Description

Technical Field

[0001] This invention relates to the field of dialysis water supply machine technology, and in particular to a portable and mobile dialysis water supply machine. Background Technology

[0002] During hemodialysis, dialysate preparation, and related treatments, the water supply system needs to continuously and stably provide RO pure water that meets the requirements. RO reverse osmosis filtration is the core purification unit in the dialysis water supply system, and it is usually used in conjunction with booster pumps, input pipelines, pure water pipelines, wastewater pipelines, wastewater proportioning valves, ultraviolet sterilization tubes, etc.

[0003] In existing technologies, RO filtration for dialysis water supply uses a single RO filter. During use, the RO membrane may experience a decrease in pure water flux and an increase in wastewater ratio due to contamination, scaling, and compaction. When the pure water output decreases or the water quality fails to meet standards, the equipment must be stopped and the RO membrane or filter must be replaced manually. This method can lead to an interruption of dialysis water supply, making it difficult to meet the requirements for continuous dialysis treatment and causing the water supply machine to be unable to provide pure water in real time during dialysis. Summary of the Invention

[0004] In view of the problems in the above-mentioned or existing technologies, such as the decrease in pure water flux and increase in wastewater ratio caused by pollution, scaling and compaction of RO membranes during use, and the need to stop equipment operation and manually replace RO membranes or RO filters when pure water output decreases or water quality fails to meet standards, this invention is proposed.

[0007] The water supply unit is equipped with an RO filter assembly and a process switching component located at the end of the RO filter assembly.

[0013] The switching component includes a riser tube disposed on the upper part of the delay box and an isolation block disposed inside the riser tube.

[0014] As the isolation block is lifted by the wastewater inside the delay box, it gradually closes off the outflow of wastewater from the delay box while simultaneously opening the connection between the first RO filter and the second RO filter.

[0022] As a preferred embodiment of the portable and mobile dialysis water supply machine of the present invention, a limiting member is provided at the upper part of the riser pipe.

[0023] In a preferred embodiment of the portable and mobile dialysis water supply machine of the present invention, the limiting member includes a side tube disposed on the upper part of the riser tube, an insertion rod disposed on the inner wall of the side tube, a spring disposed on the outer wall of the insertion rod, and a connecting ring disposed on the outer wall of the spring.

[0024] The beneficial effects of the portable and mobile dialysis water supply machine of the present invention are as follows: The present invention uses the wastewater output of the first RO filter to benchmark the change in its pure water output, and then drives the isolation block to take over the work of the second RO filter by the increase in its wastewater output. Then, when the isolation block rises to the top, the second RO filter completely dominates the pure water output of the water supply machine, ensuring the continuous output of pure water during the switching of RO filters and ensuring uninterrupted dialysis treatment.

[0052] Furthermore, one end of the second input pipe 222 is fixedly connected to the outer wall of the middle pipe 213, and the inner wall of the second input pipe 222 is in communication with the inner wall of the middle pipe 213.

[0053] Specifically, the outflow component 31 also includes a manifold 313 disposed inside the delay box 312 and a limiting grid 314 disposed inside the delay box 312, and the side wall of the delay box 312 is provided with an outlet 315.

[0054] Furthermore, the limiting grid plate 314 is located at the lower part of the riser pipe 331, and the outer wall of the limiting grid plate 314 is fixedly connected to the inner wall of the delay box 312. The outer wall of the limiting grid plate 314 has multiple through holes for wastewater to pass through. The outlet 315 is located on the side wall of the delay box 312, and the inner wall of the limiting grid plate 314 is connected to the inner wall of the delay box 312. The outlet 315 is connected to the wastewater discharge pipe.

[0055] Specifically, the switching component 33 also includes a rising cavity 332 disposed on the upper part of the rising pipe 331 and an insertion groove 336 disposed on the outer wall of the isolation block 335. A connecting pipe 333 is disposed in the middle of the rising pipe 331, and a connecting cavity 334 is disposed on the inner wall of the connecting pipe 333.

