Sealing face mask for patients with indwelling nasogastric tubes

Abstract

This invention belongs to the technical field of medical auxiliary devices. In view of the poor performance of sealing face masks currently used for patients with indwelling nasogastric tubes, the invention provides a sealing face mask for patients with indwelling nasogastric tubes. The sealing face mask comprises: a sealing face mask body, a nasogastric tube connecting cylinder, and a sealing mechanism arranged at the outlet of the nasogastric tube connecting cylinder. Through the sealing mechanism, the invention can seal the gap between the inner wall of the nasogastric tube connecting cylinder and the outer wall of the nasogastric tube, thereby preventing oxygen leakage and ensuring the effectiveness of oxygen inhalation for the patient.
