(Embodiment 1)
FIG. 1 shows a medical product management system 100 according to this embodiment. The medical product management system 100 is a system installed in a medical field to manage the location and inventory of medical products in the medical field. Here, the medical field is a hospital, a clinic, a health center, a welfare facility, or the like, a building, a facility, an equipment, or the like where medical products are used to perform medical treatment. In addition, medical products are equipment and devices used for medical treatment and the like in medical practice. Examples of medical products include syringes, catheters, artificial blood vessels, blood pumps, blood transfusion products, thermometers, sphygmomanometers, endoscopes, gauze, and the like.

As shown in FIG. 1, the medical product management system 100 includes communication sheets 20a to 20c installed in the cabinet 30, a reader / writer 10, a management device 40, a database 50, and a terminal device 60. The communication sheets 20a to 20c and the reader / writer 10 are connected via a coaxial cable 35, the reader / writer 10 and the management device 40 are connected via a LAN cable 11, and the management device 40, the database 50, and the terminal device 60 are connected. Is connected via the LAN cable 12. Further, the management device 40, the database 50, and the terminal device 60 are connected to the medical wholesaler server 90 installed in the medical wholesaler via the external network 80.

Each of the communication sheets 20a to 20c is a sheet-shaped medium (sheet-shaped antenna) that contacts or communicates with a communication device that is in contact with or is close to the surface through a proximity field generated on the surface. Here, the sheet shape means a shape (flat plate shape) having a spread as a two-dimensional surface and a thin thickness. Each of the communication sheets 20a to 20c has a function of an antenna in the reader / writer 10.

The communication sheets 20a to 20c are laid on the surface of the cabinet 30 provided in the medical field on which medical products are placed, that is, on the shelf board (floor surface) of each storage shelf. Various medical products 70a to 70c (in FIG. 1, a package (outer box) containing medical products 70a to 70c is shown as an appearance) are unused in each storage shelf of the cabinet 30. Placed and stored.
Although not shown in FIG. 1, it goes without saying that a communication sheet may be installed in the drawer portion of the cabinet.

In the following, when each of the medical products 70 to be managed such as the medical products 70a to 70c is referred to without distinction, they are collectively referred to as the medical product 70. Similarly, when the communication sheets 20a to 20c are referred to without distinction, they are collectively referred to as the communication sheet 20.

As shown in FIG. 2, each of the medical products 70 placed in the cabinet 30 is attached with an RF tag 71 storing management information of the medical products 70. The management information stored in the RF tag 71 is information about the medical product 70 to which the RF tag 71 is attached, for example, an ID (identification information) of the medical product 70, information indicating the product name, information about the storage location, and use. The deadline, etc. Such management information of the medical product 70 is read from the RF tag 71 by the communication sheet 20 installed at the place where the medical product 70 is placed.

Note that FIG. 2 shows how the RF tag 71 is attached to the package (outer box) of the medical product 70. As described above, depending on the medical product 70, it may be inappropriate to attach the RF tag 71 to the medical product 70 itself. Therefore, when the RF tag 71 is attached to the medical product 70, the RF tag 71 is the medical product 70. In addition to being attached to the medical product itself, the RF tag 71 is also attached to something placed with the medical product 70, such as a package containing the medical product 70. When the RF tag 71 is attached to the package, the position where the RF tag 71 is attached may be either the outer surface or the inner surface of the package.

When the medical product 70 is a relatively small size such as a catheter, a plurality of medical products 70 may be contained in one package. In this case, one RF tag 71 attached to the package containing the plurality of medical products 70 stores common management information regarding the plurality of medical products 70.

The method of attaching the RF tag 71 to the medical product 70 may be any method such as attaching with a sticker, tape, or the like. The position where the RF tag 71 is attached to the medical product 70 can be determined in consideration of the shape and characteristics of the medical product 70 or its package. For example, the RF tag 71 is located closer to the communication sheet 20, that is, a position closer to the lower side than the upper side, in the area to which the RF tag 71 can be attached in the medical product 70 so that the RF tag 71 can be easily read by the communication sheet 20. It is preferable to be attached to.

Further, the RF tag 71 is a passive tag having no self-power supply. That is, the RF tag 71 operates using an electromagnetic wave supplied from the outside (specifically, the communication sheet 20) as an energy source.

The reader / writer 10 reads the management information of the medical product 70 from the RF tag 71 attached to the medical product 70 placed at the place where the communication sheet 20 is installed via the communication sheet 20. Therefore, the communication sheet 20 is installed in various places where the medical product 70 to be managed in the medical product management system 100 is placed. That is, as the place where the communication sheet 20 is installed, only the cabinet 30 is shown in FIG. 1 for easy understanding, but it is not limited to the cabinet 30, and various places where the medical product 70 is placed in the medical field (for example,). It is installed in each of the shelves, chests of drawers, storage boxes, etc. where medical supplies 70 are stored in storages and wards. Further, the place where the communication sheet 20 is installed includes not only a place where the medical product 70 is stored but also a place where the medical product 70 is temporarily placed when it is used, such as an operating room or a doctor's office. ..

Further, the reader / writer 10 can read the management information from the RF tags 71 attached to the plurality of medical products 70 by one communication sheet 20. Therefore, the communication sheet 20 is usually installed in a place where a plurality of medical products 70 are placed, such as a storage shelf of a cabinet 30.

3 (A) and 3 (B) show the configuration of the communication sheet 20.

As shown in the plan view of FIG. 3A, the communication sheet 20 has a sheet-shaped conductor 21 having mesh-shaped openings formed on one surface in the thickness direction. Further, as shown in the cross-sectional view of FIG. 3B, the communication sheet 20 has a sheet-shaped conductor 22 arranged to face the sheet-shaped conductor 21 on the surface on the other side in the thickness direction, and has two layers. It has a dielectric 23 between the sheet-shaped conductors 21 and 22 of the above. A protective sheet 24 such as vinyl chloride is attached to the upper surface of the sheet-shaped conductor 21 in case water is spilled.

