Problems solved by technology

The current ECG electrodes mostly use solid metal sheet electrodes, which do not fit well with the skin with uneven surface shapes, thus affecting the detection effect of the electrodes
In addition, although disposable ECG electrodes are small in size and easy to use, they consume a lot of electrode materials, resulting in a waste of resources

Embodiment 1

[0026] Embodiment 1 Piston-type liquid metal ECG electrode sheet

[0027] The schematic diagram of the overall structure of the piston-type liquid metal ECG electrode provided in this embodiment is shown in figure 1 . The liquid metal ECG electrode sheet 1 can be divided into upper and lower layers: the upper layer is a cylindrical upper layer storage chamber 2 located in the center, the center of the upper layer storage chamber is a connecting wire 3 that runs through the entire electrode sheet, and the center of the lower layer is a conical lower layer contact chamber 4. When in use, the liquid metal 9 is filled with direct contact with the skin. The lower peripheral circular area is an adhesive layer 5. When not in use, the surface is covered with a PVC film. When in use, the PVC film is peeled off and pasted on the skin surface.

[0028] See figure 2 . The upper storage chamber 2 is a movable chamber with variable volume. In this embodiment, a movable piston is used to...

Embodiment 2

[0029] Embodiment 2 Air bag type liquid metal ECG electrode sheet

[0030] The schematic diagram of the overall structure of the gas bag type liquid metal ECG electrode provided in this embodiment is shown in image 3 . The liquid metal electrocardiogram electrode piece 1 can be divided into upper and lower layers: the upper layer is a spherical elastic air bag 8 with openings up and down, filled with liquid metal 9; the air bag 8 is connected downwards with the lower contact chamber 4, and the lower contact chamber 4 It is a conical cavity; the connecting wire 3 is inserted from the upper opening of the airbag 8, and enters the lower contact cavity 4 through the lower opening of the airbag 8; the lower peripheral circular area is the adhesive layer 5.

[0031] See Figure 4 . When using the electrode sheet, apply the electrode sheet on the surface of the skin and then squeeze the airbag 8 so that the liquid metal 9 inside enters the lower contact chamber 4 and contacts the...

Abstract

The invention provides a liquid-metal electrocardio-electrode slice. The liquid-metal electrocardio-electrode slice is of an integrated structure, the electrode slice is in a round shape and divided into two layers along a central axis, a storage cavity (2) is formed in the upper layer, a contact cavity (4) is formed in the lower layer, the capacity of the storage cavity is changeable, the storagecavity is filled with liquid metal, the contact cavity is a conical hollow cavity made of deformable elastic material, and when the electrode slice is in use, the liquid metal in the storage cavity enters the contact cavity, so that the liquid metal is in direct contact with skin; an adhesive layer (5) is arranged in an annular area of the outer periphery of the contact cavity; a wire (3) locatedat the center of the electrode slice penetrates the storage cavity and the contact cavity, when the electrode slice is in use, the lower end of the wire is soaked in the liquid metal, the other end of the wire extends outwards from the center of the storage cavity and is used for being connected with a detection instrument. The liquid-metal electrocardio-electrode slice is provided with good flexibility and can be completely attached to the skin of a user, so that a contact area of an electrode is effectively improved; moreover, a design of movable cavities is adopted so that the electrode slice can be used repeatedly.

Description

technical field [0001] The invention relates to the field of medical materials, in particular to a liquid metal electrocardiographic electrode sheet. Background technique [0002] There are various bioelectrical signals in the living body, the most common of which is the electrocardiographic signal, and the detection of the electrocardiographic signal is of great significance for the diagnosis of cardiovascular diseases. The current in the organism is ionic conduction, while the current in the electrodes and detection instruments is electronic conduction, so the ionic conduction in the organism must be converted into the corresponding electronic conduction through the electrodes. The skin of the human body is equivalent to a semi-permeable membrane of ions, with a certain potential difference, and the metal and skin realize the transformation from ion conduction to electron conduction through oxidation-reduction reaction in the electrolyte environment. The traditional ECG e...
