Multi-lead medical flexible electrode slice using conductive silver paste as carrier

Technical Field

The utility model relates to a multi-lead medical flexible electrode slice using conductive silver paste as a carrier, belonging to the field of wearable medical instruments.

Background

The existing equipment for performing the electrocardiogram measurement on the market mostly uses a reusable electrocardiogram lead wire and a disposable electrode plate matched with the same, has large volume, is inconvenient to carry, is uncomfortable to wear and is not suitable for being worn for a long time, and is easy to cause measurement deviation due to small-amplitude activity; in some occasions without nursing of medical staff, patients are easy to operate by mistake or fall off during movement, and the patient monitoring system is not suitable for long-time dynamic monitoring. Under the social environment of rapid development, people pay more and more attention to the requirements of comfort and portability, and the existing lead wire cannot meet the use requirements of users.

Disclosure of Invention

The utility model aims to overcome the not enough of current electrocardio lead line, provide one kind and can satisfied different users, the application demand of different scenes can carry out long-time dynamic guardianship, and can improve the travelling comfort to guardianship patient, simple manufacture is fit for industrial production, the low medical flexible electrode piece that leads that uses electrically conductive silver thick liquid as the carrier of processing cost.

The utility model aims at accomplishing through following technical scheme, an use conductive silver thick liquid as the medical flexible electrode piece of carrier, it includes medical grade TPE, PU film and the like material as the substrate, the substrate above have conductive silver thick liquid layer through screen printing technique silk screen printing, and conductive silver thick liquid layer the higher authority be fixed with the contact electrode of evagination, can acquire human electrocardiosignal at a certain distance.

Preferably, the method comprises the following steps: the base material is a medical TPE film, the thickness of the film is 0.08-0.20mm, the folding diameter is 120-750 mm, the hardness is Shore 65A, the longitudinal stretching force is 30 Newton, the transverse stretching force is 18 Newton, and the film has the characteristics of good air permeability, extensibility, flexibility, no static electricity and the like; the conductive silver paste is in a light gray liquid state, the weight ratio of particles is less than 15 mu M, the sheet resistance of the paste is less than 15 MOmega, and the solid content is 65 +/-5%; it can be widely used for printing flexible circuit, and has good printability, conductivity, oxidation resistance and strong adhesive ability.

Preferably, the method comprises the following steps: the substrate is made into at least one of a strip shape, an arc shape or an arch shape, the contact electrode is at least fixed on two end points of the substrate, the substrate is an upper layer and a lower layer and is glued together, the conductive silver paste layer is sandwiched between the two layers of the substrate, and the contact electrode is exposed on the upper surface of the upper layer of the substrate.

The utility model discloses a pass through screen printing's technique silk screen printing with electrically conductive silver thick liquid on the medical grade film material such as TPE, PU that thickness is 0.08-0.20mm, human electrocardiosignal is acquireed through purpose-made contact electrode contact human body, and its electrically conductive silver thick liquid has good electric conductivity to have good toughness and adhesive force through the cooling after the liquid mode silk screen printing, be difficult for droing. The test experiment shows that the electrode line can not be disconnected when a human body slightly moves, so that the measurement fails, compared with an electrocardio lead line, the interference on the measurement of electrocardio in the movement is greatly reduced because the electrocardio lead line is attached to the human body, and meanwhile, the used conductive silver paste has high oxidation resistance and good stability when being in long-time contact with the human body or exposed in the air. The lead electrode plate suitable for various human bodies and shapes can be manufactured according to the series of characteristics, and the application range is wide; and the patient can be replaced after a long-time dynamic monitoring, and the system is safe and sanitary.

The disposable wearable multi-lead medical electrocardioelectrode plate uses silver paste with good conductivity to print on ultrathin TPE, PU films and other flexible materials in a printing mode, and has the advantages of good flexibility, high air permeability, low printing cost, easy operation and the like under the condition of not influencing measurement data acquisition.
