[0001] The present disclosure relates to a dialysis system and an information processing method. [Background technology]

[0002] Conventionally, a system including a medical treatment unit and a peripheral device is known. For example, Japanese Patent Application Laid-Open No. 2017-63974 (Patent Document 1) discloses a dialysis system including a dialysis device as a medical treatment unit and a terminal device as a peripheral device.

[0003] Specifically, JP 2017-63974 A discloses that "a bedside terminal is placed at the bedside of a dialysis patient, and information indicating the progress of dialysis including the patient's vital signs provided by the dialysis machine is displayed on this bedside terminal, and when requested by the bedside terminal, both information or services using various amenities, the internet or the medical institution's system, and the information indicating the progress of dialysis are displayed" ("Abstract").

Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following description, the same members are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated.

[0013] <A. System Configuration> Fig. 1 is a diagram showing a dialysis system according to the present embodiment. As shown in Fig. 1, the dialysis system 1 includes a management device 100, a weighing scale 200, a plurality of dialysis devices 300 (301, 302, ...), a portable terminal device 400, a hub 500, a wireless access point 600, and a server device 900. For the sake of simplicity, only one terminal device 400 is illustrated, but the number of terminal devices is not limited to this.

[0014] In this example, the management device 100 corresponds to the "information processing device" of the present invention. An example in which the server device 900 corresponds to the "information processing device" of the present invention will be described in a modified example. The terminal device 400 corresponds to the "first terminal device" of the present invention.

[0015] The management device 100 is operated by a medical professional such as a nurse. The management device 100 is typically a personal computer. The terminal device 400 is operated by a dialysis patient. The terminal device 400 is typically a smartphone. The terminal device 400 is not limited to this and may be a tablet terminal or the like. The terminal device 400 is typically owned by the dialysis patient. The terminal device 400 is not limited to this and may be an item loaned to the dialysis patient by a hospital or the like.

[0016] The weighing scale 200 is directly connected to the management device 100 so as to be able to communicate with each other. The management device 100 is connected to a hub 500 so as to be able to communicate with each other. Each dialysis device 300 is also connected to the hub 500 so as to be able to communicate with each other. The hub 500 is connected to a wireless access point 600 so as to be able to communicate with each other. The wireless access point 600 is a device for connecting to the network NW. The terminal device 400 is able to communicate with the wireless access point 600.

[0017] The management device 100 and each dialysis device 300 are communicatively connected to the server device 900 via the hub 500, the wireless access point 600, and the network NW. The terminal device 400 is communicatively connected to the server device 900 via the wireless access point 600 and the network NW. The network NW is typically the Internet. If the wireless access point 600 has a hub function, the hub 500 is not required.

[0018] In the following, a case where the server device 900 functions as a relay device will be described. Specifically, a configuration will be described in which communication between the management device 100 and each dialysis device 300 and communication between the management device 100 and the terminal device 400 are once routed through the server device 900.

[0019] The management device 100 includes a main body 101, a display 102, an input device 103, and a reader / writer 104. The main body 101 has a processor and a memory in which an operating system and various programs are stored. The display 102, the input device 103, and the reader / writer 104 are communicatively connected to the main body 101. In this example, the main body 101 is connected to the hub 500 by wire.

[0020] The reader / writer 104 is a device for near field communication (NFC). The reader / writer 104 has a control board and an antenna, not shown. Instead of the reader / writer 104, a reader (card reader) without a writer function may be used.

[0021] Weighing scale 200 includes main body 201, display 202, and reader / writer 204. Weighing scale 200 measures the weight of a dialysis patient standing on main body 201. The measured weight is displayed on display 202. Weighing scale 200 transmits the measured weight to management device 100.

[0022] The display 202 and the reader / writer 204 are communicably connected to the main body 201. The main body 201 is connected to the main body 101 of the management device 100. In this example, the main body 201 is connected to the main body 101 by wire. The reader / writer 204 has the same configuration as the reader / writer 104.

[0023] Each dialysis device 300 includes a main body 351, a display 352, and a reader / writer 354. The main body 351 includes various pumps and the like. The display 352 and the reader / writer 354 are connected to the main body 351. In this example, the main body 351 is connected to the hub 500 by wire. Each dialysis device 300 transmits vital information indicating the vital signs of the dialysis patient and the like to the management device 100 via the hub 500 and the server device 900.

[0024] The terminal device 400 has a touch screen 402. The terminal device 400 performs communication via the wireless access point 600. In addition to this, the terminal device 400 can perform short-range wireless communication with the management device 100, the weighing scale 200, and each dialysis device 300. The short-range wireless communication is performed to authenticate (personal authentication) the dialysis patient.

[0025] Specifically, the terminal device 400 incorporates a contactless integrated circuit card. The contactless integrated circuit card has an integrated circuit chip and an antenna. When the dialysis patient brings the terminal device 400 close to the reader / writer 104 of the management device 100, the terminal device 400 performs short-range wireless communication with the management device 100.

