It can also improve hypoxia in high-altitude environments. Hyperbaric oxygen chambers are gradually entering homes, professional oxygen bars, medical aesthetic clinics, health and wellness communities, and high-altitude hotels. A search revealed Chinese patent CN116421430A, which discloses a vehicle-mounted high-altitude pressurized chamber and its usage method. The chamber includes a transport vehicle with a support plate. The key feature is that support blocks are located at both ends of the upper surface of the support plate, and shock absorbers are installed between the ends of the support blocks and the support plate. A chamber body is fixedly connected between two support blocks. Several drive plates are slidably connected to one support block of the support plate. A door is fixedly connected to the end of the drive plate away from the transport vehicle. The upper end of the door is equipped with an electric lock for fixing to the chamber body, and a seating component for the user to sit on is provided on the door. A drive component for moving the drive plates is also provided between the two support blocks. Several lighting windows are provided on one side of the upper end of the chamber body, and a temperature regulating component is provided inside the chamber body for adjusting the internal temperature. The vehicle interior is also equipped with an oxygen filling assembly for filling the cabin with oxygen. The seating assembly includes a floor slide plate, which is fixedly connected to the lower end of the cabin door near the cabin body. Several seats are provided on the floor slide plate. Floor casters are installed on the floor slide plate inside the cabin body. The drive assembly includes sliding rods, which are fixedly connected to both ends of a support block. A threaded rod is rotatably connected to the middle of the support block. A drive motor for driving the threaded rod to rotate is provided on the support block at one end of the cabin body.
