Patient barcodes showing the kinds and doses of the pharmaceuticals to be medicated are affixed on the clinical chart when the pharmacist prepares the pharmaceuticals, the barcodes provided on a receptacle or a package of the pharmaceuticals are read by a barcode reader and contents are compared by accessing a database in a server by a second terminal equipment. Furthermore, a patient barcode provided in the vicinity of a bed of an inpatient is read by a portable terminal equipment; the patient barcodes are compared to be judged whether the patients coincide or not.
TECHNICAL FIELD The present invention relates to a medication system and a medication method for medicating pharmaceuticals to patients in a medical field such as a hospital by which erroneous medication can be prevented.
BACKGROUND ART When pharmaceuticals are medicated to patients in a hospital or in a pharmacy, a pharmacist or a nurse (hereinafter, called �medical attendant�) mixes pharmaceuticals or takes out predetermined kinds and numbers of merchandized pharmaceuticals from a cabinet by following a prescription or a clinical chart of a doctor, and the packed pharmaceuticals are given to patients. Alternatively, the pharmaceuticals are medicated to inpatients by injection or instillation at a predetermined time interval.
DISCLOSURE OF INVENTION The present invention is objected to solve the above-mentioned problems of the prior art, and to provide a medication system and a medication method of the pharmaceuticals in which it is possible to check whether the kind and the dose of the pharmaceuticals are followed the prescription or the clinical chart or not, whether the pharmaceuticals and the patient to be medicated coincide with those of the prescription or the clinical chart or not when the pharmaceuticals is medicated to the patient. Furthermore, the present invention is objected to provide a medication system and a medication method of the pharmaceuticals in which the pharmaceuticals never be combined and the dose of the pharmaceuticals can be checked when the doctor describes the prescription or the clinical chart.
BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a block diagram for showing a configuration of a medication system of pharmaceuticals in an embodiment of the present invention;
BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a medication system and a medication method of pharmaceuticals in accordance with the present invention is described. A block configuration of the medication system in the embodiment is shown in FIG. 1.
When a doctor examines a patient and decides kinds and doses of pharmaceuticals which are effective to remedy the patient, he inputs the name of the patient, names of the pharmaceuticals and the doses of the pharmaceuticals, and so on through the key board 22. When the names of the pharmaceuticals and so on are inputted, the first terminal equipment 20 accesses information with respect to the pharmaceuticals (hereinafter, it is called �database�) which is memorized in the server 10 through the network 15, and reads codes corresponding to the kinds and medication doses of the inputted pharmaceuticals from the database. The codes read from the database are printed as distinguishing marks such as barcodes by the printer 21 (hereinafter, the distinguishing mark is called �barcode�). The barcodes 2 are affixed on a prescription or clinical chart 1. A patient barcode �A� is similarly printed by the printer 21 and affixed on the prescription or clinical chart 1. These operations can be operated by another medical attendant by following the instruction of the doctor.
When the prescription or clinical chart 1 is carried to a nurse room, a medical attendant reads the barcodes 2 and the patient barcode �A� affixed on the prescription or clinical chart 1 by using the barcode reader 31. The second terminal equipment 30 accesses the database in the server 10 with using information of the barcodes 2 and the patient barcode �A�, and reads the kinds and doses of the pharmaceuticals indicated by the barcodes 2 from the server 10. The data read from the server 10 is memorized in an internal memory and displays on the monitor display 32. The intended use of the patient barcode �A� will be described below.
When the kinds and the doses of the pharmaceuticals coincide with those described on the prescription or clinical chart 1, the medical attendant carries the prepared pharmaceuticals, for example, to an inpatient 7, and the pharmaceuticals will be medicated to the inpatient 7. Thus, the third terminal equipment 40 is connected to the second terminal equipment 30 for memorizing the contents such as the patient barcode �A� affixed on the prescription or clinical chart 1 for identifying the patient read by the barcode reader 31, the method for medicating the pharmaceuticals, and so on into the third terminal equipment 40.
On the other hand, a patient barcode �B� for identifying the inpatient 7 is provided on the body of the inpatient 7 or in the vicinity of a bed. The medical attendant reads both of the patient barcode �A� affixed on the prescription or clinical chart 1 and the patient barcode �B� provided, for example, in the vicinity of the bed by using the third terminal equipment 40. The third terminal equipment 40 judges whether the patient recognized by the patient barcode �B� coincides with that by the patient barcode �A� or not. When the patients identified by the patient barcodes �A� and �B� do not coincide with each other, the third terminal equipment 40 outputs an alarm (or a warming) via an integrated speaker, or the like. As a result, the medical attendant can understand that the prepared pharmaceuticals are erroneously carried to another patient, so that it is possible to prevent the medication mistake that the pharmaceuticals for another patient will erroneously be medicated to the different patient. Alternatively, when the patients identified by the patient barcodes �A� and �B� coincide with each other, the medical attendant medicates the pharmaceuticals to the inpatient 7 following the steps instructed in the prescription or clinical chart 1.
