Abstract

A blood purification device purifies blood of a patient, the blood purification device having: a storage section that stores patient information including inherent data and treatment data of the patient; an output section that outputs the patient information to the outside via an information acquisition device used by an operator of the blood purification device; a communication section that transmits the patient information to the outside using a communication line; and a control section that controls either of the output section and the communication section to perform migration of the patient information.

Description

Technical Field

[0001] This disclosure relates to blood purification devices, blood purification systems, and information migration methods for transferring patient information, and particularly to techniques for transferring patient information from a blood purification device to another blood purification device. Background Technology

[0002] Previously, as an example of treatment through blood purification, dialysis treatment using a blood purification device equipped with a dialyzer and a blood circuit is known. In this dialysis treatment, the following process is performed: blood drawn from the patient is circulated extracorporeally through the blood circuit, while the blood is purified using a dialyzer connected to the blood circuit, and the purified blood is returned to the patient. In medical facilities such as hospitals, multiple blood purification devices are installed in the dialysis room, enabling multiple patients to undergo dialysis treatment under different conditions.

[0003] During this dialysis treatment, individual treatment conditions are pre-set for each patient in the blood purification device. This pre-setting is performed by the operator of the blood purification device (a doctor or nurse, etc.) or by sending the treatment conditions from a server within the medical facility to each blood purification device. For example, Patent Document 1 discloses that in the event of a malfunction in the intended blood purification device, specific information about the patient and the other blood purification device is sent from another blood purification device to the server, and the treatment conditions calculated by the server are replied to the other blood purification device.

[0004] Furthermore, the treatment conditions and various information set in the blood purification device are sometimes stored on a server for various analyses. For example, Patent Document 2 discloses that an image acquisition device captures an image displayed on the monitor of the blood purification device and sends the image from the image acquisition device to a server. The server then decodes the treatment conditions and various information from the received image.

[0005] However, during dialysis treatment, dialysis may be interrupted due to malfunction of the blood purification device or other reasons, and treatment may be continued by another blood purification device, or the dialysis treatment may be discontinued. For treatment to continue by another blood purification device, it is important to be able to move the patient from the unusable device (the original device) to the newly selected device (the alternative device) and to quickly transfer various information, minimizing the lead time until treatment restart. This is because if treatment restart is time-consuming, the patient's blood will remain in the blood circuit, increasing the risk of blood clotting.

[0009] Patent Document 2: Japanese Patent Publication No. 2014-517709 Summary of the Invention

[0010] The technical problem that the invention aims to solve

[0011] However, the preferred methods for transferring various information vary depending on the status of the blood purification device or the environment in which it is set up, but these methods are insufficient to adequately address the issue and make it difficult to shorten the lead time until treatment is restarted.

[0012] For example, in the blood purification system disclosed in Patent Document 1, although treatment conditions can be sent from the server to the alternative device, the treatment process information cannot be retrieved from the original device, and various information cannot be fully transferred to the alternative device. Furthermore, in the blood purification system disclosed in Patent Document 1, because specific information about the patient and the alternative device is input at the alternative device side, human errors such as input mistakes sometimes occur, and this input can sometimes be time-consuming. Moreover, in the method for transmitting information disclosed in Patent Document 2, because it is limited to using images and image acquisition equipment related to various information, depending on the state of the blood purification device or the setting environment of the blood purification device, situations may sometimes arise where information cannot be transmitted, or time may be consumed.

[0013] This disclosure was made in view of the technical problem in which it aims to provide a blood purification device, blood purification system, and information migration method that can easily and accurately perform information migration and can shorten the lead time to treatment restart.

[0047] Hereinafter, with reference to the accompanying drawings, the blood purification apparatus and blood purification system having the present disclosure will be described in detail. It should be noted that the present disclosure is not limited to the following description and can be implemented by any modifications without changing its spirit. Furthermore, the drawings used in each embodiment schematically illustrate the blood purification apparatus and blood purification system having the present disclosure. For the purpose of better understanding, some parts have been emphasized, enlarged, reduced, or omitted, and sometimes the proportions and shapes of each component are not accurately represented. Moreover, the numerical values ​​used in each embodiment are shown as examples and can be modified in various ways as needed. Furthermore, common components in the drawings are labeled with the same reference numerals.

[0048] <First Implementation Method>

[0049] (Composition of a blood purification system)

[0050] First, refer to Figure 1The composition of a blood purification system having the blood purification apparatus of this disclosure will be described. Figure 1 This is a simplified diagram illustrating the configuration of the blood purification system 1 according to this embodiment. In particular, Figure 1 The diagram shows the communication relationships between the various components of the blood purification system 1.

[0051] like Figure 1 As shown, the blood purification system 1 according to this embodiment includes multiple blood purification devices 3 installed in a hospital 2, an in-hospital server (facility server) 4, and a portable terminal 5, wherein the hospital 2 is an example of a treatment facility. Furthermore, as... Figure 1 As shown, the blood purification system 1 also has a cloud server (off-site server) 7 that is communicatively connected to the blood purification device 3 within the hospital via network 6. It should be noted that the treatment facility is not limited to a hospital; it can be any facility capable of performing blood purification-related treatments. Furthermore, network 6 can be wireless, wired, or a combination thereof.

[0052] In Hospital 2, the blood purification device 3, the hospital server 4, and the portable terminal 5 are interconnected via the hospital network (wireless, wired, or a combination thereof) in a communicative manner. It should be noted that... Figure 1 In this configuration, the portable terminal 5 is connected only to the hospital server 4, but also to the blood purification device 3 in a communicable manner. Furthermore, the hospital server 4 and portable terminal 5, both located in hospital 2, can also communicate with the cloud server 7 via network 6. If the hospital server 4 functions as a communication server, the blood purification device 3 and portable terminal 5 can also communicate with the external cloud server 7 through the hospital server 4.

[0053] In the blood purification system 1, each blood purification device 3 is a device for performing treatments related to blood purification for the patient; its specific configuration will be described later. Each blood purification device 3 can send various data and information acquired within the device to an in-hospital server 4 or a cloud server 7. Here, data is generally envisioned as consisting of numerical values, symbols, or text obtained by processing signals, etc. Furthermore, information is generally envisioned as obtained through the collection or processing of this data; for example, it is envisioned as content intended for subsequent discussion by the recipient or that can be utilized by the recipient. However, regarding data and information, depending on its content and context, it may sometimes be used in situations that deviate from the above envisioning principles. It should be noted that... Figure 1 The text only describes two blood purification devices 3, but the number of blood purification devices 3 is not limited to this; the blood purification system 1 can also have three or more blood purification devices 3. Furthermore, the blood purification devices 3 are not limited to the same type of device; they can also be devices of different types and versions.

[0054] The hospital server 4 is a computer that manages and processes various data and information within hospital 2; its specific configuration will be described later. For example, the hospital server 4 can also process data or information received from the blood purification device 3 and send the processing results to the blood purification device 3 or the portable terminal 5. It should be noted that the hospital server 4 can be physically located inside hospital 2, or it can be located outside hospital 2 but function as a server for hospital 2. Furthermore, in Figure 1 In this context, the hospital server 4 is described as a single instance, but the various configurations and processing capabilities of the hospital server 4, as described later, can be distributed to multiple other server devices. In this case, when allocating the functions of the hospital server 4, a portion can be configured within the hospital 2, while the remainder can be configured outside the hospital.

[0055] Portable terminal 5 is a device that processes various received data and sends it to blood purification device 3 or in-hospital server 4; its specific configuration will be described later. For example, portable terminal 5 can be a wireless communication device, such as a smartphone, but it is not limited to this. For example, portable terminal 5 can also be a feature phone, portable information terminal, PDA, laptop computer, desktop computer, etc. It should be noted that... Figure 1 The text only describes one portable terminal 5, but the number of portable terminals 5 is not limited to this. The blood purification system 1 may also have two or more portable terminals 5.

[0056] Similar to the in-hospital server 4, the cloud server 7 is a computer that manages and processes various data and information within hospital 2; its specific structure will be described later. For example, the cloud server 7 can also process data or information received from the blood purification device 3 and send the processing results back to the blood purification device 3. It should be noted that... Figure 1 In this document, cloud server 7 is described as a single instance, but the various components and processing of cloud server 7, as described later, can also be distributed to multiple other server devices.

[0057] It should be noted that the blood purification system 1 only needs to be able to migrate patient information related to patients receiving blood purification treatment from one blood purification device 3 (the original device 3a described below) to other blood purification devices (the alternative device 3b described below), and it does not necessarily need to include all of the hospital server 4, portable terminal 5, and cloud server 7. That is, in environments where external communication is not possible, the blood purification system 1 may not have a cloud server 7 because it cannot connect to the cloud server 7. Furthermore, if the hospital 2's information management is possible solely through the cloud server 7 without setting up a hospital server 4, the blood purification system 1 may not have a hospital server 4. Consequently, the blood purification system 1 may also not have a portable terminal 5, and the patient information migration may be performed without using the portable terminal 5.

[0058] Furthermore, patient information includes both the patient's intrinsic data and treatment data. Intrinsic data includes data used to identify the patient and various other patient-related data. For example, intrinsic data may include treatment-related information such as the patient's name, gender, weight, height, and blood pressure. In addition, intrinsic data may include an ID used to identify the patient. On the other hand, treatment data may include data on treatment conditions, medical materials, accessories installed in the blood purification device (specification information), medications administered (anticoagulants), and the patient's treatment history. Specifically, treatment conditions may include treatment time, treatment mode (type), and prescription quantity. Accessories may include blood circuits, a blood purifier (dialyzer), syringes, saline solution, and dialysate. Treatment history data is data related to the patient's past and current treatments and may include internal parameters of the blood purification device 3, such as temperature, concentration, and pressure.

[0059] (Composition of a blood purification device)

[0060] Next, refer to Figures 2 to 5 The composition of the blood purification device disclosed herein will be described. Figure 2 This is a simplified diagram illustrating an example of the usage state of the blood purification device 3 according to this embodiment. Figure 3 This is a block diagram showing the electrical configuration of the blood purification device 3 according to this embodiment. Figure 4 This is a functional block diagram related to information migration of the blood purification device 3 involved in this embodiment, especially the original device 3a, which is the source of information migration. Figure 5 This is a functional block diagram related to information migration of the blood purification device 3 involved in this embodiment, especially a functional block diagram of the device that serves as the destination of information migration, namely the replacement device 3b.

[0061] like Figure 2As shown, the blood purification device 3 is composed of a dialysis apparatus for performing dialysis treatment on patient H. Specifically, the blood purification device 3 has a main body 12 mounted on a base unit 11, an input / output section 13 connected to the upper part of the main body 12, and a blood purifier 14 mounted on the side of the main body 12. Furthermore, the main body 12 of the blood purification device 3 includes an internal piping section 15 for circulating dialysate between itself and the blood purifier 14, an extracorporeal circulation section 16 for circulating blood, which is the body fluid of patient H, outside the body, and an information processing device 17. With this configuration, the blood purification device 3 can extract the blood of patient H outside the body, remove unwanted or toxic substances or water from the blood in the blood purifier 14, and return the purified blood to patient H.

