Description

[Technical field]

[0001] The present disclosure relates to a drug solution administration system, a terminal device, and an information processing method. [Background technology]

[0002] Conventionally, medical information systems such as a medical solution administration system that administers a medical solution to a patient by injection are known. For example, Japanese Patent Application Laid-Open No. 2006-72828 (Patent Document 1) discloses a medical information system including a fixed terminal device, a plurality of portable terminal devices, and a medical information server.

[0003] In the medical information system of Patent Document 1, a doctor inputs instructions (orders) including diagnosis and treatment for a patient into a fixed terminal device. A portable terminal device is connected to the fixed terminal device via a network, and notifies medical personnel in a predetermined manner that the instructions have been received. A medical information server is connected to the fixed terminal device and the portable terminal device via a network. The medical information server sets the portable terminal device that is to receive the instructions. The medical information server notifies the set portable terminal device of the instructions.

[0004] The medical information server has a monitoring means, a detection means, and a transmission means. The monitoring means monitors the fixed terminal device to see whether the instruction content has been newly input or changed. The detection means detects the instruction content of the new input or change input by the fixed terminal device monitored by the monitoring means. The transmission means transmits the instruction content detected by the detection means to the portable terminal device that is set to receive it.

[0005] Thus, in the medical information system of Patent Document 1, a doctor can use a fixed terminal device to change an order (order information) stored in a medical information server. Specifically, the fixed terminal device acquires an order that the doctor wishes to change from the medical information server and displays the order. The doctor operates the fixed terminal device to change the order. The doctor further operates the fixed terminal device to send the changed order to the medical information server. The changed order is detected by the medical information server and is notified to a specific mobile terminal device by the medical information server. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2006-72828 A Summary of the Invention [Problem to be solved by the invention]

[0007] Liquid administration pumps, such as infusion pumps and syringe pumps, that operate based on order information are used in hospital rooms, operating rooms, etc. In particular, in operating rooms, in the case of an emergency, doctors may verbally instruct medical staff to change the order information (more specifically, prescription data such as flow rate included in the order information). In this case, the medical staff will directly operate the liquid administration pump to change the order information stored in the liquid administration pump.

[0008] In such cases, medical staff are required to record the changes to the prescription data. For this reason, medical staff, for example, write down the changes by hand and later record the changes in an information processing device such as a server. In this way, when changes to the order information are instructed verbally, it is time-consuming for medical staff.

[0009] The present disclosure provides a medicinal liquid administration system, a terminal device, and an information processing method that enable medical professionals such as nurses to eliminate the need to record changes made when they receive verbal instructions from a doctor to change order information.

[0016] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[0017] First, a case where the order information including the prescription order for an injection for a patient is not changed will be described with reference to Figures 1 to 8. Next, a case where the order information is changed using a smartphone (described later) will be described with reference to Figures 9 to 12. The operation of changing the order information is typically performed by a nurse or the like based on oral instructions from a doctor.

[0018] Fig. 1 is a diagram showing the configuration of a medical system including a medicinal liquid administration system. As shown in Fig. 1, the medical system 1 includes a medicinal liquid administration system 5, a server 10 that records electronic medical records, a pharmacy department server 20, and a monitoring terminal 60. The medicinal liquid administration system 5 includes a server 30, a smartphone 40 as an example of a terminal device, and an infusion pump 50 as an example of a medicinal liquid administration pump.

[0019] The terminal device is not limited to the smartphone 40, but may be a portable device (mobile terminal device) such as a tablet terminal. The liquid administration pump is not limited to the infusion pump 50, but may be another pump such as a syringe pump. In this example, the monitoring terminal 60 is a PC (Personal Computer).

[0020] The smartphone 40 can also function as a terminal for monitoring the condition. Although only one infusion pump 50 is shown in Fig. 1, the liquid administration system 5 may include a plurality of liquid administration pumps.

[0021] The server 30 is communicatively connected to the servers 10, 20, and the monitoring terminal 60. Typically, the server 30 is connected to the servers 10, 20, and the monitoring terminal 60 by wires. The server 10 is communicatively connected to the server 20. Typically, the server 10 is connected to the server 20 by wires. Note that the server 30 may be communicatively connected to the monitoring terminal 60 wirelessly.

[0022] The server 30 is configured to be able to communicate with the smartphone 40 and the infusion pump 50. Typically, the server 30 can establish communication between the smartphone 40 and the infusion pump 50 via a wireless local area network (LAN).

[0023] The smartphone 40 communicates with the infusion pump 50. The smartphone 40 communicates wirelessly with the infusion pump. The smartphone 40 communicates with the infusion pump 50 via near field communication (NFC). In this example, the smartphone 40 communicates with the infusion pump 50 via Felica (registered trademark), which is a Type-F of NFC.

[0024] The smartphone 40 has a built-in reader / writer for Felica. The reader / writer has a control board and an antenna. The infusion pump 50 is equipped with Felica Link. The infusion pump 50 has a built-in contactless integrated circuit card for Felica (FeliCa Plug). The contactless integrated circuit card has an integrated circuit chip and an antenna. In the following, the contactless integrated circuit card is also referred to as a "contactless IC card."

