A patient interface device (8) includes a patient sealing assembly (12) structured to engage a face of the patient when the patient interface device is donned by a patient. The patient sealing assembly has a bottom region (36), a top region (38) opposite the bottom region, and a side region (40, 42) extending from the bottom region to the top region, wherein one or more orifices (48a, 48b) are provided in the side region, the one or more orifices each extending from an interior of the patient sealing assembly to an exterior of the patient sealing assembly and being structured to allow a liquid that condenses within the patient sealing assembly to drain from the patient sealing assembly. |

1. A patient interface device, comprising:
a patient sealing assembly structured to engage a face of the patient when the patient interface device is donned by a patient, the patient sealing assembly having a bottom region, a top region opposite the bottom region, and a side region extending from the bottom region to the top region, wherein one or more orifices are provided in the side region, the one or more orifices each extending from an interior of the patient sealing assembly to an exterior of the patient sealing assembly and being structured to allow a liquid that condenses within the patient sealing assembly to drain from the patient sealing assembly; wherein the patient sealing assembly has a generally triangular shape, wherein the top region comprises an apex region of the patient sealing assembly, wherein the one or more orifices are provided in a predefined region of the side region extending along a length of the side region from a first point of the side region to a second point of the side region, wherein a bisecting line bisects the patient sealing assembly in a direction extending from a middle of the bottom region through a middle of the apex region, wherein a first patient position line is normal to the bisecting line 52, a second patient position line is offset from the first patient position line 54 in a first direction by a first angle having a value from 15 to 45 degrees, and a third patient position line is offset from the first patient position line in a second, opposite direction by a second angle having a value from 0 to 20 degrees, wherein the first patient position line, the second patient position line, and the third patient position line interest the bisecting line at a common point, wherein the first point of the side region is defined by a first location at which a first plane that is normal to the second patient position line is tangent to the patient sealing assembly, and wherein the second point of the side region is defined by a second location at which a second plant that is normal to the third patient position line is tangent to the patient sealing assembly. |