[0062] The base unit 11 consists of a plate-shaped base 11a connected to the bottom of the main body 12 and four casters 11b disposed on the base 11a. This allows the blood purification device 3 to be moved easily. It should be noted that the number of casters 11b is not limited to four; three or more can be used as long as the blood purification device 3 can be moved.

[0063] The main body 12 is constructed of a generally rectangular shell. Furthermore, various constituent devices and components constituting the blood purification device 3 are arranged inside and on the surface of the main body 12. Here, as an example of a constituent device, there are pumps such as a duplex pump, a dewatering pump, a degassing pump, a pressurizing pump, a stock solution pump, and a blood pump, as well as various detectors.

[0064] The input / output unit 13 includes a display 13a and an input / output port 13b for connecting an external storage device (not shown). It should be noted that the display 13a and the input / output port 13b do not need to be side-by-side; the input / output port 13b can also be located on the front or back of the main body 12. Furthermore, the input port and output port 13b can be separate.

[0065] Next, as Figure 3 As shown, in the blood purification device 3, the display 13a, input / output port 13b, internal piping section 15, extracorporeal circulation section 16, information processing device 17, communication section 18, and reading section 19 are electrically connected to each other via control lines and data lines. Thus, in the blood purification device 3, the various electrical components can transmit and receive signals, data, and information, and various controls can be performed via the information processing device 17.

[0066] In this embodiment, a hemodialysis apparatus is described as an example of a blood purification apparatus 3, but it is not limited to this. For example, an acute blood purification apparatus, a peritoneal dialysis apparatus, an ultrafiltration apparatus, or a blood filtration apparatus can also be used as examples of blood purification apparatus 3. That is, in this disclosure, any apparatus can be used as long as patient information transfer processing can be performed from the blood purification apparatus 3.

[0067] 〔monitor〕

[0068] Next, the display 13a has a touch panel type input interface and a conventional screen type output interface. That is, the display 13a in this embodiment is a touch panel with input and output interfaces, and has input and output functions. Here, the input detection method of the touch panel can also be any method such as electrostatic capacitive or resistive film.

[0069] It should be noted that the input interface can also be separated from the display 13a. In this case, input devices such as a keyboard with physical keys such as numeric keys or text keys, and a mouse can also be installed in the blood purification device 3.

[0070] [Input / Output Ports]

[0071] The input / output port 13b consists of terminals for inputting and outputting information and data with various devices connected to the outside of the blood purification device 3. That is, the input / output port 13b can connect to various external storage devices (not shown) that serve as information acquisition devices, and has input / output functions that enable the blood purification device 3 to input and output information and data with these external storage devices. For example, the external storage device that can be connected to the input / output port 13b can be a USB (Universal Serial Bus) memory, a CF (CompactFlash) card, or an NFC (Near Field Communication) card, etc.

[0072] [Blood Purifier]

[0073] The blood purifier 14 has a blood inlet and a blood outlet at both ends of its housing, serving as blood-side ports, and a dialysate inlet and a dialysate outlet on the side of its housing, serving as dialysate-side ports. An arterial blood circuit L21 is connected to the blood inlet, and a venous blood circuit L22 is connected to the dialysate outlet.

[0074] The blood purifier 14 contains multiple hollow fiber membranes (not shown) that constitute a blood purification membrane for purifying blood. Within the blood purifier 14, separated by these membranes, are formed a blood flow path for the patient H's blood and a dialysate flow path for the dialysate. Furthermore, the hollow fiber membranes constituting the blood purification membranes have numerous tiny pores penetrating their outer and inner peripheral surfaces, allowing impurities in the blood to permeate through the membrane into the dialysate.

[0075] It should be noted that the blood purifier 14 is not limited to a dialyzer with the configuration described above. For example, it can also be an adsorption-type blood purifier used for endotoxin adsorption therapy, activated charcoal adsorption therapy, or bilirubin adsorption therapy. In addition, the blood purifier 14 can also be a hemodiafiltration filter.

[0076] [Internal piping department]

[0077] The internal piping section 15 is located inside the main body 12 and is connected to two terminals located on the side of the blood purifier 14 via piping L23. For example, the internal piping section 15 includes various components such as piping, pumps, valves, sensors, and filters. More specifically, the internal piping section 15 may also include a duplex pump, a dewatering pump, a degassing pump, a pressurizing pump, a pressure reducing valve, a solenoid valve, a temperature sensor, a pressure sensor, and a medication filter. Furthermore, the piping may be made of flexible materials such as polyvinyl chloride tubing or silicone tubing.

[0078] For the internal piping section 15, the aforementioned components are appropriately selected and assembled according to the piping configuration and type to form a structure capable of circulating and cleaning the dialysate. Furthermore, the internal piping section 15 is configured to allow the dialysate to be introduced into and out of the blood purification device 14. It should be noted that since these specific configurations are not characteristic of the blood purification device disclosed herein, their description is omitted.

[0079] [Extracorporeal Circulation Department]

[0080] The extracorporeal circulation unit 16 has a structure in which an arterial blood circuit L21 is connected to the blood inlet side of the blood purifier 14, and a venous blood circuit L22 is connected to the blood outlet side of the blood purifier 14. Furthermore, a fluid level adjustment circuit (not shown) is connected between the arterial blood circuit L21 and the venous blood circuit L22, bypassing the blood purifier 14. For example, the extracorporeal circulation unit 16 includes various components such as circuits, pumps, valves, sensors, and detectors. More specifically, the extracorporeal circulation unit 16 may also include connectors, solenoid valves, bubble detectors, blood pumps, blood concentration detectors, and air trap chambers. Furthermore, for example, each circuit may use flexible materials such as polyvinyl chloride tubing or silicone tubing.

[0081] With the blood purification device 3 running to purify the blood of patient H, the arterial side puncture needle and the venous side puncture needle (neither shown) are connected to the connector of the extracorporeal circulation unit, and each puncture needle is inserted into the arm of patient H. Then, in the arterial side blood circuit L21, the amount and concentration of blood taken from patient H are detected, and in the venous side blood circuit L22, the amount and concentration of blood returned to patient H are detected.

[0082] The solenoid valves, pumps, and detectors constituting the internal piping section 15 and the extracorporeal circulation section 16 are controlled to operate based on control signals supplied from the information processing device 17. Furthermore, these solenoid valves, pumps, and detectors can send status parameters to the information processing device 17 indicating the operational status of each component or part, or the blood purification device 3 having them. For example, these solenoid valves, pumps, and detectors can also send status parameters measured by various built-in sensors to the information processing device 17. That is, the status parameters can also be measured values ​​from various sensors. It should be noted that, in the absence of built-in sensors, status parameters can also be measured and sent by various sensors located near each component or part.

[0083] Similarly, each of the aforementioned pressure sensors can also send measured values ​​to the information processing device 17. Thus, the information processing device 17 can acquire various status parameters indicating the operational status of the extracorporeal circulation unit 16 of the blood purification device 3. On the other hand, since the aforementioned connectors, filters, and air collection chambers do not have sensing functions, their respective operating conditions can also be monitored by temperature or pressure sensors located nearby.

[0084] [Ministry of Communications]

[0085] Next, as Figure 3As shown, the communication unit 18 consists of a communication processing circuit 18a and an antenna 18b. The communication unit 18 transmits and receives information with the hospital server 4, portable terminal 5, and cloud server 7, which are separately located from the blood purification device 3, via the communication processing circuit 18a and the antenna 18b.

[0086] The communication processing circuit 18a can also perform processing based on a broadband wireless communication method, such as LTE. Furthermore, the communication processing circuit 18a can also perform processing based on a narrowband wireless communication method, such as IEEE 802.11 (e.g., wireless LAN) or Bluetooth (registered trademark). Moreover, the communication processing circuit 18a can also perform processing based on a contactless wireless communication method. In addition, the communication processing circuit 18a can replace such wireless communication, or utilize wired communication in addition to such wireless communication.

[0087] [Reading Department]

[0088] The reading unit 19 is an example of an information acquisition device, and is a general reader device for one-dimensional or two-dimensional identification marks. In this embodiment, the reading unit 19 reads the identification marks displayed on the display 13a of another blood purification device 3 (i.e., the original device 3a) or the display of the portable terminal 5. For example, the reading unit 19 optically detects the identification marks and analyzes the pattern of black and white (blank) portions, thereby converting them into specific information (patient information).

[0089] Specifically, the reading unit 19 has a light source and a light sensor, and may also have a structure for scanning and identifying marks. In this case, the output of the light sensor is amplified and digitized from a weak analog signal. In particular, blank areas have high reflectivity, so they are converted into a digital signal of "0", while black areas have low reflectivity, so they are converted into a digital signal of "1". Then, the pattern is decoded by the information processing device 17, and information can be output through various interfaces.

[0090] It should be noted that the reading unit 19 can also be connected to the main body 12 via a retractable cable. This allows the reading unit 19 to be separated from the main body 12, enabling it to be placed close to the identification mark being read. Furthermore, if the blood purification device 3 does not require reading the identification mark, the reading unit 19 may not be necessary.

[0091] [Information processing device]

[0092] like Figure 3 As shown, the information processing device 17 involved in this embodiment is composed of a processor 17a and a memory 17b.

[0093] The processor 17a, composed of a GPU (Graphics Processing Unit) or a CPU (Central Processing Unit), functions as a control unit that controls other connected components or devices based on various programs stored in the memory 17b. Specifically, the processor 17a reads and executes programs for performing blood purification processing or programs for executing the operating system from the memory 17b. Furthermore, the processor 17a performs processing related to information migration and initial settings within the blood purification device 3. It should be noted that the processor 17a can be composed of a single GPU or CPU, or it can be composed of multiple GPUs or CPUs combined.

[0094] The memory 17b, composed of ROM, RAM, non-volatile memory, HDD, etc., functions as a storage unit. The ROM stores instruction commands for performing blood purification processing as programs. Furthermore, the ROM stores instruction commands for performing processes related to information migration and initial settings in the blood purification device 3 as programs. The RAM is used to write and read data during the processing of the program stored in the ROM by the processor 17a. Moreover, the non-volatile memory is a storage device for writing and reading data during the execution of the program; data written here is retained even after the program execution ends.

[0095] As described above, in this embodiment, a processing program related to the initial settings of the information migration process in the blood purification device 3 and migration method data representing its content are stored. In particular, the memory 17b stores programs related to four migration methods and migration method data representing their content. Specifically, as a first migration method, the following method is stored: generating an identification mark related to patient information and displaying it on the display 13a, and performing information migration by reading it through a reading device such as a portable terminal 5. Furthermore, as a second migration method, a method is stored to perform information migration by storing patient information in an external storage device via the input / output port 13b. Furthermore, as a third migration method, a method is stored to perform information migration by sending patient information to the hospital server 4 via the communication unit 18. Moreover, as a fourth migration method, a method is stored to perform information migration by sending patient information to the cloud server 7 via the communication unit 18. Here, the first and second migration methods require the participation of the operator of the blood purification device 3 (operator-intervention type migration methods), while the third and fourth migration methods are methods that can be executed automatically without the participation of the operator (communication type migration methods). It should be noted that the processing performed through this program will be described later.

