CA 2312998

An apparatus for and a method of ensuring the fit of a face mask to the face of a patient, the apparatus comprising: a face mask (11; 49; 89) having an inlet (11a; 49a; 89a) through which gas can be inhaled; and a sensor (19; 67; 99) for measuring the flow rate of gas drawn through the inlet (11a; 49a; 89a) of the face mask (11; 49; 89); wherein the fit of the face mask (11; 49; 89) is determined by monitoring the flow rate of gas drawn through the inlet (11a; 49a; 89a) of the face mask (11; 49; 89) upon inhalation by a patient, with the face mask (11; 49; 89) being considered satisfactorily to fit the patient when a substantially regular inhalation waveform is achieved.

L'invention porte sur un appareil et un procédé permettant d'adapter un masque sur le visage d'un patient. L'appareil comprend: un masque facial (11; 49; 89) pourvu d'un orifice d'admission (11a; 49a; 89a) par lequel le gaz peut être inhalé; et un capteur (19; 67; 99) permettant de mesurer le débit du gaz entraîné dans l'orifice d'admission (11a; 49a; 89a) du masque facial (11; 49; 89). L'adaptation de ce masque (11; 49; 89) est déterminée par le contrôle du débit du gaz entraîné dans l'orifice d'admission (11a; 49a; 89a) du masque lors de l'inhalation, le masque (11; 49; 89) s'adaptant relativement bien sur le visage du patient lors de la génération d'une forme d'onde d'inhalation régulière.
