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 integrated oxygen supply device that generates oxygen continuously and releases oxygen non-continuously using stored oxygen in a porous adsorbent. Concentrated oxygen is produced from ambient air in an air separation unit and is released to a user via a gas delivery unit. The released oxygen delivery is controlled based on breathing-pattern timing, including inspiration versus expiration timing, and/or using predetermined pulsing patterns.
The oxygen supply device includes an air separation unit configured to receive ambient air and output concentrated oxygen, and a gas conditioning unit configured to receive the concentrated oxygen and receive ambient air to output blended gas. The porous adsorbent storing the oxygen is described using adsorption materials such as Zeolite, MOF, and COF. Oxygen delivery is further conditioned so that the delivered gas meets target oxygen concentration (FiO2) and patient gas temperature and humidity.
A compression unit compresses ambient air for injection into the air separation unit, and the compressor workload is adjustable based on preset thresholds using feedback tied to delivered flow and/or oxygen fraction. Thermal management is provided by 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, with heat communication transmitting heat to the gas conditioning unit for conditioning gas delivered to the patient. This heat transfer is described as reducing power and complexity while conditioning delivered gas.
Claims Coverage
The patent includes two independent claims: an oxygen supply device and a method for controlling the oxygen supply device. Across these claims, the coverage centers on integrated in-housing air separation and gas conditioning, compressor workload adjustment based on a preset threshold, and thermal exchange and heat communication between the compression unit and gas conditioning.
Integrated air separation and gas conditioning in same housing
An oxygen supply device comprising an air separation unit configured to receive ambient air and output concentrated oxygen, and a gas conditioning unit configured to receive the concentrated oxygen and receive ambient air to output blended gas, wherein the air separation unit and the gas conditioning unit are located within a same housing of the oxygen supply device.
Controllable compressor workload based on preset threshold
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, and wherein the compression unit is configured to compress ambient air for injection into the gas conditioning unit.
Heat exchanger facilitating heat exchange between compression and air separation units
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 transmitting heat to gas conditioning unit
A heat communication arranged between the heat exchanger and the gas conditioning unit, where the heat communication is configured to transmit heat to the gas conditioning unit for conditioning gas delivered to the patient.
Processor-implemented control of air separation, conditioning, and delivery in same housing
A method for controlling an oxygen supply device implemented by a processor in the oxygen supply device, comprising controlling the air separation unit to receive ambient air and output concentrated oxygen, controlling the gas conditioning unit to receive the concentrated oxygen, receive ambient air, and output blended gas, controlling the gas delivery unit to receive blended gas and facilitate delivery to a user, wherein the air separation unit and the gas conditioning unit are located within a same housing of the oxygen supply device.
Adjusting compressor workload and managing thermal exchange and heat transfer
The method further comprising compressing ambient air for injection into the air separation unit; adjusting a workload of the compression unit based on a preset threshold; facilitating heat exchange between a medium around the compression unit and a medium around the air separation unit; and transmitting heat to the gas conditioning unit for conditioning gas delivered to the patient.
Overall, the independent claim coverage focuses on an oxygen supply device in which an air separation unit and a gas conditioning unit are located within the same housing, with blended gas delivery to a user, and on a compressor system whose workload is adjustable based on a preset threshold. The claims further require thermal management through a heat exchanger enabling heat exchange between the compression and air separation environments and heat communication transmitting heat to the gas conditioning unit for conditioning delivered gas.
