A human body surface myoelectric collection device

Abstract

The invention belongs to the technical field of myoelectric collection equipment, and in particular relates to a human body surface myoelectric collection equipment, which includes a first fixing mechanism, a second fixing mechanism, a host, a positive and negative electrode mechanism, and an auxiliary electrode mechanism. During the process, ensure that the electrode sheets in the auxiliary electrode mechanism and the positive and negative electrode mechanisms are always close to the skin, and at the same time, the arc-shaped fixing mechanism is away from the skin except for the first suction cup, and the first suction cup is connected with the auxiliary electrode mechanism and the positive and negative electrodes. The mechanism is located on 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 during the working process. This design can ensure that the first fixing mechanism and the second fixing mechanism Because the contact with the skin when the host, the auxiliary electrode mechanism and the positive and negative electrode mechanisms are fixed will not affect the acquisition signals of the positive and negative electrode mechanisms and the auxiliary electrode mechanisms.

Description

[0001] Technical field [0002] The invention belongs to the technical field of electromyography collection equipment, and in particular relates to an electromyography collection equipment on the surface of a human body. Background technique [0003] EMG acquisition 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 acquisition in the muscle experiment process. The distance between the positive electrode and the negative electrode is 2CM. The wire of the host is 9CM, and the electrical signal is not easily affected by long wires under the flexible arrangement of the host and the electrode. On the other hand, when the electrode collects the signal, the muscle where the electrode is installed cannot be pulled and pressed, otherwise the electrical signal of the muscle will be affected. ; Under the requirement that the current muscle collector cann...

[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
