Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a hemodialysis catheter fixing and protective sleeve device. Background Technology

[0002] Hemodialysis is an important renal replacement therapy for patients with acute and chronic renal failure, requiring the establishment of an extracorporeal circulation pathway through a hemodialysis catheter. The stability and fixation of the hemodialysis catheter directly affect the dialysis effect and safety. Improper fixation can easily lead to catheter displacement, slippage, twisting, or kinking, which not only affects hemodialysis efficiency but may also cause serious complications such as hematoma and infection, bringing great suffering and risks to patients.

[0003] Currently, the commonly used fixation method in clinical practice is to use ordinary tape or dressings to secure the hemodialysis catheters. This method is not secure, and the catheters are prone to displacement when the patient moves their limbs. Secondly, the fixation position is not adjustable, making it difficult to adapt to different patient needs; repeated application and removal of the tape can damage the patient's skin and may cause allergies; it cannot effectively protect and position the catheters, making them susceptible to pressure or twisting; finally, the tightness of the fixation is difficult to control—too tight a fixation affects blood circulation, while too loose a fixation fails. Therefore, there is an urgent need for a new type of hemodialysis catheter fixation and protection sleeve device to solve these problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a hemodialysis catheter fixing and protective sleeve device that effectively and reliably fixes the hemodialysis catheter through a clamping component, preventing its displacement and slippage, while also protecting and positioning the catheter, thereby improving patient comfort and treatment safety.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a hemodialysis catheter fixing and protective sleeve device, including a support plate and a clamping assembly. The support plate is symmetrically fixed with straps at both ends. The straps are used to bind and fix the entire device to the patient's arm or other limb. The support plate is slidably provided with clamping seats above both ends. The clamping assembly is located above the clamping seats and is used to clamp and fix the hemodialysis catheter.

[0006] Furthermore, the clamping seat is arranged in an inverted U-shape. The clamping seat is slidably engaged above the support plate. Two adjusting sliders are fixedly mounted at the lower end of the clamping seat. The two adjusting sliders are symmetrically fixed at both ends of the clamping seat. Adjusting grooves are symmetrically arranged on both sides of the support plate. Adjusting guide rods are provided in the adjusting grooves. The adjusting sliders are slidably disposed in the adjusting grooves. The adjusting guide rods pass through the adjusting sliders. The adjusting sliders move linearly along the adjusting guide rods in the adjusting grooves, thereby allowing the clamping seat to slide smoothly and stably along the length of the support plate to meet the fixing requirements of different spacings.

[0007] Furthermore, the clamping assembly includes multiple sets of clamping fixed plates and clamping movable plates. The multiple sets of clamping fixed plates are fixed above the clamping seat, and the multiple sets of clamping movable plates are slidably disposed above the clamping seat and on one side of the clamping fixed plates. The number of clamping fixed plates and clamping movable plates are correspondingly arranged, and the clamping fixed plates and clamping movable plates form a clamping unit. Multiple pairs of clamping units can simultaneously fix multiple hemodialysis tubes.

[0008] Furthermore, a clamping bracket is fixed above the clamping seat. The lower ends of the clamping fixed plate and the clamping movable plate are both located within the clamping bracket. A clamping screw and a clamping guide rod are provided within the clamping bracket. The clamping screw passes through the clamping fixed plate and is threadedly connected to the clamping movable plate. The clamping guide rod passes through the clamping fixed plate and the clamping movable plate. One end of the clamping screw passes through the clamping bracket. A clamping knob is provided at the end of the clamping screw that passes through the clamping bracket. The clamping knob is rotatably located on the outside of the clamping bracket. Rotating the clamping knob can drive the clamping movable plate to move along the clamping guide rod, thereby cooperating with the clamping fixed plate to clamp or release the hemodialysis tube.

[0009] Furthermore, both the clamping fixed plate and the clamping movable plate have clamping arc grooves on their top walls. The clamping arc grooves on the clamping fixed plate and the clamping arc grooves on the clamping movable plate are symmetrically arranged. A clamping arc plate is fixedly installed in the clamping arc groove. The clamping arc plate is made of medical silicone, which can not only adapt to the shape of the hemodialysis tube, but also flexibly clamp and avoid damage.

[0010] Furthermore, the top wall of the support plate is provided with multiple fixing holes, a fixing connecting plate is fixedly provided on one side of the clamping seat, a fixing screw is provided above the fixing connecting plate, the fixing screw is threaded through the fixing connecting plate, a fixing block is fixedly provided at the lower end of the fixing screw, the fixing block is located below the fixing connecting plate, the fixing block matches the fixing hole, and rotating the fixing screw can make the fixing block engage with the fixing hole, thereby fixing the position of the clamping seat.

[0011] Furthermore, the strap is divided into two sections, with the fixed ends of both sections fixedly connected to the support plate. The movable ends of the two sections are respectively provided with Velcro fasteners and Velcro female fasteners. The support plate is fixed to the patient's body by attaching the Velcro fasteners and Velcro female fasteners.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows:

[0013] 1. By setting a sliding clamping seat and multiple clamping components, the fixing position can be flexibly adjusted to adapt to different lengths of hemodialysis tubes and different fixing position requirements, so as to achieve precise and firm clamping of the hemodialysis tubes and effectively prevent displacement and slippage.

