Description

Technical Field

[0001] This application relates to the field of medical technology, and more specifically, to a distributed dialysis machine network management system. Background Technology

[0002] Dialysis is a crucial form of renal replacement therapy for patients with kidney failure. However, traditional split-type dialysis machines present challenges such as cumbersome fluid management and high labor intensity during treatment. To address these issues, a Central Dialysis Fluid Delivery System (CDDS) has emerged, which prepares dialysis fluid and delivers it to multiple dialysis machines via pipelines, effectively reducing the labor intensity associated with fluid preparation and replacement.

[0003] However, currently, CDDS and dialysis machines mostly operate independently, with signal transmission between them primarily relying on conventional electrical signals and direct connections via PLC I / O signals. This leads to problems such as complex installation, high costs (numerous wiring harnesses), and very limited information transmission. Summary of the Invention

[0004] This application provides a distributed dialysis machine network management system, which can improve the shortcomings of existing technologies, such as having many wiring harnesses and transmitting little information.

[0005] This application is implemented as follows:

[0006] This application provides a distributed dialysis machine network management system, which includes a management platform, a centralized dialysis fluid supply device, and dialysis machines. The management platform is connected to the centralized dialysis fluid supply device via a distributed network. The management platform is used to centrally manage the centralized dialysis fluid supply device. The centralized dialysis fluid supply device is connected to multiple dialysis machines via a distributed network, so that the centralized dialysis fluid supply device supplies dialysis fluid to the dialysis machines respectively.

[0007] In one possible implementation, the dialysis machine is connected to the network of the centralized dialysis fluid supply equipment via a conversion box, which is used to convert the switch or analog control signals of the dialysis machine into network protocols that are compatible with the distributed network, thereby enabling distributed access to the network.

[0008] In one possible implementation, the management platform, the centralized dialysis fluid supply device, and the dialysis machine communicate via encoded information transmission direction, information type, and information address.

[0009] In one possible implementation, the information transmission direction includes the centralized dialysis fluid supply equipment to the dialysis machine, the dialysis machine to the centralized dialysis fluid supply equipment, the management platform to the dialysis machine, and the dialysis machine to the management platform.

[0010] In one possible implementation, when the centralized dialysis fluid supply device sets the variable information of the dialysis machine, it first sends the network address of the centralized dialysis fluid supply device, and then sends the information address and the value of the information address. After receiving the setting value, the dialysis machine replies with the node address, the information address and the response value, where the response value is success or failure.

[0011] In one possible implementation, when the centralized dialysis fluid supply device reads the variable information of the dialysis machine, it first sends the network address of the centralized dialysis fluid supply device, and then sends the value of the information address. After receiving the read variable address, the dialysis machine replies with the node address, the information address, the information value, and the response value, where the response value is success or failure.

[0012] In one possible implementation, the information type includes switch settings, 32-bit integers, 32-bit floating-point numbers, 64-bit floating-point numbers, and string values.

[0013] In one possible implementation, the information address includes dialysate temperature, dialysate pressure, dialysate flow rate, and dialysis start-up control.

[0014] In one possible implementation, the encoding consists of an 8-bit hexadecimal code.

[0015] In one possible implementation, the distributed network employs the RS-485-based Modbus protocol, the CAN bus-based CANOPEN protocol, the DeviceNet protocol, or the TCP-IP-based Modbus-TCP protocol.

[0016] This application has at least the following beneficial effects:

[0017] The distributed dialysis machine network management system of this application connects the management platform with the centralized dialysis fluid supply equipment and the centralized dialysis fluid supply equipment with multiple dialysis machines through a distributed network, thus having the advantages of fewer wiring harnesses and more information transmission.

[0022] Example

[0023] This embodiment provides a distributed dialysis machine network management system. Please refer to... Figure 1 It includes a management platform, a centralized dialysis fluid supply system (CDDS), and dialysis machines.

[0024] The management platform is connected to the centralized dialysis fluid supply equipment via a distributed network. The management platform is used for centralized management of the centralized dialysis fluid supply equipment. In other words, the management platform is a software management system running on a server that can centrally manage multiple CDDS devices, enabling functions such as centralized control, data acquisition, and statistical analysis.

