Description

Technical Field

[0001] This utility model relates to the field of blood purification technology, and in particular to an integrated blood purification pipeline device. Background Technology

[0002] Continuous renal replacement therapy (CRRT), a novel blood purification technology, replaces the function of damaged kidneys through continuous blood purification therapy for 24 hours or similar duration daily. This technology encompasses various modes, including continuous arteriovenous / venous hemofiltration (CAVH / CVVH) and continuous arteriovenous / venous hemodialysis (CAVDH / CVVDH), and is considered one of the "three major life support technologies" for critically ill patients, along with mechanical ventilation and extracorporeal membrane oxygenation (ECMO). Continuous blood purification tubing is an essential consumable for CRRT treatment, and its connection method varies depending on the treatment mode.

[0003] Currently, the mainstream continuous blood purification equipment and tubing on the market primarily use a chuck-type assembly method. This method involves pre-assembling various bulk tubing components into a blister chuck, which is then assembled by the manufacturer and installed into the equipment by medical personnel. However, this traditional solution has significant drawbacks: firstly, the numerous and dispersed tubing components result in low integration, making them prone to detachment during transportation due to shaking, thus affecting product quality; secondly, when medical personnel open the bags, loose tubing components can easily fall to the ground, compromising sterility and significantly increasing the risk of infection.

[0004] Furthermore, the various treatment modes involve complex and dispersed tubing with intricate connections. Medical staff must spend extra time tracing the tubing routes, locating connectors, and following the instructions on the blood purification equipment to complete the installation. This not only reduces work efficiency but also extends patient preparation time. When switching treatment modes, tubing must be manually replaced, requiring medical staff to be familiar with the differences in tubing connections between different modes and to accurately distinguish similar connectors, demanding a high level of operational expertise.

[0005] To address the above problems, this utility model provides an integrated blood purification pipeline device to solve these issues. Utility Model Content

[0006] To address the problems of low integration, easy detachment during transportation, cumbersome operation and easy contamination, inconvenient treatment mode switching, and the single mode of existing integrated solutions in the existing continuous blood purification tubing equipment, this utility model provides a blood purification tubing integrated device with the advantages of high integration, diverse applicable treatment modes, small assembly workload, and simple operation.

[0007] To achieve the above objectives, the following technical solution is provided:

The flow channels include at least a first flow channel, a second flow channel, and a third flow channel, and each of the first, second, and third flow channels is equipped with a pressure monitoring device. The pipeline installation unit includes at least a first pipeline installation unit. The second flow channel and the first flow channel are used to complete the pre-pump to post-pump pipeline installation and coordination with their corresponding functional pumps. The third flow channel and the first pipeline installation unit are used to complete the pre-pump to post-pump pipeline installation and coordination with their corresponding functional pumps.

[0010] Furthermore, the flow channel also includes a fourth flow channel, and the pipeline installation unit also includes a second pipeline installation unit. The fourth flow channel and the second pipeline installation unit are used to complete the pipeline installation and coordination from the pump front to the pump back of their corresponding functional pumps.

[0011] Furthermore, the flow channel also includes a fifth flow channel and a sixth flow channel. The fifth and sixth flow channels are used to complete the installation and coordination of the pipeline from the pump front to the pump back for the corresponding functional pumps. Pressure monitoring devices are installed on both the fifth and sixth flow channels.

[0012] Furthermore, the flow channel also includes a seventh flow channel; the pipeline installation unit also includes a third pipeline installation unit on the same side as the seventh flow channel, the third pipeline installation unit and the seventh flow channel are used to complete the pipeline installation from the pump front to the pump back for the corresponding functional pump.

[0013] Furthermore, the pipeline installation unit also includes a fourth pipeline installation unit and a fifth pipeline installation unit, which are used to complete the installation and coordination of pipelines from before the pump to after the pump corresponding to its functional pump.

[0014] Furthermore, the pressure monitoring device includes a pressure monitoring connector and an elastic diaphragm. The pressure monitoring connector is located on the back of the integrated disk, and the elastic diaphragm is located in the cavity between the pressure monitoring connector and its corresponding flow channel, used to separate the gas end corresponding to the pressure monitoring connector from the liquid end corresponding to the flow channel.

