## Abstract

A mask assembly is provided for delivering gas to a patient that includes a mask body and a breathing circuit interface. The mask body includes an opening for reception of the gas and includes a seal structure 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 rotatably connected with the mask body and a second portion that is constructed and arranged to releasably connect with a conduit for delivering the gas to the patient through the opening.

## Claims

### Claim 1

A mask assembly configured to provide gas to a patient, comprising:
a mask body having an opening for reception of the gas, the mask body including a seal structure configured to sealingly engage with the face of the patient and surround at least the nose and mouth of the patient, the mask body having a connecting portion; and
an elbow-shaped conduit releasably connected with the connecting portion of the mask body and being configured to deliver 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 a circuit 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, the conduit being separate and distinct from the mask body and configured to be separate and distinct from the circuit tubing.