[0026] Similarly, when the dialysis patient brings the terminal device 400 close to the reader / writer 204 of the weighing scale 200, the terminal device 400 performs short-range wireless communication with the weighing scale 200. When the dialysis patient brings the terminal device 400 close to the reader / writer 354 of the dialysis device 300, the terminal device 400 performs short-range wireless communication with the dialysis device 300.

[0027] <B. Dialysis Room> FIG. 2 is a top view (sketch) of the dialysis room in the hospital. As shown in FIG. 2, in the dialysis room 20, a plurality of beds 701 to 709 are installed. Hereinafter, any one of the beds 701 to 709 is also referred to as "bed 700". Next to each bed 700, one dialysis device 300 is installed. Next to the beds 701 to 709, dialysis devices 301 to 309 are installed respectively.

[0028] In the dialysis room 20, a counter 800 and a weighing scale 200 are further installed. On the counter 800, a management device 100 is placed. As described above, the management device 100 has a reader / writer 104. The weighing scale 200 has a reader / writer 204. Each dialysis device 300 has a reader / writer 354.

[0029] Although details will be described later, when a dialysis patient enters the dialysis room 20, the patient brings the terminal device 400 close to the reader / writer 104 of the management device 100. Thereby, the management device 100 performs personal authentication of the dialysis patient. Thereafter, body weight measurement and dialysis are performed in order.

[0030] In the dialysis system 1, in addition to the above personal authentication, personal authentication is also performed before body weight measurement and before dialysis. Specifically, personal authentication using the reader / writer 204 of the weighing scale 200 and personal authentication using the reader / writer 354 of the dialysis device 300 are performed.

[0031] Thus, in the dialysis system 1, three times of personal authentication are performed before starting dialysis for the dialysis patient. Hereinafter, the three times of personal authentication will be described.

[0032] <C. Flow of Processing> FIG. 3 is a sequence diagram showing the first half of the processing flow in the dialysis system 1. FIG. 4 is a sequence diagram showing the second half of the processing flow in the dialysis system 1.

[0033] 3, when a dialysis patient (hereinafter also referred to as "patient S to be treated") who has entered the dialysis room 20 brings the terminal device 400 close to the reader / writer 104 of the management device 100, in sequence SQ1, the terminal device 400 transmits a patient ID (identification) of the patient S to be treated by short-range wireless communication to the management device 100. The patient ID (second identification information) is stored in advance in the memory of the terminal device 400.

[0034] In sequence SQ2, the management device 100 performs personal authentication (patient authentication) of the treatment target patient S using the patient ID received from the terminal device 400. Specifically, the management device 100 identifies the treatment target patient S from among a plurality of registered patients who have been registered in advance. The management device 100 displays the authentication result (patient name, etc.) on the display 102. This allows the nurse to visually confirm the authentication result. Furthermore, the management device 100 also displays the bed number on the display 102.

[0035] In detail, the management device 100 stores patient information Q (FIG. 11) for each dialysis patient. The patient information includes a patient ID (first identification information). From among the multiple patient IDs, the management device 100 selects a patient ID that matches the patient ID received from the terminal device 400 via short-range wireless communication. Next, the management device 100 identifies, from among the multiple dialysis patients, a dialysis patient having the selected patient ID (i.e., the patient S to be treated).

[0036] In sequence SQ3, the management device 100 transmits the authentication result to the terminal device 400 by short-distance wireless communication. Note that a series of processes from sequence SQ1 to sequence SQ3 are performed instantaneously. At the time of sequence SQ3, the terminal device 400 maintains a state in which it is close to the reader / writer 104 of the management device 100.

[0037] In sequence SQ4, the terminal device 400 displays the received authentication result on the touch screen 402. This allows the treatment target patient S to confirm that he or she has been authenticated.

[0038] The above authentication process completes the reception process for the treatment target patient S. According to the dialysis system 1, the reception process using such authentication (first authentication) can prevent "the nurse from making a mistake in selecting a patient on the management device 100."

[0039] Next, the patient S to be treated leaves the management device 100 and heads toward the weighing scale 200. The patient S to be treated brings the terminal device 400 closer to the reader / writer 204 of the weighing scale 200, and in sequence SQ5, the terminal device 400 transmits the patient ID of the patient S to the weighing scale 200 by short-range wireless communication. Upon receiving the patient ID from the terminal device 400, the weighing scale 200 transmits the patient ID to the management device 100 in sequence SQ6.

[0040] In sequence SQ7, the management device 100 performs personal authentication (patient authentication) of the treatment target patient S using the patient ID acquired from the terminal device 400 via the weighing scale 200. That is, the management device 100 performs a second authentication of the treatment target patient S. Furthermore, the management device 100 determines whether the dialysis patient identified by the first authentication (dialysis patient identification process) (first authentication result) is the same as the dialysis patient identified by the second authentication (second authentication result). Hereinafter, this determination process is also referred to as the "first determination process."

[0041] In this case as well, the management device 100 displays the authentication result on the display 102. More specifically, the management device 100 outputs the result of the first determination process to the outside. In this example, the management device 100 displays the result on the display 102.

