Examples
The embodiment discloses a conductive hydrogel electrode patch, and the conductive hydrogel electrode patch 3 includes: the bioelectricity-sensing patch comprises a metal electrode 1, an elastomer cover 2 and a central processing unit, wherein the metal electrode 1 is arranged on the back of a patch 3, the elastomer cover 2 is sleeved around the metal electrode 1, conductive hydrogel is filled in the elastomer cover 2, and the central processing unit is connected with the metal electrode 1 and is used for collecting and processing bioelectricity signals of a human body.
The elastomer cover 2 is horn-shaped as a whole, the tail part of the elastomer cover 2 surrounds the metal electrode 1, and the horn mouth of the elastomer cover 2 is opened outwards. When the elastomer cover 2 contacts with the human body, because the whole body is in a horn shape, the contact surface of the horn mouth and the skin is larger, and perfect fit can be realized. The elastomer cover 2 is provided with two layers, a containing cavity is formed inside the elastomer cover 2, and conductive hydrogel is injected into the containing cavity inside the elastomer cover 2. After the elastomer cover 2 is filled with the conductive hydrogel, when the metal electrode 1 is contacted with the skin of a human body, the elastomer cover 2 is attached to the skin of the human body. In this embodiment, the elastomer cover 2 can be made of soft silica gel, and can be perfectly attached to the human body.
The conductive hydrogel flows freely in the elastomer cover 2, and when the elastomer cover 2 is contacted with the skin of a human body, the conductive hydrogel flows according to the shape of the part jointed with the human body and is tightly jointed with the skin. Different parts of a human body are different in shape, the traditional electrode patch 3 is difficult to adapt to the requirements of different parts for fitting, and the situation of falling or untight adhesion is easy to occur, so that the detection result is seriously influenced.
In the embodiment, the conductive hydrogel can freely flow in the elastic body, and can freely flow according to different shapes of different parts of a human body, so that the conductive hydrogel is perfectly attached to the parts of the human body, and the shape is not limited. The metal electrode 1 is ensured to be in close contact with the human body, and the accuracy of data acquisition is ensured.
The central processing unit is connected with the metal electrode 1, the metal electrode 1 induces the human body bioelectricity signal, and sends the human body bioelectricity signal to the central processing unit for filtering, impurity removal and amplification, and the bioelectricity signal is judged. And the central processing unit collects different types of bioelectricity signals according to actual requirements and analyzes the bioelectricity signals. The double faced adhesive tape is arranged on one side of the patch 3, which is the same as the metal electrode 1, and when the metal electrode 1 is contacted with the skin of a human body, the patch 3 is fixedly adhered to the human body through the double faced adhesive tape, so that the patch is prevented from falling off.
The utility model discloses a conductive hydrogel electrode paster sets up elastomer cover 2 around metal electrode 1, pours into conductive hydrogel in elastomer cover 2, and when metal electrode 1 and human skin contact, conductive hydrogel can laminate with human contact site completely, effectively strengthens the contact of conductive hydrogel and human skin, guarantees that metal electrode 1 accurately gathers human biological electricity signal, avoids leading to the big condition of signal noise because metal electrode 1 and skin contact are bad. And the conductive hydrogel is arranged in the elastomer cover 2, so that volatilization of the hydrogel in the elastomer cover can be prevented, and the limited service time can be prolonged.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
