Description

Technical Field

[0001] This utility model belongs to the field of medical consumables, and in particular relates to a device to prevent hemodialysis tubing from falling off. Background Technology

[0002] Hemodialysis tubing, also known as hemodialysis tubing, is a specialized medical consumable used in hemodialysis. One end of the tubing is connected to the hemodialysis machine, and the other end is connected to the patient's body, thus enabling the exchange of substances between blood and dialysate. When using hemodialysis tubing, it is also necessary to use an anti-drop device to suspend the tubing from the tubing support or the outer shell of the hemodialysis machine, thereby preventing the tubing from falling off.

[0003] Chinese patent application CN221787833U discloses a device to prevent hemodialysis tubing from falling off in a hemodialysis room. The device includes a fixed frame, a drive gear rotatably connected to the inner wall of the fixed frame, and an arc-shaped rod (first type) fixedly mounted on the outer edge of the drive gear. An auxiliary gear is rotatably connected to the side of the inner wall of the fixed frame, and an arc-shaped rod (second type) fixedly mounted on the outer edge of the auxiliary gear. Through the cooperation of the drive gear and the auxiliary gear, an adjusting wheel drives the drive gear to rotate via a round rod, which in turn drives the auxiliary gear to rotate. This, in turn, moves the arc-shaped rods (first and second types) until they are clamped and limited by the inner walls of the arc-shaped rods (first and second types). At this point, the U-shaped rod is released, and a spring (first type) pushes a sliding rod to move. The sliding rod then causes the inner wall of a clamping plate to be limited by the outer edges of the drive gear and the auxiliary gear, thus ensuring that the arc-shaped rods (first and second types) clamp and limit the hemodialysis tubing.

[0004] The aforementioned anti-drop device for hemodialysis tubing used in hemodialysis room care comprises two gears, each with a fixed, interlocking semi-circular arc-shaped rod. Rotation of the gears causes the two arc-shaped rods to interlock, forming a ring to clamp the hemodialysis tubing. However, during the clamping process, i.e., while manually rotating the gears, the hemodialysis tubing must be manually supported and kept between the two arc-shaped rods to ensure effective clamping. Manually rotating the gears is slow, and the other hand must also be used for support. Holding the hemodialysis tubing requires both hands, making the operation difficult and time-consuming. Furthermore, airbags are fixedly connected to the inner walls of the two curved rods, clamping the tubing. However, once fixed to the inner walls of the curved rods, the airbags cannot be inflated or deflated, meaning the clamping range is fixed. Since hemodialysis tubing models are not fixed, different models require different clamping ranges, easily leading to tubing slippage or flattening. To address these issues, we provide a hemodialysis tubing anti-drop device. Summary of the Invention

[0005] The purpose of this utility model is to provide a hemodialysis tubing anti-drop device. By using clamping components with different inner diameters, it can clamp hemodialysis tubing of different specifications and types.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example 1 Please see Figure 1-4 This utility model is a device to prevent hemodialysis tubing from falling off, including a base frame 1, a top frame 3 and a clamping assembly 4. The hemodialysis tubing can be clamped by the clamping assembly 4 on the opposite side walls of the base frame 1 and the top frame 3. The three sets of clamping assemblies 4 have different inner diameters, which can achieve corresponding clamping effects on different types of hemodialysis tubing.

[0025] Specifically, the bottom of the base frame 1 is provided with a base plate 101, and the upper side wall of the base plate 101 is provided with a tube groove 103. The bottom side wall of the top frame 3 is also provided with a tube groove 103. A clamping component 4 is embedded in the tube groove 103. The clamping component 4 includes an arc plate 401 embedded in the tube groove 103. An airbag cushion 402 is fixedly connected to the arc inner wall of the arc plate 401.

[0026] Furthermore, the left and right ends of the base frame 1 are provided with sliding grooves 102, and sliding plates 2 are slidably connected in the sliding grooves 102. The top ends of the two sliding plates 2 are respectively fixedly connected with metal plates 203 and rotating blocks 205. The metal plates 203 are also attracted to magnetic plates 204. A rotating shaft 205a is inserted through the rotating block 205. The rotating block 205 is rotatably connected to the rotating hole 301 on one end of the top frame 3 through the rotating shaft 205a. The magnetic plate 204 is embedded in the bottom side wall of the other end of the top frame 3.

[0027] The operation process of this embodiment is as follows: During use, due to the rotating shaft 205a, the top frame 3 can rotate around the rotating block 205, thereby opening the upper slot between the base frame 1 and the top frame 3. The hemodialysis tubing can then be placed between the corresponding clamping components 4 according to its diameter. After the hemodialysis tubing is placed, the top frame 3 is rotated in the opposite direction, so that the magnetic plate 204 is attracted to the metal block 203, thereby closing the end slot. When the distance between the base frame 1 and the top frame 3 decreases, the two clamping components 4 move closer to each other, and the two opposing arc plates 401 move closer to each other to form a cylinder. The arc plates 401 are clamped to the hemodialysis tubing through the airbag pad 402, thus clamping the hemodialysis tubing placed between them.

[0028] Example 2 Please see Figure 4-5 Based on embodiment 1, a sliding plate 2 and a pushing component 5 are also provided. The sliding plate 2 can be pushed to move up and down in the base frame 1 by the pushing component 5. A top frame 3 is also installed on the top of the sliding plate 2, thereby achieving the purpose of adjusting the size of the clamping interval between the top frame 3 and the base frame 1.

[0029] Specifically, a wheel groove 104 is provided at the bottom front side of the slide groove 102, and shaft holes 104a are provided on the inner walls of the left and right ends of the wheel groove 104. A rotating groove 105 is provided on the side of the wheel groove 104. The pushing assembly 5 includes a wheel axle 502 fixed on the shaft hole 104a. A gear 501 is rotatably connected to the wheel axle 502. The gear 501 is spaced apart from the inner wall of the wheel groove 104 to allow the gear 501 to rotate freely and reduce friction. An mounting block 503 is installed in the rotating hole 105.

[0030] Furthermore, a groove 206 is provided on the front side wall of the slide plate 2, and a toothed plate 201 is inserted into the groove 206. A fastener 202 is installed on the top of the groove 206. The fastener 202 includes an abutting plate 202a that abuts against the top of the toothed plate 201. The top side wall of the abutting plate 202 is connected to the top side wall of the groove 206 through a spring 202b. A rotating rod 503a is rotatably connected to the mounting block 503, and a locking rod 503 is rotatably sleeved on the rotating rod 503a. A slot 501a is provided on the ridge of the gear 501. The locking rod 503 engages with the slot 501a. The gear 501 also meshes with the toothed plate 201.

[0031] The operation process of this embodiment is as follows: When in use, press your finger on the locking rod 504 and push it upward. At this time, the locking rod 504 can be released from the gear 501. Then press your finger on the gear 501 again and push it to rotate. At this time, since the gear 501 meshes with the toothed plate 201, when the gear 501 rotates, the sliding plate 2 can be pushed up and down in the base frame 1 under the linkage effect of the toothed plate 201. This achieves the effect of adjusting the distance between the base frame 1 and the top frame 3. After the clamping component 4 completes the clamping effect on the hemodialysis tubing, push the locking rod 504 again to make it lock into the slot 501a of the gear 501 again, and complete the positioning of the gear 501.