[0042] This allows the nurse to visually confirm the authentication result. More specifically, the nurse can see that the patient S to be treated who has checked in will start measuring his / her weight on the weighing scale 200. Since authentication has been performed twice up to this point, the nurse can double-check the patient S to be treated. Note that the authentication method is the same as the sequence SQ2 described above, and will not be repeated here.

[0043] In sequence SQ8, the management device 100 transmits the authentication result by short-range wireless communication to the terminal device 400. In sequence SQ9, the terminal device 400 displays the received authentication result on the touch screen 402. This allows the treatment target patient S to confirm that he or she has been authenticated.

[0044] Based on the above-mentioned second authentication of the patient S to be treated, the weight of the patient S to be treated is registered in the management device 100. The weight is stored in the management device 100 in association with the patient ID of the patient S to be treated. The management device 100 calculates the amount of water removed from the patient S to be treated based on the difference between the known dry weight of the patient S to be treated and the measured weight. Specifically, the management device 100 sets the value of the amount of water removed (target amount of water removed) in the patient information Q (FIG. 11) of the patient S to be treated.

[0045] On the condition that the dialysis patient is the same in the first judgment process, in sequence SQ10, the management device 100 identifies the dialysis device 300 to be used by the patient S to be treated from among the multiple dialysis devices 301 to 309. In detail, the management device 100 assigns a dialysis device 300 to be used to each dialysis patient in advance. More specifically, the management device 100 stores the identification information of the dialysis device 300 (hereinafter, "dialysis device ID") and the patient ID in association with each other. Furthermore, the management device 100 also stores the dialysis device ID and the bed number in association with each other. The management device 100 identifies the dialysis device 300 that has been assigned in advance to the patient S to be treated based on the authentication result in sequence SQ7.

[0046] In sequence SQ11, the management device 100 transmits location information U of the bed 700 on which the identified dialysis device 300 is installed to the terminal device 400. In sequence SQ12, the terminal device 400 displays an image based on the location information U. In detail, the terminal device 400 displays an image showing the location of the bed used by the treatment target patient S on the touch screen 402 based on the location information U. With such a display, the treatment target patient S knows the location of the bed he or she uses, and can easily reach the bed.

[0047] In the following description, for the sake of convenience, it is assumed that the dialysis machine 302 of the second bed 702 is assigned to the patient S to be treated. In more detail, it is assumed that the dialysis machine ID of the dialysis machine 302 and the patient ID of the patient to be treated are stored in advance in association with each other.

[0048] Next, the patient S to be treated leaves the scale 200 and moves toward the second bed 702. When the patient S to be treated moves the terminal device 400 closer to the reader / writer 354 of the dialysis machine 302, the terminal device 400 transmits the patient ID of the patient S to the dialysis machine 302 by short-range wireless communication in sequence SQ13. Upon receiving the patient ID from the terminal device 400, the dialysis machine 302 transmits the patient ID and the dialysis machine ID (third identification information) of the dialysis machine 302 to the management device 100 in sequence SQ14.

[0049] In sequence SQ15, the management device 100 performs personal authentication of the treatment target patient S using the patient ID acquired from the terminal device 400 via the dialysis device 302. That is, the management device 100 performs a third authentication of the treatment target patient S. Furthermore, the management device 100 determines whether or not the dialysis patient identified by the patient ID associated with the dialysis device ID received from the dialysis device 302 is the same as the dialysis patient identified by the patient ID received from the dialysis device 302 (third authentication result). Hereinafter, this determination process is also referred to as the "second determination process."

[0050] In this case as well, the management device 100 displays the authentication result on the display 102. The management device 100 outputs the result of the above-mentioned determination process to the outside. In this example, the management device 100 displays the result on the display 102.

[0051] This allows the nurse to visually confirm the authentication result. In detail, the nurse can know whether the patient S to be treated who has been accepted has reached the assigned bed 702 or has gone to the wrong bed. Note that the authentication method is the same as the sequence SQ2 described above, so it will not be repeated here.

[0052] In sequence SQ16, the management device 100 transmits the authentication result by short-distance wireless communication to the terminal device 400. In sequence SQ17, the terminal device 400 displays the received authentication result on the touch screen 402. This allows the treatment target patient S to confirm whether or not he or she has arrived at the correct bed.

[0053] By displaying the position of the bed 700 as described above and authenticating the dialysis machine 300, even if the bed used is different each time or if there is a sudden bed change, it is possible to guide the patient S to the appropriate bed 700 and dialysis machine 300.

[0054] Provided that the dialysis patient is the same in the above-mentioned second judgment process, in sequence SQ18, the management device 100 transmits patient information Q of the dialysis patient (patient S to be treated) authenticated in sequence SQ15 to the dialysis device 302 assigned to the patient S to be treated.

[0055] 4, in sequence SQ19, the dialysis machine 302 starts dialysis based on the patient information Q (patient information of the treatment target patient S) received from the management device 100. In detail, the management device 100 automatically performs settings based on the patient information Q. After the nurse checks the settings based on the patient information on the display 352 or the like, the dialysis machine 302 is operated.

