Square paper type electrode positioning method for newborn baby

Abstract

The invention discloses a square paper type electrode positioning method for a newborn baby. The method comprises the steps that firstly, medical paper adhesive tape passes through the center of the top of the head from the nasion portion and adheres to the external occipital protuberance portion, the length of the adhesive tape is measured, and a central point is drawn and serves as a Cz central point; according to the length of the adhesive tape, 40% of the adhesive tape is taken to form square adhesive tape by cutting and the central angle of the square adhesive tape is cut off after the square adhesive tape is folded in half; a cross is drawn and passes through the central point; the adhesive tape passes through the middle of the top of the head from the nasion portion again and adheres to the occipital bone portion; the center of the square adhesive tape is aligned with the central point drawn on the adhesive tape, the angles of the two ends of the cross are an Fz electrode position and a Pz electrode position respectively, and the four corners of the square adhesive tape are an F3 electrode position, an F4 electrode position, a P3 electrode position and a P4 electrode position respectively. The method is simple in operation and capable of saving time and being implemented by all medical staff; the number of steps is small, errors are reduced, and electrode positioning is accurate; the method is suitable for newborn babies with various diseases, accords with the international 10-20 positioning method, enables the electrode positions to be obtained by measurement and effectively solves the problem that electrode positioning of the newborn baby is difficult.

Description

technical field [0001] The invention relates to a newborn electroencephalogram electrode positioning method, in particular to a newborn square paper electrode positioning method. Background technique [0002] EEG is to amplify the spontaneous bioelectric activity of brain neurons by 1 million times by placing appropriate electrodes and with the help of electronic amplification technology, and convert pulsed direct current into alternating current and record the brain electrical activity. Different electrodes represent different local locations. The International 10-20 system has become the standard method used worldwide except for newborns. The use of F3-P3 and F4-P4 is recommended in Amplitude-Integrated EEG of the Newborn, co-edited by Lena Hellstrom-Westas Linda S de Vries Ingmar Rosen. But how to get these four electrode positions? Many clinical units use the 10-20 system connection method. [0003] 10-20 system connection method, such as figure 1 Shown: [0004] ①...

AI Technical Summary

Problems solved by technology

[0008] The 10-20 system connection method can effectively locate older children and adults, but it is more difficult for newborns: 1) The head circumference is small, which is inconvenient to measure; 2) Newborns do not cooperate with the measurement; 3) The measurement points need 21 points, A lot of time wasted; 4) The operation is troublesome; 5) The diagnosis time is delayed; 6) It is not suitable for children with critical illness, endotracheal intubation, respiratory disease, heart disease, etc.; 7) The operation requires professional and technical personnel

[0009] Some manufacturers have introduced the method of electrode caps. This method exists: 1) The gas permeability of the electrode cap is not high; 2) It is prone to crushing; 3) It cannot satisfy the accurate positioning of the electrode position for each head circumference; 4) The high impedance cannot reach the international 5 1,000 ohms; 5) Not suitable for children with critical illness, endotracheal intubation, respiratory disease, heart disease, etc.; 6) Cannot be used for long-term EEG examination

[0010] The EEG manufacturer recommends the tape measure method to measure the central line from the left earbone to the right earbone, and extend to measure C3-C4, P3-P4, F3-F4. This method has: 1) inaccurate measurement; 2) inaccurate Fixed electrode position; 3) It is not conducive to the location of the lesion; 4) The EEG image is asymmetrical, which is not conducive to diagnosis; 5) It does not conform to the international 10-20 system positioning; 6) The practical limit is 4 electrode positions
