Description

ELECTRODE MODULE FOR MEDICAL APPARATUS -

The present invention relates to an electrode module for a medical device, and more particularly, to an electrode module for a medical device having an electrode which is in close contact with a scalp.

The brain is the internal organs of the human head and is the supreme central organs of the nervous system and is divided into the cerebrum, cerebellum, middle brain, leg brain, and soft tissue.

In addition, the brain generates EEG signals, which are the signals measured in the epidermis of the brain as the sum of neuron activity levels.

As a method for measuring the state of the brain, an EEG (electroencephalogram) test in which a pad having an electrode on the scalp is attached to measure an EEG received from an electrode or a brain is photographed at various angles using radiation or ultrasound CT scans to examine, and MRI scans to photograph the brain by magnetic resonance.

In order to increase the adhesion between the pad and the scalp, the EEG test has conventionally been conducted in which the hair of the subject's scalp is removed, and the EEG is closely attached to the scalp to measure the EEG.

In addition, in order to improve the brain function and treat the ongoing mental disorders, the pad was closely contacted to the scalp of the subject and transcranial direct current stimulation (tDCS) or a transcranial electric stimulation Alternating Current Stimulation (tACS) is being implemented.

In order to increase the degree of contact between the electrodes and the scalp when stimulating the brain by measuring the brain waves or applying current to the brain, electrode modules for medical devices employing protruding electrodes instead of pad electrodes are widely used.

However, since the protruding electrode is not pivotable in the conventional electrode module having the protruding electrode, it is difficult to closely contact the electrode in correspondence with the shape of various head parts when the electrode is brought into close contact with the scalp, The electrode is required to be brought into close contact with the scalp while piercing it, so that the convenience of the user is lowered, and the adhesion between the electrode and the scalp also deteriorates.