[0056] In sequence SQ20, the dialysis machine 302 periodically acquires vital signs of the treatment target patient S and the operating state of the dialysis machine 302. The vital signs and the operating state are acquired (measured) by various sensors (not shown).

[0057] In this example, the vital signs include blood pressure, pulse, heart rate, and body temperature. The operating state is a state measured using a timer, a sensor (not shown), etc. in the dialysis device 302, such as the elapsed time from the start of dialysis and the fluid pressure of the dialysis fluid.

[0058] When the vital signs and the operating state of the dialysis machine 302 are acquired, the dialysis machine 302 transmits vital information V indicating the vital signs and device information W indicating the operating state of the dialysis machine 302 to the management device 100. As shown in sequences SQ21, SQ24, and SQ27, the dialysis machine 302 transmits the latest vital information V and device information W to the management device 100 at a predetermined cycle Tc. Note that, without being limited to this, the management device 100 may acquire the latest vital information V and device information W from the dialysis machine 302 via the server device 900 by sending a predetermined request signal to the dialysis machine 302 at a predetermined cycle (for example, cycle Tc).

[0059] When the management device 100 receives the vital information V and the device information W from the dialysis device 302, it transmits the received vital information V and device information W to the terminal device 400 as shown in sequences SQ22, SQ25, and SQ28. Typically, the terminal device 400 acquires the vital information V and the device information W from the management device 100 via the server device 900 by sending a predetermined request signal to the management device 100 at a predetermined period (for example, period Tc).

[0060] In sequence SQ23, terminal device 400 displays vital information V and device information W on touch screen 402. In sequences SQ26 and SQ29, terminal device 400 updates the display of vital information V and device information W with the latest vital information V and latest device information W.

[0061] According to such a system configuration, the patient S to be treated, who is a user of the terminal device 400, can know his / her vital signs by visually recognizing the display on the touch screen 402 of the terminal device 400. Furthermore, the patient to be treated can also know the operation information of the dialysis device 302.

[0062] <D. User Interface and Its Utilization> (d1. Management Device 100) FIG. 5 is a diagram for explaining an image displayed on the management device 100 after the sequence SQ2 in FIG. 3. As shown in FIG. 5, the management device 100 displays an image G11 on the display 102. The image G11 includes the authentication result, the name of the authenticated dialysis patient (patient S to be treated), and the bed number of the dialysis device 300 assigned to the dialysis patient. The nurse can confirm this information by the management device 100. The nurse can convey the number of the current bed to the patient S to be treated through the counter 800.

[0063] FIG. 6 is a diagram for explaining an image displayed on the management device 100 after the authentication by the dialysis device 302 by the patient S to be treated is completed. As shown in FIG. 6, the management device 100 displays an image G12 on the display 102 by a predetermined user operation.

[0064] The image G12 includes the name of the dialysis patient authenticated in the first authentication process, the result of the first determination process using the reader / writer 204 of the weighing scale 200, and the result of the second determination process using the reader / writer 354 of the dialysis device 300. In this example, "Nipro Tarou" at the top corresponds to the patient S to be treated described above.

[0065] By checking image G12, the nurse can prevent the dialysis patient from receiving treatment using the wrong dialysis machine 300. Furthermore, by checking the display in the weight scale column, the nurse can perform a double check of the treatment target patient S, as described above. The nurse can also determine whether the dialysis patient has reached the designated bed 700.

[0066] (d2. Terminal device 400) Fig. 7 is a diagram for explaining an image displayed on the touch screen 402 of the terminal device 400 by sequence SQ12 in Fig. 3. As shown in Fig. 7, the terminal device 400 displays an image G21 on the touch screen 402.

[0067] Image G21 shows a schematic diagram of the dialysis room 20. Image G21 shows the positions of a plurality of beds 700, the position of the counter 800, and the position of the weight scale 200. Image G21 shows the bed 702 (bed No. 2) of the dialysis device 302 assigned to the treatment target patient S in a manner different from the other beds.

[0068] By visually checking such image G21, the patient S to be treated can easily confirm the position of the bed to which he or she is heading. In particular, since the patient S to be treated moves while carrying the terminal device 400, the patient S to be treated can instantly confirm the position of the bed to which he or she is heading.

[0069] Fig. 8 is a diagram for explaining images displayed on the touch screen 402 of the terminal device 400 by sequences SQ23, SQ26, SQ29, etc. in Fig. 4. Fig. 9 is a diagram showing a dialysis patient undergoing dialysis.

[0070] As shown in FIG. 8, the terminal device 400 displays an image G22 on the touch screen 402. The image G22 includes the name of the dialysis patient, the current (latest) vital information V, and the current device information W. Therefore, as shown in FIG. 9, a dialysis patient (treatment target patient S) can confirm his or her own vital information V and device information W while lying in the bed 702 by the terminal device 400.

