Description
Technical Field
[0001] This invention belongs to the field of medical device technology, specifically an integrated device for fixing hemodialysis catheters and monitoring infection risk. Background Technology
[0002] Patients with kidney failure have completely lost their kidney's filtration and metabolic functions, making it impossible to properly excrete metabolic waste and regulate electrolyte balance. This leads to a large accumulation of toxins in the body, edema due to fluid retention in the interstitial spaces, and may also be accompanied by acid-base imbalances, severely affecting the body's normal physiological functions. Hemodialysis is often used as an alternative treatment in clinical practice. Patients typically need to go to the hospital for dialysis every other day. Blood purification and metabolism are completed through an external device. During dialysis, the catheter in the vascular access is prone to displacement due to limb movement, which not only affects dialysis efficiency but may also cause damage to the puncture site, increasing the risk of bacterial invasion and infection. Therefore, medical tape is used to firmly fix the catheter to avoid various complications caused by catheter movement. Temperature monitoring of the skin at the connection area between the hemodialysis catheter and the patient is used to assess the patient's infection risk, using changes in the patient's skin temperature to monitor infection risk and prevent the infection from worsening.
[0003] Existing hemodialysis catheter fixation devices are box-shaped structures with an internal S-shaped restraint structure that effectively restricts the catheter and prevents slippage through friction. However, the internal restraint structure requires bending the catheter sequentially to secure it within the restraint structure, which takes a considerable amount of time. Furthermore, the twisting and fixing of the catheter can easily cause pulling on the area where it connects to the patient's body, potentially resulting in secondary injury. Summary of the Invention
[0004] To address the problems mentioned in the background art, the present invention provides an integrated device for hemodialysis catheter fixation and infection risk monitoring. This device solves the problem that existing catheter fixation devices require sequential bending of the catheter to secure it within the restrictive structure, which takes a considerable amount of time. Furthermore, the twisting and twisting of the catheter during fixation can easily cause pulling on the area where the catheter connects to the patient's body, resulting in secondary injury to the patient.

[0008] Preferably, a linkage guide component is provided on the top of the fixed plate at the end away from the adjusting bracket;
[0009] The linkage guide component includes a flip cover, with two sets of flip sleeves installed at the lower end of the flip cover. Limiting shafts are installed on the front and back of the flip cover. Two sets of limiting grooves are opened on the inner side of the lower end of the flip cover. Four sets of limiting guide rails are installed on the inner side of the upper end of the flip cover.
[0010] Preferably, a drive plate is flipped on the outer side of the limiting shaft, and an arc-shaped push plate is rotatably provided on the end of the drive plate away from the limiting shaft. An arc-shaped groove is opened on the side of the arc-shaped push plate near the adjustment frame. The linkage guide assembly includes two sets of limiting guide wheels, and the limiting guide wheels are rotatably provided on the top of the fixed plate. A limiting sleeve is installed on the side of the arc-shaped push plate near the adjustment frame, and the connecting rod is rotatably provided on the inner side of the limiting sleeve.
[0011] Preferably, the top of both sides of the fixed plate is provided with a limiting groove, the arc-shaped push plate is slidably disposed inside the limiting groove, and a positioning sleeve is installed on the top of the fixed plate at the end away from the adjusting bracket.
[0012] Preferably, the flip sleeve is rotatably mounted on the outside of the positioning sleeve via a shaft, a soft rubber plate is installed at the bottom of the fixing plate, and Velcro straps are installed on both sides of the soft rubber plate. A limit bracket is fixedly installed on the top of the fixing plate at the end away from the positioning sleeve, a stabilizing frame is installed on the top of the fixing plate, and the stabilizing guide plate is laterally slidably mounted on the inside of the stabilizing frame.
[0013] Preferably, the fixed gear is rotatably mounted on the inner side of one end of the limiting bracket via a bearing, and two sets of transverse guide plates are installed on the inner side of the fixed plate near the adjusting bracket.
[0014] Preferably, guide grooves are provided on the inner sides of both ends of the adjusting bracket, and the guide grooves are slidably disposed on the outer side of the transverse guide plate.
