Abstract

The present invention relates to a mask bead for a patient interface, comprising a nose bridge region, at least one side region, a base region, a mask bead attachment, and a bearing region on the patient. The bearing region extends from the side regions and the base region and also the nose bridge region to an opening and is designed as a sealing lip which frames the central opening which serves at least for the introduction of the nose of the patient. The mask bead is formed from at least one elastic material and comprises at least one support structure in the mask bead, which support structure is designed to in part face the bearing region and to in part face the mask bead attachment.

Claims

1. A mask bead for a patient interface, wherein the bead comprises a nose bridge region, one or more side regions, a base region, a mask bead attachment, and a bearing region on a patient, and wherein the bearing region extends from the side regions and the base region and also the nose bridge region to an opening and is designed as a sealing lip which frames the opening which serves at least for an introduction of a nose of the patient, the mask bead being formed from at least one elastic material and comprising at least one support structure which is designed to in part face the bearing region and to in part face the mask bead attachment.

3. The mask bead of claim 1, wherein the support structure comprises at least two reinforcement points and at least one connecting structure between two reinforcement points.

4. The mask bead of claim 3, wherein the at least one connecting structure is designed as an arch.

5. The mask bead of claim 3, wherein the reinforcement points in the mask bead are arranged in a region of the bearing region or are arranged lying on the bearing region.

6. The mask bead of claim 3, wherein, starting from at least one connecting structure of the support structure, a supporting element is formed which widens in a direction of a mask bead attachment.

7. The mask bead of claim 6, wherein the supporting element is formed running centrally or laterally from the connecting structure.

8. The mask bead of claim 6, wherein at least one kink region is formed at at least one transition of the support structure to the supporting element.

9. The mask bead of claim 8, wherein at least one of the kink regions is formed by a reduction of a thickness of the support structure.

10. The mask bead of claim 8, wherein the support structure and at least one kink region form at least one adjustment region.

11. The mask bead of claim 3, wherein the reinforcement points are formed at a transition of the nose bridge region to a side region and/or at a transition of the base region to a side region.

12. The mask bead of claim 3, wherein the reinforcement points of the support structure are arranged in at least one side region.

13. The mask bead of claim 1, wherein at least one connecting structure is formed over the nose bridge region of the mask bead, and wherein reinforcement points delimiting the connecting structure are arranged at respective side regions of the mask bead separated by the opening.

14. The mask bead of claim 1, wherein at least one connecting structure is formed over a side region of the mask bead, and wherein reinforcement points delimiting the connecting structure are arranged on a common side region of the mask bead.

15. The mask bead of claim 1, wherein the support structure has a wall thickness that is 1/12 to ⅛

thicker than a respective region in which it is formed.

16. The mask bead of claim 1, wherein the support structure has a wall thickness of from 2 mm to 1.8 mm, and a surrounding mask bead wall has a wall thickness of about 1.6 mm.

17. The mask bead of claim 1, wherein the support structure comprises at least two reinforcement points and at least one connecting structure between two reinforcement points, and wherein the at least one connecting structure is designed as an arch which faces away from the bearing region.

18. The mask bead of claim 1, wherein at least one kink region is formed at at least one transition of the support structure to a supporting element, the support structure and the at least one kink region forming at least one adjustment region having a wall thickness of from 0.2 mm and 0.7 mm.

2. The mask bead of claim, wherein the support structure surrounds the opening at least by two thirds or completely.

19. A mask bead, wherein the bead comprises a nose bridge region, one or more side regions, a base region, a mask bead attachment, and a bearing region on a patient, wherein the bearing region extends from the side regions and the base region and also the nose bridge region to an opening and is designed as a sealing lip which frames the opening which serves at least for an introduction of a nose of the patient, the mask bead comprising at least one support structure and at least one kink region which form at least one adjustment region having a wall thickness of from 0.2 mm to 0.7 mm.

20. A mask bead, wherein the bead comprises a nose bridge region, one or more side regions, a base region, a mask bead attachment, and a bearing region on a patient, and wherein the bearing region extends from the side regions and the base region and also the nose bridge region to an opening and is designed as a sealing lip which frames the opening which serves at least for an introduction of a nose of the patient, the mask bead comprising at least one support structure which has a wall thickness of from 2 mm to 1.8 mm, the nose bridge region having a wall thickness of from 0.2 mm to 0.7 mm, the base region having a wall thickness of from 0.5 mm to 1.2 mm and a side region having a wall thickness of from 1.2 mm to 2.5 mm.