[0071] For this reason, when the dialysis patient confirms his or her own vital information V and device information W, it is no longer necessary to turn the display 352 of the dialysis device 300 towards himself or herself. Since the orientation of the display 352 is no longer changed by the dialysis patient in this way, the nurse can confirm the vital information V and device information W of the dialysis patient during dialysis without restoring the orientation of the display 352.

[0072] <E. Hardware Configuration, etc.> Hereinafter, the hardware configurations, etc. of the management device 100, the terminal device 400, the weighing scale 200, and each dialysis device 300 will be described. Furthermore, authentication by short-range wireless communication will also be described.

[0073] (e1. Management Device 100 and Terminal Device 400) FIG. 10 is a diagram for explaining the hardware configuration, etc. of the management device 100 and the terminal device 400. As shown in FIG. 10, in addition to the display 102, the input device 103, and the reader / writer 104 described above, the management device 100 includes a control device 111, a memory 112, and a communication interface 113. The control device 111, the memory 112, and the communication interface 113 are included in the main body 101 (FIG. 1) described above.

[0074] The memory 112 pre-stores an operating system, various programs, a patient information database P (FIG. 11), and bed allocation information R (FIG. 12). The patient information database P includes multiple pieces of patient information Q. One piece of patient information Q is information for one person. In this way, the patient information database P includes information Q for multiple patients. The communication interface 113 is an interface through which the management device 100 communicates via the network NW.

[0075] The control device 111 includes an authentication unit 119. The control device 111 is connected to the memory 112, the display 102, the input device 103, the reader / writer 104, and the communication interface 113. The control device 111 controls the overall operation of the management device 100. The control device 111 is typically configured by a processor. The authentication unit 119 is a functional block that is realized by the processor executing an operating system and a program stored in the memory 112.

[0076] The terminal device 400 includes, in addition to the above-mentioned touch screen 402, a control device 411, a memory 412, a communication interface 413, and a contactless integrated circuit card 414. The touch screen 402 includes a display 421 and a touch panel 422. The touch panel 422 is disposed (superimposed) on the display 421.

[0077] The memory 412 stores in advance an operating system, various programs including application programs downloaded from the server device 900, and a patient ID. The communication interface 113 is an interface for the management device 100 to communicate via the network NW. The terminal device 400 downloads application programs from the server device 900 via the communication interface 113.

[0078] The control device 411 is connected to the memory 412, the touch screen 402, the communication interface 413, and the contactless integrated circuit card 414. The control device 411 controls the overall operation of the terminal device 400. The control device 411 is typically configured by a processor.

[0079] The terminal device 400 can become a device constituting the dialysis system 1 by the processor executing the above-mentioned application program. That is, the terminal device 400 can participate in the dialysis system 1. In order to participate in the dialysis system 1, a dialysis patient needs to input a predetermined ID (e.g., a patient ID) and a password. The terminal device 400 can display, for example, images G21 and G22 shown in Figs. 7 and 8 on the display 421 by the application program.

[0080] When a dialysis patient brings the terminal device 400 close to the reader / writer 104 of the management device 100, the contactless integrated circuit card 414 of the terminal device 400 and the reader / writer 104 of the management device 100 perform short-range wireless communication. The contactless integrated circuit card 414 is read by the reader / writer 104 of the management device 100. As a result, the patient ID stored in the memory 412 of the terminal device 400 is transmitted to the management device 100.

[0081] The management device 100 performs personal authentication based on the received patient ID and the patient information database P stored in the memory 112 (first authentication, sequence SQ2 in FIG. 3). Specifically, the management device 100 selects a patient ID that matches the received patient ID from among multiple patient IDs included in the patient information database P. Next, the management device 100 identifies (authenticates) a dialysis patient having the selected patient ID from among the multiple dialysis patients.

[0082] Fig. 11 is a diagram for explaining a schematic configuration of the patient information database P shown in Fig. 10. As shown in Fig. 11, the patient information database P has a plurality of pieces of patient information Q. As described above, the patient information Q is information about one dialysis patient.

[0083] Each patient information Q includes information such as "patient ID," "name," "date of birth," "age," "gender," "blood type," "dialyzer type," "purification method," "dialysis date," "target dialysis (treatment) time," "dialysis fluid," "dry weight," "blood flow rate," "coagulant," "CTR (cardiothoracic ratio)," "medications used," "puncture site," "previous weight," "measured weight," "target water removal volume," "water removal rate," "dialysis fluid pump flow rate," "target accumulated volume of dialysis fluid," "substitution fluid pump flow rate," "target accumulated volume of substitution fluid," and "drainage pump flow rate."

[0084] Fig. 12 is a diagram for explaining the schematic configuration of the bed allocation information R shown in Fig. 10. As shown in Fig. 12, in the bed allocation information R, for each bed number, the dialysis machine ID and the name and patient ID of the patient scheduled to receive dialysis on each date are associated. For example, on July 1, the bed allocation information R indicates that a dialysis patient "Nipro Taro" with a patient ID "H7844" will receive dialysis in the second bed 702 using a dialysis machine 302 with a dialysis machine ID "T005". The bed allocation information R can also be said to be allocation information of the dialysis machine 300.