[0014] 2. The clamping arc groove and the clamping arc plate made of silicone material can fit tightly against the outer wall of the hemodialysis tube, which can not only ensure the fixation effect, but also avoid damage to the tube caused by rigid compression. At the same time, the silicone material can reduce the wear between the tube and the clamping parts.

[0015] 3. The clamping component is fixed in position by the clamping seat position locking mechanism, which realizes multi-point stable fixation of the hemodialysis tube, effectively preventing tube displacement and detachment, and reducing the risk of infection and the probability of dialysis interruption.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 and Figure 2As shown, the hemodialysis tubing fixing and protective sleeve device proposed in this solution includes a support plate 1 and a clamping assembly 2. The support plate 1 is symmetrically fixed with straps 3 at both ends, and clamping seats 4 are slidably provided above both ends of the support plate 1. The clamping assembly 2 is located above the clamping seats 4.

[0024] like Figures 1-5 As shown, the clamping seat 4 is arranged in an inverted U-shape. The clamping seat 4 is slidably engaged above the support plate 1. Two adjusting sliders 5 are fixedly mounted on the lower end of the clamping seat 4. The two adjusting sliders 5 are symmetrically fixed at both ends of the clamping seat 4. Adjusting grooves 6 are symmetrically arranged on both sides of the support plate 1. Adjusting guide rods 7 are provided in the adjusting grooves 6. The adjusting sliders 5 are slidably disposed in the adjusting grooves 6. The adjusting guide rods 7 pass through the adjusting sliders 5. The clamping assembly 2 includes multiple sets of clamping fixed plates 8 and clamping movable plates 9. The multiple sets of clamping fixed plates 8 are fixed above the clamping seat 4. The multiple sets of clamping movable plates 9 are slidably disposed above the clamping seat 4 and disposed above the clamping fixed plates 8. On one side, the clamping fixing plate 8 and the clamping movable plate 9 are arranged in corresponding numbers. A clamping bracket 10 is fixed above the clamping seat 4. The lower ends of the clamping fixing plate 8 and the lower ends of the clamping movable plate 9 are both located inside the clamping bracket 10. A clamping screw 11 and a clamping guide rod 12 are provided inside the clamping bracket 10. The clamping screw 11 passes through the clamping fixing plate 8 and is threadedly connected to the clamping movable plate 9. The clamping guide rod 12 passes through the clamping fixing plate 8 and the clamping movable plate 9. One end of the clamping screw 11 passes through the clamping bracket 10. A clamping knob 13 is provided at the end of the clamping screw 11 that passes through the clamping bracket 10. The clamping knob 13 is rotatably located on the outside of the clamping bracket 10.

[0025] like Figures 1-3 As shown, the top wall of the support plate 1 is provided with multiple fixing holes 16, and a fixing connecting plate 17 is fixedly provided on one side of the clamping seat 4. A fixing screw 18 is provided above the fixing connecting plate 17, and the fixing screw 18 is threaded through the fixing connecting plate 17. A fixing block 19 is fixedly provided at the lower end of the fixing screw 18. The fixing block 19 is located below the fixing connecting plate 17 and matches the fixing holes 16.

[0026] The clamping fixing plate 8 and the clamping movable plate 9 are both provided with clamping arc grooves 14 on their top walls. The clamping arc grooves 14 on the clamping fixing plate 8 and the clamping arc grooves 14 on the clamping movable plate 9 are symmetrically arranged. A clamping arc plate 15 is fixedly installed in the clamping arc groove 14. The clamping arc plate 15 is made of medical silicone. The strap 3 is divided into two sections. The fixed ends of the two strap sections 3 are fixedly connected to the support guard plate 1. The movable ends of the two strap sections 3 are respectively provided with Velcro buckles 20 and Velcro female buckles 21.

[0027] In practical use, the support plate 1 is placed under the limb where the hemodialysis catheter needs to be fixed. The limb is wrapped with the strap 3 and secured with Velcro fasteners 20 and 21, and the tightness is adjusted to a suitable level. The clamping seat 4 is moved according to the need for fixing the hemodialysis catheter. The adjusting slider 5 at the lower end of the clamping seat 4 moves linearly along the adjusting guide rod 7 in the adjusting groove 6. After the clamping seat 4 is adjusted to a suitable position, the fixing screw 18 is rotated so that the fixing block 19 at the lower end of the fixing screw 18 engages with the fixing hole 16, thereby fixing the position of the clamping seat 4.

[0028] Place the hemodialysis tube in the clamping assembly 2 above the clamping seat 4. The clamping fixed plate 8 and the clamping movable plate 9 form a clamping unit. Each pair of clamping units can hold one hemodialysis tube. At this time, rotate the clamping knob 13 clockwise to drive the clamping screw 11 to rotate. The rotating clamping screw 11 drives the clamping movable plate 9 to move towards the clamping fixed plate 8 until the clamping arc plate 15 at the upper end of the clamping movable plate 9 and the clamping fixed plate 8 gently and firmly clamps the hemodialysis tube. The clamping arc plate 15 is made of medical silicone, which can adapt to the shape of the hemodialysis tube and can clamp flexibly to avoid damage.

[0029] After treatment, rotate the clamping knob 13 counterclockwise. At this time, the clamping screw 11 will drive the clamping movable plate 9 away from the clamping fixed plate 8, thereby causing the clamping arc plate 15 to loosen the hemodialysis tube. After removing the hemodialysis tube, untie the strap 3 and the device can be removed.
