Description of the Related Art Conventionally, when a nurse administers a drug to a patient, the nurse first looks at A) a medication instruction provided by a physician while looking at an instruction screen or a prescription, that is, which patient receives which medication. Based on the indication of whether or not to administer, select and prepare the drug for which the medication is instructed, B) then specify the patient to be administered, and C) further, both the drug and the patient are instructed as instructed. After confirming whether or not the drug had been administered, the drug was administered.

[0003]

However, according to the above-mentioned conventional method used in actual medical practice, medication errors occur one after another, and medical litigation accompanying it is increasing. This largely depends on the confirmation of the nurse who is a person in the above-mentioned stages A), B) and C). Also,
To avoid this mistake, the mental burden on nurses was also great. In addition, the patient's anxiety and fear of medication errors should be eliminated.

[0004] The present invention is intended to solve such a problem, so that medication errors can be reduced as much as possible, the mental burden on nurses can be reduced, and a patient can receive medication with peace of mind. It is intended to provide a simple medication management system.

[0005]

According to a first aspect of the present invention, there is provided a medication management system for assisting a nurse in administering a drug to a patient. The patient identification marker and the medicine identification marker are configured to be readable by the same marker reading means, and the portable terminal equipped with a storage unit for medication instruction data of a medicine to be administered to the patient is provided with the marker When the reading means is attached and the nurse administers the medicine to the patient, the nurse reads the patient identification mark attached to the patient and the medicine identification mark attached to the medicine with a portable terminal equipped with the sign reading means. It is characterized in that a medicine check is performed to determine whether or not the data of the patient and the medicine that have been given coincide with the medicine instruction data stored in the storage means.

[0006] Here, the term "nurse" is used to indicate not only a general nurse but also a staff member who plays a role in administering a drug to a patient at a medical site. Drugs include not only so-called powders, tablets, capsules, liquids, ointments and poultices, but also anything to be administered to a patient in various forms, such as a drug solution to be injected and a drug solution to be instilled.

[0007] The patient identification sign specifies a patient, that is,
A sign for identifying an individual, created individually for a patient ID using a certain code system, and not only the one attached to the patient but also the individual identification means inherent in the human body itself , Fingerprints, voiceprints, irises, etc., in which case there is no need to separately attach an identification mark to the patient.

[0008] The drug identification label refers to a label for specifying a drug, which is individually associated with a drug ID by a certain code system, and includes not only its efficacy and components but also its dosage and administration method. , Which are configured to be distinguishable.

[0009] A portable terminal is a personal digital assistant (PDA), a notebook personal computer, a mobile computer, a PH.

The patient identification marker 1 and the drug identification marker 2 of the present invention
In order to use, it is necessary to register the association with the patient and the drug in advance, and the registration procedure is shown in the flowchart of FIG.

This registration starts with assigning an ID (identification number) to the patient and registering it in the patient information database (S11). This is similar to the ID assignment at the time of creating a medical examination card which is usually performed at the reception of a hospital or the like. When such a medical examination card has already been created for a patient, the patient ID is used. be able to.

Next, an ID is assigned to the medicine and registered in the medicine database (S12). This ID can also be used when a barcode is already attached to the drug. However, when the ID is used for in-hospital medication, not only the drug type information but also the dose unit and Since it is necessary to create an ID including the mode and the like, it may not be possible to simply use the barcode of a commonly attached medicine as it is.

Next, a barcode (patient identification mark 1) is printed according to the patient's ID in the patient information database, and affixed to the patient (S13). Further, it is checked whether the medicine has a barcode and the barcode can be used as it is (S14). If not, the barcode (drug identification mark 2) is printed according to the medicine ID from the medicine database. Then, it is attached to the medicine (S15). O
If it is K, the process ends (S16).

When the patient identification marker 1 and the medicine identification marker 2 are prepared in this way, the medication can be managed as outlined in FIGS. 1 and 2; however, the flow chart of FIG. This procedure will be described in more detail with reference to a diagram showing an example of a medication confirmation screen in the nurse mode and a diagram showing an example of a medication confirmation screen in the patient mode in FIG.

For medication management, first, as shown in FIG. 2C, a doctor needs to input a medication instruction (S21). Then, this data is sent from the distributed processing terminal 5 that has received the input to the central processing unit 7 and registered in the medication instruction database DT (S22), and then the medication instruction data is transmitted to all the distributed processing terminals 5. Or
The data can be referenced from the terminal 5 and the data is distributed (S2
3, FIG. 2 (d)). The data is taken into the portable terminal 4 (S24), and the nurse N selects and prepares the medicine F while watching the display on the portable terminal 4 (S24).
25, FIG. 2 (e)).

The nurse N having prepared the medicine in this way goes to the sickroom and first puts on the portable terminal 4 equipped with the sign reading means 3.
When the patient identification mark 1 is read (S26), the terminal device 4 checks whether or not the medicated instruction data stored and stored includes the read patient data (S27). An error warning is issued (S28),
The reading of the patient identification mark again, that is, the reading of the patient identification mark of the correct patient is prompted.

If there is patient data, the nurse N causes the portable terminal 4 to read the medicine identification mark 2 (S2).
9) The terminal 4 checks whether or not the medicated instruction data stored and stored includes the read medicine data (S3).
0) If there is no medicine data, a warning of a medicine error is generated (S31), and the reading of the medicine identification mark again, that is, the preparation of the correct medicine is prompted.

