A plug for insertion into a nose or ear of a subject, comprising:
- a body adapted to fit into a nostril or ear canal of the subject, the body comprising a first end arranged to face inward and a second end arranged to face outward during use, wherein the body comprises a compressible, resilient foam material adapted to absorb liquid;
- a hollow tubular member disposed inside the body and extending substantially an entire length of the body and comprising a tubular portion having a first opening facing inwardly and a second opening facing outward during use, the hollow tubular member being arranged to provide fluid communication between the first and second openings;
- wherein the hollow tubular member further comprises a cup-shaped collar arranged on an external surface of the tubular portion and extending radially outward from the tubular portion, wherein a rim of the collar, defined by a radially outermost surface of the collar, is disposed inside the body in contact with an inner wall of the body at the second end of the body, wherein a substantially concave side of the collar faces towards the first end of the body;
- and
- wherein the second opening of the hollow tubular member is adapted to receive a tip of a syringe for injection of a fluid therapeutic agent through the hollow tubular member.
A kit comprising at least one plug for insertion into the nose or ear of a subject and at least one syringe pre-filled with a fluid to be injected into the nostril or ear canal of the subject through the plug, the plug comprising:
- a body adapted to fit into a nostril or ear canal of the subject, the body comprising a first end arranged to face inward and a second end arranged to face outward during use, wherein the body comprises a compressible, resilient foam material adapted to absorb liquid;
- a hollow tubular member disposed inside the body and extending substantially an entire length of the body and comprising a tubular portion having a first opening facing inwardly and a second opening facing outward during use, the hollow tubular member being arranged to provide fluid communication between the first and second openings;
- wherein the hollow tubular member further comprises a cup-shaped collar arranged on an external surface of the tubular portion and extending radially outward from the tubular portion, wherein a rim of the collar, defined by a radially outermost surface of the collar, is disposed inside the body in contact with an inner wall of the body at the second end of the body, wherein a substantially concave side of the collar faces towards the first end of the body;
- and
- wherein the second opening of the hollow tubular member is adapted to receive a tip of the syringe for injection of a fluid therapeutic agent through the hollow tubular member.
