Description

  The present invention relates to a medication management method and a medication management system comprising a first portable device that can be carried by a patient, a second portable device carried by a person in charge of medication, and a management device.

Conventionally, the patient's personal information is printed on the bracelet with a barcode, and the corresponding information transmitted from the management computer based on the personal information obtained by reading the barcode at the time of medication and the fingerprint information collected from the fingerprint, An example of a system in which a patient can be identified by collating with a portable terminal for patient identification and the contents of medication can be confirmed is disclosed (for example, see Patent Document 1).
JP 2003-67488 A

However, in order to store the fingerprint information in the management computer in advance when identifying the patient, it is necessary to collect and store the fingerprint information, which takes time and effort.
Moreover, even if patient identification and confirmation of medication content are appropriate, there is a possibility that the prescribed drug and the drug to be administered do not match.

  The present invention has been made in view of these points, and reduces the labor and time required for information recording as compared with the prior art, and makes it possible to clarify whether or not medication to a patient is appropriate. The purpose is to provide a management system.

(1) Means for solving a problem (hereinafter, simply referred to as “solution means”) 1 includes both person-in-charge information for specifying a person in charge of medication to be administered to a patient and patient information for specifying the patient. A first portable device that can be carried by a patient, comprising a first storage means for storing and a first display means for displaying the patient information; a second storage means for storing both the patient information and the person-in-charge information; and A second portable device carried by the medication person in charge having a second display means for displaying the person-in-charge information; and storing both the patient information and the person-in-charge information in the third storage means, and a reader and information reading means And a management device having at least one communication between the first storage means, the second storage means, and the third storage means by communication that is possible only within a predetermined distance based on the information stored in the third storage means. Authenticate with When the authentication is performed between one or more of the mutual authentication step and the mutual authentication step, a setting step for enabling the information acquisition by the reader is possible, and the information can be acquired by the reader in the setting step. If it is set to, the acquisition process which acquires both the patient information displayed on the said 1st display means and the person in charge information displayed on the said 2nd display means with the said reader, It transmits from the said management apparatus. The information displayed on the information display means based on the display signal, and when the medication reading information related to the medicine prescribed by the doctor to the patient is read by the information reading means, together with the patient information and the person-in-charge information obtained in the obtaining step Based on whether or not the patient information, the person-in-charge information, and the medication information stored in advance in association with the third storage means match, the approval or disapproval of medication is reported. And summarized in that and a notification step of.

  The “patient” is generally a human being, but in the case of an animal hospital or the like, it is an animal. “Patient information” is described by characters, symbols, codes (including barcodes), etc., and is realized by, for example, a unique number assigned to each patient, a patient's name, sex, age, and the like. “Medication person in charge” is a person who has the qualification to administer medication to a patient, and corresponds to, for example, a doctor, a nurse, a pharmacist or the like. “Person information” is described by characters, symbols, codes (including barcodes), etc., and is realized by, for example, a unique number assigned to each person in charge of medication, the name, sex, age, etc. of the person in charge of medication. As the “first portable device”, any device that can be carried by a patient and capable of wireless communication can be applied. For example, a wireless IC tag (including an RFID tag), a microchip, or the like is applicable. As the “second portable device”, any device can be applied as long as it can be carried by a person in charge of medication and can communicate regardless of wired / wireless. For example, an IC card (including an ID card), a wireless IC tag, a mobile phone, a mobile phone An information terminal (PDA; Personal Digital Assistant) or the like is applicable. The “doctor” varies depending on the treatment target, and includes a dentist, a veterinarian and the like in addition to a normal doctor. “Dose information” includes administration information (eg, dosage, administration time, etc.) and drug information described later, and includes information recorded in medical records, prescriptions, and the like. This medication information is described by information exchange codes (hereinafter referred to as “characters”) such as letters, symbols (including codes), codes (including barcodes, QR codes, etc.), etc. Physical deformation was applied to the object such as recording (including storage and printing) and display on a portable device or a second portable device, display on a display device, unevenness (including printing), notches, perforations, etc. Realized by recording. A device that can manage various types of information can be applied to the “management device”, for example, a server or a terminal connected to be communicable with the server. As the “information display means”, any device can be applied as long as it can display medication information. For example, a display device is applicable. The reader and the information reading means may be the same device or different devices depending on the acquisition target.

