Description

The present invention relates to an information processing method in a medical support system, and more specifically, information for incorporating patient vital data measured at a medical institution such as a hospital into a medical support system that handles electronic documents such as medical records and nursing records. Regarding the processing method.

In recent years, in medical institutions such as hospitals, measuring devices (for example, thermometers, pulse oximeters, sphygmomanometers, blood glucose meters, etc.) that measure vital signs of patients (for example, body temperature, pulse, blood pressure, blood glucose level, etc.) , A configuration has been proposed in which the measured vital sign data (vital data) is read by a non-contact IC card reader using short-range wireless communication technology (see Non-Patent Document 1).

This type of measuring device has a built-in IC chip (for example, NFC chip) that supports short-range wireless communication, and the measured vital data is stored in the memory area inside the IC chip, and the measuring device is stored in an IC card reader. By holding it over, short-range wireless communication is performed between the measuring device and the IC card reader, and the vital data stored in the IC chip can be read by the IC card reader.

Web page of product information about vital sign measuring equipment with communication function (https://www.terumo.co.jp/medical/equipment/me303.html)

However, such a conventional method has the following problems.
That is, in the conventional system, in order to read the vital data stored in the IC chip of the measuring device, a dedicated software for reading the data is installed on the computer for inputting the vital data, and a dedicated IC card for reading the data is installed. This is done by connecting a reader.

On the other hand, as for the software and IC card reader for reading data in this type of measuring device, different software and IC card reader are provided for each manufacturer of the measuring device.

Therefore, when a medical institution introduces a measuring device of a different manufacturer when introducing this type of measuring device, it is necessary to install software of all manufacturers on a computer (business terminal device) for medical support. IC card readers from all manufacturers also had to be connected. FIG. 5 shows vital data measured by a thermometer (manufactured by company A), a pulse oximeter (manufactured by company B), a weight scale (manufactured by company C), and a glucose meter (manufactured by company D) from different manufacturers for medical support. The connection state of the IC card reader when the computer is made to read is schematically shown.

Here, most of the work such as measuring the vital data of the patient and inputting the measurement result to the computer is performed in the hospital room. Therefore, a notebook-type or tablet-type computer that is easy to carry is preferably used as a computer for medical support for inputting vital data, but in the conventional method, a plurality of ICs are used in a computer that is premised on such carrying. While it is inconvenient to carry because the card reader is connected, when inputting data, it is necessary to accurately select the IC card reader corresponding to the measuring device, and it takes time and effort to input the data. There was a problem such as.

The present invention has been made in view of such problems, and an object of the present invention is information that can share an IC card reader connected to a business terminal device for inputting vital data in a medical support system. The purpose is to provide a processing method.

In order to achieve the above object, the inventors of the present application have conventionally used an IC card for user authentication of a business terminal device in addition to an IC card reader for inputting vital data in the business terminal device of the medical support system. I focused on having a reader. Then, the following information processing method was invented in order to realize the unification of the IC card reader connected to the business terminal device by making the IC card reader for user authentication also available for inputting vital data. I came to do it.

Reference information for device identification that uniquely identifies the measuring device that measures the patient's vital data is stored in advance in a predetermined storage area.
When data is input to the non-contact IC card reader, the input data is collated with the reference information for user authentication and the reference information for device identification, and as a result of the collation, the user authentication is performed. If the data matching the reference information is included, the user authentication process is executed by the authentication server, and if the data matching the reference information for device identification is included, the business terminal device is used. It is characterized by executing a reading process of vital data.

The information processing method in the medical support system according to claim 2 of the present invention is
A business terminal device for inputting patient vital data, an authentication server having reference information for user authentication of the business terminal device, and a non-contact IC card reader for inputting authentication elements of the business terminal device. An information processing method for using the non-contact IC card reader as an input device for vital data in a medical support system provided.
When the predetermined application is not started, the business terminal device accepts the data input to the non-contact IC card reader as the data for user authentication, and the predetermined application is started. When, the data input to the non-contact IC card reader is accepted as the vital data of the patient.

