Definitions
- NOZZLE FOR USE IN MOUTH-IKHALIKG FOR AEROSOL MEDICAMENTS
- the present invention relates to an aerosol nozzle, comprising a socket provided with a seat to house a hollow stem of an aerosol dispensing pressurized can.
- Inhalation is the preferred system for delivering medicament particles into the lungs.
- pressurized cans containing the medicament and a propellant are used, the cans being provided with a metering valve which when manually operated dispenses metered doses of propellant-medicament mixture which atomizes through a nozzle as a finely powdered spray into the mouth of a patient.
- Said device is designed to favour the inhaling of a greater number of active particles and to avoid spraying the aerosol directly onto the mucosa of the oropharynx in order to safeguard the user against side effects deriving from direct spray into the mouth.
- the device has an expansion chamber shaped to create, by virtue of the speed at which the aerosolized material is expelled by the dispenser, a vortex flow in which the particles remain in suspension for sufficient time to enable them to discharge their kinetic energy and allow substantial evaporation of the propellant, with a consequent reduction in the size and in the velocity of the particles, leading to a more efficient intrapulmonary delivery, while large size particles are centrifuged onto the walls of the chamber, to deposit on them.
- the device comprises a body with a seat for housing a can provided with a stem for operating the can dispensing valve, a chamber for the collection and expansion of the aerosol dispensed by a discharge nozzle on the can, and a mouthpiece communicating with said chamber and projecting outwards from said body.
- the body has a substantially flat shape and the chamber is delimited by a curved wall, into a first peripheral portion of which there opens the inner end of the mouthpiece, and in a second peripheral portions of which, opposite the first, there is an aperture from which two walls extend outwards from the chamber to converge towards the can discharge nozzle and define a duct, the central plane of which is inclined to the central plane of said mouthpiece.
- Figure 1 is a perspective view of the inhaler device
- Figure 2 shows one of the two shells forming the device, viewed in the direction indicated by the lines 2-2 of Figure 1
- Figure 3 and 4 are sections through the inhaler device on the lines 3-3 and 4-4 of Figure 1.
- an aerosol nozzle having the shape of a T consisting of an upper horizontal bar and a vertical stem, said stem comprising a socket with a seat for housing a hollow stem of a pressurized can, characterized in that the hole of the vertical stem of the nozzle through which a dose of medicament discharged from a metering valve finds its way into the expansion chamber is inclined with respect to the hollow stem of the pressurized can.
- Figure 5 is a front view of the T shaped nozzle
- Figure 6 is a side view of the T shaped nozzle
- Figure 7 is a top view of the T shaped nozzle
- Figure 8 is a section view of the nozzle along lines A-A of the Figures 5 and 7 , showing the socket provided with a seat to house a hollow stem of a pressurized can and the inclined hole through which a dose of medicament discharged from the valve enters into the expansion chamber .
- the nozzle (1) is shaped as a T, consisting of an upper bar composed by two fins (2, 3) to be housed and retained in two seats provided in the two shells forming the device and of a vertical stem (4) shorter than the horizontal upper bar.
- the vertical stem (4) comprises a socket (5) provided with a seat to house a hollow stem of a pressurized can.
- the hole (6) is inclined with respect to the plane B normal to the axis of the vertical stem (4).
- the discharged aerosol passes through the inclined hole (6) and emerges through the orifice (7) as a cone whose axis is inclined with respect to the plane B.
- the axis of the hole and of the emerging aerosol cone forms with the plane B an angle in the range of 20 to 30° and preferably of 27°.
- the internal diameter of the hole (6) is in the range of 0.40 to 0.55 mm and is preferably of 0.42 to 0.52 mm.
- the inclination of the hole is designed in a manner that the aerosol cone issuing from the nozzle orifice passes through the duct defined by the two walls 11 and 21 of Figures 3 and 4 extending outwards from the expansion chamber and converging towards the exit hole of the nozzle.
- the inclination of the hole is designed in a manner that the axis of said aerosol cone corresponds with the central plane of the ducts.