  According to the solution 1, the first portable device can be carried by the patient, and the second portable device is carried by the person in charge of medication. Note that the first portable device may be carried by the patient himself / herself or by a person related to the patient (for example, a parent, a child, a relative, etc.). The management device is not limited to the case where the person in charge of the medication is carried, but includes a case where it is disposed in the treatment bed or in the vicinity thereof, a case where it is installed in a predetermined building or room (for example, a management room), and the like. Authentication is performed between each of the first portable device, the second portable device, and the management device (mutual authentication; mutual authentication process), and information is acquired by the reader only when one or more mutual authentications are performed. The patient information and the person-in-charge information are acquired by the reader that can be acquired (setting process), and the acquired patient information and the person-in-charge information and the medication information read by the information reading means are acquired. Based on this, the approval or disapproval of the medication is notified (notification process). Since patient information and person-in-charge information can be specified by characters or the like, labor and time required for information recording can be reduced as compared with the conventional case. In addition, mutual authentication is performed between devices located within a predetermined distance, and the patient information and person-in-charge information acquisition (reader) and the medication information reading (information reading means) are performed in separate procedures. Since the permission or non-permission is notified, it is clear whether the medication to the patient is appropriate.

(2) Solving means 2 is a medication management method described in solving means 1, and in the notification step, drug information that is information acquired by a reader or information reading means and specifies a drug to be administered to a patient is medication information. The gist is to notify the approval of medication only when the medication information contained in the drug is consistent and the medication conditions relating to the dosage, administration time, etc. are satisfied.

  According to Solution 2, not only the prescribed drug and the drug to be administered match, but also dosing is allowed only after meeting the dosing conditions for determining whether the dosage, administration time, etc. are appropriate To make a notification. Therefore, medication errors can be prevented in advance.

(3) The solving means 3 is a medication management system, which can be carried by a patient, and includes both patient information for identifying the patient and personnel information for identifying a medication specialist who administers the patient. A first storage means for storing; a first display means for displaying the patient information; a first communication means for individually performing wireless communication with respect to a second portable device and a management device located within a predetermined distance; Either authentication or non-authentication is determined based on whether or not the person-in-charge information acquired from the second portable device or the management device through one communication means matches the person-in-charge information stored in the first storage means. A first portable device having a first authentication means; a second storage means carried by the person in charge of medication, storing both the patient information and the person in charge information; and a second in which the person in charge information is displayed. Display means; A second communication means for individually communicating the portable device and the management device; patient information acquired from the first portable device or the management device through the second communication means; and a patient stored in the second storage means Based on a second portable device having a second authentication means for determining whether authentication or non-authentication is performed depending on whether or not the information matches, and a display signal transmitted from the management device, a doctor is attached to the patient. Information display means for displaying medication information related to the prescribed medicine, third storage means for storing the patient information, the person-in-charge information, and the medication information in association with each other, the first portable device, and the second portable device Third communication means for performing individual communication, patient information acquired from the first portable device through the third communication means, or person-in-charge information acquired from the second portable device is 3rd authentication means for determining whether authentication or non-authentication is made depending on whether or not it matches the patient information or the person-in-charge information stored in the storage means; the first authentication means; the second authentication means; When at least one of the three authentication means determines authentication, the information is set to be able to be acquired by the reader, and the patient information displayed on the first display means and the person-in-charge information displayed on the second display means Information acquisition means for acquiring both by the reader, information reading means for reading the medication information displayed on the information display means, patient information and person-in-charge information acquired by the information acquisition means, and the information reading means Information notifying whether or not medication is permitted based on whether the medication information matches the patient information, the person-in-charge information, and the medication information stored in the third storage means. The gist of the present invention is that it comprises a management device having knowledge means.