[0015] Preferably, a pull-out bracket is slidably provided on the inner side of the upper end of the flip cover, and two sets of pull-out guide rods are installed at the bottom of the pull-out bracket. The pull-out guide rods are slidably arranged on the inner side of the limiting groove.
[0016] Preferably, a monitoring instrument is rotatably mounted on the inner side of the upper end of the pull-out bracket, and a display screen is mounted on one side of the monitoring instrument, while a temperature sensor is mounted on the other side of the monitoring instrument. Fixing tape is installed on both sides of the upper end of the pull-out bracket.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] This invention, through the coordinated arrangement of a linkage compression component and a linkage guide component, facilitates the linkage adjustment of the connecting rod and adjustment plate via a flipping mechanism. During adjustment, the adjustment frame is pushed to move laterally. This lateral movement of the adjustment frame, in conjunction with the stabilizing guide plate, drives the fixed toothed frame at the end to move laterally as well. Simultaneously, the inner toothed blocks mesh, causing the fixed gear to rotate 180 degrees along the inner side of the limiting bracket. During this rotation, the first and second eccentric wheels rotate synchronously. The end of the rotating eccentric wheel pushes the adjustment bracket to slide along the lateral guide plate for adjustment. During adjustment, the top adjustment bracket drives the movable anti-slip column towards the fixed anti-slip column. Since the hemodialysis tubing is positioned between the fixed and movable anti-slip columns, the movable anti-slip column, during its movement, compresses the dialysis tubing into a wavy shape. The anti-slip column effectively prevents the hemodialysis tubing from falling off. This linkage adjustment allows for quick installation; simply placing the hemodialysis tubing horizontally inside the device is sufficient for adjustment, eliminating the need for manual bending, thus reducing adjustment time and effectively preventing secondary injury to the patient caused by bending.
[0019] This invention, through the coordination of a linkage guide component and a flip cover, facilitates the lateral sliding adjustment of an arc-shaped push plate along a limiting groove via a flip mechanism. When the flip plate flips along the positioning sleeve, the drive plates on both sides push the arc-shaped push plate to slide along the limiting groove. During installation, the blood catheter is located between the arc-shaped push plate and the limiting guide wheel. As the arc-shaped push plate slides, it pushes the blood catheter to fit tightly against the inner side of the groove of the limiting guide wheel. By sliding, the blood catheter is restricted, keeping it folded towards the patient's head. This effectively reduces the length of the catheter used, thereby lowering costs, and avoids the problem of tangling caused by a long catheter. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] like Figures 1 to 6 As shown, the present invention provides an integrated device for fixing hemodialysis catheters and monitoring infection risk, including a fixing plate 100, and a linkage compression assembly 002 is provided on the top of the fixing plate 100;
[0034] The linkage extrusion assembly 002 includes an adjusting frame 504. A stabilizing guide plate 506 is installed on one side of the adjusting frame 504, and a fixed toothed frame 500 is installed at the end of the stabilizing guide plate 506 away from the adjusting frame 504. A fixed gear 601 is rotatably arranged on the inner side of the fixed toothed frame 500, and two sets of second eccentric wheels 603 are installed at the bottom of the fixed gear 601. First eccentric wheels 602 are arranged at the top and bottom of the second eccentric wheels 603. The linkage extrusion assembly 002 includes two sets of adjusting brackets 600. The adjusting brackets 600 are laterally slidably arranged on the inner side of one end of the fixed plate 100. The first eccentric wheel 602 and the second eccentric wheel 603 are rotatably arranged between the two sets of adjusting brackets 600. Movable anti-slip columns 605 are installed on the top of both ends of the adjusting brackets 600, and six sets of fixed anti-slip columns 105 are installed on the top of the fixed plate 100 near the movable anti-slip column 605.
[0035] The above scheme is adopted: the fixed plate 100 can provide support for the overall structure at the top and provide an installation position for the inner structure. The adjusting frame 504 can restrict the inner structure. When the adjusting frame 504 slides laterally, it can cooperate with the stabilizing guide plate 506 to adjust the position of the fixed toothed frame 500. The stabilizing guide plate 506 can slide laterally along the inner side of the stabilizing frame 108 to effectively ensure the stability of the adjustment. When the fixed toothed frame 500 moves laterally, the toothed block will mesh and drive the fixed gear 601 to rotate. The rotation of the fixed gear 601 and the fixed toothed frame 500 can drive the bottom structure to adjust and achieve the effect of compression. The rotation of the first eccentric wheel 602 and the second eccentric wheel 603 can contact and push the adjusting bracket 600 to slide laterally along the limiting guide rod 505. The adjusting bracket 600 can restrict the structure at the top. During the sliding process of the fixed anti-slip column 105, it can push the dialysis catheter to bend and deform. The fixed anti-slip column 105 can restrict the dialysis catheter. The friction force can effectively prevent the dialysis catheter from falling off and sliding.
