[0010] Figure 1 is an explanatory diagram showing the configuration of a drug use support system 2 using a patch 1 according to one embodiment of the present invention, and Figure 2 is an explanatory diagram showing an example of use of the drug use support system 2. Figure 3 is a plan view showing the configuration of the patch 1, Figure 4 is a cross-sectional view showing the configuration of the patch 1, and Figure 5 is a bottom view showing the configuration of the patch 1. Figure 6 is a plan view showing the patch 1 in a packaging bag 25, and Figure 7 is an explanatory diagram showing the packaging bag 25 opened. Figure 8 is an explanatory diagram showing an example of use of the patch 1.

[0011] The patch 1, for example, is formed so that a communication device 11 is provided on the patch body 10, which is the drug itself, enabling wireless communication with a communication terminal. As shown in Figures 1 and 2, such a patch 1 is used, for example, in a drug use support system 2 that assists (manages) when a patient uses the patch 1. First, the drug use support system 2 will be described.

[0012] As shown in Figures 1 and 2, the drug use support system 2 comprises a patch 1, a management server 12, and a terminal 13. As shown in Figure 2, the drug use support system 2 uses the terminal 13 to read a code 28, such as a QR code (registered trademark), as first trigger information, and stores the administration method of the patch body 10 determined by the medical institution in the terminal 13. Furthermore, using this as a trigger, it retrieves management information of the patch body 10, such as the type, description, and image of the patch body 10, from the management server 12 and stores it in the terminal 13. The drug use support system 2 also retrieves second trigger information from the communication device 11, and based on this retrieved information, the terminal 13 retrieves and / or determines the usage status of the patch 1, and manages the use of the drug by the user (patient). Furthermore, when terminal 13 acquires second trigger information, the drug use support system 2 displays the screen of an application that manages drug use support based on stored management information on terminal 13, displays the management information of the patch body 10 on the application screen, and provides the patient with the management information of the patch body 10 by making it visible to the patient. In addition, the drug use support system 2 determines the patient's use of the patch body 10 based on the usage status acquired from the communication device 11 through communication with the communication device 11, the QR code 28, and the management information acquired from the management server 12, and if it is determined that the use is incorrect, terminal 13 issues an alert to the patient.

[0013] As shown in FIG. 1, in the drug use support system 2, information is transmitted and received between each component by communication means. As a specific example, it is assumed that the communication device 11 and the terminal 13 are connected by a relatively short-range wireless communication means such as Bluetooth (registered trademark). Also, as a specific example, the management server 12 and the terminal 13 are connected via the network NW through a mobile communication network such as 4G or 5G, or a relatively long-range wireless communication line such as Wimax. Note that the management server 12 and the terminal 13 may be connected via a wired communication line such as a USB (Universal Serial Bus) or a LAN (Local Area Network) connection using a cable. Further, the communication device 11, the management server 12, and the terminal 13 are not limited to the above-described communication means, and may be configured to be connected by other communication means.

[0014] Next, the configuration of the patch 1 will be described. As shown in FIGS. 3 and 4, the patch 1 includes a patch body 10 and a communication device 11 detachably provided on the patch body 10.

[0015] As shown in FIG. 6, the patch 1 includes, for example, a packaging bag 25, and the patch body 10 and the communication device 11 are accommodated and sealed in the packaging bag 25. When the patch 1 is, for example, prescribed from a pharmacy, the patches 1 packaged in a predetermined number of packaging bags 25 are accommodated in a management medicine bag 26 together with an instruction sheet 27 as shown in FIG. 2. Also, as shown in FIG. 7, the patch 1 is used by opening the packaging bag 25 and taking it out from the packaging bag 25 during use.

[0016] The patch body 10 is a patch used for various diseases and is attached to the human body. The patch body 10 is used, for example, in the treatment of bronchial asthma, ischemic heart disease, hypertension, overactive bladder, Alzheimer's disease, Parkinson's disease, attention deficit / hyperactivity disorder, schizophrenia, depression, postmenopausal osteoporosis, nausea, allergy, analgesia, smoking cessation, infertility, etc. The patch body 10 delivers a drug into the patient's body by transdermal absorption. The type, time, frequency, etc., of use of the patch body 被定められる。

[0017] As a specific example, as shown in Figures 3 and 4, the patch body 10 comprises a sheet-like support 21, an ointment 22 provided on one main surface of the support 21, and a protective film 23 that protects the surface of the ointment 22. The patch body 10 is, for example, Estrana Tape (manufactured by Hisamitsu Pharmaceutical Co., Ltd.).

