The first half clamp 11 is provided with a first clamping portion; the second half clamp 21 is provided with a second clamping portion, and the first half clamp 11 is rotatably connected to the second half clamp 21 to adjust the distance between the first clamping portion and the second clamping portion; the first elastic sheet 12 is provided on the first clamping portion and is located on the inner side of the first half clamp 11, and the two ends of the first elastic sheet 12 are connected to the first half clamp 11; the second elastic sheet 22 is provided on the second half clamp 21. The clamping portion is located on the inner side of the second half clamp 21, and both ends of the second elastic sheet 22 are connected to the second half clamp 21; the electrode sheet 13 is arranged on the inner side of the first elastic sheet 12 or the second elastic sheet 22; the first elastic component is arranged between the first half clamp 11 and the first elastic sheet 12, and is connected to the first half clamp 11 and the first elastic sheet 12, and is used to drive the first elastic sheet 12 to reset when there is no external force; the second elastic component is arranged between the second half clamp 21 and the second elastic sheet 22, and is connected to the second half clamp 21 and the second elastic sheet 22, and is used to drive the second elastic sheet 22 to reset when there is no external force.

[0042] It should be noted that the first elastic sheet 12 and the second elastic sheet 22 are both made of thermoplastic polyester elastomer. The first half clamp 11 and the second half clamp 21 are rotatably connected together and are equipped with a torsion spring or a spring so that the first clamping part and the second clamping part can be clamped on the human body.

[0043] The beneficial effects of the passive heating electrode clamp for medical use provided by the utility model are as follows: compared with the prior art, the passive heating electrode clamp for medical use provided by the utility model is provided with a first elastic sheet 12 and a second elastic sheet 22 on the first half clamp 11 and the second half clamp 21 respectively, and an external force is applied to the first elastic sheet 12 and the second elastic sheet 22 to cause them to deform, and the first elastic sheet 12 and the second elastic sheet 22 are reset and deformed again under the action of the first elastic component and the second elastic component. Before using the electrode clamp, an external force is frequently applied to the first elastic sheet 12 and the second elastic sheet 22 to cause them to deform frequently, thereby generating heat, thereby increasing the temperatures of the first elastic sheet 12, the second elastic sheet 22 and the electrode sheet 13, and improving the comfort of the patient when using it.

[0044] like Figure 1 and Figure 2As shown, in a specific implementation of the passive heating electrode clamp for medical use provided by the embodiment of the utility model, the first elastic component includes a first spring 31, and the first spring 31 is arranged between the first half clamp 11 and the first elastic sheet 12; the second elastic component includes a second spring 42, and the second spring 42 is arranged between the second half clamp 21 and the second elastic sheet 22. The first spring 31 and the second spring 42 respectively lift up the first elastic sheet 12 and the second elastic sheet 22, and the first elastic sheet 12 and the second elastic sheet 22 are manually pressed to deform them, and after the pressing force is reduced, the first elastic sheet 12 and the second elastic sheet 22 are reset and deformed again.

[0045] like Figure 1 and Figure 2 As shown, in a specific implementation of the medical passive heating electrode clamp provided by an embodiment of the utility model, a first fixing sleeve 14 is provided on the outer side of the first clamping portion of the first half clamp 11; the first elastic component also includes a slider 32, the slider 32 is slidably matched with the first fixing sleeve 14, and the first spring 31 is arranged in the first fixing sleeve 14, and one end is connected to the slider 32; when the first elastic sheet 12 is in contact with the first half clamp 11 and the first spring 31 is relaxed, the slider 32 protrudes out of the first fixing sleeve 14.

[0046] It should be noted that when using the electrode clamp, the slider 32 is pressed, the slider 32 pushes out the first spring 31, the first spring 31 lifts the first elastic sheet 12, and then the first elastic sheet 12 is pressed to deform the first elastic sheet 12; in this way, when using the electrode clamp, the first spring 31 is completely placed in the first fixing sleeve 14 and will not push the first elastic sheet 12, thereby avoiding the situation where the first elastic sheet 12 cannot fit well with the human body due to the first spring 31 pushing the first elastic sheet 12.

