The pelvic floor magnetic stimulator utilizes the principle of electromagnetic induction, where energy storage capacitors rapidly discharge electricity to the stimulation coil. The magnetic field generated by the current in the stimulation coil induces biological current within the biological tissue at the stimulation site, enabling non-invasive and painless stimulation of peripheral nerves. This stimulates neuronal excitatory activity, producing a series of biological effects, which forms the basis of magnetic field stimulation as a diagnostic and therapeutic research instrument. This product is capable of stimulating peripheral nerves, serving as a novel diagnostic device and also a widely used therapeutic research device.

The full-chest multi-frequency oscillatory sputum evacuation device sends pulse signals through the main unit, causing the inflatable air sac to inflate repeatedly and generate high-frequency oscillations, forming directional spontaneous drainage. This promotes the relaxation, liquefaction, and shedding of secretions in the deep parts of the respiratory tract and lung lobes, allowing the sputum to move from the bronchi to the main trachea and then be expelled from the body through coughing or artificial suction.