[0018] The support 21 has an adhesive 22 on one main surface. The support 21 also has a communication device 11 on the other main surface. The support 21 is formed of an adhesive material, or an adhesive layer is formed on the surface on which the communication device 11 is provided, so that the communication device 11 can be attached and detached. For example, in a support 21 to which the communication device 11 can be attached and detached, an adhesive may be provided on the surface on which the communication device 11 is provided, or the entire support 21 may be formed of an adhesive material. Specifically, the support 21 may be formed of an adhesive pad or include a layer containing an adhesive polymer. The support 21 may also be formed of a material that has the function of shielding electromagnetic waves.

[0019] The support 21 has a plaster body 22 on one main surface and a communication device 11 on the other main surface. The shape of the main surface of the support 21 is the same as the shape of the plaster body 22 and the communication device 11, or it is formed to be larger than the plaster body 22 and the communication device 11. Specifically, the main surface of the support 21 is formed in a rectangular shape that is larger than the communication device 11 and the plaster body 22. The support 21 is formed in a rectangular shape.

[0020] The ointment 22 is formed from a drug and an adhesive. The ointment 22 is configured to allow transdermal absorption of the contained drug upon contact with the skin. The shape of the ointment 22 is formed to be the same size as or slightly smaller than the support 21 in the main surface direction, and larger than the communication device 11. As shown in Figure 5, the ointment 22 is formed, for example, in an elliptical shape. As shown in Figure 5, the length of the major axis and the length of the minor axis of the elliptical shape of the ointment 22 are set to be the same as or slightly smaller than the long side and short side of the support 21, and it is formed to be larger than the communication device 11.

[0021] The protective film 23 protects the ointment 22 by covering it before it is applied to the patient's skin. When the ointment 22 is applied to the patient's skin, the protective film 23 is peeled off from the ointment 22, as shown in Figure 8. The protective film 23 is formed in a shape that covers at least the ointment 22. Therefore, the protective film 23 is formed in a shape that is larger than, for example, the communication device 11. Also, the protective film 23 faces the communication device 11, which is provided on the support 21, in the thickness direction. Here, the thickness direction is, for example, the same direction as the stacking direction of the communication device 11, the support 21, and the ointment 22.

[0022] The protective film 23 is an electromagnetic wave shielding material formed from, for example, a material having the function of shielding electromagnetic waves. For example, the protective film 23 has shielding properties that shield electromagnetic waves. When the protective film 23 is protecting the plaster body 22, it shields electromagnetic waves from the communication device 11 provided on the support 21, or disables communication for the communication device 11. For example, when the protective film 23 is attached to the plaster body 22, it disables communication for the communication device 11, and when it is peeled off from the plaster body 22, the communication device 11 is activated and becomes communication-enabled. Such a protective film 23 is formed from, for example, aluminum foil, metal vapor-deposited film, hydrogel film, etc.

[0023] The packaging bag 25 packages and seals one or more adhesive patch bodies 10. The packaging bag 25 is an electromagnetic wave shielding material formed of a material that has the function of shielding electromagnetic waves. For example, the packaging bag 25 has shielding properties that shield electromagnetic waves. When the adhesive patch body 10 is packaged in the packaging bag 25, the packaging bag 25 shields electromagnetic waves from the communication device 11 provided on the support 21, or disables communication for the communication device 11.

[0024] As shown in FIG. 2, the medicine bag 26 is, for example, a bag on which information such as the patient's name, usage, dosage, date of dispensing, name of the pharmacist who dispensed the medicine, name and location of the pharmacy or hospital or clinic where the medicine was dispensed, etc. is displayed. As shown in FIG. 2, the instruction sheet 27 is a material for patients on which medicine information such as the name of the medicine, efficacy, usage, dosage, treatment schedule, etc. is displayed.

[0025] In addition, a code 28 that associates information with the patch body 10 is provided on at least one of the patch body 10, the communication device 11 provided on the patch body 10, the packaging bag 25 that packages the patch body 10, the medicine bag 26, and the instruction sheet 27, by printing or attaching a printed seal, etc.

