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.
Claims17
A mask assembly for providing a flow gas to a patient, comprising:
- (a) a mask body having an opening for receiving the flow of gas, the mask body including a seal structure for sealingly engaging with a face of such a patient and surrounding at least a nose and mouth of such a patient, the mask body having a connecting portion;
- and
- (b) a conduit releasably connected with the connecting portion of the mask body for delivering the flow of as to such a patient through the opening, the conduit comprising:
- (1) a first connector portion having an outer surface contacting an inner surface of the connecting portion, and
- (2) a second, connector portion fbr connecting with a tubing adapted to carry the flow of gas to the mask assembly, wherein the first connector portion comprises a plurality of grooves circumferentially spaced on the outer surface of the first connector portion, the grooves extending beneath the connecting portion and outwardly from a distal end of the connecting portion to thereby provide a path for allowing gas to escape from the mask body through the connecting portion and the grooves.
A mask assembly kit for providing a flow of gas to a patient, comprising:
- a mask body having an opening for receiving the flow of gas, the mask body including a seal structure for sealingly engaging with a face of such a patient and surrounding at least a nose and mouth of such a patient;
- a first, valveless conduit;
- a second conduit containing a valve, each of the first and the second conduits comprising a first connector portion having an outer surface structured to contact an inner surface of a connecting portion associated with the mask body, and a second connector portion for connecting with a tubing adapted to carry the flow of gas to the mask assembly, wherein connecting portion of the mask body is selectively attachable to the first connector portion of either the first conduit or the second conduit, wherein the first connector portion of the second conduit comprises a plurality of grooves circumferentially spaced on the outer surface of the first connector portion, the grooves being structured to extend beneath the connecting portion and outwardly from a distal end of the connecting portion to thereby provide a path for allowing gas to escape from the mask body through the connecting portion and the grooves when the second conduit is coupled to the mask body.