The sheet-shaped conductor 21 and the sheet-shaped conductor 22 are each composed of, for example, an aluminum laminate having a thickness of about 32 μm. The dielectric 23 is composed of, for example, a foamed polyolefin having a thickness of about 2 cm. The sheet-shaped conductor 21 and the sheet-shaped conductor 22 are not limited to aluminum laminates, but may be made of metal foils such as copper, silver, and nickel, plating, vapor deposition, and printing. Further, the dielectric 23 is not limited to the foamed polyolefin, and may be made of polyester, polyamide, aromatic polyamide or the like. For example, the dielectric 23 includes an olefin resin (TPO), a styrene resin (SBC), a vinyl chloride resin (TPVC), a urethane resin (PU), an ester resin (TPE), an amide resin (TPAE), and a fluorinated resin (PTFE). It can be composed of an epoxy resin, a phenol resin, a polyphenylene ether resin, or the like. Further, the dielectric 23 may be composed of a fiber structure such as a woven fabric, a knitted fabric, a wet nonwoven fabric, or a dry nonwoven fabric. Further, an insulator (for example, a glass epoxy material) may be used instead of the dielectric 23, or air may be used between the sheet-shaped conductors 21 and 22 without using the dielectric 23 itself.

As the dielectric 23, a dielectric having a relative permittivity of 1.0 to 15, preferably 1.0 to 5.0, and more preferably 1.0 to 3.0 at a frequency of 800 MHz to 10 GHz is used. As the dielectric 23, particularly considering the specific dielectric constant and processability, polyolefins such as polyethylene (PE) and polypropylene (PP), polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), and poly Polyester and polyimide (PI) such as trimethylene terephthalate (PTT) are preferable, and polyester and polyolefin are particularly preferable. Further, the dielectric 23 is preferably a porous material, and examples thereof include foamed polyethylene and foamed polypropylene having a porosity of 50 to 85%. Since the sheet is made of a porous material, the porosity of the sheet increases and the relative permittivity approaches 1, so that stable communication performance can be obtained. As long as it is a porous material, it may be continuously foamed or independently foamed.

The communication sheet 20 can be cut and used as needed. That is, the communication sheet 20 is cut into an appropriate size according to the area of the place where the communication sheet 20 is installed, and is installed at a desired place.

The communication sheet 20 has a connector 25 for connecting to the coaxial cable 35. A reader / writer 10 is connected to the other end of the coaxial cable 35. That is, as shown in FIG. 1, the plurality of communication sheets 20a to 20c installed in the cabinet 30 are connected to the reader / writer 10 via the coaxial cable 35, respectively. Further, as shown in FIG. 3B, the communication sheet 20 has a terminal portion 26 for impedance adjustment at an end portion on the side opposite to the side on which the connector 25 is provided.

The reader / writer 10 transmits an electromagnetic wave to the communication sheet 20, and reads the management information of the medical product 70 from the RF tag 71 attached to the medical product 70 via the proximity field generated by the transmitted electromagnetic wave (reading device). ).

Specifically, the reader / writer 10 transmits electromagnetic waves in the UHF band (radio waves having a wavelength of about 30 cm) to each of the communication sheets 20 installed at each location via the coaxial cable 35 (radio waves having a wavelength of about 30 cm). For example, it is repeatedly transmitted in 1 second). The electromagnetic wave transmitted from the reader / writer 10 propagates inside the communication sheet 20. Then, the electromagnetic wave transmitted inside the communication sheet 20 is leached from the surface of the communication sheet 20 to generate a proximity field.

More specifically, the electromagnetic wave transmitted from the reader / writer 10 is transmitted between the connector 25 and the terminal portion 26 in the dielectric 23 between the two-layer sheet-shaped conductors 21 and 22. Then, the electromagnetic wave transmitted in the dielectric 23 is leached out from the mesh-shaped opening formed in the sheet-shaped conductor 21, so that the electromagnetic wave is leached out from the leaching region 27 (broken line in FIG. 3B) in the immediate vicinity of the sheet-shaped conductor 21. Leaks (leaks out) into the area indicated by. This leached electromagnetic wave (evanescent wave) does not propagate far away and forms a near field in the leaching region 27 in the immediate vicinity of the sheet-shaped conductor 21.

The amount of electromagnetic waves leached from the surface of the sheet-shaped conductor 21, that is, the size of the leaching region 27 is mainly determined by the spacing of the mesh formed on the sheet-shaped conductor 21 and the relative permittivity of the dielectric 23. Since the electromagnetic wave transmitted in the dielectric 23 is shielded without forming a hole on the surface of the communication sheet 20 on the sheet-shaped conductor 22 side, it does not seep out from the sheet-shaped conductor 22 side.

As shown in FIG. 3C, when the medical product 70 is placed at the place where the communication sheet 20 is installed, the RF tag 71 attached to the medical product 70 enters the exudation region 27 where the proximity field is generated. .. When the RF tag 71 approaches the leaching region 27 of the communication sheet 20 in this way, the RF tag 71 detects the proximity field formed on the surface of the communication sheet 20 and displays the stored management information toward the communication sheet 20. Sends the indicated signal. The reader / writer 10 reads the information stored in the RF tag 71 by receiving the signal transmitted from the RF tag 71 via the communication sheet 20.

