Problems solved by technology
[0004] Due to its high flexibility, the EMG collection instrument is widely used in large scientific research stages. In order to improve the collection accuracy, the electrode end must always be close to the skin and cannot fall off during muscle movement. In addition, the electrode wire is often caught during use. In case of damage to the mainframe, it is easy to cause huge losses because the mainframe is expensive

The invention belongs to the technical field of myoelectricity collection, and particularly relates to a human body surface multi-degree-of-freedom myoelectricity collector which comprises a host fixing mechanism, an electrode fixing mechanism, a host, a positive and negative electrode mechanism, a mounting plate, a mounting block and an auxiliary electrode. When the myoelectricity collector is in use, the auxiliary electrode installed on the host and an electrode slice in the positive and negative electrode mechanism are guaranteed to be tightly attached to the skin all the time, meanwhile, other positions, except a second suction cup mechanism, of the arc-shaped fixing mechanism are all away from the skin, the second suction cup mechanism, the auxiliary electrode and the positive and negative electrode mechanism are located on the two opposite sides of the limb, that is, the second suction cup mechanism is always away from the auxiliary electrode and the positive and negative electrode mechanism in the working process. According to the design, in the collection process, the collection signals of the positive and negative electrode mechanism and the auxiliary electrode are not affected by the contact between the host fixing mechanism and the electrode fixing mechanism and the skin when the host and the positive and negative electrode mechanism are fixed.
Description
[0001] Technical field [0002] The invention belongs to the technical field of myoelectricity collection, and in particular relates to a human body surface multi-degree-of-freedom myoelectricity collector. Background technique [0003] EMG signal is the temporal and spatial superposition of motor unit action potentials in numerous muscle fibers. Surface electromyographic signal SEMG is the comprehensive effect of superficial muscle EMG and electrical activity of nerve trunk on the skin surface, which can reflect neuromuscular activity to a certain extent; compared with needle electrode EMG, SEMG is non-invasive and non-invasive in measurement. Trauma, simple operation and other advantages. Therefore, SEMG has important practical value in clinical medicine, ergonomics, rehabilitation medicine and sports science. [0004] Because of its high flexibility, the EMG collection instrument is widely used in large scientific research stages. In order to improve the collection accura...
