Device for improving respiration

1. A device for improving respiration, comprising:

at least one nasal insert configured to be inserted into a nostril of a user,

wherein the at least one nasal insert comprises:

a conical base body;

a through-hole extending along a main axis of the base body; and

a spiral element arranged inside the base body and extending from a base of the base body to a tip of the base body;

wherein the spiral element comprises lamellar structures arranged on the spiral element and configured so as to form reservoirs for substances for inhalation.

2. The device of claim 1 , wherein the spiral element has a pitch of 0.1 to 5 mm and/or wherein the spiral element has a number of turns of 1 to 20.

3. The device of claim 1 , wherein the base body comprises one or more struts on which the spiral element is arranged.

4. The device of claim 1 , wherein the lamellar structures extend along a helical line from the base to the tip of the base body.

5. The device of claim 1 , wherein the lamellar structures have a height and/or thickness and/or a distance between each other of between 0.1 and 4 mm.

6. The device of claim 1 , wherein the at least one nasal insert comprises a first nasal insert and a second nasal insert.

7. The device of claim 6 ,

wherein a first magnet is arranged on and/or in an outer side of the base body in the first nasal insert, wherein the first magnet is configured to face the nasal septum when the device is used,

wherein a second magnet is arranged on and/or in an outer side of the base body in the second nasal insert, wherein the second magnet is configured to face the nasal septum when the device is used, and

wherein poles of the first magnet and the second magnet are arranged such that an attracting force exists between the first magnet and the second magnet when the device is used.

8. The device of claim 6 , further comprising a connecting element which connects the first nasal insert and the second nasal insert to each other at the base of their respective base bodies.

9. The device of claim 1 , wherein the base body of the at least one nasal insert has a height of 10 to 50 mm and/or wherein a wall of the at least one nasal insert has a thickness of 0.1 to 4 mm.

10. The device of claim 1 , wherein a diameter of the base body of the at least one nasal insert at its base is 0.2 to 25 mm and/or the diameter of the base body of the at least one nasal insert at its tip is 0.2 to 20 mm.

11. The device of claim 1 , wherein the base body includes a thermoplastic material, in particular a natural rubber-based one.

12. A method for improving respiration, the method comprising inserting the nasal insert of the device of claim 1 into the nostril of a user.