  The person who should carry each of the first portable device and the second portable device, the position where the management device is carried or installed, and the like are the same as those of Solution 1 described above. Authentication / non-authentication is determined by a device located within a predetermined distance range in the first portable device, the second portable device, and the management device, and when authentication is determined by one or more, information can be acquired by a reader To do. The information acquisition unit acquires both the patient information and the person-in-charge information using the reader that can be acquired, and reads the medication information by the information reading unit. Based on whether or not the patient information, the person-in-charge information, and the medication information match each information stored in association with the third storage device, the notification device notifies the approval or disapproval of the medication. Since patient information and person-in-charge information can be specified by characters or the like, labor and time required for information recording can be reduced as compared with the conventional case. In addition, since acquisition of patient information and person-in-charge information and reading of medication information are performed in separate procedures, the approval or disapproval of medication is notified, so it becomes clear whether or not medication to the patient is appropriate.

(4) Solving means 4 is the medication management system described in solving means 3, and is provided in the first portable device, and when the first authenticating means determines authentication, it is acquired by the managing device through the first communication means. A first transmission unit configured to transmit a permission signal; and a second transmission unit which is provided in the second portable device and transmits an acquisition permission signal to the management device through the second communication unit when the second authentication unit determines authentication. And the information acquisition means is configured to enable acquisition of information by a reader when receiving an acquisition permission signal transmitted from one or both of the first transmission means and the second transmission means. And

  According to the solution means 4, since the management apparatus can grasp the authentication of the first portable apparatus or the second portable apparatus from the acquisition permission signal received through the information acquisition means, the management apparatus is set to enable the information acquisition by the reader. In other words, authentication is performed between one or more of the first portable device and the second portable device, between the second portable device and the management device, or between the first portable device and the management device. Unless it becomes clear by the acquisition permission signal, the reader cannot be used. Therefore, it is possible to prevent patient information and person-in-charge information from being acquired by the reader in an unauthenticated state.

(5) The solution means 5 is the medication management system described in the solution means 3 or 4, and the notification means is information acquired by the reader or the information reading means, and drug information specifying the medicine to be administered to the patient is provided. The gist is to notify the permission of medication only when the medication information included in the medication information is matched and the medication conditions regarding time, amount, etc. are satisfied.

  According to the solution means 5, like the solution means 2 described above, a notification is given to permit medication only after satisfying the medication conditions. Therefore, medication errors can be prevented in advance.

(6) The solving means 6 is the medication management system described in any one of the solving means 3 to 5, and the notifying means includes patient information and person-in-charge information acquired by the information acquiring means, and information reading means. The gist is to notify part or all of the information about the read medication information.

  According to the solution 6, since part or all of the patient information, the person-in-charge information, and the medication information is notified, the person in charge of medication can confirm the prescribed medicine and the medicine to be administered. Therefore, medication errors can be prevented in advance.

  According to the present invention, since patient information and person-in-charge information can be specified by characters or the like, labor and time required for information recording can be reduced as compared with the conventional case. In addition, mutual authentication is performed between devices located within a predetermined distance, and acquisition of patient information and person-in-charge information and reading of medication information are performed in separate procedures, and notification of approval or disapproval of medication is made. It becomes clear whether or not the medication to the patient is appropriate.

  The best mode for carrying out the present invention will be described with reference to the drawings.

[Embodiment 1]
The first embodiment is an example in which authentication is performed only between the second portable device and the management device, and will be described with reference to FIGS. FIG. 1 is a block diagram schematically showing a configuration example of a medication management system. FIG. 2 shows a configuration example of each information. FIG. 3 shows an actual usage example. FIG. 4 is a chart showing an example of a medication procedure for a patient. In this example, “doctor” is the person in charge of medication.