[0015] Furthermore, the integrated panel has several perforated areas on it, allowing pipes to pass through to the back of the integrated panel.

[0016] Furthermore, the degassing tank assembly structure includes a degassing tank mounting chamber located below the integrated panel, and the degassing tank mounting chamber is respectively provided with a return line inlet connector and a return line outlet connector.

[0017] Furthermore, the integrated panel includes a base plate and side plates surrounding the base plate, with mounting structures for connecting blood purification equipment on the side plates; the degassing vessel assembly structure, several flow channels, and several pipeline installation units are all mounted on the base plate.

[0018] The beneficial effects of this utility model are as follows: This solution integrates the flow channels, pump tubes, and pipelines required for various treatment modes by setting up a degassing vessel assembly structure, several flow channels, and several pipeline placement units on an integrated panel. This facilitates transportation, prevents scattering during unpacking, and simplifies the assembly process due to its high degree of integration. Furthermore, the rational layout of the pump tubes reduces the use of pump tubes, which helps reduce the amount of blood circulating outside the body and minimizes the entry of fine polymer particles from the pump tubes into the bloodstream, thus reducing the likelihood of clotting. Operation is convenient, helping to reduce the time medical staff spend managing the pipelines and improving work efficiency. A pressure monitoring device is integrated into the flow channel, eliminating the need for external pressure monitoring equipment. Attached Figure Description

[0037] The following describes in detail a blood purification pipeline integrated device of this utility model with reference to embodiments.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a blood purification tubing integration device includes an integration panel 1. The integration panel 1 is provided with a degassing vessel assembly structure, several flow channels integrated into the integration panel for conveying fluid, and several tubing installation units. The functional structure of the tubing installation units can be a pump pipe fixing structure or presented in the form of flow channels. Each flow channel has a tubing connector at both ends. The flow channels include at least a first flow channel 2, a second flow channel 3, and a third flow channel 4. Each of the first flow channel 2, second flow channel 3, and third flow channel 4 is provided with a pressure monitoring device 8. The tubing installation unit includes at least a first tubing installation unit 6. The second flow channel 3 and the first flow channel 2 are used to complete the pre-pump to post-pump tubing installation and coordination with their corresponding functional pumps. The third flow channel 4 and the first tubing installation unit 6 are used to complete the pre-pump to post-pump tubing installation and coordination with their corresponding functional pumps.

[0039] This solution integrates a degassing vessel assembly structure, several flow channels, and several tubing placement units on the integrated panel 1. This allows for the adaptable integration of flow channels, tubing connection joints, and connectors for blood purification equipment required for various treatment modes, facilitating transportation, preventing detachment, and minimizing the risk of spillage during unpacking. Furthermore, it helps reduce the time medical staff spend managing tubing, improving work efficiency. The integrated pressure monitoring device 8 eliminates the need for external pressure monitoring equipment, demonstrating a high degree of integration.

[0040] The degassing vessel has a cavity structure, and its shape matches that of the degassing vessel used in blood purification equipment.

[0041] Existing contact-based pressure monitoring technologies rely on pressure transmission through the pipe wall, potentially causing localized compression and narrowing of the lumen. This narrowing leads to increased blood flow velocity and turbulence, intensifying friction between red blood cells, platelets, and the vessel wall. Downstream, a sudden drop in flow velocity creates a "blood stagnation zone," where platelets easily deposit and aggregate, initiating a coagulation cascade. Furthermore, contact-based pressure monitoring may lag behind actual pressure changes. When a slight blockage in the pipe causes a pressure increase, the sensor may fail to alarm in time, prolonging blood retention and allowing coagulation factors to fully activate, thus triggering coagulation. In this solution, if... Figure 5 , Figure 6As shown, the pressure monitoring device 8 includes a pressure monitoring connector 26 and an elastic diaphragm 27. The pressure monitoring connector 26 is located on the back of the integrated disk 1, and the elastic diaphragm 27 is located in the cavity between the pressure monitoring connector 26 and its corresponding flow channel, used to separate the gas end 45 corresponding to the pressure monitoring connector 26 from the liquid end 44 corresponding to the flow channel. The elastic diaphragm 27 acts as a physical barrier, completely separating the blood / drug solution (liquid end 44) ​​in the flow channel from the gas conduction path (gas end 45) of the pressure monitoring connector 26. The diaphragm transmits pressure only through deformation (liquid pressure → diaphragm deformation → gas end 45 pressure conduction), ensuring that the fluid is sealed within the pipeline, meeting the sterility and biocompatibility requirements of medical devices, and also possessing the advantages of sensitive dynamic response and accurate pressure transmission.

