Reduced Friction Eartips, And Systems And Methods Therefore
The application discloses an a method of forming a lower friction eartip when compared to a pretreated elastomer eartip.
1 . An eartip comprising:
an outer portion; and
an inner portion, wherein the outer portion is designed to contact the ear canal, and wherein the inner portion is designed to fit upon a stent, where the eartip is formed by curing a combined mixture where the combined mixture is formed by combining 1-15% by weight or volume of lubricant with a remaining amount of elastomer.
2 . The eartip according to claim 1 , wherein the skin friction coefficient of the outer portion is less than 2.
3 . The eartip according to claim 2 , where the lubricant is a hydrophobic medium.
4 . The eartip according to claim 3 , where the hydrophobic medium is at least one of mineral oil, a wax, olive oil, and vegetable oil.
5 . The eartip according to claim 4 , where the combined mixture is formed by combining the hydrophobic medium by weight within the range of 3-8% of the weight of the combined mixture.
6 . The eartip according to claim 4 , where the combined mixture is formed by combining the hydrophobic medium by volume within the range of 3-8% of the volume of the combined mixture.
7 . The eartip according to claim 5 , where a hydrophobic coating is placed upon the outer portion.
8 . The eartip according to claim 6 , where a hydrophobic coating is placed upon the outer portion.
9 . The eartip according to claim 8 , where the hydrophobic coating is placed by dipping the ear tip outer surface into a treatment solution for period of time between 30 minutes to 3 hours.
10 . The eartip according to claim 9 , where the treatment solution is heated between 30 C to 150 C.
11 . The eartip according to claim 5 , where a hydrophobic coating is placed upon the outer portion.
12 . The eartip according to claim 11 , where the hydrophobic coating is placed by dipping the ear tip outer surface into a treatment solution for period of time between 30 minutes to 3 hours.
13 . The eartip according to claim 12 , where the treatment solution is heated between 30 C to 150 C.
14 . A method for forming ear tips, the method comprising:
measuring one of a volume V1 of a lubricate or a weight W1 of a lubricant;
measuring one of a volume V2 of an elastomer epoxy or a weight W2 of an elastomer epoxy, where V1 or W1 is within a percentage range of 3 to 15% of V2 or W2;
mixing the lubricant with the epoxy to form a combined mixture during a work time of a curable epoxy;
insert the combined mixture into a mold used to form an eartip during the work time of the epoxy; and
removing the eartip from the mold after a cure time, where the eartip coefficient of friction is less than 2.0
15 . The method according to claim 14 , where the lubricant is a hydrophobic medium.
16 . The eartip according to claim 15 , where the hydrophobic medium is at least one of mineral oil, a wax, olive oil, and vegetable oil.
17 . The eartip according to claim 16 , where the combined mixture is formed by combining W1 with W2 where W1 is within the range of 3-8% of the total weight of W1+W2.
18 . The eartip according to claim 16 , where the combined mixture is formed by combining V1 with V2 where V1 is within the range of 3-8% of the total weight of V1+V2.
