Breathing assistance apparatus

摘要

Breathing assistance apparatus includes a gases supply unit adapted to, in use, deliver a stream of pressurised gases from an outlet. The gases supply unit is adapted to vary the pressure of the stream of pressurised gases. A supply path includes a flexible self-supporting gases transportation pathway having a first end connected to the outlet so that the gases transportation pathway receives the stream of gases and conveys the gases to a patient. A patient interface is connected to the second end of the gases transportation pathway receives a stream of gases. At least one sensor measures at least one information parameter of the supply path. A control system associated with the gases supply unit receives the information parameter. The control system contains reference data, and compares the received data to reference data, and determines a supply path based on the comparison.

1. Breathing assistance apparatus comprising:
a gases supply unit adapted to, in use, deliver a stream of pressurised gases, an outlet for supplying, in use, the pressurised gases stream to a supply path including a flexible self-supporting gases transportation pathway and a patient interface; a control system associated with the gases supply unit adapted to receive data of at least one information parameter from at least one sensor, said at least one information parameter comprising a parameter of a flow of gases from said outlet, said control system containing reference data, said control system comparing said received data to said reference data, and determining said supply path based on said comparison, wherein said reference data comprises a plurality of flow parameter profiles and individual flow parameter profiles corresponding to individual supply paths and wherein determining said supply path based on said comparison comprises identifying at least one of the plurality of flow parameter profiles that substantially aligns with said received data.