  The medication management system shown in FIG. 1 includes a first portable device 10, a second portable device 20, a management device 30, and information display means 40. The first portable device 10 is, for example, a wristband with a built-in wireless IC tag, and can be carried by a patient. That is, the patient himself / herself may carry it, or a person related to the patient (for example, a parent, a child, a relative, an agent, etc.) may carry it. The second portable device 20 is, for example, an ID card that also serves as a name tag, and is carried by a doctor. The management apparatus 30 in this example includes a non-portable server 30b installed in a management room or the like as illustrated by a two-dot chain line, and a portable terminal 30a that can communicate with the server 30b. . In this example, the information display means 40 is a television (display) provided in a treatment bed such as a hospital.

  The first portable device 10 includes first display means 14 and the like. The first display means 14 is, for example, a barcode displayed on the surface of the wristband by printing or pasting, and the information recorded as the barcode includes at least patient information J1 for identifying the patient. This patient information J1 is an identification number unique to each patient and can be automatically generated, and is composed of alphanumeric characters such as “K012345” shown in FIG.

  The second portable device 20 includes a second communication unit 21, a second storage unit 22, a second authentication unit 23, a second transmission unit 24, a second display unit 25, and the like. The second communication means 21, the second authentication means 23, and the second transmission means 24 are each realized by software or hardware.

  The second storage means 22 stores both the above-described patient information J1 and person-in-charge information J2 for specifying a doctor or the like in characters or the like. This person-in-charge information J2 is an identification number unique to each person in charge of medication and can be automatically generated. In the example of a doctor, the person-in-charge information J2 is composed of alphanumeric characters such as “D001234” shown in FIG. The second display means 25 is, for example, a barcode displayed on the surface of the name tag by printing or sticking, and the information recorded as the barcode includes at least person-in-charge information J2. The second communication means 21 communicates with the management device 30. The second authentication means 23 performs authentication or non-authentication depending on whether or not the patient information J1 acquired from the management device 30 through the second communication means 21 and the patient information J1 stored in the second storage means 22 match. Decide either. When the second authentication unit 23 determines authentication, the second transmission unit 24 transmits an acquisition permission signal I2 to the management apparatus 30 through the second communication unit 21.

  The management device 30 includes a third communication unit 31, a third authentication unit 32, a reader 33, an information acquisition unit 34, an information reading unit 35, an information output unit 36, a notification unit 37, a third storage unit 38, and the like. How these elements are allocated is arbitrary, but in this example, the server 30b has the information output means 36 and the third storage means 38, and the terminal 30a has the other elements. The third communication unit 31, the third authentication unit 32, the information acquisition unit 34, the information reading unit 35, and the notification unit 37 are each realized by software or hardware.

  The third storage means 38 stores patient information J1, person-in-charge information J2, and medication information J3 in association with each patient. The medication information J3 is information related to the medicine prescribed by the doctor to the patient, and corresponds to medication information J4 consisting of alphanumeric characters such as “AB00012” and “CD24680” shown in FIG. The medication information J3 may include quantity information J5 representing the quantity per time, time information J6 representing the date of administration (or taking), etc., as necessary.

  An example of storing the patient information J1, the person-in-charge information J2, and the medication information J3 in association with each other is shown in FIG. In this example, in correspondence with each patient (patient information J1), doctors, nurses and the like (person-in-charge information J2) and information related to medication (medicine information J3) are associated and stored as the association table 38a. The association table 38a of this example shows the person-in-charge information J2 (medication person in charge) and the medicine information J3 (drug information) for each patient in which “K012345”, “K012346”, “K112233”, etc. are given to the patient information J1 (patient). ). The person-in-charge information J2 may store not only the identification number of the doctor in charge but also the identification number of the nurse and the identification number of the pharmacist. As described above, the medication information J3 may be associated with the quantity information J5 and the time information J6.

  The third communication unit 31 communicates with the second portable device 20. In the case where mutual authentication is performed with the second portable device 20 using wireless signals, it is desirable that the second portable device 20 be limited to a predetermined distance range (for example, 3 meters or 5 meters). The third authentication means 32 performs authentication or non-dependence depending on whether or not the person-in-charge information J2 acquired from the second portable device 20 through the third communication means 31 matches the person-in-charge information J2 stored in the third storage means 38. Determine one of the authentication. When the authentication is determined by the second authentication unit 23 and the third authentication unit 32, the information acquisition unit 34 sets the reader 33 so that the information can be acquired, and the patient information J1 displayed on the first display unit 14 and the first information are displayed. 2 The reader 33 acquires both the person-in-charge information J2 displayed on the display means 25. In this example, a barcode reader is used as the reader 33. The authentication / non-authentication by the second authentication means 23 can be determined by whether or not the acquisition permission signal I2 is transmitted from the second portable device 20.