The reader / writer 10 includes a transmission / reception unit that transmits such electromagnetic waves and receives a signal from the RF tag 71, a control unit that controls the transmission / reception unit, a higher-level management device 40, and a LAN (Local Area Network) cable 11. It is provided with a communication interface for communicating via. The control unit controls the transmission timing of the electromagnetic wave to the communication sheet 20, and directly or processes the read information to connect the upper management device 40 connected by the LAN cable 11 and the management device 40 and the LAN cable 12. The higher-level terminal device 60 connected via the communication interface is notified via the communication interface.

Next, with reference to FIG. 4, the configuration of the management device 40 and the terminal device 60 in the medical product management system 100 will be described.

The management device 40 is an execution unit that executes predetermined processing related to the management of the medical product 70 in the medical product management system 100 based on the reading result of the management information from the RF tag 71 by the reader / writer 10 (reading unit). The management device 40 is composed of a dedicated or general-purpose computer or the like. Alternatively, the management device 40 can be configured by being incorporated in various existing electronic devices.

As shown in FIG. 4, the management device 40 includes a control unit 42, a communication interface 43, a storage unit 44, and an operation unit 45.

The control unit 42 is composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like. The control unit 42 executes various processes in the management device 40 by controlling various functions included in the management device 40 according to a program stored in the ROM.

The communication interface 43 is composed of a LAN port for communicating with the reader / writer 10 via the LAN cable 11, a LAN port for communicating with the database 50 and the terminal device 60 via the LAN cable 12, and the like.
The storage unit 44 is composed of a non-volatile memory such as a flash memory or a hard disk drive. The storage unit 44 stores data generated or acquired by the control unit 42 executing various processes, such as management information of the medical product 70 read from the RF tag 71.
The operation unit 45 includes a power switch of the management device 40, a reset button for initializing settings, and the like.

The control unit 42 collects the management information of the medical product 70 read from the RF tag 71 by the reader / writer 10 via the communication sheet 20, and stores the collected management information in the database 50. Then, the control unit 42 executes the process related to the management of the medical product 70 based on the management information stored in the database 50.

As shown in FIG. 4, the database 50 stores a management table 51 showing management information of the medical product 70 and a schedule 52 showing the usage schedule of the medical product 70. The database 50 is composed of a non-volatile memory such as a hard disk drive.

FIG. 5 shows an example of the management table 51 stored in the database 50. The control unit 42 of the management device 40 collects management information of a large number of medical products 70 read through communication sheets 20 installed at various places in the medical field, and a management table 51 as shown in FIG. Will be generated and updated sequentially.

Specifically, the management table 51 stores information such as ID (identification information), product name code, product name, delivery date, expiration date, status, and location as management information. Hereinafter, each item will be described.

The "ID" is information uniquely set for each medical product 70 so that each of the medical products 70 can be identified.
The "product name code" is a code indicating the product name of the medical product 70 such as a catheter or an artificial blood vessel. Even if the medical product 70 has a different ID, if the product name is the same, the same product name code is set.
The ID and the product name code are stored in the RF tag 71 attached to the medical product 70, for example, and the information read from the RF lag 71 is stored in the management table 51.
The "product name" represents the product name indicated by the product name code so that the user can easily understand what each of the medical products 70 stored in the management table 51 is. The correspondence relationship between the product name code and the product name may be stored in the management device 40 or may be acquired from the cloud server via the external network 80.

The “delivery date” indicates the date on which the medical product 70 is delivered to a medical site such as a hospital. As the delivery date, the date when the RF tag 71 attached to the medical product 70 is first read is stored.
The "expiration date" indicates an expiration date set to ensure that the medical product 70 is used safely and effectively. The expiration date is stored in the RF tag 71 attached to the medical product 70, and the information read from the RF lag 71 may be stored in the management table 51. Alternatively, the management device 40 may acquire from the cloud server via the external network 80 based on the ID.

The "situation" indicates the current status of the medical product 70, specifically, whether or not the medical product 70 currently exists at the place where the communication sheet 20 is installed. When the ID of the medical product 70 is read through any of the communication sheets 20 installed at the medical site, the information "Yes" is stored in the item column of "Status". On the other hand, if the ID of the medical product 70 cannot be read from any communication sheet 20 installed at the medical site, the information "carrying out" is stored in the "status" item column. To.

"Location" indicates the current location of the medical product 70. Specifically, when "Yes" is stored in the "Status" item column, the communication sheet 20 in which the ID of the medical product 70 was last read is installed in the "Location" item column. (For example, storage A, storage B, operating room B, etc.) are stored. On the other hand, when "Bringing out" is stored in the "Status" item column, nothing is stored in the "Location" item column because the location of the medical product 70 is unknown. ..

The control unit 42 of the management device 40 acquires the management information of the medical product 70 from the RF tag 71 via the communication sheet 20 installed at various places in the management table 51 storing such management information. , Will be updated. Specifically, the control unit 42 compares the ID included in the management information read from the RF tag 71 with each ID stored in the management table 51, so that the management information read can be stored in the management table. The database 50 is updated by the procedure shown in the following (1) to (3) while determining whether or not the database already exists in the 51.

