Patients with diseases of the heart and lungs, such as pulmonary hypertension, may not comply with use of a face mask or nasal cannula for delivery of medical gas. Movement can also render medical gas delivery methods ineffective if a patient turns their head away from the gas source.

The proposed medical gas delivery device could be incorporated with a hat, hood, pillow or other garment to provide supplemental oxygen and other gases near the face of patients who struggle with a face mask or nasal cannula. The device permits patients to move without interrupting the flow of medical gas. The initial hoody device delivers medical gas from a source near the waist through a tube that expels the medical gas near the patient’s face. This reduces the chance of air-flow disruption, common with long tubing, and improves patient compliance due to the increased comfort of the delivery device.
