An electrode sheet for collecting EEG signals in anesthesia depth monitoring equipment

Abstract

The invention discloses an electrode sheet for collecting EEG signals of anesthesia depth monitoring equipment, which comprises a hard film and a circular foam; the upper end of the hard film is semicircular, and the left and right sides of the lower end of the hard film The sides are all arc-shaped, the bottom of the hard film is fixedly connected with the top of the circular foam through the connecting foam, the center of the hard film is fixedly connected with a conductive paste, and the outer side of the conductive paste is provided with a ring Double-sided adhesive tape, one side of the ring-shaped double-sided adhesive tape is fixedly connected to the hard film; it also includes an arc-shaped plate, and both ends of the arc-shaped plate are telescopically connected with an arc-shaped rod, and the arc-shaped rod and The arc-shaped plate forms an annular shape matched with the head, and the connecting foam is detachably connected to the inner side of the arc-shaped plate. The invention is convenient for the staff to locate it on the patient's head, which brings convenience to the staff.

Description

technical field [0001] The invention relates to an electrode sheet, in particular to an electrode sheet used for collecting electroencephalogram signals of anesthesia depth monitoring equipment. Background technique [0002] In the prior art, the anesthesia depth monitor includes a signal input module, an amplification module, and an analog-to-digital conversion module; wherein, the signal input module is used to receive brain wave electrical signals simulating the cerebral cortex, and the amplification module is connected to the signal input module to convert the signal The brain wave electric signal of the input module is amplified, and the analog-to-digital conversion module is connected with the amplification module for converting the brain wave electric signal of the cerebral cortex into a digital electric signal, and also includes a calculation module, and the calculation module is connected with the analog-to-digital conversion module for converting the obtained The c...

AI Technical Summary

Problems solved by technology

However, the current existing sensors generally have local defects; for example, the electrode sheet needs to be pasted on the forehead, ear root and temple top of the patient's head during use, and the staff needs to paste it separately, thus wasting the time of the staff. It is generally inconvenient to control the position between the three electrode sheets when pasting separately. If the position between the electrode sheets is not pasted accurately, it will affect the correctness of the detection data
