Example

[0024] Reference Figure 1-Figure 2 A novel electrode clamp for bioelectrical impedance measurement comprises a first clamp plate 1, a second clamp plate 2 and a round rod 6. Round holes 5 are provided on both sides of the first clamp plate 1 and the second clamp plate 2. Two slots connected to the round holes 5 are provided on one side of the second clamp plate 2. The first clamp plate 1 is inserted into the slot so that the round holes 5 on the first clamp plate 1 are aligned with the round holes 5 on the second clamp plate 2. The round rod 6 passes through the round holes 5 on the first clamp plate 1 and the second clamp plate 2 so that the first clamp plate 1 and the second clamp plate 2 rotate around the round rod 6. Two torsion springs 7 are sleeved on the circumferential outer wall of the round rod 6. The two torsion springs 7 are The two ends are respectively fixed to the first splint 1 and the second splint 2, and one side of the first splint 1 and the second splint 2 is provided with an avoidance hole 3. When the first splint 1 and the second splint 2 are clamped on the limbs of the tester, since the first splint 1 and the second splint 2 have the avoidance holes 3, when contacting the tester, the ulnar styloid process on the dorsolateral side of the wrist and the inner and outer malleolus of the ankle joint can be effectively avoided, so that the contact between the electrode and the skin is closer and a sufficiently large contact area is guaranteed. At the same time, the electrode clamp can load the extreme end of the tester's limb as much as possible, so as to ensure that the path through which the excitation current passes is the longest.

[0025] In the utility model, the tops of the first splint 1 and the second splint 2 are both provided with sockets, the tops of the first splint 1 are provided with a connecting wire 4, and the connecting wire 4 is plugged into the socket, and the first splint 1 and the second splint 2 are both provided with return grooves 8 on opposite sides, and return pads 9 are glued in the return grooves 8. The return grooves 8 surround the avoidance holes 3 so that the return grooves 8 form a return shape, and the return pads 9 can increase the comfort of the first splint 1 and the second splint 2 clamped on the patient's limbs.

[0026] Working principle: when the first splint 1 and the second splint 2 are clamped on the limbs of the tester, since the first splint 1 and the second splint 2 are both provided with avoidance holes 3, when contacting the tester, the ulnar styloid process on the dorsolateral side of the wrist and the inner and outer malleolus of the ankle joint can be effectively avoided, so that the contact between the electrode and the skin is closer and a sufficiently large contact area is ensured. At the same time, the electrode clamp can load the farthest end of the tester's limb as much as possible, so as to ensure that the path through which the excitation current passes is the longest, and when the first splint 1 and the second splint 2 rotate with the round rod 6 as the center, the torsion spring 7 will generate torsion, so that the clamping force of the electrode clamp is completely determined by the torsion spring 7, and the tester does not need to perform any operation. Therefore, it can be ensured that the clamping force of the electrode clamp for all testers is basically the same. Example

[0029] Working principle: When the first splint 1 and the second splint 2 are not needed, the first splint 1 and the second splint 2 are in a closed state and inserted into the protective cover 10. At this time, the first magnetic block 12 in the protective cover 10 will be adsorbed with the second magnetic block 14 on the first splint 1 and the second splint 2, so as to fix the protective cover 10, so that the protective cover 10 protects the first splint 1 and the second splint 2, thereby preventing the first splint 1 and the second splint 2 from being damaged by collision with foreign objects.