[0056] Furthermore, the rising cavity 332 is located on the top surface of the insulating block 335, and the rising cavity 332 is formed between the top surface of the insulating block 335 and the top surface of the inner wall of the rising pipe 331. The top surface of the rising pipe 331 is provided with an air port extending to the inner wall of the rising cavity 332. There are two insertion slots 336, which are symmetrically opened on the upper outer wall of the insulating block 335 and correspond to each other. The connecting pipe 333 is located in the middle of the rising pipe 331, and the two ends of the connecting pipe 333 are fixedly connected to the second input pipe 222. The inner wall of the second input pipe 222 is connected to the connecting cavity 334 inside the connecting pipe 333. The insulating block 335 is located in the middle of the connecting cavity 334.

[0057] Preparation: Move the water supply machine 11 to the required working position. At this time, the water supply machine 11 moves by the wheels on the lower part of the mobile frame 1. After moving to the designated working position, connect the first input pipe 212 to the output end of the booster pump. Then connect the output pipe of the ultraviolet sterilization pipe of the water supply machine 11 to the dialysis pure water input component. Then run the water supply machine 11.

[0058] When the pressurized water flows to the inner wall of the first input pipe 212 and enters the inner wall of the first RO filter 211 through the first input pipe 212, when the inner wall of the first RO filter 211 is filled with pressurized water, the water will pass through the RO membrane inside the first RO filter 211 to form pure water and flow into its inner wall through the hole on the outer wall of the first pure water pipe 215. It will then flow out along the inner wall of the first pure water pipe 215 and enter the ultraviolet sterilization tube. The water that does not pass through will form wastewater and flow into the inner wall of the first pure water pipe 215. The wastewater will flow into the inner wall of the output pipe 311 along the inner wall of the first pure water pipe 215 and into the inner wall of the delay box 312. When the wastewater level inside the delay box 312 is higher than the bottom surface of the inner wall of the outlet 315, the wastewater will flow into the wastewater output pipe along the inner wall of the outlet 315 and be discharged.

[0059] When the pure water output of the first RO filter 211 decreases, the amount of wastewater inside the delay box 312 gradually increases, and the outlet 315 cannot discharge the wastewater in time: At this time, because the outlet 315 cannot discharge the wastewater inside the delay box 312 at the same time, the wastewater inside the delay box 312 continues to increase. At this time, the wastewater inside the delay box 312 will lift the isolation block 335 through buoyancy.

[0060] When the isolation block 335 rises: During the rising process of the isolation block 335, it will continuously rise according to the rising height of the waste water level inside the delay box 312. The isolation block 335 gradually opens the middle of the connecting cavity 334, and at this time, the connecting cavity 334 will be connected to the second input pipe 222. At this time, the pressurized water continuously input by the first input pipe 212 will flow into the inner wall of the connecting cavity 334 through the second input pipe 222, and enter the input end of the second RO filter 221 along the inner wall of the connecting cavity 334, and enter the inner wall of the second RO filter 221. When the inner wall of the second RO filter 221 is full of pressurized water... At this time, the pressurized water will pass through the RO membrane inside the second RO filter 221 to form pure water, and the water that does not pass through the RO membrane inside the second RO filter 221 will form wastewater. The pure water inside the second RO filter 221 will flow into the inner wall of the second pure water pipe 223 through the hole on the outer wall of the second pure water pipe 223, and enter the inner wall connected to the first pure water pipe 215 along the inner wall of the second pure water pipe 223, and flow out along the common pure water output end into the inner wall of the ultraviolet sterilization pipe. After sterilization, it is input to the dialysis pure water input end. The wastewater inside the second RO filter 221 flows out along the inner wall of the second wastewater pipe 224 and is discharged.