  The information reading unit 35 reads the medication information J3 displayed on the information display unit 40. For example, when the medication information J3 is displayed on the information display means 40 with a QR code, the information reading means 35 is a QR code reader or an image recognition means (that is, a means for recognizing the QR code image and converting it into information such as characters). Etc. The information output means 36 outputs the medication information signal I3 and the information erasure signal I4 to the information display means 40, and displays the medication information J3 stored in the third storage means 38 and corresponding to the patient to be administered. . The notification means 37 includes patient information J1 and person-in-charge information J2 in which the patient information J1 and person-in-charge information J2 acquired by the information acquisition means 34 and the medication information J3 read by the information reading means 35 are stored in the third storage means 38. And whether or not the medication is permitted is notified based on whether or not it matches the medication information J3. This notification means 37 may be notified visually by display on a display (for example, a liquid crystal display) or a light emitter (for example, LED), or an audible notification by sound (sound, music, sound effect, etc.). Alternatively, tactile notification may be performed by vibrating a vibrating body (for example, a vibrator).

  FIG. 3 shows an actual application example of the medication management system configured as described above, and FIG. 4 shows an example of a medication procedure for a patient. First, in FIG. 3, a television (information display means 40) for displaying medication information J3 (in this example, a QR code) according to a signal transmitted from a server 30b installed in a management room or the like is provided in the treatment bed. The patient K sleeping in the treatment bed carries the wristband (first portable device 10) while wearing it on the wrist or the like. In the wristband, patient information J1 for specifying the patient K is represented by a barcode (first display means 14). The doctor D who visited during the round visits the ID card (second portable device 20), which also serves as a name tag, on the clothes (for example, white robe) and carries it, and also carries the terminal 30a. In the name tag, person-in-charge information J2 for specifying the doctor D is represented by a barcode (second display means 25).

  In the chart shown in FIG. 4, time advances from the upper side to the lower side of the drawing (the same applies to FIGS. 6 and 8 described later). At time t10, the mutual authentication signal M2 is transmitted and received between the second portable device 20 and the terminal 30a to perform mutual authentication (corresponding to a mutual authentication step; step S10). When the second authentication unit 23 determines authentication (YES in step S11a), the second portable device 20 transmits an acquisition permission signal I2 through the second communication unit 21 at time t11 (step S13). However, if the second authentication means 23 determines non-authentication (NO in step S11a), the second portable device 20 does nothing (step S12a).

  Similarly, when the third authentication unit 32 determines authentication (YES in step S11b) and receives the acquisition permission signal I2 from the second portable device 20, the terminal 30a sets the reader 33 to be able to acquire information. (Corresponding to the setting step; step S14). In parallel with this setting, it is desirable to turn on the LED or the like provided in the second portable device 20 to notify the medication person in charge that the setting is made possible. On the other hand, when the third authenticating means 32 determines non-authentication (NO in step S11b), the terminal 30a does nothing (step S12b).

  After the information acquisition by the reader 33 is set, the information acquisition means 34 is the patient information J1 displayed as a barcode on the first display means 14 and the person-in-charge information displayed on the second display means 25 as a barcode. Both of J2 and J2 are acquired by the reader 33 (corresponding to an acquisition process; step S15). In this example, it is desirable that a doctor or the like carrying the terminal 30a obtains the patient information J1 and the person-in-charge information J2 using the reader 33.

  The server 30b transmits the medication information signal I3 to the information display means 40 at time t12 (step S16), and transmits the information deletion signal I4 to the information display means 40 at time t13 (step S18). Therefore, the medication information J3, which is the content of the medication information signal I3, is displayed on the information display means 40 from time t12 to time t13. Thus, the medication information J3 displayed on the information display means 40 with the QR code is read by the information reading means 35 (step S17). This reading is preferably performed by a doctor or the like as in step S15 described above.

