Description

Technical Field

[0001] The present invention relates to the technical field of hemodialysis, and in particular to an integrated device for automated disinfection of hemodialysis pipelines and waste liquid separation. Background Art

[0002] Hemodialysis is a renal replacement therapy for patients with acute and chronic renal failure. It involves draining blood from the body and passing it through a dialyzer composed of numerous hollow fibers. The blood and dialysate, which has a similar concentration to the body's, exchange substances within and outside the hollow fibers through diffusion, ultrafiltration, adsorption, and convection. This process removes metabolic waste, maintains electrolyte and acid-base balance, and simultaneously removes excess water from the body. The purified blood is then returned to the body. This entire process is called hemodialysis.

[0003] In actual hemodialysis, it is necessary to ensure a sterile environment for blood and dialysate pipelines to effectively avoid cross-infection during the dialysis process. However, existing hemodialysis pipelines can only transport blood or dialysate alone and cannot effectively sterilize and disinfect the pipelines. Usually, the pipelines need to be directly replaced to achieve comprehensive disinfection, and the sterilization efficiency is low. In view of this, we provide an integrated device for automated disinfection and waste liquid separation of hemodialysis pipelines. Summary of the Invention

[0004] In response to the above-mentioned shortcomings of the existing technology, the present invention provides an integrated device for automated disinfection of hemodialysis pipelines and waste liquid separation, which can effectively solve the problem of ensuring a sterile environment for blood and dialysate pipelines in existing hemodialysis, and effectively avoid cross-infection in the dialysis process.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Example:

[0036] Refer to the attached Figure 1-Figure 7 As shown in, an integrated device for automated disinfection and waste liquid separation of hemodialysis pipelines comprises a frame 100, a collecting box 110 is provided on one side of the lower portion of the frame 100 for collecting waste liquid; and a shell A300 and a shell B200 movably connected to the inner position of the frame 100, a mounting frame 600 is provided between the middle of the shell A300 and the shell B200, a dialysis membrane 630 is provided in the middle of the mounting frame 600, a liquid outlet pipe A310 is provided on the upper side of the shell A300, and a liquid inlet pipe A320 is provided on the lower side thereof, a liquid inlet pipe B210 is provided on the upper side of the shell B200, and a liquid outlet pipe B220 is provided on the lower side; specifically, in the present application, during actual use, the specific hemodialysis pipeline is connected to the arterial blood vessel of the external blood vessel through the provided liquid inlet pipe A310, and the blood after dialysis is completed can be input into the venous blood vessel of the dialysis patient through the provided liquid outlet pipe A320;

[0037] Correspondingly, the liquid inlet pipe B210 is connected to the input end of the dialysate, and the liquid outlet pipe B220 is connected to the collection box 110, which collects the used dialysate and the collected waste liquid. During the dialysis process, the flow direction of the corresponding blood is opposite to the flow direction of the dialysate to ensure the dialysis effect. In this application, in the dialysis link, the corresponding shell A300 and the shell B200 are overlapped, and the installation frame 600 for fixing the dialysis membrane 630 is also between the shell A300 and the middle part of the shell B200. On the one hand, it can ensure the sealing between the shell A300 and the shell B200. Secondly, the corresponding dialysis membrane 630 can dialyze impurities in the blood to complete the dialysis.

[0038] When dialysis is completed, the housing A300 and the housing B200, as well as the dialysis membrane 630 located in the middle of the housing A300 and the housing B200, need to be replaced. Therefore, in the present application, a disinfection solution is also included. Specifically, in the present application, a resisting rod 430 is fixedly mounted on the outer wall of the housing A300 and the housing B200. The end of the resisting rod 430 is fixedly mounted with a connecting block 420. An inclined surface A422 is provided on the upper side of the connecting block 420, and a moving block 400 movably connected to the inner position of the frame 100. The moving block 420 is fixedly mounted on the outer wall of the housing A300 and the housing B200. 00 is provided with an inclined surface B401 that slides with the inclined surface A422. On the outer wall of the movable block 400, two pipe fittings 410 are symmetrically provided in the vertical direction. One pipe fitting 410 is connected to the external dialysate, and the other pipe fitting 410 is connected to the external disinfectant. In the opposite position, one pipe fitting 410 is connected to the external patient's blood, and the other pipe fitting 410 is connected to the external disinfectant. In addition, a through hole is provided on the lower outer wall of the frame body 100 for discharging the disinfectant after cleaning.

