Description

Technical Field

[0001] This utility model specifically relates to a waste fluid treatment mechanism for peritoneal dialysis machines, belonging to the field of medical equipment technology. Background Technology

[0002] In the medical field, peritoneal dialysis, as one of the important methods of renal replacement therapy, is widely used in the treatment of patients with chronic renal failure. During operation, peritoneal dialysis machines generate a large amount of waste fluid containing metabolic waste, toxins, and bacteria, which must be collected in a dedicated waste fluid container.

[0003] Currently, the disposal of waste fluid containers from peritoneal dialysis machines largely relies on manual operation. Operators must manually disassemble and transport the containers to a cleaning and disinfection area, where they are cleaned and disinfected through rinsing with water and soaking in chemical reagents. This method is not only labor-intensive and inefficient, but also carries the risk of cross-contamination from bacteria that may remain on the surface of the waste fluid containers during handling and cleaning. Furthermore, manual operation makes it difficult to ensure the uniformity and thoroughness of cleaning and disinfection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a waste liquid treatment mechanism for peritoneal dialysis machines, thereby achieving the integrated function of rinsing, suction, and disinfection.

[0005] A waste fluid treatment mechanism for a peritoneal dialysis machine includes a treatment tank, the interior of which is divided into a flushing chamber and a suction chamber by a partition. The treatment tank is characterized by: a suction pump and a pulse flushing pump installed on the upper part of the treatment tank; a suction pipe and a drain pipe communicating with the suction chamber; a flushing pipe and a water inlet pipe communicating with the flushing chamber; an input end of the suction pump connected to the suction pipe; an output end of the suction pump connected to the drain pipe; an input end of the pulse flushing pump connected to the water inlet pipe; an output end of the pulse flushing pump connected to the flushing pipe; an opening communicating with the flushing chamber on one side of the treatment tank; and a cover plate rotatably installed on the treatment tank for sealing the opening, with an ultraviolet lamp installed inside the cover plate.

[0006] Furthermore, the pump has an input pipe connected to its input end and an output pipe connected to its output end. The input pipe is connected to the suction pipe, and the output pipe is connected to the drain pipe.

[0007] Furthermore, the output end of the pulse flushing pump is connected to a supply pipe, and the end of the supply pipe away from the pulse flushing pump is connected to the flushing pipe.

[0008] Furthermore, a sampling tube is connected to the drain pipe, and a sampling switch is connected to the end of the sampling tube away from the drain pipe.

[0009] Furthermore, the cover plate is provided with a viewing window, and tempered glass is embedded inside the viewing window.

[0010] Furthermore, a rotating shaft is rotatably mounted on the processing box, a rotating frame is fixedly mounted on the rotating shaft, a rotating shaft is rotatably mounted on the rotating frame, and the cover plate is connected to the rotating shaft.

[0011] Furthermore, a ratchet is connected to one end of the rotating shaft, and a pawl adapted to the ratchet is rotatably mounted on the processing box.

[0012] Furthermore, a leaf spring is installed on the processing box, one end of which is connected to a pawl. In the initial state of the leaf spring, the pawl tends to rotate toward the ratchet.

[0013] Beneficial effects:

[0014] 1. This utility model achieves automatic rinsing of waste liquid tanks and automatic discharge of waste liquid through the coordinated work of components such as suction pump, pulse flushing pump, suction pipe, drain pipe, flushing pipe and water inlet pipe, which greatly reduces manual operation, reduces labor intensity and improves processing efficiency.