[0036] like Figure 4 As shown, two sets of limiting guide rods 505 are installed inside the adjusting frame 504, and an adjusting plate 502 is slidably arranged on the outer side of the limiting guide rods 505. Connecting rods 501 are installed on both sides of the adjusting plate 502. The side of the adjusting plate 502 near the stabilizing guide plate 506 is elastically connected to the adjusting frame 504 through two sets of return springs 503. The return springs 503 are sleeved on the outer side of the limiting guide rods 505.
[0037] Using the above scheme: the limiting guide rod 505 can limit the adjusting plate 502, and the adjusting plate 502 can be synchronously adjusted by the movement of the two sets of connecting rods 501. The connecting rods 501 can rotatably connect the adjusting plate 502 and the limiting sleeve 404, and the reset spring 503 can push the adjusting plate 502 to reset when it is not under force.
[0038] like Figure 5 and Figure 6 A linkage guide component 001 is provided on the top of the end of the fixed plate 100 away from the adjusting bracket 600;
[0039] The linkage guide component 001 includes a flip cover 200, two sets of flip sleeves 201 are installed at the lower end of the flip cover 200, limit shafts 202 are installed on the front and back of the flip cover 200, two sets of limit grooves 203 are opened on the inner side of the lower end of the flip cover 200, and four sets of limit guide rails 204 are installed on the inner side of the upper end of the flip cover 200.
[0040] A drive plate 401 is flipped on the outer side of the limiting shaft 202, and an arc-shaped push plate 402 is rotatably provided on the end of the drive plate 401 away from the limiting shaft 202. An arc-shaped groove 403 is provided on the side of the arc-shaped push plate 402 near the adjusting frame 504. The linkage guide assembly 001 includes two sets of limiting guide wheels 400, and the limiting guide wheels 400 are rotatably provided on the top of the fixed plate 100. A limiting sleeve 404 is installed on the side of the arc-shaped push plate 402 near the adjusting frame 504, and the connecting rod 501 is rotatably provided on the inner side of the limiting sleeve 404.
[0041] The above scheme is adopted: the flip cover 200 can be flipped to adjust the whole device. When the flip cover 200 is closed, it can also protect the inner structure. The flip sleeve 201 can be combined with the positioning sleeve 102 through the shaft. After combination, it can be flipped and adjusted. The limiting shaft 202 can limit the drive plate 401 and assist the drive plate 401 in flipping and adjusting. The limiting groove 203 can limit the inner pull-out guide rod 302. The limiting guide rail 204 can increase the stability of the pull-out bracket 301 in vertical adjustment. The drive plate 401 can drive the arc-shaped push plate 402 at the end to slide along the inner side of the limiting slide groove 101. The limiting sleeve 404 can limit the inner connecting rod 501. The limiting guide wheel 400 can guide the dialysis catheter to avoid direct bending that affects blood flow and normal dialysis.
[0042] like Figure 1 - Figure 3 As shown, a limiting groove 101 is provided on the top of both sides of the fixed plate 100, and the arc-shaped push plate 402 is laterally slidably disposed inside the limiting groove 101. A positioning sleeve 102 is installed on the top of the fixed plate 100 at the end away from the adjusting bracket 600.
[0043] The flip sleeve 201 is rotatably mounted on the outside of the positioning sleeve 102 via a shaft. A soft rubber plate 103 is installed at the bottom of the fixing plate 100, and Velcro straps 104 are installed on both sides of the soft rubber plate 103. A limit bracket 106 is fixedly installed on the top of the fixing plate 100 at the end away from the positioning sleeve 102. A stabilizing frame 108 is installed on the top of the fixing plate 100, and a stabilizing guide plate 506 is laterally slidably mounted on the inside of the stabilizing frame 108.
