Abstract: A device for dispensing a fluid product, having a body with a dispensing orifice, two removable reservoirs each containing a single dose of fluid product, a dispensing mechanism, and an actuating mechanism. The reservoirs are closed before the dispensing device is actuated. The body has a mechanism for opening each reservoir and adapted to open the reservoirs during actuation of the device. The reservoirs each form a sealed unit which is separate from said body, each reservoir filled with a respective fluid product and hermetically sealed before installed in the body. The body has a receiving mechanism for lateral installation of the reservoirs in the body.

Abstract: Assembly for dispensing a fluid product, having a nasal fluid product dispenser with a reservoir containing the fluid, a dispensing member, and a dispensing head on the dispensing member, the dispensing head provided with a dispensing orifice, a remote mobile device attached to the user's head, such as an earpiece, the nasal device and the remote mobile device attached to the user's head each having an orientation sensor, such as an accelerometer or a gyroscope. The orientation sensors cooperate to determine the position of the nasal dispenser in the nostril. The nasal dispenser has an indicator visible when the dispenser is in the nostril, to guide the user towards an optimal orientation of the nasal dispenser in the nostril. The nasal dispenser having an electronic module and automatic actuation mechanism that automatically actuates the nasal device when the orientation sensors detect that the nasal dispenser is arranged in an optimal position.

Abstract: A device for nasal delivery of fluid product, having a reservoir containing a fluid, a delivery member, and a delivery head on the delivery member, and the delivery head provided with a delivery opening. The nasal device has a camera for determining the spatial positioning of the nasal device inside a nostril, the camera determining the vertical tilt angle and the lateral tilt angle between the longitudinal axis of the nasal device and an axis of the face identified by a plurality of reference points, the orientation of the axis with respect to the nostril identical to whatever the position of the user, a positioning indicator for guiding the user towards an optimal orientation of the nasal device inside the nostril, and an electronic module and automatic actuation mechanism for automatically actuating the nasal device when the camera determines that the nasal device is disposed in an optimal position.

Abstract: A fluid dispenser device having a body (1) with a dispenser orifice (2) and a perforator element (4), the body containing a reservoir (10) with at least two doses of fluid and having a proximal axial opening closed by a membrane (30) and a distal axial opening closed by a piston (20) to dispense one dose of fluid on each actuation. The reservoir is axially movable relative to the body between a rest position in which said perforator element does not pass through the membrane and a dispensing position in which the perforator element passes through the membrane. A perforator spring (6) is provided to urge the reservoir towards the rest position, and the membrane is adapted to close after each actuation, when said perforator element withdraws from the reservoir.