[0085] (e2. Scale 200) Fig. 13 is a diagram for explaining the hardware configuration of weighing scale 200. As shown in Fig. 13, weighing scale 200 includes control device 211, memory 212, and communication interface 213 in addition to display 202 and reader / writer 204 described above. Control device 211, memory 212, and communication interface 213 are included in main body 201 described above.

[0086] The control device 211 is connected to the memory 212, the display 202, the reader / writer 204, and the communication interface 213. The control device 211 controls the overall operation of the weight scale 200. The control device 211 is typically configured by a processor.

[0087] When a dialysis patient brings the terminal device 400 close to the reader / writer 204 of the weighing scale 200, the non-contact type integrated circuit card 414 of the terminal device 400 and the reader / writer 204 of the weighing scale 200 perform short-range wireless communication. The non-contact type integrated circuit card 414 is read by the reader / writer 204 of the weighing scale 200. As a result, the patient ID stored in the memory 412 of the terminal device 400 is transmitted to the weighing scale 200. The weighing scale 200 transmits the patient ID received from the terminal device 400 to the management device 100. In other words, the weighing scale 200 transfers the patient ID.

[0088] Furthermore, when the weight of the dialysis patient is measured by the weight scale 200, the measured weight (measurement result) is transmitted to the management device 100. The management device 100 manages the received patient ID and weight in association with each other.

[0089] After measuring the weight, the weighing scale 200 may transmit the patient ID in association with the weight to the management device 100. In other words, the patient ID is not limited to be transmitted before the weight measurement, but may be transmitted after the weight measurement.

[0090] The management device 100 performs personal authentication based on the received patient ID and the patient information database P stored in the memory 112 (second authentication, sequence SQ10 in FIG. 3). Specifically, the management device 100 selects a patient ID that matches the received patient ID from among multiple patient IDs included in the patient information database P. Next, the management device 100 identifies (authenticates) a dialysis patient having the selected patient ID from among the multiple dialysis patients. Thereafter, the management device 100 performs the first determination process described above.

[0091] (e3. Dialysis machine 300) 14 is a diagram for explaining the hardware configuration of the dialysis machine 302. Note that the other dialysis machines 300 (301, etc.) other than the dialysis machine 302 have the same hardware configuration as the dialysis machine 302, and therefore the description of the hardware configuration will not be repeated.

[0092] As shown in FIG. 14, in addition to the display 352 and the reader / writer 354 described above, the dialysis device 300 includes a control device 371, a memory 372, and a communication interface 373. The control device 371, the memory 372, and the communication interface 373 are included in the main body 351 described above.

[0093] The control device 371 is connected to the memory 372, the display 352, the reader / writer 354, and the communication interface 373. The control device 371 controls the overall operation of the dialysis device 302. The control device 371 is typically composed of a processor.

[0094] When a dialysis patient brings the terminal device 400 close to the reader / writer 354 of the dialysis device 302, the non-contact integrated circuit card 414 of the terminal device 400 and the reader / writer 354 of the dialysis device 302 perform short-range wireless communication. The non-contact integrated circuit card 414 is read by the reader / writer 354 of the dialysis device 302. As a result, the patient ID stored in the memory 412 of the terminal device 400 is transmitted to the dialysis device 302. The dialysis device 302 transmits the patient ID received from the terminal device 400 to the management device 100. That is, the dialysis device 302 transfers the patient ID.

[0095] The management device 100 performs personal authentication based on the received patient ID and the patient information database P stored in the memory 112 (third authentication, sequence SQ15 in FIG. 3). Specifically, the management device 100 selects a patient ID that matches the received patient ID from among the plurality of patient IDs included in the patient information database P. Next, the management device 100 identifies (authenticates) the dialysis patient having the selected patient ID from among the plurality of dialysis patients. Thereafter, the management device 100 performs the second determination process described above.

[0096] <F. Parentheses> The dialysis system 1 is as follows when enclosed in parentheses. Hereinafter, for convenience, the first determination process and the second determination process described above are referred to as the "first determination process" and the "second determination process", respectively.

[0097] (1) When the management device 100 acquires a patient ID (second identification information) from the portable terminal device 400 based on the approach of the management device 100, the management device 100 executes a first selection process to select a patient ID (first identification information) that matches the patient ID from among multiple patient IDs (first identification information). The management device 100 further executes a first identification process to identify a dialysis patient having the selected patient ID from among multiple dialysis patients. The management device 100 transmits patient information Q of the identified dialysis patient to the dialysis device 300 (designated dialysis device 300).

[0098] When dialysis of the identified dialysis patient is started based on the patient information Q, the dialysis machine 300 measures the vital signs of the dialysis patient during dialysis and transmits vital information V indicating the vital signs to the management device 100. The management device 100 transmits the vital information V received from the dialysis machine 300 to the terminal device 400. The terminal device 400 displays the vital information V received from the management device 100 on the display 421.