(1) When the medical product 70 is brought to the medical site for the first time, for example, at the time of delivery, the management information of the medical product 70 does not exist in the management table 51. In this case, the control unit 42 adds a new row to the management table 51 and stores the read management information in each item column of the management table 51. For example, the control unit 42 stores the read date in the item column of "delivery date" of the management table 51, stores "yes" in the item column of "status", and stores the item column of "location". Stores the place where the communication sheet 20 from which the management information is read is installed.
(2) On the other hand, when the already delivered medical product 70 is stored in the medical field, the management information of the medical product 70 already exists in the management table 51. In this case, the control unit 42 updates the management information of the medical product 70 in the management table 51 with the newly read management information. For example, when the medical product 70 is moved from the storage room A to the storage room B, or when the management information is read by a communication sheet 20 different from the previous one, the control unit 42 has an item of "location" in the management table 51. The column is updated to the place where the communication sheet 20 in which the management information is newly read is installed. On the other hand, if the newly read management information is the same as the previously read management information, the management table 51 is not changed.
(3) Further, when the medical product 70 is taken out and used or discarded, the management information of the medical product 70 cannot be read through the communication sheet 20. Therefore, even though the control unit 42 exists in the management table 51, if there is management information that cannot be read from any communication sheet 20 even after a predetermined time has elapsed, the control unit 42 manages it. The item column of "status" of the medical product 70 in the table 51 is changed to "taken out", and the information stored in the item column of "location" is deleted. When the ID of the medical product 70 whose "status" item column has been changed to "carrying out" is read out again via any of the communication sheets 20, it is said that the medical product 70 has been taken out. Judgment is made, and the item column of "Situation" is returned to "Yes".

By managing the status and location of the medical product 70 in the management table 51 in this way, the inventory status of the medical product 70 can be grasped in real time, and inventory can be automatically performed. Further, since the location of the medical product 70 can be grasped in real time, it is possible to prevent the medical product 70 from being lost. In addition, by recording the number of times and the time when the item column of "situation" is "taken out", information on the frequency of use of the medical product 70 can be obtained.

The information in the management table 51, which is sequentially updated, is transmitted to the terminal device 60 in response to a request from the terminal device 60. The terminal device 60 is a device operated by a user, and is an information processing device such as a PC (Personal Computer), a tablet terminal, or a smartphone.

As shown in FIG. 4, the terminal device 60 includes a control unit 62, a communication interface 63, an operation unit 65, and a display unit 66.

The control unit 62 is composed of a CPU, a ROM, a RAM, and the like. The control unit 62 executes various processes in the terminal device 60 by controlling various functions included in the terminal device 60 according to a program stored in the ROM.

The communication interface 63 is composed of a LAN port or the like for communicating with the management device 40 and the database 50 via the LAN cable 12.
The operation unit 65 is composed of, for example, a keyboard, a mouse, a button, a touch panel, or the like. The operation unit 65 receives various operation instructions input from the user and transmits the received operation instructions to the control unit 62.
The display unit 66 is composed of, for example, a liquid crystal display or the like. The display unit 66 acquires data to be displayed from the control unit 62, such as data received from the management device 40 by the control unit 62, and displays an image showing the acquired data.

A predetermined application program for realizing the management process of the medical product 70 in the medical product management system 100 is installed in the terminal device 60 in advance. The control unit 62 requests the information of the management table 51 from the database 50 according to the application program installed in advance. Then, the control unit 62 acquires the information of the management table 51 stored in the database 50 via the communication interface 63 and displays it on the display unit 66. As a result, the user can obtain information on the location and inventory of the medical product 70 in the medical field in real time.

The terminal device 60 is installed not only in one unit but also in various places where the database 50 can be accessed, both inside and outside the medical site, so that the user can acquire the management information of the medical product 70 from various places. be able to. As a result, the information of the management table 51 stored in the database 50 can be acquired and presented to the users at various locations.

In addition to the management table 51, the database 50 also functions as a schedule storage unit for storing the schedule 52 in which the medical product 70 is used.

FIG. 6 shows an example of the schedule 52 stored in the database 50. The schedule 52 stores information on the date and time and place where the medical product 70 is used, the medical product 70 to be used, and the number thereof at the medical site where the medical product management system 100 is installed. For example, the schedule 52 shown in FIG. 6 first states that medical products 70 such as 3 catheters and 5 syringes are required in the operating room A between 10:00 and 12:00 on July 1, 2015. Shows.

Such a schedule 52 can be input and updated by a user, for example, by operating the operation unit 65 of the terminal device 60. Alternatively, the schedule in which the medical product 70 is used in the medical field is managed by the cloud server, and the schedule 52 can be sequentially acquired from the cloud server at an appropriate timing and updated in the database 50. ..

Next, the flow of the medical product management process executed in the management device 40 will be described with reference to the flowchart shown in FIG. 7.

Before the medical product management process shown in the flowchart of FIG. 7 starts, the RF tag 71 is attached to the medical product 70 to be managed, and the communication sheet 20 is installed at each place of the medical site where the medical product 70 is placed. back. Then, when the power is turned on in each of the management device 40 and the reader / writer 10 connected to the installed communication sheet 20, information can be read from the RF tag 71 via the communication sheet 20. The medical product management process shown in the flowchart of No. 7 is started.

When the medical product management process starts, the control unit 42 of the management device 40 determines whether or not the reading timing for reading the management information of the medical product 70 from the RF tag 71 has arrived via the communication sheet 20 (step S11). .. This reading timing repeatedly arrives at a predetermined cycle (for example, 1 second). When the read timing has not arrived (step S11; No), the control unit 42 stops the process in step S11 and waits until the read timing arrives.

When the reading timing arrives (step S11; Yes), the control unit 42 reads the management information of the medical product 70 from the RF tag 71 via the communication sheets 20a to 20c (step S12). Specifically, the control unit 42 transmits electromagnetic waves in the UHF band to the reader / writer 10 connected to the management device 40 to each of the communication sheets 20a to 20c connected to the reader / writer 10. Command. When the RF tag 71 attached to the medical product 70 to be managed detects an electromagnetic wave transmitted from the reader / writer 10, a signal indicating management information of the medical product 70 stored in the RF tag 71 is transmitted to the communication sheet 20. send. The reader / writer 10 receives the signal indicating the management information transmitted from the RF tag 71 via the communication sheet 20 and transmits it to the management device 40. In step S12, the control unit 42 of the management device 40 acquires the management information of the medical product 70 to be managed by reading the RF tag 71 via the reader / writer 10 in this way.