[0026] The code 28 is, for example, a one-dimensional code or a two-dimensional code, and as a specific example, it is a QR code. Hereinafter, the code 28 will be described as the QR code 28. The QR code 28 is the first trigger information for acquiring information on the patch body 10 to be managed in the terminal 13. The QR code 28 is encoded with information on the patch body 10. Here, the information on the patch body 10 is, for example, information on the patch body 10 itself, information such as the administration method predetermined for the patch body 10, or information on the usage method (usage, dosage, treatment schedule) of the patch body 10 according to the patient, etc., which is information determined by a doctor or pharmacist for each patient regarding the use of the medicine. Note that since the first trigger information only needs to be associated with the information acquired by the terminal 13 from the management server 12, it may be information on the patient instead of information on the patch body 10. That is, the first trigger information may include other information in addition to the information on the patch body 10, or may be the information on the patch body 10 itself.

[0027] The communication device 11 communicates wirelessly with the terminal 13. The radio wave method of the communication device 11 is a general one; the format is not limited as long as the terminal 13 can read the recorded information, and any of the frequency bands 433MHz, 900MHz, or 2.45GHz may be used. The wireless communication technology used in the communication device 11 is, for example, Bluetooth® or Bluetooth Low Energy (BLE)®. The communication device 11 may be, for example, an active tag or a passive tag.

[0028] If the communication device 11 is an active tag, it may have a battery or power supply circuit, or it may be a tag that generates energy from the environment. Preferably, the communication device 11 is a battery-less tag that generates energy from the environment. That is, the communication device 11 is a wireless tag that operates by obtaining energy from ambient electromagnetic waves. For example, an example of an energy-generating wireless tag is the IoT sensing label "Wiliot IoT Pixel" (manufactured by Wiliot). Some communication devices 11 also have a built-in temperature sensor.

[0029] The communication device 11 is formed in a rectangular or substantially rectangular shape. Specifically, the communication device 11 includes, for example, a tag antenna 11a including a matching circuit and an IC chip 11b. The communication device 11 also includes, for example, a temperature sensor 11c. The IC chip 11b stores unique tag identification information and transmits this information when communicating with the terminal 13. The temperature sensor 11c is, for example, built into the IC chip 11b. The communication device 11 may also be an RFID tag that communicates with the terminal 13 via a reader / writer.

[0030] The communication device 11 is, for example, fixed to the support 21 of the patch body 10 and packaged together with the patch body 10 in a packaging bag 25. Alternatively, the communication device 11 may be attached to the support 21 of the patch body 10 after it has been removed from the packaging bag 25 by the patient.

[0031] The communication device 11 is shielded from electromagnetic waves and unable to communicate when the ointment 22 is protected by the protective film 23 and when it is packaged in the packaging bag 25. The communication device 11 may also be configured to become unable to communicate once the patch body 10 is applied to the patient's skin. Before application to the skin, the communication device 11 is removed from the packaging bag 25 and the protective film 23 is peeled off, releasing the electromagnetic wave shielding and enabling communication. The communication device 11 transmits a second trigger information to the terminal 13 by communicating with the terminal 13. In addition to the second trigger information, the communication device 11 may also transmit information about the patch body 10 on which the communication device 11 is located to the terminal 13.

[0032] In the patch 1 configured in this way, the protective film 23 covering the ointment 22 has a function of shielding electromagnetic waves, so that when the protective film 23 covers the ointment 22 before use, the communication device 11 can be put into a communication-disabled state. Furthermore, when using the patch 10, the communication device 11 can be activated and put into a communication-enabled state by peeling off the protective film 23 from the ointment 22.

[0033] Thus, the patch 1 can disable communication for the communication device 11 before use, and enable communication simply by peeling off the protective film 23, allowing the patient to easily switch the communication state of the communication device 11.

[0034] Furthermore, by attaching the communication device 11 to the support 21 in a detachable manner, the patch 1 can be reused. Therefore, by reusing the communication device 11, the manufacturing cost of the patch 1 can be reduced. Also, for example, if the patient attaches and detaches the communication device 11 to the support, it is possible to provide the communication device 11 to one of the prescribed patches 1, and not provide the communication device 11 to the other patches 1, that is, to prescribe only the patch body 10 as the other patches 1.

