Description

Technical Field

[0001] The present invention relates to the technical field of blood purification, and in particular to a blood purification pipeline integrated device. Background Art

[0002] Continuous renal replacement therapy (CRRT) is a new blood purification technology that replaces damaged kidney function through continuous blood purification therapy for 24 hours or a similar duration daily. This technology encompasses multiple modes, including continuous arteriovenous / venovenous hemofiltration (CAVH / CVVH) and continuous arteriovenous / venovenous hemodialysis (CAVDH / CVVDH). Along with mechanical ventilation and extracorporeal membrane oxygenation, it is considered one of the "three major life support technologies" for critically ill patients. Continuous blood purification circuits are essential consumables for CRRT treatment, and their connection methods vary depending on the treatment mode.

[0003] Currently, the mainstream continuous blood purification equipment and tubing combination on the market is mainly chuck-type. This method pre-installs different bulk tubing into blister chucks, which are assembled by the manufacturer and then installed on the equipment by medical staff. However, this traditional solution has significant drawbacks: first, the number of tubing is large and the distribution is scattered, resulting in low integration. During transportation, tubing is easily detached due to shaking, affecting product quality; second, when medical staff open the bag, scattered tubing parts are easily scattered to the ground, destroying the sterile state and greatly increasing the risk of infection.

[0004] Furthermore, the different treatment modes involve complex and dispersed tubing, with complicated connections. Medical staff must spend extra time sorting out the tubing routes, locating connectors, and completing installation by following the blood purification equipment's prompts. This not only reduces work efficiency but also prolongs patient treatment 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, placing high demands on operational expertise.

[0005] In view of the above problems, the present invention provides a blood purification pipeline integrated device to solve the above problems. Summary of the Invention

[0006] In order to solve the problems of low integration, easy falling off during transportation, cumbersome operation and easy contamination, inconvenient switching of treatment modes, and the single mode of existing integrated solutions in the continuous blood purification pipeline equipment in the prior art, the present invention provides a blood purification pipeline integrated device with the advantages of high integration, diverse applicable treatment modes, small assembly workload and simple operation.

[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 pipeline installation unit are used to complete the pipeline installation from the front of the pump to the back of the pump with corresponding functions.

[0037] The blood purification pipeline integrated device of the present invention is described in detail below with reference to embodiments.

[0038] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a blood purification pipeline integrated device includes an integrated disk 1, on which is provided a degassing pot assembly structure, several flow channels integrated into the integrated disk for conveying fluids, and several pipeline placement units. The functional structure of the pipeline placement unit can be a pump tube fixing structure or presented in the form of a flow channel; pipeline joints are provided at both ends of each flow channel; the flow channels include at least a first flow channel 2, a second flow channel 3 and a third flow channel 4, and the first flow channel 2, the second flow channel 3 and the third flow channel 4 are each provided with a pressure monitoring device 8; the pipeline placement unit includes at least a first pipeline placement unit 6; the second flow channel 3 and the first flow channel 2 are used to complete the pipeline installation cooperation from the front of the pump to the back of the pump of the functional pump corresponding to them; the third flow channel 4 and the pipeline placement unit 6 are used to complete the pipeline installation cooperation from the front of the pump to the back of the pump of the functional pump corresponding to them.

[0039] This solution, by arranging a degassing pot assembly structure, several flow channels and several pipeline placement units on the integrated disk 1, can adaptively integrate the flow channels required for various treatment modes, the joints connecting the pipelines, and the joints connected to the blood purification equipment. This makes transportation convenient, and is not easy to fall off or scatter when the package is removed. In addition, it helps to reduce the time medical staff spend on sorting out the pipelines and improve work efficiency. The pressure monitoring device 8 is integrated in the flow channel, and there is no need for additional external pressure monitoring equipment, which has the advantage of high integration.

[0040] The assembly structure of the degassing pot is a cavity structure, and its shape matches the shape of the degassing pot used in blood purification equipment.

