HEADACHE RELIEF EARPLUG
The present invention is directed to an earplug including a body having a first end, a second end and a longitudinal axis extending from the first end to the second end, a bore defined within the body and extending from the first end to the second end along the longitudinal axis of the body, and a pressure regulator positioned within the bore and providing an air flow rate of 3.4×10 −6 to 7.8×10 −5 cc/sec through the bore.
1 . An earplug, comprising:
a body having a first end, a second end and a longitudinal axis extending from the first end to the second end;
a bore defined within the body and extending from the first end to the second end along the longitudinal axis of the body; and
a pressure regulator positioned within the bore and providing an air flow rate of 3.4×10 −6 to 7.8×10 −5 cc/sec through the bore.
2 . The earplug according to claim 1 , wherein the earplug is configured to form an airtight seal with an ear canal when the earplug is inserted into the ear canal.
3 . The earplug according to claim 1 , wherein the body is consists primarily of an airtight material.
4 . The earplug according to claim 1 , wherein the pressure regulator is comprised of a porous material.
5 . The earplug according to claim 4 , wherein the porous material has a porosity of 1.3 to 2 microns.
6 . The earplug according to claim 4 , wherein the porous material is a porous ceramic material.
7 . The earplug according to claim 2 , wherein the body comprises a ribbed neck section comprising at least one rib positioned substantially concentrically around the longitudinal axis of the body, and configured to retain the earplug in the ear canal and prevent any air leakage between the earplug and the ear canal.
8 . The earplug according to claim 1 , wherein the body is comprised of a material having a durometer of between about 60 to 64 on the OO scale.
9 . The earplug according to claim 1 , wherein the body is comprised of silicone.
10 . The earplug according to claim 1 , wherein the pressure regulator is positioned within the bore so as to have an airtight seal between the pressure regulator and the body of the earplug.
11 . A method of treating a headache, comprising:
inserting an earplug into an ear canal, and
leaving the earplug in the ear canal for a period of between about 3 to 24 hours,
wherein the earplug comprises:
a body having a first end, a second end and a longitudinal axis extending from the first end to the second end;
a bore defined within the body and extending from the first end to the second end along the longitudinal axis of the body; and
a pressure regulator positioned within the bore and providing an air flow rate of 3.4×10 −6 to 7.8×10 −5 cc/sec through the bore.
12 . The method according to claim 11 , wherein treating the barometric pressure headache comprises reducing the duration or severity of pain associated with the barometric pressure headache.
13 . The method according to claim 11 , wherein the earplug is configured to form an airtight seal with an ear canal when the earplug is inserted into the ear canal.
14 . The method according to claim 11 , wherein the headache is a barometric pressure headache.
15 . The method according to claim 11 , wherein the ear canal is connected to at least one sinus, and the earplug is configured to facilitate the equilibration of pressure within the at least one sinus and pressure external to the ear canal during the duration the earplug is left in the ear canal.
16 . The method according to claim 11 , wherein the body of the earplug is comprised of a material having a durometer of between about 60 to 64 on the OO scale.
17 . The method according to claim 11 , wherein the body of the earplug comprises a ribbed neck section comprising at least one rib positioned substantially concentrically around the longitudinal axis of the body, and configured to retain the earplug in the ear canal and prevent any air leakage between the earplug and the ear canal.
18 . The method according to claim 11 , wherein the pressure regulator of the earplug is comprised of a porous material.
19 . The method according to claim 18 , wherein the porous material has a porosity of 1.3 to 2 microns.
20 . The method according to claim 18 , wherein the porous material is a porous ceramic material.