[0025] In this example, by bringing the smartphone 40 operating as a reader / writer close to the infusion pump 50 operating as a tag, short-range wireless communication is performed between the smartphone 40 and the infusion pump 50. The reason why the smartphone 40, rather than the infusion pump 50, has a built-in reader / writer is because it is assumed that the smartphone 40 will also perform short-range wireless communication with a plurality of other pumps (not shown) in the same manner as with the infusion pump 50.

[0026] The server 10 prestores staff master data that stores personal information of each staff member (hereinafter referred to as "staff") belonging to the hospital, such as nurses, and patient master data that stores personal information of each patient. The staff master data and the patient master data are updated successively. The server 10 transmits the staff master data and the patient master data to the server 30. The server 10 typically transmits the staff master data and the patient master data to the server 30 in response to a request from the server 30 or based on the fact that the above-mentioned updates have been made.

[0027] When the server 10 acquires order information including a prescription order for an injection for a patient created by a doctor, the server records the received order information in the electronic medical record of the patient. The prescription order is created using a terminal (not shown) used by the doctor. During one treatment, the doctor creates a prescription order for each medicinal liquid. Therefore, when multiple medicinal liquids are administered to one patient, multiple pieces of order information are created and recorded in the electronic medical record.

[0028] The server 20 stores drug library data in advance. The server 20 transmits the drug library data to the server 30. When the drug library is updated in the server 20, the server 20 transmits update data for updating the drug library of the server 30 to the server 30. The server 20 may transmit the updated drug library data itself as the update data, or may transmit data of only the updated parts.

[0029] Server 20 acquires order information of a specified patient from server 10 based on an input operation by a pharmacist or the like. Server 20 transmits order information of a patient about to start treatment (hereinafter also referred to as a "target patient") to server 30. Servers 10 and 20 may handle multiple pieces of order information of the target patient as one list information. Staff in the pharmacy department judge whether the order information acquired by server 20 from server 10 is appropriate.

[0030] Fig. 2 is a diagram for explaining information stored in the server 30. As shown in Fig. 2, the server 30 includes a control unit 31 and a storage unit 32. The control unit 31 is a functional block realized by a processor executing an operating system and various programs stored in the storage unit 32. The storage unit 32 is specifically a memory. The memory includes a volatile memory and a non-volatile memory.

[0031] 1, the storage unit 32 of the server 30 stores staff master data, patient master data, the latest drug library data, and a plurality of pieces of order information #1, #2, ... #N. Each piece of order information #1, #2, ... #N includes information such as an order ID (Identification) for identifying the order information, a patient ID for identifying the patient, a drug name (medicinal solution name), a drug ID for identifying the drug, a set value for the flow rate of the medical solution (mL / h), and a set value for the dosage (mL). Furthermore, the order information includes information such as the scheduled date and time of administration, and the date and time of order creation.

[0032] In the example of Figure 2, each setting item of the order information, excluding the order ID and patient ID, and the information associated with the setting item (indicated as "***" in the figure) correspond to the prescription order. The information is a numerical value (specified value) in the case of the flow rate setting value, the dosage setting value, etc.

[0033] When multiple medicinal liquids are administered to the same patient at the same time, multiple order information (e.g., order information #1, #2) are prepared for the patient. In this case, the same patient ID is associated with different order IDs. Server 30 also stores past order information that has already been used as history.

[0034] The drug library data stores at least a flow rate (mL / h) threshold, a dosage (mL) threshold, and an administration rate (μg / kg / min) threshold in association with a drug name or drug ID. The dosage is also called a "scheduled amount."

[0035] The flow rate threshold includes an upper flow rate limit and a lower flow rate limit. The dosage threshold includes an upper dosage limit and a lower dosage limit. The administration rate threshold includes an upper administration rate limit and a lower administration rate limit. Note that the drug library data does not necessarily need to store all of the upper and lower limits for each drug solution.

[0036] Next, data transmission and reception within the drug solution administration system 5 shown in Fig. 1 will be described with reference to Fig. 1 and Fig. 3 to Fig. 6. Fig. 3 is a diagram showing the transition of screens on the smartphone 40.

[0037] With reference to Fig. 3, when the smartphone 40 starts a predetermined application program by an operation of a staff member (typically a nurse), the smartphone 40 displays a screen G41 on the touch screen 43 as shown in state (A) of Fig. 3. The screen G41 is a login screen. The screen G41 includes an image object 471. In this example, the application program has a function of reading one-dimensional codes (i.e., barcodes) and two-dimensional codes such as QR codes (registered trademark).

[0038] When the staff member selects image object 471 with the fingers of his / her hand 901, reading of the barcode using the camera is started. For example, the staff member uses the camera of smartphone 40 to capture an image of the barcode on a name tag worn by the staff member. The barcode has a staff ID written on it. In this manner, the staff ID is read by smartphone 40.

[0039] After the smartphone 40 reads the barcode, the staff member inputs a password into the smartphone 40. The staff member then selects a specific image object, which causes the smartphone 40 to transmit the staff member ID and password to the server 30. Through this process, the server 30 authenticates the staff member using the staff master data.

