| titleOfInvention | Inhalation device with a pumping unit |
| abstract | The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to an inhalation device for delivering a nebulised medically active aerosol for inhalation therapy comprising a pumping unit, said pumping unit comprising a riser pipe (2), a hollow cylindrical part (3) having an interior space configured to receive an upstream end portion (21) of said riser pipe (2), said cylindrical part (3) being moveable on the riser pipe (2), wherein the cylindrical part and the riser pipe form a pumping chamber having a variable volume, wherein a gap (4) is present between a lateral outside surface (22) of the upstream end portion (21) of said riser pipe (2) and a lateral internal surface (31) of said cylindrical part (3), wherein a seal (1) is present between the outside surface (22) of said riser pipe (2) and the internal surface (31) of said cylindrical part (3), thus physically bridging said gap (4), and wherein the seal (1) has a cap-like shape configured to fit around the upstream end portion (21) of the riser pipe (2), having at least one opening (11) for providing a fluid connection between an interior space of said riser pipe (2) and said pumping chamber, and wherein at an interior surface (14) of the seal (1), at least one interior protrusion (16) is present which is configured to be received by at least one respective recess (23) of the riser pipe (2). |
