Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] A performance testing fixture for acquisition electrodes is provided for testing the performance of acquisition electrode 1. During testing, one end of the two electrodes to be tested is short-circuited, and the other end of the two electrodes is connected to an ECG electrode electrical performance tester 5, thereby enabling convenient testing.

[0028] refer to Figures 1 to 4 The sampling electrode 1 includes a textile body 13, electrodes, a first terminal 11, and a second terminal 12; multiple electrodes can be provided, for example, four; the textile body 13 is long and strip-shaped, and along its length, a first electrode 1A, a third electrode 1C, a fourth electrode 1D, and a second electrode 1B are arranged sequentially, with the first terminal 11 and the second terminal 12 located in the middle of the textile body 13; each of the four electrodes is connected to two terminals respectively through electronic wires or flexible circuits, etc., and the electronic wires or flexible circuits are placed inside the textile body 13, that is, one end of the electrode is connected to the first terminal 11, and the other end of the electrode is connected to the second terminal 12;

[0029] The first terminal 11 includes a first needle body 11a, a second needle body 11b, a third needle body 11c and a fourth needle body 11d. The four needle bodies are respectively connected to the first electrode 1A, the second electrode 1B, the third electrode 1C and the fourth electrode 1D. The four needle bodies are all located inside the protective shell 110 of the first terminal 11 and do not protrude from the protective shell 110.

[0030] The structure of the second terminal 12 is basically the same as that of the first terminal 11, and the two terminals can be arranged symmetrically.

[0031] The acquisition electrode 1 also includes a strap 14 and a buckle 15, which are respectively located at both ends of the textile body 13 for wearing during electrical stimulation therapy.

[0032] refer to Figure 5 The first tooling connector 2 is configured to connect to the first terminal 11 of the acquisition electrode 1;

[0033] The first tooling connector 2 includes multiple needle tubes, and the multiple needle tubes are set one-to-one with multiple needle bodies;

[0034] Each syringe is equipped with an external connector. Multiple external connectors can be short-circuited together.

[0035] The first tooling connector 2 includes a first needle tube 2a, a second needle tube 2b, a third needle tube 2c, and a fourth needle tube 2d, with the four needle tubes respectively connected to the first needle body 11a, the second needle body 11b, the third needle body 11c, and the fourth needle body 11d.

[0036] The first needle tube 2a is connected to the first external wire 21, the second needle tube 2b is connected to the second external wire 22, the third needle tube 2c is connected to the third external wire 23, and the fourth needle tube 2d is connected to the fourth external wire 24; the four external wires are soldered to the four needle tubes respectively.

[0037] The first tooling connector 2 includes a housing 20, inside which is a needle tube. One end of the needle tube can be connected to the needle body, and the other end of the needle tube is connected to an external wiring device.

[0038] The interior of the housing 20 can accommodate the first terminal 11. When the first tooling connector 2 is connected to the first terminal 11, the housing 20 can cover the first terminal 11.

[0039] refer to Figure 7 and Figure 8 When testing the first electrode 1A and the second electrode 1B, the first tooling connector 2 is connected to the first terminal 11. Then, the first external wiring 21 and the second external wiring 22 can be short-circuited through a clamp 50, a cap, or screwing, thus achieving a short-circuit connection at one end of the first electrode 1A and the second electrode 1B. Then, the first connecting line 51 of the ECG electrode electrical performance tester 5 is directly connected to the first electrode 1A through a clamp 50, and the second connecting line 52 is directly connected to the second electrode 1B through a clamp 50. Then, the five performance tests of the electrodes—impedance, offset, noise, current tolerance, and defibrillation—can be performed. Therefore, the design of the first tooling connector 2 facilitates the short-circuit connection of the two electrodes, improving testing efficiency.

[0040] Similarly, when testing the third electrode 1C and the fourth electrode 1D, the first tooling connector 2 is connected to the first terminal 11. Then, the third external wire 23 and the fourth external wire 24 can be short-circuited by means of clamp 50, electric cap, or screwing, thereby achieving a short-circuit connection at one end of the third electrode 1C and the fourth electrode 1D. Then, the first connecting line 51 of the ECG electrode electrical performance tester 5 is directly connected to the third electrode 1C through clamp 50, etc., and the second connecting line 52 is directly connected to the fourth electrode 1D through clamp 50, etc. Then, the five performance tests of the electrode, namely impedance, offset, noise, current tolerance, and defibrillation, can be performed.

[0041] Optional, see reference Figure 6 The system also includes a second tooling connector 3, which is configured to connect to the second terminal 12. The structure of the second tooling connector 3 is basically the same as that of the first tooling connector 2. The two tooling connectors can be arranged symmetrically. Both the first tooling connector 2 and the second tooling connector 3 are assembled or fixed to the housing 4, meaning the test fixture has two tooling connectors. The second tooling connector 3 can serve as a backup. During measurement, the two electrodes can be short-circuited through the first tooling connector 2 or the second tooling connector 3. In addition, both tooling connectors can be marked to prevent incorrect connection and reduce or avoid connection errors. Of course, the second tooling connector 3 may or may not have external wiring.

[0042] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
