Problems solved by technology

However, the wet electrode also has the following disadvantages, including: the adhesive sticks the electrode to the skin, which can cause allergic dermatitis; the ion gel (membrane) has toxicity at a certain concentration, which will cause skin allergies; The glue dries out and the ion mobility decreases, making the electrodes non-conductive

Embodiment Construction

[0019] Such as figure 1 Shown is a block diagram of a myoelectric prosthesis control device. The myoelectric prosthesis control device includes an acquisition module 10 , a preprocessing module 20 and a control module 30 connected in sequence. The collection module 10 is worn on the residual limb of the human body, and is used for collecting the electromyography signal at the residual limb. The preprocessing module 20 preprocesses the electromyographic signal, so that parameters such as the strength of the electromyographic signal meet the requirements for controlling the prosthesis. The control module 30 controls the prosthesis according to the processed myoelectric signal.

[0020] The electromyography signal is collected by contacting the electrodes with the skin. In this embodiment, the collection module 10 includes fabric electrodes. Such as figure 2 Shown is a top view of the structure of the collection device of an embodiment. Two side-by-side fabric electrodes 12...

Abstract

The invention relates to a myoelectric artificial limb control device. The device comprises an acquisition module, a pre-processing module for pre-processing a myoelectric signal acquired by the acquisition module, and a control module for controlling an artificial limb based on the processed myoelectric signal, wherein the acquisition module comprises a textile electrode; and the textile electrode has high conductive property, and keeps properties such as permeability, flexibility, foldability and bonding and the like of the textile material. The textile electrode is convenient and comfortable, and can be easily attached to clothing and skin, so that motion artifacts cannot be generated due to relative displacement.

Description

【Technical field】 [0001] The invention relates to artificial limb control, in particular to a myoelectric artificial limb control device. 【Background technique】 [0002] Prosthetic limbs are artificial limbs manufactured and assembled for amputees to make up for lost limbs and compensate for some of their functions. The widely used artificial limbs include mechanical cable-controlled prostheses, myoelectric prostheses and myoelectric cable-controlled hybrid prostheses. [0003] Mechanical cable-controlled prosthetics use the prosthesis user's own force source to pull the rope or chain through the mechanical action of the residual limb to control the elbow joint and hand device of the prosthesis. Due to the inherent limitations of control methods, mechanical cable-controlled prosthetics have problems such as single function, slow manipulation, clumsy movements, and difficult maintenance. [0004] Myoelectric prosthetics (for example, Otto Bock in Germany and Shanghai Keshen...
