[0040] The electrode kit 1 includes an electrochemical test paper 11, a contact plate 12 and a liquid leakage hole 13, the electrochemical test paper 11 adopts a screen-printed electrode or a laser-induced graphene electrode, the electrode is in contact with urine to generate a measurable electrical signal (such as current or voltage); the contact plate 12 is a PCB plate connecting the electrochemical test paper 11 and the electrochemical workstation, which is made of FR-4 and serves as a conductor; the liquid leakage hole 13 is used for urine collection and leads the urine into the electrode kit 1, and the urine is in contact with the electrochemical test paper 11; the liquid leakage hole 13 is arranged at the side of the electrochemical test paper 11, the electrochemical test paper 11 is electrically connected to the contact plate 12, the buffer solution bottle 2 is provided with a buffer solution 21, and the liquid leakage hole 13 can be soaked in the buffer solution 21; when the electrode kit 1 is installed in the buffer solution bottle 2, the buffer solution 21 in the buffer solution bottle 2 enters the electrode kit 1 through the liquid leakage hole 13, the buffer solution 21 is a fixed volume of PBS liquid, and the liquid has been prepared with the required PH value, so that the urine with accurate dilution ratio and accurate PH value can be obtained to meet the detection method using non-enzyme catalyst in biological detection.

[0050] S2: straightly place the electrode kit 1, and wait for the excess urine to drip along the cutter direction until the dripping stops;

[0051] S3: take out the buffer bottle 2, and then insert the electrode kit 1 into the buffer bottle 2 by using the cutting head 14 on the electrode kit 1 to pierce the membrane 22 on the buffer bottle 2, so that the liquid hole 13 is soaked in the buffer 21;

[0052] S4: gently shake the buffer bottle 2 to make the liquid in the electrode kit 1 and the liquid in the buffer bottle 2 fully mixed, and attention should be paid to prevent the liquid from spilling, and assuming that the volume of the buffer 21 in the buffer bottle is L2, then the urine in the electrode kit in the buffer bottle is diluted to L1 / (L1+L2) at last;

[0053] S5: connect the gold fingers 122 of the contact plate 12 at the end of the electrode kit 1 to the electrochemical workstation, load the voltage according to the preset program of the electrochemical workstation, start the experiment, and then analyze the accurate value of the specific component in the urine.
