PULSED OXYGEN CONCENTRATOR BOLUS GENERATION

摘要

A pulsed oxygen concentrator is provided. It comprises a selector for determining the desired mass of a gas bolus delivered to a user and at least one sieve bed having an internal gas and an internal gas pressure within a volume defined by the at least one sieve bed. At least one pressure sensor is operatively connected to the at least one sieve bed to measure the internal gas pressure of the sieve bed. At least one sensor operatively connected to the oxygen concentrator to measure at least one ambient atmospheric parameter is also provided and at least one temperature sensor is connected to the at least one sieve bed. At least one valve is in selective fluid communication with the at least one sieve bed and configured to regulate delivery of said internal gas to a user. A feed- forward control system is provided and has input parameters of the at least one pressure sensor, the at least one ambient atmospheric sensor or the at least one temperature sensor and the selector. At least one controlled output parameter is configured to control the at least one valve for delivering a bolus mass to the user.