[0061] When the filtration efficiency of the first RO filter 211 reaches the minimum threshold for pure water production: at this time, the wastewater production of the first RO filter 211 reaches the maximum threshold. At this time, the isolation block 335 rises to the highest point, and the isolation block 335 fully opens the connection cavity 334 to the maximum state at the input end of the second RO filter 221. At this time, the second RO filter 221 will take the lead in controlling the production of pure water.

[0062] Example 2, refer to Figures 6 to 7 This is the second embodiment of the present invention, which provides a portable and mobile dialysis water supply machine that enables rapid switching between RO filtration units.

[0063] Specifically, the process switching component 3 also includes a lifting member 32 disposed on the side wall of the limiting grid plate 314.

[0064] Furthermore, the lifting member 32 is located on the side wall of the limiting grid plate 314, and the lifting member 32 is located directly below the riser pipe 331. The lifting member 32 corresponds to the lower part of the buoyancy block 321.

[0065] Specifically, the lifting component 32 includes a buoyancy block 321 disposed on the side wall of the limiting grid plate 314, a rising rod 322 disposed on the upper part of the buoyancy block 321, an extension rod 323 disposed on the bottom surface of the buoyancy block 321, and a closing plate 324 disposed on the bottom surface of the extension rod 323.

[0066] Furthermore, the outer wall of the buoyancy block 321 is in contact with the inner wall of the delay box 312, and the inner wall of the buoyancy block 321 is hollow. The top surface of the middle part of the buoyancy block 321 is fixedly connected to the bottom surface of the rising rod 322. The bottom surface of the middle part of the buoyancy block 321 is fixedly connected to the top surface of the extension rod 323. The bottom surface of the extension rod 323 is fixedly connected to the top surface of the sealing plate 324. The side wall of the sealing plate 324 is in contact with the inner wall of the delay box 312 near the outlet 315. The side area of ​​the outlet 315 is larger than the cross-sectional area of ​​the outlet 315.

[0067] Specifically, the top of the rising rod 322 is connected to the bottom of the insulating block 335.

[0068] Furthermore, the bottom surface of the isolation block 335 is fixedly connected to the top surface of the rising rod 322, and the upper end of the rising rod 322 is located in the middle of the inner wall of the rising tube 331.

[0069] Workflow

[0070] When the wastewater inside the delay box 312 continues to rise: At this time, the wastewater level inside the delay box 312 is higher than the threshold of the discharge from the outlet 315 because the amount of wastewater produced by the first RO filter 211 is greater than the threshold of the discharge from the outlet 315. At this time, the water inside the delay box 312 continues to rise. Since the buoyancy block 321 is hollow, the buoyancy block 321 floats up along the inner wall of the delay box 312 because of the wastewater inside the delay box 312.

[0071] When the delay box 312 floats: At this time, the buoyancy block 321 drives the extension rod 323 connected to its bottom surface to move upward. The extension rod 323 drives the sealing plate 324 fixedly connected to its surface to move upward. When the sealing plate 324 moves upward, the sealing plate 324 assembly closes the connection between the outlet 315 and the inside of the delay box 312. At this time, the wastewater discharge from the outlet 315 gradually decreases. Simultaneously, the wastewater level inside the delay box 312 rises rapidly because the wastewater discharge from the outlet 315 gradually decreases. The rising wastewater level lifts the buoyancy block 321 to float.

[0072] When the buoyancy block 321 rises, it simultaneously drives the rising rod 322 connected to its top surface to move upward. The rising buoyancy block 321 lifts the interconnected isolation block 335 and moves it upward along the inner wall of the riser pipe 331. Due to the accelerated rise of the wastewater level inside the delay box 312, the isolation block 335 rises at this time with acceleration. The rising isolation block 335 opens the connection channel between the connecting cavity 334 and the input end of the second RO filter 221. At this time, the pressurized water flows into the input end of the second RO filter 221. At this time, the second RO filter 221 will dominate the production of pure water.

