Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.

As shown in fig. 1 and 7, an embodiment of the present application provides an elastic electrocardiograph electrode, which includes a first base liner 1, a conductive line 2, and a second base liner 3, which are sequentially stacked, where the first base liner 1, the conductive line 2, and the second base liner 3 are all stretchable in a first direction, the first direction is a connection line direction of an a end and a B end, i.e., a direction x in fig. 1. The main improvement of the elastic electrocardio-electrode is that the conducting circuit 2 has no base material and is directly attached to the second substrate 1. This structural difference is mainly brought about by technological improvements.

In a possible embodiment, such a substrate-less conductive line 2 is obtained by separating a release film after printing a conductive paste made by adding a cross-linked polymer to silver chloride onto the release film, thereby having a certain elasticity. The conductive line 2 may also be formed by die-cutting an elastic conductive sheet material, such as conductive silicone rubber, a conductive fiber layer, a wave-shaped conductive wire or an elastic conductive film. In both ways, a conductive line 2 without a substrate can be obtained. In the prior art, the transmission lines 2 are printed on a base material, and then the base material is adhered to a base lining. The elasticity of the base material is poor, so that the elasticity of the whole electrode is limited. The elasticity electrocardio electrode that this application embodiment provided owing to do not have the substrate, has eliminated the restriction of circuit substrate to whole elasticity, can be better present self application performance. Meanwhile, due to the fact that structural composition materials are reduced, material cost can be reduced, and the process is simplified. In addition, the use of materials is reduced, and the medical biocompatibility risk can be reduced.

Preferably, the conductive line 2 is a wave-shaped conductive line extending in the first direction, so that better flexibility can be obtained, and deformation can follow deformation of the substrate. The first and

second substrates

1 and 3 are made of an elastic material, such as silicone or polyurethane.

The embodiment of the application also provides a manufacturing process of the elastic electrocardio-electrode, which comprises the following steps:

step 1, printing elastic conductive paste on a peelable release film to form a conductive line, as shown in fig. 2;

step 2, transferring the release film to a colloid surface on a second base liner to enable the conductive circuit to be attached to the second base liner, as shown in fig. 4;

step 3, tearing off the release film, as shown in fig. 5;

step 4, covering a first base lining on the conducting circuit, as shown in fig. 6;

the resulting electrocardio-electrode is shown in fig. 7, and the B end can be coated with a conductive gel 4.

Based on the above manufacturing process, it can be further improved that a plurality of conductive lines 2 are printed on the same release film 5, as shown in fig. 3. Therefore, when the release film 5 is transferred and pasted on the second base lining 3, a continuous roll pasting process can be adopted, and the production efficiency is greatly improved.

As will be readily appreciated, the present application further provides another elastic electrocardio-electrode manufacturing process, including: and die-cutting and molding the elastic conductive sheet to obtain a conductive circuit, attaching the conductive circuit to the second base liner, and covering the conductive circuit with the first base liner.

In summary, the elastic electrocardio-electrode and the manufacturing process thereof provided by the embodiment of the application change the forming process of the transmission line on the basis of using the medical base lining with elastic performance, and change the base line into the non-base line, thereby improving the application stability of the electrode, improving the signal acquisition quality and achieving the purposes of reducing the cost and simplifying the process.
