Description
Technical Field
The application relates to the technical field of medical equipment, in particular to a safety protection spiral electrode.
Background
Needle electrodes are a common medical sensing device. When bioelectricity or line electrostimulation is detected, the electrode is a link for connecting or coupling an instrument system with an organism. The purpose of the electrodes is to take electrical signals directly from the organism. When the electrode is used to obtain electric signals from organism, the characteristics of the tested object are different, and the structure of the electrode is different. When the electric potential of the deep part of a single cell or tissue is detected, a microelectrode is adopted; when measuring the electrical activity of a local area of the tissue, a needle electrode is adopted; when measuring the potential of the body surface of the living being, a body surface electrode may be used.
The medical needle electrode is mainly used for clinical diagnosis of patients by certified medical practitioners, and for collecting and transmitting bioelectric signals (electroencephalogram, electrocardio and electromyographic current) of corresponding parts of a human body to a nerve monitor, an electroencephalogram recorder (EEG), an electrocardio recorder (ECG) and an electromyographic current recorder (EMG) in the processes of examination, treatment and operation, and for processing, analyzing and diagnosing. Or sending low-frequency pulse waves emitted by the low-frequency therapeutic apparatus to the skin of a patient to stimulate peripheral nerves and excite and pace the potential of the paralyzed peripheral nerves of the patient so as to judge the physiological state of the nerves. The electrode for collecting the brain nerve electrophysiological signals is mostly a straight needle electrode or a bent needle electrode, so that the operation is convenient and reliable, and the accuracy of signal collection is improved.
The needle-shaped electrode that uses at present mostly is the straight needle, does not prevent stabbing the device, and the condition that stabs other personnel appears before using, after easily, increases risks such as occupational exposure, cross infection. The needle electrode is not easy to control the inserting depth of the needle and is easy to slide from the scalp of a patient, which may cause the collected signal to be intermittent, thereby affecting the accuracy of the collected signal and delaying the illness state of the patient.