[0096] In the first migration method, patient information is converted into an identification tag, and the information migration is performed by reading this identification tag, thus ensuring information security. Furthermore, in the second migration method, information migration is performed by plugging and unplugging an external storage device, making information migration easier compared to the first method. On the other hand, in the third and fourth migration methods, information migration is performed automatically using communication lines, thus eliminating the need for operator intervention and reducing the burden associated with information migration.

[0097] Furthermore, the memory 17b stores at least one of the first to fourth migration methods initially selected by the operator as initial selection information. That is, the memory 17b stores methods that are selected as candidates for the migration method when patient information migration is required. It should be noted that the process related to this initial selection and the storage of the initial selection information will be described later.

[0098] Furthermore, the memory 17b stores up-to-date patient information related to the patient's treatment. Additionally, the memory 17b also stores migration procedure information related to patient information migration and differential information between the old and new patient information. The contents of this information will be described later.

[0099] (Functional composition of information processing device)

[0100] Next, refer to Figure 4 and Figure 5 The functional configuration of the blood purification device 3 according to this embodiment will be described here. Figure 4 and Figure 5 This is a functional block diagram related to information migration in the blood purification device 3 according to the first embodiment. In particular, Figure 4 The functional configuration of the blood purification device 3 as the information migration source (i.e., the original device 3a) is shown. Figure 5 The functional configuration of the blood purification device 3 as the destination of information migration (i.e., the case of replacing device 3b) is shown. Furthermore, in Figure 4 and Figure 5 It also records the flow of information and data between the various components.

[0101] like Figure 4 and Figure 5 As shown, the information processing device 17 includes a control unit 21 and a storage unit 22. Furthermore, the control unit 21 includes a selection image generation unit 21a, a recognition tag generation unit 21b, and an arithmetic unit 21c. These components function through the processor 17a and memory 17b of the information processing device 17 themselves, or by the processor 17a reading and executing a program stored in the memory 17b.

[0102] like Figure 4 As shown, when the blood purification device 3 is the original device 3a serving as the information transfer source, the image generation unit 21a receives data from the storage unit 22 using four transfer methods to obtain patient information stored in the storage unit 22. Figure 4 In the A section (migration method data), an initial selection image is generated for the operator to select a migration method in the initial stage. Furthermore, the selection image generation unit 21a sends the generated initial selection image to the display 13a (…). Figure 4 B in the image selection unit 21a receives initial selection information input from the display 13a by the operator of the blood purification device 3 through operation of the display 13a. Figure 4 C in the image generation unit 21a then sends the received initial selection information to the storage unit 22. Figure 4 The initial selection information (D in the text) is stored in the storage unit 22.

[0103] When the original device 3a, which is the blood purification device 3, causes the treatment to be interrupted due to malfunction or other reasons, the image generation unit 21a receives the initial selection information stored in the storage unit 22 from the storage unit 22. Figure 4 The selection image generation unit 21a generates the final selection image (D: initial selection information) and generates a final selection image for the operator to select a migration method during the actual information migration phase. Furthermore, the selection image generation unit 21a sends the generated final selection image to the display 13a. Figure 4 E in the image selection unit 21a then receives operator selection information input by the operator of the blood purification device 3 through operation of the display 13a from the display 13a. Figure 4 F in the text: Operator selection information.

[0104] When the final method for information migration is selected, the control unit 21 receives the patient information stored in the storage unit 22 from the storage unit 22. Figure 4 In the text, G represents patient information. Furthermore, the control unit 21 performs patient information migration processing based on the selected information migration method. That is, the control unit 21 controls either the input / output unit 13 or the communication unit 18 to perform the patient information migration processing. Specifically, when the first migration method using an identification tag is selected, the identification tag generation unit 21b generates an identification tag corresponding to the patient information and sends the identification tag to the display (…). Figure 4 H1 in the diagram: Identification mark), causing the display 13a to show the identification mark. If the second migration method utilizing an external storage device is selected, the control unit 21 sends the received patient information to the input / output port 13b (…). Figure 4H2: Patient Information), so that the external storage device connected to input / output port 13b stores the patient information. If the third or fourth migration method using the hospital server 4 or cloud server 7 is selected, the control unit 21 sends the received patient information to the destination server via the communication unit 18. Figure 4 H3 in the document: Patient Information.

[0105] like Figure 5 As shown, when the blood purification device 3 is a replacement device 3b serving as the destination for information migration, the data or information required for information migration is input. Specifically, when the first migration method using an identification tag is selected in the original device 3a, the control unit 21 receives the identification tag read by the reading unit 19. Figure 5 J1 in the original device 3a: identification mark). When the second migration method using an external storage device is selected in the original device 3a, the control unit 21 reads the patient information from the external storage device connected to the input / output port 13b and receives the patient information via the input / output port 13b. Figure 5 J2: Patient information). When the third or fourth migration method using the hospital server 4 or cloud server 7 is selected in the original device 3a, the control unit 21 receives patient information, migration procedure method, and differential information from the sending source server via the communication unit 18. Figure 5 J3 in the text: Patient information, migration procedure methods, differential information.

[0106] The control unit 21 sends the received information to the storage unit 22, where patient information, etc., is stored. Specifically, when the first migration method using identification tags is selected, the calculation unit 21c performs image processing on the received identification tags to obtain patient information. Furthermore, the calculation unit 21c reads historical patient information stored in the storage unit 22 and compares it with newly obtained patient information from the identification tags to generate differential information. Then, the calculation unit 21c generates migration procedure information based on the patient information and the differential information. Finally, the calculation unit 21c sends the acquired patient information, the generated differential information, and the migration procedure information to the storage unit 22. Figure 5 K in the text refers to patient information, migration procedure information, and differential information. This information is stored in the storage unit 22.

[0107] When the second migration method utilizing an external storage device is selected in the original device 3a, the arithmetic unit 21c reads the historical patient information stored in the storage unit 22 and compares it with the patient information received via the input / output port 13b to generate differential information. Furthermore, the arithmetic unit 21c generates migration procedure information based on the patient information and the differential information. Then, the arithmetic unit 21c sends the acquired patient information, the generated differential information, and the migration procedure information to the storage unit 22. Figure 5 K in the text refers to patient information, migration procedure information, and differential information. This information is stored in the storage unit 22.

[0108] When the third or fourth migration method using the hospital server 4 or cloud server 7 is selected in the original device 3a, the control unit 21 sends the received patient information, differential information, and migration procedure information to the storage unit 22. Figure 5 K in the text refers to patient information, migration procedure information, and differential information. This information is stored in the storage unit 22.

[0109] In addition, the control unit 21 sends the received or generated patient information, migration procedure information, and differential information to the display 13a ( Figure 5 The L in the image represents patient information, migration procedure information, and differential information, which are displayed on the monitor 13a. Thus, the operator can confirm patient information, migration procedure information, and differential information via the monitor 13a, enabling accurate and rapid information migration.

[0110] (Internal server)

[0111] Next, refer to Figure 6 The electrical configuration of the hospital server 4, which constitutes the blood purification system of this disclosure, will be described here. Figure 6 This is a block diagram illustrating the electrical configuration of the in-hospital server 4 according to the first embodiment. It should be noted that the in-hospital server 4 does not necessarily need to possess… Figure 6 All the constituent elements shown can be arranged either by omitting some or by adding other constituent elements.

[0112] like Figure 6 As shown, the in-house server 4 has an input / output unit 43 consisting of a display 43a and input / output ports 43b, an information processing device 47 consisting of a processor 47a and a memory 47b, and a communication unit 48 consisting of a communication processing circuit 48a and an antenna 48b. Moreover, these components are electrically connected to each other via control lines and data lines.

[0113] The display 43a has a typical screen-type output interface. That is, the display 43a in this embodiment differs from the display 13a of the blood purification device 3, and only has an output function. It should be noted that the display 43a may also be a touch panel with input / output interfaces, just like the display 13a of the blood purification device 3.

[0114] Similar to the input / output port 13b of the blood purification device 3, the input / output port 43b consists of terminals for inputting and outputting information and data with various devices connected to the hospital server 4. That is, the input / output port 43b can connect to an external storage device (not shown) and has input / output functions that enable the hospital server 4 to input and output information and data with this external storage device. For example, the external storage device that can be connected to the input / output port 43b can be a USB memory, CF card, or NFC card, etc. It should be noted that the hospital server 4 may not have an input / output port 43b if no external storage device is connected.

[0115] The processor 47a, comprised of a GPU or CPU, functions as a control unit for controlling other directly connected devices and other devices connected via communication lines based on various programs stored in the memory 47b. For example, the processor 47a reads programs from the memory 47b for performing information processing related to this disclosure and programs for performing OS functions, and executes them. More specifically, in order to perform patient information migration-related processing, the processor 47a performs processing, transmission, and other processing of the received patient information. In particular, similar to the control unit 21 of the blood purification device 3, the processor 47a generates migration procedure information and differential information based on the latest received patient information and the historical patient information stored in the memory 47b. Details of these processes will be described later. It should be noted that the processor 47a can be comprised of a single CPU, or multiple CPUs.

[0116] The memory 47b includes RAM, ROM, non-volatile memory, and HDD, and functions as a storage unit. The ROM stores instructions for executing the information processing and OS functions disclosed herein as programs. Such programs are loaded and executed by the processor 47a. The RAM is used to write and read data during the processing of the programs stored in the ROM by the processor 47a. The non-volatile memory is a memory where data is written and read during the execution of the program; data written here is retained even after the program execution ends. In particular, in this disclosure, the memory 47b stores programs for performing processing, transmission, and other processes related to receiving patient information to perform patient information migration-related processing.

[0117] In addition, the memory 47b stores patient information related to the treatment of multiple patients. Similar to the storage unit 22 of the blood purification device 3, the memory 47b also stores migration procedure information, which is a procedure related to the migration of patient information, and differential information between old and new patient information.

[0118] The communication unit 48 communicates with the blood purification device 3 or portable terminal 5 located within the hospital, or the remotely located cloud server 7, via the communication processing circuit 48a and the antenna 48b. The communication processing circuit 48a processes the programs and various information used in the blood purification system 1 for communication with the blood purification device 3, portable terminal 5, or cloud server 7, according to the progress of the processing.

[0119] It should be noted that the communication processing circuit 48a is based on broadband wireless communication methods such as LTE, but it can also be based on wireless LAN such as IEEE 802.11, narrowband wireless communication such as Bluetooth (registered trademark), and contactless wireless communication. Furthermore, it can replace wireless communication, or use wired communication in addition to wireless communication.