[0040] When the staff member is authenticated, the smartphone 40 displays a screen G42 on the touch screen 43 as shown in state (B). The screen G42 is a menu screen. The screen G42 includes image objects 472, 473, 474, and 475.

[0041] The image object 472 is an object for transitioning to a vital sign management screen. The image object 473 is an object for transitioning to an order transfer screen. The image object 474 is an object for transitioning to a monitoring device registration screen (i.e., monitoring device registration). The image object 475 is an object for transitioning to a screen showing a list of registered monitoring devices.

[0042] When the staff member selects image object 473 with his / her finger, the smartphone 40 displays screen G43 on the touch screen 43 as shown in state (C). Screen G43 and screens G44 to G46 described below are screens for transferring order information. Screen G43 includes image objects 476 and 477. In state (C), of image objects 476 and 477, only image object 476 is selectable. Image object 476 is an object for transitioning to a selection process (reading process) of a patient ID. Image object 477 is an object for transitioning to a selection process (reading process) of an order ID.

[0043] When the staff member selects the image object 476 with his / her finger, the smartphone 40 starts reading the barcode using the camera. The staff member captures an image of the barcode on the wristband attached to the wrist of the target patient with the camera of the smartphone 40. The patient ID is written on the barcode.

[0044] Fig. 4 is a diagram showing reading of a wristband by smartphone 40. As shown in Fig. 4, information such as the name, date of birth, blood type, and barcode 811 is printed on wristband 810 wrapped around wrist 951 of a subject patient. Staff reads barcode 811 using smartphone 40. Barcode 811 indicates (describes) the patient ID. In this manner, the patient ID is read by smartphone 40.

[0045] When the smartphone 40 reads the barcode 811, it transmits the patient ID to the server 30. Typically, the smartphone 40 transmits the patient ID to the server 30 via wireless LAN after confirmation input by a staff member (selection of an image object such as a send button). That is, the smartphone 40 transmits "(i) Patient ID" shown in FIG. 1 to the server 30.

[0046] When the smartphone 40 transmits the patient ID to the server 30, authentication is performed by the server 30 using the patient ID, and the smartphone 40 displays a screen G44 on the touch screen 43 as shown in state (D) of FIG. 3. The screen G44 includes an image object 478 and an image object 477.

[0047] The image object 478 indicates the patient ID obtained by reading the barcode 811. Note that the patient ID can be reset by selecting a reset button 4781 in the object 478.

[0048] When the staff member selects the image object 477 with his / her finger, the smartphone 40 resumes reading the barcode using the camera. The staff member captures an image of the barcode printed on the drug label of the target patient with the camera of the smartphone 40. The order ID is written in the barcode.

[0049] Fig. 5 is a diagram showing reading of a medicine label by smartphone 40. As shown in Fig. 5, information such as a patient ID, name, age, and barcode 821 is printed on a medicine label 820 of a target patient. A staff member reads barcode 821 using smartphone 40. An order ID is expressed (written) on barcode 821. In this manner, the order ID is read by smartphone 40.

[0050] When the smartphone 40 reads the barcode 821, it transmits the order ID to the server 30. Typically, the smartphone 40 transmits the order ID to the server 30 via wireless LAN after confirmation input by the staff member (selection of an image object such as a send button). That is, the smartphone 40 transmits "(ii) Order ID" shown in FIG. 1 to the server 30.

[0051] When the server 30 acquires the patient ID and the order ID from the smartphone 40, the server 30 executes the following process. The server 30 extracts order information including an order ID that matches the order ID sent from the smartphone 40 from among the multiple order information #1, #2, ..., #3 stored in the storage unit 32 (FIG. 2). That is, the server 30 extracts order information including an order ID that matches the order ID obtained by reading the barcode 821 of the medicine label 820 by the smartphone 40 from among the multiple order information #1, #2, ..., #3. Note that since there are no duplicate order IDs, the server 30 extracts one order information.

[0052] Next, the server 30 determines whether or not the patient ID (see FIG. 2) included in the extracted order information matches the patient ID sent from the smartphone 40. In other words, the server 30 determines whether or not the patient ID included in the extracted order information matches the patient ID obtained by reading the barcode 811 of the wristband 810 by the smartphone 40.

[0053] The server 30 transmits the extracted order information to the smartphone 40 on the condition that it is determined that the patient IDs match. That is, the server 30 transmits "(iii) order information" shown in Fig. 1 to the smartphone 40. Specifically, the server 30 transmits the extracted order information to the smartphone 40 by using communication via wireless LAN.

[0054] If the server 30 determines that the patient IDs do not match, it does not transmit the extracted order information to the smartphone 40. In this case, typically, the server 30 transmits information indicating an error or a warning to the smartphone 40.

[0055] When the smartphone 40 acquires (receives) the order information from the server 30, as shown in state (E) of FIG. 3, the smartphone 40 displays a screen G45 on the touch screen 43. The screen G45 includes an image object 478, an image object 480, and an image object 481.

