Abstract

A mask assembly (10) is provided for delivering gas to a patient that includes a mask body (12) and a breathing circuit interface (16). The mask body includes an opening (13) for reception of the gas and includes a seal structure (20) for sealingly engaging with the face of the patient and surrounding at least the nose and mouth of the patient. The breathing circuit interface includes a first portion (17) rotatably connected with the mask body and a second portion (19) that is constructed and arranged to releasably connect with a conduit (18) for delivering the gas to the patient through the opening.

Claims

1. A mask assembly for providing gas to a patient, comprising:

a mask body having an opening for reception of the gas, the mask body including a seal structure for sealingly engaging with the face of the patient and surrounding at least the nose and mouth of the patient, the mask body having a connecting portion; and

a conduit releasably connected with the connecting portion of the mask body for delivering the gas to the patient through the opening, the conduit comprising a first connector portion which connects with the connecting portion, and a second connector portion constructed and arranged to connect with tubing, wherein the first connector portion comprises a plurality of recesses at an interface with the connecting portion to allow exhaled gas to escape therethrough.

2. The mask assembly according to claim 1, further comprising a breathing circuit interface connected with the mask body, and wherein the connecting portion is formed on the breathing circuit interface.

3. The mask assembly according to claim 2, wherein the breathing circuit interface is rotatably connected with the mask body.

4. The mask assembly according to claim 3, wherein the conduit is constructed and arranged to form a friction fit connection with the connecting portion.

5. The mask assembly according to claim 1, wherein the conduit is constructed and arranged to form a friction fit connection with the connecting portion.

6. The mask assembly according to claim 1, wherein the conduit comprises an inlet constructed and arranged to connect with tubing, an outlet constructed and arranged to connect with the connecting portion, a secondary inlet between the inlet and the outlet, the secondary inlet communicating the conduit with atmosphere and a valve that is movable between a first position sealing the inlet and a second position sealing the secondary inlet.

7. The mask assembly according to claim 6, wherein the valve comprises a flexible member that normally seals the inlet and is flexible upon application of pressurized gas through the inlet to move to the second position sealing the secondary inlet.

8. A mask assembly kit for providing gas to a patient, comprising:

a mask body having an opening for reception of the gas, the mask body including a seal structure for sealingly engaging with the face of the patient and surrounding at least the nose and mouth of the patient;

a first, valveless conduit; and

a second conduit containing a valve,

each of the conduits comprising a first connector portion which connects with a connecting portion associated with the mask body, and a second connector portion constructed and arranged to connect with tubing, wherein connecting portion of the mask body is constructed and arranged to be selectively attached to the first connector portion of either the first conduit or the second conduit.

9. The mask assembly kit according to claim 8, wherein each first connector portion of the conduits is constructed and arranged to form a friction fit connection with the connecting portion.

10. The mask assembly kit according to claim 9, further comprising a breathing circuit interface connected with the mask body and providing the connecting portion that connects the mask body with the selected conduit.

11. The mask assembly kit according to claim 10, wherein the breathing circuit interface forms a friction fit connected with the selected conduit.

12. The mask assembly kit according to claim 10, wherein the breathing circuit interface forms a rotatable connection with the mask body.

13. The mask assembly kit according to claim 11, wherein the second conduit comprises a plurality of recesses that provide gas communication between the patient and atmosphere at the friction fit connection between the second conduit and the breathing circuit interface.
