Hybrid ventilation mask with nasal interface and method for configuring such a mask

摘要

A nasal ventilation interface and method for providing nasal ventilation to a patient includes a hybrid face mask, covering only the mouth, coupled with removable nasal inserts extending from the upper surface of the mask. The nasal interface has modular, removable, and disposable nasal pillows connecting the upper surface of the mouth-portion of the mask to the user's nares. Each part of the hybrid mask is modular and can be formed in various shapes and sizes. The ventilation interface has differing gas line entry ports and can be shallow with a relatively deep soft facial interface or deep with a relatively shallow facial interface. In either case, the upper surface receives the nasal interface. The upper surface can have a removable ceiling in which is defined a nasal interface connector. The nasal interface can be integral with a removable ceiling. The entire hybrid mask can be made in one piece.

主权项

1. A respiration assist mask comprising:
a ventilation interface defining a gas entry port to be connected to a positive gas pressure source supplying a gas to said ventilation interface; a cushioned facial interface comprising a non-face contacting periphery comprised of a bottom wall, two side walls, and a top wall, a face contacting periphery extending from the non-face contacting periphery, wherein the top wall has an upper surface that has at least one orifice defined on said upper surface of the non-face contacting periphery; and a nasal interface coupled with said at least one orifice, the nasal interface having a nasal interface gas exit that is external to the cushioned facial interface; wherein the cushioned facial interface is in fluid communication with the ventilation interface and the nasal interface.
