Description

Technical Field

[0001] This invention relates to the field of hemodialysis concentrate production technology, and in particular to a hemodialysis concentrate preparation and mixing device. Background Technology

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It involves drawing blood from the body and passing it through a dialyzer composed of numerous hollow fibers. The blood exchanges substances with an electrolyte solution (dialysis fluid) containing a concentration similar to that in the body through diffusion, ultrafiltration, adsorption, and convection within and outside the hollow fibers. This process removes metabolic waste, maintains electrolyte and acid-base balance, and removes excess water. The purified blood is then returned to the body. The entire process is called hemodialysis.

[0003] The hemodialysis concentrate consists of concentrate A and concentrate B. Concentrate A is composed of an aqueous solution of sodium chloride, potassium chloride, calcium chloride, magnesium chloride, and glacial acetic acid. Concentrate B is composed of an aqueous solution of sodium bicarbonate or sodium bicarbonate and sodium chloride. When producing hemodialysis concentrate, the materials need to be thoroughly mixed with the water source.

[0004] In the prior art, Chinese patent application number 202120979345.1 discloses a mixing device for hemodialysis concentrate, including a base, two support columns, and a liquid tank. The two support columns are fixedly installed on the upper surface of the base, and the lower surface of the liquid tank is fixedly connected to the upper ends of the two support columns. Two connecting columns are fixedly installed on both the lower surface of the liquid tank and the upper surface of the base. The four connecting columns are fixedly connected to a mixing cylinder. A liquid outlet is opened at the bottom of the mixing cylinder, and a circulation pump is fixedly installed outside the liquid outlet. A three-way pipe is fixedly installed at the outlet of the circulation pump. Water pipes are fixedly installed at both the left and right ends of the three-way pipe. The upper ends of the two water pipes penetrate the corresponding side walls of the mixing cylinder. A stirring mechanism is provided inside the mixing cylinder. This invention can fully mix two liquids and eliminate air bubbles generated during the stirring process.

[0005] However, the above-mentioned technical solutions have the drawbacks of not filtering the dialysate during discharge after preparation, resulting in the presence of fine particles inside the dialysate, which affects its quality and subsequent use. Furthermore, the lack of dialysate dispensing necessitates additional filling equipment, increasing production costs and reducing processing efficiency. Therefore, this application proposes a hemodialysis concentrate preparation and mixing device to solve the above problems. Summary of the Invention

[0006] Based on the existing technical issues, after the dialysate is prepared, there is no filtration during discharge, resulting in the presence of fine particles inside the dialysate, which affects its quality and subsequent use. Furthermore, there is no dispensing function for the dialysate, requiring additional filling equipment, which increases production costs and reduces processing efficiency. This invention proposes a mixing and preparation device for hemodialysis concentrate.

[0007] The present invention discloses a mixing device for preparing hemodialysis concentrate, comprising a base plate, and the mixing device further comprising: The support legs are provided in two parts, and the bottom ends of both support legs are fixedly installed on the top of the base plate; A mixing cylinder, the bottom and right end of which are fixedly mounted on two support legs respectively, and a feeding port is provided at the top of the mixing cylinder; A stirring assembly is disposed inside the mixing cylinder and is used to stir and mix the dialysate; The discharge assembly includes: a discharge pipe, an electrically controlled valve, a filter box, a filter screen, a discharge pipe, a water pump, a discharge valve, and a discharge nozzle. The top end of the discharge pipe is fixedly connected to the bottom of the mixing cylinder. The electrically controlled valve is fixedly installed inside the discharge pipe. The top end of the filter box is fixedly connected to the bottom end of the discharge pipe. The left end of the filter screen passes through the right side of the filter box and extends into the interior of the filter box. The top end of the discharge pipe is fixedly connected to the bottom of the filter box. The water pump and the discharge valve are both fixedly installed on the discharge pipe. The discharge nozzle is installed at the bottom end of the discharge pipe. A clip-on assembly is located on the right side of the filter box and engages with the right end of the filter screen. The dispensing assembly is located on the top of the base plate and cooperates with the discharge nozzle.

