Abstract: A device (12) for sensing the respiratory air of a patient. The device includes a venturi tube (18) through which the patient inspires and expires, the tube having a constricted midportion (20). The tube also has an inspiration orifice (48), an expiration orifice (46), and a central orifice therebetween. An air mass flow sensor is positioned in the tube. A flow direction housing (24) is attached to the tube and has a channel (74) with an inspiration portion, an expiration portion, and a central portion therebetween. The housing also has an inspiration opening (68) providing communication between the tube inspiration orifice (88) and an end portion of the inspiration channel away from the central channel portion, an expiration opening (66) providing communication between the tube expiration orifice (88) and an end portion of the expiration channel portion, and a central opening (64) providing communication between the tube central orifice (44) and the central channel portion. This causes a flow of a portion of the respiratory air which the patient inspires to pass through the tube inspiration orifice and flow through the inspiration channel portion to the housing central opening, and a flow of a portion of the respiratory air which the patient expires to pass through the tube expiration channel portion to the housing central opening for return to the venturi tube at the tube constricted portion. A flow direction sensor is positioned in the inspiration channel portion and a flow direction sensor is positioned in the expiration channel portion to produce outputs responsive to the flow of respiratory air through the inspiration and expiration channel portions for determining if the respiratory air flowing through the venturi tube is inspired or expired air.

Abstract: The present invention relates to an apparatus for measuring the expiratory rate, comprising a measuring tube (13) partially obturated by a narrowing (17) of the interior of the tube, and a differential pressure sensor (27) coupled to the tube in order to measure the pressures in the tube on either side of the narrowing. The measuring tube (13) is removable and comprises on its external surface flexible annular seals (21) extending beyond the external surface and arranged on either side of the ports (18, 19) opening on either side of the narrowing. The measuring tube is intended to penetrate into a housing (11) of the apparatus having a diameter slightly larger than the external diameter of the measuring tube so that, in an abutment position (15) of the measuring tube in the housing, the seals define with the housing (11) and the external wall of the tube (14) annular chambers (23, 24) communicating respectively with two passages (25, 26) of the housing, which passages are connected to the pressure sensor.

Abstract: In the method proposed, the gas or gas mixture under analysis is passed through at least one support (5) in which at least one acoustic or ultrasonic transmitter or receiver cell (S1, S2) is located, preferably at an angle to the axis of the tube, to form a measurement path. The acoustic or ultrasonic transmitter or receiver elements (S1, S2) emit a pulsed acoustic signal, and the travel times of the pulses over the measurement path are determined. The variation in gas temperature along the at least one acoustic-transmission path is determined by, for instance, a temperature probe. The molecular weight is determined from the travel time of the acoustic pulses and the measured or assumed temperature. The device proposed is suitable for use in diagnosing deficiencies in the functioning of the lungs.

Abstract: A spirometric measurement device (10) includes an arrangement for computation of a dynamic BTPS correction factor, to compensate for temperature-related volume changes due to cooling of expired gas. The correction factor varies in time according to variation of temperature of a flow sensor (18). The temperature of the flow sensor (18) is accurately established by positioning a temperature sensor (20) downstream of the flow sensor (18). Autozeroing drift compensation is provided by addition of a PWM signal having an adjusted DC value. Resolution accuracy is increased beyond the capacity of an analog-to-digital converter used in the circuit by implementing a dithering procedure, wherein zero average noise is superimposed on the signal, or by implementing a modified dithering procedure wherein a sawtooth waveform is added to the flow signal, and oversampling the resultant signal.

Abstract: The present invention is a method for determining human expiratory flow rate, comprising a peak flow meter (36) and a zone calculator (49). The peak flow meter (36) is used to determine what the user's peak expiratory flow rate is in conjunction with medical data compiled on the zone calculator. The individual's peak expiratory flow rate and predetermined sub-optimal values are applied to the peak flow meter as color zone settings (38, 40, 42). The peak flow meter (36) thus set is ready for the individual to use to determine whether he is functioning in the peak expiratory flow rate color zone, or one of the sub-optimal expiratory flow rate color zones. The color zones correspond to specific remedial measures to be followed by the individual in case of sub-optimal expiratory flow rate.

Abstract: The apparatus is comprised of a connection conduit (1) comprising a mouth piece (2) at one of its extremities, a sound generator (3) provided with a nose (3a), as well as a digital time measuring unit (4). A tapping exhaust orifice (5) allows to tap a portion of the expired air. The orifice (5) has an opening which is adjustable by simply turning a cuff (6), screwed on the outside of the conduit (1). When the patient expires in the apparatus, only a well defined fraction of the airflow is directed towards the sound generator, the remainder being eliminated in the atmosphere through the tapping exhaust. The air flow which remains is directed through the sound generator wherein a well defined note is produced.