[0056] Image object 480 shows the order information (excluding the patient ID) obtained from server 30. Staff can confirm the prescription order for injections for the target patient by visually checking the order information included in image object 480. Note that the order information can be reset (changed) by selecting a reset button 4801 in image object 480.

[0057] The image object 481 is an object for accepting the start of order transfer. When the staff member selects the image object 481 with his / her finger, the smartphone 40 switches the screen displayed on the touch screen 43 from screen G45 to screen G46 as shown in state (F) of FIG. 3, and prepares for short-range wireless communication with the infusion pump 50.

[0058] The screen G46 includes an image object 478, an image object 480, and an image object 482. The image object 482 includes a guidance display that prompts the staff to bring the smartphone 40 closer to the infusion pump 50. The image object 482 further includes a cancel button 4821 for canceling the transfer of the order information to the infusion pump 50. When the staff selects the cancel button 4821, the smartphone 40 switches the screen from the screen G46 to the screen G45, for example.

[0059] When the staff brings the smartphone 40 close to the infusion pump 50, short-range wireless communication is established between the smartphone 40 and the infusion pump 50. In more detail, when the staff holds the smartphone 40 over a FeliCa mark 590 (see FIG. 6 ) printed on the surface of the infusion pump 50, short-range wireless communication is established between the smartphone 40 and the infusion pump 50. When short-range wireless communication is established, the smartphone 40 transmits order information to the infusion pump 50. That is, the smartphone 40 transfers the order information acquired from the server 30 to the infusion pump 50.

[0060] The infusion pump 50 stores the order information transmitted from the smartphone 40 in the storage unit 52 (FIG. 7). The storage unit 52 corresponds to the "memory" of the present invention. The storage unit 52 includes a volatile memory and a non-volatile memory. In this example, the infusion pump 50 stores the order information in the volatile memory. However, this is not limited thereto, and the infusion pump 50 may store the order information in the non-volatile memory.

[0061] Fig. 6 is a diagram showing the states of the smartphone 40 and the infusion pump 50 immediately after the transfer of the order information is completed. As shown in Fig. 6, the smartphone 40 switches the screen of the touch screen 43 from screen G46 to screen G47. Screen G47 includes an image object 483 and an image object 484.

[0062] The image object 483 indicates that the transfer of the order information has been completed. The image object 483 further includes a notification urging the staff member to press a setting completion button represented as an image object 484 and to press a start button 591 of the infusion pump 50 after pressing the setting completion button. When the staff member presses the setting completion button, for example, the smartphone 40 switches the screen from the screen G47 to the screen G42 (FIG. 3).

[0063] In addition to the start button 591, the infusion pump 50 is equipped with a power button 592, a menu button 593, and a stop / mute button 594. The infusion pump 50 is further equipped with a display 55. When the infusion pump 50 receives order information from the smartphone 40, the infusion pump 50 displays a screen G51 on the display 55. The screen G51 includes information that the operation of the infusion pump 50 is stopped. The screen G51 further includes information on the drug name, planned amount, and flow rate included in the order information. The screen G51 includes an item for the accumulated amount.

[0064] When the staff member presses the start button 591 of the infusion pump 50 while the screen G51 is displayed on the display 55 of the infusion pump 50, administration of the medicinal fluid by the infusion pump 50 is started. When the staff member presses the power button 592 to turn off the power of the infusion pump 50, the order information stored in the memory unit 52 (i.e., memory) of the infusion pump 50 is erased.

[0065] 7 is a block diagram of each device constituting the medicinal liquid administration system 5. As described above, the medicinal liquid administration system 5 is composed of the server 30, the smartphone 40, and the infusion pump 50.

The control unit 41 controls the overall operation of the smartphone 40. For example, the control unit 41 controls the screen display on the touch screen 43. The storage unit 42 stores an operating system and various application programs including the above-mentioned predetermined application programs. These are executed by the control unit 41 (more specifically, a processor).

[0067] The touch screen 43 includes a display 431 and a touch panel 432. The touch panel 432 is superimposed on the display 431. The scanner 44 includes a camera 441 and a data processing unit 442. The camera 441 includes an image sensor. The data processing unit 442 performs various types of data processing. In this example, the data processing unit 442 functions as a barcode reader. The scanner 44 sends a patient ID and an order ID to the control unit 41.

[0068] The Wi-Fi communication unit 45 is a communication interface that performs wireless communication via Wi-Fi. As shown as “(i) Patient ID” and “(ii) Order ID” in FIG. 1, the smartphone 40 transmits a patient ID and an order ID to the server 30 using the Wi-Fi communication unit 45.

[0069] The reader / writer 46 includes a transmitting unit 461 and a receiving unit 462. As described above, the smartphone 40 performs short-range wireless communication with the infusion pump 50 using the reader / writer 46. The smartphone 40 transmits (transfers) the order information acquired from the server 30 to the infusion pump 50, as shown as "(iv) order information" in FIG. 1.