[0120] (Portable terminal)

[0121] Next, refer to Figure 7 The electrical configuration of the portable terminal 5 constituting the blood purification system of this disclosure will be described here. Figure 7 This is a block diagram illustrating the electrical configuration of the portable terminal 5 according to the first embodiment. It should be noted that the portable terminal 5 does not necessarily need to possess... Figure 7 All the constituent elements shown can be arranged either by omitting some or by adding other constituent elements.

[0122] like Figure 7 As shown, the portable terminal 5 includes a display 53a, an information processing device 57 consisting of a processor 57a and a memory 57b, a communication unit 58 consisting of a communication processing circuit 58a and an antenna 58b, and a reading unit 59. Moreover, these components are electrically connected to each other via control lines and data lines.

[0123] Next, the display 53a has a touch panel type input interface and a conventional screen type output interface. That is, the display 53a in this embodiment is a touch panel with input and output interfaces, possessing both input and output functions. Here, the input detection method of the touch panel can be any method, such as capacitive or resistive film. In particular, in this embodiment, the display 13a displays patient information obtained from the blood purification device 3, or displays identification marks read from the blood purification device 3.

[0124] The processor 57a, comprised of a GPU or CPU, functions as a control unit for controlling the various components of the portable terminal 5 based on various programs stored in the memory 57b. For example, the processor 57a reads and executes programs from the memory 57b for performing information processing related to this disclosure and programs for performing OS functions. More specifically, in order to perform patient information migration-related processing, the processor 57a performs information processing such as reading an identification tag via the reading unit 59, obtaining patient information from the read identification tag, and displaying the patient information on the display 53a, as well as displaying the identification tag on the display 53a. Details of these processes will be described later. It should be noted that the processor 57a may be comprised of a single GPU or CPU, or multiple GPUs or CPUs.

[0125] The memory 57b includes RAM, ROM, non-volatile memory, and HDD, and functions as a storage unit. The ROM stores instructions for executing the information processing and OS functions disclosed herein as programs. Such programs are loaded and executed by the processor 57a. The RAM is used to write and read data during the processing of the program stored in the ROM by the processor 57a. The non-volatile memory is a memory where data is written and read during the execution of the program; data written there is retained even after the program execution ends. In particular, in this disclosure, the memory 57b stores programs for performing patient information migration-related processing, such as reading an identification tag via the reading unit 59, obtaining patient information from the read identification tag, displaying the patient information on the display 53a, and displaying the identification tag on the display 53a.

[0126] The communication unit 58 communicates with the blood purification device 3 located within the hospital, the hospital server 4, or the remotely located cloud server 7 via the communication processing circuit 58a and the antenna 58b. The communication processing circuit 58a processes the programs and various information used in the blood purification system 1 for communication with the blood purification device 3, the hospital server 4, or the cloud server 7, according to the progress of the processing.

[0127] It should be noted that the communication processing circuit 58a is based on broadband wireless communication methods such as LTE, but it can also be based on wireless LAN such as IEEE 802.11, narrowband wireless communication such as Bluetooth (registered trademark), and contactless wireless communication. Furthermore, it can replace wireless communication, or use wired communication in addition to wireless communication.

[0128] The reading unit 59 is a general camera, an information acquisition device capable of reading one-dimensional or two-dimensional identification marks. In this embodiment, the reading unit 59 reads the identification marks displayed on the display 13a of the blood purification device 3 (original device 3a). For example, similar to the reading unit 19 of the blood purification device 3, the reading unit 59 optically detects the identification marks and analyzes the pattern of black and white (blank) portions, thereby converting them into specific information (patient information).

[0129] It should be noted that in this embodiment, the display 53a and the reading unit 59 of the portable terminal 5 are used to read and display the identification mark, but it is not limited to this. That is, a dedicated reading terminal for reading and displaying the identification mark may be prepared separately from the portable terminal 5 and used as a component of the blood purification system 1.

[0130] (Cloud server)

[0131] Next, refer to Figure 8 The electrical configuration of the cloud server 7 constituting the blood purification system of this disclosure will be described here. Figure 8 This is a block diagram illustrating the electrical configuration of the cloud server 7 according to the first embodiment. It should be noted that the cloud server 7 does not necessarily need to possess... Figure 8 All the constituent elements shown can be arranged either by omitting some or by adding other constituent elements.

[0132] like Figure 8 As shown, the cloud server 7 has an information processing device 77 consisting of a processor 77a and a memory 77b, and a communication unit 78 consisting of a communication processing circuit 78a and an antenna 78b. Moreover, these components are electrically connected to each other via control lines and data lines.

[0133] The processor 77a, composed of a GPU or CPU, functions as a control unit for controlling other directly connected devices and other devices connected via communication lines based on various programs stored in the memory 77b. For example, the processor 77a reads programs from the memory 77b for performing the information processing involved in this disclosure and programs for performing OS functions, and executes them. More specifically, in order to perform patient information migration-related processing, the processor 77a performs processing, transmission, and other processing of the received patient information. In particular, similar to the control unit 21 of the blood purification device 3, the processor 77a generates migration procedure information and differential information based on the latest received patient information and the historical patient information stored in the memory 77b. Details of these processes will be described later. It should be noted that the processor 77a can be composed of a single GPU or CPU, or multiple GPUs or CPUs.

[0134] The memory 77b includes RAM, ROM, non-volatile memory, and HDD, and functions as a storage unit. The ROM stores instructions for executing the information processing and OS functions disclosed herein as programs. Such programs are loaded and executed by the processor 77a. The RAM is used to write and read data during the processing of the programs stored in the ROM by the processor 77a. The non-volatile memory is a memory where data is written and read during the execution of the program; data written there is retained even after the program execution ends. In particular, in this disclosure, the memory 77b stores programs for performing processing, transmission, and other processes related to receiving patient information to perform patient information migration-related processing.

[0135] In addition, the memory 77b stores patient information related to the treatment of multiple patients. Similar to the storage unit 22 of the blood purification device 3, the memory 77b also stores migration procedure information, which is a procedure related to the migration of patient information, and differential information between old and new patient information.

[0136] The communication unit 78 transmits and receives information with the remotely installed blood purification device 3, hospital server 4, or portable terminal 5 via the communication processing circuit 78a and antenna 78b. The communication processing circuit 78a processes the programs and various information used in the blood purification system 1 for transmitting and receiving information with the blood purification device 3, hospital server 4, or portable terminal 5 according to the progress of the processing.

[0137] It should be noted that the communication processing circuit 78a is based on broadband wireless communication methods such as LTE, but it can also be based on wireless LAN such as IEEE 802.11, narrowband wireless communication such as Bluetooth, and contactless wireless communication. Furthermore, it can replace wireless communication, or use wired communication in addition to wireless communication.

[0138] (Processing in a blood purification system)

[0139] Next, regarding the processing related to the migration of patient information in the blood purification system 1 according to this embodiment, please refer to... Figures 9A to 12 The first to fourth migration methods will be explained separately. Here, Figure 9A , Figures 10 to 12 This is a timing diagram related to information migration in the blood purification system 1 of this embodiment. Figures 9B to 9H This is an example of a screen displayed in the blood purification device 3 according to this embodiment. In particular, Figure 9A This is the timing diagram when the first migration method is selected. Figure 10This is the timing diagram when the second transfer method is selected. Figure 11 This is the timing diagram when the third transfer method is selected. Figure 12 This is the timing diagram when the fourth transfer method is selected.

[0140] [First migration method]

[0141] First, regarding the first migration method, such as Figure 9A As shown, initial settings (S1 and S2) related to information migration are performed in each blood purification device 3 (original device 3a and replacement device 3b). These initial settings are performed by the operator of each blood purification device 3 at the time the device is introduced into the hospital. Specifically, the information processing unit 17 of the blood purification device 3 displays initial selection information on the display 13a, placing it in a state selectable by the operator. For example, as... Figure 9B As shown, the display 13a displays: a title display 81 with the operation title "Initial Selection of Information Migration Method"; a first selection button 82 displaying "Migration using identification marks" as the first migration method; a second selection button 83 displaying "Migration using external storage device" as the second migration method; a third selection button 84 displaying "Migration using internal server" as the third migration method; a fourth selection button 85 displaying "Migration using cloud server" as the fourth migration method; and a save button 86 displaying "Select Save" for selecting and saving the migration method.

[0142] Here, in Figure 9B In the process, the operator presses the first selection button 82 and the third selection button 84 to select the first migration method and the third migration method, respectively, and the buttons are displayed in darker colors. Then, by pressing the save button 86, the first migration method and the third migration method are sent to the control unit 21 as initial selection information. Afterwards, the control unit 21 sends the initial selection information to the storage unit 22 (memory 17b), where the initial selection information is stored.

[0143] Next, treatment begins in the blood purification device 3 (original device 3a) (S3). Specifically, the operator connects the accessories to the blood purification device 3, prepares the medication, performs a puncture on the patient, sets the treatment conditions corresponding to the patient, and begins the treatment for each patient. It should be noted that data related to the newly implemented treatment, as patient information, is appropriately stored in the storage unit 22 through processing by the control unit 21.

[0144] Subsequently, a blood purification device 3 malfunctions for some reason, resulting in a treatment interruption in the original device 3a (S4). When the control unit 21 of the original device 3a detects the treatment interruption, it performs a selection process for the migration method in the original device 3a (S5). Specifically, the control unit 21 reads the initial selection information from the storage unit 22, and the selection image generation unit 21a generates a final selection image, which is then sent to the display 13a for display.

[0145] For example, such as Figure 9C As shown, the display 13a displays: a title display 91 with the operation title "Final Selection of Information Migration Method"; a first selection button 92 displaying "Migration using identification marks" as the first migration method; a second selection button 93 displaying "Migration using external storage device" as the second migration method; a third selection button 94 displaying "Migration using internal server" as the third migration method; a fourth selection button 95 displaying "Migration using cloud server" as the fourth migration method; and a confirmation button 96 displaying "Select Confirm" for selecting and confirming the migration method.

[0146] In this embodiment, since the second and fourth migration methods were not selected during the initial selection phase, the second selection button 93 and the fourth selection button 95 are displayed in a blacked-out state, indicating that they cannot be selected by the operator. It should be noted that the second selection button 93 and the fourth selection button 95, which are related to the second and fourth migration methods not selected during the initial selection phase, may also not be displayed on the display 13a, making them invisible and unselectable by the operator. On the other hand, to expand the options in this phase, the second selection button 93 and the fourth selection button 95 may also be displayed in a selectable manner.

[0147] Then, in Figure 9C In the process, the operator presses the first selection button 92 to select the first migration method; the first selection button 92 is displayed in a darker color. Afterwards, the operator presses the confirm button 96, indicating that the first migration method has been selected; this final selection information is then sent to the control unit 21.

