Electrode plate for collecting electroencephalogram signal of anesthesia depth monitoring equipment

Abstract

The invention discloses an electrode plate for collecting an electroencephalogram signal of anesthesia depth monitoring equipment. The electrode plate includes a hard film, round foam and an arc-shaped plate; the upper end of the hard film is in semicircle, and the left and right sides on the lower end of the hard film are in arc shapes; the bottom of the hard film is fixedly connected to the topof the round foam through connecting foam; the central part of the hard film is fixedly connected to conductive paste, and the outside of the conductive paste is provided with an annular double-facedadhesive tape; one side of the annular double-faced adhesive tape is fixedly connected to the hard film; the two ends of the arc-shaped plate are in telescoping connection with arc-shaped rods; the arc-shaped rods and the arc-shaped plates form a ring matching a head; and the connecting foam is detachably connected to the inside of the arc-shaped plate. Through the electrode plate, working personnel can conveniently locate the electrode plate on the head of a patient, so that convenience can be brought for the working personnel.

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...

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