[0073] Example 3, referring to Figure 7The third embodiment of the present invention provides a portable and mobile dialysis water supply machine that can achieve the effect of switching RO filtration as the wastewater from the RO filtration unit gradually increases.

[0074] Specifically, a limiter 4 is provided at the upper part of the riser tube 331.

[0075] Furthermore, the limiting member 4 is disposed on the upper outer wall of the riser pipe 331 and corresponds to the isolation block 335.

[0076] Specifically, the limiting component 4 includes a side tube 41 disposed on the upper part of the riser tube 331, an insertion rod 42 disposed on the inner wall of the side tube 41, a spring 43 disposed on the outer wall of the insertion rod 42, and a connecting ring 44 disposed on the outer wall of the spring 43.

[0077] Furthermore, there are two side tubes 41, which are symmetrically arranged on the upper outer wall of the riser tube 331. Each side tube 41 corresponds to an insertion slot 336. The side tubes 41 and the riser tube 331 are fixedly connected to each other. Each side tube 41 has an insertion rod 42 on its inner wall. The insertion rod 42 is slidably connected to the inner wall of the side tube 41. Each insertion rod 42 has a spring 43 on its outer wall. The end face of the spring 43 is fixedly connected to the end face of the inner wall of the side tube 41. Each insertion rod 42 has a connecting ring 44 on its outer wall. The connecting ring 44 is fixedly connected to the insertion rod 42. The connecting ring 44 is slidably connected to the inner wall of the side tube 41. The other end face of the spring 43 is fixedly connected to the end face of the connecting ring 44.

[0078] One end of the insertion rod 42 extends to the inner wall of the rising cavity 332, and the other end of the insertion rod 42 extends to the end of the side tube 41. The end of the insertion rod 42 located inside the rising cavity 332 corresponds to the insertion groove 336.

[0079] Running process

[0080] When the isolation block 335 accelerates and rises along the inner wall of the riser pipe 331: when the isolation block 335 rises to the maximum height of the inner wall of the riser pipe 331, the isolation block 335 pushes open the two corresponding insertion rods 42 through the insertion groove 336 on the outer wall. At this time, the insertion rods 42 will slide along the top surface of the isolation block 335 into the inner wall of the insertion groove 336. During this process, the spring 43 is compressed first. When the end of the insertion rod 42 slides into the concave part of the insertion groove 336, the end face of the insertion rod 42 is pushed into the concave part of the insertion groove 336 by the elastic force of the spring 43. At this time, the two insertion rods 42 limit the isolation block 335 through the insertion groove 336.

[0081] When the isolation block 335 rises to its highest position: At this time, the first RO filter 211 can still produce pure water, but the actual pure water output of the first RO filter 211 is lower than the normal threshold, resulting in excessive wastewater output. At this time, the second RO filter 221 will be controlled by the rise of the isolation block 335, the input of stepped pressurized water, and the pure water output will be dominated. Then, the output pure water will be combined and flow into the ultraviolet sterilization tube and into the dialysis water storage component.

[0082] After use, the pressurized water input stops, and the wastewater accumulated inside the delay box 312 is discharged. Then, the first RO filter 211 is replaced. After the first RO filter 211 is replaced, the operator needs to manually pull the two ends of the two insertion rods 42 in opposite directions. At this time, the insertion rods 42 compress the spring 43 through the connecting ring 44. The insertion rods 42 move along the inner wall of the side pipe 41. At this time, the insertion rods 42 will release the restriction of the isolation block 335 through the insertion groove 336. At this time, the isolation block 335 is released and falls to the middle of the connecting cavity 334. At this time, the isolation block 335 will break the connection between the second input pipe 222 and the connecting cavity 334. At this time, the pressurized water flow path returns to entering the inner wall of the middle pipe 213 along the first input pipe 212 and flowing into the inner wall of the first RO filter 211.
