Abstract
An inhaler, preferably for insertion into a nostril, in particular a horse's nostril, with an inhalation valve, which has a movable valve element, whereby the valve element is designed in an annular manner and has an outer edge and an inner edge, whereby the valve element is fastened at the outer edge, the inner edge forms the boundary of an indentation of the valve element, and the inhalation valve has a valve body seat that corresponds to the inner edge.
Claims20
An inhaler for insertion into a nostril, comprising:
- an inhalation valve which has a valve body seat, and an annular valve element which is deflectable off of the valve body seat only at an inner edge, and a stop for limiting maximum deflection of the inner edge of the valve element,
- a discharge nozzle for producing an aerosol, and
- a chamber configured for taking in of the aerosol from the nozzle,
- wherein the chamber is arranged downstream from the discharge nozzle,
- wherein the stop is formed by an edge of an intake opening of the chamber,
- wherein the stop corresponds in shape and diameter to the inner edge of the valve element,
- wherein the valve element rests snugly on the stop in an open position of the valve, and
- wherein the valve element is secured on an outer edge remote from the discharge nozzle so that the outer edge remains fixed when the inner edge is deflected off of the valve body seat.
An inhalation valve for an inhaler, comprising:
- a movable annular valve element with an outer edge and an inner edge,
- a valve body seat for the valve element,
- a fastening means circumferentially fastening the valve element for securing an outer edge of the valve element in position on the valve body seat, and
- a stop for limiting maximum deflection of the inner edge of the valve element, wherein the stop is formed by an edge of an intake opening of a chamber configured for taking in of an aerosol,
- wherein the outer edge of the valve element is snugly fastened all the way around by the fastening means and the inner edge is unsecured so that the inhalation valve opens only on the inner edge of the valve element by being deformed away from the valve body seat, and
- wherein the valve body seat has a sealing edge forming a through passage for guiding-through of a discharge nozzle.