[0008] With the above structure, by opening the electrically controlled valve and the discharge valve, and then starting the water pump, the dialysate after mixing inside the mixing tank can be extracted. At this time, the dialysate will enter the interior of the filter box and be filtered through the filter screen. After filtration, the dialysate will be discharged and collected through the discharge pipe and the outlet. This method can achieve efficient filtration of the mixed dialysate. The filter screen uses a 0.22μm sterile-grade filter membrane, which can effectively remove particles and microorganisms in the dialysate and ensure the quality of the dialysate.

[0009] Preferably, the stirring assembly includes a first motor, a rotating shaft, multiple stirring rods, two first scrapers, multiple fixing rods, and multiple second scrapers. The first motor is fixedly installed at the left end of the mixing cylinder. The output shaft of the first motor passes through the left side of the mixing cylinder and is fixedly installed at the left end of the rotating shaft. The right end of the rotating shaft is rotatably connected to the right inner wall of the mixing cylinder. One end of each of the multiple stirring rods is fixedly installed on the rotating shaft. The two first scrapers are in sliding contact with the interior of the mixing cylinder on opposite sides. The other end of each stirring rod is fixedly installed on the corresponding first scraper. One end of each fixing rod is fixedly installed on the corresponding stirring rod. The other end of each fixing rod is fixedly installed on the corresponding second scraper. One side of each second scraper is in sliding contact with one inner wall of the mixing cylinder.

[0010] Furthermore, by starting the first motor, the rotating shaft, multiple stirring rods, two first scrapers, multiple fixed rods, and multiple second scrapers can be driven to rotate. At this time, the multiple stirring rods can achieve efficient stirring and mixing of the dialysis fluid, and the rotation of the two first scrapers and multiple second scrapers can scrape and clean the inner wall of the mixing cylinder, thereby preventing the dialysis fluid raw material from adhering to the inner wall or precipitating, thus improving the efficiency and effect of mixing.

[0011] Preferably, the clamping assembly includes a rotating cover, a sealing plate, a handle, a clamping rod, and a spring. The bottom end of the rotating cover is rotatably connected to the right side of the filter box. The sealing plate is fixedly installed on the left side of the rotating cover. The left side of the sealing plate contacts the right end of the filter screen and the right side of the filter box, respectively. The handle is fixedly installed on the right side of the rotating cover. The left end of the clamping rod is slidably connected to the right side of the filter box. The right end of the clamping rod is clamped to the top end of the rotating cover. The top end of the spring is fixedly installed on the right side of the filter box, and the bottom end of the spring is fixedly installed on the top end of the clamping rod.

[0012] Furthermore, by inserting the left end of the filter screen into the filter box, and then rotating the cover upwards so that the sealing plate contacts the right side of the filter box, the top of the cover can press the locking rod upwards as it rotates upwards. Then, when the cover is vertical, the spring force drives the locking rod downwards to lock and fix the cover. At this point, the sealing plate can stably install, fix and seal the filter screen. Then, by reversing the above operation, the filter screen can be quickly disassembled. This method allows for quick installation and removal of the filter screen, facilitating subsequent maintenance or replacement.

[0013] Preferably, a sliding groove is provided on the right side of the filter box, and the left end of the clamp rod is slidably connected in the sliding groove.

[0014] Furthermore, by creating a sliding groove, the lever can be stably limited and supported in a sliding manner.

[0015] Preferably, the dispensing assembly includes a second motor, a first turntable, multiple electric push rods, a second turntable, and multiple storage bins. The second motor is fixedly mounted on the top of the base plate, the bottom of the first turntable is fixedly mounted on the output shaft of the second motor, the bottom ends of the multiple electric push rods are all fixedly mounted on the top of the first turntable, the output shafts of the multiple electric push rods are all fixedly mounted on the bottom of the second turntable, and the multiple storage bins are placed on the top of the second turntable. The multiple storage bins are all matched with the discharge nozzle.

[0016] Furthermore, by placing multiple storage bins sequentially on top of the second turntable, and then activating the second motor, the first turntable, multiple electric push rods, the second turntable, and the multiple storage bins can be rotated. This allows the multiple storage bins to align sequentially with the bottom of the discharge nozzle, facilitating sequential filling operations. Activating the multiple electric push rods can raise and lower the second turntable and the multiple storage bins. Raising the storage bins allows the bottom of the discharge nozzle to be inserted into the storage bin, facilitating precise filling and preventing spillage. Furthermore, lowering the storage bins allows multiple storage bins to be rotated and repositioned after a single storage bin is filled, making it convenient to pick up and put away the storage bins.

