facilitate a delivery of the blended gas to a user, wherein the air separation unit and the gas conditioning unit are located within a same housing of the respiratory device
Controllable compression unit with preset threshold workload adjustment
A compression unit configured to compress ambient air for injection into the air separation unit, wherein the compression unit is controllable such that a workload of the compression unit is adjustable based on a preset threshold
Heat exchanger between compression unit and air separation unit
A heat exchanger arranged between the compression unit and the air separation unit, wherein the heat exchanger is configured to facilitate heat exchange between a medium around the compression unit and a medium around the air separation unit
Heat communication from heat exchanger to gas delivery unit
A heat communication arranged between the heat exchanger and the gas delivery unit, wherein the heat communication is configured to transmit heat to the gas delivery unit for conditioning gas delivered to the patient
Processor-implemented controlling method for respiratory device
A method for controlling a respiratory device implemented by a processor in the respiratory device and comprising controlling the air separation unit to receive ambient air and output oxygen; controlling the gas conditioning unit to receive the oxygen, receive ambient air, and output blended gas; and controlling the gas delivery unit to receive blended gas and facilitate a delivery of the blended gas to a user, wherein the air separation unit and the gas conditioning unit are located within a same housing of the respiratory device
The claim set centers on an integrated respiratory device where ambient air is separated into oxygen, blended with ambient air within a same housing gas conditioning unit, and delivered as blended gas. The architecture includes a controllable compression unit with workload adjusted based on a preset threshold and a heat exchanger/heat communication arrangement that transmits heat to condition gas delivered to the patient. Additional refinements include pulsing release of enriched oxygen and controllable ambient-air reception for the gas conditioning unit.
