Embodiment approach

[0199] The ventilator 200 includes a housing 202 that is generally volute-shaped. The housing preferably comprises two parts 202a, 202b which are connected, for example mechanically and / or by means of ultrasonic welding. The casing 202 constitutes a fixed portion of the fan 200 . The ventilator 200 also includes a rotating portion including at least one impeller and a shaft, which are driven by an electric motor 208 . In one implementation, the motor 208 may be a brushless DC motor. In the illustrated embodiment, the ventilator is of the single stage type, although it is obvious that the ventilator could comprise two or more stages. Figure 6 to Figure 9 The rotating part of the ventilator 200 is not shown. According to a preferred embodiment, however, the inventive impeller 300 constitutes the rotating part of the inventive ventilator 200 .

[0200] The ventilator includes an air inlet 204 and an air outlet 206, which are preferably tubular. The air inlet 204 is arranged...

Abstract

The invention relates to a patient ventilation or breathing device and components therefore for use in all forms of respiratory apparatus ventilation systems including invasive and non-invasive ventilation, positive airway pressure therapy, Continuous Positive Airway Pressure (CPAP), and particularly Bi-Level therapy and treatment for sleep disordered breathing (SDB) conditions such as Obstructive Sleep Apnea (OSA), and for various other respiratory disorders and diseases. The invention particularly relates to a blower, to a blade, to a gasket, to a cable, to an impeller, to a gas inlet and inlet member, to an improved air path or fluid flow path and components thereof, and / or to a modular ventilation or breathing device as referred to above and particularly incorporating one or more of the other aspects of the invention.

Description

technical field [0001] The present invention relates to a patient ventilation device or breathing device and components thereof for use in all types of ventilation systems for respiratory equipment, including invasive and non-invasive ventilation, positive pressure ventilation therapy, continuous positive airway pressure (CPAP), especially dual Horizontal Therapy and Sleep Disordered Breathing (SDB) disorders such as Obstructive Sleep Apnea (OSA) and a variety of other breathing disorders and conditions. In particular, the present invention relates to ventilators, blades, gaskets, multiconductor wires, impellers, gas inlets and inlet elements, improved air paths or fluid flow paths and components thereof, and / or to modular as above The ventilating device or breathing device, in particular in combination with one or more other aspects of the present invention. Background technique [0002] Respiratory disorders and diseases such as Sleep Disordered Breathing (SDB) diseases s...
