Description

Technical Field

[0001] This invention belongs to the field of medical auxiliary equipment technology, and specifically discloses an adsorption-type hemodialysis device. Background Technology

[0002] The adsorption-type hemodialysis machine has a partitioned internal structure. The front section is filled with activated carbon or resin adsorption filler, while the rear section is encapsulated with a hollow fiber dialysis membrane. Blood flows in through the inlet, first passing through the adsorption section where large and medium-sized toxins are adsorbed by the adsorption medium, before entering the hollow fiber cavity. The dialysate flows counter-currently on the outside of the fiber, removing small molecule solutes such as creatinine and urea through diffusion and ultrafiltration, simultaneously completing the body's dehydration. A single cylinder integrates both perfusion and dialysis purification functions.

[0003] In existing adsorption hemodialysis machines, air purging requires medical staff to repeatedly squeeze the external blood circuit tubing to drive out the gas accumulated inside the tubing and dialysis chamber through vibration. While pre-purging, the position of air bubbles in the tubing is observed, and the trapped air is expelled segment by segment until the end of dialysis. Therefore, continuous manual observation and air purging are required, which increases the workload of medical staff. If air purging is not timely, air bubbles are likely to remain and enter the body with the blood, increasing the risk of air embolism. Summary of the Invention

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-10 The illustrated adsorption-type hemodialysis machine includes a hemodialysis cylinder body 1. A blood inlet tube 2 is fixedly connected to the top of the hemodialysis cylinder body 1, allowing blood to enter. A blood outlet tube 3 is fixedly connected to the bottom of the hemodialysis cylinder body 1, allowing blood to exit. A gas storage mechanism 6 is provided at the outer bottom of the hemodialysis cylinder body 1. The gas storage mechanism 6 is used to collect air flowing into the hemodialysis cylinder body 1. An automatic exhaust mechanism 7 is provided at the top of the gas storage mechanism 6, used to automatically exhaust the air from the gas storage mechanism 6. The hemodialysis cylinder body 1 is equipped with a protective mechanism 8 to protect the hemodialysis cylinder body 1. The dialysate outlet tube 4 is fixedly connected to the top of the hemodialysis cylinder body 1, and dialysate enters through the dialysate outlet tube 4. The dialysate inlet tube 5 is fixedly connected to the bottom of the hemodialysis cylinder body 1, and dialysate inlet tube 5 discharges the dialysate. The blood inlet tube 2 and the blood outlet tube 3 are both threaded with sealing caps. The dialysate outlet tube 4 and the dialysate inlet tube 5 are threaded with protective caps. The sealing caps and protective caps are unscrewed when using the dialyzer.

[0022] The gas storage mechanism 6 includes an external gas collection chamber 601, which can temporarily store blood and air. The external gas collection chamber 601 is rotatably connected to the bottom of the hemodialysis cylinder body 1. A vent pipe 602 is fixedly connected to the top and bottom of the external gas collection chamber 601, allowing air to pass through. A limiting cylinder 603 is fixedly connected to the bottom of the vent pipe 602. The outer wall of the limiting cylinder 603 has multiple through holes 604. An internal float 605 is provided, which can block the bottom of the ventilation tube 602 to prevent blood from being discharged. Blood can enter through the hole 604, causing the float 605 to float. A counterweight ring 606 is fixedly connected to the bottom of the external gas collection chamber 601, which can make gravity downward. A liquid-filled hose 607 is fixedly connected to the bottom of the external gas collection chamber 601, and the other end of the liquid-filled hose 607 is rotatably connected to the outside of the blood outlet tube 3. During hemodialysis, blood enters through the inlet tube 2 and exits through the outlet tube 3. As blood exits through the outlet tube 3, its high density and strong inertia cause most of it to flow along the hemodialysis cylinder body 1 towards the outlet tube 3. Since the density of air bubbles is much lower than that of blood, they float due to liquid buoyancy and blood flow disturbance, making it easier for them to enter the generally upward-trending fluid inlet tube 607 and then the external gas collection chamber 601. Simultaneously, some blood also flows along the fluid inlet tube 607 into the external gas collection chamber 601 and through the through-hole 604 into the limiting cylinder 603. Under the buoyancy of the blood, this causes the float 605 to rise. Once the float 605 rises, it blocks... After the bottom of the vent tube 602, the gas will no longer be discharged from the top of the external gas collection chamber 601. As the internal air pressure of the external gas collection chamber 601 increases, the blood will be squeezed out to the bottom of the external gas collection chamber 601 under the action of air pressure. Therefore, the blood level inside the external gas collection chamber 601 will drop. When the blood level inside the external gas collection chamber 601 drops, the float 605 will lose buoyancy and fall downward. At this time, the air pressure inside the external gas collection chamber 601 can be discharged through the automatic venting mechanism 7. When the air pressure inside the external gas collection chamber 601 decreases, the blood will re-enter the external gas collection chamber 601, thus realizing automatic repeated venting without manual venting.