In the above description, it is assumed that the reading timing is common to the plurality of communication sheets 20a to 20c. However, the reading timing may be different among the plurality of communication sheets 20a to 20c. In that case, the control unit 42 determines in step S11 whether or not the reading timing of any of the plurality of communication sheets 20a to 20c has arrived. Then, each time the reading timing of any one of the plurality of communication sheets 20a to 20c arrives, the above-mentioned reading process is individually executed for the communication sheet 20 for which the reading timing has arrived.

When the management information of the medical product 70 is read from the RF tag 71, the control unit 42 updates the database 50 with the read management information (step S13). That is, the control unit 42 adds management information to the management table 51 shown in FIG. 5, for example, when the medical product 70 is newly delivered, and when the location of the medical product 70 moves. The item column of "location" is rewritten with the information of the new place, and when the medical product 70 is taken out, the item column of "situation" is rewritten with the information indicating to that effect. In this way, the control unit 42 updates the management table 51 stored in the database 50 with the latest information.

When the database 50 is updated, the control unit 42 refers to the schedule 52 in which the medical product 70 is used, which is stored in the database 50 (step S14). Then, the control unit 42 determines whether or not the current location of the medical product 70 is appropriate (step S15).

Specifically, when the medical product 70 defined in the schedule 52 stored in the database 50 is used, the control unit 42 uses the management information of the medical product 70 as the place where the medical product 70 is used. If it cannot be read through the communication sheet 20 installed in the medical product 70, it is determined that the location of the medical product 70 is not appropriate. The place where the medical product 70 is used is a room or space where a medical treatment is performed by using the medical product 70, for example, an operating room or an examination room.

For example, in the example of schedule 52 shown in FIG. 6, medical products 70 such as 3 catheters and 5 syringes are required in the operating room A between 10:00 and 12:00 on July 1, 2015. In this example, the control unit 42 uses the communication sheet 20 installed in the operating room A when the time is 10 o'clock on July 1st, or at a predetermined time (for example, 10 minutes before). If the management information of the medical product 70 such as 3 catheters and 5 syringes cannot be read, it is determined that the location of the medical product 70 is not appropriate. In this way, the control unit 42 refers to the schedule 52 and determines whether or not the required number or more of the necessary medical products are present at the required place at each time point defined in the schedule 52.

When it is determined that the location of the medical product 70 is not appropriate (step S15; No), the control unit 42 issues a warning (step S16). For example, the control unit 42 transmits a predetermined message indicating a warning to the terminal device 60, and causes the display unit 66 of the terminal device 60 to display a warning screen as shown in FIG. 8, for example. This allows the user to recognize that the required medical product 70 is in short supply. Note that FIG. 8 shows an example in which one catheter is missing in the operating room A. Such a warning is transmitted and displayed to the terminal device 60 installed in a place where the missing medical product 70 is used, such as an operating room or an examination room, or a terminal device 60 installed near the place. It is more effective to be done.

In this way, by issuing a warning when the location of the medical product 70 is not appropriate, it is possible to prevent a shortage of the medical product 70 when it is used. It also prevents the wrong use of the medical product 70.

On the other hand, in step S15, when the medical product 70 defined in the schedule 52 stored in the database 50 is used, the management information of the medical product 70 is installed at the place where the medical product 70 is used. When read through the communication sheet 20, the control unit 42 determines that the location of the medical product 70 is appropriate (step S15; Yes). In this case, since it is not necessary to issue a warning, the control unit 42 skips the process of step S16.

Next, the control unit 42 determines whether or not the medical product 70 should be replenished (step S17). That is, when the medical product 70 is a consumable product consumed in the medical field, it is not allowed that the inventory is insufficient. It is also not desirable that the inventory is excessive. Therefore, the control unit 42 checks the inventory of each medical product 70 based on the management information of the medical product 70 read by the reader / writer 10 and stored as the management table 51 in the database 50, and whether it is necessary to replenish it. Judge whether or not.

A plurality of determination criteria can be set as the determination criteria as to whether or not the medical product 70 should be replenished. For example, the control unit 42 uses the medical product 70 as a first determination criterion when the inventory amount of the medical product 70 determined based on the management information stored in the management table 51 falls below a predetermined threshold value. Should be replenished. That is, the control unit 42 calculates the number of medical products 70 stored in the latest management table 51 for each product name, and acquires the amount of stock currently remaining in the medical field for each product name (for example, the stock amount of catheters). 10 pieces, the stock amount of artificial blood vessels is 5 pieces, etc.). Then, the acquired inventory amount is compared with a predetermined threshold value. This threshold can be set individually for each product name, for example.

Further, as a second determination criterion, the control unit 42 determines based on the inventory amount of the medical product 70 determined based on the management information stored in the management table 51 and the schedule 52 stored in the database 50. It is determined that the medical product 70 should be replenished. That is, the control unit 42 predicts whether or not the inventory of any medical product 70 will be insufficient in the near future, considering not only the current inventory amount but also the schedule 52 in which the medical product 70 is used. .. For example, when a large amount of medical product 70 is planned to be used, replenishment is required even if the current inventory amount of the medical product 70 is equal to or more than the threshold value. In order to be able to execute the order processing even in such a case, the control unit 42 further considers not only the current inventory amount of the medical product 70 but also the amount of the medical product 70 scheduled to be used, and the medical product It is determined whether or not 70 should be replenished.

When it is determined that the medical product 70 needs to be replenished (step S17; Yes), the control unit 42 orders the medical product 70 to be replenished from the server of the ordering party (step S18). That is, the control unit 42 sends information on the product name of the medical product 70 to be replenished and the number thereof to the medical wholesaler server 90 installed in the medical wholesaler handling the medical product 70 to be replenished via the external network 80. Send an order mail including. In this way, since the order processing is automatically executed at the required timing, the user can efficiently maintain the inventory within an appropriate range without being bothered by inventory management.

