An electrode fixing device

Abstract

The invention discloses an electrode fixing device, comprising: a fixing base and a vacuum chuck, the fixing base is connected to the back of the vacuum chuck and partly protrudes to the suction surface of the vacuum chuck, the end of the fixing base located on the suction surface of the vacuum chuck is There is a fixed groove at the top, the electrode is detachably installed in the fixed groove and is sealed with the fixed groove, and the distance from the outer end of the electrode to the apex of the arc-shaped surface of the vacuum chuck is less than the distance to the edge of the arc-shaped surface. The connecting wire extends out of the back of the vacuum cup through the mount. The electrode fixing device with the above-mentioned structure can meet the needs of infants' electroencephalogram examination, accurately and stably position the electrodes, and is easy to operate.

Description

Technical field [0001] The present invention relates to the field of electrode examination techniques, and more particularly to an electrode fixation device. Background technique [0002] EEG modern medical practice, now many hospitals are often set up to newborn, premature babies, also set up EEG inspection projects to ensure infants' health. Before recording the EEG, it is necessary to secure the electrode on the scalp, while the accuracy and stability of the electrode position will directly affect the quality of the electroencephalogram, if the electrode is fixed, displacement during the inspection process, The interference is continuously connected, so that the electrocardiogram that records will be not referred to. [0003] In an adult electrode examination, most is to first secure the plurality of electrodes to the corresponding position of the head by tape adhesive manner, and then reinforce the electrodes in the head, and the electrodes are different from the head size.

Problems solved by technology

Before recording the EEG, it is necessary to fix the electrodes on the scalp, and the accuracy and stability of the electrode position will directly affect the quality of the EEG recording. If the electrodes are not fixed firmly, there will be displacement during the inspection process Causes continuous interference, so the recorded EEG will have no reference value at all

[0003] In the EEG examination of adults, multiple electrodes are usually fixed on the corresponding positions of the head by adhesive tape first, and then covered with a mesh cover on the head to further reinforce the electrodes. It is extremely inconvenient to adjust the operation on the patient's body, time-consuming and laborious, the fixation effect is not satisfactory, and it is very unsightly

However, if this electrode fixation method is transplanted to newborns, because babies are active and their behavior is not as easy to control as adults, the electrodes will be more likely to shift, which will bring more inconvenience to the EEG.