[0148] Next, in the original device 3a, the identification mark is displayed on the display 13a (S6). Specifically, the identification mark generation unit 21b of the control unit 21 reads patient information from the storage unit 22 upon receiving operator selection information. This patient information includes the patient's inherent data and treatment data received in the original device 3a, and the treatment data also includes treatment process data related to the start and end of treatment. That is, the patient information includes the information required to transfer treatment from the original device 3a to the replacement device 3b. Then, the identification mark generation unit 21b generates a one-dimensional or two-dimensional identification mark corresponding to the patient information and sends the identification mark to the display 13a for display. For example, as Figure 9D As shown, a two-dimensional QR code (registered trademark) can also be displayed as an identification mark on the mark display section 97 of the display 13a.

[0149] Next, the portable terminal 5 is used to photograph the identification mark displayed on the display 13a of the original device 3a (S7). Specifically, in the portable terminal 5 held by the operator of the blood purification device 3, the operator operates the screen displayed on the display 53a, and the information processing device 57 of the portable terminal 5 executes the identification mark photographing procedure. Then, the reading unit 59 of the portable terminal 5 is controlled to operate, and the identification mark displayed on the display 13a of the original device 3a is photographed.

[0150] Next, the information processing device 57 of the portable terminal 5 performs image processing on the captured identification marker to obtain patient information, and displays the patient information on the display 53a (S8). For example, as Figure 9E As shown, alternatively, on display 53a, the patient's inherent data, which is one type of patient information, is displayed on display unit 98, while treatment data, which is another type of patient information, is displayed on display unit 99. Alternatively, display unit 98 may display the patient's name, gender, weight, height, and blood pressure, while display unit 99 may display data on treatment conditions, medical materials, accessories installed in the blood purification device, medication administered, and the patient's treatment progress. This allows the operator of the blood purification device 3 to easily and quickly confirm information about patients whose treatment has been interrupted and their treatment status.

[0151] Next, the same identification mark as the identification mark displayed on the display 13a of the original device 3a is displayed on the display 53a of the portable terminal 5 (S9). Specifically, in the portable terminal 5 held by the operator, the operator operates the screen displayed on the display 53a, and the information processing device 57 of the portable terminal 5 executes the procedure to display the identification mark again.

[0152] Next, by operating the alternative device 3b, which serves as the destination for information migration, the identification mark displayed on the display 53a is photographed (S10). Specifically, the operator of the blood purification device 3 operates the screen displayed on the display 13a of the alternative device 3b, and the information processing unit 17 of the alternative device 3b executes the identification mark photographing procedure. Then, the reading unit 19 of the alternative device 3b is controlled to operate, and the identification mark displayed on the display 53a of the portable terminal 5 is photographed.

[0153] Next, the information processing unit 17 of the replacement device 3b performs image processing on the captured identification mark to acquire patient information, and performs information processing related to the patient information (S11). Specifically, the arithmetic unit 21c, which functions through the information processing unit 17 of the replacement device 3b, performs image processing on the identification mark received from the reading unit 19 to acquire patient information, and performs the installation of the patient information. As a result, the replacement device 3b can take over the patient information of the original device 3a and can perform rapid migration processing using the patient information of the original device 3a. In addition, the arithmetic unit 21c reads the historical patient information stored in the storage unit 22, compares it with the newly acquired patient information from the identification mark, extracts the difference, and generates difference information related to the patient information. Furthermore, the arithmetic unit 21c also generates migration procedure information representing the migration procedure of the patient information in the replacement device 3b based on the newly acquired patient information and the generated difference information.

[0154] Next, in the alternative device 3b, the migration procedure information generated through patient information processing is displayed on the display 13a (S12). Specifically, the control unit 21 of the alternative device 3b sends the migration procedure information to the display 13a and displays the migration procedure information on the display 13a so that the operator can confirm it. For example, as Figure 9F As shown, the display 13a shows: a title display 101 displaying the operation title "Migration Procedure Guide"; a migration procedure display 102 displaying the "First Step" of the processing content as the initial stage of the migration procedure; and a jump button 103 displaying "Next Step" for proceeding to the next step. Then, when the operator presses the jump button 103, the migration procedure proceeds sequentially. Figure 9G As shown, when the final step is displayed on the migration procedure display unit 102, a completion button 104 with the word "Completed" is displayed below the display 13a to enable the control unit 21 to recognize that the migration procedure operation has been completed.

[0155] It should be noted that the display related to the migration procedure guide is not limited to the above content. All steps can be displayed simultaneously, or the user can scroll to the next step. Additionally, other jump buttons with a "back" option can be displayed to allow users to return to the previous step and reconfirm its content.

[0156] Next, in the replacement device 3b, the differential information generated through patient information processing is displayed on the display 13a (S13). Specifically, the control unit 21 of the replacement device 3b sends the differential information to the display 13a and displays the differential information on the display 13a so that the operator can confirm it. For example, such as Figure 9H As shown, the display 13a displays: a title display 111 displaying the title "Differential Information"; a differential display 112 displaying differential information related to the device; a differential display 113 displaying differential information related to treatment conditions; a differential display 114 displaying differential information related to treatment data; and a confirmation button 115 displaying "Confirm" to allow the control unit 21 to recognize that differential confirmation is complete. Each differential display shows information stored in the original device 3a as information before migration, and information stored in the replacement device 3b as information after migration. This allows the operator to easily grasp the points to be noted during migration processing and enables rapid migration processing.

[0157] It should be noted that the display order of the migration procedure information in S12 and the differential information in S13 can be reversed. Alternatively, the information can be displayed in a way that allows both pieces of information to be confirmed simultaneously.

[0158] Next, in the alternative device 3b, the operator performs various migration procedures (S14). Specifically, this includes setting treatment conditions, installing accessories, preparing medications, and moving the patient. It should be noted that the operator can also check the display of the migration procedure information in S12 and the difference information in S13. If there is a reason why the migration procedure cannot be performed quickly, the operator decides to end the treatment without restarting it. For example, if the migration cannot be performed quickly due to the absence of accessories for installation in the alternative device 3b or because installing accessories would take time, the treatment is ended.

[0159] Next, in the alternative device 3b, the treatment is restarted through the operator's actions (S15). Specifically, the operator operates the screen displayed on the display 13a of the alternative device 3b, thereby initiating the treatment-related operation of the alternative device 3b.

[0160] It should be noted that in the first migration method described above, the patient information migration processing is performed via the portable terminal 5, but it is also possible to perform the patient information migration processing without using the portable terminal 5. That is, the reading unit 19 of the alternative device 3b can read the identification mark displayed on the display 13a of the original device 3a and perform the processing of the calculation unit 21c of the alternative device 3b. Furthermore, the reason for treatment interruption is not limited to a malfunction of the original device 3a, but can also be due to the condition of the hospital 2 or the patient.

[0161] [Second migration method]

[0162] The second migration method differs from the first migration method in that it uses an external storage device to migrate patient information, and the patient information is displayed on the alternative device 3b instead of on the portable terminal 5. Therefore, focusing on the differences from the first migration method, refer to... Figure 10 The processing flow is described, and the description of content that is the same as that of the first migration method is omitted or simplified.

[0163] First, similar to the initial setup (S1, S2), treatment start (S3), treatment interruption (S4), and selection of migration method (S5) in the first migration method, the following steps are performed: initial setup (S21, S22), treatment start (S23), treatment interruption (S24), and selection of migration method (S25). Then, patient information is written to the external recording device (S26). Specifically, when the operator of the original device 3a connects the external recording device to the input / output port of the original device 3a, the control unit 21 of the original device 3a identifies the external recording device. Then, the control unit 21 of the original device 3a reads the patient information from the storage unit 22 and records the patient information to the external recording device via the input / output port 13b.

[0164] Next, the operator of the original device 3a moves the external recording device to the replacement device 3b (T21) and connects the external storage device to the input / output port 13b of the replacement device 3b. As a result, the control unit 21 of the replacement device 3b identifies the external recording device and collects patient information from the external recording device (S27).

[0165] Next, similar to the display of patient information in the first migration method (S8), the patient information collected in the alternative device 3b is displayed on the display 13a (S28). That is, the operator confirms the inherent data and treatment data in the alternative device 3b, which serves as the destination for the migration of patient information, and understands its contents.

[0166] Next, similar to patient information processing (S11), displaying migration procedure information (S12), displaying differential information (S13), migration processing (S14), and treatment restart (S15) in the first migration method, patient information processing (S29), displaying migration procedure information (S30), displaying differential information (S31), migration processing (S32), and treatment restart (S33) are performed.

[0167] It should be noted that in the second migration method described above, information migration is performed by connecting an external storage device to the input / output port of the alternative device 3b. However, the external storage device can also be connected to the input / output port 43b of the hospital server 4, and after the patient information is processed in the hospital server 4, the patient information, differential information, and migration procedure information are sent to the alternative device 3b via the communication line.

[0168] [Third migration method]

[0169] The third migration method differs from the first and second migration methods in that it uses wired or wireless communication to migrate patient information via the hospital server 4; and patient information processing can be performed on the hospital server 4, rather than in the alternative device 3b. Therefore, focusing on the differences from the first and second migration methods, refer to... Figure 11 The processing flow is described, and the description of content that is the same as that of the first and second migration methods is omitted or simplified.

[0170] First, similar to the initial setup (S1, S2), treatment start (S3), treatment interruption (S4), and selection of migration method (S5) in the first migration method, the following steps are performed: initial setup (S41, S42), treatment start (S43), treatment interruption (S44), and selection of migration method (S45). Afterwards, patient information transmission processing (S46) is performed in the original device 3a, and the patient information is sent to the hospital server 4 (T41). Specifically, the control unit 21 of the original device 3a sends the patient information read from the storage unit 22 to the hospital server 4 at the destination via the communication unit 18.

[0171] Next, similar to the blood purification device 3, the information processing unit 47 of the hospital server 4 performs information processing related to the received patient information (S47). Specifically, the processor 47a of the hospital server 4 reads the historical patient information stored in the memory 47b, compares it with the newly received patient information to extract the difference, and generates difference information related to the patient information. Furthermore, the processor 47a also generates migration procedure information representing the migration procedure of the patient information in the replacement device 3b based on the newly received patient information and the generated difference information.

[0172] Next, the information processing unit 47 of the in-hospital server 4 sends patient information, differential information, and migration procedure information to the replacement device 3b (T42) via the communication unit 48. As a result, the control unit 21 of the replacement device 3b receives the patient information via the communication unit 18.

[0173] Next, similar to the display of patient information (S28) in the second migration method, the patient information received in the alternative device 3b is displayed on the display 13a (S48). That is, the operator confirms the inherent data and treatment data in the alternative device 3b, which serves as the destination for the migration of patient information, and understands its contents.

[0174] Next, similar to the display of migration procedure information (S12), display of differential information (S13), migration processing (S14), and treatment restart (S15) in the first migration method, the display of migration procedure information (S49), display of differential information (S50), migration processing (S51), and treatment restart (S52) are performed.

[0175] [Fourth migration method]

[0176] The fourth migration method differs from the first and second migration methods in that it uses wired or wireless communication to migrate patient information via cloud server 7; and patient information processing can be performed on cloud server 7, rather than on alternative device 3b. Therefore, focusing on the differences from the first and second migration methods, refer to... Figure 12 The processing flow is described, and the description of content that is the same as that of the first and second migration methods is omitted or simplified.

