Description

Technical Field

[0001] This invention relates to the field of nursing kit technology, specifically to a biomedical hemodialysis arteriovenous fistula nursing kit with infection prevention and monitoring capabilities. Background Technology

[0002] Hemodialysis patients rely on arteriovenous fistulas as a long-term vascular access, but the incidence of complications such as infection, stenosis, thrombosis, and aneurysm remains high. This not only directly threatens the safety of patients' treatment and their quality of life, but also increases the medical burden and social costs due to repeated interventions and prolonged hospitalizations.

[0003] Patent CN219230930U discloses a nursing device for arteriovenous fistulas (AVFs) in nephrology dialysis, including an AVF care unit. The AVF care unit mainly consists of two main structures: a limb placement base and an anti-dislodgement heating mechanism. The limb placement base and the anti-dislodgement heating mechanism are integrated together. Two anti-dislodgement heating mechanisms are symmetrically arranged on both sides above the limb placement base, which has a U-shaped structure. This invention can maximize the heating of blood returning to the body, fundamentally reducing discomfort upon blood entry and minimizing temperature differences between blood vessels. Furthermore, friction can prevent the arteriovenous dialysis catheter from being pulled out, improving overall treatment safety. However, this device is susceptible to bacterial infection during use, potentially leading to wound infection during dialysis treatment. Therefore, a biomedical hemodialysis AVF care kit with infection monitoring is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, comprising a dialysis machine body, a fixing block fixedly connected to the left side of the dialysis machine body, a fixing platform rotatably connected to the inner wall of the fixing block, a U-shaped shell fixedly connected to the left side of the dialysis machine body, a hinge plate rotatably connected to the bottom of the fixing platform, a hinge block rotatably connected to the inner wall of the hinge plate, a sliding connection between the left side of the dialysis machine body and the hinge block, and a fixing plate fixedly connected to the top of the fixing platform, with a limit frame provided on the top of the fixing plate. A sterilization tank is fixedly connected to the rear of the U-shaped shell, a spray plate is fixedly connected to the inner wall of the U-shaped shell, a straight plate is fixedly connected to the left side of the hinge block, an elastic rod is slidably connected to the inner wall of the straight plate via a spring, an inclined plate is fixedly connected to the right side of the elastic rod, a baffle is fixedly connected to the left side of the dialysis machine body, a fixing frame is fixedly connected to the inner wall of the U-shaped shell, a long strip plate is slidably connected to the circumferential surface of the fixing frame, an L-shaped plate is fixedly connected to the front of the long strip plate, a massage mechanism for improving blood circulation and preventing thrombosis is provided at the top of the limiting frame, and the fixing platform... The top is equipped with a storage mechanism for storing nursing kits. When hemodialysis treatment is required, the mounting table can be unfolded to ensure that the kits on top of the mounting table are kept away from non-sterile surfaces such as tabletops, reducing the contact area with contaminants and lowering the risk of contamination of sterile items due to improper placement. This helps maintain the core requirements of infection prevention care. The mechanism can also limit and fix the position of the mounting table when it is in a horizontal state, ensuring its stability. The right side of the hinge plate is rotatably connected to the inner wall of the hinge block. The disinfection tank and spray plate are fixed by hoses and a water pump. The inclined plate is connected to the top of the baffle, the front of the spray plate is in contact with the rear of the long plate, the left side of the dialysis machine body is in contact with the right side of the inclined plate, and the right side of the L-shaped plate is in contact with the left side of the hinge block. When the treatment is completed and the staff is putting the machine away, the water pump starts and sprays the disinfectant stored inside the fixed frame into the U-shaped shell. This disinfects the nursing kit stored inside the U-shaped shell, preventing cross-infection caused by contamination of the kit during subsequent operation by medical staff or reuse by patients, and ensuring user safety.

