Description

Technical Field

[0001] This invention relates to the field of hemodialysis technology, specifically to a hemodialysis tubing fixing device that facilitates connection. Background Technology

[0002] A hemodialysis machine consists of two parts: a blood monitoring and alarm system and a dialysate supply system. Its working principle is as follows: Dialysis concentrate and dialysis water are mixed through the dialysate supply system to form a qualified dialysate. This dialysate is then passed through the hemodialyzer and undergoes solute diffusion, osmosis, and ultrafiltration with the patient's blood drawn from the blood monitoring and alarm system. The treated patient blood is then returned to the patient through the blood monitoring and alarm system, while the used dialysis fluid is discharged as waste fluid from the dialysate supply system. This cycle repeats continuously to complete the entire dialysis process.

[0003] Existing hemodialysis tubing fixation devices have limited effectiveness: adhesive tape is easily loosened or detached due to patient sweating, skin oils, or limb movement, failing to provide continuous and reliable fixation, especially for patients requiring long-term treatment. Comfort is also poor: repeated application and removal of adhesive tape can damage the patient's skin, causing pain, allergies, or breakage; tight fixation methods may compress local tissues, affecting blood circulation and leading to numbness and discomfort in the patient's limbs. Therefore, a more easily connectable hemodialysis tubing fixation device is proposed. Summary of the Invention

[0015] (III) Beneficial Effects This invention provides a convenient device for securing hemodialysis tubing. It offers the following advantages: It provides multiple, stable clamping fixation methods: A clamping mechanism consisting of a clamping plate, positioning block, elastic band, and pressure plate, in conjunction with the positioning groove and T-shaped locking rod (spring return) of the support mechanism, achieves a "three-point" stable locking of the hemodialysis tubing (clamping groove, elastic band, pressure plate). This design effectively prevents slippage, displacement, or twisting of the tubing during treatment due to unconscious patient movement or external traction, greatly improving fixation reliability and ensuring the continuity and safety of the treatment process.

[0016] Easy to observe and quick to install / remove: The observation hole at the top of the upper support plate allows medical staff to directly and clearly observe the condition of the tubing below (especially the puncture point or connection) without disassembling any parts, facilitating the timely detection of problems such as bleeding, hematoma, and tubing kinks. Simultaneously, the clamping mechanism, through the interlocking of positioning blocks and slots, combined with the plug-and-play locking of the T-shaped rod, enables the quick installation, positioning, and removal of the clamping plate. This facilitates rapid tubing management or adjustment of its fixation position in emergency situations, improving clinical operational efficiency.

[0017] Significantly improves patient comfort: The liquid-filled bladder pad on the top surface of the lower support plate, together with the internal massage plate and massage head, can provide regular and gentle massage driven by a motor. This helps promote local blood circulation in the immobilized limb, relieving muscle stiffness, numbness, and discomfort caused by prolonged immobilization. The design of the U-shaped tube and the fluid guide tube allows liquid (such as warm water) to circulate within the liquid-filled bladder pad. Combined with the heating wire wrapped around the fluid guide tube, it can provide controlled heat therapy to the patient's limb, further reducing discomfort and enhancing the comfort experience during treatment.

[0020] 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.