On the other hand, when it is determined in step S17 that the replenishment of the medical product 70 is not necessary (step S17; No), it is not necessary to order the medical product 70. Therefore, the control unit 42 skips the process of step S18.

After that, the control unit 42 returns the process to step S11. Then, in step S11, the control unit 42 waits until the next reading timing arrives, and when the next reading timing arrives, the process of steps S12 to S18 described above is repeated. In this way, the management device 40 sequentially reads management information via the communication sheet 20 and manages the location and inventory of the medical product 70 in the medical field while keeping the database 50 up-to-date.

As described above, in the medical product management system 100 according to the present embodiment, the communication sheet 20 in which a proximity field is generated by leaching the electromagnetic wave transmitted inside from the surface is placed in a place where the medical product 70 is placed in the medical field. Once installed, the reader / writer 10 reads the management information of the medical product 70 from the RF tag 71 attached to the medical product 70 via the communication sheet 20. Then, based on the read management information, the location and inventory of the medical product 70 in the medical field are managed. Since the communication sheet 20 can be easily introduced and installed in various places including the existing storage means such as the cabinet 30, the location of the medical product 70 in the medical field can be widely grasped. Therefore, it is possible to prevent shortage, misuse, loss, shortage of medical products 70 due to omission of order, etc. with high accuracy.

(Embodiment 2)
In the first embodiment, the configuration in which the medical product 70 is directly arranged on the communication sheet 20 has been described. However, in such a configuration, the reader / writer 10 may not be able to properly read the management information of the medical product 70 from the RF tag 71. In this embodiment, an example in which a spacer is provided between the communication sheet 20 and the medical product 70 in order to improve the reading accuracy of the management information of the medical product 70 will be described.

First, the cause of the decrease in the reading accuracy of the management information will be described. It is conceivable that a communication jammer that interferes with the communication between the reader / writer 10 and the RF tag 71 is arranged near the upper surface of the communication sheet 20 as a cause of the deterioration of the reading accuracy of the management information. The communication jammer is, for example, a noise source that generates noise that interferes with communication, or a conductor member that interferes with communication.

The noise source is, for example, a charger for charging an object to be charged (particularly, a charging circuit built in the charger). The object to be charged may be the medical product 70 or an article unrelated to the medical product 70. The charger may be a type built in the charging object or a type used by being attached to the charging object. The conductor member is a member composed of conductors. The conductor member may be a member constituting the medical product 70, or may be a member unrelated to the medical product 70.

In the present embodiment, it is assumed that the charging object is the medical product 70d, and the charger 72d is built in the medical product 70d. That is, in the present embodiment, there is an example of reading the management information of the medical product 70d from the RF tag 71d attached to the medical product 70d while the medical product 70d having a built-in charger 72d is being charged on the communication sheet 20a. explain. Further, in the present embodiment, the conductor member is a conductor portion 76e that constitutes a part of another medical product 70e. That is, in the present embodiment, an example in which the medical product 70e including the conductor portion 76e is arranged on the communication sheet 20a between the medical product 70d and the reader / writer 10 will be described.

FIG. 9 shows the medical product management system 110 according to the present embodiment. In the medical product management system 110, the medical product 70d and the medical product 70e are arranged on the communication sheet 20a instead of the two medical products 70a, and the outlet 31 for supplying electric power for charging the medical product 70d is a cabinet. It differs from the medical product management system 100 in that the spacers 28a, 28b, and 28c are provided on the communication sheets 20a, 20b, and 20c, respectively. That is, in the present embodiment, the spacer 28a is provided between the communication sheet 20a and the medical product 70d and the medical product 70e, and the spacer 28b is provided between the communication sheet 20b and the four medical products 70b, and the communication sheet is provided. A spacer 28c is provided between the 20c and the two medical products 70c.

The outlet 31 is provided in the cabinet 30 and is an outlet for supplying AC power to the medical product 70d. The power plug 75d included in the power cord 74d is inserted into the outlet 31. The spacer 28a is a member for securing a space between the communication sheet 20a and the medical product 70d and the medical product 70e. The spacer 28a is a member arranged so as to be overlapped on the communication sheet 20a so that the noise generation source and the conductor member do not come too close to the sheet-shaped conductor 21 included in the communication sheet 20a. The spacer 28b and the spacer 28c have the same configuration and function as the spacer 28a.

The spacer 28a is preferably made of a material or structure that secures a space between the noise source or the conductor member and the communication sheet 20a without affecting the radio waves used for communication as much as possible. Therefore, it is desirable that the spacer 28a has a dielectric constant and a dielectric loss tangent as small as possible. Further, the medical product 70d and the medical product 70e are placed on the spacer 28a. Therefore, it is desirable that the spacer 28a is made of a sufficiently durable material so as to withstand the load of the medical product 70d or the medical product 70e. Assuming that the mass of a general medical product is about ² to 3 kg and the installation area is about 3 cm 2, the load per unit area is 64 N / cm ^{2 to} 96 N / cm ² (6.53 kgf / cm). The strength may be such that deformation does not occur even when a load of about ^{2 to} 9.8 kgf / cm ^{2) is applied.}

The spacer 28a has a structure having a high porosity, and is preferably made of a high-strength material (for example, plastic). Further, since the spacer 28a is overlapped with the communication sheet 20a, it is preferable that the shape of the surface orthogonal to the thickness direction is substantially the same as the shape of the communication sheet 20a. The spacer 28a is preferably a hollow plate-shaped member formed of a high-strength resin such as polypropylene, polystyrene, polyethylene terephthalate, or polycarbonate, and has a particularly low dielectric constant, low dielectric loss tangent, moldability, and the like. From this point of view, polypropylene is preferable.