The patient information J1 and person-in-charge information J2 acquired in step S15 and the medication information J3 read in step S17 coincide with the patient information J1, the person-in-charge information J2, and the medication information J3 stored in the third storage means 38. Based on whether or not to do so, the notifying means 37 notifies permission or disapproval of medication (corresponding to a notification step; step S19).
In performing the notification, not only permission / denial of medication, but also part of the information about the patient information J1 and the person-in-charge information J2 acquired by the information acquisition unit 34 or the medication information J3 read by the information reading unit 35 Or it is desirable to notify all. In addition, the medicine information J4 acquired by the reader 33 or the information reading means 35 matches the medicine information included in the medication information J3 and the medication permission is notified only when the medication conditions relating to the amount, the administration time, etc. are satisfied. Also good.

According to Embodiment 1 described above, the following effects can be obtained.
(1) Mutual authentication is performed between the second portable device 20 and the terminal 30a located within a predetermined distance (mutual authentication step; step S10 in FIG. 4), and the reader 33 can obtain information. Then, the patient information J1 and the person-in-charge information J2 are acquired by the reader 33 (acquisition step; step S15 in FIG. 4), and the patient information J1, the person-in-charge information J2, and the information reading means 35 are acquired. Based on the medication information J3 read by the above, the approval or disapproval of medication is notified (notification process; step S19 in FIG. 4). The patient information J1 and the person-in-charge information J2 can be specified by characters or the like, can be automatically generated, and can reduce the labor and time required for information recording as compared with the prior art. In addition, mutual authentication is performed between devices located within a predetermined distance, and acquisition of patient information J1 and person-in-charge information J2 and reading of medication information J3 are performed in separate procedures, and permission or disapproval of medication is performed. Since it notifies, it becomes clear whether the medication to a patient is appropriate.

(2) The notifying unit 37 notifies the permission of medication only when the medication information J4 matches the medication information included in the medication information J3 and the medication conditions regarding the quantity, administration time, etc. are satisfied (step S19 in FIG. 4). ). Not only do the prescription medicines and the medicines to be administered match, but a notification is given to permit the medication only after satisfying the medication conditions for determining whether the dosage, administration time, etc. are appropriate. Therefore, medication errors can be prevented in advance.

(3) The reader / writer 33 is configured not to be used unless the authentication / non-authentication determined by the second authentication means 23 of the second portable device 20 is revealed by the acquisition permission signal I2 (steps S13 and S14 in FIG. 4). ). Therefore, it is possible to prevent the patient information J1 and the person-in-charge information J2 from being acquired by the reader 33 in the non-mutual authentication state.

(4) Since some or all of the patient information J1, the person in charge information J2, and the medication information J3 are notified (step S19 in FIG. 4), the doctor as the person in charge of medication is the prescribed medicine and the medicine to be administered. And can be confirmed. Therefore, it is possible to prevent medication errors by checking the notified medicine.

[Embodiment 2]
The second embodiment is an example in which mutual authentication is performed between the first portable device 10 and the terminal 30a in addition to the mutual authentication performed between the second portable device 20 and the terminal 30a in the first embodiment. Therefore, description will be given with reference to FIGS. Note that the configuration and the like of the medication management system are the same as those in the first embodiment, and in the second embodiment, points different from the first embodiment will be described in order to simplify the illustration and description. Therefore, the same elements as those used in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.

  In FIG. 5, a first storage unit 11, a first authentication unit 12, a first transmission unit 13 and a first communication unit 15 are added to the first portable device 10. The first storage unit 11 stores both the patient information J1 and the person-in-charge information J2 in characters or the like. The first communication means 15 performs wireless communication individually for the second portable device 20 and the terminal 30a located within a predetermined distance. The first authentication unit 12 determines whether the person-in-charge information J2 acquired from the second portable device 20 or the terminal 30a through the first communication unit 15 matches the person-in-charge information J2 stored in the first storage unit 11. Depending on whether or not, either authentication or non-authentication is determined.