If the medicine data match, a medication confirmation is displayed (S32), and in response, a medication check is performed to confirm the medication. FIG. 9 shows the display screen (display unit) 4a of the portable terminal 4 at this time.
In this figure, it can be seen that the patient has been confirmed and one kind of medicine has been confirmed.

Further, on this screen, it is possible to confirm a treatment other than the medication performed by the nurse on the patient, such as "temperature measurement". For these treatments, it is difficult to attach a treatment identification mark to the treatment itself and have the sign reading means 3 read the treatment. For example, a list of treatment identification signs is prepared, and Then, the treatment identification mark can be read for the treated one, and the treatment can be confirmed.

Next, although not described with reference to FIGS.
A similar medication confirmation can be given to the patient, which is called a patient mode medication confirmation, as opposed to the nurse mode medication confirmation described above, and inserted before the final medication as needed. (S33). FIG. 10 shows a display screen (display section) 4a displaying the patient confirmation screen at this time.

On this screen, in addition to the name of the medicine, a photo such as a PTP (press-through pack) containing the medicine and the like are displayed as remarks so that the patient can confirm the given medicine. I have. Looking at this, the patient
It is possible to confirm that the medicine is for oneself, that there is no mistake in the medicine, and that the medicine is effective, and that the medicine can be safely received.
Further, at the time of this confirmation, the medication confirmation information can be output as a voice through a speaker 4f provided in the portable terminal device 4, and even if the patient is a visually impaired person, the medication confirmation in the patient mode can be performed. can do.

Here, as the items to be displayed for confirming the medicine, the shape of the medicine (powder, tablet, liquid, etc.), the color, the shape and color of the medicine container or packaging, etc. may be used.

In this way, after the patient is confirmed or not, the medicine is administered (S34), and when that is input to the portable terminal 4, it is recorded as medication processing data (S35). When the terminal device 4 is placed on the information exchange table (cradle) 41, the medication processing data is registered and updated in the medication instruction database DT and the medication management database DU of the central processing unit 7.

FIGS. 11A to 11F are diagrams showing various bar codes used in the present invention.

As described above, the barcode used as an example of the patient identification mark or the medicine identification mark in the present invention includes:
There are one-dimensional barcodes and two-dimensional codes, and FIGS. 11A and 11B show one-dimensional barcodes (c) and (b).
(D), (e), and (f) are examples of two-dimensional barcodes.

FIG. 11A shows a JAN code, which is the most familiar code system used internationally as a common product code. FIG. 11B is called an ITF code, which is used as a JIS standard physical distribution symbol for identifying the contents of a package. There are many other one-dimensional barcode types.

As described above, there are many types of one-dimensional barcodes, but some of these one-dimensional barcodes can be read by the same marker reading means in a distinguishable manner. One of the bar codes is attached to the medicine, and the other is attached to the patient.

In this case, not only can the same sign reading means read both, but also the mode can be changed so that the reading side can determine whether the identification sign to be read is for a patient or for a medicine. Instead of strictly determining the reading order, for example, a medicine, a patient, and a medicine can be read in this order. Further, since the codes happen to be the same, a reading error does not occur, and errors can be avoided more reliably.

FIG. 11C shows a so-called QR (Quick Response) Code Model 2, which is a two-dimensional code born in Japan that emphasizes high-speed reading, and FIG. 11D shows a two-dimensional code called PDF417 that can handle a large capacity. The code can be read by a one-dimensional barcode scanner (marker reading means). FIG. 11E shows a two-dimensional code called Maxi Code, which is readable at high speed and 360 degrees.
(F) is a two-dimensional code called Veri Code assumed for relatively small parts having high error correction capability.

There are many types of two-dimensional codes other than the above, and the two-dimensional codes can be used in the medication management system of the present invention according to the suitability of each two-dimensional code. In particular, since the two-dimensional code can be miniaturized, it is suitable for attaching a small number of drugs.

FIGS. 12A and 12B show an example of the patient identification means used in the present invention. FIG. 12A is a perspective view of the appearance, FIG. 12B is a view showing an example of its use, and FIG. (A) is an external perspective view of the identification means.
(B) is a diagram showing an example of its use.

A method of attaching a separately created patient identification mark to a patient to identify a patient has been described above. However, a patient, which is a human body, can identify and identify the individual in the first place. If a sign is provided and a patient identification means for identifying a patient can be used with the identification sign, it is not necessary to separately attach a patient identification sign.
The patient identification means 8 in FIG. 12A is a card-type fingerprint recognition identification means used by being inserted into a card adapter (not shown) of a portable terminal 4B composed of a notebook personal computer or the like. The main body 8b includes a card section 8a inserted into the main body 8b, and a scanner section 8c formed in a concave shape according to the shape of the fingertip provided on the main body section 8b.

As shown in FIG. 12 (b), when this identification means 8 is inserted into the card adapter of the portable terminal 4B, the left index finger of the patient is placed on the scanner section 8c, and a predetermined identification procedure is executed. Patients can be identified.

The patient identification means 9 shown in FIG. 13 is an identification means 9 for recognizing a human iris used by being connected to the distributed processing terminal 5 constituted by a personal computer or the like.

In the present invention, such patient identification means 8,
9 can be used as a substitute for the patient identification marker. In this case, it is necessary to provide the patient identification devices 8 and 9 separately from the marker reading device 3 for reading the medicine identification marker. However, there is a point to be solved in terms of cost increase. However, depending on the progress of image analysis,
It is anticipated that the same identification means will enable the individual identification of the human body and the reading and identification of the drug identification mark, in which case, if such identification means are incorporated into the medication management system of the present invention, The convenience and usefulness of the present invention are further improved.
