The present invention relates to the field of mechanical-ventilation devices, in particular devices that enable drugs to be fed into the airflow, generated by the ventilation device and directed to the respiratory pathways of a patient, using an aerosol dosing device and/or nebulizer. Specifically, the invention relates to an inhalation chamber (1) to be built into a circuit of a mechanical-ventilation respiratory device (100) through which a gas stream is to pass, said inhalation chamber (1) consisting of two portions on either side of the longitudinal axis (A) thereof, and comprising openings that lead into the inner space (Vi) thereof, wherein two openings (10, 11) are to be connected to the circuit of the respirator, i.e. one opening (10) for the ingress of the gas stream and the other opening (11) for the egress of the gas stream, and one opening (12) that is to receive a nebulizer (2), characterized in that the openings (12, 13) for receiving the aerosol dosing device (3) and the nebulizer (2) are both provided in a single portion of said inhalation chamber (1) with respect to the longitudinal axis (A).
An inhalation chamber (1) to be built into a circuit of a mechanical-ventilation respiratory device (100) and to be crossed by a gas stream, the inhalation chamber (1) comprising an upper portion on a side of a longitudinal axis (32) and a lower portion on an other side of the longitudinal axis (32) and comprising a first opening, a second opening, a third opening, and a fourth opening, which open on an internal volume (30), the first and the second opening (10, 11) being for connection with a circuit of a respirator and defining the longitudinal axis therebetween, the first opening (10) for entry of a gas stream, the second opening (11) for exit of the gas stream, the third opening (12) for receiving a pressurized metered-dose inhaler (3) and the fourth opening (13) for receiving a nebulizer (2), the chamber having sections of which one larger section (36) has a width (L) greater than widths of all other sections of the inhalation chamber, and one narrower section (37) has a narrower width (e) than the larger section, the third opening (12) being provided in the narrower section (37) and the fourth opening (13) being provided in the larger section (36), wherein the third and the fourth openings (12, 13) for receiving the inhaler (3) and the nebulizer (2) are both entirely comprised on a same one of the upper and the lower portion of the inhalation chamber (1) with respect to the longitudinal axis (32), and wherein the fourth opening (13) is located downstream of the third opening (12) with respect to the longitudinal axis (32).
A mechanical-ventilation respiratory device (100) comprising:
