Description

Technical Field

[0001] The invention belongs to the technical field of kidney disease nursing, and in particular relates to a supporting nursing device based on kidney disease hemodialysis. Background Art

[0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. For patients on maintenance hemodialysis, long-term vascular access is usually required in the patient's arm to connect the dialysis tube to draw blood out of the body for dialysis. Vascular access and connecting tubes are crucial for dialysis treatment, so they must be properly protected. Supporting the arm can reduce the movement of the arm and the tube, thereby reducing the risk of damage to the vascular access.

[0003] In the Chinese patent with publication number CN218010237U, a support and nursing device based on hemodialysis for kidney disease is mentioned, which includes an arm support plate, a support rod, and a mounting seat; a fixing strap is provided, and by providing two fixing straps at both ends, after the patient's arm that needs dialysis is placed on the arm support plate, the arm can be fixed by the two fixing straps, and the fixing position will not affect the connection between the dialysis pipeline and the blood vessels in the arm; a clamping plate is provided on both sides of the base in a symmetrical shape, and the clamping degree of the clamping plate to the base can be adjusted by rotating the tightening knob, thereby adjusting the difficulty of the arm support plate when rotating to meet the use needs of different patients; the inner side plate surface of the clamping plate is fixedly connected to a rubber anti-skid pad by gluing, and when the base is fully clamped, the rubber anti-skid pad can have a large friction force on the surface of the base, thereby ensuring the firmness after clamping;

[0021] (1) By setting a movable wheel, a third connecting seat, a second movable plate and a first movable plate, the second movable plate and the first movable plate are pulled to rotate on the outer surface of the connecting column. This rotation will drive the third connecting seat to move, and the third connecting seat will drive the movable wheel to move through the movable interlaced connection. When the two movable wheels are adjusted to a suitable angle, they are firmly fixed by the second connecting block.

The displacement of the extension frame will pull the second connecting plate to move accordingly, thereby driving the first supporting plate to a suitable position. In addition, the sliding of the extension frame will also prompt the second fixing block to move, thereby causing the second supporting plate to move. The movement of the second supporting plate further prompts the second connecting seat to move. The second connecting seat then pulls the displacement block to slide smoothly in the L-shaped bracket. Finally, it is fixed by the fixing column to ensure that the second supporting plate is used for stable and effective support, so that it can be adjusted according to the patient's arm length to better adapt to the user.

[0023] (3) By setting a telescopic rod, an L-shaped bracket, a positioning rod, a limiting hole, a first fixing block, a screw and a fastening nut, the telescopic rod is pulled to slide inside the L-shaped bracket to achieve the purpose of adjusting the height. After adjusting to the required height, the arc plate and the upper part of the supporting structure are firmly supported in a suitable position by the positioning rod. If the angle of the supporting structure needs to be adjusted, its upper part is pulled so that the first fixing block drives the first connecting seat to flexibly rotate on the upper part of the telescopic rod. When it is rotated to a satisfactory angle, it is fixed with a screw and a fastening nut to ensure the accuracy and stability of the angle adjustment, so that it can be flexibly adjusted according to the needs of the patient.

[0048] The stabilizing structure 33 includes a displacement block 331, a second connecting seat 332, a fixing column 333, a second support plate 334, a second fixing block 335 and an extension frame 336. The second connecting seat 332 is fixedly connected to one side of the top end of the displacement block 331. The fixing column 333 is threadedly connected to the middle part of one end of the displacement block 331. Two second support plates 334 are provided, and the two second support plates 334 are movably connected to the two ends of the second connecting seat 332 respectively.

The displacement block 331 is movably connected to the outer surface of the L-shaped bracket 2.

[0049] As can be seen from the above, by pulling the extension frame 336, the extension frame 336 slides on the outer surface of the first connecting plate 31. When the extension frame 336 is displaced, it will drive the second connecting plate 34 fixedly connected thereto to be displaced, and the second connecting plate 34 will drive the first support plate 35 fixedly connected thereto to be displaced, so that the appropriate position can be adjusted according to the user's arm length. When the extension frame 336 is displaced, it will drive the second fixed block 335 fixedly connected thereto to move, and the second fixed block 335 will drive the second support plate 334 movably connected thereto to move, and the second support plate 334 will drive the second connecting seat 332 movably connected thereto to move, and the second connecting seat 332 will pull the displacement block 331 fixedly connected thereto to slide in the L-shaped bracket 2, and then fix it through the fixing column 333, so as to use the second support plate 334 for stable support.

[0050] Preferably, the extension frame 336 is movably connected to the outer surface of the first connecting plate 31, and one end of the second connecting seat 332 away from the second supporting plate 334 is in contact with the outer surface of the L-shaped bracket 2;

[0054] Furthermore, the present invention is designed and applied in a kidney disease nursing support arm. In order to adapt to different use environments, the mounting base 1 needs to be firmly fixed on the bed first, and then the telescopic rod 4 is pulled to slide inside the L-shaped bracket 2 to achieve the purpose of adjusting the height. After adjusting to the required height, the positioning rod 6 is passed through the L-shaped bracket 2 and accurately inserted into the corresponding limiting hole 5, so as to firmly support the arc plate 12 and the upper part of the supporting structure 3 in a suitable position;

[0055] Next, if the angle of the support structure 3 needs to be adjusted, just gently pull its upper part, and this action will drive the first fixing block 13 to move accordingly, and the first fixing block 13 will drive the first connecting seat 7 closely connected thereto to rotate flexibly on the upper part of the telescopic rod 4. When it is rotated to a satisfactory angle, it is fixed with the screw rod 8 and the fastening nut 10 to ensure the accuracy and stability of the angle adjustment;

[0056] Furthermore, in order to meet the arm length requirements of different users, the extension frame 336 can be pulled to make it slide smoothly on the outer surface of the first connecting plate 31, and the displacement of the extension frame 336 will pull the second connecting plate 34 to move accordingly, thereby driving the first support plate 35 to a suitable position. In addition, the sliding of the extension frame 336 will also prompt the second fixed block 335 to move, and the second fixed block 335 will drive the second support plate 334 to move through a movable interlaced connection, and the movement of the second support plate 334 will further prompt the second connecting seat 332 to move, and the second connecting seat 332 will pull the displacement block 331 to slide smoothly in the L-shaped bracket 2, and finally, it is fixed by the fixing column 333 to ensure stable and effective support using the second support plate 334.

[0057] During the dialysis process, in order to prevent the dialysis tube from getting entangled and affecting the dialysis stability, pull the second movable plate 945 and the first movable plate 944 to make them rotate on the outer surface of the connecting column 941. This rotation will drive the third connecting seat 947 fixedly connected thereto to move, and the third connecting seat 947 will drive the movable wheel 946 to move through the movable interlaced connection. When the two movable wheels 946 are adjusted to a suitable angle, they are firmly fixed by the second connecting block 943. At this time, place the dialysis tube in the two movable wheels 946, and the movable wheels 946 will reliably support and limit the dialysis tube, thereby effectively avoiding the entanglement problem and ensuring the smooth progress of the dialysis process.
