Definitions
- the present invention relates to the field of powder inhalation devices. More specifically, it relates to inhalation devices triggerable by aspiration.
- the present invention aims to offer an improved inhalation device compared to those of the prior art.
- Mode 1 ( Figures 1 to 6) comprises a device having very approximate shape of a disc, the 2nd guide ( Figures 7 to 1 1) having substantially a tubular shape.
- Figures 1, 2 and 5 illustrate a device in the armed position
- the needle (15) is positioned above the capsule (14) to be pierced
- valve (7) is in the high position so that there is a seal between the chamber (4 ') located above the valve (7) and the chamber (4 ") located below the valve
- the patient applies his lips to the nozzle so as to hermetically seal the chamber located below the valve.
- the valve then moves downwards, a displacement of the order of 2 mm being sufficient to release the top bellows part from the sliding shell.
- the force of the part 16 on the part 17 is no longer balanced by the presence of the valve behind the lug: the removal of the valve causes the lug 17 to move towards the axis of revolution of the sliding shell by its own elasticity.
- the part 16 is then no longer blocked by 17, which causes the top bellows 5 part to move downward under the action of the bellows spring.
- the needle being integral with the high bellows 5, it descends at the same time. It first pierces the upper membrane of the cell (14), then secondly the lower membrane of the cell.
- Figures 3 and 4 show the device in the storage position. In this configuration, the end piece 2 is obstructed.
- the needle 15 remains housed in the passage 13 containing the capsule 14 last drilled.
- the height of the device is reduced, eg less than 40 mm.
- the two springs 21, 22 are compressed.
- FIG. 6 shows the device following its activation " .
- the two springs 21, 22 are relaxed.
- the upper part 4 ′ of the chamber is at its minimum volume.
- the powder has been expelled from the capsule 14. To put the device in storage position, simply compress it in a vertical direction.
- Figures 7 and 10 illustrate a tubular device in the armed position.
- the configuration and operation of this variant are very similar to that of the "disk" variant previously exposed. Besides its height, it differs in that the mouthpiece is placed under the device.
- FIGS 8 and 9 show the device in the storage position.
- FIG. 11 shows the device following its activation.
- the invention is not limited to the devices described above.
- the means for releasing the contents of the capsules are not necessarily perforating members.
- the capsules can be opened by crushing and tearing their membrane.
- the external shape of the housing is not necessarily cylindrical.