[0177] First, similar to the initial setup (S1, S2), treatment start (S3), treatment interruption (S4), and migration method selection (S5) in the first migration method, the following steps are performed: initial setup (S61, S62), treatment start (S63), treatment interruption (S64), and migration method selection (S65). Afterwards, patient information transmission processing (S66) is performed in the original device 3a, and the patient information is sent to the cloud server 7 (T61). Specifically, the control unit 21 of the original device 3a sends the patient information read from the storage unit 22 to the cloud server 7 at the destination via the communication unit 18.

[0178] Next, similar to the blood purification device 3, the information processing unit 77 of the cloud server 7 performs information processing related to the received patient information (S67). Specifically, the processor 77a of the cloud server 7 reads the historical patient information stored in the memory 77b, compares it with the newly received patient information to extract the difference, and generates difference information related to the patient information. Furthermore, the processor 77a also generates migration procedure information representing the migration procedure of the patient information in the replacement device 3b based on the newly received patient information and the generated difference information.

[0179] Next, the information processing unit 77 of the cloud server 7 sends patient information, differential information, and migration procedure information to the replacement device 3b (T62) via the communication unit 78. As a result, the control unit 21 of the replacement device 3b receives the patient information via the communication unit 18.

[0180] Next, similar to the display of patient information in the second migration method (S28), the patient information received in the alternative device 3b is displayed on the display 13a (S68). That is, the operator confirms the inherent data and treatment data in the alternative device 3b, which is the destination of the patient information migration, and understands its contents.

[0181] Next, similar to the display of migration procedure information (S12), display of differential information (S13), migration processing (S14), and treatment restart (S15) in the first migration method, the display of migration procedure information (S69), display of differential information (S70), migration processing (S71), and treatment restart (S72) are performed.

[0182] (Effects of the first implementation method)

[0183] In this embodiment, four migration methods for transferring patient information are stored in the information processing unit 17 of the blood purification device 3. These methods are displayed so that the operator can select the migration method during the initial stage and before the information migration begins. That is, the operator selects any one of the different migration methods used by the blood purification device 3 and the blood purification system 1 to perform the information migration, depending on the environment of the blood purification device 3 and the blood purification system 1.

[0184] Therefore, by employing the optimal migration method corresponding to the state of the blood purification device 3 and the blood purification system 1, or the setup environment of the blood purification device 3 and the blood purification system 1, information migration can be performed easily and accurately, and the lead time until treatment restart can be shortened. In particular, in this embodiment, since the operator selects the migration method, it is easy to reflect the on-site situation of the hospital 2, enabling more accurate information migration. Furthermore, since it is not necessary to input various information related to the migration of the patient and the blood purification device 3 into the blood purification device 3, human errors such as input errors are avoided, and the overall processing time can be reduced.

[0185] <Second Implementation Method>

[0186] In the first embodiment, the operator of the blood purification device 3 selects the patient information transfer method twice. However, the blood purification device 3 may also automatically select the transfer method based on predetermined information. That is, the control unit 21 of the blood purification device 3 may generate control unit selection information and select any one of the first to fourth transfer methods based on this control unit selection information to perform the patient information transfer process. This is referred to as the second embodiment. Figures 13 to 15 Let's explain. Here, Figure 13 This is a functional block diagram related to information migration of the blood purification device 3 (original device 3a) involved in the second embodiment. Figure 14 This is a timing diagram related to information migration in the blood purification system 1 according to the second embodiment. Figure 15 This is a flowchart related to the selection of the migration method in the blood purification device 3 (original device 3a) according to the second embodiment. It should be noted that the parts that are different from those in the first embodiment are basically described, and the descriptions of the same content are omitted. The reference numerals in the drawings are also basically the same.

[0187] First, such as Figure 13 As shown, the control unit 21 of the information processing apparatus 17 includes an identification mark generation unit 21b, an arithmetic unit 21c, and a selection information generation unit 21d. That is, unlike the first embodiment, the control unit 21 does not include a selection image generation unit 21a for generating an image for the operator to select, but instead includes a selection information generation unit 21d for selecting a migration method. Similar to the first embodiment, these components are implemented by the processor 17a and memory 17b of the information processing apparatus 17 themselves, or by the processor 17a reading and executing a program stored in the memory 17b.

[0188] like Figure 13As shown, when the blood purification device 3, which serves as the information migration source, i.e., the original device 3a, causes the treatment to be interrupted due to a malfunction or other reasons, the control unit 21 generates a response confirmation message and sends it to the communication unit 18. Figure 13 A in the text: Response confirmation information). This response confirmation information is sent to the portable terminal 5 via the communication unit 18. When the operator responds in the portable terminal 5, the response information is replied to the control unit 21 via the communication unit 18. Figure 13 B in the text: Response information.

[0189] Here, the response information refers to information related to the operator's ability to handle information migration-related processes. For example, consider information related to the operator's ability to handle information migration processes. That is, if the operator is unable to perform information migration processes due to other business operations, it is necessary to avoid selecting the first and second migration methods. Such information is needed to prevent the selection of migration methods that require operator intervention in situations where the operator is unable to handle the situation.

[0190] Next, the information generation unit 21d receives four migration method data, setting environment information, and status information of the patient information stored in the storage unit 22 from the storage unit 22. Figure 13 The C in the diagram represents migration method data, setup environment information, and status information. Based on this information, control unit selection information is generated. This control unit selection information then becomes the final selection information used to determine the migration method. It should be noted that the setup environment information and status information are updated periodically or at appropriate times based on update information input via the display 13a, input / output port 13b, or communication unit 18.

[0191] Here, the environment setting information is information related to the environment in which the original device 3a and the replacement device 3b are set. For example, it is envisioned that this information relates to whether a communication line can be used, and whether there is a reading device or external storage device, such as the portable terminal 5. That is, if the communication line is unusable, it is necessary to avoid selecting the third and fourth migration methods. Such information is needed to avoid selecting migration methods related to devices that cannot be used in the initial setting state. In addition, the status information is information related to the usage status of the original device 3a and the replacement device 3b. For example, it is envisioned that this information relates to malfunctions of the display 13a, input / output port 13b, communication unit 18, and reading unit 19. In addition, it is also envisioned that this information relates to the speed of the communication line and whether it can be connected to servers inside or outside the facility. That is, if the display 13a malfunctions, it is necessary to avoid selecting the first migration method. Such information is needed to avoid selecting migration methods related to malfunctioning devices.

[0192] In summary, the environmental information, status information, and response information are used to determine whether the first to fourth migration methods can be performed in the environment in which the blood purification device 3 is set up and used.

[0193] When the final method of information migration is selected by the selection information generation unit 21d, the control unit 21 receives the patient information stored in the storage unit 22 from the storage unit 22. Figure 13 D in the text refers to patient information. Furthermore, the control unit 21 performs patient information migration processing based on the selected information migration method. Specifically, when the first migration method using identification tags is selected, the identification tag generation unit 21b generates an identification tag corresponding to the patient information and sends the identification tag to the display 13a. Figure 13 E1 in the text: identification mark), causing the display 13a to show the identification mark. If the second migration method utilizing an external storage device is selected, the control unit 21 sends the received patient information to the input / output port 13b (…). Figure 13 E2: Patient Information), so that the external storage device connected to input / output port 13b stores the patient information. If the third or fourth migration method using the hospital server 4 or cloud server 7 is selected, the control unit 21 sends the received patient information to the destination server via the communication unit 18. Figure 13 E3 in the document: Patient Information.

[0194] It should be noted that, in the case where the blood purification device 3 is a replacement device 3b serving as the destination for information migration, due to the... Figure 13 The structure shown is the same as, and is the same as Figure 5 The information shown follows the same flow, so its description is omitted.

[0195] Next, refer to Figure 14 The processing related to the migration of patient information in the blood purification system 1 according to this embodiment will be described. It should be noted that the processing up to the selection of the migration method is different from that in the first embodiment, but the migration method itself is the same. Therefore, the following description will take the case where the first migration method is selected as an example, and the description of the case where other migration methods are selected will be omitted.

[0196] First, such as Figure 14 As shown, treatment begins in a blood purification device 3 (S101). Subsequently, the blood purification device 3 malfunctions for some reason, interrupting the treatment in the original device 3a (S102). It should be noted that these steps are the same as S3 and S4 of the first embodiment.

[0197] Next, when the control unit 21 of the original device 3a detects a treatment interruption, the control unit 21 generates a response confirmation message and sends the response confirmation message to the portable terminal 5 (T101) via the communication unit 18. For example, the response confirmation message may also include inquiry information related to whether the patient information transfer processing can be handled.

[0198] Next, in the portable terminal 5, processing is performed to generate response information related to whether or not the received response confirmation information can be handled. Specifically, in the portable terminal 5 held by the operator, the operator operates the screen displayed on the display 53a, thereby generating response information corresponding to the operation by the information processing device 57 of the portable terminal 5. Then, the information processing device 57 of the portable terminal 5 replies the generated response information to the original device 3a via the communication unit 58 (T102).

[0199] Next, when the control unit 21 of the original device 3a receives the response information, it performs a migration method selection process in the original device 3a (S104). Specifically, the selection information generation unit 21d of the original device 3a reads the four migration method data, setting environment information, and status information of the patient information stored in the storage unit 22. Then, based on the received response information and the read migration method data, setting environment information, and status information, the selection information generation unit 21d of the original device 3a generates control unit selection information, which becomes the final selection information for determining the migration method.

[0200] Here, refer to Figure 15 An example of a specific method for generating selection information in a control unit will be explained. Specifically, the selection information generation unit 21d, based on the received and read information and data, performs [further processing / interaction]. Figure 15 The process involves handling related procedures and making selections related to patient information migration.

[0201] First, the selection information generation unit 21d determines whether the environment is suitable for using a communication line (S151). This determination is based on the setting environment information read from the storage unit 22.

[0202] Next, if the condition in S151 is yes, the selection information generation unit 21d determines whether the speed of the communication line is above the specified limit (S152). Next, if the condition in S152 is yes, the selection information generation unit 21d determines whether it is possible to connect to the on-site server 4 (S153). These determinations are based on the status information read from the storage unit 22. Then, if the condition in S153 is yes, the selection information generation unit 21d generates control unit selection information indicating the selection of the third migration method (S154).

[0203] On the other hand, if the result in S153 is no, it is determined whether it is possible to connect to the cloud server 7, which is an off-site server (S155). This determination is based on the status information read from the storage unit 22. Then, if the result in S155 is yes, the selection information generation unit 21d generates control unit selection information indicating that the fourth migration method is selected (S156).

[0204] Furthermore, if S151 or S152 is negative, it is determined whether the operator can handle the migration process (S157). This determination is based on the received response information. Next, if S157 is positive, the selection information generation unit 21d determines whether the display 13a can be used (S158). This determination is based on the read status information. Then, if S158 is positive, the selection information generation unit 21d generates control unit selection information indicating that the first migration method is selected (S159).