The information processing method in the medical support system according to claim 3 of the present invention is
The predetermined application is characterized in that it is an application for electronically documenting vital data.

According to the present invention, a non-contact IC card reader provided for user authentication of a business terminal device can be used as an IC card reader for reading vital data, so that an IC connected to the business terminal device can be used. The card reader can be unified.

In addition, since both user authentication and reading of vital data can be realized with a single IC card reader, the number of IC card readers connected to the business terminal device is reduced, and the business terminal device is excellent in portability and operability. Can be provided.

Be placed. The business terminal device 200 may be composed of a so-called desktop computer, but is preferably composed of a small computer such as a notebook computer or a tablet computer that is easy to carry.

Here, the business terminal device 200 can use the application of the nursing support system stored in the application server 100 by the client server system with the application server 100 described above. Therefore, the business terminal device 200 is adapted to receive user authentication by the authentication server 300 at at least one of the timings when the application is started and when the business terminal device 200 is started.

Along with this, in the present embodiment, the business terminal device 200 is provided with an IC card reader 201 for user authentication. The IC card reader 201 is inside the IC chip of a contactless IC card (not shown) given to a person who is authorized to operate the business terminal device 200 (or a person who has access to the nursing support system). It is a card reader for reading user authentication data (data for personal identification) D1 stored in, and is composed of a non-contact type card reader.

Specifically, the IC card reader 201 is composed of a non-contact IC card reader capable of transmitting and receiving data to and from an IC card by short-range wireless communication (NFC: Near Field Communication). In the illustrated example, the case where the IC card reader 201 is configured by a card reader of a type connected to the business terminal device 200 by wire is shown, but it is configured by the type of IC card reader built in the business terminal device 200. You may.

The authentication server 300 is a server computer that authenticates the user when the business terminal device 200 is started or when the application (in this embodiment, the application of the nursing support system) is started, and the application server 100 and the business are performed via the network N. Communication connection is made with the terminal device 200 and the like.

The authentication server 300 stores the reference information D1ref for user authentication for collating with the user authentication data D1, and the user authentication data D1 input to the IC card reader 201 at the time of user authentication. And the reference information D1ref are collated, and if they match, a process (user authentication process) that permits the use of the business terminal device 200 (or nursing support system) is executed, while if they do not match, the business terminal device 200 (or nursing) is executed. It is configured to perform processing that does not allow the use of the support system).

The measuring device 400 is a device for measuring vital signs of a patient, and examples thereof include a thermometer, a pulse oximeter, a sphygmomanometer, a glucose meter, a pulse meter, and a weight scale. In the present invention, these measuring devices 400 are short-range wireless communication for short-range wireless communication between the measuring unit 401 for measuring the vital sign, the data storage unit 402 for storing the measured vital data, and the IC card reader 201. A unit 403 is provided, and the measured vital data (vital data stored in the data storage unit 402) can be transmitted to the IC card reader 201. That is, the measuring device 400 used in the present invention is a measuring device having a short-range wireless communication function (in other words, having an IC chip 404 having a function of transmitting data to an IC card reader in a non-contact manner). It is composed of.

Then, when the measuring device 400 applied to the present invention transmits vital data, in addition to the vital data, device identification information that can uniquely identify the measuring device 400 (for example, the serial number of the measuring device 400 or the manufacturing). It is configured to transmit D2 (such as a combination of number and model number). The device identification information D2 is preferably configured to be automatically added when the vital data is transmitted, but may be configured to be transmitted in response to a request from the business terminal device 200. Further, the device identification information D2 is composed of information given at the time of manufacturing the measuring device 400, such as the above-mentioned serial number, and information given after the fact at, for example, a medical institution where the measuring device 400 is introduced. You may be. In short, the content of the device identification information D2 can be appropriately changed as long as the information can uniquely identify the measuring device 400.

