Description

Technical Field

[0001] This utility model relates to the technical field of hemodialysis tubing fixing clips, specifically a hemodialysis tubing fixing clip. Background Technology

[0002] Hemodialysis is a renal replacement therapy for patients with acute and chronic renal failure. It involves draining blood from the body and passing it through a dialyzer composed of numerous hollow fibers. The blood exchanges substances with an electrolyte solution containing a concentration similar to that in the body through diffusion, ultrafiltration, adsorption, and convection within and outside the hollow fibers. This process removes metabolic waste and excess water, maintains electrolyte and acid-base balance, and then returns the purified blood to the body. The entire process is called hemodialysis. The hemodialysis tubing clamp is a medical auxiliary device. During hemodialysis, many blood tubing connects the patient and the device.

[0003] Chinese patent CN219558252U discloses a hemodialysis tubing fixing clip. This patent discloses a technical solution that prevents the tubing from falling off, solving the problem that existing hemodialysis tubing fixing clips use adhesive tape to fix the tubing. However, the tape cannot be adjusted multiple times, and the tape is easily detached due to sweat on the patient's skin. This can cause the tubing to be pulled when the patient changes position during the procedure, potentially leading to the tubing becoming twisted, folded, or even slipped, thus affecting the dialysis effect.

[0004] When in use, the device can securely clamp the fixation clip to the patient's arm through the action of the U-shaped clamp. However, the size of the fixation clip is fixed, which is not convenient to clamp the fixation frame on the arms of patients with different hand sizes, thus reducing the effectiveness of use. Therefore, a hemodialysis tubing fixation clip is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hemodialysis tubing fixing clip, which has the advantage of convenient adjustment. It solves the problem that while the U-shaped clamp can securely hold the clip on the patient's arm, the fixed size of the clip makes it inconvenient to clamp the clip on the arms of patients with different hand sizes, thus reducing the effectiveness of use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hemodialysis tubing fixing clamp, comprising a hemodialysis tubing fixing clamp body, two positioning plates disposed on the hemodialysis tubing fixing clamp body, and a connecting plate placed at the bottom of the two positioning plates, wherein a retractable damping rod is fixedly installed on one side of each of the two connecting plates opposite to each other.

[0007] Each of the two retractable damping rods has a fixed plate fixedly connected to one of its opposite sides. Each of the two fixed plates has a fixed frame fixedly connected to one of its opposite sides. The inner top and bottom walls of the two fixed frames are rotatably connected by a drive rod with one end penetrating the fixed frame and extending to its outside via bearings. Each of the two adjacent drive rods has a first screw with one end extending into its interior movably connected to one of its opposite sides away from the fixed frame. Each of the four first screws has a movable plate fixedly connected to one of its opposite sides away from the fixed frame. Each of the four movable plates has a clamping plate fixedly connected to one of its opposite sides away from the fixed frame. Each of the four clamping plates has a rubber pad fixedly connected to one of its opposite sides away from the movable plate.

[0008] The two fixed frames are equipped with drive components to drive the drive rod to rotate.

[0009] The hemodialysis tubing clamp body is equipped with a movable component to drive the connecting plate to move.

[0010] Furthermore, the fixing frame is a U-shaped frame, and each of the four drive rods has a first threaded hole on the side away from the fixing frame. The four first screws extend into the interior of the four first threaded holes and are threadedly connected to them. The clamping plate is an arc-shaped plate.

[0011] Furthermore, the drive assembly includes a mounting rod, one end of which is rotatably connected to the side of the fixed frame away from the fixed plate via a bearing, and the other end of which passes through the fixed frame and extends to the fixed plate. A handle is fixedly connected to the side of the mounting rod away from the fixed plate. A driving bevel gear is fixedly installed on the outer peripheral wall of the mounting rod. A driven bevel gear that meshes with the driving bevel gear is fixedly installed on the outer peripheral wall of both drive rods. Slots are provided on the top and bottom surfaces of both fixed plates. A retaining plate with one end extending into the two slots is fixedly connected to the side of each of the two adjacent moving plates away from the clamping plate.

[0012] Furthermore, the mounting rod is rotatably connected to the fixing plate via a bearing, the threads of two adjacent first screws are opposite, the clamping plate is an L-shaped plate, and the clamping plate and the clamping slot are slidably connected.

[0013] Furthermore, the moving component includes two rotating rods, both of which are rotatably connected to the bottom surface of the hemodialysis tubing clamp body via bearings. Each of the two rotating rods has a second screw extending into its bottom surface. Each of the two second screws has a linkage plate fixedly connected to its bottom surface. The two linkage plates are respectively fixedly connected to two connecting plates. Each of the two positioning plates has two connecting slots on its bottom surface, and the two connecting plates extend into the two connecting slots respectively.

[0014] Furthermore, the connecting plate and the connecting groove are slidably connected, and the bottom surfaces of the two rotating rods are provided with second threaded holes. The two second screws extend into the interior of the two second threaded holes and are threadedly connected to them.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This hemodialysis tubing clamp, through the threaded connection between the drive rod and the first screw, drives the relative movement of two adjacent clamping plates, adjusting the distance between the two adjacent clamping plates. This allows for convenient clamping of the hemodialysis tubing clamp body onto the arms of patients with different hand sizes, improving the effectiveness of use. At the same time, through the threaded connection between the rotating rod and the second screw, the connecting plate is moved, allowing for convenient adjustment of the clamping plate height, making it even more convenient and practical.

Retractable damping rods 9 are fixedly installed on the opposite sides of the two connecting plates 8.

