摘要:
The present disclosure relates to a sealing member for an inhaler and an assembly comprising the sealing member. The sealing member comprises a sealing lip. The assembly for an inhaler comprises a first part, a second part, and the sealing member which comprises the sealing lip, wherein the first part and the second part are assembled to permit relative rotational movement between the first part and the second part, and wherein the sealing lip sealingly engages a surface of the second part in order to provide a seal between the first part and the second part.
摘要:
A mechanism for a drug delivery device, having a first and a second state, including an engagement preventing member, and a blocking member having a blocking feature and an engagement element which is engagable with the blocking member. The blocking member is configured to engage with the engagement element in a non-linear movement, thereby moving the blocking feature is moved from a first position to a second position in an arc shaped movement. In the first state of the mechanism, the engagement preventing member is configured to prevent an engagement of the blocking member with the engagement element by covering the engagement element, and wherein, in the second state of the mechanism, the engagement element is free from the engagement preventing member such that the blocking member is enabled to engage with the engagement element.

A pharmaceutical composition suitable for use in a dry powder inhaler comprising 70 mass %-99.5 mass % of pharmaceutically acceptable carrier suitable for use in dry powder inhalation formulation and 0.1 mass %-12.5 mass % of salmeterol xinafoate and 0.4 mass %-17.5 mass % of fluticasone propionate.
摘要:
The present disclosure refers to a dose counting mechanism for an inhalation device comprising a first state and a second state wherein the mechanism is alterable from the first state to the second state by a user's suction airstream. Further, the present disclosure concerns an inhalation device comprising said dose counting mechanism.
摘要:
An inhaler for powdery, in particular medical, substances is formed with a suction air channel, which leads to a mouthpiece. The inhaler also has a storage chamber for storing the substance and a linearly moving dosing chamber for apportioning a specified amount of substance from the storage chamber to a transfer point to the suction air flow. The aim of the invention is to obtain a structurally simple solution that makes it possible to eliminate adding an external air flow. To this end, a component of the suction air flow, which is located in the direction of extension of the dosing chamber, empties said dosing chamber.
摘要:
A metering device activated by a user induced airstream for an inhalation of a medicinal substance. The device includes: a closure cap; a piston; a mouthpiece; and an annular chamber disposed upstream of the mouthpiece. A storage chamber stores the substance which can be moved out of the storage chamber when the closure cap is removed. A metering rod for removing the medicinal substance out of the storage chamber into an emptying-standby position. In the emptying-standby position, the metering chamber is closed by the piston. The piston is displaceable by airstream into an emptying-release position. In the emptying-release position, a metering chamber is released and the substance removed by the suction airstream. The metering device includes an outer cylinder which accommodates an inner cylinder.

The present disclosure concerns an assembly for a drug delivery device (1)comprising a housing (3), a first abutment surface (64), a second abutment surface (21), and a detachable member (7) which is detachable from the housing (3) and attachable to the housing (3), wherein the assembly is configured such that, during detachment of the detachable member (7) from the housing (3) for an Nth time, N being a predetermined number, the first abutment surface (64) is brought into abutment with the second abutment surface (21), wherein the assembly is configured such that, when the first abutment surface (64) abuts with the second abutment surface (21), the detachable member (7) is enabled to be reattached to the housing (3) and, afterwards, the detachable member (7) is prevented from being detached from the housing (3).
摘要:
An assembly for a counter mechanism for a drug delivery device is described comprising a drive member, wherein the drive member is adapted and arranged to be rotated in a first rotational direction and to be prevented from rotation in a second rotational direction which direction is opposite to the first rotational direction, an advancing member adapted and arranged to be axially moved and rotated with respect to the drive member, wherein the advancing member is adapted and arranged to mechanically cooperate with the drive member such that the drive member is rotated in the first rotational direction, and a display member which is configured to count a number of doses and to display the counted number of doses, wherein the assembly is adapted and arranged such that rotation of the drive member in the first rotational direction is converted into a counting movement of the display member. Furthermore, a drug delivery device comprising the assembly is described.
摘要:
An inhalable pharmaceutical composition suitable for giving improved feedback to the patient about the inhalation of the metered doses in a range between 5 miligram and 10 miligram and suitable for use in a dry powder inhaler comprises 70 mass %-99.5 mass % of pharmaceutically acceptable carrier suitable for use in dry powder inhalation formulation and 0.5 mass %-30 mass % of one or two pharmaceutically active ingredient(s).
摘要:
A metering element for an inhalation device is provided. The metering element comprises a plurality of openings being configured to receive a substance, wherein at least one of the openings has a different size than at least one other opening. Furthermore, an assembly for an inhalation device is provided. The assembly comprises a metering element with a plurality of openings and a powder channel which comprises an opening, wherein an arrangement of the openings is adapted to the shape of the powder channel such that each opening extends into the opening of the powder channel for a different amount.