[0039] When the shell A300 is separated from the shell B200, the corresponding resistance rods 430 fixedly connected to the shell A300 and the shell B200 will move away from each other. During this process, combined with the sliding fit between the inclined surface A422 and the inclined surface B401, it will drive the movable block 400 slidingly connected relative to the frame 100 to move vertically upward. During the dialysis link, the corresponding liquid outlet pipe A310 will remain connected with one of the pipe fittings 410. After the dialysis is completed, the corresponding movable block 400 will move upward. At this time, the pipe fitting 410 located at the lower side of the movable block 400 will remain connected with the liquid outlet pipe A310. It should be noted that at this time, the pipe fitting 410 will remain connected with the output end of the external water pump, and the water pump is used to inject a certain amount of disinfectant water into the cavity A303 and the cavity B201. In this way, effective disinfection of the hemodialysis pipeline is achieved.

[0040] As an embodiment, in the present application, regarding the method of adjusting the relative position between the shell A300 and the shell B200, the present application also includes a drive shaft 620 movably connected to the outer wall of the frame 100, and a drive block 610 is fixedly installed at the end of the drive shaft 620, and the drive block 610 is used to adjust the distance between the shell A300 and the shell B200. The end of the drive shaft 620 is fixedly connected to the output end of the external hydraulic cylinder, and the end of the drive shaft 620 extends into the frame 100 and is fixedly connected to the drive block 610, and the drive block 610 is fixedly connected to the mounting frame 600; the drive block 610 is a trapezoidal structure, and two inclined surfaces C611 are symmetrically provided on the outer wall of the drive block 610; it also includes a connecting block 540 fixedly installed on the outer walls of both sides of the shell A300 and the shell B200, and the two connecting blocks 540 away from the side of the drive block 610 are elastically connected by a spring 240, and the connecting block 540 close to the side of the drive block 610 is provided with an inclined surface D541. When the drive shaft 620 moves toward the side away from the frame 100, relative sliding occurs between the corresponding inclined surface C611 and the inclined surface D541, and drives the shell A300 and the shell B200 away from each other.

[0041] Specifically, in the present application, when hemodialysis is completed, the external hydraulic cylinder operates, driving the drive shaft 620 to move toward the side away from the frame 100. At this time, the drive block 610 fixedly installed at the end position of the drive shaft 620 will also move synchronously, and cooperate with the sliding cooperation relationship between the inclined surface C611 and the inclined surface D541. When the two slide relative to each other, the corresponding shell A300 will move away from the shell B200. It should be noted that, combined with the fixed connection relationship between the mounting frame 600 and the drive block 610, the corresponding fixed dialysis membrane 630 will also be pulled out from between the shell A300 and the shell B200. At this time, the edges of the cavity A303 and the cavity B201 are in a relatively separated state. After the disinfectant is injected into the frame 100, the corresponding cavity A303 and the inner wall of the cavity B201 can fully contact the disinfectant, thereby achieving comprehensive disinfection.

[0042] Regarding the disinfection scheme, in this application, in order to ensure the comprehensiveness of disinfection, it also includes a plurality of piston tubes 520 symmetrically arranged on the outer wall of the frame 100, and a piston rod 530 is fixedly installed on the outer wall of the connecting block 540. The piston rod 530 and the piston tube 520 are slidably fitted together. When the shell A300 and the shell B200 move away from each other, the corresponding piston rod 530 will slide in the piston tube 520 and squeeze the internal gas of the piston tube 520; and a box body 500 symmetrically fixedly installed on the outer walls on both sides of the frame 100, a rubber sheet 510 is arranged between the box body 500 and the middle part of the frame 100, and a chamber is formed between the rubber sheet 510 and the box body 500, and the box body 500 is connected to the inside of the piston tube 520 through the connecting tube.