[0047] like Figure 1 and Figure 2 As shown, in a specific implementation of the medical passive heating electrode clamp provided by an embodiment of the utility model, the first elastic component also includes a first push rod 33 and a first push plate 34, one end of the first push rod 33 is connected to the spring, and the other end is used to push the first elastic sheet 12; the first top plate 34 is arranged at one end of the first push rod 33 facing the first elastic sheet 12, is connected to the first push rod 33, and is used to push the first elastic sheet 12 to increase the contact area with the first elastic sheet 12.

[0048] like Figure 1 and Figure 2 As shown, in a specific implementation of the medical passive heating electrode clamp provided by an embodiment of the utility model, the end surface of the first top plate 34 facing the first elastic sheet 12 is a convex arc structure to facilitate fitting with the first elastic sheet 12 to avoid stress concentration.

[0049] like Figure 1 and Figure 2 As shown, in a specific implementation of the medical passive heating electrode clamp provided by an embodiment of the utility model, a first cavity is opened at one end of the slider 32 facing the first elastic sheet 12, and the first spring 31 is disposed in the first cavity; the first elastic component also includes a first piston 35, which is arranged at one end of the first push rod 33 facing away from the first top plate 34 and slidingly seals with the first cavity; one end of the first spring 31 is connected to the bottom of the first cavity, and the other end is connected to the first piston 35.

[0050] The second elastic component also includes a fixed block 41, a second piston 43 and a second push rod 44. The fixed block 41 is arranged on the outer side of the second clamping part of the second half clamp 21 and is connected to the second half clamp 21. The fixed block 41 is connected to the second half clamp 21, and a second cavity is opened at one end of the fixed block 41 facing the second half clamp 21; the second piston 43 is in sliding and sealing cooperation with the second cavity; the second spring 42 is arranged in the second cavity, one end of which is connected to the bottom of the second cavity, and the other end is connected to the second piston 43; one end of the second push rod 44 is connected to the second piston 43, and the other end is connected to the second elastic sheet 22. When the second elastic sheet 22 is in contact with the second half clamp 21, the second spring 42 is in a stretched state.

[0051] The first cavity is connected to the second cavity through the air duct 50 .

[0052] It should be noted that before using the electrode sheet 13, the slider 32 is pressed to lift the first elastic sheet 12, and the first elastic sheet 12 is pressed to push the first piston 35 and compress the first spring 31, so that the gas in the first cavity enters the second cavity through the air duct 50, and the air pressure in the second cavity increases, and the second piston 43 and the second push rod 44 are lifted, and the second push rod 44 lifts the second elastic sheet 22; at this time, the first elastic sheet 12 is in contact with the first half clamp 11, and the second elastic sheet 22 is lifted.

[0053] The pressure on the first elastic sheet 12 is reduced, the first spring 31 pushes the first piston 35 and lifts the first elastic sheet 12, the gas in the second cavity flows back into the first cavity, the second push rod 44 is pulled back by the second spring 42, and then the second elastic sheet 22 is pulled back; at this time, the first elastic sheet 12 is lifted up, and the second elastic sheet 22 fits with the second half clamp 21.

[0054] In this way, the first elastic sheet 12 and the second elastic sheet 22 can be deformed reciprocatingly at the same time only by reciprocatingly pressing the first elastic sheet 12 , which makes the operation more convenient.

[0055] After repeated reciprocating, the temperature of the first elastic sheet 12 and the second elastic sheet 22 rises to a certain temperature, so that the first elastic sheet 12 fits with the first half clamp 11. At the same time, the slider 32 is released to slide outward, and the first push rod 33 is retracted into the first fixed sleeve 14. At this time, the first elastic sheet 12 and the second elastic sheet 22 fit with the first half clamp 11 and the second half clamp 21 respectively.

[0056] like Figure 1 and Figure 2 As shown, in a specific implementation of the passive heating electrode clamp for medical use provided by the embodiment of the utility model, a baffle 36 is provided on the slider 32, and the baffle 36 is connected to the slider 32. The air guide tube 50 is provided on the side of the baffle 36 facing away from the first half clamp 11, connected to the slider 32, and communicated with the first cavity. The baffle 36 limits the maximum sliding distance of the slider 32, so as to avoid frequent impacts on the connection between the air guide tube 50 and the slider 32.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
