Description

[0001] This application claims priority to Chinese Patent Application No. 202510183366.5, filed on February 18, 2025, entitled "A Panel Kit for a Blood Purification Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application belongs to the field of medical devices, and in particular relates to a panel kit for a blood purification device. Background Technology

[0003] Blood purification therapy is a treatment method that involves drawing the patient's blood outside the body and then using a filtration unit to remove pathogenic substances from the blood in order to purify the blood. The main treatment methods include hemodialysis, hemofiltration, hemodiafiltration, hemoperfusion, and plasma exchange.

[0004] In related technologies, blood purification therapy is typically achieved by connecting a blood purification device to the patient's blood vessels. Therefore, the blood purification device requires numerous tubing segments to deliver the patient's blood, replacement fluid, anticoagulants, etc. Furthermore, to ensure the safety of the blood returning to the patient, the tubing segments must be replaced after each use, and the large number of tubing segments makes installation quite challenging. Summary of the Invention

[0005] In a first aspect, embodiments of this application provide a panel kit for a blood purification device, comprising: The power panel and the monitoring panel are independent panels that can be independently and detachably installed onto the housing of the blood purification equipment; and, A tubing assembly for connecting the filter to a patient's blood vessel and a medical liquid container, respectively; The pipeline assembly includes at least two pump pipe sections, which are mounted on the power panel. When the pump pipe sections are adapted to the pump assembly of the blood purification device, the pump pipe sections are driven by the pump assembly to drive the flow of blood or medical fluid. The piping assembly further includes at least two monitoring segments, which are installed on the monitoring panel. The monitoring segments are used to monitor parameter information of the blood and / or the medical fluid, including at least a pressure parameter. At least one of the monitoring segments is provided with a first interface. When the first interface is connected to a second interface of the blood purification device, the monitoring segment is used for the blood purification device to monitor the parameter information. During the installation of the monitoring panel to the device housing, the first interface is fixedly positioned relative to the monitoring panel.

[0006] Secondly, embodiments of this application also provide a panel kit for a blood purification device, comprising: The power panel and the monitoring panel are independent panels that can be independently and detachably installed onto the housing of the blood purification equipment; and, A tubing assembly for connecting the filter to a patient's blood vessel and a medical liquid container, respectively; The pipeline assembly includes at least two pump pipe sections, which are mounted on the power panel. When the pump pipe sections are adapted to the pump assembly of the blood purification device, the pump pipe sections are driven by the pump assembly to drive the flow of blood or medical fluid. The piping assembly further includes at least two monitoring segments mounted on the monitoring panel. These monitoring segments are used to monitor parameter information of the blood and / or the medical fluid, including at least a pressure parameter. At least one monitoring segment has a first interface. When the first interface is connected to a second interface of the blood purification device, the monitoring segment is used for the blood purification device to monitor the parameter information. The first interface is movable relative to the monitoring panel, allowing the user to connect the first interface to the second interface by operating the first interface.

[0007] In this embodiment, on the one hand, by setting at least two pump pipe segments on the power panel, the user can assist in the installation of at least two pump pipe segments through the installation action of the power panel, thereby reducing the installation difficulty and the probability of incorrect installation. On the other hand, by setting at least two monitoring pipe segments on the monitoring panel, the installation action of the monitoring panel can assist in the installation of at least two monitoring pipe segments, thereby reducing the installation difficulty and the probability of incorrect installation. Furthermore, during the installation of the monitoring panel to the equipment housing, when the first interface is fixed relative to the monitoring panel, the first interface can be installed accordingly after the panel is in place, thus saving the subsequent step of manually assembling the first interface and the second interface. When the first interface is movable relative to the monitoring panel, after the monitoring panel is in place, the user can easily manually connect the first interface and the second interface, avoiding the difficulty of installing the first interface in one go, thereby reducing the installation difficulty of the panel kit. Therefore, this embodiment also allows the panel kit to have the advantages of easy installation and high accuracy of parameter component detection results. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] Please refer to Figure 1 and Figure 2This application provides a panel kit 100 for a blood purification device. The panel kit 100 includes a power panel 11, a monitoring panel 12, and a tubing assembly 13. The power panel 11 and the monitoring panel 12 are independently and detachably mounted to the device housing 21 of the blood purification device 200. The tubing assembly 13 is used to connect the filter 300 to the patient's blood vessels and a medical liquid container, respectively.

[0024] It should be noted that in this embodiment, the power panel 11 and the monitoring panel 12 can be disassembled and assembled independently of each other. That is to say, the power panel 11 and the monitoring panel 12 are independent panels and can be disassembled and assembled independently.

[0025] The piping assembly 13 includes at least two pump tubing segments 131, which are mounted on the power panel 11. When the pump tubing segments 131 are adapted to the pump assembly 22 of the blood purification device 200, the pump tubing segments 131 are driven by the pump assembly 22 to drive the flow of blood or medical fluid. Therefore, by setting at least two pump tubing segments 131 on the power panel 11, the user can assist in the installation of at least two pump tubing segments 131 through the installation action of the power panel 11, thereby reducing the installation difficulty and the probability of incorrect installation.

[0026] The piping assembly 13 also includes at least two monitoring tubing segments 132, which are mounted on the monitoring panel 12. These monitoring tubing segments 132 are used to monitor parameters of blood and / or medical fluids, including at least pressure parameters. Therefore, by mounting at least two monitoring tubing segments 132 on the monitoring panel 12, the installation of at least two pump tubing segments 131 can be assisted by the installation action of the monitoring panel 12, thereby reducing the difficulty of installing the at least two pump tubing segments 131 and the probability of incorrect installation.

[0027] At least one monitoring tube segment 132 is provided with a first interface 1321. When the first interface 1321 is connected to the second interface 23 of the blood purification device 200, the monitoring tube segment 132 is used to provide the blood purification device 200 with monitoring parameter information.

[0028] During the installation of the monitoring panel 12 onto the equipment housing 21, the first interface 1321 is fixed relative to the monitoring panel 12; or, the first interface 1321 is movably positioned relative to the monitoring panel 12.

[0029] When the first interface 1321 is fixed relative to the monitoring panel 12, since the first interface 1321 is fixed relative to the monitoring panel 12 during the installation of the monitoring panel 12 to the device housing 21, the first interface 1321 can also be installed in place after the monitoring panel 12 is installed. This saves the step of manually assembling the first interface 1321 with the second interface 23. In addition, when the blood purification device 200 is working, it can also prevent the first interface 1321 from moving relative to the monitoring panel 12 and becoming loose, thereby improving the accuracy and reliability of the detection results of the blood purification device 200.

[0030] When the first interface 1321 is set to active relative to the monitoring panel 12, this active setting allows the user to connect the first interface 1321 to the second interface 23 by operating the first interface 1321.

[0031] For example, after the monitoring panel 12 is installed, the user can easily connect the first interface 1321 and the second interface 23 manually to avoid misalignment and sealing between the first interface 1321 and the second interface 23.

[0032] In one embodiment, during actual manufacturing, form tolerances are inevitable for each part, and positional tolerances are inevitable between parts during assembly. To address this, by movably configuring the first interface 1321 relative to the monitoring panel 12, after the monitoring panel 12 is installed, the user can manually connect the first interface 1321 to the second interface 23. This eliminates the need for costly and complex manufacturing processes to ensure that the accumulated form and positional tolerances of the first interface 1321, the monitoring panel 12, and the blood purification device 200 are within acceptable limits. Ultimately, this reduces the manufacturing difficulty of the monitoring panel 12 and the difficulty of installing it onto the device housing 21.

[0033] Furthermore, during the actual assembly of the panel kit 100 onto the blood purification device 200, when there are too many parts that need to be installed at once, such as the monitoring panel 12 and the first interface 1321, it is difficult to ensure that all these parts can be installed synchronously. Therefore, after the monitoring panel 12 is installed, the user can manually connect the first interface 1321 to the second interface 23, which makes the installation of the panel kit 100 simpler and more convenient.