[0017] Preferably, a plurality of sliding rods are fixedly installed at the bottom of the first turntable, and an annular groove is provided at the top of the base plate, with the bottom ends of the plurality of sliding rods slidably connected in the annular groove.

[0018] Furthermore, the sliding limit mechanism between the slide bar and the annular groove can improve the rotational stability of the first turntable, multiple electric push rods, the second turntable, and multiple storage tanks.

[0019] Preferably, the top of the second turntable has multiple placement slots at equal intervals in a ring, and the bottom of the storage bucket is placed in the corresponding placement slot.

[0020] Furthermore, by creating placement slots, the placement of storage barrels can be limited.

[0021] Preferably, anti-slip pads are fixedly installed on the bottom inner walls of each of the multiple placement slots, with the top of the anti-slip pads contacting the bottom of the corresponding storage bucket.

[0022] Furthermore, by setting anti-slip pads, displacement can be prevented when the storage tank rotates, thus improving the stability of the storage tank's movement.

[0023] The beneficial effects of this invention are: 1. By opening the electrically controlled valve and the discharge valve, and then starting the water pump, the dialysate after mixing inside the mixing tank can be extracted. At this time, the dialysate will enter the interior of the filter box and be filtered through the filter screen. After filtration, the dialysate will be discharged and collected through the discharge pipe and the outlet. This method can achieve efficient filtration of the mixed dialysate. The filter screen uses a 0.22μm sterile grade filter membrane, which can effectively remove particles and microorganisms in the dialysate and ensure the quality of the dialysate. 2. By starting the first motor, the rotating shaft, multiple stirring rods, two first scrapers, multiple fixed rods, and multiple second scrapers can be driven to rotate. At this time, the multiple stirring rods can achieve efficient stirring and mixing of the dialysis fluid, and the rotation of the two first scrapers and multiple second scrapers can scrape and clean the inner wall of the mixing cylinder, thereby preventing the dialysis fluid raw material from adhering to the inner wall or causing precipitation, thus improving the efficiency and effect of mixing. 3. By inserting the left end of the filter screen into the filter box, the rotating cover is then rotated upwards until the sealing plate contacts the right side of the filter box. As the rotating cover rotates upwards, its top end presses the locking rod upwards. When the rotating cover is vertical, the spring force drives the locking rod downwards, thus securing the rotating cover. At this point, the sealing plate can stably install, fix, and seal the filter screen. By reversing the above operation, the filter screen can be quickly disassembled. This method allows for quick installation and removal of the filter screen, facilitating subsequent maintenance or replacement. 4. By placing multiple storage bins sequentially on top of the second turntable, and then starting the second motor, the first turntable, multiple electric push rods, the second turntable, and multiple storage bins can be rotated. This allows the multiple storage bins to align with the bottom of the discharge nozzle in sequence, facilitating sequential filling operations. By starting the multiple electric push rods, the second turntable and multiple storage bins can be raised and lowered. As the storage bins rise, the bottom of the discharge nozzle can be inserted into the interior of the storage bin, facilitating accurate filling and preventing spillage. Furthermore, as the storage bins descend, after a single storage bin is filled, it can be moved downwards to allow multiple storage bins to rotate and exchange positions, making it convenient to pick up and put away the storage bins. This invention achieves efficient mixing during dialysate preparation and filtration during discharge through a simple structure, improving the production quality of dialysate. At the same time, it enables the prepared dialysate to be packaged and processed, reducing production costs and improving the processing efficiency of dialysate, making it highly practical.

The left side of the sealing plate 20 contacts the right end of the filter screen 14 and the right side of the filter box 13, respectively. The handle 21 is fixedly installed on the right side of the rotating cover 19. The left end of the clamping rod 22 is slidably connected to the right side of the filter box 13.

The bottom ends of the multiple electric push rods 29 are all fixedly mounted on the top of the first turntable 26, and the output shafts of the multiple electric push rods 29 are all fixedly mounted on the bottom of the second turntable 30. The multiple storage tanks 33 are all placed on the top of the second turntable 30, and each of the multiple storage tanks 33 cooperates with the discharge nozzle 18. By sequentially placing the multiple storage tanks 33 on the top of the second turntable 30, and then starting the second turntable 30...

