Embodiment Construction

[0019] inhaler ( figure 1 ) consists of three basic parts, an inlet piece A with a lid, a piece B with a surface on which the blister strips are placed, and a blister strip storage piece C. These parts are connected to each other and can be opened independently.

[0020] entry piece( figure 2 ) includes components 1, 2 and 3. Part 1 locks part 2 in it, and part 2 locks part 3 in it.

[0021] Part 1 is the outer part of the inlet piece and has an air opening at its base.

[0022] Part 2 is a cylinder with a wider base. The top end of the cylinder has an opening 4 which serves as an outlet for the powder to exit the device. In the cylinder there is an arrangement 5, which may be helical or otherwise shaped, through which the aspirated powder with air is expelled. At the base of part 2 half of the end of array 5 is blocked by surface 6 .

[0023] Part 3 is also a cylinder with a wider top. The interior of part 3 is divided into two chambers 7 and 8 by a vertical plane 9...

Abstract

An inhalation device that absorbs medicaments in dry powder form contained in blisters of specially designed single-dose blister strips. The device comprises an inlet piece (A), an area with support surfaces (B) and one or more storage areas (C). Additionally, single-dose blister strips are also described. It consists of two pieces (17, 20) which are held together in such a way that the powder can be inhaled when they are separated.

Description

technical field [0001] The present invention relates to an inhaler for absorbing medicaments in dry powder form and to specially designed single dose blister strips for use with said inhaler. Background technique [0002] Inhalation devices currently in use can be divided into two types as follows: [0003] 1. The drug powder is stored in a container, and a measured amount of powder can be taken out from the container by a specific mechanism. For example, EP0069715 describes a device in which the powder is measured in a given amount by means of openings located in a rotatable disc which are directed by the rotating disc into air ducts or channels through which air is drawn in. [0004] 2. The measured amount of drug powder can be separately stored in a specific container. For example, GB2242134 describes a device using a flexible band to define a plurality of pockets, each containing a dose of medicament that can be inhaled. The device comprises a chamber in which the tap...