[0034] Optionally, when the first interface 1321 is movable relative to the monitoring panel 12, during the installation of the monitoring panel 12 onto the device housing 21, the first interface 1321 is movable relative to the monitoring panel 12 to compensate for the tolerances of at least one of the first interface 1321, the monitoring panel 12, and the blood purification device 200. Furthermore, by making the first interface 1321 movable relative to the monitoring panel 12, accumulated dimensional and positional tolerances during the manufacturing and assembly of the components in the first interface 1321, the monitoring panel 12, and the blood purification device 200 can be prevented from causing the second interface 23 to fail to connect with the first interface 1321. Simultaneously, compared to a movable setting that allows the user to connect the first interface 1321 and the second interface 23 by operating the first interface 1321, in this embodiment, by controlling the first interface 1321 to move only within a small range to compensate for tolerances, excessive movement of the first interface 1321 relative to the monitoring panel 12 can be avoided, thereby preventing the second interface 23 from colliding with the first interface 1321 and failing to be properly installed. Of course, by avoiding excessive movement of the first interface 1321 relative to the monitoring panel 12, it is also possible to prevent the first interface 1321 from shaking and becoming loose during the operation of the blood purification device 200, thereby improving the accuracy and reliability of the detection results of the blood purification device 200.

[0035] The above is an overall description of the technical solutions of the embodiments of this application.

[0036] In some embodiments, the pump pipe section 131 includes a first flexible conduit. When the pump pipe section 131 is adapted to the pump assembly 22, the first flexible conduit abuts against the pump head of the pump assembly 22, so that the rotation of the pump head can drive the first flexible conduit to be wound around the pump head. Therefore, during the installation of the panel kit 100, only the first flexible conduit needs to contact the pump head of the pump assembly 22, without the user having to manually wind the pump pipe section 131 around the pump head of the pump assembly 22, thus making the installation of the pump pipe section 131 simpler and more convenient.

[0037] For example, pump assembly 22 may include a peristaltic pump. When the first flexible tubing comes into contact with the pump head of the peristaltic pump, the peristaltic pump first drives the first flexible tubing to wrap around the pump head, and then the peristaltic pump continues to squeeze the first flexible tubing by rotating the pump head, thereby driving the flow of blood or medical fluid in the pump section 131.

[0038] Optionally, the pump section 131 includes a first flexible conduit. When the pump section 131 is adapted to the pump assembly 22, the first flexible conduit is routed to the pump head of the pump assembly 22, so that the rotation of the pump head directly drives the flow of the corresponding blood or medical fluid in the first flexible conduit.

[0039] Understandably, when the pump pipe section 131 is adapted to the pump assembly 22, whether the first flexible pipe is directly wound around the pump head of the pump assembly 22 or the pump assembly 22 needs to work so that the first flexible pipe is wound around the pump head of the pump assembly 22, it means that after the power panel 11 is installed on the equipment housing 21, the user does not need to connect the pump pipe section 131 to the pump assembly 22, thus making the installation of the power panel 11 simpler.

[0040] The technical solution of this application embodiment will be introduced below in conjunction with the installation method of the power panel 11.

[0041] In the first installation method of the power panel 11, when the power panel 11 is installed in the first preset position of the device housing 21, the power panel 11 can be driven by the blood purification device 200 to move to the first target position, thereby making the pump tube section 131 compatible with the pump assembly 22.

[0042] Furthermore, for the installation of the panel kit 100, the user only needs to install the power panel 11 to the first preset position of the device housing 21, and then the blood purification device 200 will automatically drive the power panel 11 to the first target position to achieve automatic installation of the power panel 11, making the installation of the panel kit 100 simpler.

[0043] Please combine Figure 1 and Figure 3 In some embodiments, the power panel 11 is provided with a first connecting part 111, which is used to connect to a first drive mechanism 24 on the device housing 21 so that the first drive mechanism 24 can drive the power panel 11 to move from a first preset position to a first target position.

[0044] The first connecting part 111 can be connected to the first driving mechanism 24 by means of snap-fit, screw-fit or magnetic fixation, etc., and this application embodiment does not limit this.

[0045] Taking the first connecting part 111 as an example, it can be fixedly engaged with the first driving mechanism 24. The first driving mechanism 24 can be provided with a first claw 241, which is fixedly engaged with the first connecting part 111.

[0046] Correspondingly, the first connecting portion 111 may include a first locking hole, and the first locking claw 241 may engage with the first locking hole. Of course, the first locking claw 241 may also include at least two first locking arms, and the first connecting portion 111 may be a protruding structure on the power panel 11, so that the first connecting portion 111 can be engaged between the two first locking arms. This application embodiment does not limit this.

[0047] In some embodiments, whether the power panel 11 is installed at the first preset position and / or the first target position can be determined by the first position detection mechanism 25 on the blood purification device 200. Furthermore, the position of the power panel 11 can be accurately detected by the first position detection mechanism 25, thereby determining the overall position of the panel assembly 100.

[0048] Therefore, the blood purification device 200 can determine whether the power panel 11 is properly installed when installed in the first preset position based on the detection result of the first position detection mechanism 25, thereby determining whether to drive the power panel 11 from the first preset position to the first target position via the first drive mechanism 24. Furthermore, after the blood purification device 200 drives the power panel 11 from the first preset position to the first target position via the first drive mechanism 24, the blood purification device 200 can also determine whether the power panel 11 is properly installed based on the detection result of the first position detection mechanism 25, thereby avoiding abnormal installation of the power panel 11.

[0049] In some embodiments, when the power panel 11 is installed at a first preset position and / or a first target position, the power panel 11 blocks or contacts the first position detection mechanism 25, thereby enabling the first position detection mechanism 25 to detect the position of the power panel 11.

[0050] For example, the first position detection mechanism 25 may include photoelectric sensors such as infrared ranging sensors, laser ranging sensors, and photoelectric gates, so that the first position detection mechanism 25 can detect the position of the power panel 11 by detecting the distance of the power panel 11, whether the power panel 11 blocks the corresponding photoelectric gate, etc.

[0051] Optionally, the first position detection mechanism 25 may also include a pressure sensor to detect the position of the power panel 11 by the pressure applied to the first position detection mechanism 25 when the power panel 11 is installed in the first preset position and / or the first target position.

[0052] Of course, in some other embodiments, the first position detection mechanism 25 may also include limit switches, Hall sensors, proximity switches, etc., and this application embodiment does not limit this.

[0053] It is also understood that when the first position detection mechanism 25 is used to detect whether the power panel 11 is installed in the first preset position and the first target position, the first position detection mechanism 25 may include at least two first sensors, at least one first sensor is used to detect whether the power panel 11 is installed in the first preset position, and at least another first sensor is used to detect whether the power panel 11 is installed in the first target position.

[0054] The above is an introduction to the first installation method of the panel kit 100 in the embodiments of this application. The second installation method of the panel kit 100 in the embodiments of this application will be described below.

[0055] In the second installation method of the power panel 11, the panel kit 100 can be manually installed to place the power panel 11 into the first target position and simultaneously adapt the pump pipe section 131 to the pump assembly 22. Therefore, after the power panel 11 is installed into the first target position, the user does not need to manually install the pump pipe section 131 to the pump head, thus reducing the difficulty for the user when installing the panel kit 100.

[0056] Correspondingly, whether the power panel 11 is installed in the first target position can be determined by the first position detection mechanism 25 on the blood purification device 200. Furthermore, the position of the power panel 11 can be accurately detected by the first position detection mechanism 25, thereby determining the overall position of the panel assembly 100.

[0057] The specific structure of the first position detection mechanism 25 will not be described in detail here.

[0058] In some embodiments, the power panel 11 may be provided with a first connecting portion 111, which is used to connect with the equipment housing 21 so that the power panel 11 can be detachably installed at a first target position.

[0059] For example, a first claw 241 may be fixedly provided on the device housing 21. The specific structure of the first claw 241 and the first connecting part 111 will not be described in detail here.

[0060] The above is a description of the second installation method of the panel kit 100 in the embodiments of this application. The technical solution of the embodiments of this application will be further described below in conjunction with the monitoring panel 12 in the embodiments of this application.

