A non-horizontal folding mask is provided. A breathable region of a mask body is provided with at least one non-horizontally extended folding portion; and the folding portion is a folding and breathing filtration layer. During use, unfolding the folding portion can increase an area of the breathable region of the mask body to improve the filtering effect, and can accommodate and buffer more exhaled gas to effectively prevent escape of the gas from an upper end of a nose and a chin to further improve the filtering effect. The non-horizontally extended folding portion can support a breathing chamber formed by unfolding the mask body overall, preventing collapse and expansion of the breathing chamber in the breathing process to avoid gas leakage.

The application discloses a novel intelligent lung rehabilitation dynamic monitor, which comprises a monitoring seat, a control panel, a myoelectricity electrode, an arc-shaped gasket and a dynamic adjusting mechanism, wherein the dynamic adjusting mechanism comprises a displacement mechanism, a hollow tube, a spring, a moving rod, a flexible balloon, a magneto-rheological fluid, an electromagnet and a current adjusting mechanism; the arc-shaped gasket can be attached to the chest cavity of a user through the displacement mechanism, so that the myoelectricity electrode can collect lung myoelectricity signals; the expansion and contraction of the chest cavity during the breathing process of the user can drive the moving rod to move, and the current adjusting mechanism is used for adjusting the current size delivered to the electromagnet; the viscosity of the magneto-rheological fluid is adjusted through the change of the magnetic field intensity, and then the rigidity of the flexible balloon is changed; during inhalation, the flexible balloon with larger rigidity can keep the movement of the moving rod stable; the rigidity of the flexible balloon decreases during breathing, and the spring can pull the moving rod to reset, so that the myoelectricity electrode can stably collect myoelectricity signals, thereby being used for evaluating the rehabilitation effect of the lung of the user.