[0035] As described above, according to the patch 1 of the embodiment of the present invention, it is possible to disable communication before use and to easily enable communication.

[0036] It should be noted that the present invention is not limited to the embodiments described above. In the examples described above, an example of the adhesive patch 1 was described in which the adhesive patch body 10 has a protective film 23 that shields electromagnetic waves, but the invention is not limited to this.

[0037] For example, as in other embodiments shown in Figures 9 and 10, the adhesive 1 may have a configuration that includes a second protective film 31 as an electromagnetic wave shielding material covering the communication device 11 provided on the support 21. The second protective film 31 is formed in a shape larger than the communication device 11. The second protective film 31 is an electromagnetic wave shielding material formed of, for example, a material having the function of shielding electromagnetic waves.

[0038] For example, the second protective film 31 has shielding properties that block electromagnetic waves. The second protective film 31 covers the communication device 11 and protects it. When the second protective film 31 is protecting the communication device 11, it either blocks electromagnetic waves from the communication device 11 or puts the communication device 11 into a communication-disabled state. For example, when the second protective film 31 is attached to the communication device 11, it puts the communication device 11 into a communication-disabled state, and when it is peeled off from the communication device 11, the communication device 11 is activated and puts the communication device 11 into a communication-enabled state. Such a second protective film 31 is formed from, for example, aluminum foil, metal vapor-deposited film, hydrogel film, etc.

[0039] Thus, when the adhesive patch 1 has a second protective film 31, the first protective film (protective film) 23 protecting the ointment 22 may or may not have shielding properties that block electromagnetic waves. That is, the adhesive patch 1 has a configuration that includes at least one of the first protective film 23 and the second protective film 31, and at least one of the first protective film 23 and the second protective film 31 may have shielding properties that block electromagnetic waves. For this reason, as another example, the adhesive patch 1 may have a first protective film 23 and a second protective film 31, in which the first protective film 23 constitutes an electromagnetic wave shielding material that blocks electromagnetic waves, and the second protective film 31 does not have shielding properties that block electromagnetic waves.

[0040] Furthermore, in the above-described example, the ointment 22 is configured to be the same size as or slightly smaller than the support 21 and larger than the communication device 11. Specifically, the length of the major axis and the minor axis of the ellipse are set to be the same size as or slightly smaller than the length of the long and short sides of the support 21, and the ointment 22 is formed to be larger than the communication device 11. However, the shape of the ointment 22 is not limited to this. For example, as in the patch 1 of other embodiments shown in Figures 11 and 12, the ointment 22 may be configured to be considerably smaller than the support 21 and smaller than the communication device 11.

[0041] As a specific example, the adhesive 22 may be formed in an elliptical shape, with the length of the major axis and the length of the minor axis of the ellipse being half or less of the length of the long side and short side of the support 21, and also smaller than the communication device 11. In such a configuration, a protective film 23 having the same shape as the adhesive 22 would be smaller than the communication device 11, making it difficult to shield electromagnetic waves. Therefore, a second protective film 31 having the shielding properties to block electromagnetic waves as described above should be provided. Another example is that, as shown in Figure 13, the shape of the protective film 23 may be larger than the plaster body 22 and the communication device 11. However, if the protective film 23 is larger than the plaster body 22, a gap may form between the protective film 23 and the support 21, which could cause the communication device 11 to become capable of communication. Therefore, it is preferable that at least the entire circumference of the outer edge of the protective film 23 is in contact with the support 21.

[0042] Furthermore, although the above example described a configuration in which the patch 1 has a packaging bag 25 that shields against electromagnetic waves, it is not limited to this configuration. The patch 1 may have a packaging bag 25 that does not shield against electromagnetic waves, or it may have no packaging bag 25 at all.

[0043] In other words, the present invention is not limited to the embodiments described above, and can be modified in various ways during implementation without departing from its essence. Furthermore, each embodiment may be combined as appropriate, and in that case, the combined effects can be obtained. Moreover, the above embodiments include various inventions, and various inventions can be extracted by selecting combinations from the multiple constituent elements disclosed. For example, if the problem can be solved and effects obtained even if some constituent elements are deleted from all the constituent elements shown in the embodiment, then the configuration with these deleted constituent elements can be extracted as an invention.