[0070] The server 30 includes a control unit 31, a storage unit 32, a wired communication unit 33, and a Wi-Fi communication unit 34. The control unit 31 controls the overall operation of the server 30. The storage unit 32 includes an operating system and various programs. These are executed by the control unit 31 (more specifically, a processor). The wired communication unit 33 is a communication interface for communicating with the servers 10 and 20 and the monitoring terminal 60.

[0071] When the server 30 receives the patient ID and the order ID from the smartphone 40, as described above, it extracts order information including an order ID that matches the received order ID from among the multiple order information #1, #2, ... #N.

[0072] The server 30 transmits the extracted order information to the smartphone 40 on the condition that the patient ID included in the extracted order information matches the patient ID received from the smartphone 40. Specifically, as shown as "(iii) Order Information" in FIG. 1, the server 30 transmits the order information to the smartphone 40 using the Wi-Fi communication unit 34. Upon receiving the order information from the server 30, the smartphone 40 transmits the order information to the infusion pump 50 ("(iv) Order Information" in FIG. 1). In this manner, the smartphone 40 transfers the order information acquired from the server 30 to the infusion pump 50.

[0073] The infusion pump 50 includes a control unit 51, a storage unit 52, an operation button 53, a Wi-Fi communication unit 54, a display 55, and a non-contact IC card 56. The control unit 51 controls the overall operation of the infusion pump 50. The storage unit 52 stores an operating system and various programs. These are executed by the control unit 51 (more specifically, a processor). The operation button 53 includes various buttons such as a start button 591, a power button 592, and a menu button 593, as shown in FIG. 7 and other figures.

[0074] The infusion pump 50 acquires the order information from the smartphone 40 using the non-contact IC card 56. This enables the infusion pump 50 to perform settings and operations based on the order information.

[0075] The infusion pump 50 communicates with the server 30 using the Wi-Fi communication unit 54. As shown in FIG. 1 as "(v) Operational Status Information," the infusion pump 50 transmits the operational status of the infusion pump 50 to the server 30 using the Wi-Fi communication unit 54. The monitoring terminal 60 can obtain information indicating the operational status from the server 30 and display the operational status on a display. This allows staff to monitor the operational status of the infusion pump 50 using the monitoring terminal 60.

[0076] The control unit 51 of the infusion pump 50 controls the screen display on the display 55. The control unit 51 accepts a selection operation of image objects 551, 552 shown in FIG. 7 by a staff member using the operation buttons 53. The control unit 51 controls writing of data to the storage unit 52 and reading of data. For example, the control unit 51 writes order information to the storage unit 52, overwrites the order information, and erases (deletes) the order information from the storage unit 52.

[0077] 8 is a sequence diagram for explaining the flow of data processing in medicinal solution administration system 5. As shown in FIG. 8, in sequence SQ1, smartphone 40 reads barcode 811 printed on wristband 810 of a target patient with scanner 44. In sequence SQ2, smartphone 40 transmits the patient ID, which is the result of reading barcode 811, to server 30.

[0078] In sequence SQ3, the smartphone 40 reads the barcode 821 printed on the medicine label 820 of the target patient with the scanner 44. In sequence SQ4, the smartphone 40 transmits the order ID, which is the reading result of the barcode 821, to the server 30.

[0079] In sequence SQ5, the server 30 extracts, from among a plurality of pre-stored pieces of order information, order information that includes the same order ID as the order ID received from the smartphone 40. In sequence SQ6, the server 30 extracts the patient ID included in the extracted order information. In sequence SQ7, the server 30 checks whether the patient ID received from the smartphone 40 matches the patient ID extracted from the order information.

[0080] If the two patient IDs match, in sequence SQ8, the server 30 transmits the order information extracted in sequence SQ5 to the smartphone 40. In sequence SQ9, the smartphone 40 accepts a transfer operation of the order information received from the server 30. Upon accepting the transfer operation, in sequence SQ10, the smartphone 40 transmits the order information to the infusion pump 50 by short-range wireless communication. The transfer operation refers to the selection of the image object 481 and holding the smartphone 40 over the infusion pump 50.

[0081] In sequence SQ11, when the start button 591 (FIG. 6) is pressed by the staff, the infusion pump 50 starts operation based on the received order information, thereby injecting the medicinal fluid from the infusion pump 50 to the patient.

[0082] Next, a process of changing the order information acquired from the server 30 by the smartphone 40 will be described with reference to Figs. 9 to 12. In this example, a case will be described in which a staff member receives an oral instruction to change the order information from a doctor while the infusion pump 50 is operating based on the order information. Such an oral instruction to change the order information is given, for example, when the patient's condition suddenly changes during surgery. The timing of the oral instruction to change the order is not limited to the above-mentioned situation, and may be given, for example, after the infusion pump 50 acquires the order information from the smartphone 40 and before the infusion pump 50 starts operating based on the order information.

[0083] Fig. 9 is a diagram for explaining the operation and data flow in the drug solution administration system 5. In detail, Fig. 9 is a diagram for explaining the operation and data flow after starting the process of transmitting operation status information to the server 30 ("(v) Operation status information" in Fig. 1). Fig. 10 is a diagram showing the transition of the screen of the smartphone 40.