[0021] Please see Figure 1-5This invention provides a technical solution: a hemodialysis tubing fixing device for easy connection, comprising a support mechanism and a clamping mechanism 5. The support mechanism consists of an upper support plate 4 and a lower support plate 2, forming a limiting cavity between the upper support plate 4 and the lower support plate 2. An observation hole 7 is provided in the center of the top surface of the upper support plate 4, and positioning grooves 13 are symmetrically provided on both sides of the top surface of the upper support plate 4. A liquid bladder pad 3 is installed on the top surface of the lower support plate 2, and a U-shaped tube 8 is installed on the outer wall of the lower support plate 2. A liquid pump 29 is provided in the middle of the U-shaped tube 8, and fixing plates 1 are installed on both sides of the bottom of the lower support plate 2. By setting up the limiting cavity formed by the upper support plate 4 and the lower support plate 2, and the top structure with the observation hole 7, a stable basic framework is provided for the overall device. The design of the observation hole 7 allows medical staff to directly and clearly monitor the condition of the tubing below (especially the puncture point) without disassembly, facilitating timely detection of bleeding, hematoma, or tubing abnormalities, greatly improving the convenience and safety of clinical observation. The positioning groove 13 provides the foundation for the quick and accurate installation of the clamping mechanism 5. The clamping mechanism 5 is located on the top surface of the upper support plate 4. It includes a clamping plate 17 and a positioning block 21 installed in the center of the bottom surface of the clamping plate 17. The positioning block 21 is embedded in the positioning groove 13, and positioning holes are provided on its side walls. A clamping groove is provided in the center of the top surface of the clamping plate 17, and several anti-slip strips are provided on the inner wall of the clamping groove. Elastic bands 15 are provided on both sides of the top of the clamping plate 17, and a pressure plate 18 is connected to the center of the top surface of the clamping plate 17. The clamping plate 17, positioning block 21, clamping groove, anti-slip strips, elastic bands 15, and pressure plate 18 together constitute a multi-layered and reliable fixing system. The embedded connection between the positioning block 21 and the positioning groove 13 ensures accurate initial alignment and overall stability of the clamping mechanism 5 during installation. The anti-slip strips on the clamping groove and its inner wall can firmly hold and increase the friction with the pipeline, effectively preventing axial sliding. The elastic band 15 provides flexible restraint, which can adapt to different pipe diameters and distribute pressure, while the pressure plate 18 serves as a rigid fixing point. The three work together to achieve "flexible wrapping + rigid locking" of the pipeline, resulting in a firm fixation effect that is not easy to damage the pipeline.

[0022] In a further improvement, a T-shaped rod 32 is movably connected inside the upper support plate 4. The end of the T-shaped rod 32 extends outside the upper support plate 4 and is connected to a pull block 12. A positioning rod 14 is symmetrically arranged at the front end of the T-shaped rod 32. The end of the positioning rod 14 extends into the positioning groove 13 and passes through the positioning hole of the positioning block 21. A spring 31 is installed in the middle of the front end of the T-shaped rod 32, and the end of the spring 31 is fixedly connected to the inner wall of the upper support plate 4. The plug-in locking mechanism composed of the T-shaped rod 32, the positioning rod 14, and the spring 31 is the key to realizing the quick assembly and disassembly of the clamping mechanism 5. By pulling the pull block 12, the positioning rod 14 can be disengaged from the positioning hole of the positioning block 21, thereby unlocking and removing the clamping plate 17; after being released, the spring 31 pushes the T-shaped rod 32 to reset, automatically completing the locking. This design makes the operation extremely quick and convenient when emergency treatment of pipelines or adjustment of position is required, significantly improving nursing efficiency.

[0023] In a further improvement, one end of the elastic band 15 is fixedly connected to the clamping plate 17, and the other end of the elastic band 15 is fixedly connected to a connecting block 22. A protrusion 19 is formed in the middle of the surface of the connecting block 22, and connecting holes 23 are respectively opened on both sides of the surface of the connecting block 22. A groove is opened on one side of the surface of the clamping plate 17, and a connecting rod 20 is fixed inside the groove. The connecting block 22 is embedded in the groove, and the connecting rod 20 passes through the connecting hole 23. Fixing bolts 16 are respectively installed on both sides of the surface of the pressure plate 18, and the ends of the fixing bolts 16 are threadedly connected to the clamping plate 17. The connecting block 22 at the end of the elastic band 15, the groove on the clamping plate 17, and the connecting rod 20 constitute a connection method that can be quickly disassembled. Fixing is completed by embedding the connecting block 22 into the groove and passing the connecting rod 20 through the connecting hole 23.