[0205] On the other hand, if the result in S158 is negative, it is determined whether the input / output port 13b can be used (S160). This determination is based on the status information read from the storage unit 22. Then, if the result in S160 is positive, the selection information generation unit 21d generates control unit selection information indicating that the second migration method is selected (S161).

[0206] If the error is not found in S157 or S160, since the communication line is also unusable and the operator is unable to respond, the selection information generation unit 21d determines that the patient information transfer process cannot be performed, and generates control selection information indicating the intention to end treatment (S162). Here, the control selection information indicating the intention to end treatment is displayed as a suggestion or recommendation on the display 13a of the original device 3a.

[0207] It should be noted that the above process is ultimately an example, and the order of each decision can be changed. That is, the order of each decision can be appropriately set so that any of the first to fourth migration methods can be selected first. Furthermore, the selection of the information generation unit 21d can also be omitted. Figure 15 Instead of the judgment shown, it uses an AI judgment unit that performs machine learning by utilizing response information, four types of transfer method data, setting environment information, and state information to extract the best method corresponding to the situation when performing information transfer.

[0208] Return to Figure 14In the original device 3a, the process of displaying the identification mark is performed in the same way as in S6 of the first embodiment (S105). Next, in the portable terminal 5, the process of taking a picture (S106), displaying patient information (S107), and displaying the identification mark (S108) are performed in the same way as in S7 to S9 of the first embodiment. Afterwards, in the alternative device 3b, the process of taking a picture (S109), processing patient information (S110), displaying transfer procedure information (S111), displaying differential information (S112), transfer processing (S113), and restarting treatment (S114) are performed in the same way as in S10 to S15 of the first embodiment.

[0209] It should be noted that in this embodiment, a response confirmation was sent to the portable terminal 5, but the migration method can also be selected without such a response confirmation. That is, when selecting a migration method, the operator's ability to handle the relevant information can be disregarded, and the migration method can be selected based solely on other information.

[0210] (Effects of the second implementation method)

[0211] Similarly, in this embodiment, four migration methods for patient information migration are stored in the information processing unit 17 of the blood purification device 3, and the information processing unit 17 automatically selects the migration method before the information migration is to be performed. That is, based on the environment of the blood purification device 3 and the blood purification system 1, any one of the migration methods used by the equipment is automatically selected, and the information migration is performed automatically.

[0212] Therefore, the optimal migration method corresponding to the state of the blood purification device 3 and the blood purification system 1, or the setup environment of the blood purification device 3 and the blood purification system 1, can be automatically selected, enabling easy and accurate information migration and shortening the lead time until treatment restart. In particular, in this embodiment, since the information processing device 17 automatically selects the migration method and the information migration proceeds automatically, faster and more accurate information migration is possible. Furthermore, since it is not necessary to input various information related to the migration of the patient and the blood purification device 3 into the blood purification device 3, human errors such as input errors are avoided, and the overall processing time is reduced.

[0213] <Third Implementation Method>

[0214] In the first and second embodiments, the method for transferring patient information is determined by the selection of either the operator of the blood purification device 3 or the control unit 21 of the blood purification device 3. However, the operator may also make the selection at the initial stage, and the control unit 21 may make the final selection just before the information transfer. That is, initial selection information including at least one of the first to fourth transfer methods may be generated through the operator's selection, and the control unit 21 generates control unit selection information that becomes the final selection information based on the initial selection information, the setup environment information of the blood purification device 3, the status information of the blood purification device 3, and the operator's response information. This is referred to as the third embodiment. Figure 16 and Figure 17 To explain. Here, Figure 16 This is a functional block diagram related to information migration of the blood purification device 3 according to the third embodiment. Figure 17 This is a timing diagram related to information migration in the blood purification system 1 according to the third embodiment. It should be noted that the parts that are different from the first and second embodiments are basically described, and the descriptions of the same content are omitted. The reference numerals in the drawings are also basically the same.

[0215] First, such as Figure 16 As shown, the control unit 21 of the information processing apparatus 17 in this embodiment includes a selection image generation unit 21a, a recognition mark generation unit 21b, a calculation unit 21c, and a selection information generation unit 21d. That is, unlike the first and second embodiments, the control unit 21 includes both a selection image generation unit 21a for generating an image for the operator to select and a selection information generation unit 21d for selecting a migration method. Similar to the first and second embodiments, these components are implemented by the processor 17a and memory 17b of the information processing apparatus 17 themselves, or by the processor 17a reading and executing a program stored in the memory 17b.

[0216] like Figure 16 As shown, when the blood purification device 3 is the original device 3a serving as the information transfer source, the image generation unit 21a receives data from the storage unit 22 using four transfer methods to obtain patient information stored in the storage unit 22. Figure 16 In the A section (migration method data), an initial selection image is generated for the operator to select a migration method in the initial stage. Furthermore, the selection image generation unit 21a sends the generated initial selection image to the display 13a (…). Figure 16 B in the image selection unit 21a receives initial selection information input from the display 13a by the operator of the blood purification device 3 through operation of the display 13a. Figure 16C in the image generation unit 21a then sends the received initial selection information to the storage unit 22. Figure 16 The initial selection information (D in the text) is stored in the storage unit 22.

[0217] Subsequently, when the blood purification device 3, which serves as the information migration source, causes the treatment to be interrupted due to a malfunction or other reasons, the control unit 21 generates a response confirmation message and sends it to the communication unit 18. Figure 16 E in the text: Response confirmation information. This response confirmation information is sent to the portable terminal 5 via the communication unit 18. When the operator responds in the portable terminal 5, the response information is replied to the control unit 21 via the communication unit 18. Figure 16 F in the text: Response information.

[0218] Next, the selection information generation unit 21d receives the initial selection information, setting environment information, and status information stored in the storage unit 22 from the storage unit 22. Figure 16 In the G section, initial selection information, environment setup information, and status information are used to generate control unit selection information based on response information, initial selection information, environment setup information, and status information. This control unit selection information then becomes the final selection information used to determine the migration method.

[0219] When the final method of information migration is selected by the selection information generation unit 21d, the control unit 21 receives the patient information stored in the storage unit 22 from the storage unit 22. Figure 16 H in the text refers to patient information. Furthermore, the control unit 21 performs patient information migration processing based on the selected information migration method. Figure 16 J1: Identification marker, J2: Patient information, J3: Patient information (in this context).

[0220] It should be noted that, in the case where the blood purification device 3 is a replacement device 3b serving as the destination for information migration, due to the... Figure 16 The structure shown is the same as, and is the same as Figure 5 The information shown follows the same flow, so its description is omitted.

[0221] Next, refer to Figure 17 The processing related to the migration of patient information in the blood purification system 1 according to this embodiment will be described. It should be noted that the processing up to the selection of the migration method is different compared with the first and second embodiments, but the migration method itself is the same. Therefore, the following description takes the case where the first migration method is selected as an example, and the description of the case where other migration methods are selected is omitted.

[0222] First, similar to the initial setting (S1, S2), treatment start (S3), and treatment interruption (S4) in the first embodiment, the initial setting (S201, S202), treatment start (S203), and treatment interruption (S204) are performed in the original device 3a and the alternative device 3b.

[0223] Next, similar to the response confirmation (T101) in the second embodiment, the control unit 21 generates response confirmation information and sends it to the portable terminal 5 via the communication unit 18 (T201). Then, similar to the generation (S103) and reply (T102) of response information in the second embodiment, the portable terminal 5 performs processing to generate and reply to response information related to whether or not the received response confirmation information can be responded to (S205, T202).

[0224] Next, when the control unit 21 of the original device 3a receives the response information, it performs a migration method selection process in the original device 3a (S206). Specifically, the selection information generation unit 21d of the original device 3a reads the initial selection information, setting environment information, and status information stored in the storage unit 22. Then, based on the received response information and the read initial selection information, setting environment information, and status information, the selection information generation unit 21d of the original device 3a generates control unit selection information, which becomes the final selection information used to determine the migration method.

[0225] Regarding this selection process, it can be implemented in the second embodiment. Figure 15 Based on the illustrated process, the decision process is executed by modifying it to prioritize the initial selection of the migration method. Alternatively, the selection information generation unit 21d may not follow this decision process, but instead utilize an AI decision unit that employs machine learning based on response information, data from the four migration methods, setting environment information, state information, and initial selection information to extract the optimal method corresponding to the situation during information migration.

[0226] In the original device 3a, the process of displaying the identification mark is performed in the same way as in S6 of the first embodiment (S207). Next, in the portable terminal 5, the process of taking a picture (S208), displaying patient information (S209), and displaying the identification mark (S210) are performed in the same way as in S7 to S9 of the first embodiment. Afterwards, in the alternative device 3b, the process of taking a picture (S211), processing patient information (S212), displaying transfer procedure information (S213), displaying differential information (S214), transfer processing (S215), and restarting treatment (S216) are performed in the same way as in S10 to S15 of the first embodiment.

[0227] (Effects of the third implementation method)

[0228] In this embodiment, four migration methods for patient information are stored in the information processing unit 17 of the blood purification device 3. The operator selects the migration method in the initial stage, and the information processing unit 17 automatically determines the final migration method just before the information migration is to be performed. That is, based on the environment of the blood purification device 3 and the blood purification system 1, any one of the different migration methods used by the equipment is selected for information migration.

[0229] Therefore, by employing the optimal migration method corresponding to the state of the blood purification device 3 and the blood purification system 1, or the setup environment of the blood purification device 3 and the blood purification system 1, information migration can be performed easily and accurately, and the lead time until treatment restart can be shortened. In particular, in this embodiment, the operator selects the migration method at the initial stage, allowing multiple methods adapted to the environment of the blood purification device 3 and the blood purification system 1 to be selected. Furthermore, the information processing device 17 automatically selects the final migration method, and the information migration proceeds automatically. Thus, while reflecting the on-site situation of the hospital 2, more rapid and accurate information migration can be performed. In addition, since it is not necessary to input various information related to the migration of the patient and the blood purification device 3 into the blood purification device 3, human errors such as input errors are avoided, and the overall processing time can be reduced.

[0230] <Fourth Implementation Method>

[0231] In the third embodiment, the operator makes the initial selection, and the control unit 21 makes the final selection; however, the reverse is also possible. That is, the control unit 21 may make the initial selection, enabling the display of recommended migration methods, and the operator may make the final selection. This is referred to as the fourth embodiment. Figure 18 and Figure 19 To explain. Here, Figure 18 This is a functional block diagram related to information migration of the blood purification device 3 (original device 3a) involved in the fourth embodiment. Figure 19 This is a timing diagram related to information migration in the blood purification system 1 according to the fourth embodiment. It should be noted that the parts that are different from those in the first to third embodiments are basically described, and the descriptions of the same content are omitted. The reference numerals in the drawings are also basically the same.