[0006] Preferably, the massage mechanism includes a chamfered plate, which is fixedly connected to the inner wall of a fixed plate. A second elastic rod is slidably connected to the inner wall of the chamfered plate via a spring. A diagonal plate is fixedly connected to the rear of the second elastic rod. A rotating shaft is rotatably connected to the inner wall of the limiting frame. A cam is fixedly connected to the circumferential surface of the rotating shaft. A fixed rod is fixedly connected to the inner wall of the limiting frame via a spring. A force-bearing plate is slidably connected to the circumferential surface of the fixed rod. An elastic telescopic rod is fixedly connected to the bottom of the force-bearing plate. When the fixed platform is unfolded, the patient's arm is placed inside the limiting frame, thereby limiting the patient's arm and preventing unconscious movements such as turning over or raising the arm from causing force, traction, or collision at the fistula puncture site. This reduces the risk of needle displacement and dislodgement, and prevents... In case of arteriovenous fistula injury or bleeding, this device ensures a stable dialysis access and, after nursing care, can fix the position of the limiting frame for easy storage and subsequent disinfection by medical staff. The top of the limiting frame contacts the bottom of the inclined plate, and the top of the force plate contacts the surface of the cam. A motor is installed at the rear of the rotating shaft, which is driven to rotate. The elastic telescopic rod is used to press on the patient's arm. During dialysis, gentle pressure is applied to the arm to produce a massage effect, thereby accelerating blood flow in the arm and surrounding tissues of the fistula, improving local microcirculation, reducing blood stasis, lowering the risk of thrombosis caused by slow blood flow, and providing sufficient blood oxygen to the fistula to help maintain vascular elasticity.

[0007] Preferably, the storage mechanism includes a connecting rod, which is fixedly connected to the front of the limiting frame. A T-shaped plate is slidably connected to the circumferential surface of the connecting rod, and an arc-shaped plate is fixedly connected to the bottom of the T-shaped plate. A connecting rod is rotatably connected to the front of the limiting frame via a torsion spring. A short plate is fixedly connected to the circumferential surface of the connecting rod, and a slapping plate is fixedly connected to the circumferential surface of the connecting rod. A storage box is fixedly connected to the top of the fixed platform, and an elastic rod three is fixedly connected to the bottom of the fixed platform via a spring. A pressure plate is slidably connected to the circumferential surface of the elastic rod three. During the massage of the patient's arm, the slapping plate rotates, providing localized massage to the side of the patient's arm. Tapping stimulates local tissue activity through external force, accelerating blood flow to the extremities and around the fistula, further reducing the time blood remains in the blood vessels, thereby lowering the risk of thrombosis caused by slow blood flow and helping to maintain the patency of the fistula. The bottom of the limiting frame is in contact with the top of the pressure plate, the inner wall of the storage box is in contact with the surface of the pressure plate, the inner wall of the fixing platform is slidably connected to the surface of the pressure plate, and the top of the T-shaped plate is in contact with the bottom of the force plate. When the limiting frame is removed, it can improve the stability of the nursing kit during storage and effectively prevent it from falling off during the disinfection process.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, through the coordinated operation of the dialysis machine body, fixing block, fixing platform, U-shaped shell, hinge plate, hinge block, fixing plate, limiting frame, disinfection tank, spray plate, straight plate, elastic rod, inclined plate, baffle, fixing frame, long strip plate, and L-shaped plate, allows the fixing platform to unfold when a patient needs hemodialysis treatment. This ensures that the kit on top of the fixing platform is kept away from non-sterile surfaces such as the tabletop, reducing the contact area with contaminants and lowering the risk of contamination of sterile items due to improper placement. It helps maintain the core requirements of infection prevention care. When the fixing platform is in a horizontal position, it can limit and fix the position of the fixing platform to ensure its stability. After the treatment is completed and the staff is storing the kit, the water pump starts and sprays the disinfectant stored inside the fixing frame into the U-shaped shell, thereby sterilizing and disinfecting the care kit stored inside the U-shaped shell. This prevents cross-infection caused by kit contamination during subsequent operations by medical staff or patients, ensuring user safety.

[0009] 2. This infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, through the coordinated operation of the chamfered plate, elastic rod II, and inclined plate, places the patient's arm inside the limiting frame when the fixation table is unfolded. This limits the patient's arm, preventing stress, traction, or collision at the fistula puncture site caused by unconscious movements such as turning over or raising the arm. It reduces the risk of needle displacement or dislodgement, prevents damage or bleeding to the fistula vessels, and ensures a stable dialysis access. After the care is completed, the limiting frame can be fixed in position, facilitating storage and subsequent disinfection by medical staff.

