In order to facilitate weighing work, multiple display elements are arranged continuously -ζ, and a function is added to display the vicinity of the set weighing amount in an analog way (=j), so that the amount of excess or deficiency is displayed in an analog way. It is desirable to configure it as follows.

The drug detection device 8 and the one-line indicator lamp group 9 installed in the medicine shelf 7 will be explained with reference to a perspective view showing one part 81S of the medicine shelf 7 shown in FIG. The drug detection device 8 is provided with a detector group 81 consisting of a light emitter and a photoreceptor as shown in FIG. As shown in FIG. 5, a code plate 82 representing the code of the drug name in the medicine bottle is attached to the medicine bottle, and the code is read by the detector group 8I and output to the interface circuit 5. It is configured to be able to detect the name of the medicine placed therein, as well as detect which medicine has been removed when the medicine bottle is removed. The indicator lamp group 9 is provided corresponding to each medicine bottle placement place 72,
It is configured to turn on according to instructions from the computer.

Next, the operation of this embodiment will be explained based on the flowchart shown in FIG. FIG. 6 is a flowchart showing a program written in the read-only memory 2 or written into the program area of the RAM according to the embodiment of the present invention.

First, when the system is started, the drug detection device 8 checks whether all the medicine bottles are placed in the specified placement locations. The device 13 is activated to notify the operator, and the location of the placement error, etc. is specified using the indicator lamp group 9. Alternatively, the placement location of the entire collection bottle may be detected by the drug detection device 8 at the time of system startup and stored. In this way, the placement of all bottles in the medicine cabinet is confirmed before the start of work. The pharmacist inputs the contents of the audited prescription, and the doctor directly inputs the contents of the prescription, i.e., the name of the drug to be dispensed, its weight, and other necessary information, using the keyboard 10.The input data is stored in the random access memory 3 of the computer. At the same time as it is stored, it is displayed on the CRT II (the CRT attached to the input device and on the dispensing desk), the contents of the prescription are audited, and a signal to complete input is input. By connecting to a host computer using, for example, a computer, a doctor can also manually operate the system directly from the examination room.

To start dispensing, call up the stored prescription.

The input data is displayed on CR"F on the dispensing table. A signal flashes at the beginning of the line of the name of the medicine to be weighed, and the medicine shelf 7
Of the indicator lamp group 9, the indicator light at the location where the drug of interest is placed is lit. The pharmacist takes out the medicine bottle placed in the place where the indicator lamp is lit, and uses the electronic balance 6 to measure the medicine according to the prescription contents displayed on the CRTII, but does not take out the medicine bottle from the medicine shelf 7. When, medicine bottle coat plate 82
and the detector group 81 on the shelf 71 detect and output data on the medicine bottles taken out. Here, the stored prescription data is compared with the prescription of the medicine bottle taken out, and if there is a discrepancy, the alarm device 13 is activated to notify the user, and the user cannot move on to the next task unless the correct medicine bottle is taken out. Can not. Take out the regular medicine bottle and put it on the CRT
When the electronic balance 6 weighs the prescribed weight displayed on the electronic balance 6, when the pharmacist determines that the prescribed weight matches the weighed amount based on the value displayed on the electronic balance 6, the weighed value is input into the computer. Perform operations. This may be configured to give an input command by pressing a switch or the like, or may be configured to automatically supply weighed value data to the computer when the medicine is unloaded from the electronic balance 6 along with the weighing paper. . When this weighed value data is input, that value is compared with the prescription data in the random access memory 3, and if the difference is within a preset tolerance value, it is printed out on the printer 12. If the difference exceeds the allowable value, the alarm device 13 is activated, the printer 12 is not activated, and the weighing operation must be repeated and the user cannot proceed to the next operation.

When the weighing of one medicine is completed, the medicine bottle is placed in the medicine cabinet 7.
At this time, the drug detection device 8 reads the coat of the returned medicine bottle and determines whether it has been returned to the correct location, that is, whether it is correct by comparing it with the placement position data at the time of system startup. However, if there is a mistake in the return, the alarm device 13 is activated and a correction instruction is given.

After that, for the next drug to be weighed, a blinking light appears at the beginning of the drug name line on the CRT, and an indicator lamp lights up at the location where the drug is placed, and the weighing process continues in the same manner until all the drugs written on the prescription are weighed. When the weighing of the medicine is completed, a prompt to input data for the next prescription is displayed.

In addition, when the weighing based on one prescription is completed and the weighing value of the last drug is OK, all drug names, their weighing results, and other contents are printed out on the printer 12 according to the format of the prescription. is configured to do so. The pharmacist can notify the completion of the work by printing it out. The data printed out in this way has two copies of the patient's name, usage, dosage, date of dispensing, pharmacist's name, etc., and one copy can be pasted on the medicine bag, eliminating the hassle of creating medicine bags. Ru. The printout can be kept as a copy at the pharmacy, and can also serve as proof of the work done at a later date.

Note that an auxiliary storage device may be connected to the computer in the above embodiment. It is also possible to add a drug price calculation program to the computer program and use data at the time of dispensing to calculate drug prices. Furthermore, it is also possible to connect to a post computer and use input data for drug inventory management.

(F) Effects As explained above, according to the present invention, first, when the system is started, the placement position of each medicine bottle on the medicine shelf is confirmed, and if there is an error such as omission of placement, an alarm is issued. Since it is possible to instruct corrections and then check whether the medicine has been dispensed according to the data written in the prescription, there is no possibility of erroneously dispensing medicines other than those written in the prescription. In addition, the weighed value of each drug is
The weight is compared with the weight specified in the prescription, and only when the difference is less than a preset tolerance value can the next operation be carried out, thereby preventing errors in weighing. In addition, since checks are automatically and strictly performed to ensure that prescriptions are being dispensed, errors in weighing operations can be prevented in advance, increasing the reliability of dispensing and further reducing work. Since everything is kept as a record, it contributes to ensuring the safety of medication.
