Embodiment Construction

[0017] The specific embodiments of the present invention will be described below with reference to the drawings.

[0018] Such as figure 1 As shown, two rotating positioning needle electromyographic electrodes 10 form a set to form a set. The rotary positioning needle electromyographic electrode 10 includes a fixed ring 11, a sliding ring 12 and a plurality of needle electrode assemblies 13.

[0019] The fixing ring 11 is set at the position of the EMG detection, mainly the limbs.

[0020] The sliding ring 12 is sleeved on the periphery of the fixed ring 11 and is rotatably connected with the fixed ring 11.

[0021] A plurality of needle electrode assemblies 13 are arranged along the circumference of the sliding ring 12. A plurality of electrode through holes 14 are opened in the fixed ring 11 along the circumferential direction. The needle electrode assemblies 13 move circularly with the sliding ring 12, and the sliding ring 12 has There is a spring positioning bead, and each time i...

Abstract

The invention provides a rotary positioning needle type myoelectric electrode and a kit thereof. The rotary positioning needle type myoelectric electrode comprises a fixed ring, a sliding ring and a plurality of needle type electrode components, wherein the fixed ring sleeves a myoelectric detection position; the sliding ring sleeves the fixed ring and is rotatably connected with the fixed ring; the needle type electrode components are arranged around the circumference of the sliding ring; a plurality of electrode through holes are formed in the fixed ring along the circumference direction; the needle type electrode components are subjected to circumference movement along with the sliding ring and are mixed with electrode holes in different positions. Through the rotary positioning needle type myoelectric electrode, the other detection position can be repositioned by the sliding ring; needle type electrode tips are used for detecting; the number and the positions of the electrode holes are set in advance, so that the needle applying position is more accurate.

Description

Technical field [0001] The invention relates to a rotary positioning needle type electromyography electrode and a kit thereof, belonging to the field of medical equipment. Background technique [0002] Electromyography (EMG) is a method of using electronic equipment to record the electrical activity of muscles at rest or contraction, and the application of electrical stimulation to check nerve and muscle excitation and conduction functions. [0003] Through this examination, the functional status of peripheral nerves, neurons, neuromuscular junctions and muscles can be determined. [0004] By measuring the time limit and amplitude of motor unit potential, whether there is spontaneous electrical activity in quiet conditions, and the wave pattern and amplitude of muscle contraction, it can distinguish between neurogenic damage and myogenic damage, and diagnose acute and chronic spinal cord damage (Such as poliomyelitis, motor neuron disease), nerve root and peripheral neuropathy (for ...
