The invention relates to a mask for administering oxygen or other breathable gas to the nose and mouth of a patient. The invention relates to improvements in gas delivery masks, and specifically an improved diffuser structure which is particularly suitable for use in an open mask system, in which the mask body includes substantial openings that allow the user to freely converse, drink, and perform other functions. The improvements also relate to a rebound chamber within the diffuser body spaced apart from the gas conduit outlet, the rebound surface being configured to rebound and reverse the direction of flow of at least a substantial portion of the gas stream exiting the outlet from the forward direction to a rearward direction towards the user's face.

Gas administration mask with dual port diffuser and with gas rebound diffuser

We disclose a mask for administering a breathable gas to a patient, which comprises a mask body and a gas flow disrupter joined to the mask body for generating a turbulent gas plume rearwardly towards the nose and mouth of the patient. The mask body is configured to position the flow disrupter so as to be spaced from and opposing the patient's nose and mouth region when the mask is worn by the patient. The mask includes a gas inlet for admitting gas from an external source into the mask interior, through the gas flow disrupter. The gas flow disrupter can be configured to generate a turbulent gas plume wherein the velocity of gas exiting the disrupter is approximately the same as the gas velocity entering the mask from the gas inlet.
