Problems solved by technology

[0006] However, breathing aids of this type are often bulky, since they include complex, for example tortuous, internal gas circuits in order to ensure good cooling of the micro-fans and in order to meet the ventilation requirements, in particular to limit head loss and to ensure good ventilation. Ventilation performance and patient safety

Embodiment Construction

[0076] Figure 1-Figure 8 An embodiment of a rigid housing 1 according to the invention for a respiratory assistance device or a medical ventilator 10 is shown, comprising a motorized micro-blower 2 also called a turbine or compressor.

[0077] According to the invention, the rigid shell 1 is formed in two parts, namely a first half-shell 1a and a second half-shell 1b, which in a sealed / fluid-tight manner are rigidly connected to each other, in other words schematically in the form of two capsules or two-lobed shell petals.

[0078] if possible from figure 1 It can be seen that, in the illustrated embodiment, the housing 1 also has a substantially cuboid shape. More generally, the rigid shell 1 comprises:

[0079] - the motor compartment 3 in which the motorized micro-blower 2 is arranged;

[0080] - an air inlet compartment 11 comprising an air inlet opening 12 in fluid communication with the ambient atmosphere and also in fluid communication with the motor compartment 3...

Abstract

The invention relates to a respiratory assistance device (10) comprising a rigid inner housing (1) comprising a motor compartment (3) in which a motorized micro fan (2) is arranged. The housing (1) isformed by a first and a second half-housing (1a, 1b) rigidly connected to each other in a sealed manner. The rigid housing (1) comprises: an air inlet compartment (11) comprising an air inlet opening(12) in communication with the atmosphere, the air inlet compartment (11) also being in fluid communication with the motor compartment (3) via at least one air outlet opening (13); a gas outlet compartment (14) comprising a gas supply opening (15), the gas outlet compartment (14) being supplied with gas by means of a motorized micro fan (2); an oxygen circuit (16) comprising an oxygen inlet (17)and at least one oxygen outlet (18) in fluid communication with the motor compartment (3); and a ventilation circuit (19) including an air outlet (21) and an air inlet (20) formed in the air inlet compartment (11). The invention also relates to a device for supplying breathing gas to a patient.

Description

technical field [0001] The present invention relates to a breathing aid, namely a medical ventilator / ventilator for delivering a flow of oxygen-enriched air for the treatment of one or more respiratory diseases in humans, the medical ventilator being equipped with a multifunctional housing, the The multifunctional housing includes a gas circuit and a motorized micro-blower for delivering breathing gas such as air or oxygen-enriched air. Background technique [0002] Respiratory assistance devices, also known as medical ventilators, are used to deliver gases at non-zero flow rates and / or at superatmospheric pressures (>1atm) in order to assist a specific patient in respiratory function such as air or oxygen-enriched air. [0003] These breathing aids draw in ambient air and deliver it to the patient at a given pressure using a motorized miniature fan, also known as a compressor or turbine. The air drawn in by the micro-blower during operation of the micro-blower motor is...
