Description

Technical Field

[0001] The utility model belongs to the field of medical equipment, and in particular relates to a pulse magnetic field stimulator with a temperature protection function. Background Art

[0002] The principle of a pulsed magnetic field stimulator is based on the law of electromagnetic induction. By charging a high-voltage energy storage capacitor and discharging it into a stimulation coil in a very short time, the powerful current generates a transient magnetic field around the coil, inducing an induced electric field and current in the human peripheral nerves, achieving painless, non-destructive, and non-invasive inductive stimulation. This magnetic field can pass through the surface of the limb unimpeded and unshielded, controlling the nerves inside the limb to induce an induced electric field and current, thereby stimulating and exciting the nerves within the limb.

[0003] In order to meet the needs of some patients who are inconvenient to travel, a portable home version of the pulsed magnetic field stimulator has appeared. However, the existing home version of the pulsed magnetic field stimulator does not have a special heat dissipation structure inside. Although the heat generated within half an hour of use will not affect the device, in order to ensure the treatment effect, the actual use time often exceeds half an hour. The use time exceeding half an hour will cause the internal overheating of the device, thereby causing damage. In view of this, the present utility model is specially proposed. Utility Model Content

[0015] 1.