That is, the spacer 28a is composed of a high-strength resin and air, and the higher the ratio of the volume of air to the total volume of the spacer 28a, the more preferable (for example, 70% or more). This is because the higher the ratio, the lower the permittivity and the dielectric loss tangent. Typically, the spacer 28a is preferably a plastic corrugated cardboard (corrugated cardboard sheet formed of plastic as a material, commonly known as corrugated plastic) represented by plastic pearl (registered trademark) or sample ply (registered trademark). The spacer 28a may be a porous resin plate or a plate-like member having a structure like a jungle gym framed by a high-strength material.

The medical product 70d is a medical product that has a charging function and operates with charged electric power. The medical product 70d is, for example, an instrument equipped with an electronic circuit (for example, a sphygmomanometer). As shown in FIG. 10A, the medical product 70d includes a charger 72d, a storage battery 73d, and a power cord 74d. The charger 72d is a device built in the medical product 70d and stores the electric charge supplied from the outlet 31 via the power cord 74d in the storage battery 73d. The charger 72d includes a charging circuit (not shown). The charger 72d converts the AC power supplied from the outlet 31 into DC power, and charges the storage battery 73d with the DC power. The charger 72d emits a high frequency of about several hundred kHz as noise while charging the storage battery 73d.

The storage battery 73d stores electric power that is a power source for the medical product 70d, and discharges the stored electric power when the medical product 70d operates. The storage battery 73d is charged by the charger 72d. The power cord 74d supplies the electric power stored in the storage battery 73d to the storage battery 73d from the outlet 31. The power cord 74d includes a plug 75d that is plugged into an outlet 31. The RF tag 71d is attached to the medical product 70d.

As shown in FIG. 10B, the medical product 70e is a medical product including the conductor portion 76e. The conductor portion 76e is made of a conductor, that is, a metal. The conductor portion 76e is, for example, a wiring, a housing, a metal fitting, or the like, and may be a metal for achieving any purpose. The RF tag 71e is attached to the medical product 70e.

Next, a method of protecting the communication between the reader / writer 10 and the RF tag 71d from the noise generation source and the conductor member by the spacer 28a will be described. Hereinafter, an example of reading management information from the RF tag 71d attached to the medical product 70d will be described. First, with reference to FIG. 11A, a state of communication in the case where the spacer 28a is not present will be described as a comparative example.

As shown in FIG. 11A, in the absence of the spacer 28a, the medical product 70d and the medical product 70e are directly arranged on the communication sheet 20a. Here, it is assumed that the medical product 70e is arranged between the medical product 70d and the connector 25. First, in order to facilitate understanding, a case where the medical product 70d is not being charged and the medical product 70e is not arranged on the communication sheet 20a will be described.

In this case, the RF tag 71d included in the medical product 70d is arranged in the exudation region 27. Therefore, when the reader / writer 10 injects radio waves into the communication sheet 20 via the connector 25, the radio waves reach the RF tag 71d. Then, the RF tag 71d radiates a radio wave including management information in response to receiving the radio wave. The radio wave including this management information propagates in the communication sheet 20 or in the air and is supplied to the reader / writer 10. That is, when the medical product 70d is not being charged and the medical product 70e is not arranged on the communication sheet 20a, it can be expected that the management information of the medical product 70d is read normally.

Next, a case where the medical product 70d is being charged and the medical product 70e is not arranged on the communication sheet 20a will be described. First, as shown in FIG. 11A, the distance (d1) between the charger 72d and the sheet-shaped conductor 21 included in the communication sheet 20a is quite short, and the charger 72d is arranged in the leaching region 27. And. Here, the charger 72d included in the medical product 70d emits high frequency as noise. In this case, the charger 72d (the charging circuit included in the charger 72d) and the sheet-shaped conductor 21 are coupled, and the noise emitted from the charger 72d is injected into the sheet-shaped conductor 21. As a result, the radio wave emitted from the reader / writer 10 does not properly reach the RF tag 71d, or the radio wave radiated from the RF tag 71d does not reach the reader / writer 10 properly, so that the management information is appropriate. It may not be readable. That is, if the medical product 70d is being charged and the medical product 70e is not arranged on the communication sheet 20a, the management information may not be read normally.

Next, a case where the medical product 70d is being charged and the medical product 70e is arranged on the communication sheet 20a will be described. In this case, the charger 72d included in the medical product 70d emits high frequency as noise. Therefore, as described above, the management information may not be read normally due to the influence of the noise radiated from the charger 72d. Further, in this case, the distance (d2) between the conductor portion 76e included in the medical product 70e and the sheet-shaped conductor 21 included in the communication sheet 20a is considerably short. Therefore, the conductor portion 76e is included in the seepage region 27, and the conductor portion 76e and the sheet-shaped conductor 21 may be bonded to each other. As a result, there is an increased probability that the radio wave emitted from the reader / writer 10 does not properly reach the RF tag 71d, or the radio wave radiated from the RF tag 71d does not properly reach the reader / writer 10. That is, when the medical product 70d is being charged and the medical product 70e is arranged on the communication sheet 20a, there is a high possibility that the reading of the management information is not normally executed.

If the medical product 70d is not being charged and the medical product 70e is arranged on the communication sheet 20a, the management information may not be read normally due to the influence of the conductor portion 76e.

Next, with reference to FIG. 11B, the state of communication when the spacer 28a is present will be described.

As shown in FIG. 11B, when the spacer 28a is present, the medical product 70d and the medical product 70e are arranged on the communication sheet 20a via the spacer 28a. First, when the medical product 70d is not being charged and the medical product 70e is not arranged on the communication sheet 20a, the reader / writer 10 has no influence on the noise radiated from the charger 72d or the conductor portion 76e. It can be expected that the reading of management information will be executed normally.