[0061] In the first installation method of the monitoring panel 12, the panel kit 100 allows the monitoring panel 12 to be manually installed to the second target position on the device housing 21, simultaneously connecting the first interface 1321 to the second interface 23. With the first interface 1321 and the second interface 23 connected, the monitoring tube segment 132 is used to provide the blood purification device 200 with monitoring parameter information. This reduces the steps required for independently installing the first interface 1321 and prevents users from incorrectly installing the first interface 1321 during manual installation, thereby improving the accuracy of the first interface 1321 installation.

[0062] It should be noted that the panel kit 100 allows the monitoring panel 12 to be installed at the second target position on the device housing 21 by manual installation, simultaneously connecting the first interface 1321 and the second interface 23. In other words, by installing the monitoring panel 12 at the second target position, the user can simultaneously connect the first interface 1321 and the second interface 23. During this process, the installation of the monitoring panel 12 at the second target position and the connection of the first interface 1321 and the second interface 23 can be completed simultaneously, or there can be a certain time difference. For example, when the first interface 1321 is movable relative to the monitoring panel 12, the monitoring panel 12 may continue to move a certain distance after the first interface 1321 is connected to the second interface 23 before being installed at the second target position on the device housing 21. This embodiment does not limit this.

[0063] In the second installation method of the monitoring panel 12, when the monitoring panel 12 is installed at the second target position of the device housing 21, the second interface 23 can extend to connect with the first interface 1321. When the first interface 1321 and the second interface 23 are connected, the monitoring tube segment 132 is used to provide the device housing 21 with monitoring parameter information. Therefore, the user only needs to simply install the monitoring panel 12 at the second target position of the device housing 21, and the second interface 23 on the blood purification device 200 can extend to connect with the first interface 1321 of the monitoring tube segment 132. This eliminates the need for the user to manually connect the second interface 23 and the first interface 1321 after installing the monitoring panel 12 at the second target position of the device housing 21, making the installation of the panel kit 100 much simpler.

[0064] In some embodiments, when the monitoring panel 12 is mounted in a second preset position on the device housing 21, the device housing 21 can drive the monitoring panel 12 to move to a second target position.

[0065] Optionally, the user may directly install the monitoring panel 12 on the second target position of the device housing 21, but this embodiment does not limit this.

[0066] In the third installation method of the monitoring panel 12, when the monitoring panel 12 is installed in the second preset position of the device housing 21, the blood purification device 200 can drive the monitoring panel 12 to move to the second target position, so that the first interface 1321 and the second interface 23 are fixedly connected. When the first interface 1321 and the second interface 23 are connected, the monitoring tube segment 132 is used for the blood purification device 200 to monitor parameter information. Therefore, for the installation of the panel kit 100, the user only needs to install the monitoring panel 12 in the second preset position of the device housing 21, and then the blood purification device 200 automatically drives the monitoring panel 12 to the first target position to realize the automatic installation of the monitoring panel 12, so as to simplify the installation of the panel kit 100.

[0067] In the fourth installation method of the monitoring panel 12, the first interface 1321 is movably set relative to the monitoring panel 12. When the monitoring panel 12 is installed at the second target position of the device housing 21, the first interface 1321 can be manually operated to connect the first interface 1321 and the second interface 23. When the second interface 23 is connected to the first interface 1321, the monitoring tube section 132 is used to supply the blood purification device 200 with monitoring parameter information.

[0068] After the monitoring panel 12 is installed, the user can easily connect the first interface 1321 and the second interface 23 manually to avoid misalignment and sealing between the first interface 1321 and the second interface 23.

[0069] In one embodiment, during actual manufacturing, form tolerances are inevitable for each part, and positional tolerances are inevitable between the parts during assembly. Therefore, after the monitoring panel 12 is installed to the second target position, the user can manually connect the first interface 1321 and the second interface 23. This eliminates the need for costly and complex manufacturing processes to ensure that the accumulated form and positional tolerances of the first interface 1321, monitoring panel 12, and blood purification device 200 are within acceptable limits, thus achieving one-time installation of the first interface 1321 and monitoring panel 12. Ultimately, this reduces the manufacturing difficulty of the panel kit 100 and the difficulty of installing the panel kit 100 into the device housing 21.

[0070] Furthermore, during the actual assembly of the panel kit 100 onto the blood purification device 200, when there are too many parts that need to be installed at once, such as the monitoring panel 12 and the first interface 1321, it is difficult to ensure that all these parts can be installed synchronously. Therefore, after the monitoring panel 12 is installed, the user can manually connect the first interface 1321 to the second interface 23, which makes the installation of the panel kit 100 simpler and more convenient.

[0071] In one embodiment, the connection between the first interface 1321 and the second interface 23 can be a sealed connection between the first interface 1321 and the second interface 23.

[0072] It is also understood that in the fourth installation method of the monitoring panel 12, the user can manually install the monitoring panel 12 to the second preset position and then the blood purification device 200 can automatically drive the monitoring panel 12 to the second target position to complete the installation, or the user can directly install the monitoring panel 12 to the second target position to complete the installation. This application embodiment does not limit this.

[0073] In some embodiments, the first interface 1321 and the second interface 23 can be connected by screwing, snapping, plugging, or other methods. Therefore, when the monitoring panel 12 is installed at the second target position, the first interface 1321 can be manually connected to the second interface 23 by tightening, pressing, or plugging the first interface 1321. This application does not limit this specific method.

[0074] For example, the first interface 1321 is provided with a knob. When the monitoring panel 12 is installed in the second target position, the first interface 1321 can be connected to the second interface 23 by the user turning the knob.

[0075] The above is a general introduction to the four installation methods of the monitoring panel 12 in the embodiments of this application.

[0076] In some embodiments, when the monitoring panel 12 is in the second preset position, the first interface 1321 is not connected to the second interface 23 on the device housing 21. Furthermore, when the monitoring panel 12 is in the second preset position, a certain gap can be reserved between the first interface 1321 and the second interface 23 so that when the monitoring panel 12 moves toward the second target position, the first interface 1321 can move toward the second interface 23 accordingly.

[0077] Furthermore, when the user needs to replace the panel kit 100 on the device housing 21 (i.e., when the panel kit 100 needs to be removed from the device housing 21), the device housing 21 can drive the power panel 11 to move from the second target position to the second preset position, thereby separating the first interface 1321 and the second interface 23, so that the user can more easily remove the panel kit 100 from the device housing 21.

[0078] Please combine Figure 1 and Figure 4In some embodiments, whether the monitoring panel 12 is installed at the second preset position and / or the second target position can be determined by the second position detection mechanism 26 on the blood purification device 200.

[0079] Therefore, the blood purification device 200 can determine whether the monitoring panel 12 is properly installed when it is installed in the second preset position based on the detection result of the second position detection mechanism 26, thereby determining whether to drive the monitoring panel 12 from the second preset position to the second target position; and, after the blood purification device 200 drives the power panel 11 from the second preset position to the second target position, the blood purification device 200 can also determine whether the monitoring panel 12 is properly installed based on the detection result of the second position detection mechanism 26.

[0080] In some embodiments, when the monitoring panel 12 is installed at the second preset position and / or the second target position, the monitoring panel 12 blocks or contacts the second position detection mechanism 26, thereby enabling the second position detection mechanism 26 to detect the position of the monitoring panel 12.

[0081] For example, the second position detection mechanism 26 may include photoelectric sensors such as infrared ranging sensors, laser ranging sensors, photoelectric gates, etc., so that the second position detection mechanism 26 can detect the position of the monitoring panel 12 by detecting the distance of the monitoring panel 12, whether the monitoring panel 12 blocks the corresponding photoelectric gate, etc.

[0082] Optionally, the second position detection mechanism 26 may also include a pressure sensor to detect the position of the monitoring panel 12 by monitoring the pressure applied to the second position detection mechanism 26 when the monitoring panel 12 is installed at the second target position.

[0083] Of course, in some other embodiments, the second position detection mechanism 26 may also include limit switches, Hall sensors, proximity switches, etc., and this application embodiment does not limit this.