  In the second portable device 20, functions are added to the second communication unit 21 and the second authentication unit 23. That is, the second communication means 21 communicates not only with the terminal 30 a but also with the first portable device 10. The second authentication means 23 includes not only the case where the patient information J1 is acquired from the terminal 30a but also the case where the patient information J1 is acquired from the first portable device 10.

  In the terminal 30a, functions are added to the third communication unit 31 and the third authentication unit 32. That is, the third communication unit 31 communicates not only with the terminal 30 a but also with the first portable device 10. The third authenticating means 32 is either authenticated or non-authenticated based on one or both of matching / mismatching of the patient information J1 and matching / mismatching of the person-in-charge information J2, depending on the object to be mutually authenticated. To decide.

  FIG. 6 shows an example of a medication procedure for a patient regarding the medication management system configured as described above. The chart shown in FIG. 6 is different from the chart shown in FIG. 4 in the following two points. The first point is that mutual authentication is performed by transmitting and receiving the mutual authentication signal M1 between the first portable device 10 and the terminal 30a (steps S20, S21a, S21b, S22a, S22b, and S23 described later are performed). reference). The second point is a condition for enabling the reader 33 to obtain information (see step S24 described later).

  In FIG. 6, at time t20, the mutual authentication signal M1 is transmitted and received between the first portable device 10 and the terminal 30a to perform mutual authentication (corresponding to a mutual authentication step; step S20). If the 1st authentication means 12 determines authentication (it is YES at step S21a), the 1st portable apparatus 10 will transmit the acquisition permission signal I1 through the 1st communication means 15 at the time t21 (step S23). On the other hand, when the first authentication means 12 determines non-authentication (NO in step S21a), the first portable device 10 does nothing (step S22a).

  On the other hand, in the terminal device 30a, the third authentication means 32 determines authentication (YES in step S21b), receives the acquisition permission signal I2 from the second portable device 20 at time t11, and from the first portable device 10 at time t21.

Instead of this form, the information may be read from the information display means 40 made of another medium. As another medium, for example, a medication number display means such as a medical ticket or a medical record is applicable. Since only the medium of the information display means 40 is different, the same effect as in the first to third embodiments can be obtained.

(7) In the first to third embodiments, the medication information J3 is read from the television (information display means 40) using the information reading means 35, and the medication information J3 read is stored in the third storage means 38. Based on whether or not it coincides with J3, the notification means 37 notifies the permission or non-permission of medication (see steps S17 and S19 in FIGS. 3 and 4). Instead of this form, the information reading means 35 is used to read the medicine information recorded in advance in the medicine itself or the medicine packaging container, and whether the read medicine information matches the medicine information included in the medication information J3. Based on the above, the notification means 37 may notify the permission or non-permission of medication.

  According to this configuration, the drug information recorded in the medicine itself (for example, the surface of a tablet or capsule) or the medicine packaging container (for example, a medicine package, a medicine bag, a medicine container, etc.) is an information source for accurately identifying the medicine. is there. The drug information is read by the information reading means 35, and the notification means 37 notifies the permission of medication only when the medicine to be administered (drug information) matches the prescribed medicine (medication information). Therefore, a medication error can be prevented more reliably.

(8) Patient biological information is added to the patient information J1 and stored in the third storage means 38, and the biological information acquired from the patient by the reader 33 or the information reading means 35 is stored in the third storage means 38 as patient information J1. The notification unit 37 may notify permission or disapproval of medication based on whether or not the biometric information matches. “Biological information” is information that can identify a patient, and includes information such as a fingerprint, a palm, a retina, an iris, a blood vessel, a voice, and DNA.

  According to this configuration, it is determined whether or not the biometric information acquired from the patient matches the biometric information stored in the third storage unit 38, that is, whether or not the patient is to be dispensed, and whether or not the medication is permitted. Inform. Therefore, a medication error can be prevented more reliably.
