Abstract

Nasal plug for treatment of nosebleed in a subject, comprising: a body adapted to fit into a nostril of the subject, the body comprising a first end arranged to face inward and a second end arranged to face outward during use; a hollow tubular member disposed inside the body and comprising a first opening facing inwardly and a second opening facing outwardly during use; wherein the tubular member further comprises a collar, adapted to prevent blood of a subject from escaping the body of the nasal plug, and wherein the collar is disposed completely inside the body.

Claims (15)

1. Nasal plug for treatment of nosebleed in a subject, comprising:

a body adapted to fit into a nostril of the subject, the body comprising a first end arranged to face inward and a second end arranged to face outward during use; and

a hollow tubular member disposed inside the body of the nasal plug and comprising a tubular portion having a first opening facing inwardly and a second opening facing outwardly during use;

wherein the hollow tubular member further comprises a collar extending radially outward from the tubular portion and adapted to prevent blood of a subject from escaping the body of the nasal plug,

wherein the body of the nasal plug defines a recess adapted to receive the collar and at least a portion of the tubular portion, and

wherein the collar is disposed inside the recess defined by the body of the nasal plug such that a rim of the collar defined by a radially outermost surface of the collar contacts an inner wall of the body defining the recess.

2. The nasal plug according to claim 1 , wherein the collar of the hollow tubular member is cupped, with a concave side facing the first end of the body and a convex side facing the second end of the body.

3. The nasal plug according to claim 1 , wherein the hollow tubular member protrudes from the second end of the body.

4. The nasal plug according to claim 1 , wherein a first end of the hollow tubular member is disposed proximally of the first end of the body.

5. The nasal plug according to claim 1 , wherein the body of the nasal plug is coated with a substance to be inhaled by the subject.

6. The nasal plug according to claim 1 , wherein the body is made from a resilient foam material.

7. The nasal plug according to claim 6 , wherein the width of the collar in the widest transverse extension of the collar is substantially equal to or greater than the width of the body such that the collar when disposed in the body will stretch and push the body outwardly.

8. The nasal plug according to claim 1 , wherein the hollow tubular member is made from a flexible thermoplastic material.

9. The nasal plug according to claim 1 , wherein a cross-section of the body and/or collar has an oval shape.
