Description

A kind of EEG electrode helmet

Affiliated technical field

This utility model relates to a kind of electrode placing device when doing EEG (electrocardiogram) examination, especially can simultaneously electrode be placed exactly by quick integral, and electrode can be rubbed beginning with the hands and send out, and injects an amount of electrolyte simultaneously.

Background technology

At present, known electrode cap structure is simple and crude, uses inconveniently, and electrode cap is by rubber tube (bar), the fixing grain of rubber tube (piece) and fixedly frenulum form.Electrode cap is worn on those who are investigated's the head, fasten fixedly frenulum, with rubbing son with the hands the hair stranding of electrode rest is opened, again with wet electrode with arc-spark stand is put and push down with the rubber tube of electrode cap, so one by one all electrodes are placed and finished, folder is gone up corresponding electrode wires then, can carry out EEG (electrocardiogram) examination.The spacing that general electrode cap electrode is placed has very big randomness, and not too accurate, the homogeneity of check result is relatively poor, and electrode is placed trouble one by one, and workload is big, wastes time and energy, and presss from both sides wrong electrode during the folder electrode wires easily, and electrode wires folds up repeatedly, makes easy damage in order.

Summary of the invention

In order to overcome existing EEG electrode medicated cap, inaccurate, trouble that electrode is placed, electrode wires is pressed from both sides mistake, flimsy deficiency easily, the purpose of this utility model provides a kind of EEG electrode helmet, it can not only satisfy the needs of EEG (electrocardiogram) examination, and can lay required electrode simultaneously easily and fast, exactly, and is time saving and energy saving, improve inspection speed, raise the efficiency.

The purpose of the new shape of this practicality is achieved in that the EEG electrode helmet is made up of the helmet and outside synchronous infusion pump, air pump, active efflux, go-cart.The helmet by outer, in, interior three layers constitute, skin is the plastics hemispherical shell, one top box is arranged at the top, the top box external form can be a rectangle or bell, one circular rope fastening hole is arranged at the top box top, fastens with rope, and the other end of rope is fastened counterweight block, hang on the cantilever directive wheel of go-cart, alleviate the heavy burden sense of those who are investigated the helmet.Counterweight block is in the cylindric column tube of ensconcing go-cart.The top box rear portion has power respectively polar curve, tube for transfusion, breather of two pipeline holes to come in and go out.Cover top portion has an apical pore, and the various leads in the shell, conduit all are connected with electroencephalograph, air pump, synchronous infusion pump, the active efflux of outside through the pipeline hole of this hole and top box.The cover top portion internal fixation the passive pump pump housing that respectively there are a piston, connecting rod in a two, the connecting rod of two pistons is the mode to flexibly connect respectively, be connected with the connector at two portable plate tops, on two piston space pump housings a hole is arranged, be connected to form the tube chamber of a sealing through conduit and active efflux.The active efflux reducing motor by crank connecting link, drives the active efflux piston and makes back and forth movement, and intraluminal pressure (air pressure or hydraulic pressure) is changed, thereby drives piston and two portable plate motions in the passive pump.Respectively there is an ear electrode wires hole shell both sides, and ear electrode wires and ear electrode tube for transfusion are therefrom drawn, and receive on the ear electrode.There are two frenulum holes the below in ear electrode wires hole, can install and fix frenulum.There is a circle groove or a multiple spot groove fixed block the antermarginal inboard of shell.Internal layer is a medicated cap shape isolating membrane, and its edge embeds wherein, and medicated cap shape isolating membrane preferably rubber is made, and has on the film and the corresponding a plurality of circular holes of number of electrodes same position, is enclosed within on the flexible electrode outer tube.The middle level is two 1/2 hemispheric portable plates, and both engagement edges are curved, and portable plate respectively has a protrusion for two jiaos, overlaps each other, and the circular hole of a concentric is arranged, and is installed on the portable plate installation cylinder in the shell both sides and can does the motion of branch folding Gansu Province.16 to 64 or more flexible electrode mounting hole are arranged on the portable plate, installation length