[0042] like Figure 6 , Figure 10 As shown, the first flow channel 2, the second flow channel 3, and the third flow channel 4 have openings on one side of the back of the integrated disk 1. The elastic diaphragm 27 covers the openings, and the pressure monitoring connector 26 is fastened to the openings and pressed onto the elastic diaphragm. Then, the pressure monitoring connector 26 is fixed to the integrated disk 1 by local ultrasonic welding. A sealing ring 39 is provided on the pressure monitoring connector 26, which plays a role in ensuring a seal after being connected to the pressure measuring pipeline.

[0043] One form of the piping installation unit is a connector fixing structure, such as a snap-fit. By fitting a fastener onto the pump pipe and engaging it with the snap-fit, the pump pipe can be installed on the integrated panel 1. Another form can be arranged as a flow channel. In order to save the space available on the integrated panel, in this embodiment, the piping installation unit is in the form of a snap-fit.

[0044] like Figure 1 , Figure 2 , Figure 12 As shown, the integrated tray 1 includes a base plate 35 and side plates 36 surrounding the base plate 35. The side plates 36 are equipped with a mounting structure 37 for the blood purification equipment panel 48. The mounting structure 37 is a locking block; the integrated tray slides into the mounting position of the blood purification equipment panel 48 via the locking block and is then locked in place, thus achieving installation. The degassing chamber assembly structure, several flow channels, and several tubing units are all integrated and installed on the base plate 35. Tubing components for different hemodialysis modes are installed on the integrated tray 1, and then the integrated tray 1 is installed on the hemodialysis equipment. The tubing components are then connected to the corresponding treatment mode's connecting tubing within the equipment. Figure 12 As shown, the pump body 47 on the device panel 48 is a peristaltic pump, which pumps fluid by alternately squeezing and releasing the tubing. Figure 8 , Figure 9As shown, the side plate 36 surrounds the base plate 35, and the edge of the base plate 35 is connected to the middle of the side plate 36, forming a receiving space on both the front and back of the base plate 35. The degassing tank assembly structure is visible on both the front and back sides of the base plate 35 with the base plate 35 as the plane of symmetry, as are the several flow channels. The degassing tank assembly structure, the several flow channels, the base plate 35, and the side plate 36 can be integrally injection molded.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 11 As shown, a reinforcing rib 38 connects the base plate 35 and the side plate 36. This serves two purposes: firstly, to improve the structural strength of the blood purification pipeline integration device; and secondly, to partition the various pipeline connection components on the base plate 35. To facilitate pipeline insertion, through holes can also be made in the reinforcing rib 35, which helps to organize the complex pipeline routes and make the product neat and orderly. The reinforcing rib 38 and the integrated plate 1 are integrally injection molded.

[0046] like Figure 11 As shown, there is a circular area in the lower left corner for attaching electronic tags 46, which are used in conjunction with the equipment for anti-counterfeiting identification.

[0047] Preferably, the integrated tray 1 has several hollow areas for the tubing to pass through to the back of the integrated tray 1. These hollow areas facilitate the arrangement of tubing on both the front and back of the integrated tray 1, improving tubing neatness, reducing pump tube length, helping to reduce extracorporeal blood circulation volume, and reducing blood retention time in the tubing, thereby improving the contact efficiency between blood and the filter and reducing the burden on the heart. Tube clamping structures 40 are provided on both the front and back of the integrated tray 1 to secure the tubing and prevent tubing components from scattering during product transportation or unpacking. In this embodiment, the first flow channel 2, the second flow channel 3, and the third flow channel 4 are arranged sequentially from top to bottom on the left side of the integrated tray 1. The first tubing placement unit 6 is located between the second flow channel 3 and the third flow channel 4, and a first hollow area 9 is provided between the second flow channel 3 and the third flow channel 4.