Next, a case where the medical product 70d is being charged and the medical product 70e is not arranged on the communication sheet 20a will be described. In this case, the charger 72d included in the medical product 70d emits high frequency as noise. However, the distance (d1) between the charger 72d and the sheet-shaped conductor 21 included in the communication sheet 20a is not so short, and is at least the thickness of the spacer 28a or more. As a result, the charger 72d is arranged outside the leaching area 27. Therefore, the charger 72d and the sheet-shaped conductor 21 are difficult to bond, or even if they are bonded, they are not strongly bonded, and the noise emitted from the charger 72d is not so injected into the sheet-shaped conductor 21.

As a result, the probability that the radio wave emitted from the reader / writer 10 does not properly reach the RF tag 71d or the radio wave radiated from the RF tag 71d does not reach the reader / writer 10 properly becomes low. That is, when the medical product 70d is being charged and the medical product 70e is not arranged on the communication sheet 20a, it is unlikely that the management information is normally read.

Next, a case where the medical product 70d is being charged and the medical product 70e is arranged on the communication sheet 20a will be described. In this case, the charger 72d included in the medical product 70d emits a high frequency as noise, but as described above, it is unlikely that the management information is normally read due to the influence of the noise. Further, the distance (d2) between the conductor portion 76e included in the medical product 70e and the sheet-shaped conductor 21 included in the communication sheet 20a is not so short, and is at least the thickness of the spacer 28a or more. Here, it is assumed that the conductor portion 76e is arranged outside the leaching region 27. Then, the possibility that the conductor portion 76e and the sheet-shaped conductor 21 are bonded is low, and even if they are bonded, the bond is not so strong. As a result, it is unlikely that the management information is read normally due to the influence of the conductor portion 76e. That is, when the medical product 70d is being charged and the medical product 70e is arranged on the communication sheet 20a, it is unlikely that the management information is normally read due to the influence of noise and the influence of the conductor portion 76e.

When the medical product 70d is not being charged and the medical product 70e is arranged on the communication sheet 20a, it is unlikely that the management information is normally read due to the influence of the conductor portion 76e.

In the present embodiment, the distance between the charger 72d, which is a noise source, and the sheet-shaped conductor 21 and the distance between the conductor portion 76e, which is a conductor member, and the sheet-shaped conductor 21 are at least the spacer 28a. It will be thicker than the thickness of, and will not be so short. As a result, the noise source and the conductor member are arranged outside the leaching region 27. Therefore, according to the present embodiment, it is possible to prevent the reader / writer 10 from deteriorating the reading accuracy of the management information due to the influence of the noise generation source and the conductor member.

The presence of the spacer 28a also increases the distance between the RF tag 71d (or RF tag 71e) and the sheet-shaped conductor 21. However, if the RF tag 71d (or RF tag 71e) is included in the leaching region 27, the management information can be read normally even if these distances are a little long. Further, even if the noise source and the conductor member are arranged in the leaching region 27, d1 and d2 become longer to some extent due to the presence of the spacer 28a, so that the deterioration of the reading accuracy of the management information is suppressed to some extent. Can be done.

Further, the frequency of the radio wave used for communication (for example, 800 MHz to 10 GHz) is several thousand to several tens of thousands times higher than the frequency of noise generated by the charger 72d (for example, about several hundred kHz). Therefore, the attenuation characteristics and the resonance frequency are completely different between the radio wave used for communication and the noise. Therefore, even if the spacer 28a is provided to significantly reduce the influence of noise, the radio waves used for communication do not always propagate normally. That is, it is preferable to select the thickness, material, and structure of the spacer 28a so that the influence of noise and the conductor member is significantly attenuated within the range in which the radio wave used for communication normally propagates.
The thickness of the spacer is generally set to about 10 mm, and may be adjusted in units of 1 mm, for example, while considering the degree of propagation of radio waves used for communication, noise attenuation, and the like.

Not limited to this. For example, the communication sheet 20 is installed on the upper side or the lateral side (for example, the lower surface of the upper plate or the side surface of the lateral plate with respect to the medical product 70) with respect to the medical product 70 that reads the management information from the RF tag 71. You may.

There is also the possibility of giving. Even in such a case, the presence of the spacer 28a can be expected to reduce the influence of noise generated by the charger 72d.

Further, in the second embodiment, the example in which the conductor member is a part of the medical product 70e has been described, but the conductor member may be unrelated to the medical product 70e. Even in such a case, the presence of the spacer 28a can be expected to reduce the influence of the conductor member.

Further, in the second embodiment, the example in which the spacer 28a and the communication sheet 20a are separate bodies has been described, but the spacer 28a and the communication sheet 20a may be integrally formed.

Not only can it be provided as a management device and a terminal device provided with a configuration for realizing the function according to the present invention, but by applying a program, an existing information processing device or the like can be used as a medical product management system according to the present invention. It can also function as a constituent management device and terminal device. That is, by applying the program for realizing each functional configuration by the management device 40 and the terminal device 60 exemplified in the above embodiment so that the CPU or the like that controls the existing information processing device or the like can be executed, the present invention is made. It can function as a management device and a terminal device constituting the medical product management system according to the above.

Moreover, the method of applying such a program is arbitrary. The program can be stored and applied in a computer-readable storage medium such as a flexible disc, a CD (Compact Disc) -ROM, a DVD (Digital Versatile Disc) -ROM, or a memory card. Further, the program can be superimposed on the carrier wave and applied via a communication medium such as the Internet. For example, the program may be posted and distributed on a bulletin board system (BBS: Bulletin Board System) on a communication network. Then, by starting this program and executing it in the same manner as other application programs under the control of the OS (Operating System), the above processing may be executed.
