Ear canal sealing stethoscope ear tips
View Patent ↗An ear tip is adapted to deliver sound to an ear canal. The ear tip includes a first section, a second section and a third section. The first section is connectable to a sound-transmitting device. The second section has a first end, a second end and walls defining a bulbous section. The first end is connected to and in open communication with the first section. The second end is connected to and in open communication with the third section. The third section includes walls defining a flume and an outlet port adapted for open communication with the ear canal. The outlet port has a maximum outer diameter of about 11 millimeters. In a relaxed state, a ratio of a maximum outer diameter of the second section to a maximum diameter of the third section is between about 1.25 and about 2.5.
1. An ear tip adapted to deliver sound to an ear canal, the ear tip comprising:
a first section connectable to a sound-transmitting device;
a second section having a first end, a second end and walls defining a hollow bulbous section, wherein the first end is connected to and in open communication with the first section; and
a third section connected to and in open communication with the second end of the second section, the third section comprising:
walls defining a flume;
an outlet port adapted for open communication with the ear canal, wherein the
outlet port has a maximum outer diameter of about 11 millimeters (mm); and
a flange extending from the outlet port;
wherein in a relaxed state, a ratio of a maximum outer diameter of the second section to a maximum outer diameter of the third section is between about 1.25 and about 2.5.
2. The ear tip of claim 1 , wherein the outlet port of the third section has a minimum outer diameter of about 5 mm.
3. The ear tip of claim 1 , wherein the third section has a length of between about 2.5 to about 6.4 mm.
4. The ear tip of claim 1 , wherein the outlet port of the third section is compressible to an oval shape, wherein a diameter of the oval is up to about 50% larger than the diameter of the outlet port in an uncompressed state.
5. The ear tip of claim 1 , wherein the flange has an outer diameter of between about 8.1 and about 13.2 mm.
6. The ear tip of claim 1 , wherein the flange has a dome height of between about 4 and about 8 mm.
7. The ear tip of claim 1 , wherein the flange has a thickness of between about 0.3 and about 1.0 mm.
8. The ear tip of claim 1 , further comprising a channel passing through the first section, wherein the channel is configured to receive a transmitting tube.
9. The ear tip of claim 1 , wherein the second section comprises a hollow inner chamber.
10. The ear tip of claim 1 , wherein the hollow inner chamber of the second section is positioned between the terminal end of the transmitting tube and the third section.
11. The ear tip of claim 1 , wherein the sound-transmitting device is a stethoscope.
12. An ear tip comprising:
a first section connectable to a sound-transmitting device;
a second section having a first end, a second end and walls defining a hollow bulbous section surrounding an inner chamber, wherein the first end is connected to and in open communication with the first section; and
a third section connected to and in open communication with the second end of the second section, the third section comprising walls defining a flume, wherein the flume includes a tip positionable within a human ear canal and wherein the flume has a length of about 2.5 to about 6.4 millimeters (mm);
wherein the second and third sections are deformable under an axial force in a range of between about 2.22 to about 5.56 Newtons from a relaxed state to a compressed state and the flume tip exhibits a compression diameter increase of up to 50 %.