Here, by activating the multiple electric push rods 29, the second turntable 30 and multiple storage tanks 33 can be raised and lowered. As the storage tanks 33 rise, the bottom of the discharge nozzle 18 can be inserted into the interior of the storage tanks 33, facilitating accurate filling and avoiding spillage. Furthermore, as the storage tanks 33 descend, after a single storage tank 33 is filled, it can be moved downwards to allow multiple storage tanks 33 to rotate and change positions, making it convenient to pick up and put down the storage tanks 33.

[0033] In this embodiment, a plurality of sliding rods 27 are fixedly installed at the bottom of the first turntable 26, and an annular groove 28 is provided at the top of the base plate 1. The bottom ends of the plurality of sliding rods 27 are slidably connected in the annular groove 28.

[0035] In this embodiment, anti-slip pads 32 are fixedly installed on the bottom inner walls of multiple placement slots 31. The top of the anti-slip pads 32 is in contact with the bottom of the corresponding storage buckets 33. By setting the anti-slip pads 32, displacement can be avoided when the storage buckets 33 rotate, thereby improving the movement stability of the storage buckets 33.

[0036] It should be noted that the specific models of the first motor 5, the electrically controlled valve 12, the water pump 16, the discharge valve 17, the second motor 25, and the electric push rod 29 used shall be selected by those skilled in the art. Furthermore, the first motor 5, the electrically controlled valve 12, the water pump 16, the discharge valve 17, the second motor 25, and the electric push rod 29 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0037] Working principle: In use, firstly, the first motor 5, electrically controlled valve 12, water pump 16, discharge valve 17, second motor 25, and electric push rod 29 are connected to an external power source. Then, dialysis fluid is added into the mixing cylinder 3 through the feeding port 4. After the dialysis fluid is added, starting the first motor 5 drives the rotating shaft 6, multiple stirring rods 7, two first scrapers 8, multiple fixing rods 9, and multiple second scrapers 10 to rotate. At this time, the multiple stirring rods 7 can achieve efficient stirring and mixing of the dialysis fluid, and the rotation of the two first scrapers 8 and multiple second scrapers 10 can scrape and clean the inner wall of the mixing cylinder 3, thereby preventing the dialysis fluid from adhering to the inner wall or causing sedimentation. To improve the efficiency and effectiveness of mixing, after the dialysate is mixed, the electro-controlled valve 12 and the discharge valve 17 are opened, and the water pump 16 is started to extract the mixed dialysate from the mixing tank 3. The dialysate then enters the filter tank 13 and is filtered through the filter screen 14. After filtration, the dialysate is discharged and collected through the discharge pipe 15 and the outlet 18. This method achieves efficient filtration of the mixed dialysate. The filter screen 14 uses a 0.22μm sterile-grade filter membrane, which effectively removes particles and microorganisms from the dialysate, ensuring its quality. Multiple storage tanks 33 are placed sequentially on the second turntable 30. At the top, the second motor 25 is activated, which drives the first turntable 26, multiple electric push rods 29, the second turntable 30, and multiple storage tanks 33 to rotate. This allows the multiple storage tanks 33 to align sequentially with the bottom of the discharge nozzle 18, facilitating sequential filling. Activating the multiple electric push rods 29 raises and lowers the second turntable 30 and the multiple storage tanks 33. Raising the storage tanks 33 allows the bottom of the discharge nozzle 18 to insert into the interior of the storage tank 33, facilitating precise filling and preventing spillage. Lowering the storage tanks 33 allows multiple storage tanks 33 to rotate and be repositioned after a single storage tank is filled, facilitating the removal and placement of the storage tanks 33. By inserting the left end of the filter screen 14 into the filter box 13, the rotating cover 19 is then rotated upwards, causing the sealing plate 20 to contact the right side of the filter box 13. As the rotating cover 19 rotates upwards, its top end can press the locking rod 22 upwards. When the rotating cover 19 is vertical, the spring force of the spring 24 drives the locking rod 22 downwards, thus fixing the rotating cover 19. At this time, the sealing plate 20 can stably install, fix, and seal the filter screen 14. Then, by reversing the above operation, the filter screen 14 can be quickly disassembled. This method enables quick disassembly and assembly of the filter screen 14, facilitating subsequent maintenance or replacement.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