[0023] Two retractable damping rods 9 are fixedly connected to fixed plates 10 on opposite sides. Two fixed plates 10 are fixedly connected to fixed frames 2 on opposite sides. The inner top and bottom walls of the two fixed frames 2 are rotatably connected by bearings to a drive rod 15 that passes through the fixed frame 2 and extends to its outside. Two adjacent drive rods 15 are movably connected to a first screw 14 that extends into its interior on the side away from the fixed frame 2. Four first screws 14 are fixedly connected to a movable plate 11 on the side away from the fixed frame 2. Four movable plates 11 are fixedly connected to a clamping plate 12 on the side away from the fixed frame 2. Four clamping plates 12 are fixedly connected to a rubber pad 13 on the side away from the movable plate 11.

[0024] The fixed frame 2 is a U-shaped frame, and the four drive rods 15 are provided with first threaded holes on the side away from the fixed frame 2. The four first screws 14 extend into the interior of the four first threaded holes and are threadedly connected to them. The clamping plate 12 is an arc-shaped plate.

[0025] It should be noted that the hemodialysis tubing clamp body 1 and the retractable damping rod 9 are both conventional devices known to the public in the prior art, and their specific structures and working principles will not be described in detail in this article.

[0026] Specifically, the drive rod 15 rotates, and through the threaded connection between the drive rod 15 and the first screw 14, the first screw 14 drives the clamping plate 12 to move, thereby pushing the fixing frame 2. Under the action of the telescopic damping rod 9, the fixing frame 2 moves, and the arm is placed between the four clamping plates 12. The fixing frame 2 is released, and the clamping plates 12 are reset. The clamping plates 12 and the arm fit together, clamping the hemodialysis tubing fixing clamp body 1 on the arm. The arm is protected by the rubber pad 13.

[0027] In this embodiment, two fixed frames 2 are equipped with drive components, each including a mounting rod 20. One end of the mounting rod 20 is rotatably connected to the side of the fixed frame 2 away from the fixed plate 10 via a bearing, and the other end passes through the fixed frame 2 and extends to the fixed plate 10. A handle 21 is fixedly connected to the side of the mounting rod 20 away from the fixed plate 10. An active bevel gear 19 is fixedly installed on the outer peripheral wall of the mounting rod 20. A driven bevel gear 18 that meshes with the active bevel gear 19 is fixedly installed on the outer peripheral wall of each of the two drive rods 15. Slots 17 are provided on the top and bottom surfaces of the two fixed plates 10. A clamping plate 16 with one end extending into the two slots 17 is fixedly connected to the side of each of the two adjacent moving plates 11 away from the clamping plate 12.

[0028] The mounting rod 20 is rotatably connected to the fixing plate 10 via a bearing, the threads of the two adjacent first screws 14 are opposite, the clamping plate 16 is an L-shaped plate, and the clamping plate 16 and the clamping groove 17 are slidably connected.

[0029] Specifically, rotating the handle 21 causes the mounting rod 20 to rotate, which in turn drives the active bevel gear 19 to rotate. Through the meshing between the active bevel gear 19 and the driven bevel gear 18, the drive rod 15 is driven to rotate. Through the sliding connection between the clamping plate 16 and the clamping groove 17, the clamping plate 12 is supported, thereby improving the stability of the clamping plate 12.

[0030] In this embodiment, the hemodialysis tubing clamp body 1 is equipped with a movable component.

[0031] The device includes two rotating rods 4, both of which are rotatably connected to the bottom surface of the hemodialysis tubing clamp body 1 via bearings. Each of the two rotating rods 4 has a second screw 6 extending into its bottom surface. Each of the two second screws 6 has a linkage plate 7 fixedly connected to its bottom surface. Each linkage plate 7 is fixedly connected to two connecting plates 8. Each of the two positioning plates 3 has two connecting slots 5 on its bottom surface, and each of the two connecting plates 8 extends into the two connecting slots 5.

[0032] The connecting plate 8 and the connecting groove 5 are slidably connected. The bottom surfaces of the two rotating rods 4 are provided with second threaded holes. The two second screws 6 extend into the interior of the two second threaded holes and are threadedly connected to them.

[0033] Specifically, rotating the rotating rod 4 causes it to rotate. Through the threaded connection between the rotating rod 4 and the second screw 6, and the sliding connection between the connecting plate 8 and the connecting groove 5, the second screw 6 drives the connecting plate 8 to move downward through the linkage plate 7, thereby adjusting the height of the fixing frame 2.

[0034] The working principle of the above embodiments is as follows:

[0035] Rotate the rotating rod 4 to make it rotate. Through the threaded connection between the rotating rod 4 and the second screw 6, and the sliding connection between the connecting plate 8 and the connecting groove 5, the second screw 6 drives the connecting plate 8 to move downward through the linkage plate 7, adjusting the height of the fixing frame 2. After adjustment, rotate the handle 21 to make the mounting rod 20 rotate, thereby driving the active bevel gear 19 to rotate. Through the meshing between the active bevel gear 19 and the driven bevel gear 18, the drive rod 15 is driven to rotate. Through the threaded connection between the drive rod 15 and the first screw 14, and the sliding connection between the clamping plate 16 and the clamping groove 17, the first screw 14 drives the clamping plate 12 to move, thereby pushing the fixing frame 2. Under the action of the telescopic damping rod 9, the fixing frame 2 is moved, the arm is placed between the four clamping plates 12, the fixing frame 2 is released, the clamping plates 12 are reset, the clamping plates 12 and the arm are in contact, and the hemodialysis tubing fixing clamp body 1 is fixed. It is clamped on the arm and protected by the rubber pad 13.