[0043] As an embodiment, during the disinfection process, after the external pump body injects a certain amount of disinfectant water into the frame body 100, the amount of injected water needs to completely immerse the shell A300 and the shell B200. Correspondingly, in this application, a control valve is provided on the connecting pipe for connecting the box body 500 and the piston tube 520. When the disinfectant is injected, the control valve opens, and the corresponding gas enters the chamber between the box body 500 and the middle part of the rubber sheet 510. At this time, the rubber sheet 510 will move toward the inside of the frame body 100 and push the disinfectant in the internal position of the frame body 100, thereby increasing the fluidity of the disinfectant and thereby improving the disinfection effect.

[0044] Furthermore, in the application, in addition to the disinfection method of disinfection with disinfectant, it also includes a plurality of transverse grooves 301 that are provided on the housing A300 and the housing B200. The transverse grooves 301 are symmetrically arranged at the upper and lower sides of the mounting groove 304. A disinfection light strip 230 is fixedly installed in the transverse groove 301. The disinfection light strip 230 is electrically connected to the external power supply. It also includes a contact switch provided on the contact surface between the inclined surface C611 and the inclined surface D541. When the drive block 610 and the connecting block 540 slide relative to each other, the corresponding disinfection light strip 230 is powered on. Specifically, before disinfection, the liquid in the cavity A303 and the cavity B201 needs to be completely discharged. At this time, the disinfection light strip 230 provided at the upper and lower sides of the mounting groove 304 will achieve complete disinfection of the cavity A303 and the cavity B201.

[0045] Specifically, in the present application, a cavity A303 is provided inside the housing A300, and a cavity B201 is provided inside the housing B200; and a mounting groove 304 is provided on the overlapping surface of the housing A300 and the housing B200, and the mounting groove 304 is adapted to the cross-sectional dimensions of the mounting frame 600. The corresponding cavity A303 is a circulation space for the dialysate, and the corresponding cavity B201 is a circulation space for the patient's blood, and the dialysate and blood flow in opposite directions, thereby ensuring that the dialysis membrane 630 achieves efficient dialysis of the blood. In the present application, when the middle portions of the housing A300 and the housing B200 are overlapped, the corresponding mounting groove 304 is located between the middle portions of the housing A300 and the housing B200. When the mounting frame 600 is installed, the corresponding housing A300 and the housing B200 can maintain a stable sealing overlap, thereby ensuring sealing during the dialysis process and reducing pollution from the external environment.

[0046] Furthermore, in the dialysis process, in order to ensure the effect of dialysis, in addition to ensuring that the direction of blood flow is opposite to the direction of dialysate flow, in this application, an arc block 302 is fixedly connected to one side of the cavity A303, and the arc block 302 is arranged in an inclined direction from top to bottom toward the outside. In the actual dialysis process, when the dialysate enters the cavity A303, the dialysate at this time is at a faster flow rate, and its internal components are relatively stable, so as to facilitate subsequent sufficient component exchange with the blood. In this application, the upper side of the cavity A303 and the inner wall of the cavity A303 are closer to the dialysis membrane 630. In the vertical direction, with the flow direction of the dialysate, the flow rate of the dialysate decreases. At this time, combined with the dialysis membrane 630 with a sheet structure, sufficient dialysis of the blood can be achieved.

[0047] Refer to the attached Figure 2 As shown in , the present application also includes a solution for filtering the waste liquid in the collection box 110. First, a filter membrane is provided in the corresponding collection box 110, and the middle part of the top surface of the filter membrane is fixedly connected to the vertical plate 121 through the cylinder 120. In the present application, an arc-shaped surface 421 is provided on the lower side of the overlap block 420 fixedly connected to the outer wall of the shell A300; it also includes a vertical plate 121 slidably connected to the outer wall of the box body 500, and the upper end of the vertical plate 121 is arc-shaped, and the upper end of the vertical plate 121 slides with the arc-shaped surface 421. The lower end of the vertical plate 121 is connected to the filter membrane through the cylinder 120. The filter membrane is movably connected to the inside of the collection box 110, and the collection box 110 is connected to the liquid outlet pipe B220. When shell A300 is separated from shell B200, the arc surface 421 fixed at the lower side of the overlap block 420 will contact the arc surface at the upper end of the vertical plate 121 and slide relative to each other. At this time, the corresponding filter membrane is movably connected to the collection box 110. At this time, the waste liquid in the collection box 110 will be fully filtered by the filter membrane to ensure the efficiency of waste liquid filtration and separation.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