The vital data identification server 500 is a server computer that identifies whether or not the data Din input to the IC card reader 201 is vital data, and is communicated and connected to the business terminal device 200 or the like via the network N. There is.

The vital data identification server 500 stores the reference information D2ref of the device identification information D2 of the measuring device 400 used in the medical institution, and the data Din input to the IC card reader 201 and the reference information D2ref are stored in the vital data identification server 500. It is collated and it is determined whether or not this reference information D2ref is included in the received data. Then, as a result of this determination, if the reference information D2ref is included in the data Din, it is determined that the data Din is the data including the vital data, while if the reference information D2ref is not included, the data Din is determined. It is configured to determine that it does not contain vital data.

The network N is a computer network that constitutes a LAN (Local Area Network) in the facility of a medical institution. As the network N, a wired LAN or a wireless LAN is appropriately adopted.

Next, in the medical support system configured in this way, using FIG. 2, an information processing method for reading the vital data stored in the measuring device 400 using the IC card reader 201 for user authentication is used. explain.

In the medical support system shown in the present embodiment, when data is input to the IC card reader 201, the medical support system collates the input data with the reference information D1ref for user authentication and the reference information D2ref for device identification. Then, as a result of collation, if data matching the reference information D1ref for user authentication is included, the user authentication process is executed by the authentication server 300, and the data matching the reference information D2ref for device identification is executed. If it is included, the business terminal device 200 executes the reading process of vital data.

Specifically, when data is input to the IC card reader 201 (see Yes in S201 of FIG. 2), it is first determined whether or not the input data Din is the user authentication data D1 (FIG. 2). See S202 in 2).

This determination is made by the authentication server 300. That is, the business terminal device 200 that has received the data Din adds information or the like that identifies the business terminal device 200 to the received data Din and transmits it to the authentication server 300. The authentication server 300 collates the received data with the reference information D1ref for user authentication, determines whether or not data matching the reference information D1ref is included, and if the matching data is included, user authentication is performed. With permission (see Yes in S202 of FIG. 2), a predetermined process (user authentication process) for permitting the use of the business terminal device 200 (or the nursing support system) is executed. This makes it possible to operate the business terminal device 200 (or the nursing support system in the business terminal device 200) that has transmitted the data Din.

On the other hand, when the data received by the authentication server 300 does not include data matching the reference information D1ref (see No in S202 of FIG. 2), the input Din is not the user authentication data D1, so the measuring device. It is determined whether or not the data is 400 vital data (see S204 in FIG. 2).

This determination is made by the vital data identification server 500. That is, when the authentication server 300 determines that the data Din is not the user authentication data D1, the vital data identification server 500 collates the data received via the network N with the reference information D2ref and matches the reference information D2ref. Judge whether or not the data to be used is included. Then, if the matching data is included, it is determined that the data D1 input to the IC card reader 201 is vital data (see Yes in S204 of FIG. 2), and the business terminal device 200 receives the data as vital data. (Reading process of vital data) is executed (see S205 in FIG. 2). As a result, the business terminal device 200 executes predetermined processing according to the instruction of the application, such as reading the data Din input to the IC card reader 201 as vital data and saving the read vital data.

On the other hand, when the data received by the vital data identification server 500 does not include the data matching the reference information D2ref (see No in S204 of FIG. 2), the input Din is the user authentication data D1 and Since it is neither of the vital data, it is regarded as unreadable and a predetermined error process is executed (see S206 in FIG. 2).

As described above, according to the medical support system shown in the present embodiment, when data is input to the IC card reader 201, the user if the input data Din includes the user authentication data D1. While authenticating and permitting the use of the business terminal device 200 or the application, if the device identification information D2 of the measuring device 400 is included, the vital data is read, so that the business terminal device 200 is used for user authentication. The provided non-contact type IC card reader 201 can also be used as an IC card reader for reading vital data, and the IC card reader connected to the business terminal device can be unified.

Further, since both user authentication and vital data reading can be performed by a single IC card reader 201, the number of IC card readers 201 connected to the business terminal device 200 can be reduced, and the portability and operability can be reduced. It is possible to provide an excellent business terminal device 200.

