Abstract

An inhalation-synchronized fluid dispenser device having a body (10; 10′) provided with a mouthpiece (400), a fluid reservoir (100) containing a fluid and a propellant gas being mounted to slide axially in the body (10; 10′), a metering valve (200) including a valve member (210) assembled on the reservoir (100) for selectively dispensing the fluid. The device includes an actuator element (500, 500′, 500″; 550) movable and/or deformable between a non-actuation position and an actuation position; an inhalation-controlled trigger system including an inhalation-sensitive member (60, 61; 65, 66) deformable and/or movable under the effect of inhaling and when deformed and/or moved, moving and/or deforming the actuator element (500, 500′, 500″; 550) from its non-actuation position towards its actuation position; an electronic dose counter (1000); and a signal-transmitter (1100) for communicating, in particular communicating remotely, information relating to the actuations of the device.

First claim

The invention claimed is:

1. An inhalation-synchronized fluid dispenser device comprising a body provided with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas mounted to slide axially in said body, a metering valve including a valve member assembled on said reservoir for selectively dispensing the fluid, said device further comprises:
an actuator element that is movable and/or deformable between a non-actuation position in which said metering valve ( 200 ) cannot be actuated, and an actuation position in which said metering valve can be actuated;
an inhalation-controlled trigger system including an inhalation-sensitive member that is deformable and/or movable under the effect of inhaling, said inhalation-sensitive member, when deformed and/or moved, moving and/or deforming said actuator element from the non-actuation position towards the actuation position;
an electronic dose counter; and
signal-transmitter means for communicating information relating to actuations of the device; and
wherein an actuator member is assembled on the reservoir on the end that is axially remote from said metering valve, said actuator member comprising a hollow sleeve that is axially movable relative to said reservoir between a rest position and a primed position, a spring arranged between a bottom of the reservoir and a closed top edge of said hollow sleeve, such that when the user presses manually on said actuator member so as to move the actuator member towards the primed position, said spring is compressed, so as to transmit an axial force to said reservoir.

2. A device according to claim 1 , wherein a laterally-actuated pusher is mounted to pivot on the body between a rest position, and a working position in which the laterally-actuated pusher axially moves said actuator member into the primed position.

3. The device according to claim 1 , wherein said signal-transmitter means is configured for communicating remotely the information relating to the actuations of the device.

4. An inhalation-synchronized fluid dispenser device comprising a body provided with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas mounted to slide axially in said body, a metering valve including a valve member assembled on said reservoir for selectively dispensing the fluid, said device further comprises:
an actuator element that is movable and/or deformable between a non-actuation position in which said metering valve ( 200 ) cannot be actuated, and an actuation position in which said metering valve can be actuated;
an inhalation-controlled trigger system including an inhalation-sensitive member that is deformable and/or movable under the effect of inhaling, said inhalation-sensitive member, when deformed and/or moved, moving and/or deforming said actuator element from the non-actuation position towards the actuation position;
an electronic dose counter; and
signal-transmitter means for communicating information relating to the actuations of the device; and
wherein said body includes an opening that connects the mouthpiece to the inside of the body, said opening being closed at the start of inhaling by a check valve, such that the inhalation flow due to inhaling initially passes mainly to the trigger system.

5. A device according to claim 4 , wherein said check valve is opened when said actuator moves towards the actuation position.

6. The device according to claim 4 , wherein said signal-transmitter means is configured for communicating remotely the information relating to the actuations of the device.

7. An inhalation-synchronized fluid dispenser device comprising a body provided with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas mounted to slide axially in said body, a metering valve including a valve member assembled on said reservoir for selectively dispensing the fluid, said device further comprises:
an actuator element that is movable and/or deformable between a non-actuation position in which said metering valve ( 200 ) cannot be actuated, and an actuation position in which said metering valve can be actuated;
an inhalation-controlled trigger system including an inhalation-sensitive member that is deformable and/or movable under the effect of inhaling, said inhalation-sensitive member, when it is deformed and/or moved, moving and/or deforming said actuator element from the non-actuation position towards the actuation position;
an electronic dose counter; and
signal-transmitter means for communicating information relating to the actuations of the device; and
wherein said actuator element is a blocking element that, in the non-actuation position, co-operates firstly with the body and secondly with the reservoir so as to prevent said reservoir from moving axially in the body; and
wherein said blocking element comprises an axial extension having a bottom end that is fastened radially and axially relative to said body, and a top end that co-operates with said reservoir in the non-actuation position.

8. A device according to claim 7 , wherein said inhalation-controlled trigger system includes a piston that slides in a chamber between a rest position and an inhaling position.

9. A device according to claim 8 , wherein said blocking element is assembled on a rod ( 540 ) that is secured to the piston ( 65 ), so that during inhaling, said rod moves radially, deforming and/or moving said axial extension towards the actuation position.

10. The device according to claim 7 , wherein said signal-transmitter means is configured for communicating remotely the information relating to the actuations of the device.

11. An inhalation-synchronized fluid dispenser device comprising a body provided with a mouthpiece, a fluid reservoir containing a fluid and a propellant gas mounted to slide axially in said body, a metering valve including a valve member assembled on said reservoir for selectively dispensing the fluid, said device further comprises:
an actuator element that is movable and/or deformable between a non-actuation position in which said metering valve ( 200 ) cannot be actuated, and an actuation position in which said metering valve can be actuated;
an inhalation-controlled trigger system including an inhalation-sensitive member that is deformable and/or movable under the effect of inhaling, said inhalation-sensitive member, when it is deformed and/or moved, moving and/or deforming said actuator element from the non-actuation position towards the actuation position;
an electronic dose counter; and
signal-transmitter means for communicating information relating to the actuations of the device; and
wherein said actuator element is a locking element that, in its non-actuation position, enables said valve member of the metering valve to move axially in the body, together with said reservoir, preventing said metering valve from being actuated when said reservoir is moved axially in the body without inhaling.

12. A device according to claim 11 , wherein, during inhaling, said locking element is moved and/or deformed to prevent the valve member from moving axially relative to the body.

13. A device according to claim 12 , wherein said inhalation-controlled trigger system includes a piston that slides in a chamber between a rest position and an inhaling position.

14. A device according to claim 13 , wherein said locking element is secured to a rod that is secured to the piston, so that during inhaling, said rod moves radially, moving said locking element towards the actuation position in which the locking element prevents said valve member of the metering valve from moving axially when said reservoir is move
