Myoelectricity acquisition equipment for human body surface

Abstract

The invention belongs to the technical field of myoelectricity acquisition equipment, and particularly relates to myoelectricity acquisition equipment for a human body surface. The myoelectricity acquisition equipment comprises a first fixing mechanism, a second fixing mechanism, a host, a positive and negative electrode mechanism and an auxiliary electrode mechanism. In the working process, it is guaranteed that electrode plates in the auxiliary electrode mechanism and the positive and negative electrode mechanism are always attached to the skin, meanwhile, the other positions, except a first suction cup, of the arc-shaped fixing mechanisms are all away from the skin, the first suction cup, the auxiliary electrode mechanism and the positive and negative electrode mechanism are located on the two opposite sides of the limbs, that is, the first suction cup is always away from the auxiliary electrode mechanism and the positive and negative electrode mechanism in the working process, and by the design, it can be guaranteed that in the acquisition process, when the first fixing mechanism and the second fixing mechanism are in contact with the skin due to the fact that the host, the auxiliary electrode mechanism and the positive and negative electrode mechanism are fixed by the first fixing mechanism and the second fixing mechanism, acquisition signals of the positive and negative electrode mechanism and the auxiliary electrode mechanism cannot be affected.

[0003] Myoelectric collection is mostly used in scientific research institutions. It is composed of three electrodes, one positive electrode, one negative electrode and one reference electrode, for the muscle signal collection in the muscle experiment process. The distance between the positive electrode and the negative electrode is 2CM. In addition, the positive and negative electrodes and The wire of the main unit is 9cm, and the electrical signal is not easily affected by the long wire while ensuring the flexible arrangement of the main unit and the electrodes. On the other hand, when the electrodes are collecting signals, the muscles where the electrodes are installed cannot be pulled and pressed, otherwise the electrical signals of the muscles will be affected ;The current muscle collector is not easy to reliably fix the host electrode on the muscle under the requirement that the wire 9cm and the muscle collection site cannot be pulled and pressed. Especially during exercise testing, the host and electrodes are easy to fall off