[0010] 3. This infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, through the coordinated operation of the rotating shaft, cam, fixing rod, force plate, and elastic telescopic rod, will gently press on the arm during dialysis, producing a massage effect, thereby accelerating blood flow in the arm and surrounding fistula tissues, improving local microcirculation, reducing blood stasis, reducing the risk of thrombosis caused by slow blood flow, and providing sufficient blood oxygen to the fistula blood vessels to help maintain vascular elasticity.

[0011] 4. This infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, through the coordinated operation of connecting rods, T-shaped plates, arc-shaped plates, connecting rods, short plates, and tapping plates, massages the patient's arm while the tapping plates rotate to tap the side of the patient's arm. This external force stimulates local tissue activity, accelerates blood flow to the extremities and around the fistula, further reduces the time blood remains in the blood vessels, thereby reducing the risk of thrombosis caused by slow blood flow and helping to maintain the patency of the fistula.

[0012] 5. This infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, through the coordinated operation of the storage box, elastic rod, and pressure plate, and the removal of the limiting frame, can improve the stability of the care kit during storage and effectively prevent it from falling off during the disinfection process.

[0015] 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.

[0016] Please see Figures 1-8 One embodiment of the present invention is: an infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit, comprising a dialysis machine body 1, a fixing block 2 fixedly connected to the left side of the dialysis machine body 1, a fixing platform 3 rotatably connected to the inner wall of the fixing block 2, a U-shaped shell 4 fixedly connected to the left side of the dialysis machine body 1, a hinge plate 5 rotatably connected to the bottom of the fixing platform 3, a hinge block 6 rotatably connected to the inner wall of the hinge plate 5, the left side of the dialysis machine body 1 being slidably connected to the hinge block 6, a fixing plate 7 fixedly connected to the top of the fixing platform 3, a limit frame 8 provided on the top of the fixing plate 7, and a sterilization tank 9 fixedly connected to the rear of the U-shaped shell 4. A spray plate 10 is fixedly connected to the inner wall of the dialysis machine 4. A straight plate 11 is fixedly connected to the left side of the hinge block 6. An elastic rod 12 is slidably connected to the inner wall of the straight plate 11 via a spring. An inclined plate 13 is fixedly connected to the right side of the elastic rod 12. A baffle 14 is fixedly connected to the left side of the dialysis machine body 1. A fixing frame 15 is fixedly connected to the inner wall of the U-shaped shell 4. A long strip plate 16 is slidably connected to the circumferential surface of the fixing frame 15. An L-shaped plate 17 is fixedly connected to the front of the long strip plate 16. A massage mechanism 18 for improving blood circulation and preventing thrombosis is provided at the top of the limiting frame 8. A storage mechanism 19 for storing the nursing kit is provided at the top of the fixing platform 3. When a patient needs hemodialysis treatment, the dialysis machine body 1 is pushed to the designated position. At this time, the operator opens the movable door on the left side of the U-shaped shell 4 and pushes the straight plate 11 upwards. The upward movement of the straight plate 11 causes the hinge block 6 to move upwards. Simultaneously, the upward movement of the hinge block 6 exerts a squeezing force on the hinge plate 5, forcing it to rotate. The rotation of the hinge plate 5 pushes the fixed platform 3 to rotate, which in turn causes the fixed plate 7 to rotate. The rotation of the fixed plate 7 then causes the limiting frame 8 to rotate, allowing the fixed platform 3 to unfold. This ensures that the components mounted on the top of the fixed platform 3 are kept away from non-sterile surfaces such as tabletops, reducing the contact area with contaminants and lowering the risk of infection. To mitigate the risk of contamination of sterile items due to improper placement and to support the core needs of infection prevention care, the straight plate 11 moves upward, which in turn moves the elastic rod 12 upward. The upward movement of the elastic rod 12 in turn moves the inclined plate 13 upward. The inclined plate 13 moves upward and comes into contact with the inclined surface of the baffle 14. Through the squeezing force, the inclined plate 13 is forced to move to the left. The movement of the inclined plate 13 in turn moves the elastic rod 12 to the left and stretches the spring on the surface of the elastic rod 12. When the inclined plate 13 passes the baffle 14, the inclined plate 13 can move to the right through the spring. This allows the fixed platform 3 to be limited and fixed in position when it is in a horizontal state, ensuring the stability of the fixed platform 3. The right side of the hinge plate 5 is rotatably connected to the inner wall of the hinge block 6. The disinfection tank 9 and the spray plate 10 are fixedly connected through a hose and a water pump. The bottom of the inclined plate 13 is in contact with the top of the baffle 14. The front part of the spray plate 10 is in contact with the rear part of the long strip plate 16. The left side of the dialysis machine body 1 is in contact with the right side of the inclined plate 13. The right side of the L-shaped plate 17 is in contact with the left side of the hinge block 6. When staff are packing up after treatment, they pull the elastic rod 12 outward to displace the inclined plate 13 and the baffle 14, thus releasing the support for the fixed platform 3. This allows the fixed platform 3 to rotate and be inside the U-shaped shell 4. At this time, the hinge block 6 moves downward and contacts the L-shaped plate 17. Through the squeezing force, the L-shaped plate 17 moves to the left. The leftward movement of the L-shaped plate 17 causes the long strip plate 16 to move. The movement of the long strip plate 16 releases the obstruction at the front of the spray plate 10. At this time, the water pump starts and sprays the disinfectant stored inside the fixed frame 15 into the interior of the U-shaped shell 4. This sterilizes and disinfects the nursing kits stored inside the U-shaped shell 4, preventing cross-infection caused by contamination of the kits during subsequent operations by medical staff or reuse by patients, and ensuring user safety.