[0084] With reference to FIG. 9, the staff member who has received verbal instructions from the doctor to change the order information operates the smartphone 40. Changing the order information means changing the values ​​of the setting items included in the prescription data (see FIG. 2). Changing the order information means, for example, changing the setting value of the flow rate. Hereinafter, the order information in which the prescription order has been changed is also referred to as "changed order information."

[0085] The staff member operates the smartphone 40 to display the screen G45 shown in state (A) of Fig. 10 on the touch screen 43 (more specifically, the display 431) of the smartphone 40. Note that state (A) of Fig. 10 is the same as state (E) of Fig. 3.

[0086] Next, the staff member selects a reset button 4801 included in screen G45. When the reset button 4801 is selected, the smartphone 40 transitions the screen displayed on the touch screen 43 from screen G45 to a screen (not shown) that accepts changes to the values ​​of each setting item (see FIG. 2) of the prescription order. On this screen, the smartphone 40 accepts a touch operation by the staff member to change the values ​​of the setting items.

[0087] In this way, the smartphone 40 accepts the operation shown as "(vi) Change operation of order information (change operation of prescription order)" in Fig. 9. Note that the change operation here is an operation to change the order information stored in the smartphone 40 (order information acquired from the server 30).

[0088] The smartphone 40 accepts an input for changing the order information by manual key operation (touch operation in this example). However, the present invention is not limited to this, and the smartphone 40 may accept an input for changing the order information by voice. In other words, the smartphone 40 may accept the input via a microphone (not shown).

[0089] When the staff member finishes inputting the value (specified value) of the setting item, the staff member selects a predetermined button (e.g., a confirm button) (not shown). Based on the staff member's selection of the button, the smartphone 40 confirms the change to the order information. Specifically, the smartphone 40 overwrites and updates the value of the setting item.

[0090] Furthermore, the smartphone 40 transitions the screen displayed on the display 431 to a screen G45' that accepts an operation to send order information, as shown in state (B) of Fig. 10. For example, when a staff member performs an operation to change the set value of the flow rate from "10.00 mL / h" to "12.50 mL / h", the value of the flow rate switches from "10.00 mL / h" to "12.50 mL / h", as shown on the screen G45'.

[0091] Thereafter, the staff member stops the operation of the infusion pump 50 by pressing the stop / mute button 594 (FIG. 6) of the infusion pump 50, as shown as "(vii) Stop" in FIG 9. Next, the staff member selects the image object 481 for accepting the start of order transfer, as shown in state (B) in FIG 10.

[0092] When the staff member selects image object 481 with his / her finger, the smartphone 40 switches the screen displayed on the touch screen 43 from screen G45' to screen G46', as shown in state (C) of Figure 10, and prepares for short-range wireless communication with the infusion pump 50.

[0093] 3, the screen G46' includes an image object 478, an image object 480, and an image object 482. When the staff member selects the cancel button 4821, the smartphone 40 switches the screen from the screen G46' to a screen G45', for example.

[0094] When the staff brings the smartphone 40 close to the infusion pump 50 again, short-range wireless communication is re-established between the smartphone 40 and the infusion pump 50. When the short-range wireless communication is established, the smartphone 40 transmits the changed order information to the infusion pump 50, as shown as "(viii) Changed order information" in Fig. 9. That is, the smartphone 40 transfers the order information, in which the prescription order included in the order information acquired from the server 30 has been changed, to the infusion pump 50.

[0095] The infusion pump 50 stores the changed order information transmitted from the smartphone 40 in the storage unit 52 (FIG. 7). Specifically, the infusion pump 50 overwrites the already stored order information with the changed order information. At this time, the infusion pump 50 inquires of the staff whether or not overwriting is necessary. Specifically, the infusion pump 50 displays an image object (not shown) that allows overwriting on the display 55. When the staff selects the image object, the infusion pump 50 overwrites the order information. As a result, the order information in the infusion pump 50 is updated with the changed order information.

[0096] As shown as "(ix) Notification of Changes" in FIG. 9, the smartphone 40 notifies the server 30 of the changes to the order information. In detail, the smartphone 40 notifies the server 30 of the changes to the prescription order. In this example, the smartphone 40 transmits the changed order information to the infusion pump 50, and then notifies the server 30 of the changes. At that time, the smartphone 40 notifies the server 30 of the order ID along with the changes. The smartphone 40 may also notify the server 30 of the patient ID along with the order ID.

[0097] After the changed order information is transmitted to the infusion pump 50, the staff member presses the start button 591 (FIG. 6) of the infusion pump 50. As a result, the infusion pump 50 resumes operation based on the changed order information, as shown as "(x) Resume" in FIG. 9. After resuming operation, the infusion pump 50 transmits the operation status of the infusion pump 50 to the server 30 using the Wi-Fi communication unit 54, as shown as "(xi) Operation Status Information" in FIG. 9. In this example, a series of operations including the selection of an image object to be allowed to be overwritten and the pressing of the start button 591 (FIG. 6) corresponds to the "predetermined operation" of the present disclosure.

