Means and method for fluid pulses
First Claim
1. A pulsating therapeutic inhaler generating pneumatic pulses for treating respiratory disorders, said inhaler comprising:
- a. a linear passage having an elongate axis;
b. a patient interface fluidly connectable to the patient'"'"'s respiratory tract having a curvilinear aperture fluidly connectable to said linear passage;
said curvilinear aperture selected from the group consisting of a circle and a circular trapezoid; and
c. a flat shutter disposed between said linear passage and said aperture configured to modulate a fluid pressure within a fluid flow;
said flat shutter comprising a disc (110) having at least one cutout (120) and rotating about an axis parallel to said elongate axis of said linear passage;
said cutout has four cornered perimeter thereof with two radial side portions (123 and 125) and two circumferential arcs (127 and 129) configured relative to said rotation axis;
said side portions are circumferentially anti-symmetrical relative to said aperture.

Abstract
A pulsating therapeutic inhaler generating pneumatic pulses for treating respiratory disorders. The inhaler includes: a linear passage that has an elongate axis and is configured to conduct a fluid flow in a laminar manner; a patient interface fluidly connectable to the patient'"'"'s respiratory tract having an aperture fluidly connectable to the passage; and a shutter disposed between the passage and the aperture configured to modulate a fluid pressure within the fluid flow. The shutter includes a disc having at least one cutout and rotating about an axis parallel to the passage axis. The cutout has four cornered perimeter thereof with two side portions and two circumferential arcs configured relative to the rotation axis. The side portions are circumferentially anti-symmetrical relative to the aperture.

13. A method of treating respiratory disorders by means of applying pneumatic pulses to the patient'"'"'s respiratory tract;
- said method comprising the steps of;
a. providing a pulsating inhaler further comprising i. a linear passage having an elongate axis; ii. a patient'"'"'s interface fluidly connectable to the patient'"'"'s respiratory tract having an aperture fluidly connectable to said linear passage; and iii. a flat shutter disposed between said linear passage and said aperture configured to modulate a fluid pressure within a fluid flow;
said flat shutter comprising a disc having at least one cutout and rotating about an axis parallel to said elongate axis of said linear passage;b. fluidly connecting said patient interface to the patient'"'"'s respiratory tract; c. modulating said fluid pressure within said fluid flow by means of said flat shutter; wherein said step of modulating said fluid pressure is performed by said cutout having four cornered perimeter thereof with two radial side portions and two circumferential arcs configured relative to said rotation axis;
said side portions are circumferentially anti-symmetrical relative to said aperture. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
