[0028] DETAILED DESCRIPTION

[0029] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0030] The utility model provides an electrode sheet structure which is convenient for testing electrode integrity, comprising a transmission FPC soft row 1, a signal line 2, a detection line 3 and a conductive gel 4; the signal line 2 and the detection line 3 are both conductive silver lines.

[0031] The transmission FPC soft row 1 is connected to the conductive gel 4 through a signal line 2;

[0032] The two ends of the detection circuit 3 are respectively connected to the leftmost pin and the rightmost pin of the transmission FPC soft row 1. The detection circuit 3 and the transmission FPC soft row 1 form a ring structure, and the middle part of the ring structure is arranged around the outer circle of the electrode sheet structure.

[0033] In a preferred example, the transmission FPC soft row 1 is a 5-pin FPC soft row with a reinforcement sheet (i.e., a 5-pin FPC soft row), the number of the conductive gels 4 is 3, and the 3 conductive gels 4 are respectively connected to the middle 3 pins of the transmission FPC soft row 1 through 3 signal lines 2. The 5-pin FPC soft row is used to insert an FPC connector of corresponding specifications to transmit signals.

[0034] According to actual use experience, generally speaking, when the electrode sheet structure is damaged, it will be damaged from the outside first. Therefore, when using the electrode sheet structure provided by the utility model, when the electrode sheet structure is damaged, the detection circuit will be damaged first. Therefore, when it is necessary to determine whether the electrode sheet structure is damaged, the detection can be completed by determining whether the detection circuit is damaged. In addition, in the utility model, the signal line is designed in the center part of the electrode sheet, and the shortest possible line is used to enter the FPC soft row, which reduces the possibility of damage to the signal line and improves the anti-interference ability of the signal.

[0035] The electrode sheet structure for testing electrode integrity also includes a fixing portion 11, a gel portion release film 13 and a fixing portion release film 15; the bottom end of the conductive gel 4 is lower than or equal to the bottom end of the fixing portion 11; the bottom end of the fixing portion 11 is coated with an adhesive, the fixing portion release film 15 is attached to the bottom end of the fixing portion 11, a plurality of openings are provided on the fixing portion release film 15, the positions of the openings correspond to the positions of the conductive gel 4; the size of the openings corresponds to the size of the conductive gel 4; the gel portion release film 13 is attached to the bottom end of the conductive gel 4, the size of the gel portion release film 13 corresponds to the size of the conductive gel 4, or the size of the gel portion release film 13 is larger than the size of the conductive gel 4. The electrode sheet structure for testing electrode integrity also includes a release film ear 16, and both the gel portion release film 13 and the fixing portion release film 15 are provided with a release film ear 16. That is to say, the gel part release film 13 and the fixed part release film 15 are arranged in different areas, that is, the fixed part 11 and the conductive gel 4 are covered by different release films respectively, so that the release film of the conductive gel part (gel part release film 13) can be separated separately, so that the release film of the conductive gel part can be removed first without removing the release film of the fixed part (fixed part release film 15). Therefore, when the conductive gel is exposed, the test is first performed on the user's body surface, and after the test signal is qualified, the fixed part release film is removed for fixing, which improves the common design that the electrode patch has only one deployment opportunity, resulting in an abnormal signal caused by an unreasonable deployment position. The deployment process is reduced, the signal quality can be improved, and the waste of consumables is reduced. In addition, the utility model reserves convenient removal of release film ears for both the gel part release film 13 and the fixed part release film 15, and the operator can remove the release film conveniently and quickly through the convenient removal of the release film ears.

[0036] like Figure 2 The ECG electrode patch supporting repeated alignment also includes a circuit layer 20, an adhesive layer 21 and a non-woven fabric carrier layer 22; the circuit layer 20, the adhesive layer 21, the non-woven fabric carrier layer 22, the fixed part layer 11, and the fixed release film layer 15 are stacked in sequence from top to bottom, the top of the conductive gel 4 is connected to the circuit layer 20, the bottom of the conductive gel 4 is lower than (i.e., exceeds the fixed part 11 from top to bottom) or equal to the bottom of the fixed part 11, and the gel part release film 13 is attached to the bottom of the conductive gel 4. The transmission FPC soft row 1, the signal line 2 and the detection line 3 are all located in the circuit layer 20, and the end of the signal line 2 is connected to the conductive gel 4.

[0037] The utility model is based on the loop principle. Specifically, among the pins of the FPC 5 pin, the loop pins are the leftmost and rightmost pins. After the FPC is inserted into the FPC connector, the leftmost pin and the rightmost pin are inserted, which can be regarded as the FPC cable being inserted in place.

[0038] The principle of the utility model can be simply understood as designing a ring circuit printed with conductive silver paste around the periphery of a traditional electrode sheet, and whether the electrode sheet is damaged can be determined by detecting the conductivity of the ring circuit.

[0039] In summary, the utility model designs the structure of the utility model based on the fact that most electrode sheets will be damaged from the outside when damaged. The structure can realize convenient testing and can help to realize convenient and quick judgment on whether the electrode sheet is damaged.

[0040] In addition, the utility model adopts the method of designing the loop pins as the leftmost and rightmost pins of the FPC cable, and can also verify whether the FPC cable is fully installed in the FPC cable holder by detecting the connectivity of the leftmost and rightmost pins through the device after the FPC is fully inserted, thereby simplifying the test of whether the electrode sheet is installed in place in production; specifically, in the existing design, manual observation or multiple resistance tests from the FPC to the gel are required, while the utility model can simplify this test into a simple loop detection, and if the loop detection is a connection, it is regarded as the electrode sheet being installed in place in the FPC holder.

[0041] The present invention also provides a medical testing device, which adopts the electrode sheet structure that is convenient for testing the integrity of the electrode.