[0023] The automatic exhaust mechanism 7 includes a venting pipe 701, which provides an installation position and ventilation space. The bottom of the venting pipe 701 is threadedly connected to the top of the external air collection chamber 601. A plug cylinder 702 is slidably connected inside the venting pipe 701. Multiple vent holes 703 are formed on the outer wall of the plug cylinder 702. When the plug cylinder 702 is inside the venting pipe 701, it can block the venting pipe 701. After the vent holes 703 move out of the venting pipe 701, gas can be discharged. A spacer ring 70 is fixedly connected inside the venting pipe 701. 5. The spacer ring 705 provides an installation position. A tension spring 706 is installed inside the plug cylinder 702. One end of the tension spring 706 is fixedly connected to the inside of the plug cylinder 702, and the other end is fixedly connected to the top of the spacer ring 705. A micro filter element 707 is installed inside the venting installation tube 701, located below the spacer ring 705. The micro filter element 707 filters the gas, preventing external gas and impurities from entering the venting installation tube 701. A top cover 704 is fixedly connected to the top of the vent hole 703, and the top cover 704 can cover the top of the venting installation tube 701. When the pressure inside the external gas collection chamber 601 is high, it enters the venting installation pipe 701 through the vent pipe 602, which pushes the plug cylinder 702 upward against the tension of the tension spring 706. After the vent hole 703 moves out of the venting installation pipe 701, the gas can be discharged through the vent hole 703. When the gas pressure decreases, the plug cylinder 702 moves downward under the tension of the tension spring 706. When the vent hole 703 re-enters the venting installation pipe 701, it can maintain the seal inside the external gas collection chamber 601. When the gas is discharged, the micro filter element 707 can filter it to prevent external impurities from entering the external gas collection chamber 601.

[0024] The protection mechanism 8 includes two slide rails 801 and two mounting plates 803. The inner sides of the two slide rails 801 are fixedly connected to the outer sides of the hemodialysis cylinder body 1, respectively. The mounting plate 803 has a mounting groove 804 inside, which provides space for the slide rails 801 to slide into. The slide rails 801 are slidably connected inside the mounting grooves 804. The mounting plate 803 provides the mounting position. The slide rails 801 have fixing holes 802 inside. The mounting plate 803 has a fixing seat 805 fixedly connected to the outside. The fixing seat 805 provides the mounting position and is located away from the hemodialysis cylinder. A mounting cylinder 806 is fixedly connected to one end of the cylinder body 1, providing an installation position. A limiting disc 807 is fixedly connected to the end of the mounting cylinder 806 away from the fixing seat 805. Multiple sliding grooves 808 are formed on the outer wall of the mounting cylinder 806. A sliding disc 809 is slidably connected to the outside of the mounting cylinder 806. The sliding disc 809 can slide outside the mounting cylinder 806 and inside the sliding grooves 808. An insertion rod 810 is slidably connected inside the mounting cylinder 806. The sliding disc 809 is installed outside the insertion rod 810, and the outside of the insertion rod 810 is fixedly connected to the sliding disc 807. Inside the sliding plate 809, the inner side of the sliding plate 809 is slidably connected to the inside of the slide groove 808. Two fixing rods 811 are fixedly connected to the outside of the sliding plate 809. A fixing rail 813 is fixedly connected to the outside of the mounting plate 803. A push block 814 is slidably connected to the outside of the fixing rail 813. The push block 814 can press the fixing rods 811. A protective frame 815 is fixedly connected to the outside of the mounting plate 803. The protective frame 815 has elasticity to protect the hemodialysis cylinder body 1, can relieve force, and thus protect the hemodialysis cylinder body 1. It can also be easily hung on other objects. The hemodialysis cylinder body 1 is supported, providing space for the external gas collection chamber 601 to rotate. A spring 812 is sleeved on the outside of the mounting cylinder 806. The spring 812 can push the sliding disk 809 to move towards the hemodialysis cylinder body 1. The insertion rod 810 is engaged with the inside of the fixing hole 802. One end of the spring 812 is fixedly connected to the end of the limiting disk 807 near the mounting plate 803, and the other end of the spring 812 is fixedly connected to the end of the sliding disk 809 away from the mounting plate 803. The insertion rod 810 passes through the middle of the fixing seat 805 and the outer wall of the mounting plate 803. When disassembling the protective mechanism 8, first push the push block 814 upwards. Since the push block 814 is inclined, when the push block 814 moves, it can squeeze the fixing rod 811 away from the hemodialysis cylinder body 1, thereby moving the sliding plate 809 away from the hemodialysis cylinder body 1 and compressing the spring 812. When the sliding plate 809 moves, it can drive the insertion rod 810 away from the hemodialysis cylinder body 1, so that the insertion rod 810 can move out of the fixing hole 802. At this time, when the push block 814 is pushed further, the mounting plate 803 can be pushed out of the slide rail 801, so that the mounting plate 803 can be removed from the outside of the slide rail 801. Therefore, the protective frame can be removed. When the 815 is removed from the outside of the hemodialysis cylinder body 1 and the mounting plate 803 is installed, the push block 814 is pushed upward and the mounting plate 803 is slid into the outside of the slide rail 801. When the insertion rod 810 moves to the position of the fixing hole 802, the push block 814 is released. At this time, under the reaction force of the spring 812, the sliding plate 809 and the insertion rod 810 can be pushed towards the hemodialysis cylinder body 1, so that the insertion rod 810 can be inserted into the inside of the fixing hole 802. Then the mounting plate 803 can be installed on the outside of the hemodialysis cylinder body 1, realizing the installation of the protective frame 815. Therefore, the existence of the protective frame 815 can protect the hemodialysis cylinder body 1 and provide a rotation space for the external gas collection chamber 601.

