Description

A heart and brain electromyography detection device

technical field

The invention relates to the field of medical equipment, in particular to a heart and brain electromyography detection device.

Background technique

In each cardiac cycle, the heart is excited successively by the pacemaker point, atrium, and ventricle, accompanied by changes in bioelectricity, which are called ECG. Like ECG, there is no harm or pain at all when sticking electrodes on the skin. Electrical skin activity is generated by sweat gland activity, so it is also called sweat gland potential. There are two ways to measure electrical skin activity: one is fee Lee (CharlesFere) with the help of the method of external power supply, this method measures the change of skin resistance (measurement unit is ohm or its reciprocal mho) between two electrodes, which is usually expressed by EDR (F); another One is the method of J. Tarchanoff, which measures the change of skin potential (the unit of measurement is volt-level voltage), which is represented by EDR (T). Generally, when performing EEG detection, the well-known 10-20 EEG electrode configuration method (International 10-20 System) is used, which has become an international standard because of its extremely high reproducibility and accuracy. For division, the vertical line of the head is based on the root of the nose (nasion) and the occipital protuberance (inion), and the total distance is divided into six categories: 10%, 20%, 20%, 20%, 20% and 10%. Part, from front to back are Fpz, Fz, Cz, Pz, Oz positions; the horizontal line of the head is based on the Pre-Auricular Point on the left and right sides, and the total distance is divided into 10%, 20%, 20%, 20%, 20%, and 10% of the six parts, from left to right are T3, C3, Cz, C4, T4 positions; the head circumference refers to the connection line of Fpz, T3, Oz, and T4, where , the left half is divided into six parts from front to back: 10%, 20%, 20%, 20%, 20%, and 10%, which are respectively Fp1, F7, T3, T5, and O1 positions, and the right half is also from front to back It is divided into six parts of 10%, 20%, 20%, 20%, 20%, and 10%, which are respectively Fp2, F8, T4, T6, and O2 positions.

According to the common EEG, EMG and ECG detection forms, the number of electrode wires connected to the user is quite large (the number varies according to different measurement purposes), for example, the general basic 16-channel EEG detection At least 18 electrode wires are required. Myoelectricity and ECG also require a large number of electrode wires, and as the number of channels increases, the number of electrode wires must also increase. In addition, these electrode wires must be connected to the side Therefore, the disadvantage of this type of brain, muscle, and ECG detection device is that the mobility of the user is highly restricted, and it is easy to pull the electrode wires.

In addition, existing product heart rate testing, electromyography, and electrodermal testing require separate equipment testing. Interference between equipment will affect data accuracy when testing users, and multiple sets of equipment and electrodes are large in size and complicated to connect. The user experience is not good.
