This device, a head-mounted oxygen congestion device, is used to treat hypoxia resulting from various pathological conditions and can be used from infancy to adulthood. It functions by storing oxygen delivered through a tube in a head-mounted helmet, allowing the patient to breathe in high-concentration oxygen. It consists of three main parts: The first part is a transparent, non-rigid plastic head-mounted helmet, thicker on the front than on the sides and top, with a rigid plastic bottom edge. The second part is a neck ring made of natural rubber, with numbered strips on top for cutting to fit the patient's neck, and a bottom connector for a neck ring. The third part is a rigid plastic neck ring with openings for oxygen inlet and outlet, a central opening for connecting auxiliary equipment, and a one-way valve on the upper right for airflow if the helmet collapses. When all three parts are assembled, the device is ready for use. -------------------- (Revised Invention Summary 3/08/59) The headpiece is made of transparent, non-rigid plastic. The front is rectangular, thicker than the other sides, and has a rigid, molded plastic bottom edge. Part 2 is a neck ring made of molded plastic with holes for oxygen inlet and outlet, and a central slot for attaching accessories. The upper right side has a one-way valve for airflow if the headpiece collapses. An inner ring connects to a custom-fit rubber neck band. Once the two parts are assembled, the headpiece is ready for use. ----------------------------------------------------------------------- The headpiece has a rectangular front panel 31 cm wide and 22.5 cm high, with rounded corners, providing a wide 124-degree field of view for a comfortable and uncluttered feel. This also allows for increased airflow in case of negative pressure buildup causing the headpiece to collapse. The neck ring features a one-way valve, 31 mm wide and 0.5 mm thick, made from soft rubber. It is fitted at the top with eight 4 mm air inlet holes on the bottom, and the valve is locked in place. With a neck loop secured by an arrow-shaped locking mechanism located in the center bottom, this design allows air to flow in. In case of negative pressure build-up, causing the front plate of the helmet to collapse against the face, air will continue to flow in, allowing the user to breathe.