[0098] The above-mentioned "notification of changes" will be specifically described below. In this example, the smartphone 40 notifies the server 30 of the changes to the prescription order by transmitting order information including the changed prescription order to the server 30. That is, the smartphone 40 notifies the server 30 of the changed order information itself. In this manner, the smartphone 40 transmits the changed order information to the infusion pump 50 and the server 30. With this configuration, the server 30 can obtain the same information as the changed order information transmitted to the infusion pump 50.

[0099] In this case, when the server 30 receives order information including the changed prescription order from the smartphone 40, the server 30 stores the order information including the changed prescription order in the memory unit 32 with a predetermined flag attached.

[0100] Without being limited to the above, the smartphone 40 may notify the server 30 of the change in the prescription order by transmitting to the server 30 the value (designated value) changed in the prescription order and information identifying the setting item to which the changed value is associated (specifically, the setting item name). For example, when the flow rate setting value is changed from "10.00 mL / h" to "12.50 mL / h" as described above, the smartphone 40 notifies the server 30 of the change in the prescription order by transmitting to the server 30 "12.50 mL / h" and the "flow rate setting value" (setting item name) in association with each other. In this way, the smartphone 40 may notify the server 30 of only the changed part of the prescription order (that the flow rate setting value has been changed to 12.50 mL / h).

[0101] As shown in Fig. 2, the server 30 stores a plurality of pieces of order information. Therefore, in order to enable the server 30 to know which piece of prescription data has been changed, the smartphone 40 notifies the server 30 of the order ID together with the setting item name and the changed value.

[0102] In this case, when the server 30 receives the setting item name and the changed value from the smartphone 40, the server 30 stores the setting item name and the changed value with a predetermined flag attached in the storage unit 32. More specifically, the server 30 stores the setting item name and the changed value with a predetermined flag attached in the storage unit 32 in association with the order ID received from the smartphone 40.

[0103] As described above, the server 30 stores the change contents with a flag attached in the storage unit 32. The server 30 transmits the flagged information (in this case, the change contents) at a predetermined timing to the server 10 (see FIG. 1) that records the electronic medical record. In this case, the server 10 updates the electronic medical record based on the information. This allows the changed prescription order to be stored in the electronic medical record.

[0104] The "predetermined timing" may be a timing managed by the server 30 (for example, a predetermined cycle), or may be a timing when a predetermined request signal is received from the server 10. The predetermined request signal is a signal that inquires about the presence or absence of changes in the order information, and if there are changes, the contents of the changes.

[0105] FIG. 11 is a block diagram for explaining the functional configuration of the smartphone 40. The hardware configuration shown in FIG. 11 is the same as the hardware configuration in FIG. 7. As shown in FIG. 11, the control unit 41 of the smartphone 40 has a change unit 411. The Wi-Fi communication unit 45 functions as an acquisition unit and a notification unit, which will be described later. The touch screen 43 functions as an input reception unit, which will be described later. In this manner, the smartphone 40 has the change unit 411, an acquisition unit, a notification unit, and an input reception unit. Furthermore, the smartphone 40 has a transmission unit 461.

[0106] The acquisition unit of the smartphone 40 acquires the order information from the server 30. The input reception unit accepts an input for changing the prescription order in the acquired order information. The change unit 411 changes the prescription order included in the order information acquired from the server 30 based on the input. The transmission unit 461 transmits the order information including the changed prescription order to the infusion pump 50. The notification unit notifies the server 30 of the change in the prescription order.

[0107] Fig. 12 is a sequence diagram for explaining the flow of data processing in the medicinal solution administration system 5. As shown in Fig. 12, in sequence SQ21, the smartphone 40 accepts an operation to change the order information. Following sequence SQ21, in sequence SQ22, the infusion pump 50 accepts a pressing operation of the stop / mute button 594.

[0108] Following sequence SQ22, in sequence SQ23, the smartphone 40 accepts a transfer operation of the order information. Specifically, the smartphone 40 accepts a selection operation of the image object 481 (state (B) in FIG. 10 ) and an operation of bringing the smartphone 40 close to the infusion pump 50 (holding the smartphone 40 over the infusion pump 50).

[0109] In sequence SQ24, the smartphone 40 transmits the changed order information to the infusion pump 50. In sequence SQ25, the smartphone 40 notifies the server 30 of the changes to the order information.

[0110] Following sequence SQ24, in sequence SQ26, the infusion pump 50 overwrites the existing order information with the changed order information. In sequence SQ28, when the start button 591 (FIG. 6) is pressed, the infusion pump 50 starts operation based on the changed order information. Following sequence SQ25, in sequence SQ27, the server 30 stores the changes notified from the smartphone 40.

[0111] In view of the above-described aspect of changing the order information, it can be said that the medicinal liquid administration system 5 and the smartphone 40 included in the medicinal liquid administration system 5 have at least the following configuration.

[0112] (1) The medicinal solution administration system includes a server 30, a smartphone 40 that communicates with the server 30, and an infusion pump 50 that communicates with the smartphone 40. The server 30 stores order information including a prescription order for an injection for a patient.