[0044] The fixed gear 601 is rotatably mounted on the inner side of one end of the limit bracket 106 via a bearing, and two sets of transverse guide plates 107 are installed on the inner side of the fixed plate 100 near the end of the adjusting bracket 600.
[0045] Using the above scheme: the limiting slide 101 can limit the arc-shaped push plate 402, the positioning sleeve 102 can limit the flipping sleeve 201, the soft rubber plate 103 can fit on the patient's skin surface, and can be used with Velcro straps 104 to increase the stability of fixation and increase the comfort of connection. The limiting bracket 106 can limit the fixed gear 601, thereby effectively increasing the rotational stability of the fixed gear 601. The stabilizing frame 108 can limit the stabilizing guide plate 506 to increase the stability of sliding adjustment. The transverse guide plate 107 can limit the adjusting bracket 600.
[0046] like Figure 2 and Figure 6 As shown, guide plate grooves 604 are provided on the inner sides of both ends of the adjusting bracket 600, and the guide plate grooves 604 are slidably disposed on the outer side of the transverse guide plate 107.
[0047] A pull-out bracket 301 is slidably provided on the inner side of the upper end of the flip cover 200, and two sets of pull-out guide rods 302 are installed at the bottom of the pull-out bracket 301. The pull-out guide rods 302 are slidably provided on the inner side of the limiting groove 203.
[0048] A monitor 300 is rotatably mounted on the inner side of the upper end of the pull-out bracket 301, and a display screen 304 is mounted on one side of the monitor 300. A temperature sensor 305 is mounted on the other side of the monitor 300. Fixing tape 303 is installed on both sides of the upper end of the pull-out bracket 301.
[0049] Using the above scheme: the guide plate groove 604 can be combined with the transverse guide plate 107 to ensure the stability of the transverse sliding of the adjustment bracket 600. The position of the upper monitoring instrument 300 can be changed by pulling the bracket 301 up and down along the inner side of the flip cover 200, thereby adapting to the area of the dialysis wound of different patients. The pull guide rod 302 can slide up and down along the inner side of the limiting groove 203. The monitoring instrument 300 can monitor the skin near the patient's wound through the temperature sensor 305. The monitoring instrument 300 can rotate on the inner side of the upper end of the pull bracket 301 to adjust the position of the temperature sensor 305 to fit the patient's skin. The data can be displayed on the display screen 304, and the temperature changes can be indicated to the patient to avoid infection. The model of the temperature sensor 305 is AS6223. The fixing tape 303 can restrict the pull bracket 301 by fixing it to the patient's skin.
[0050] The working principle and usage process of this invention are as follows: After cannulation, medical tape is used to fix the area near the wound. Then, the fixation plate 100 is placed in the patient's forearm area and fixed with Velcro straps 104. The two sets of tubing are placed directly between the fixed anti-slip post 105 and the movable anti-slip post 605, ensuring that the dialysis tubing is positioned between the limiting guide wheel 400 and the arc-shaped push plate 402. Then, the flip cover 200 is grasped and closed along the positioning sleeve 102. During the closing process, the drive plate 401 pushes the arc-shaped push plate 402 to slide and adjust along the inner side of the limiting slide groove 101. During the sliding process, the two sets of connecting rods 501 push the adjusting plate 502 and the adjusting frame 504 to push the stabilizing guide plate 506. The fixed toothed frame 500 moves laterally. During the movement, the fixed gear 601 and the eccentric wheel are rotated by the meshing of the toothed blocks. When rotating, the eccentric wheel will squeeze the adjusting bracket 600 outward. During the outward expansion, the movable anti-slip column 605 at the top extends outward. With the cooperation of the fixed anti-slip column 105, the dialysis tube can be squeezed and bent into an S-shape. The flip cover 200 continues to flip, and the control arc-shaped push plate 402 squeezes the dialysis tube tightly against the side of the limiting guide wheel 400 and bends it. Before it is completely closed, the position of the pull-out bracket 301 is adjusted, and the monitor 300 is rotated to ensure that the temperature sensor 305 can be in close contact with the patient's skin for monitoring. Finally, it is fixed to the patient's skin by the fixing tape 303.