[0099] According to the above configuration, the management device 100 acquires a patient ID from the terminal device 400, and thus the management device 100 can identify a dialysis patient who is about to undergo dialysis. Furthermore, the terminal device 400 displays vital information V of the owner of the terminal device 400 (the dialysis patient). As a result, as shown in FIG. 9, a dialysis patient undergoing dialysis can check his / her own vital information V while lying in bed using the terminal device 400. Therefore, when checking his / her own vital information V, the dialysis patient does not need to turn the display 352 of the dialysis device 300 toward himself / herself. Therefore, a nurse can check the vital information V of a dialysis patient undergoing dialysis without returning the orientation of the display 352 to its original position.

[0100] As described above, according to the dialysis system 1, the portable terminal device 400 can be used to improve convenience for dialysis patients and medical staff.

[0101] (2) The dialysis machine 300 acquires the operating status of the dialysis machine 300, and further transmits the device information W indicating the operating status to the management device 100. The management device 100 transmits the device information W received from the dialysis machine 300 to the terminal device 400. The terminal device 400 displays the device information W received from the management device 100 on the display 421.

[0102] According to the above configuration, the terminal device 400 further displays the device information W of the dialysis device 300 on which the owner of the terminal device 400 is undergoing dialysis. As a result, as shown in Fig. 9, a dialysis patient undergoing dialysis can check his / her own device information W on the terminal device 400 while lying in bed. (3) When the weighing scale 200 acquires a patient ID (second identification information) from the terminal device 400 based on the approach of the terminal device 400 to the weighing scale 200, it transmits the patient ID to the management device 100. When the management device 100 acquires the patient ID from the weighing scale 200, it executes a second selection process to select a patient ID (first identification information) that matches the patient ID acquired from the weighing scale 200 from among multiple patient IDs (first identification information).

[0103] The management device 100 further executes a second identification process to identify a dialysis patient having a patient ID selected by the second selection process from among a plurality of dialysis patients. The management device 100 executes a first determination process to determine whether or not the dialysis patient identified by the first identification process described above is the same as the dialysis patient identified by the second identification process. The management device 100 outputs the result of the first determination process to the outside.

[0104] According to the above configuration, the nurse can determine whether the dialysis patient identified by the first identification process is the same as the dialysis patient identified by the second identification process based on the external output (typically, the display on the display 102). That is, the nurse can determine whether the dialysis patient who owns the terminal device 400 has been authenticated consecutively.

[0105] (4) Each dialysis machine 300 can acquire a patient ID from the terminal device 400. The management device 100 stores a dialysis machine ID set individually for each of the multiple dialysis machines 300. In the management device 100, the patient ID (first identification information) of the dialysis patient identified by the first identification process is previously associated with one of the multiple dialysis machine IDs. When each dialysis machine 300 acquires a patient ID (second identification information) from the terminal device 400 based on the terminal device 400 approaching the dialysis machine 300, the dialysis machine 300 is configured to transmit the patient ID and the dialysis machine ID of the dialysis machine 300 to the management device 100.

[0106] The management device 100 further executes a second determination process to determine whether or not a dialysis patient identified by a patient ID (first identification information) associated with the dialysis device ID received from the dialysis device 300 is the same as a dialysis patient identified by a patient ID (second identification information) received from the dialysis device 300. The management device 100 outputs the result of the second determination process to the outside.

[0107] According to the above configuration, a nurse can determine whether or not a dialysis patient has reached the assigned dialysis machine 300 based on an external output (typically, a display on the display 102).

[0108] (5) Each dialysis machine 300 is installed at the bedside of a different bed 700. The management device 100 pre-stores the position information of the bed 700 used by the dialysis patient identified by the above-mentioned first identification process. When the management device 100 identifies a dialysis patient by the above-mentioned first identification process, it notifies the terminal device 400 of the position information U of the bed 700 used by the identified dialysis patient. When the terminal device 400 receives the position information U, it displays an image based on the position information U (for example, image G21 in FIG. 7 ) on the display 421.

[0109] According to the above configuration, the dialysis patient can easily find his / her assigned bed 700 by referring to the image.

[0110] (6) The management device 100 displays an image (for example, image G21 in FIG. 6) including the name of the dialysis patient identified by the above first specific process, the result of the above first determination process, and the result of the above second determination process on the display 102. According to the above configuration, the nurse can confirm whether the dialysis patient has measured their weight and whether they have reached the bed 700 assigned to the dialysis patient.

[0111] (7) The dialysis system may be configured such that the management device 100, each dialysis device 300, and the terminal device 400 communicate with each other without passing through the network NW and the server device 900.

[0112] <G. Modification Example> The following modification examples can be combined as appropriate.

[0113] (g1. First Modification Example) In the above, the terminal device 400 performs short-range wireless communication with the management device 100, the weighing scale 200, and each dialysis device 300, and the management device 100 performs three authentications. In this modification example, a configuration using a two-dimensional code such as a QR code (registered trademark) instead of short-range wireless communication will be described.

