Wherein the first electrode sheet 41 is used for monitoring the electrode RA and picking up the electric signal RA; the third electrode piece 43 is used for monitoring the electrode V1 and picking up the electric signal V1; the second electrode pad 42 is used for the reference electrode RLD. The second electrode plate 42 is used as a reference electrode, so that the anti-interference effect can be achieved in the monitoring process, and the monitoring signals of other monitoring electrodes are more accurate.

More specifically, the first electrode plate 41, the second electrode plate 42, the third electrode plate 43, the fourth electrode plate 44 and the fifth electrode plate 45 are conductive silver paste layers, and silver chloride paste is printed on a PET film to form the electrode, wherein the Ag content is 60% -70% and the AgCl content is 5% -18%.

The adhesive layer is non-conductive, and when not in use, the adhesive layer and the conductive adhesive layer are covered with release paper, and when in use, the release paper is torn off, so that the patch sensor can be attached to a human body, and the collector 8 is attached to the connecting area 3. The conductive contacts 7 and the electrode plates face to two opposite sides of the patch sensor respectively, and the conductive contacts 7 are not directly and electrically connected with a human body. The conductive contact 7 is an elastic conductive element, which has elasticity so as to be electrically connected with the collector 8, and can be conductive foam or conductive elastic sheet. In other cases, the conductive contact 7 further comprises a conductive silver paste layer which is arranged like the electrode plate, the conductive silver paste layer is connected with the conductive piece 91, and the conductive piece 91 and the conductive silver paste layer form the conductive contact 7 together, so that the connection of the conductive contact 7 and the electrode plate is facilitated, and the conductive piece 91 can also adopt conductive foam or conductive elastic pieces, so that the conductive contact 7 forms an elastic element.

As shown in fig. 3, five connection contacts 81 are disposed on one side of the collector 8 near the connection area 3, and after the collector 8 is adhered to the glue layer coated on the connection area 3, the five connection contacts 81 are connected with the five conductive contacts 7 in a one-to-one correspondence manner, so that the electrocardiograph signals picked up by the first electrode sheet 41, the second electrode sheet 42, the third electrode sheet 43, the fourth electrode sheet 44 and the fifth electrode sheet 45 are transmitted to the collector 8 through the flexible circuit 6. In this embodiment, the collector 8 is connected with the connection area 3 through a pasting mode, so that the connection is convenient, the connection is firmer, and the shaking is not easy.

The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto.
