Abstract

A mask system for delivery of respiratory therapy to a patient includes a nares portion and a mouth portion and an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver the pressurized, breathable gas. The mask system is adapted to selectively utilize the nares portion and/or the mouth portion in a first mode utilizing both the nares portion and the mouth portion, and in a second mode utilizing the nares portion and not utilizing the mouth portion.

First claim

What is claimed is:

1. A mask system for delivery of respiratory therapy to a patient, comprising:
a nares portion adapted to form a seal with a patient's nares;
a mouth portion including a mouth chamber and a mouth sealing portion adapted to form a seal with a patient's mouth, the mouth chamber including an opening adapted to selectively receive pressurized, breathable gas; and
an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver the pressurized, breathable gas,
wherein the mouth portion is selectively removable from the mask system to selectively arrange the mask system between: (1) a first configuration utilizing both the nares portion and the mouth portion to form the seal with both the patient's nares and the patient's mouth and deliver the pressurized, breathable gas to the patient's nares and/or the patient's mouth; (2) a second configuration utilizing only the nares portion to only form the seal with the patient's nares and only deliver the pressurized, breathable gas to the patient's nares; and (3) a third configuration utilizing only the mouth portion to only form the seal with the patient's mouth and only deliver the pressurized, breathable gas to the patient's mouth, and
wherein said opening of the mouth portion is a first opening and the mouth portion further comprises a second opening that is separate and distinct from the first opening, and the first opening is structured and arranged to allow selective attachment to the nares portion and the second opening is structured and arranged to allow selective attachment to the inlet conduit.

2. The mask system according to claim 1 , further comprising a plug adapted to plug the first or second opening in the mouth chamber in the first configuration so that the mouth chamber is utilized as a mouth seal that does not deliver any of the pressurized, breathable gas to the patient's mouth.

3. The mask system according to claim 1 , wherein the inlet conduit is connectable to the nares portion to deliver the pressurized, breathable gas to the nares of the patient.

4. The mask system according to claim 1 , wherein when in use in the first configuration, the second opening in the mouth chamber is connectable to the inlet conduit to deliver the pressurized, breathable gas to the patient's mouth.

5. The mask system according to claim 4 , further comprising a connector adapted to connect the nares portion to the mouth chamber of the mouth portion, wherein the connector is adapted to communicate a portion of the pressurized, breathable gas between the mouth chamber and the nares portion.

6. The mask system according to claim 1 , further comprising a double elbow connector adapted to connect the inlet conduit to both the nares portion and the mouth portion for use of the mask system in the first configuration.

7. The mask system according to claim 3 , further comprising a swivel ring in the nares portion or in the second opening in the mouth chamber adapted to connect to the inlet conduit.

8. The mask system according to claim 1 , wherein the mouth sealing portion includes a silicone cushion.

9. The mask system according to claim 1 , wherein at least one of the nares portion and the mouth portion includes headgear connectors adapted to connect to headgear.

10. The mask system according to claim 1 , wherein both of the nares portion and the mouth portion include headgear connectors adapted to connect to headgear.

11. The mask system according to claim 9 , wherein the headgear includes upper side straps adapted to be routed between the patient's eyes and ears and lower side straps routed under the patient's ears.

12. The mask system according to claim 11 , wherein the headgear includes a crown strap portion adapted to be positioned in use over the crown of the patient's head.

13. The mask system according to claim 12 , wherein the headgear includes a rear strap portion connected to the upper side straps above the patient's ears and adapted to angle downward along the sides of the patient's head in use to capture the occiput of the patient's head.

14. The mask system according to claim 13 , wherein the rear strap portion is connected to the lower side strap below the occiput of the patient's head.

15. The mask system according to claim 1 , wherein the nares portion includes a nares sealing portion adapted to form the seal with the patient's nares in use.

16. The mask system according to claim 15 , wherein the nares sealing portion comprises one of pillows, prongs, a membrane seal, or a nasal chamber.

17. The mask system according to claim 16 , wherein the nares sealing portion is structured to extend or curve outwardly from a supporting wall defining an air path into the nares sealing portion.

18. The mask system according to claim 17 , further comprising a plurality of rigid elements disposed on a lower side of the nares sealing portion, and a dial connected to the rigid elements, the dial when turned adapted to cause the rigid elements to move upwards or downwards to adjust a pinching force of the nares sealing portion.

19. The mask system according to claim 1 , wherein the mouth sealing portion includes a foam patient contacting portion.

20. The mask system according to claim 8 , wherein the silicone cushion is formed in a substantially u-shape, and the nares portion includes a nares sealing portion adapted to form the seal with the patient's nares in use, the nares sealing portion being connected to two side portions of the silicone cushion.

21. The mask system according to claim 20 , wherein the nares sealing portion includes a stretching element adapted to allow the patient to selectively stretch the nares sealing portion.

22. The mask system according to claim 1 , further comprising a vent formed in at least one of the nares portion and the mouth portion, the vent adapted to vent gas exhaled by the patient.

23. The mask system according to claim 22 , wherein the vent comprises a plurality of vent holes.

24. The mask system according to claim 15 , wherein the inlet conduit is connected to the nares portion, and the nares portion includes a nares decoupling portion adapted to decouple forces applied to the inlet conduit from the nares sealing portion.

25. The mask system according to claim 1 , wherein the inlet conduit is connected to the mouth portion, and the mouth portion includes a mouth decoupling portion adapted to decouple forces applied to the inlet conduit from the mouth sealing portion.

26. A mask system for delivery of respiratory therapy to a patient, comprising:
a nares portion adapted to form a seal with a patient's nares;
a mouth portion including a mouth chamber and a mouth sealing portion adapted to form a seal with a patient's mouth; and
an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver pressurized, breathable gas to the patient,
wherein the nares portion and the mouth portion are adapted to selectively attach to each other and detach from each other,
wherein the mouth portion is adapted to selectively function in both a first configuration where at least a portion of the pressurized, breathable gas is delivered to the patient's mouth and in a second configuration where the mouth portion functions as a mouth seal that prevents any of the pressurized, breathable gas from being delivered to the patient's mouth,
wherein the mouth portion is adapted t
