Fig. 1 shows a schematic plan view of an electrode patch 100 according to an embodiment of the present application.

Electrode patch 100 includes a substrate 110 and at least 3 electrode arrangements 120.

The substrate 110 is a main body of the electrode patch 100, and is generally provided in a flexible sheet shape, and is attached to the skin of the human body as a main body for carrying the electrode device and fixing the position of the electrode device 120 on the substrate.

The electrode device 120 is disposed through the substrate 110, and the proximal end thereof is generally a planar structure for contacting with the skin of a human body and collecting electrical signals of the skin, wherein the electrical signals include electromyographic signals or electroencephalographic signals. The distal end of the electrode arrangement 120 is operatively connected to the brain electrical acquisition device and transmits the electrical signal thereto. In some implementations, the distal end of the electrode device 120 may have attached thereto a lead or other connector further connected to the brain electrical acquisition apparatus; in some implementations, the distal end of the electrode apparatus 120 may also be directly attached to the brain electrical acquisition device.

Fig. 3 shows a schematic structural diagram of an electrode device according to an embodiment of the present application, and the electrode device 120 will be described in further detail below.

The electrode device 120 includes an external terminal 121, a connection mechanism 122, and a conductive medium 123.

The external terminal 121 is usually disposed at the distal end of the electrode device 120, since in the present embodiment, the electrode device is disposed through the surface of the substrate 110, and the external terminal 121 is disposed at the distal surface of the substrate for connecting to the brain electrical acquisition device.

The connection mechanism 122 is a connection body of the external terminal 121 and the conductive medium 123, and is generally disposed on the proximal surface of the substrate 110, and the distal end thereof is operatively coupled to the external terminal 121, so as to form a structure in which the external terminal 121 and the connection mechanism 122 sandwich the substrate 110, which can make the electrode patch more stable and firm. The connecting structure 122 is used for conducting the human body electrical signal collected by the conductive medium 123 and transmitting the electrical signal to the external terminal 121, and further transmitting the electrical signal to the electroencephalogram collecting device through the external terminal 121.

The conductive medium 123 is disposed on the proximal surface of the connection mechanism 122, and is usually made of a flexible material with excellent conductivity, and is used for directly contacting with the skin of a human body to collect an electroencephalogram signal, and then the electroencephalogram signal is transmitted to an external terminal by the connection mechanism having a connection relationship with the conductive medium.

In some embodiments, the at least 3 electrode arrangements 120 are as shown in fig. 1, 2. One of them is a reference electrode device, the potential of which comes from the potential provided by the electroencephalogram acquisition equipment, and the potential is set to 0. The other 2 electrode units are detection electrode units, the electric potential of which is provided by brain electrical equipment, the electric potential is set to positive electric potential and negative electric potential, so that a waveform image, namely brain wave, can be formed by the reference electrode and the two detection electrodes.

In some embodiments, the external terminal 121 is specifically configured as a male buckle, as shown in fig. 3 or fig. 4, the connecting mechanism 122 is specifically configured as a rivet buckle, and the external terminal is connected to the connecting mechanism 122 by riveting, which is more suitable for the operation of the electrode device, and can reduce the complexity of the operation and improve the practicability.

In some embodiments, the external terminal 121 is made of a conductive metal material, as shown in fig. 3 and 4, for transmitting brain electrical signals and myoelectrical signals with high efficiency and quality. The connection mechanism 122 is a flexible member made of plastic material, and the surface of the flexible member is plated with a conductive silver chloride coating to be suitable for coupling with the external terminal 121, the conductive medium 123 and the substrate 110.

In some embodiments, the conductive medium is specifically configured as a conductive hydrogel, as shown in fig. 3, 5. The conductive hydrogel is in a sticky gel state, does not hurt the skin of a human body, has certain conductivity, can convert electroencephalogram signals generated by the scalp into specific electric signals through ion migration change inside the gel, and transmits the specific electric signals to the electroencephalogram acquisition equipment through the connection relation between the external terminal male buckle and the connecting mechanism riveting buckle.

In some embodiments, the edge of the substrate 110 is provided with at least one protrusion 111, as shown in fig. 1, 5. The projections 111 are in some implementations formed by elongated projections of the substrate 110 for the operation of removing the electrode patch 100. In some implementations, the protrusion 111 may also be a separate component disposed at an edge of the substrate 100, and may be directly connected or may be coupled by other connecting components. The substrate 110 is further provided with at least one through hole 112 for increasing the air permeability of the electrode patch and facilitating real-time observation of the use state of the electrode patch.

In some embodiments, the substrate 110 may be made of non-woven fabric, which is soft and has good flexibility, and is suitable for being used as a carrier for adhering to the skin and carrying the electrode device 120. The non-woven fabric, i.e., the proximal surface of the substrate 110, is provided with a double-sided adhesive tape, which can prevent the electrode patch from falling off accidentally during use.

In some embodiments, the electrical signal is specifically an electroencephalogram signal, that is, the electrode patch according to the embodiment of the present application is more suitable for acquiring an electroencephalogram signal. In a specific practical application, the number of the electrode devices 120 is set according to practical conditions, and the method can be widely applied to a dual-channel electroencephalogram acquisition instrument.
