Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a fixing and protecting device for electrophysiological monitoring needle puncture. Background Art
[0002] Electrophysiological examinations include many types, such as electrophysiological examinations of the heart, brain, muscles, etc., which reflect the physiological abnormalities of the corresponding organs and tissues through electrophysiological changes; the commonly used electrophysiological examination method is percutaneous puncture and electrode catheter insertion technology; electromyography (EMG) uses an electromyograph to record the bioelectric activity of nerves and muscles, and measure and analyze its waveform to understand the functional status of nerves and muscles, and assist in the diagnosis of lower motor neuron or muscle diseases; there are three commonly used methods: ① Needle electromyography: also known as ordinary electromyography, is to insert a special needle electrode into the muscle belly, or use a surface electrode on the skin on the surface of the muscle, and observe the muscle at rest, light contraction, and heavy contraction on an oscilloscope or recording paper. ② Nerve conduction velocity measurement: namely, motor nerve conduction velocity (MCV) and sensory nerve conduction velocity (SCV); pulse stimulation is given at the proximal end (MCV) or distal end (SCV) of the nerve trunk, and the waveform is received at the distal effector muscle (MCV) or the proximal nerve course (SCV). The latency and distance between the two points are measured, and the motor nerve or sensory nerve conduction velocity can be calculated, which is mainly used to understand the nerve conduction function; others: such as repetition frequency test, F wave, H reflex, stretch reflex test and single fiber electromyography test, etc., to further understand the functional status of nerves, muscles, neuromuscular junctions and spinal reflex arcs.
[0003] To sum up, the current electrophysiological monitoring process has the following technical problems: the existing electrophysiological monitoring needle is not fixed after puncture, which causes the electrophysiological monitoring needle to fall off, affecting the monitoring effect. Medical staff need to find a fixing sticker to fix the position of the puncture needle, which makes the operation cumbersome and the position of the puncture needle unstable. In addition, the electrophysiological monitoring needle falls off and causes harm to medical staff due to the slender and sharp needle tip. Utility Model Content
