Embodiment Construction

[0020] In this specification, the terms "axial" and "radial" refer to figure 1 The longitudinal axis A of the device is shown. The terms "proximal" and "distal" refer to the delivery aperture of the device. The terms "top", "bottom", "upper" and "lower" refer to the correct position of the device as shown in the drawings.

[0021] The invention is more particularly applicable to devices of the single-dose powder type, such as the one shown in the accompanying drawings. Of course, other types of nasal powder delivery devices are also applicable.

[0022] The device 100 shown in the figures comprises a container 110 containing a single dose of powder. Devices with containers holding more than one dose are possible. Likewise, a device comprising several containers each containing a single dose is possible.

[0023] Fitted on said container 110 is a nasal delivery tip 120 for insertion into a user's nostril. The nasal delivery head includes a delivery aperture 121 . Deliver...

Abstract

The invention relates to a nasal powder delivery device (100), comprising a container (110) containing at least one dose of powder, a nasal delivery head (120) for insertion into a nostril of a user, said nasal delivery head having a delivery aperture (121), and an air discharge system (130) generating, upon actuation of said powder nasal delivery device (100), a flow of compressed air for delivering a dose of powder into said nostril through said delivery aperture (121), said air discharge system comprising an air chamber (131) arranged in a skirt (125) and a piston (132) which, when the device is actuated, sealingly slides in said air chamber (131) in order to compress the air contained in said air chamber (131), said piston (132) being rigidly connected to an actuating member (140), in which, before actuation, at least one breakable bridge (200) is provided between said skirt (125) and said actuating member (140), wherein each breakable bridge (200) is formed on said skirt (125) and cooperates with a radial projection (210) formed on said actuating member (140), each radial projection (210) having an axial extension greater than that of the respective breakable bridge (200) and forming an inclined axial ramp on either side of the respective breakable bridge (200).

Description

technical field [0001] The present invention relates to nasal powder delivery devices. Background technique [0002] Nasal powder delivery devices are well known. They typically include a container containing one or more doses of powder, a delivery device, and a nasal delivery tip for insertion into a user's nostril, the nasal delivery tip including a delivery aperture. The conveying device usually includes an exhaust system. When the delivery device is activated, a dose of powder is delivered into the nostrils of the user. [0003] The drawbacks of these devices of the prior art are related to the reliability of the device, especially when activated. Therefore, a breakable bridge is generally provided between the two movable parts abutting against each other on actuation to build up energy in the user's hand and to define in a predetermined manner the threshold of force required to achieve actuation. However, these breakable bridges have the disadvantage of sometimes le...