[0084] It is also understandable that in the first installation method of the monitoring panel 12, the second position detection mechanism 26 on the blood purification device 200 can be used only to detect whether the monitoring panel 12 is located at the second target position, that is, whether the monitoring panel 12 is installed at the second target position can be detected by the second position detection mechanism 26 on the blood purification device 200.

[0085] It is understood that when the second position detection mechanism 26 is used to detect whether the monitoring panel 12 is installed in the second preset position and the second target position, the second position detection mechanism 26 may include at least two second sensors, at least one second sensor for detecting whether the monitoring panel 12 is installed in the second preset position, and at least another second sensor for detecting whether the monitoring panel 12 is installed in the second target position.

[0086] In some embodiments, the monitoring panel 12 is provided with a second connection portion 121, which is used to connect to the second drive mechanism 27 of the blood purification device 200 so that the second drive mechanism 27 can drive the monitoring panel 12 to move from a second preset position to a second target position.

[0087] For example, the second drive mechanism 27 is provided with a second claw 271, which can drive the second claw 271 to move. The second claw 271 is engaged and fixed with the second connecting part 121.

[0088] For example, the second connecting portion 121 may include a second latching hole, and the second latching claw 271 may be latched into the second latching hole. Of course, the second latching claw 271 may also include at least two second latching arms, and the second connecting portion 121 may be a protruding structure on the monitoring panel 12, so that the second connecting portion 121 can be latched between the two second latching arms. This application embodiment does not limit this.

[0089] It is also understood that the second claw 271 can be fixedly installed on the device housing 21. Correspondingly, the blood purification device 200 does not have a second drive mechanism 27, so the user can directly install the monitoring panel 12 to the second target position. This application embodiment does not limit this.

[0090] The technical solutions of the embodiments of this application will be further described below in conjunction with some other structures of the monitoring panel 12.

[0091] In some embodiments, the first interface 1321 is non-detachably connected to the corresponding monitoring tube segment 132. For example, the first interface 1321 and the corresponding monitoring tube segment 132 can be connected by means of bonding, integral molding, fusion welding, welding, etc., so as to avoid the first interface 1321 from becoming loose or even falling off, which would lead to inaccurate test results of the blood purification device 200.

[0092] Optionally, in some other embodiments, the first interface 1321 is detachably connected to the corresponding monitoring tube segment 132. For example, the first interface 1321 and the corresponding monitoring tube segment 132 are connected by means of screwing, snap-fitting, magnetic fixation, etc., so as to replace the appropriate first interface 1321 according to the model change of the second interface 23 of the blood purification device 200.

[0093] In some embodiments, the first interface 1321 is connected to the corresponding monitoring pipe segment 132 via a connector. The connector may be a Luer connector or other types of connectors, and this application embodiment does not limit this.

[0094] In some embodiments, the monitoring tube segment 132 is non-detachably connected to the monitoring panel 12. For example, the monitoring tube segment 132 and the monitoring panel 12 can be connected by means of bonding, integral molding, fusion welding, welding, etc., so as to avoid the monitoring tube segment 132 from becoming loose or even falling off, which would lead to inaccurate test results of the blood purification device 200.

[0095] Optionally, the monitoring tube segment 132 and the monitoring panel 12 can also be detachably connected. For example, the monitoring tube segment 132 and the monitoring panel 12 can be connected by screwing, snapping, magnetic fixation, etc., so as to replace the appropriate monitoring tube segment 132 or monitoring panel 12 according to the changes in the blood purification equipment 200.

[0096] In some embodiments, the flow path connecting the pump section 131 and the monitoring section 132 is a flexible hose.

[0097] For example, the piping assembly 13 also includes a second flexible piping, which connects at least one pump segment 131 and at least one monitoring segment 132.

[0098] Understandably, when the pump assembly 22 in the device housing 21 drives the pump tubing 131, the pump assembly 22 will not only cause the power panel 11 to vibrate but also pull on the pump tubing 131. Therefore, based on the separation of the power panel 11 and the monitoring panel 12 to avoid the vibration of the power panel 11 being transmitted to the monitoring panel 12, when the pump tubing 131 is pulled, the second flexible tubing can adaptively deform to prevent the pump tubing 131 from pulling on the connected monitoring tubing 132. This avoids the first interface 1321 from being loosened due to interference from the connected second flexible tubing and / or the monitoring panel 12, ultimately improving the accuracy of the blood purification device 200's test results.

[0099] Please continue to refer to this. Figure 5In some embodiments, at least one monitoring section 132 includes a pressure monitoring module 133, which includes a fluid section 1331, a gas section 1332, a diaphragm 1333, and a first interface 1321. A fluid-side cavity defined at least partially by the fluid section 1331 and a gas-side cavity defined at least partially by the gas section 1332 are separated by the diaphragm 1333. The fluid-side cavity is used for the flow of blood or medical fluid. The first interface 1321 communicates with the gas-side cavity. When the first interface 1321 is connected to a second interface 23, the monitoring section 132 is used by the device housing 21 to monitor the pressure parameters of the blood or medical fluid flowing through the fluid-side cavity.

[0100] Furthermore, when blood or medical fluid flows through the fluid side cavity, the blood or medical fluid will squeeze the diaphragm 1333, resulting in a change in the gas pressure in the gas side cavity. Then, the second interface 23 on the device housing 21 can monitor the gas pressure in the gas side cavity by docking with the first interface 1321, thereby monitoring the pressure parameters of the corresponding blood or medical fluid. This way, the second interface 23 does not need to come into contact with the corresponding blood or medical fluid, thus avoiding contamination of the blood or medical fluid.

[0101] Of course, in some other embodiments, at least one monitoring tube segment 132 may be adapted to a contact pressure sensor on the blood purification device 200. Thus, the contact pressure sensor on the device housing 21 can directly abut against the diaphragm 1333 to monitor the pressure parameters of the corresponding blood or medical fluid, which is not limited in this embodiment.

[0102] In some embodiments, at least two monitoring tube segments 132 are provided with a first interface 1321. When the first interface 1321 is connected to the second interface 23, the monitoring tube segment 132 is used for the blood purification device 200 to monitor pressure parameters. Furthermore, at least two first interfaces 1321 used for monitoring pressure parameters can be connected through the monitoring panel 12, making the installation of the panel kit 100 more convenient.

[0103] In some embodiments, filter 300 is used to filter blood flowing through pump section 131.

[0104] The filter 300 may be mounted on the blood purification device 200. After the panel assembly 100 is installed onto the device housing 21, the panel assembly 100 is then connected to the filter 300 on the blood purification device 200. Alternatively, the filter 300 may be mounted on the panel assembly 100, and the filter 300 may be fixed to the device housing 21 during the installation of the panel assembly 100 onto the device housing 21. This embodiment of the application does not limit this approach.

[0105] like Figure 4As shown, in some embodiments, when the first interface 1321 is connected to the second interface 23, the monitoring tube segment 132 is used by the blood purification device 200 to monitor the pressure parameters of the corresponding blood or medical fluid. At least two monitoring tube segments 132 also include a blood leakage monitoring tube segment 1322, which works in conjunction with the blood leakage monitoring module on the blood purification device 200 to monitor whether blood has permeated from one side of the filter membrane of the filter 300 to the other side. Furthermore, the monitoring panel 12 allows for the connection of at least one first interface 1321 for monitoring pressure parameters and the installation of the blood leakage monitoring tube segment 1322, making the installation of the panel kit 100 more convenient.

[0106] Please continue to refer to this. Figure 6 In some embodiments, the monitoring section 132 further includes a secondary membrane pressure monitoring section 1323, which is used to connect the blood output end of one filter 300 and the blood input end of another filter 300, and is used to monitor the pressure parameters of the blood.

[0107] For example, the tubing assembly 13 may also include a connecting flow path 13401, which is connected to the blood output end of one filter 300 and the blood input end of another filter 300, respectively, and the secondary membrane pressure monitoring tubing segment 1323 is disposed in the connecting flow path 13401.