[0114] FIG. 15 is a diagram showing a modification example of the management device 100. As shown in FIG. 15, the management device 100A includes a camera 109 instead of the reader / writer 104. The terminal device 400 stores a two-dimensional code indicating the patient ID. The dialysis patient causes the two-dimensional code displayed on the display 421 of the terminal device 400 to be read by the camera 109 of the management device 100A. The first authentication may be performed in such a manner.

[0115] Similarly, the second authentication and the third authentication may also be performed using a camera and a two-dimensional code. By using a two-dimensional code, the reader / writers 104, 204, 354 become unnecessary, and it is not necessary to mount the non-contact integrated circuit card 414 on the terminal device 400.

[0116] (g2. Second modified example) The dialysis patient can take pictures of his / her meals and the state of the shunt during dialysis using the terminal device 400, and store the pictures in the terminal device 400. The dialysis patient can also transmit the images obtained by the image capture to the management device 100, etc.

[0117] (g3. Third modified example) Various messages can also be sent from the management device 100 to the terminal device 400. For example, a nurse can use the management device 100 to send a message such as a request to change the dialysis start time to the terminal device 400. With this configuration, the dialysis patient can easily check messages from the hospital.

[0118] (g4. Fourth Variation) It is also possible to register dialysis conditions and contraindicated drugs in the terminal device 400. It is preferable that the information on dialysis conditions and contraindicated drugs in the terminal device 400 is updated every time dialysis is completed. By storing such information in the terminal device 400, even if the hospital where the patient is currently receiving treatment is affected by a disaster, the patient can receive dialysis treatment promptly at another hospital.

[0119] (g5. Fifth Variation) In the above, an example was given of a configuration in which the management device 100 manages master data such as a patient information database P containing each patient's information Q, bed allocation information R, etc., and performs patient authentication three times, but this is not limited to this.

[0120] The management device 100 may simply function as a client terminal of the server device 900. For example, the management device 100 may entrust application execution processing, data storage, and the like to the server device 900, like a thin client.

[0121] In such a configuration, the server device 900 manages master data such as the patient information database P including each patient's information Q and the bed allocation information R, and performs the above-mentioned three patient authentications. Furthermore, the server device 900 transmits the patient information Q to each dialysis device 300 based on an instruction from the management device 100. The server device 900 stores the vital information V and device information W transmitted from each dialysis device 300 in a memory as master data.

[0122] In detail, the server device 900 performs various processes that were previously performed by the management device 100, such as the first selection process, the second selection process, the first judgment process, the second judgment process, and the process for setting the value of the water removal amount, on behalf of the management device 100.

[0123] Regarding patient authentication, the server device 900 receives the patient ID acquired by the reader / writer 104 from the management device 100 and performs the first patient authentication described above. Similarly, the server device 900 receives the patient ID acquired by the reader / writer 204 from the weight scale 200 via the management device 100 and performs the second patient authentication described above. The server device 900 receives the patient ID acquired by the reader / writer 354 from the dialysis device 300 and performs the third patient authentication described above. The server device 900 transmits (externally outputs) each authentication result to the management device 100 and the terminal device 400.

[0124] In this example, the management device 100 and the terminal device 400 use browsers to display a Web page provided by the server device 900. For this reason, the server device 900 transmits to the management device 100 a Web page including image data for displaying various images such as images G11 and G12 shown in Figures 5 and 6, based on a request from the management device 100. The management device 100 transmits to the terminal device 400 a Web page including image data for displaying various images such as images G21 and G22 shown in Figures 7 and 8, based on a request from the terminal device 400.

[0125] In this example, the server device 900 generates the above-mentioned two-dimensional code and transmits it to the terminal device 400. The terminal device 400 receives the two-dimensional code from the server device 900 and stores it in the memory 403. The terminal device 400 displays the two-dimensional code on the display 421 based on the operation of the dialysis patient.

[0126] It is also possible to store the various images described in the second modified example in the server device 900. The terminal device 400 may be configured to configure the dialysis system 1 so as to acquire the dialysis conditions and contraindicated drugs shown in the fourth modified example from the server device 900.

[0127] In this modified example, the server device 900 corresponds to the "information processing device" of the present invention, and the management device 100 corresponds to the "second terminal device" of the present invention.

[0128] Furthermore, functions may be appropriately shared between the management device 100 and the server device 900. In this case, a configuration (system) in which the management device 100 and the server device 900 are combined corresponds to the "information processing device" of the present invention.

[0129] (g6. Sixth Variation) The dialysis system 1 may not include the server device 900. The management device 100 may function as a server in the dialysis system 1. That is, the dialysis system 1 may be configured so that the management device 100 communicates with the terminal device 400 and each dialysis device 300 without going through the network NW (FIG. 1).

[0130] (g7. Seventh Variation) 1, the dialysis system 1 includes a hub 500, but the hub 500 is not necessarily required. For example, the dialysis system 1 may be configured so that the management device 100, the weighing scale 200, and each dialysis device 300 are each communicatively connected to the server device 900 via a dedicated wired or wireless router (not shown) and a network NW that are individually connected to each of the devices.

[0131] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present disclosure is defined by the scope of the claims, and it is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.
