[0002] The hyperbaric oxygen chamber is a special medical device for hyperbaric oxygen therapy. According to the different pressurized media, it is divided into two types: air pressurized chamber and pure oxygen pressurized chamber. Some hyperbaric oxygen chambers use a joystick device to adjust parameters such as the oxygen pressure of the oxygen chamber. Various joystick devices are proposed in the prior art. For example, an industrial joystick device is proposed in the Chinese invention patent application with publication number CN115512982A. The joystick device includes a base, a first cavity and a second cavity are provided in the base, a gear seat is fixed in the first cavity, a gear is installed in the gear seat through a horizontal rotating shaft, and a first magnet is fixed at one end of the horizontal rotating shaft; a first handle is swingably connected to the top of the first cavity, and the lower end of the first handle extends into the first cavity and is fixed with a fan-shaped rack, and the fan-shaped rack is meshed with the gear; a first Hall sensor and a control circuit board are fixed in the second cavity, and the first Hall sensor is electrically connected to the control circuit board and is arranged close to the first magnet; the above-mentioned joystick device overcomes the occurrence of short circuit or corrosion failure of the electrical components caused by water vapor entering the cavity through the action gap of the handle, and ensures the normal operation of the industrial joystick.

When the detection module 24 is placed in the card slot 25, the detection module 24 triggers the conversion switch of the contact end 26, so that the operation mode of the control box 1 is automatically converted to the manual mode;

[0040] The user puts his wrist into the wristband 23, and the detection module 24 contacts the user's wrist, thereby detecting the user's blood oxygen concentration. The user's wrist drives the wristband 23 and the detection module 24 to be taken out of the card slot 25, avoiding restraining the user's wrist and allowing the user to perform other activities. When the detection module 24 is taken out of the card slot 25 or the detection module 24 is put into the card slot 25, the detection module 24 triggers the conversion switch of the contact end 26, so that the operation mode of the control box 1 is automatically converted, that is, the manual mode is turned on when the detection module 24 is connected to the contact end 26, and the automatic mode is turned on when the detection module 24 is disconnected from the contact end 26. The controllers of the multiple photoelectric receiving panels 9 in the control box 1 automatically adjust the parameters of the oxygen chamber according to the user's blood oxygen concentration. Of course, the manual mode has a higher priority than the automatic mode.

[0041] When the controllers of multiple photoelectric receiving panels 9 receive the automatic parameter adjustment command input by the voice module 22 or the detection module 24, the controller controls the corresponding electromagnetic coil 28 to generate magnetic force, so that the corresponding electromagnetic coil 28 attracts the magnet 27, thereby driving the handle 2 to rotate around the main axis 3, so that the magnet 27 is adsorbed and aligned with the corresponding electromagnetic coil 28, so that the handle 2 automatically swings to the angle corresponding to the numerical end of the automatic parameter adjustment, avoiding misoperation when switching to manual mode and improving practicality.

When the detection module 24 is taken out of the card slot 25, the detection module 24 triggers the conversion switch of the contact end 26, so that the operation mode of the control box 1 is converted into the automatic mode. The controllers of the multiple photoelectric receiving boards 9 in the control box 1 automatically adjust the parameters of the oxygen chamber according to the user's blood oxygen concentration, or perform voice operations through the voice module 22. Finally, when the controllers of the multiple photoelectric receiving boards 9 receive the automatic parameter adjustment instructions input by the voice module 22 or the detection module 24, the controller controls the corresponding electromagnetic coil 28 to generate magnetic force, so that the corresponding electromagnetic coil 28 absorbs the magnet 27, thereby driving the handle 2 to rotate around the main axis 3, so that the magnet 27 is adsorbed and aligned with the corresponding electromagnetic coil 28, so that the handle 2 automatically swings to the angle of the numerical end corresponding to the automatic parameter adjustment, thereby avoiding misoperation when switching to manual mode.

[0044] 1. Two-level adjustment can be performed through the handle and the wheel, with fast adjustment speed and high adjustment accuracy, which can shorten the swing stroke of the handle and make the operation more convenient;

[0045] 2. The handwheel adjustment has a self-locking function, making the operation more stable;

[0046] 3. Capable of voice control;

[0047] 4. It can be automatically controlled by detecting blood oxygen concentration;

[0048] 5. Avoid misoperation when switching to manual mode by adaptively adjusting the angle of handle 2.