[0108] Please continue to refer to this. Figure 7 In some embodiments, pump section 131 includes waste hydraulic pump section 1311. Piping assembly 13 also includes waste fluid flow path 13402, the output end of which is connected to the input end of waste hydraulic pump section 1311, and the input end of waste fluid flow path 13402 is used to connect to the medical fluid output end of filter 300. Monitoring section 132 also includes waste hydraulic monitoring section 1324, which is disposed in waste fluid flow path 13402 and used to monitor the pressure parameters of the medical fluid.

[0109] Therefore, when pump assembly 22 is operating, the medical fluid in filter 300 can flow along waste fluid flow path 13402 to waste hydraulic pump section 1311, and then through waste hydraulic monitoring section 1324. This allows waste hydraulic monitoring section 1324 to monitor the pressure parameters of the medical fluid discharged from filter 300 (hereinafter referred to as waste hydraulic pressure). Furthermore, by monitoring waste hydraulic pressure, it can be determined whether the filter membrane of filter 300 is clogged.

[0110] It should be noted that, compared to placing the waste hydraulic monitoring pipe section 1324 downstream of the waste hydraulic pump pipe section 1311, this embodiment places the waste hydraulic monitoring pipe section 1324 between the waste hydraulic pump pipe section 1311 and the filter 300. This can prevent other faults downstream of the waste hydraulic pump pipe section 1311 from interfering with the waste hydraulic monitoring pipe section 1324 monitoring whether the filter membrane of the filter 300 is blocked.

[0111] In some embodiments, the piping assembly 13 further includes a collection flow path 13403, the input end of which is connected to the output end of the waste hydraulic pump section 1311, and the output end of which is connected to a medical fluid collection container or a secondary membrane pressure monitoring section 1323. Thus, the medical fluid in the filter 300 can flow sequentially along the waste fluid flow path 13402, the waste hydraulic pump section 1311, and the collection flow path 13403 before flowing into the medical fluid collection container or the secondary membrane pressure monitoring section 1323.

[0112] In some embodiments, the monitoring section 132 further includes a blood leakage monitoring section 1322, which is disposed in the waste liquid flow path 13402 or the collection flow path 13403. When the blood leakage monitoring section 1322 is adapted to the blood leakage monitoring module on the device housing 21, the blood leakage monitoring section 1322 is used for the blood leakage monitoring module to monitor whether blood on one side of the filter membrane of the filter 300 has permeated to the other side.

[0113] For example, the blood leakage monitoring module on the device housing 21 may include a photoelectric sensor, such as a color sensor, to determine the presence of blood components by monitoring the color of the medical liquid discharged from the filter 300.

[0114] Correspondingly, the blood leakage monitoring tube section 1322 can be made of light-shielding material in at least part of its area to avoid ambient light affecting the detection results of the blood leakage monitoring module.

[0115] Of course, the blood leakage monitoring module can also be any other module used to detect blood components, and this application embodiment does not limit this.

[0116] It is also understood that the input end of the blood leakage monitoring tube segment 1322 can face downwards, so that the medical fluid flows through the blood leakage monitoring tube segment 1322 from bottom to top, thereby avoiding the accumulation of air bubbles when the medical fluid flows from top to bottom through the blood leakage monitoring tube segment 1322, which would affect the detection results of the blood leakage monitoring module. Of course, in some other embodiments, the input end of the blood leakage monitoring tube segment 1322 can also face other directions, and this application embodiment does not limit this.

[0117] Similarly, at least one of the input ends of the monitoring tube segment 132 can face downwards so that the corresponding medical liquid or blood flows from bottom to top through the monitoring tube segment 132, thereby preventing air bubbles from accumulating in the monitoring tube segment 132 and affecting the test results.

[0118] Optionally, in some other embodiments, the panel assembly 100 includes a waste liquid branch for connection to the medical fluid output end of the filter 300. The waste liquid branch is provided with a blood leakage monitoring section 1322, through which the medical fluid flowing out of the filter 300 can pass. The blood purification device 200 also includes a blood leakage monitoring module, which can monitor whether blood has permeated from one side of the filter membrane of the filter 300 to the other side through the blood leakage monitoring section 1322.

[0119] For example, the waste liquid branch includes a waste liquid flow path 13402 and a collection flow path 13403. Therefore, the blood leakage monitoring tube segment 1322 can be located in either the waste liquid flow path 13402 or the collection flow path 13403; this embodiment does not limit the specific location.

[0120] In some embodiments, the waste liquid branch can allow the medical liquid flowing out of the filter 300 to flow from bottom to top through the blood leakage monitoring tube section 1322, thereby preventing air bubbles from accumulating in the blood leakage monitoring tube section 1322 and affecting the detection results.

[0121] It is also understood that the blood leakage monitoring tube segment 1322 can be set on the monitoring panel 12, thus serving as one of the monitoring tube segments 132; the blood leakage monitoring tube segment 1322 may also not be set on the monitoring panel 12, for example, the blood leakage monitoring tube segment 1322 may be set between the power panel 11 and the monitoring panel 12, and this application embodiment does not limit this.

[0122] For example, the blood leakage monitoring section 1322 can be set in the waste liquid flow path 13402 and located between the input end of the waste hydraulic pump section 1311 and the output end of the waste hydraulic monitoring section 1324.

[0123] Furthermore, on the one hand, it avoids the need to reserve a large space on the monitoring panel 12 to install the blood leakage monitoring tube segment 1322, thus facilitating the miniaturization design of the monitoring panel 12; on the other hand, it can also reduce the number of monitoring tube segments 132 on the monitoring panel 12, so that the tubing of the panel kit 100 does not need to be bent multiple times on the monitoring panel 12 to construct a large number of monitoring tube segments 132, thereby not only reducing the manufacturing difficulty of the panel kit 100, but also making the corresponding blood or medical fluid flow more smoothly in the panel kit 100.

[0124] In addition, when the input end of the waste hydraulic fluid monitoring pipe section 1324 is also facing downwards, the input end of the blood leakage monitoring pipe section 1322 can also face downwards to connect to the output end of the waste hydraulic fluid monitoring pipe section 1324 which is facing upwards. This avoids the accumulation of air bubbles when the medical fluid flows from top to bottom through the blood leakage monitoring pipe section 1322, which would affect the detection results of the blood leakage monitoring module.

[0125] Please continue to refer to this. Figure 8 In some embodiments, pump segment 131 includes blood pump segment 1312. The tubing assembly 13 also includes a blood drainage path 13404, a blood pumping path 13405, and a blood return path 13406. The input end of blood drainage path 13404 is connected to the blood drainage point of the patient's blood vessel, and the output end of blood drainage path 13404 is connected to the input end of blood pump segment 1312. The input end of blood pumping path 13405 is connected to the output end of blood pump segment 1312, and the output end of blood pumping path 13405 is used to connect to the blood input end of filter 300. The input end of blood return path 13406 is used to connect to the blood output end of filter 300, and the output end of blood return path 13406 is used to connect to the blood return point of the patient's blood vessel.

[0126] Thus, during the operation of the blood purification device 200, when the pump assembly 22 of the device housing 21 is working, the blood pump tubing 1312 drives blood from the blood draw point of the patient's blood vessel to flow sequentially through the blood draw path 13404, the blood pump tubing 1312, the blood pumping path 13405, the filter 300, and the blood return path 13406, and then flows back to the patient's blood vessel from the blood return point, thereby realizing extracorporeal blood circulation therapy for the patient.

[0127] In some embodiments, the monitoring section 132 includes a blood pressure monitoring section 1325, which is disposed in the blood flow path 13404 and is used to monitor blood pressure parameters.

[0128] Therefore, the blood pressure monitoring section 1325 can be used to monitor the pressure parameters of blood drawn from the patient's blood vessels (hereinafter referred to as blood pressure). Specifically, when the pump assembly 22 is working, the blood pump section 1312 can drive blood from the patient's blood vessels into the blood flow path 13404, and then, as the blood flows along the blood flow path 13404, it will flow through the blood pressure monitoring section 1325, thereby enabling the blood pressure monitoring section 1325 to detect the blood pressure. Thus, the blood purification device 200 can determine whether blood is being drawn normally from the patient's blood vessels by monitoring the blood pressure.

[0129] In some embodiments, the monitoring section 132 further includes a pre-filter pressure monitoring section 1326, which is disposed in the blood flow path 13405 and is used to monitor blood pressure parameters.