[0025] The centralized dialysis fluid supply system is networked with multiple dialysis machines via a distributed network, enabling the centralized system to supply dialysis fluid to each machine. The CDDS (Cyclic Dialysis Distributor System) acts as a central node, providing one or more distributed access networks to connect the networked dialysis machines. Upstream, the CDDS acts as a managed node, receiving management from the management platform via a TCP / IP network.

[0026] In one implementation, the dialysis machine connects to the network of centralized dialysis fluid supply equipment via a conversion box. The conversion box converts the dialysis machine's digital or analog control signals into network protocols compatible with the distributed network, thus enabling distributed network access. It is understood that the end nodes of the distributed network are either dialysis machines or conversion boxes that support distributed networking. The dialysis machine can directly support network management internally; alternatively, it can connect via a conversion box, which converts the machine's digital or analog control signals into network protocols compatible with the distributed network, thereby enabling distributed access to the dialysis control network and achieving intelligent transformation.

[0027] The management platform, centralized dialysis fluid supply equipment, and dialysis machines communicate via coded information transmission direction, information type, and information address. Specifically, the code consists of an 8-bit hexadecimal code, with the information transmission direction, information type, and information address represented by 2 bits, 2 bits, and 4 bits, respectively. The CDDS and dialysis machines are networked through a distributed network. The CDDS, acting as the host computer, can provide multiple distributed networks. Within each distributed network, communication occurs with different slave devices (dialysis machines or converter boxes) using different address codes. Specific distributed networks employ Modbus protocol based on RS-485, CANOPEN protocol based on CAN bus, DeviceNet protocol, or Modbus-TCP protocol based on TCP-IP. Wired networks based on RS-485 and CAN bus offer advantages such as fewer signal lines and lower installation difficulty, while Modbus-TCP networks based on TCP-IP offer advantages such as good versatility and the ability to use wireless communication.

[0028] For example, the information transmission directions include centralized dialysis fluid supply equipment (host computer) to dialysis machine (slave computer), dialysis machine to centralized dialysis fluid supply equipment, management platform to dialysis machine, and dialysis machine to management platform. See the table below for details:

[0029] Table 1: Information Transmission Direction Encoding (2-bit hexadecimal number)

[0030] Serial Number Value significance 1 01 Settings (Host computer -> Slave computer) 2 81 Read (lower-level machine -> upper-level machine) 3 02 Transparent transmission (management platform -> slave device) 4 82 Transparent transmission (lower-level device -> management platform)

[0031] For example, the information types include switch settings, 32-bit integers, 32-bit floating-point numbers, 64-bit floating-point numbers, and string values. See the table below for details:

[0032] Table 2: Information Type Encoding (2-digit hexadecimal number)

[0033]

[0034]

[0035] For example, the information address includes dialysate temperature, dialysate pressure, dialysate flow rate, and dialysis start-up control. The information address code ranges from 0x0001 to 0xFFFE, representing specific control variables. Examples are shown in Table 3:

[0036] Table 3: Information Address Encoding (4-digit hexadecimal number)

[0037] Serial Number Information address value significance 1 0001 Dialysis fluid temperature 2 0002 Dialysis fluid pressure 3 0003 Dialysis fluid flow rate 4 0004 Dialysis operation start-up control

[0038] Among them, when the centralized dialysis fluid supply device (CDDS) communicates with the dialysis machine (lower-level machine), the communication is carried out in two ways depending on whether it is setting or reading.

[0039] When setting variable information for a dialysis machine using a centralized dialysis fluid supply device, the network address of the centralized dialysis fluid supply device is sent first, followed by the information address and its value. After receiving the setting value, the dialysis machine replies with the node address, information address, and response value, which indicates success or failure.

[0040] When the centralized dialysis fluid supply equipment reads the variable information of the dialysis machine, it first sends the network address of the centralized dialysis fluid supply equipment, and then sends the value of the information address. After receiving the variable reading address, the dialysis machine replies with the node address, information address, information value and response value. The response value is success or failure.

[0041] In summary, the distributed dialysis machine network management system of this application connects the management platform with the centralized dialysis fluid supply equipment and the centralized dialysis fluid supply equipment with multiple dialysis machines through a distributed network, thus having the advantages of fewer wiring harnesses and more information transmission.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