[0024] In a further improvement, the U-shaped tube 8 is symmetrically equipped with liquid guide tubes 27. One end of the liquid guide tube 27 is connected to the liquid pump 29, and the other end extends into the lower support plate 2 and connects to the liquid bladder pad 3. A heating wire 28 is wound around the outer wall of the liquid guide tube 27. The U-shaped tube 8, liquid pump 29, liquid guide tube 27, and heating wire 28 constitute a closed liquid circulation heating system. The liquid pump 29 drives the liquid (such as warm water) to circulate between the liquid bladder pad 3 and the U-shaped tube 8, while the heating wire 28 wound around the liquid guide tube 27 heats the circulating fluid. This system provides continuous and uniform warmth to the liquid bladder pad 3, which is in contact with the patient's limb, helping to promote local blood circulation and alleviate the coldness and discomfort in the limbs caused by prolonged treatment, especially suitable for patients with poor peripheral circulation.

[0025] Further improvements include a screw 30 internally connected to the lower support plate 2, with an adjusting block 26 threaded onto the screw 30. A massage plate 24 is fixedly connected to the upper end of the adjusting block 26. A motor 10 is mounted at the end of the lower support plate 2, and the power output end of the motor 10 is connected to the screw 30. The massage plate 24 has an arc-shaped structure and a number of massage heads 25 evenly distributed on its surface. The massage plate 24 is located below the liquid bladder pad 3, and the massage heads 25 are in contact with the liquid bladder pad 3. The screw 30, adjusting block 26, motor 10, and the arc-shaped massage plate 24 and massage heads 25, all located inside the lower support plate 2, together achieve an automated massage function. The motor 10 drives the screw 30 to rotate, causing the adjusting block 26 and the massage plate 24 above it to reciprocate, so that the massage heads 25 apply regular pressure to the bottom of the liquid bladder pad 3. This gentle massage can further stimulate the patient's limbs, promote blood flow, effectively relieve muscle stiffness, numbness, and fatigue caused by maintaining a fixed posture for a long time, and greatly improve the comfort of treatment.

[0026] Further improvements include mounting strips 11 on both sides of the bottom of the upper support plate 4, and mounting grooves 6 on both sides of the top surface of the lower support plate 2 for use with the mounting strips. The mounting strips 11 on the bottom of the upper support plate 4 and the mounting grooves 6 on the top surface of the lower support plate 2 are interlocked, making the assembly and separation of the upper and lower support plates 2 very simple, quick, and secure. This modular design facilitates the transportation and storage of the device, and also makes it convenient to clean, disinfect, or maintain each part independently.

[0027] Further improvements include an L-shaped fixing plate 1 with a threaded adjustment handle 9 connected to its surface, and a fixing plate connected to the upper end of the adjustment handle 9. The L-shaped fixing plate 1, the adjustment handle 9, and the fixing plate constitute a powerful and adaptable external fixing module. By attaching the L-shaped plate to supports such as bed rails or IV poles, and tightening the adjustment handle 9, the fixing plate at its end generates a strong clamping force, firmly fixing the entire device in various clinical environments. This design ensures the overall stability of the device during use and allows for flexible adaptation to different installation positions and height requirements.

[0028] Working Principle: Installation and Fixation: First, the entire device is securely clamped to the hospital bed or support using the L-shaped fixing plate 1 at the bottom and the adjusting handle 9. The hemodialysis tubing is placed in the clamping groove of the clamping plate 17, using the anti-slip strips inside the groove to prevent slippage. The hemodialysis tubing is then passed through the observation hole 7 and punctured. Next, the elastic bands 15 on both sides are tightened, and the connecting block 22 is snapped into the groove on the side of the clamping plate 17, achieving initial flexible wrapping and fixation. Then, the pressure plate 18 is placed on top, and the fixing bolts 16 on both sides are tightened to apply final rigid pressure to the tubing, completing multiple locking mechanisms. Observation and Quick Maintenance: Throughout the fixation process, critical parts of the tubing (such as connectors and puncture points) remain below the observation hole 7 on the upper support plate 4, allowing medical staff to visually inspect them at any time. When adjustments or emergency handling of the tubing are needed, simply pull the lever 12 to release the locking of the clamping plate 17 via the T-shaped rod 32 mechanism, quickly removing the entire clamping mechanism 5 (including the tubing). After handling, it can be quickly aligned with the positioning slot 13, reinstalled, and locked. Comfort-enhancing auxiliary treatment: During treatment, the liquid circulation heating system and automatic massage system can be activated. The liquid pump 29 drives the liquid to circulate within the liquid bladder pad 3, and the heating wire 28 heats the liquid, providing continuous warmth to the patient's limbs. Simultaneously, the motor 10 drives the screw 30, causing the massage plate 24 and massage head 25 to apply regular pressure to the liquid bladder pad 3, achieving a gentle massage of the patient's limbs. The dual effects of warmth and massage promote local blood circulation, relieve discomfort, and enhance patient comfort during treatment.