[0130] Therefore, the filter pre-pressure monitoring section 1326 can be used to monitor the pressure parameters of blood flowing into the filter 300 from the pump section 131 (hereinafter referred to as filter pre-pressure). Furthermore, by monitoring the filter pre-pressure, it can be determined whether blood can flow normally into the filter 300. For example, when the filter pre-pressure is too high, it may indicate that there is a blockage or clotting in the filter 300.

[0131] In some embodiments, at least two monitoring panels 12 are provided, with each panel 12 being separately arranged so that each panel 12 can be independently installed and removed. Each monitoring panel 12 has at least two different types of a blood leakage monitoring tube section 1322, a blood pressure monitoring tube section 1325, a filter pre-pressure monitoring tube section 1326, and a waste hydraulic pressure monitoring tube section 1324. Thus, by using at least two monitoring panels 12, the panel assembly 100 can be adapted to the installation requirements of more different types of equipment housings 21.

[0132] For example, one monitoring panel 12 may be provided with a blood pressure monitoring tube section 1325 and a filter pre-pressure monitoring tube section 1326, and another monitoring panel 12 may be provided with a blood leakage monitoring tube section 1322 and a waste hydraulic pressure monitoring tube section 1324. This application embodiment does not limit this.

[0133] When the monitoring section 132 also includes a secondary membrane pressure monitoring section 1323, the number of monitoring panels 12 can be at least two, with each monitoring panel 12 being separately arranged so that each monitoring panel 12 can be independently installed and removed. Each monitoring panel 12 is equipped with at least two different types of the following: a blood leakage monitoring section 1322, a blood pressure monitoring section 1325, a filter pre-pressure monitoring section 1326, a waste hydraulic pressure monitoring section 1324, and a secondary membrane pressure monitoring section 1323. Thus, by using at least two panel kits 100, the panel kits 100 can be adapted to the installation requirements of more different types of equipment housings 21.

[0134] Please continue to refer to this. Figure 9 In some embodiments, the tubing assembly 13 further includes an injection flow path 13407, the input end of which is connected to an anticoagulant injection pump, and the output end of which is connected to a blood drainage flow path 13404 or a blood pumping flow path 13405. Thus, the anticoagulant injection pump on the blood purification device 200 can inject anticoagulant drugs into the blood in the blood drainage flow path 13404 or the blood pumping flow path 13405 through the injection flow path 13407, thereby preventing blood clotting in the blood in the blood drainage flow path 13404 or the blood pumping flow path 13405.

[0135] Anticoagulant drugs may include heparin, citrate, etc., and this application does not limit the specific drugs used.

[0136] It is also understandable that when the injection flow path 13407 is connected to the blood flow path 13405, it can, to some extent, prevent the pump assembly 22 from generating a large negative pressure in the blood flow path 13404 during operation, which would draw out the anticoagulant from the anticoagulant injection pump.

[0137] In some embodiments, the pump tubing 131 further includes a pre-pump tubing 1315, and the tubing assembly 13 includes a first inlet flow path 13408 and a second inlet flow path 13409. The first inlet flow path 13408, the pre-pump tubing 1315, and the second inlet flow path 13409 are connected sequentially. The input end of the first inlet flow path 13408 is at least used to connect to an anticoagulant drug supply container, and the output end of the second inlet flow path 13409 is connected to the blood drainage flow path 13404, the blood pumping flow path 13405, or the blood return flow path 13406. Thus, the device housing 21 can drive the pre-pump tubing 1315 of the blood pump via the pump assembly 22, so that the anticoagulant in the anticoagulant supply container flows sequentially through the first inlet flow path 13408, the pre-pump tubing 1315 of the blood pump, and the second inlet flow path 13409 into the blood drainage flow path 13404, the blood pumping flow path 13405, or the blood return flow path 13406, so as to avoid blood clotting in the blood drainage flow path 13404, the blood pumping flow path 13405, or the blood return flow path 13406.

[0138] It is understandable that when the tubing assembly 13 is simultaneously equipped with an injection flow path 13407, a first inlet flow path 13408, a pre-pump tubing section 1315, and a second inlet flow path 13409, the anticoagulant injection pump connected to the injection flow path 13407 and the anticoagulant supply container connected to the first inlet flow path 13408 can be used to supply different anticoagulant drugs. For example, the anticoagulant injection pump can be used to supply heparin, and the anticoagulant supply container can be used to supply citrate, to meet the different anticoagulant requirements during the extracorporeal blood purification process.

[0139] Please continue to refer to this. Figure 10 In some embodiments, the pump section 131 includes a dialysate pump section 1313, and the piping assembly 13 further includes a third inlet flow path 13410 and a fourth inlet flow path 13411. The third inlet flow path 13410, the dialysate pump section 1313 and the fourth inlet flow path 13411 are connected sequentially. The input end of the third inlet flow path 13410 is used to connect to the dialysate supply container, and the output end of the fourth inlet flow path 13411 is used to connect to the medical fluid input end of the filter 300.

[0140] Therefore, when the pump assembly 22 on the device housing 21 is working, the pump assembly 22 can drive the dialysate in the dialysate supply container through the dialysate pump pipe section 1313 to flow into the filter 300 in sequence through the third inlet flow path 13410, the dialysate pump pipe section 1313, the fourth inlet flow path 13411, and the medical liquid input end of the filter 300.

[0141] In some embodiments, the pump section 131 further includes a replacement fluid pump section 1314, and the piping assembly 13 further includes a fifth inlet flow path 13412 and a sixth inlet flow path 13413. The fifth inlet flow path 13412, the replacement fluid pump section 1314 and the sixth inlet flow path 13413 are connected sequentially. The input end of the fifth inlet flow path 13412 is used to connect to the replacement fluid supply container, and the output end of the sixth inlet flow path 13413 is connected to the blood drainage flow path 13404, the blood pumping flow path 13405 or the blood return flow path 13406.

[0142] Thus, when the pump assembly 22 on the device housing 21 is working, the pump assembly 22 can drive the replacement fluid in the replacement fluid supply container through the replacement fluid pump pipe section 1314 to flow into the blood drainage path 13404, the blood pumping path 13405, or the blood return path 13406 in sequence through the fifth inlet flow path 13412, the replacement fluid pump pipe section 1314, and the sixth inlet flow path 13413.

[0143] The replacement fluid may include commercially available replacement fluids, such as online replacement fluids produced online by hemodialysis filtration machines and manually prepared replacement fluids, etc., and this application does not limit this.

[0144] In some embodiments, the panel assembly 100 further includes a heating panel 14 for removable mounting to the heating area of ​​the device housing 21. The piping assembly 13 includes a heating container 13414 and a liquid outlet path 13415, the liquid outlet path 13415 communicating with the output end of the heating container 13414. The heating container 13414 is mounted on the heating panel 14 for mounting to the heating area via the heating panel 14, allowing the heating device of the blood purification device 200 to heat the blood and / or medical fluid within the piping assembly 13. This satisfies the heating requirements of the blood and / or medical fluid. For example, the medical fluid can be heated to prevent excessively low-temperature medical fluid from affecting the blood, such as causing discomfort due to excessively low-temperature medical fluid returning to the body.

[0145] It is understood that the heating container 13414 may include coil-type heating containers, bladder-type heating containers, bottle-type heating containers, and bag-type heating containers, etc., and the embodiments of this application do not limit this.

[0146] In some embodiments, when the pump section 131 includes a dialysate pump section 1313, the heating container 13414 includes a first heating container 13421, the input end of the first heating container 13421 is connected to the output end of the fourth inlet flow path 13411, the outlet flow path 13415 connected to the first heating container 13421 includes a first outlet flow path 13416 and a second outlet flow path 13417, the first outlet flow path 13416 is connected to the blood return flow path 13406, and the second outlet flow path 13417 is used to connect to the medical liquid input end of the filter 300.

[0147] Therefore, in actual use, the input end of the third fluid inlet flow path 13410 can be connected to either a dialysis fluid supply container or a replacement fluid supply container to meet the diverse usage needs of the blood purification equipment 200.

