  • Patent number: 9610413
    Abstract: A powder medicament mouthpiece comprising at least one section of through suction tube (1) and a filter (2). One end of the suction tube is a medicament inlet, and the other end (16a) is a suction outlet. The filter (2) is arranged within the suction tube (1). The powder medicament mouthpiece can be connected to multiple models of dry powder inhalers to separate powder medicament from dry powder, and allows for significantly improved efficacy.

  • Patent number: 9339614
    Abstract: A filtering powdered medicament inhaler comprising a base (1) and an upper base (2). The upper base (2) has arranged therein a separator (62), which is connected at the bottom to a pressure groove (63). The upper base (2) has arranged thereon a hollow tube exterior connector (10) matching a suction tube (131). The hollow tube (19a) and a cavity (9) on one side of the separator (62) are interconnected via conduit (18), or, the hollow tube (19a) is extended for about 8 centimeters to form a mouthpiece. The upper base (2) has arranged in the cavity (9) thereof a filter (121). The base (1) is provided with an external base cover (72) which covers a press-button (5a) so as to reduce air flow into the cavity (9). The medicament inhaling conduit of the inhaler is relatively sealed and allows for rapid entrainment of a sufficient dosage of powdered medicament.

  • Patent number: 8978645
    Abstract: This invention provides an aerosolized inhaler which enables the drug powder to aerosolize within the inhaler by breathing in the air, comprising the main body (11) and the mouthpiece connector (12) connected thereupon, wherein the inhaler the main body (11) has drug holding opening (1), which connects with the vortex passage, and the vortex passage connects with the mouthpiece (9) on the mouthpiece connector (12). It has many obvious advantages as increasing the inhalation rate, pushing more drug granule to reach to the lower respiratory tract and even into the alveolus; and meanwhile, keeping the drug from being blown out of the inhaler when the users breathes out, preventing from cross inflection and minimizing the side effect of the drug to the whole body, and obviously lightening the burden on the users.