[0017] Working principle: When a patient needs hemodialysis treatment, the dialysis machine body 1 is pushed to the designated position. At this time, the staff opens the movable door on the left side of the U-shaped shell 4 to ensure that the kit on the top of the fixed platform 3 is away from non-sterile surfaces such as the desktop, reducing the contact area with contaminants and lowering the risk of contamination of sterile items due to improper placement. When the treatment is completed and the staff is storing the equipment, the staff pulls the elastic rod 12 outward to misalign the inclined plate 13 and the baffle 14, thereby releasing the support of the fixed platform 3 and allowing the fixed platform 3 to rotate inside the U-shaped shell 4. At this time, the hinge block 6 moves downward, thereby sterilizing and disinfecting the nursing kit stored inside the U-shaped shell 4, avoiding cross-infection caused by kit contamination during subsequent operation by medical staff or reuse by patients, and ensuring user safety.

[0018] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention: the massage mechanism 18 includes a chamfered plate 181, the chamfered plate 181 is fixedly connected to the inner wall of the fixed plate 7, the inner wall of the chamfered plate 181 is slidably connected to an elastic rod 182 by a spring, the rear part of the elastic rod 182 is fixedly connected to an inclined plate 183, the inner wall of the limiting frame 8 is rotatably connected to a rotating shaft 184, the circumferential surface of the rotating shaft 184 is fixedly connected to a cam 185, the inner wall of the limiting frame 8 is fixedly connected to a fixed rod 186 by a spring, the circumferential surface of the fixed rod 186 is slidably connected to a force plate 187, and the bottom of the force plate 187 is fixedly connected to an elastic telescopic rod 188; When the fixed platform 3 is unfolded, its rotation causes the fixed plate 7 to rotate, which in turn causes the chamfered plate 181 to rotate. At this time, medical staff will pull the elastic rod 182, which moves forward and causes the inclined plate 183 to move forward. The movement of the inclined plate 183 releases the restriction on the limiting frame 8. At this time, medical staff can remove the limiting frame 8 and place it beside the patient's bed. Then, the patient's arm can be placed inside the limiting frame 8, thereby limiting the patient's arm to a certain extent and avoiding... To prevent unconscious movements such as turning over or raising the hand from causing stress, traction, or collision at the fistula puncture site, reduce the risk of needle displacement or dislodgement, prevent fistula vessel damage or bleeding, and ensure the stability of the dialysis access. After nursing care, the position of the limiting frame 8 is aligned with the inclined plate 183. At this time, the chamfered plate 181 will move downward and contact the inclined plate 183, and exert a squeezing force on the inclined plate 183, forcing the inclined plate 183 to move forward, thereby fixing the position of the limiting frame 8, which is convenient for medical staff to store and disinfect. The top of the limiting frame 8 is in contact with the bottom of the inclined plate 183, the top of the force plate 187 is in contact with the surface of the cam 185, a motor is provided at the rear of the rotating shaft 184, and the rotating shaft 184 will be driven by the motor to rotate, and the elastic telescopic rod 188 will be used to press on the patient's arm. During dialysis, the motor starts and drives the rotating shaft 184 to rotate. The rotation of the rotating shaft 184 drives the cam 185 to rotate. During the rotation of the cam 185, it comes into contact with the force plate 187 and exerts a squeezing force on the force plate 187, causing the force plate 187 to move downward. During the downward movement of the force plate 187, it compresses the spring on the surface of the fixing rod 186. The downward movement of the force plate 187 drives the elastic telescopic rod 188 to move downward. During the downward movement of the elastic telescopic rod 188, it comes into contact with the patient's arm and applies slight pressure to the arm, producing a massage effect. This can accelerate blood flow in the arm and the tissues around the fistula, improve local microcirculation, reduce blood stasis, reduce the risk of thrombosis caused by slow blood flow, and at the same time provide sufficient blood oxygen to the fistula blood vessels, helping to maintain vascular elasticity.