[0148] For example, when the input end of the third inlet flow path 13410 is connected to the dialysate supply container, the first outlet flow path 13416 can be disconnected and the second outlet flow path 13417 can be connected by the first pipeline switching device 28 of the blood purification device 200. This allows the dialysate in the dialysate supply container to flow into the filter 300 after passing through the third inlet flow path 13410, the dialysate pump section 1313, the fourth inlet flow path 13411, the first heating container 13421, the second outlet flow path 13417, and the medical liquid input end of the filter 300.

[0149] Alternatively, when the input end of the third inlet flow path 13410 is connected to the replacement fluid supply container, the first outlet flow path 13416 can be connected and the second outlet flow path 13417 can be disconnected by the first pipeline switching device 28 of the blood purification device 200. This allows the replacement fluid in the replacement fluid supply container to flow into the blood return flow path 13406 after passing through the third inlet flow path 13410, the dialysate pump section 1313, the fourth inlet flow path 13411, the first heating container 13421, and the first outlet flow path 13416 in sequence.

[0150] In some embodiments, when the pump section 131 includes a displacement fluid pump section 1314, the heating container 13414 includes a second heating container 13422, the input end of the second heating container 13422 is connected to the output end of the sixth inlet flow path 13413, and the outlet flow path 13415 connected to the second heating container 13422 includes a first outlet flow path 13416 and a third outlet flow path 13418, the first outlet flow path 13416 is connected to the blood return flow path 13406, and the third outlet flow path 13418 is connected to the blood drainage flow path 13404 or the blood pumping flow path 13405.

[0151] Therefore, in actual use, the replacement fluid in the second heating container 13422 can selectively flow into the blood return path 13406, the blood drainage path 13404, or the blood pumping path 13405.

[0152] For example, the second pipeline switching device 29 of the blood purification device 200 can control the first outlet flow path 13416 to be connected and the third outlet flow path 13418 to be disconnected, so that the replacement fluid in the replacement fluid supply container flows to the return blood flow path 13406 after passing through the fifth inlet flow path 13412, the replacement fluid pump section 1314, the sixth inlet flow path 13413, the second heating container 13422 and the first outlet flow path 13416 in sequence, thereby realizing the injection of replacement fluid into the blood filtered by the filter 300.

[0153] Alternatively, the second pipeline switching device 29 of the blood purification device 200 can control the first outlet flow path 13416 to be disconnected and the third outlet flow path 13418 to be connected, so that the replacement fluid in the replacement fluid supply container flows through the fifth inlet flow path 13412, the replacement fluid pump pipe section 1314, the sixth inlet flow path 13413, the second heating container 13422 and the third outlet flow path 13418 in sequence to the blood draw flow path 13404 or the blood pump flow path 13405, thereby realizing the injection of replacement fluid into the blood that has not been filtered by the filter 300.

[0154] In some embodiments, the power panel 11 and the monitoring panel 12 are both separately disposed from the heating panel 14, so that the heating panel 14 can be independently assembled and disassembled relative to the power panel 11 and the monitoring panel 12.

[0155] Please continue to refer to this. Figure 11 In some embodiments, the output end of the first fluid outlet path 13416 may be connected to the blood drainage path 13404 or the blood pumping path 13405, the output end of the second fluid outlet path 13417 may be connected to the medical fluid input end of the filter 300, and the output end of the third fluid outlet path 13418 may be connected to the blood return path 13406.

[0156] Therefore, the replacement fluid in the replacement fluid supply container can be selectively injected into the blood flow path 13404 or the blood pumping flow path 13405 through the first outlet flow path 13416, or injected into the return flow path 13406 through the third outlet flow path. Furthermore, the input end of the third inlet flow path 13410 can be selectively connected to the dialysate supply container and injected into the filter 300 through the second outlet flow path 13417, or the input end of the third inlet flow path 13410 can be selectively connected to the replacement fluid supply container and injected into the blood flow path 13404 or the blood pumping flow path 13405 through the first outlet flow path 13416.

[0157] In some embodiments, the panel assembly 100 may not include the heating panel 14 and the heating container 13414. For example, the output end of the fourth liquid inlet flow path 13411 is connected to the input end of the first liquid outlet flow path 13416 and the input end of the second liquid outlet flow path 13417 via a T-connector or the like, and the output end of the sixth liquid inlet flow path 13413 is connected to the input end of the first liquid outlet flow path 13416 and the input end of the third liquid outlet flow path 13418 via a T-connector or the like.

[0158] At this time, the input terminals of the first liquid outlet flow path 13416, the second liquid outlet flow path 13417, and the third liquid outlet flow path 13418 can be installed on the power panel 11.

[0159] In some embodiments, the blood return flow path 13406 includes a degassing vessel 13419 and a degassing vessel monitoring unit 13420. The degassing vessel monitoring unit 13420 is connected to the degassing vessel 13419. When the degassing vessel monitoring unit 13420 is connected to the degassing vessel monitoring interface on the blood purification device 200, the degassing vessel monitoring unit 13420 is used by the blood purification device 200 to monitor the pressure inside the degassing vessel 13419. For example, the degassing vessel monitoring unit 13420 may include a Luer connector.

[0160] In some embodiments, the tubing assembly 13 further includes an electrostatic discharge unit 135, which works in conjunction with the blood purification device 200 to release static electricity from the tubing assembly 13. It is understood that static electricity may also be generated when the pump assembly 22 drives the pump tubing section 131 to move. Releasing the static electricity through the electrostatic discharge unit 135 can prevent interference with other simultaneously used devices, such as an electrocardiogram monitor.

[0161] In some embodiments, at least one of the power panel 11 and the monitoring panel 12 is provided with an electrostatic discharge unit 135. By integrating the electrostatic discharge unit 135 into the corresponding power panel 11 and / or monitoring panel 12, the electrostatic discharge unit 135 can be adapted to the blood purification device 200 through the synchronous installation of the corresponding power panel 11 and / or monitoring panel 12, thereby facilitating the installation of the panel kit 100.

[0162] Of course, in some other embodiments, the electrostatic discharge unit 135 may not be disposed on the power panel 11 or the monitoring panel 12, and this application embodiment does not limit this.

[0163] In some embodiments, the blood purification device 200 is provided with a conductive element, and an electrostatic discharge unit 135 is used to connect to the conductive element to release static electricity. For example, the electrostatic discharge unit 135 can form an electrical connection by contacting the conductive element, thereby grounding through the conductive element.

[0164] In some embodiments, a portion of a section of the conduit assembly 13 is made of a conductive material to form an electrostatic discharge unit 135. Of course, the electrostatic discharge unit 135 can also be a conductive unit connected to the conduit assembly 13, and this application embodiment does not limit this.

[0165] In some embodiments, the pump pipe section 131 is arc-shaped. Furthermore, the arc-shaped structure makes it easier for the pump pipe section 131 to be routed around to the pump head of the pump assembly 22.

[0166] In some embodiments, the openings formed at both ends of the pump tube segment 131 face the outer periphery of the power panel 11, thereby facilitating the connection of both ends of the pump tube segment 131 to other corresponding flow paths in the panel assembly 100 by having both ends of the pump tube segment 131 facing outward.

[0167] Optionally, at least the openings formed at both ends of a portion of the pump pipe section 131 face the inner periphery of the power panel 11, but this embodiment does not limit this.

[0168] Please continue to refer to this. Figure 12 In some embodiments, the power panel 11 includes adjacent first regions 112 and second regions 113, with the first region 112 located on one side of the second region 113 in a horizontal direction. The pump tubing 131 includes a blood pump tubing 1312 and multiple medical fluid pump tubing sections 1316. When the blood pump tubing 1312 is adapted to the pump assembly 22, it drives blood flow under the drive of the pump assembly 22. When the medical fluid pump tubing section 1316 is adapted to the pump assembly 22, it drives medical fluid flow under the drive of the pump assembly 22. One medical fluid pump tubing section 1316 and the blood pump tubing section 1312 are arranged generally vertically in the first region 112, and all other medical fluid pump tubing sections 1316 are arranged generally vertically in the second region 113. Thus, arranging the pump tubing sections 131 in two columns allows for full utilization of the space on the power panel 11.

