Description

Technical Field

[0001] The present application relates to the field of medical technology, and in particular to a distributed dialysis machine networking management system. Background Art

[0002] Dialysis treatment, as an important form of renal replacement therapy, is crucial for patients with renal failure. However, traditional separate dialysis machines have problems such as cumbersome fluid change management and high labor intensity during treatment. For this reason, the Central Dialysis Fluid Delivery System (CDDS) has emerged, which configures the dialysis fluid and delivers it to multiple dialysis machines through pipelines, effectively reducing the labor intensity of the fluid preparation and fluid change processes.

[0003] However, the current CDDS and dialysis machines still operate independently in most cases, and the signal transmission between them is mostly carried out directly by conventional electrical signals, directly connected through the I / O signals of the PLC. This leads to problems such as complex construction, high cost (many wire harnesses), and very little information transmitted. Summary of the invention

[0004] The present application provides a distributed dialysis machine networking management system, which can improve the shortcomings of the prior art of having many wiring harnesses and little transmitted information.

[0005] This application is implemented as follows:

[0006] The present application provides a distributed dialysis machine networking management system, which includes a management platform, a centralized dialysis fluid supply device and a dialysis machine. The management platform and the centralized dialysis fluid supply device are networked via a distributed network. The management platform is used to perform networked centralized management of the centralized dialysis fluid supply device. The centralized dialysis fluid supply device is networked with a plurality of the dialysis machines via a distributed network so that the centralized dialysis fluid supply device supplies dialysis fluid to the dialysis machines respectively.

[0007] In a possible implementation, the dialysis machine is connected to the network of the centralized dialysis fluid supply device through a conversion box, and the conversion box is used to convert the switch quantity or analog control signal of the dialysis machine into a network protocol that complies with the network protocol supported by the distributed network, thereby enabling distributed access to the network.

[0008] In a possible implementation, the management platform, the centralized dialysate supply device and the dialysis machine communicate by encoding information transmission direction, information type and information address.

[0009] In a possible implementation, the information transmission direction includes from the centralized dialysate supply device to the dialysis machine, from the dialysis machine to the centralized dialysate supply device, from the management platform to the dialysis machine, and from the dialysis machine to the management platform.

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

[0011] In a possible implementation, when the centralized dialysate supply device reads the variable information of the dialysis machine, it first sends the network address of the centralized dialysate 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, information address, information value and response value, and the response value is success or failure.

[0012] In a possible implementation, the information types include switch quantity settings, 32-bit integer quantities, 32-bit floating point quantities, 64-bit floating point quantities, and character string quantities.

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

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

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

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

[0017] The distributed dialysis machine networking management system of the present application is connected to the management platform and the centralized dialysis fluid supply equipment, and the centralized dialysis fluid supply equipment and multiple dialysis machines through a distributed network, thereby having the advantages of fewer wires and more transmitted information.

[0021] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0022] Example

[0023] This embodiment provides a distributed dialysis machine networking management system. Figure 1 , which includes a management platform, a centralized dialysate supply system (CDDS) and a dialysis machine.

[0024] The management platform is connected to the centralized dialysate supply equipment through a distributed network, and the management platform is used to centrally manage the centralized dialysate supply equipment. That is, the management platform is a software management system running on the server, which can centrally manage multiple CDDSs online, and realize functions such as centralized control, data collection, and statistical analysis.

[0025] The centralized dialysate supply equipment is connected to multiple dialysis machines through a distributed network, so that the centralized dialysate supply equipment can supply dialysate to the dialysis machines respectively. CDDS, as a central node, provides one or more distributed access networks to access the networked dialysis machines. CDDS, as a managed node, is managed by the management platform through the TCP / IP network.

[0026] In one embodiment, the dialysis machine is connected to the network of the centralized dialysis fluid supply equipment through a conversion box, and the conversion box is used to convert the switch quantity or analog control signal of the dialysis machine into a network protocol that conforms to the distributed network support, thereby distributed access to the network. It is understandable that the dialysis machine or conversion box that supports distributed networking is located at the end node of the distributed network. Among them, the dialysis machine can directly support network management internally; or the dialysis machine can be connected through a conversion box, and the conversion box converts the switch quantity or analog control signal of the dialysis machine into a network protocol that conforms to the distributed network support, thereby distributed access to the dialysis control network to achieve intelligent transformation.

[0027] Among them, the management platform, the centralized dialysis fluid supply equipment and the dialysis machine communicate through the coded information transmission direction, information type and information address. Specifically, the coding is composed of 8-bit hexadecimal coding, and the information transmission direction, information type and information address are 2-bit coding, 2-bit coding and 4-bit coding respectively. CDDS and the dialysis machine are networked through a distributed network. As a host computer, CDDS can provide multiple distributed networks. In each distributed network, different address codes are used to communicate with different lower computers (dialysis machines or conversion boxes). The specific distributed network adopts Modbus protocol based on RS-485, CANOPEN protocol based on CAN bus, DeviceNet protocol, or Modbus-TCP protocol based on TCP-IP. Among them, the wired network based on RS-485 and CAN bus has the advantages of few signal lines and low construction difficulty, while the Modbus-TCP network using TCP-IP has good versatility and can adopt wireless communication.

[0028] Exemplarily, the information transmission direction includes centralized dialysate supply equipment (host computer) to dialysis machine (slave computer), dialysis machine to centralized dialysate supply equipment, management platform to dialysis machine, dialysis machine to management platform. The specific table is as follows:

[0029] Table 1: Information transmission direction coding (2-bit hexadecimal)

[0030] Serial number Value significance 1 01 Settings (upper computer -> lower computer) 2 81 Read (lower computer -> upper computer) 3 02 Transparent transmission (management platform -> lower computer) 4 82 Transparent transmission (lower computer -> management platform)

[0031] Exemplarily, the information type includes switch value setting, 32-bit integer value, 32-bit floating point value, 64-bit floating point value and string value. The details are as follows:

[0032] Table 2: Information type encoding (2-digit hexadecimal number)

[0033]

[0034]

[0035] Exemplarily, the information address includes dialysate temperature, dialysate pressure, dialysate flow rate and dialysis operation start control. The information address code value ranges from 0x0001 to 0xFFFE, indicating a specific control variable. For example, Table 3:

[0036] Table 3: Information address encoding (4-digit hexadecimal number)

[0037] Serial number Information address value significance 1 0001 Dialysate temperature 2 0002 Dialysate pressure 3 0003 Dialysate flow 4 0004 Dialysis run start control

[0038] Among them, when the centralized dialysate supply device (CDDS) communicates with the dialysis machine (slave computer), communication is divided into two situations depending on whether it is setting or reading.

[0039] When the centralized dialysate supply device sets the variable information of the dialysis machine, it first sends the network address of the centralized dialysate supply device, and then sends the information address and the value of the information address. After receiving the set value, the dialysis machine replies with the node address, information address and response value, and the response value is success or failure.

[0040] When the centralized dialysate supply device reads the variable information of the dialysis machine, it first sends the network address of the centralized dialysate 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, information address, information value and response value. The response value is success or failure.

[0041] In summary, in the distributed dialysis machine networking management system of the present application, the management platform and the centralized dialysis fluid supply equipment, as well as the centralized dialysis fluid supply equipment and multiple dialysis machines are all networked through a distributed network, thus having the advantages of fewer wiring harnesses and more information transmitted.

[0042] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
