Description
Technical field
The invention belongs to technical field of medical instruments, relate to the lead electrode of brain electricity series products, be used for the collection and the transmission of EEG signals, is a kind of ear electrode specifically.
Background technology
Existing ear electrode is widely used in homemade, import electroencephalograph, is used for the collection and the transmission of EEG signals.Existing ear electrode comprises metal electrode, clip, and described clip comprises hinged last grip block and following grip block and spring.But also there are the following problems and deficiency for existing ear electrode:
1, ear electrode body structure is the plastic grip that corner angle are arranged, and the acquired signal electrode of ear electricity folder contacts for point with patient, when clinical use, easily patient body is produced damage or sense of discomfort.
2, ear electrode clip profile is comparatively roomy square, easily with patient contacting except that the detection position is taken place.
3, adopt copper electrode or stainless steel electrode.Easily produce polarizing voltage, take the sensitivity of signal lower, the drift time of signal is longer.
4, the cable junction of ear electrode lacks protection, influences service life.
5, clamping place of ear electrode clip is an even surface, and the phenomenon of sliding hands easily takes place when medical personnel are used.
How to design a kind of ear electrode, it is rational in infrastructure, can not cause damage or sense of discomfort to patient, uses easy to operately, improves the sensitivity take signal, reduces the drift time of signal, increases the service life.This is the technical problem that needs to be resolved hurrily at present.
Summary of the invention
The present invention provides a kind of ear electrode for solving the problems referred to above that prior art exists, and it is rational in infrastructure, can not cause damage or sense of discomfort to patient, uses easy to operate.In addition, can improve the sensitivity of taking signal, reduce the drift time of signal, increase the service life.
The objective of the invention is to be achieved through the following technical solutions:
A kind of ear electrode comprises metal electrode, clip, and described clip comprises hinged last grip block and following grip block and spring, and grip block is the Fructus anacardii shape to it is characterized in that reaching down by described upward grip block, and the grip block lateral surface was the cambered surface of slyness under last grip block reached.
To improvement of the technical scheme: described going up on the anterior clamping face of grip block is provided with projection, the end face of described projection is the plane, the anterior clamping face of described grip block down is an inner concave, described metal electrode is the plate shaped metal electrode that is arranged on the inner concave bottom, plate shaped metal electrode connects a cable one end, and described cable passes down grip block and stretches out from following grip block rear end.
To further improvement in the technical proposal: described projection is round table-like, and described inner concave and round table-like projection are coincide.
To further improvement in the technical proposal: described upper and lower grip block rear end finger grips concavo-convex anti-skidding stricture of vagina is set on the face.
To further improvement in the technical proposal: described metal electrode is the integrative-structure that fine silver or silver chloride are made.
To further improvement in the technical proposal: described cable stretches out one section from grip block rear end down and is with protecting tube.
To further improvement in the technical proposal: described upper and lower grip block is injection molding.
The present invention compared with prior art has the following advantages and good effect:
1, the upper and lower grip block of ear electrode clip of the present invention all adopts Fructus anacardii shape, and good looking appearance is easy to use, is difficult for patient contacting except that detecting the position being taken place.The skin that cusped edge damages patient can not appear in the slick and sly cambered surface design that the upper and lower grip block lateral surface that contacts with human body skin adopts, and is difficult for making patient produce sense of discomfort yet.Simultaneously, also solved the signal drift problem that causes because of the clip surfaces burr.
2, the plate shaped metal electrode and the patient of acquired signal of the present invention adopt plane contact, have avoided the damage of some contact to patient body.
3, the present invention adopts fine silver or silver chloride to do electrode piece, copper electrode or stainless steel electrode before having replaced.Thereby reduced polarizing voltage, improved the sensitivity of taking signal, shortened the drift time of signal.
4, the cable junction of ear electrode of the present invention connects protecting tube, with the connecting portion of clip, increases the service life in the protection cable.
5, the present invention grips at upper and lower grip block rear end finger concavo-convex anti-skidding stricture of vagina is set on the face, and the phenomenon of sliding hands can not take place when medical personnel are used.
Description of drawings
Fig. 1 is the front view of ear electrode of the present invention;
Fig. 2 is the vertical view of ear electrode of the present invention;
Fig. 3 is the axonometric chart of ear electrode of the present invention.
The specific embodiment
Referring to Fig. 1-Fig. 3, be the embodiment of a kind of ear electrode of the present invention, comprise metal electrode, clip, described clip comprises hinged last grip block 1 and following grip block 4 and spring.Grip block 4 was the Fructus anacardii shape under described upward grip block 1 reached, and the lateral surface of grip block 4 was the cambered surface of slyness under last grip block 1 reached.
On last grip block 1 anterior clamping face, protruding 1-1 is set, the end face of described protruding 1-1 is the plane, described grip block 4 anterior clamping faces down are inner concave, described metal electrode is the plate shaped metal electrode that is arranged on the inner concave bottom, plate shaped metal electrode connects a cable 3 one ends, and described cable 3 passes down grip block 4 and stretches out from following grip block 4 rear ends.Described metal electrode is the integrative-structure that fine silver or silver chloride are made.