[0025] Working principle: During hemodialysis, blood enters through the inlet tube 2 and exits through the outlet tube 3. As blood exits through the outlet tube 3, its high density and strong inertia cause most of it to flow along the hemodialysis cylinder body 1 towards the outlet tube 3. Since the density of air bubbles is much lower than that of blood, they float due to liquid buoyancy and blood flow disturbance, making it easier for them to enter the generally upward-trending fluid inlet tube 607 and then the external gas collection chamber 601. Simultaneously, some blood also flows along the fluid inlet tube 607 into the external gas collection chamber 601 and through the through-hole 604 into the limiting cylinder 603. Under the buoyancy of the blood, the float 605 rises. When the float 605 rises... After being blocked at the bottom of the vent pipe 602, the gas will no longer be discharged from the top of the external gas collection chamber 601. As the internal air pressure of the external gas collection chamber 601 increases, the blood will be squeezed out to the bottom of the external gas collection chamber 601 under the action of air pressure. Therefore, the blood level inside the external gas collection chamber 601 will drop. When the blood level inside the external gas collection chamber 601 drops, the float 605 will lose buoyancy and fall downward. At this time, the air pressure inside the external gas collection chamber 601 can be discharged through the automatic venting mechanism 7. When the air pressure inside the external gas collection chamber 601 decreases, the blood will re-enter the external gas collection chamber 601, thus realizing automatic repeated venting without manual venting. When the pressure inside the external gas collection chamber 601 is high, it enters the venting installation pipe 701 through the vent pipe 602, which pushes the plug cylinder 702 upward against the tension of the tension spring 706. After the vent hole 703 moves out of the venting installation pipe 701, the gas can be discharged through the vent hole 703. When the gas pressure decreases, the plug cylinder 702 moves downward under the tension of the tension spring 706. When the vent hole 703 enters the venting installation pipe 701 again, it can maintain the seal inside the external gas collection chamber 601. When the gas is discharged, the micro filter element 707 can filter it to prevent external impurities from entering the external gas collection chamber 601. When disassembling the protective mechanism 8, first push the push block 814 upwards. Since the push block 814 is inclined, when the push block 814 moves, it can squeeze the fixing rod 811 away from the hemodialysis cylinder body 1, thereby moving the sliding plate 809 away from the hemodialysis cylinder body 1 and compressing the spring 812. When the sliding plate 809 moves, it can drive the insertion rod 810 away from the hemodialysis cylinder body 1, so that the insertion rod 810 can move out of the fixing hole 802. At this time, when the push block 814 is pushed further, the mounting plate 803 can be pushed out of the slide rail 801, so that the mounting plate 803 can be removed from the outside of the slide rail 801. Therefore, the protective frame can be removed. When the 815 is removed from the outside of the hemodialysis cylinder body 1 and the mounting plate 803 is installed, the push block 814 is pushed upward and the mounting plate 803 is slid into the outside of the slide rail 801. When the insertion rod 810 moves to the position of the fixing hole 802, the push block 814 is released. At this time, under the reaction force of the spring 812, the sliding plate 809 and the insertion rod 810 can be pushed towards the hemodialysis cylinder body 1, so that the insertion rod 810 can be inserted into the inside of the fixing hole 802. Then the mounting plate 803 can be installed on the outside of the hemodialysis cylinder body 1, realizing the installation of the protective frame 815. Therefore, the existence of the protective frame 815 can protect the hemodialysis cylinder body 1 and provide a rotation space for the external gas collection chamber 601.