[0029] The present invention comprises: 1. a fixing plate; 2. a lower support plate; 3. a liquid bladder pad; 4. an upper support plate; 5. a clamping mechanism; 6. a mounting groove; 7. an observation hole; 8. a U-shaped tube; 9. an adjusting handle; 10. a motor; 11. a mounting strip; 12. a pull block; 13. a positioning groove; 14. a positioning rod; 15. an elastic band; 16. a fixing bolt; 17. a clamping plate; 18. a pressure plate; 19. a protrusion; 20. a connecting rod; 21. a positioning block; 22. a connecting block; 23. a connecting hole; 24. a massage plate; 25. a massage head; and 26. an adjusting block. 7. Fluid guide tube; 28. Heating wire; 29. ​​Liquid pump; 30. Screw; 31. Spring; 32. T-shaped rod. All components are general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that the existing hemodialysis tubing fixation device has limited fixation effect: the tape is easily loosened and fallen off due to the patient's sweat, skin oil or limb movement, and cannot provide continuous and reliable fixation, especially for patients who need long-term treatment. Poor comfort: Repeated application and tearing of tape can damage the patient's skin, causing pain, allergies, or breakage; tight fixation may compress local tissues, affecting blood circulation and leading to numbness and discomfort in the patient's limbs. This invention, through the combination of the aforementioned components, provides multiple, stable clamping fixations: By setting up a clamping mechanism 5 consisting of a clamping plate 17, a positioning block 21, an elastic band 15, and a pressure plate 18, and cooperating with the positioning groove 13 and T-shaped locking rod (spring 31 returning to its original position) of the support mechanism, a "three-point" stable locking (clamping groove, elastic band 15, pressure plate 18) is achieved for the hemodialysis tubing. This design effectively prevents slippage, displacement, or twisting of the tubing during treatment due to the patient's unconscious movements or external traction, greatly improving fixation reliability and ensuring the continuity and safety of the treatment process. Facilitating observation and rapid disassembly: The observation hole 7 on the top of the upper support plate 4 allows medical staff to directly and clearly observe the condition of the tubing below (especially the puncture point or connection) without disassembling any parts, facilitating the timely detection of problems such as bleeding, hematoma, and tubing creases. Simultaneously, the clamping mechanism 5, through the interlocking of the positioning block 21 and the positioning groove 13, combined with the plug-and-play locking of the T-shaped rod 32, enables the rapid installation, positioning, and disassembly of the clamping plate 17, facilitating quick handling of tubing or adjustment of its fixed position in emergency situations, thus improving clinical operational efficiency. Significantly enhancing patient comfort: The fluid-filled bladder pad 3 on the top surface of the lower support plate 2, in conjunction with the internal massage plate 24 and massage head 25, provides regular, gentle massage driven by the motor 10, helping to promote local blood circulation in the patient's immobilized limb and alleviate muscle stiffness, numbness, and discomfort caused by prolonged immobilization.The design of the U-shaped tube 8 and the fluid guide tube 27 allows liquid (such as warm water) to circulate within the fluid pad 3. Combined with the heating wire 28 wrapped around the fluid guide tube 27, it can provide controlled warm compresses to the patient's limbs, further reducing discomfort and enhancing the comfort experience during treatment.
