Description

Technical Field

[0001] The utility model relates to the technical field of hemodialysis pipelines, and particularly relates to an anti-twist clamp for hemodialysis pipelines. Background Art

[0002] During hemodialysis, the dialysis pipeline needs to be kept unobstructed to ensure the effective exchange of blood and dialysis fluid. Due to patient movement, improper pipeline arrangement or other external factors, the dialysis pipeline often twists or folds. Therefore, an anti-twist clamp for hemodialysis pipelines is needed to fix the pipeline. However, the existing devices still have certain defects in use, such as:

[0003] A kind of hemodialysis pipeline fixing clamp disclosed in the patent number "CN202020896678.3". When this device is in use, it clamps the blood extraction tube and the blood return tube at the same time to prevent the dialysis tube from deflecting. When the device is in use, in the existing dialysis process, the hemodialysis pipeline is directly hung on the dialysis equipment, or the pipeline is fixed to the bedsheet by a vascular clamp. This not only easily causes the hemodialysis pipeline to fall off, but also causes the problem of bending and twisting of the hemodialysis pipeline. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-twist clamp for hemodialysis pipelines to solve the above problems, and improve the problem that the dialysis pipeline of the existing anti-twist clamp for hemodialysis pipelines is prone to fall off.

[0006] The clamping structure includes a clamping base, a clamping block and a friction pad. A clamping base is arranged at the upper end of the fixed base, a clamping block is arranged above the clamping base, and friction pads are arranged on the surfaces of the clamping base and the clamping block.

[0007] Preferably, a clamping block is arranged at the lower end of the fixed base, an installation groove is arranged on the side surface of the mounting seat, and the clamping block is embedded and installed inside the installation groove.

[0008] Preferably, a strong double-sided adhesive is arranged at the lower end of the mounting seat, and two friction blocks are arranged in alignment on the side surface of the clamping block.

[0009] Preferably, a connecting block is arranged at the upper end of the clamping block, and a lifting block is arranged at the upper end of the connecting block.

[0010] Preferably, a fixing block is arranged at the upper end of the lifting block, and a limiting block is arranged at the upper end of the support block.

[0011] Preferably, a limiting rod is provided on the side surface of the limiting block. The limiting rod penetrates through the limiting block and the fixing block. A limiting sleeve is provided on the surface of the limiting rod, and the limiting rod is threadedly connected to the limiting sleeve.

[0012] Preferably, a sliding block is provided inside the supporting block. The sliding block is slidably connected to the supporting block, and a return spring is provided at the upper end of the sliding block.

[0013] Preferably, the lower end of the lifting block is connected to the upper end of the sliding block, and the sliding block penetrates through the supporting block.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. Through the settings of the mounting seat, strong double-sided tape, mounting groove, friction block, clamping block and friction pad, when the device is in use, first, a device is equipped with multiple mounting seats. When the device needs to be installed, the sticker of the strong double-sided tape is torn off, and the mounting seat is fixed on the dialysis equipment through the strong double-sided tape, and it is ensured that the opening of the mounting groove does not face downward. Then, the clamping block below the fixed base is snapped into the inside of the mounting groove, and the friction block is used to increase the friction between the clamping block and the mounting groove, so that the fixed base is more stable when installed on the surface of the mounting seat, thereby fixing the device on the dialysis equipment. Then, the dialysis pipeline is snapped between the clamping block and the clamping base to clamp and fix the dialysis pipeline, so as to prevent the dialysis pipeline from falling off and causing the dialysis pipeline to bend and twist. And the friction pad is used to increase the friction between the dialysis pipeline and the clamping block and the clamping base, so as to prevent the dialysis pipeline from sliding or rotating.

[0025] When the device is in use and it is necessary to clamp the dialysis pipeline, first pull the fixing block 12 to drive the lifting block 11 to move upward, drive the clamping block 9 upward through the lifting block 11, then place the dialysis pipeline on the surface of the clamping base 8, and release the fixing block 12 to make the clamping block 9 fit with the clamping base 8 again, so as to clamp the dialysis pipeline. And by providing two sets of clamping structures 19, the blood extraction pipeline and the blood return pipeline can be clamped and fixed at the same time, improving the stability of the dialysis pipeline. And the friction pads 16 are used to increase the friction force between the pipeline and the clamping base 8 and the clamping block 9 to prevent the dialysis pipeline from sliding and rotating.

[0026] A clamping block 6 is arranged at the lower end of the fixed base 1, and a mounting groove 5 is arranged on the side surface of the mounting seat 2. The clamping block 6 is embedded and installed inside the mounting groove 5;

[0027] When the device is in use, the fixed base 1 is installed on the surface of the mounting seat 2 by sliding the clamping block 6 into the inside of the mounting groove 5.

[0028] The lower end of the mounting base 2 is provided with a strong double-sided adhesive 4, and two friction blocks 7 are arranged on the side of the clamping block 6 in alignment;

[0029] When the device is in use, tear off the sticker on the surface of the strong double-sided adhesive 4, and then fix the mounting base 2 at a position flush with the hospital bed on the surface of the dialysis device through the strong double-sided adhesive 4, preventing the mounting groove 5 from facing downward, and increasing the friction force between the clamping block 6 and the mounting groove 5 through the friction blocks 7, so that the fixed base 1 is more stable when installed on the surface of the mounting base 2.

[0030] The upper end of the clamping block 9 is provided with a connecting block 10, and the upper end of the connecting block 10 is provided with a lifting block 11;
