Embodiment Construction

[0024] In this specification, the terms "axial" and "radial" especially refer to figure 2 in terms of the longitudinal orientation of the device shown. The terms "proximal" and "distal" refer to the dispensing orifice of the device.

[0025] The present invention is especially applicable to such as figure 2 Single-dose powder form device shown in . Obviously, other types of nasal powder dispensing devices are also contemplated.

[0026] figure 2 The device 100 is shown having a container 110 containing a dose of powder. Devices with containers containing more than one dose of powder are possible. Also, a device having multiple containers each containing a single dose is feasible.

[0027] Fitted on said container 110 is a nasal dispensing tip 120 for insertion into a user's nostril. The nasal dispensing head has a dispensing hole 121 .

[0028] The device 100 also has an air ram 130 that generates a flow of compressed air to dispense a dose of powder through the dis...

Abstract

A nasal powder dispensing device (100) having a container (110) containing at least one dose of powder, a nasal dispensing head (120) for insertion into a user's nostril, and an air pusher (130), the nasal dispensing head Having a dispensing hole (121), when the nasal powder dispensing device (100) is actuated, the air pusher generates a flow of compressed air to dispense a dose of powder into the nostril through the dispensing hole (121), the air pusher has The air chamber (131) and the piston (132), the piston slides hermetically in the air chamber (131) to compress the air in the air chamber (131), the nasal powder dispensing device (100) has the following properties: air pusher The pressure of the compressed air flow produced by (130) is greater than 0.7bar; and the volume of the air chamber (131) is greater than 1700mm 3 .

Description

technical field [0001] The present invention relates to a nasal powder dispensing device. Background technique [0002] Nasal powder dispensing devices are well known. It generally has a container for one or more doses of powder, a dispensing member and a nasal dispensing head for insertion into the nostril of a user, the nasal dispensing head having a dispensing aperture. The dispenser generally has an air pusher. When the dispensing device is actuated, a dose of powder is dispensed into the user's nostril. [0003] One drawback of these prior art devices relates to the dispensing of the powder into the nostrils. [0004] figure 1 Such nostrils are shown schematically. The nostrils have the ostium 1 (sometimes called the nose), the nasal valve 2, the inferior turbinate 3, the middle turbinate 4, the superior turbinate 5, the sinuses 6, the ethmoid sinuses 7, the sphenoid sinuses 8, the sella 9, the posterior nasal pore 10, and the nasopharynx Eustachian tube 11, palat...