[0015] 2. In this invention, the ultraviolet lamp is installed inside the cover plate and can rotate to irradiate the waste liquid tank, ensuring comprehensive coverage of all surfaces. Compared to fixed irradiation methods, this effectively eliminates blind spots in disinfection, ensuring that bacteria, viruses, and other microorganisms remaining on the outer surface of the waste liquid tank are fully inactivated. Simultaneously, irradiation of the rinsing chamber kills bacteria adhering to its inner wall during rinsing, preventing the rinsing chamber from becoming a source of contamination and ensuring a clean cleaning and disinfection environment. Combined with the treatment box's division into a rinsing chamber and a suction chamber, and the rinsing action of the pulse rinsing pump and rinsing pipes, the disinfection efficiency and effectiveness are significantly improved, reducing the risk of cross-infection.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 As shown, a waste fluid treatment mechanism for a peritoneal dialysis machine includes a treatment box 1, which is internally divided into a flushing chamber 3 and a suction chamber 4 by a partition 2. A suction pump 5 and a pulse flushing pump 6 are installed on the upper part of the treatment box 1. The treatment box 1 is provided with a suction pipe 7 and a drain pipe 9 communicating with the suction chamber 4. The treatment box 1 is also provided with a flushing pipe 8 and a water inlet pipe 13 communicating with the flushing chamber 3. The input end of the suction pump 5 is connected to the suction pipe 7, and the output end of the suction pump 5 is connected to the drain pipe 9. The input end of the pulse flushing pump 6 is connected to the water inlet pipe 13, and the output end of the pulse flushing pump 6 is connected to the flushing pipe 8. An opening communicating with the flushing chamber 3 is opened on one side of the treatment box 1. A cover plate 12 for sealing the opening is rotatably installed on the treatment box 1. An ultraviolet lamp 24 is installed inside the cover plate 12.

[0025] Specifically, the treatment tank 1 is divided into a rinsing chamber 3 and a suction chamber 4 by a partition 2. During operation, the inlet pipe 13 is connected to a water source, and the pulse rinsing pump 6 flushes the external waste liquid tank with water through the rinsing pipe 8. The suction pump 5 draws the wastewater generated during rinsing into the suction chamber 4 through the suction pipe 7, and then discharges it through the drain pipe 9. After rinsing and suction are completed, the cover 12 is closed, and the waste liquid tank is disinfected using the ultraviolet lamp 24 inside the cover 12. This design achieves integrated treatment of waste liquid tank rinsing, suction, and disinfection. The separated chambers avoid mutual interference between rinsing water and waste liquid, ensuring the high efficiency of the treatment process. The ultraviolet lamp 24 disinfects in a closed environment, improving the disinfection effect and reducing the risk of cross-infection.

[0026] It should be noted that: in order to facilitate the installation of the suction pump 5 and the pulse flushing pump 6 on the treatment box 1, a hook is provided on the treatment box 1, and the suction pump 5 and the pulse flushing pump 6 are provided with hook grooves that are compatible with the hooks.

[0027] As a technical optimization of this utility model, the input end of the suction pump 5 is connected to the suction pipe 14, and its output end is connected to the discharge pipe 15. The suction pipe 14 is connected to the suction pipe 7, and the discharge pipe 15 is connected to the drain pipe 9.

[0028] Specifically, during the suction process, the waste liquid enters the suction pump 5 through the suction pipe 7 and the inlet pipe 14 in sequence, and is then discharged through the outlet pipe 15 and the drain pipe 9. The arrangement of the inlet pipe 14 and the outlet pipe 15 makes the connection between the suction pump 5 and the suction pipe 7 and the drain pipe 9 more flexible, which facilitates the installation and maintenance of the equipment, while ensuring the smoothness of waste liquid suction and discharge.

[0029] As a technical optimization of this utility model, the output end of the pulse flushing pump 6 is connected to the supply pipe 16, and the end of the supply pipe 16 away from the pulse flushing pump 6 is connected to the flushing pipe 8.

[0030] Specifically, the output end of the pulse flushing pump 6 is connected to the supply pipe 16, which delivers the water output by the pulse flushing pump 6 to the flushing pipe 8 to flush the waste liquid tank in the form of pulsed water flow. The supply pipe 16 ensures that the pulsed water flow generated by the pulse flushing pump 6 can be stably delivered to the flushing pipe 8, which enhances the flushing effect and removes stains and microorganisms from the surface of the waste liquid tank more effectively.

[0031] As a technical optimization of this utility model, a sampling tube 10 is connected to the drain pipe 9, and a sampling switch 11 is connected to the end of the sampling tube 10 away from the drain pipe 9.

[0032] Specifically, when it is necessary to test the discharged waste liquid, the sampling switch 11 is turned on, and part of the waste liquid will flow out through the sampling tube 10 for sampling, which facilitates real-time testing of the discharged waste liquid, timely understanding of the waste liquid treatment status, and provides data support for subsequent treatment operations, ensuring the safety and effectiveness of waste liquid treatment.

[0033] As a technical optimization of this utility model, a viewing window 23 is provided on the cover plate 12, and tempered glass is embedded inside the viewing window 23.