[0169] The first region 112 is located on one side of the second region 113 along the horizontal direction. It can be that the upper end of the first region 112 is flush with the upper end of the second region 113, and the lower end of the first region 112 is flush with the lower end of the second region 113.

[0170] The first region 112 is located on one side of the second region 113 along the horizontal direction. Alternatively, the upper end of the first region 112 may be higher than the upper end of the second region 113. In this case, the lower end of the first region 112 may be lower than the lower end of the second region 113, or the lower end of the first region 112 may be higher than the lower end of the second region 113, or the lower end of the first region 112 may be flush with the lower end of the second region 113.

[0171] The first region 112 is located on one side of the second region 113 along the horizontal direction. Alternatively, the upper end of the first region 112 may be lower than the upper end of the second region 113. In this case, the lower end of the first region 112 may be lower than the lower end of the second region 113, or the lower end of the first region 112 may be higher than the lower end of the second region 113, or the lower end of the first region 112 may be flush with the lower end of the second region 113.

[0172] That is to say, in the embodiments of this application, the first region 112 is located on one side of the second region 113 along the horizontal direction. It is not necessary for the upper end of the first region 112 to be flush with the upper end of the second region 113, and the lower end of the first region 112 to be flush with the lower end of the second region 113.

[0173] In some embodiments, the first region 112 is located on one side of the second region 113 along the horizontal direction. This can be that at least half of the first region 112 along the vertical direction is directly opposite the second region 113 along the horizontal direction, and / or at least half of the second region 113 along the vertical direction is directly opposite the first region 112 along the horizontal direction.

[0174] In some embodiments, when the medical fluid pump tubing segment 1316 is adapted to the pump assembly 22, one of the medical fluid pump tubing segment 1316 located in the first region 112 and the medical fluid pump tubing segment 1316 located at the lowermost side of the second region 113 is used to drive the flow of anticoagulant drugs driven by the pump assembly 22, and the other is used to drive the flow of medical fluid out of the filter 300 driven by the pump assembly 22. Alternatively, when the medical fluid pump tubing segment 1316 is adapted to the pump assembly 22, one of the medical fluid pump tubing segment 1316 located in the first region 112 and the medical fluid pump tubing segment 1316 located in the middle of the second region 113 is used to drive the flow of anticoagulant drugs driven by the pump assembly 22, and the other is used to drive the flow of medical fluid out of the filter 300 driven by the pump assembly 22.

[0175] For example, the medical liquid pump tubing 1316 used to drive the flow of anticoagulant drugs driven by the pump assembly 22 is the pre-pump pump tubing 1315, and the medical liquid pump tubing 1316 used to drive the flow of medical liquid out of the filter 300 driven by the pump assembly 22 is the waste hydraulic pump tubing 1311.

[0176] Therefore, whether it is the medical liquid pump pipe section 1316 located in the first area 112 or the medical liquid pump pipe section 1316 located at the bottom of the second area 113, or the waste hydraulic pump pipe section 1311, in the event of damage to the waste hydraulic pump pipe section 1311, the leaked medical liquid waste liquid in the waste hydraulic pump pipe section 1311 is not likely to contaminate other medical pump pipe sections 131 located above the second area 113.

[0177] Furthermore, when the medical liquid pump tubing segment 1316 in the first region 112 is located above the blood pump tubing segment 1312 in the vertical direction, whether it is the medical liquid pump tubing segment 1316 in the first region 112 or the medical liquid pump tubing segment 1316 at the bottom of the second region 113, which is the pre-pump tubing segment 1315, since the pre-pump tubing segment 1315 and the blood pump tubing segment 1312 are adjacent, the blood drainage path 13404 or the blood pumping path 13405 connected to the blood pump tubing segment 1312 can be closer to the second inlet flow path 13409 connected to the pre-pump tubing segment 1315, thereby making the second inlet flow path 13409 shorter.

[0178] In some embodiments, the number of medical fluid pump segments 1316 may be at least four. For example, medical pump segments 131 include blood pump segment 1312, pre-pump blood pump segment 1315, dialysate pump segment 1313, and replacement fluid pump segment 1314.

[0179] Understandably, the pump body for pumping blood in the pump assembly 22 of the device housing 21 can be larger than the pump body for pumping medical fluids to ensure that the pump body for pumping blood can draw blood from the patient's blood vessels. Correspondingly, the radius of the blood pump tubing segment 1312 is also larger than the radius of the medical fluid pump tubing segment 1316. Therefore, by placing the blood pump tubing segment 131 and one medical fluid pump tubing segment 1316 in the first region 112, and placing at least three other medical fluid pump tubing segments 1316 in the second region 113, the space next to the first region 112 can be fully utilized to integrate at least three medical fluid pump tubing segments 1316, making the structure of the power panel 11 more compact, and correspondingly, the structure of the pump assembly 22 on the device housing 21 can also be more compact.

[0180] For example, the pump tubing 131 in the first region 112 consists of a pre-pump blood pump tubing 1315 and a blood pump tubing 1312 from top to bottom, and the pump tubing 131 in the second region 113 consists of a dialysate pump tubing 1313, a replacement fluid pump tubing 1314 and a waste hydraulic fluid pump tubing 1311 from top to bottom.

[0181] Alternatively, the pump tubing 131 in the first region 112 may be, from top to bottom, the pre-pump tubing 1315 and the blood pump tubing 1312, and the pump tubing 131 in the second region 113 may be, from top to bottom, the dialysate pump tubing 1313, the waste hydraulic fluid pump tubing 1311 and the replacement fluid pump tubing 1314.

[0182] Alternatively, the pump tubing 131 in the first region 112 may be, from top to bottom, the pre-pump tubing 1315 and the blood pump tubing 1312, and the pump tubing 131 in the second region 113 may be, from top to bottom, the replacement fluid pump tubing 1314, the dialysate pump tubing 1313 and the waste hydraulic fluid pump tubing 1311.

[0183] Alternatively, the pump tubing 131 in the first region 112 may be, from top to bottom, the pre-pump tubing 1315 and the blood pump tubing 1312, and the pump tubing 131 in the second region 113 may be, from top to bottom, the replacement fluid pump tubing 1314, the waste hydraulic fluid pump tubing 1311 and the dialysate pump tubing 1313.

[0184] Alternatively, the pump tubing 131 in the first region 112 may be, from top to bottom, a waste hydraulic pump tubing 1311 and a blood pump tubing 1312, and the pump tubing 131 in the second region 113 may be, from top to bottom, a dialysis fluid pump tubing 1313, a replacement fluid pump tubing 1314 and a blood pump pre-pump tubing 1315.

[0185] Alternatively, the pump tubing 131 in the first region 112 may be, from top to bottom, a waste hydraulic pump tubing 1311 and a blood pump tubing 1312, and the pump tubing 131 in the second region 113 may be, from top to bottom, a dialysis fluid pump tubing 1313, a blood pump pre-pump tubing 1315 and a replacement fluid pump tubing 1314.

[0186] Alternatively, the pump tubing 131 in the first region 112 may be, from top to bottom, a waste hydraulic pump tubing 1311 and a blood pump tubing 1312, and the pump tubing 131 in the second region 113 may be, from top to bottom, a replacement fluid pump tubing 1314, a dialysate pump tubing 1313 and a blood pump pre-pump tubing 1315.

[0187] Alternatively, the pump tubing 131 in the first region 112 may be, from top to bottom, a waste hydraulic pump tubing 1311 and a blood pump tubing 1312, and the pump tubing 131 in the second region 113 may be, from top to bottom, a replacement fluid pump tubing 1314, a blood pump pre-pump tubing 1315 and a dialysate pump tubing 1313.

[0188] In some embodiments, the first connection portion 111 of the power panel 11 may be located at least in the first region 112. For example, the medical liquid pump tubing segment 1316 and at least part of the first connection portion 111 in the first region 112 are arranged side by side in the horizontal direction and located above the blood pump tubing segment 1312, thereby making full use of the space above the blood pump tubing segment 1312.

[0189] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