In the above-described embodiment, after determining whether or not the data Din input to the IC card reader 201 includes the user authentication data D1 (after the determination by the authentication server 300), the device is identified. Although the case of determining whether or not the information D2 is included (determining by the vital data identification server 500) is shown, the authentication server 300 and the vital data identification server 500 are configured to simultaneously perform the determination in parallel. It is also possible.

Further, in the above-described embodiment, the case where the storage and collation of the reference information D2ref of the device identification information D2 for the measuring device 400 is configured to be performed by the independent vital data identification server 500 has been shown, but the reference information D2ref has been shown. The storage and collation of the data are performed in a storage area or processor provided in another existing computer communication-connected to the business terminal device 200 via network N, for example, a storage area in the authentication server 300 or another business terminal device 200. It is also possible to omit the vital data identification server 500 by letting the processors centrally or distributedly perform the operation.

Embodiment 2
Next, another embodiment of the present invention will be described with reference to FIGS. 3 and 4.
The medical support system according to the second embodiment is configured to determine the data Din input to the IC card reader 201 without depending on the device identification information D2 transmitted from the measuring device 400. The system is not provided with the vital data identification server 500 as shown in FIG. Since the other configurations are the same as those in the first embodiment described above, the parts having the same configuration are designated by the same reference numerals and the description thereof will be omitted.

In the medical support system shown in the present embodiment, the business terminal device 200 provided with the IC card reader 201 is provided with a program (software) for executing the process shown in FIG.

That is, the business terminal device 200 monitors whether or not a predetermined application for handling patient vital data (in this embodiment, an application for a nursing support system) is activated by setting a program (see S401 in FIG. 4). ).

Then, when a predetermined application is running, that is, when the business terminal device 200 is being used as a nursing support system, the business terminal device 200 receives the data Din input to the IC card reader 201 as vital data. .. In other words, while the nursing support system is running, the IC card reader 201 is treated as a card reader for vital data input, and is in a state of waiting for vital data input (see S402 in FIG. 4). Therefore, when the measuring device 400 is brought close to the IC card reader 201 in this state and the data from the measuring device 400 is input, it is determined that the data is vital data and the data is taken into the nursing support system ( Read) is performed.

On the other hand, when the predetermined application is not started, that is, when the nursing support system is not started, the business terminal device 200 uses the data Din input to the IC card reader 201 as the data for user authentication. Accept. In other words, when the nursing support system is not activated, the IC card reader 201 is treated as a card reader for user authentication and is in a state of waiting for input of user authentication data (see S403 in FIG. 4). Therefore, when the IC card is brought close to the IC card reader 201 in this state and the data from the IC card is input, it is determined that the data is the data for user authentication and the data is transmitted to the authentication server 300. Then, the user authentication is performed by the authentication server 300.

As described above, in the present embodiment, in the business terminal device 200 to which the IC card reader 201 is connected, the IC card reader 201 is used for inputting vital data or user authentication depending on whether or not a predetermined application is running. Since it is automatically switched and used as a device for inputting data for use, the non-contact IC card reader 201 originally provided in the business terminal device 200 for user authentication is used as an IC card for reading vital data. It can also be used as a reader, and the IC card reader connected to the business terminal device can be unified.

Further, since both user authentication and vital data reading can be performed by a single IC card reader 201, the number of IC card readers 201 connected to the business terminal device 200 can be reduced, and the portability and operability can be reduced. It is possible to provide an excellent business terminal device 200.

It should be noted that the above-described embodiment merely indicates a preferred embodiment of the present invention, and the present invention is not limited to these, and various design changes can be made within the scope of the present invention.

For example, in the above-described embodiment, it is shown that the short-range wireless communication is NFC, but various communication standards such as so-called Type-A, Type-B, and Type-F can be adopted as the communication standard of NFC. it can. Along with this, as the IC card reader 201, a card reader corresponding to various standards can be used.