It is possible to use the date and time when the patient barcode �B� provided in the vicinity of the bed is read by the third terminal equipment 40 as the date and time of the medication of the pharmaceuticals instead of the time when the second terminal equipment 30 accesses the database in the server 10. In such the case, the receiver 41 transmits the date and time when the third terminal equipment 40 reads the patient barcode �B� to the server 10.
Hereupon, when the pharmaceuticals prohibited to be combined with each other are included or when the dose of at least one pharmaceuticals is surpasses the permissible dose, the first terminal equipment 20 outputs the alarm by using the buzzer, or the like (Step S19), and completes the operation. Alternatively, when the pharmaceuticals prohibited to be combined with each other are not included (NO in Step S17), the first terminal equipment 20 prints the barcodes 2 corresponding to the kinds and doses of the pharmaceuticals and the patient barcode �A� for identifying the patient by using the printer 21 (Step S21), and completes the operation.
When the medical attendant uses the barcode reader 31 for reading the patient barcode �A� and the barcodes 2 showing the kinds and doses of the pharmaceuticals affixed on the prescription or clinical chart 1 (Step S31), the second terminal equipment 30 accesses the database in the server 10 via the network 15 with using the data corresponding to the barcodes (Step S33).
When the contents of the barcode 6 coincide with the contents of the barcodes 2, the kinds and doses of the pharmaceuticals prepared by the medical attendant coincide with the those described on the prescription or clinical chart 1, so that the pharmaceuticals will be medicated to the inpatient 7. Thus, the third terminal equipment 40 is connected to the second terminal equipment 30 for memorizing the contents of the patient barcode �A� read by the barcode reader 31 into the third terminal equipment 40 (Step S59), and complete the operation.
At first, the medical attendant goes to the patient room for medicating the pharmaceuticals to the inpatient 7 with carrying the third terminal equipment 30 memorizing the patient barcode �A�, the prescription or clinical chart 1 by the doctor and the pharmaceuticals (Step S71). When the medical attendant reaches to the patient room, the patient barcode �B� provided on the body of the inpatient 7 or in the vicinity of the bed is read by a barcode reader in the third terminal equipment 40 (Step S73).
When the patient barcode �B� is read, the third terminal equipment 40 compares the read barcode �B� with the previously memorized patient barcode �A� (Step S75), and judges whether they coincide with each other or not (Step S77). When the patient barcode �B� coincides with the patient barcode �A� (YES in Step S77), the inpatient 7 coincides the patient described on the prescription or clinical chart 1, so that the medical attendant medicates the prepared pharmaceuticals to the inpatient 7 following the instruction of the prescription or clinical chart 1 (Step S79). Furthermore, the third terminal equipment 40 transmits the date and time when the patient barcode �B� is read to the receiver 41, if necessary (Step S81), and completes the operation.
On the other hand, when the patient barcode �B� does not coincide with the patient barcode �A� (NO in Step S77), the inpatient 7 is another person from the patient described on the prescription or clinical chart 1, so that the prepared pharmaceuticals may not be medicated to the inpatient 7. The third terminal equipment 40 outputs an alarm by the speaker, or the like (Step S83), and completes the operation.
In the above-mentioned embodiment, the system is configured for accessing the database in the server 10 via the network 15 by using the terminal equipments 20, 30 and 40 having the computer function. Thus, it is possible to form the prescription or clinical chart with respect to each patient as an electronic information (hereinafter, it is called �electronic clinical chart�), the electronic clinical charts are memorized in a second database in the server 10 or another server, and the electronic clinical chart in the second database is read by the terminal equipments 20, 30 and 40 as occasion demands.
Furthermore, the second terminal equipment 30 compares the information with respect to the kinds and the doses of the pharmaceuticals described on the electronic clinical chart with those obtained with using the barcodes 6 on the receptacles 4 or the packages 5 of the pharmaceuticals, and judges whether they coincide with each other or not. When at least one of the kinds and the doses of the pharmaceuticals does not coincide, the second terminal equipment 30 outputs an alarm (or warning) via a speaker, or the like. On the other hand, when the kinds and the doses of the pharmaceuticals coincide with those described on the prescription or clinical chart 1 (SIC: correctly, it should be �electronic clinical chart�), the medical attendant carries the prepared pharmaceuticals, for example, to an inpatient 7, and the pharmaceuticals will be medicated to the inpatient 7. Thus, the third terminal equipment 40 is connected to the second terminal equipment 30 for memorizing the contents such as the information with respect to the patient and the method for medicating the pharmaceuticals, and so on into the third terminal equipment 40.
The medical attendant reached to the inpatient 7 reads the patient barcode �B� provided on the body of the patient or in the vicinity of the bed by using the third terminal equipment 40. The third terminal equipment 40 compares the patient information memorized in the memory with the information of the patient barcode �B�, and judges whether the patient coincides or not.
The term �pharmaceuticals� in the above-mentioned description of the embodiment includes all the ones used in the medical field such as the instillation for supplying nutrition, poultice, and so on further to the medicine for remedy the patient. Furthermore, the barcodes are used for identifying the patient in the above-mentioned embodiment, but it is not restricted by the description. The patient can be identified with using his cornea or fingerprint, if possible.