[0113] The smartphone 40 acquires order information from the server 30. When the smartphone 40 receives an input to change the prescription order after acquiring the order information, the smartphone 40 changes the prescription order included in the order information acquired from the server 30 based on the input. The smartphone 40 transmits the order information including the changed prescription order to the infusion pump 50. The smartphone 40 notifies the server 30 of the changes to the prescription order. The infusion pump 50 operates based on the changed prescription order. The server 30 stores the notified changes.

[0114] According to this configuration, when a staff member receives verbal instructions from a doctor to change the order information, the staff member can change the order information of the infusion pump 50 by operating the smartphone 40. Furthermore, the smartphone 40 can notify the server 30 of the changes to the prescription order. In this way, since the changes to the prescription order are notified to the server 30, the staff member does not need to take handwritten notes of the changes. Therefore, when a staff member receives verbal instructions from a doctor to change the order information, it is possible to omit the staff member's task of recording the changes.

[0115] For example, if the changes are written by hand, the notes may be illegible if there are typos. In such cases, accurate order information cannot be stored in the electronic medical record, etc. However, according to the medicinal liquid administration system 5, accurate order information can be stored at least in the server 30.

[0116] (2) As shown in sequences SQ24 and SQ25 in Fig. 12, the smartphone 40 notifies the server 30 of the changes to the prescription order on condition that the order information including the changed prescription order has been transmitted to the infusion pump 50. According to this configuration, the changes are not notified to the server 30 in advance when the changed order information has not yet been transmitted to the infusion pump 50. In this way, according to the medicinal solution administration system 5, it is possible to notify the server 30 of the changes to the changed order information that has already been transmitted to the infusion pump 50.

[0117] (3) As shown in Fig. 2, the order information further includes an order ID for identifying the order information. The smartphone 40 notifies the server 30 of the changes to the prescription order together with the order ID. With this configuration, the server 30 can determine, based on the order ID, which of the multiple pieces of order information (see Fig. 2) the notified changes relate to.

[0118] (4) The smartphone 40 notifies the server 30 of the changes to the prescription order by transmitting order information including the changed prescription order to the server 30. With this configuration, the server 30 can obtain the changed order information itself.

[0119] (5) As shown in Fig. 11, the server 30 has a storage unit 32 that stores the order information transmitted to the smartphone 40. When the server 30 receives the order information including the changed prescription order from the smartphone 40, the server 30 stores the order information including the changed prescription order in the storage unit 32 with a predetermined flag attached.

[0120] With this configuration, the server 30 can recognize that the order information acquired from the smartphone 40 is different from the multiple pieces of order information stored in advance (see FIG. 2) based on the presence or absence of the flag. Therefore, the server 30 can selectively transmit the order information acquired from the smartphone 40 to the server 10 that records the electronic medical record.

[0121] (6) As shown in FIG. 2, a prescription order includes a plurality of setting items. A designated value is associated with each setting item and stored. An input for changing a prescription order is an input for changing the designated value of one or more setting items among the plurality of setting items. The smartphone 40 notifies the server 30 of the change in the prescription order by transmitting to the server 30 the changed designated value and information identifying the setting item with which the changed designated value is associated (e.g., the name of the setting item).

[0122] According to this configuration, the server 30 obtains from the smartphone 40 the changed specified value and information identifying the setting item to which the changed specified value is associated, thereby eliminating the need to obtain the changed order information itself.

[0123] (7) As shown in Fig. 11, the server 30 has a storage unit 32 that stores the order information transmitted to the smartphone 40. When the server 30 receives the changed designated value and the information identifying the setting item from the smartphone 40, the server 30 stores the changed designated value and the information identifying the setting item in a state in which a predetermined flag is attached in the storage unit 32.

[0124] According to such a configuration, the server 30 can recognize that the information acquired from the smartphone 40 (i.e., the information identifying the changed designated value and the setting item) is different from the information stored in advance, based on the presence or absence of the flag. Therefore, the server 30 can selectively transmit the above information acquired from the smartphone 40 to the server 10 that records the electronic medical record.

[0125] (8) The smartphone 40 accepts input for changing the prescription order by voice or key operation.

[0126] (9) As shown in FIG. 11 , the smartphone 40 includes an acquisition unit that acquires order information including a prescription order for an injection for a patient from a server device, an input receiving unit that receives input to change the prescription order, a change unit 411 that changes the prescription order included in the order information acquired from the server 30 based on the input, a transmission unit 461 that transmits the order information including the changed prescription order to the infusion pump 50, and a notification unit that notifies the server 30 of the change in the prescription order.

[0127] According to this configuration, when a staff member receives verbal instructions from a doctor to change the order information, the staff member can operate the smartphone 40 to transmit the changed order information to the infusion pump 50. Furthermore, the smartphone 40 can notify the server 30 of the changes to the prescription order. In this way, since the changes to the prescription order are notified to the server 30, the staff member does not need to take handwritten notes of the changes. Therefore, when a staff member receives verbal instructions from a doctor to change the order information, it is possible to omit the staff member's task of recording the changes.

[0128] 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.
