Description

technical field [0001] The invention relates to the field of precision instrument detection, in particular to a portable detection device and method based on a neuromuscular electrical stimulator. Background technique [0002] In medicine, neuromuscular electrical stimulators are commonly used to send out electrical pulse sequences to induce muscle movement, stimulate specific muscle groups to make them twitch or contract, and then achieve the technology of "functional" restoration. The size of the electric pulse output by the instrument is directly related to the effect of the treatment, and the stability of its electrical parameter output plays a vital role in the progress of the treatment. At present, the traditional electronic detection instruments have inaccurate readings, insufficient sensitivity and line The type error is relatively large, so it cannot be well applied to the electrical testing of precision instruments. Therefore, it is necessary to design a portable ...