[0232] First, such as Figure 18As shown, the control unit 21 of the information processing apparatus 17 in this embodiment includes a selection image generation unit 21a, a recognition mark generation unit 21b, a calculation unit 21c, and a selection information generation unit 21d. That is, unlike the first and second embodiments, the control unit 21 includes both a selection image generation unit 21a for generating an image for the operator to select and a selection information generation unit 21d for selecting a migration method. Similar to the first and second embodiments, these components are implemented by the processor 17a and memory 17b of the information processing apparatus 17 themselves, or by the processor 17a reading and executing a program stored in the memory 17b.

[0233] like Figure 18 As shown, when the blood purification device 3 is the original device 3a serving as the information migration source, the information generation unit 21d receives data on four migration methods of patient information stored in the storage unit 22, as well as setting environment information, from the storage unit 22. Figure 18 In the data set, A represents migration method data and setup environment information. Based on the received data and information, control unit selection information is generated. This control unit selection information then becomes the initial selection information used to determine the migration method.

[0234] Subsequently, when the original device 3a, which is the blood purification device 3, causes the treatment to be interrupted due to malfunction or other reasons, the selection image generation unit 21a receives the initial selection information stored in the storage unit 22 from the storage unit 22. Figure 18 (B: Initial Selection Information), and generates a final selection image for the operator to select a migration method during the actual information migration phase. Furthermore, the selection image generation unit 21a sends the generated final selection image to the display 13a ( Figure 18 C in the text: Final image selection). Furthermore, the image generation unit 21a receives operator selection information input from the display 13a by the operator of the blood purification device 3 through operation of the display 13a. Figure 18 D in the text: Operator selection information).

[0235] When the final method for information migration is selected, the control unit 21 receives the patient information stored in the storage unit 22 from the storage unit 22. Figure 18 E in the text refers to patient information. Furthermore, the control unit 21 performs patient information migration processing based on the selected information migration method. Figure 18 (In the image: F1: Identification marker, F2: Patient information, F3: Patient information).

[0236] It should be noted that, in the case where the blood purification device 3 is a replacement device 3b serving as the destination for information migration, due to the... Figure 18 The structure shown is the same as, and is the same as Figure 5 The information shown follows the same flow, so its description is omitted.

[0237] Next, refer to Figure 19 The processing related to the migration of patient information in the blood purification system 1 according to this embodiment will be described. It should be noted that the processing up to the selection of the migration method is different compared with the first to third embodiments, but the migration method itself is the same. Therefore, the following description will take the case where the first migration method is selected as an example, and the description of the case where other migration methods are selected will be omitted.

[0238] First, such as Figure 19 As shown, in each blood purification device 3 (original device 3a and replacement device 3b), initial settings related to information migration are performed (S301 and S302). The selection information generation unit 21d of the original device 3a and replacement device 3b reads the migration method data and setting environment information stored in the storage unit 22. Then, based on these data and information, the selection information generation unit 21d generates control unit selection information, which becomes the initial selection information for determining the migration method.

[0239] Regarding this selection process, it can be implemented in the second embodiment. Figure 15 Based on the illustrated process, the decision-making process is modified to remove the decision-making based on state information and response information. In this case, multiple migration methods can be selected instead of just one. Furthermore, the information generation unit 21d can also deviate from this decision-making process and instead use an AI decision-making unit that performs machine learning using data from the four migration methods and setting environment information to extract at least one optimal method corresponding to the situation when performing information migration.

[0240] Next, similar to S3-S6 in the first embodiment, in the original device 3a, treatment initiation (S303), treatment interruption (S304), selection of migration method (S305), and display of identification mark (S306) are performed. Next, in the portable terminal 5, similar to S7-S9 in the first embodiment, image capture processing (S307), patient information display processing (S308), and identification mark display processing (S309) are performed. Then, in the alternative device 3b, similar to S10-S15 in the first embodiment, image capture processing (S310), patient information processing (S311), display of migration procedure information (S312), display of differential information (S313), migration processing (S314), and treatment restart processing (S315) are performed.

[0241] (Effects of the fourth implementation method)

[0242] In this embodiment, four migration methods for patient information are stored in the information processing unit 17 of the blood purification device 3. The information processing unit 17 automatically selects the migration method in the initial stage, and the operator makes the final determination of the migration method just before the information migration is to be performed. That is, based on the environment of the blood purification device 3 and the blood purification system 1, any one of the different migration methods used by the equipment is selected for information migration.

[0243] Therefore, by employing the optimal migration method corresponding to the state of the blood purification device 3 and the blood purification system 1, or the setup environment of the blood purification device 3 and the blood purification system 1, information migration can be performed easily and accurately, and the lead time until treatment restart can be shortened. In particular, in this embodiment, since the migration method is automatically selected by the information processing device 17 at the initial stage, the operator can more easily and quickly select the information migration method just before the information migration is to be performed, reflecting the on-site situation of the hospital 2. Furthermore, since it is not necessary to input various information related to the migration of the patient and the blood purification device 3 into the blood purification device 3, human errors such as input errors are avoided, and the overall processing time can be reduced.

[0244] <Implementation Plan of this Disclosure>

[0245] The first embodiment of this disclosure is a blood purification device that purifies a patient's blood and includes: a storage unit for storing patient information, including the patient's intrinsic data and treatment data; an output unit for outputting the patient information to an external location via an information acquisition device used by the operator of the blood purification device; a communication unit for transmitting the patient information to an external location using a communication line; and a control unit for controlling either the output unit or the communication unit to perform the transfer of the patient information.

[0246] In this way, by choosing to use any of the different migration methods of the device for information migration, the optimal migration method corresponding to the state or setting environment of the blood purification device can be adopted, making information migration easy and accurate, and shortening the lead time until treatment restart.

[0247] The second embodiment of this disclosure, based on the first embodiment, includes an output unit comprising a display showing the patient information as an identification marker and an output port for connection to the information acquisition device. The patient information is output via either the display or the output unit. The communication unit transmits the patient information to an in-facility server or an external server via a communication line. The in-facility server is located within the facility where the blood purification device is installed, and the external server is located outside the facility. This allows for more detailed consideration of the equipment used for information migration, thus enabling easier and more accurate information migration while shortening the lead time until treatment restart.

[0248] The third embodiment of this disclosure, based on the second embodiment, involves an information acquisition device that reads the identification tag or an external storage device connected to the output port. The control unit, based on the final selection information, determines one of the following migration methods: a first migration method, generating the identification tag and displaying it on the display, then performing information migration by reading it through the reading device; a second migration method, storing the patient information in the external storage device via the output unit; a third migration method, sending the patient information to an in-facility server via the communication unit; and a fourth migration method, sending the patient information to an external server via the communication unit.

[0250] The fifth embodiment of this disclosure, based on the fourth embodiment, involves the storage unit storing initial selection information, which includes at least one of the first to fourth migration methods initially selected by the operator. Before the patient information is migrated, the control unit displays a final selection image of the migration method on the display based on the initial selection information and acquires the operator's selection information. Thus, by having an operator familiar with the environment of the blood purification device select the migration method in stages, optimal information migration can be performed easily and quickly.

[0251] The sixth embodiment of this disclosure, based on the fourth embodiment, includes a storage unit storing initial selection information. This initial selection information includes at least one of the first to fourth migration methods initially selected by the operator. The control unit generates control selection information based on the initial selection information, the setup environment information of the blood purification device, the status information of the blood purification device, and the operator's response information. Because the initial selection is made by a person familiar with the environment of the blood purification device, and the migration method is automatically selected by the device before information migration, information migration can be performed easily and quickly.

[0252] The seventh embodiment of this disclosure, based on the fourth embodiment, involves the control unit generating initial selection information for at least one of the first to fourth migration methods based on the environmental information of the blood purification device, and storing this initial selection information in the storage unit. Before the patient information is migrated, the control unit displays the final selection image of the migration method on the display based on the initial selection information and obtains the operator's selection information. Thus, the device, which is familiar with the environment of the blood purification device, automatically selects the migration method, enabling easy and rapid information migration.

[0253] Based on any of the second to seventh embodiments, the eighth embodiment of this disclosure displays other patient information transferred from other blood purification devices on the display screen. This allows for easy access to the transferred patient information, thus enabling easy and rapid information transfer.

[0254] Based on any of the second to eighth embodiments, the ninth embodiment of this disclosure, using the other patient information, generates migration procedure information for restarting the patient's treatment and displays the migration procedure information on the display. This allows for easy understanding of the migration procedure, thus enabling easy and rapid information migration.

[0255] Based on any of the second to ninth embodiments, the tenth embodiment of this disclosure compares the patient information stored in the storage unit with other patient information transferred from the other blood purification device to extract differential information, and displays the differential information on the display. Therefore, in information transfer-related processing, content different from the previous information can be easily grasped, thus enabling easy and rapid information transfer.

[0256] The eleventh embodiment of this disclosure, based on any one of the second to tenth embodiments, includes: a reading unit for reading the identification mark displayed as other patient information; and an input port for connecting to the information acquisition device storing the other patient information to input the other patient information. Thus, patient information can be transferred using two blood purification devices, enabling easy and rapid information transfer.

[0257] The twelfth embodiment of this disclosure is a blood purification system comprising: a first blood purification device for purifying a patient's blood; a second blood purification device selected as an alternative to the first blood purification device; and a server connected to the first and second blood purification devices via a communication line. The first blood purification device comprises: a storage unit for storing patient information, including the patient's intrinsic data and treatment data; an output unit for outputting the patient information to an external location via an information acquisition device used by an operator of the first blood purification device; a communication unit for sending the patient information to the server via the communication line; and a control unit for controlling either the output unit or the communication unit to perform processing for migrating the patient information to the second blood purification device. Thus, by selecting any of the different migration methods used for information migration, the optimal migration method corresponding to the state or setup environment of the blood purification device can be employed, enabling easy and accurate information migration and shortening the lead time until treatment restart.

[0258] The thirteenth embodiment of this disclosure, based on the twelfth embodiment, involves the server generating migration procedure information for restarting the patient's treatment in the second blood purification device, and differential information between the first and second blood purification devices, based on the patient information received from the first blood purification device and the historical patient information from the second blood purification device. The server then sends the migration procedure information and the differential information to the second blood purification device. This allows for easy access to the migrated patient information, migration procedure, and any previously different information related to the migration, thus enabling easy and rapid information migration.

[0259] The fourteenth embodiment of this disclosure is an information migration method for migrating patient information from a blood purification device that purifies a patient's blood. This information migration method includes: a step of storing the patient information, including the patient's inherent data and treatment data, in a storage unit of the blood purification device; a step of selecting either an operator-interventional migration method or a communication-based migration method, wherein in the operator-interventional migration method, the patient information is output to an external location via an information acquisition device used by the operator of the blood purification device for information migration, and in the communication-based migration method, the patient information is transmitted to an external location using a communication line for information migration; and a step of migrating the patient information based on the selected migration method. Thus, by selecting either an operator-interventional migration method or a communication-based migration method with different equipment for information migration, the optimal migration method corresponding to the state or setup environment of the blood purification device can be adopted, enabling easy and accurate information migration and shortening the lead time until treatment restart.
