POSITIVE PRESSURE VENTILATION APPARATUS AND POSITIVE PRESSURE MASK

摘要

A positive pressure ventilation apparatus is provided for non-invasive ventilation of a patient requiring ventilatory care which comprises a positive pressure mask, a positive-pressure source coupled to the positive pressure mask, and an exhalation filter positioned on a gas flow path interconnecting the positive-pressure source and positive pressure mask. The positive pressure mask comprises a mask body configured to cover a patient's mouth and nostrils, the mask body having a patient-contact perimeter, the mask body comprising a flexible concertinaed portion at or adjacent to the patient-contact perimeter to accommodate movement of the patient's face during use, a gas inlet to the mask body configured to be connected to the positive-pressure source, and an adhesive seal positioned at the patient-contact perimeter to secure the mask body to the patient's face and prevent gas leakage during flexion of the concertinaed portion.