[0041] The contact-type pressure monitoring used in the existing technology needs to transmit pressure through the tube wall, which may cause local squeezing of the tube wall, resulting in stenosis of the lumen, faster blood flow velocity in the stenosis, forming turbulence, intensified friction between red blood cells, platelets and blood vessel walls, and a "blood retention zone" is formed in the downstream area due to the sudden drop in flow velocity. Platelets are prone to deposition and aggregation, initiating the coagulation cascade reaction. In addition, contact-type pressure monitoring may lag behind the actual pressure change. When the pipeline is slightly blocked and the pressure increases, the sensor fails to alarm in time, the blood retention time is prolonged, and the coagulation factors are fully activated, thereby inducing 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, and is 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 / medicine liquid (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 transmission), ensuring that the fluid is enclosed in the pipeline, meeting the sterility and biocompatibility requirements of medical equipment, and also has 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 are provided with openings on one side of the back of the integrated disk 1, the elastic diaphragm 27 covers the openings, the pressure monitoring connector 26 is snapped into the opening and pressed on the elastic diaphragm, and 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 sealing after being connected to the pressure measuring pipeline.

[0043] One form of the pipeline placement unit is a connector fixing structure, such as a snap fastener. By inserting the fastener onto the pump tube and engaging the fastener with the snap fastener, the pump tube can be installed on the integrated disk 1. Another form can be arranged in the form of a flow channel. To save space on the integrated disk, the pipeline placement unit in this embodiment is a snap fastener.

[0044] like Figure 1 、 Figure 2 、 Figure 12 As shown, the integrated disk 1 includes a bottom plate 35 and side plates 36 arranged around the bottom plate 35. The side plates 36 are provided with a mounting structure 37 for the blood purification equipment panel 48. The mounting structure 37 is a clamping block. The integrated disk slides into the mounting position of the blood purification equipment panel 48 through the clamping block and is fixed to achieve installation. The degassing pot assembly structure, several flow channels and several pipeline placement units are all integrated and installed on the bottom plate 35. The pipeline components under different hemodialysis modes are installed on the integrated disk 1, and then the integrated disk 1 is installed on the hemodialysis equipment. The pipeline components are connected to the connecting pipelines of the corresponding treatment mode in the equipment, as shown in FIG. Figure 12 As shown, the pump body 47 on the device panel 48 is a peristaltic pump that pumps fluid by alternately squeezing and releasing the pipeline. Figure 8 、 Figure 9As shown, side panels 36 surround the base plate 35, with the edges of the base plate 35 connected to the middle of the side panels 36, creating accommodation spaces on both the front and back sides of the base plate 35. The degassing pot assembly structure, with the base plate 35 as the plane of symmetry, is visible on both the front and back sides of the base plate 35, as are the flow channels. The degassing pot assembly structure, the flow channels, the base plate 35, and the side panels 36 can be integrally injection molded.

[0045] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 11 As shown, reinforcing ribs 38 are connected between the bottom plate 35 and the side plates 36. These ribs serve to enhance the structural strength of the integrated blood purification circuit assembly and to partition the various pipe connection components on the bottom plate 35. To facilitate the insertion of pipes, through-holes can be provided on the reinforcing ribs 35, facilitating the smoothing of complex pipe routing and maintaining a neat and orderly product. The reinforcing ribs 38 and the integrated tray 1 are integrally molded.

[0047] Preferably, the integrated disk 1 is provided with several hollow areas for the pipelines to pass through to the back of the integrated disk 1. The hollow areas facilitate the interlaced arrangement of the pipelines on the front and back of the integrated disk 1, which is conducive to the neatness of the pipelines, reduces the length of the pump tube, helps to reduce the amount of extracorporeal blood circulation, reduces the residence time of blood in the pipeline, thereby improving the contact efficiency between the blood and the filter and reducing the burden on the heart; a pipe clamping structure 40 is provided on the front and back of the integrated disk 1 to fix the pipeline to avoid the scattering of pipeline accessories when the product is transported or unpacked. In this embodiment, the first flow channel 2, the second flow channel 3, and the third flow channel 4 are arranged in sequence from top to bottom on the left side of the integrated disk 1. The first pipeline 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;

The back side of the fifth and sixth flow channels 18 and 19 has an opening, which is covered by an elastic diaphragm 27. The pressure monitoring connector 26 snaps into the opening and presses against the elastic diaphragm.

[0057] The existing blood purification pipeline integrated device can support fewer treatment modes. When switching treatment modes, the pipeline needs to be manually replaced, which increases the risk during the treatment process.