[0034] Specifically, during the rinsing and disinfection process, operators can observe the treatment status inside the treatment tank 1 and the waste liquid tank through the viewing window 23, which allows operators to monitor the treatment progress and effect in real time without having to frequently open the cover 12, reducing the possibility of external contamination. At the same time, the tempered glass ensures the strength and safety of the viewing window 23.

[0035] As a technical optimization of this utility model, a rotating shaft 17 is rotatably mounted on the processing box 1, a rotating frame 21 is fixedly mounted on the rotating shaft 17, a rotating shaft 22 is rotatably mounted on the rotating frame 21, and the cover plate 12 is connected to the rotating shaft 22.

[0036] Specifically, rotating the rotating shaft 17 can open or close the cover plate 12. This structural design makes the opening and closing of the cover plate 12 more flexible and stable, making it convenient for operators to place and remove the waste liquid tank before and after processing, thus improving the convenience of operation.

[0037] As a technical optimization of this utility model, one end of the rotating shaft 17 is connected to a ratchet 18, and a pawl 19 adapted to the ratchet 18 is rotatably installed on the processing box 1.

[0038] Specifically, when the cover plate 12 is closed, the pawl 19 engages with the ratchet 18, restricting the rotation shaft 17 from rotating in the opposite direction, thereby fixing the position of the cover plate 12, ensuring that the cover plate 12 remains closed during the disinfection process, preventing ultraviolet leakage, and avoiding accidental opening of the cover plate 12 due to external factors, thus ensuring the safety and effectiveness of the disinfection process.

[0039] As a technical optimization of this utility model, a leaf spring 20 is installed on the processing box 1. One end of the leaf spring 20 is connected to the pawl 19. In the initial state of the leaf spring 20, the pawl 19 has a tendency to rotate toward the ratchet 18.

[0040] Specifically, this allows the pawl 19 to mesh tightly with the ratchet 18, enhancing the reliability of the meshing between the pawl 19 and the ratchet 18, further ensuring the stability of the cover plate 12 position, and improving the overall operational safety of the equipment.

[0041] Working principle: When using the waste fluid treatment mechanism for peritoneal dialysis machines, first connect the inlet pipe 13 to an external water source. Place the waste fluid container after use of the peritoneal dialysis machine in a suitable position next to the treatment tank 1. At this time, the cover plate 12 is in the closed state, and the leaf spring 20 pushes the pawl 19 to engage with the ratchet 18 at one end of the rotating shaft 17, thus fixing the cover plate 12.

[0042] The pulse flushing pump 6 is started, and water is delivered to the flushing pipe 8 via the supply pipe 16. The flushing pipe 8 directly flushes the waste liquid tank with pulsed water flow, effectively removing residual waste liquid, stains, and some microorganisms from the surface of the waste liquid tank. During this process, the suction pump 5 works simultaneously, drawing the waste liquid tank and the wastewater generated during flushing into the suction chamber 4 through the intake pipe 14 and the suction pipe 7, and then discharging it through the discharge pipe 15 and the drain pipe 9. If it is necessary to sample and test the discharged waste liquid, the sampling switch 11 at the end of the sampling tube 10 connected to the drain pipe 9 can be opened to obtain a waste liquid sample.

[0043] After the rinsing and suction processes are completed, the pulse rinsing pump 6 and suction pump 5 are turned off, and the ultraviolet lamp 24 installed inside the cover plate 12 is turned on. In the enclosed environment, the ultraviolet lamp 24 rotates and irradiates the waste liquid tank, eliminating disinfection blind spots on the surface of the waste liquid tank and inactivating residual bacteria, viruses, and other microorganisms. At the same time, it irradiates the internal space of the treatment tank 1, including the area near the rinsing pipe 8, to kill any bacteria that may be present, preventing them from becoming a source of contamination and ensuring the cleanliness of the entire treatment environment. Operators can observe the disinfection status of the waste liquid tank in real time through the tempered glass in the viewing window 23 on the cover plate 12.

[0044] After the ultraviolet disinfection is completed, rotate the rotating shaft 17. At this time, the pawl 19 under the action of the leaf spring 20 is separated from the ratchet 18 at one end of the rotating shaft 17. The rotating shaft 17 drives the cover plate 12 to open through the rotating frame 21 and the rotating shaft 22, and the treated waste liquid tank can be taken out for subsequent use or storage, thus completing a complete peritoneal dialysis machine waste liquid tank treatment process.