[0019] Working principle: When the fixed platform 3 is unfolded, its rotation drives the fixed plate 7 to rotate, which in turn drives the chamfered plate 181 to rotate. At this time, medical staff can remove the limiting frame 8 and place it next to the patient's bed. Then, the patient's arm is placed inside the limiting frame 8, which can limit the patient's arm to a certain extent, preventing the patient from turning over due to unconscious movements. The limiting frame 8 can be fixed in position, making it easy for medical staff to store and disinfect it. During dialysis, as the elastic telescopic rod 188 moves downward, it will come into contact with the patient's arm and apply slight pressure to the arm, producing a massage effect, which can accelerate blood flow in the arm and the tissues around the fistula.

[0020] The storage mechanism 19 includes a connecting rod 191, which is fixedly connected to the front of the limiting frame 8. A T-shaped plate 192 is slidably connected to the circumferential surface of the connecting rod 191. An arc-shaped plate 193 is fixedly connected to the bottom of the T-shaped plate 192. A connecting rod 194 is rotatably connected to the front of the limiting frame 8 via a torsion spring. A short plate 195 is fixedly connected to the circumferential surface of the connecting rod 194. A clapping plate 196 is fixedly connected to the circumferential surface of the connecting rod 194. A storage box 197 is fixedly connected to the top of the fixed platform 3. An elastic rod 198 is fixedly connected to the bottom of the fixed platform 3 via a spring. A pressure plate 199 is slidably connected to the circumferential surface of the elastic rod 198. During the massage of the patient's arm, the downward movement of the force plate 187 pushes the T-shaped plate 192 downward, which in turn drives the arc plate 193 downward. As the arc plate 193 moves downward, it pushes the short plate 195 to rotate. The rotation of the short plate 195 drives the connecting rod 194 to rotate, which in turn drives the patting plate 196 to rotate. As the patting plate 196 rotates, it taps the side of the patient's arm, thereby stimulating local tissue activity through external force, accelerating blood flow in the extremities and around the fistula, further reducing the time blood stagnates in the blood vessels, thus reducing the risk of thrombosis caused by slow blood flow, and helping to maintain the patency of the fistula. The bottom of the limiting frame 8 is in contact with the top of the pressure plate 199, the inner wall of the storage box 197 is in contact with the surface of the pressure plate 199, the inner wall of the fixing platform 3 is slidably connected to the surface of the pressure plate 199, and the top of the T-shaped plate 192 is in contact with the bottom of the force plate 187. During the removal of the limiting frame 8, the limiting frame 8 will release the pressure on the pressure plate 199. At this time, the spring on the surface of the elastic rod 198 will contract and drive the pressure plate 199 to move upward, thereby releasing the pressure on the care kit inside the storage box 197. The squeezing can improve the stability of the care kit when storing it, and can effectively prevent it from falling off during the disinfection process.

[0021] Working principle: During the massage of the patient's arm, the downward movement of the force plate 187 pushes the T-shaped plate 192 downward, which in turn drives the arc-shaped plate 193 downward. This external force stimulates local tissue activity, further reducing the time blood stagnates in blood vessels and thus lowering the risk of thrombosis caused by slow blood flow. When the limiting frame 8 is removed, it releases the pressure on the pressure plate 199, which releases the pressure on the nursing kit inside the storage box 197. The squeezing action improves the stability of the nursing kit during storage, effectively preventing it from falling off during the sterilization process.

[0022] This invention provides an infection-preventing and monitorable biomedical hemodialysis arteriovenous fistula care kit. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
