Title: FAN-DRIVEN RESPIRATORY ASSISTANCE APPARATUS WITH REVERSED FAN-MOTOR ASSEMBLY
Abstract:
The present invention relates to a fan-driven respiratory assistance apparatus (1) comprising a fan (3) for pressurising gas to be delivered to a patient (11), and a motor arrangement (5) for driving said fan. The fan comprises a gas inlet opening (2), a gas outlet opening (4), and an impeller (12) for generating a flow of gas from the gas inlet opening to the gas outlet opening, via said impeller. The motor arrangement (5) comprises a motor (8) for rotating the impeller (12) so as to generate said flow of gas. The impeller (12) and the motor arrangement (5) are arranged in relation to each other such that the direction of flow into the impeller (12) is directed away from the motor arrangement (5).
