Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is for improving the safety and workability of dispensing by accurately and efficiently weighing drugs according to a prescription prepared by a doctor. Regarding the system.

<Conventional technology> In general, dispensing work at pharmacies inside and outside hospitals and clinics involves pharmacists weighing and dispensing the specified weight of each drug on a balance based on the contents of a prescription prepared by a doctor. However, if there is a mistake in the amount of medicine to be dispensed or the amount to be weighed, there is a risk of a serious accident, and pharmacists must always carry out their work in a state where there is absolutely no room for error, and their efforts are The impact was enormous, including psychological ones.

Therefore, in order to improve the credibility of dispensing operations and ensure the safety of medication, the applicant has already incorporated drug detection means such as electronic balances and code readers into the computer system, and has incorporated drug detection means such as electronic balances and code readers into the computer system. By inputting the data of the name and the weighed amount, you can memorize it and check whether the drug taken out from the medicine cabinet matches the memorized data or whether the weighed amount of the drug by the electronic balance matches the memorized data. We are proposing a system that can detect whether the prescriptions match, prevent mistakes in dispensing work, reduce the burden on pharmacists, and improve work efficiency.

issue).

<Problems to be Solved by the Invention> Incidentally, in the system based on the above-mentioned proposal, prescription data is input by operating a keyboard built into the system, or by data transfer from a host computer to the system. is taken.

When inputting prescription data from a keyboard, the dispensing operation has to be stopped each time the prescription data is input, and the efficiency of the operation is not very good.

In addition, when transferring prescription data from the host computer, it is necessary to transfer the data sequentially from the host computer as the dispensing process progresses. In order to respond to detailed requests according to convenience, such as postponing processing, etc., it becomes necessary to appropriately exchange prescription data with the host computer.

For this purpose, it is necessary to change the program of the host computer to one that can cope with these situations, and the load on the host computer increases as the number of accesses increases.

In order to reduce this burden and to minimize the need to change programs on the host computer, a small-scale relay computer such as a personal computer is interposed between the system and the host computer, or a keyboard, etc. If manual input is employed, it is conceivable to provide a computer for that input. Here, data reception between the computer for relay or manual input and the drug weighing system is carried out at the time of delivery.
After completing one dispensing task, the waiting time until receiving and receiving data for the next dispensing is related to work efficiency. A high-speed device is required, which increases costs.

The present invention has been made in view of the above, and even if a slow processing speed computer is used as the above-mentioned relay or manual input computer, data reception can be performed at high speed without increasing the waiting time due to handing over. The aim is to provide a possible drug weighing system.

Means for Solving the Problems> A configuration for achieving the above object will be explained with reference to the basic conceptual diagram shown in FIG. The present invention provides an electronic balance a that can output weight measurement data to the outside, a drug detection means that outputs data on the name of a drug to be weighed by the electronic balance, and an input device for inputting prescription data. Comparing the data output from the means C, the first storage means d capable of storing the input prescription data for a plurality of prescriptions, and the drug detection means and the data related to the name of the drug among the prescription data, Drug coincidence detection means e that notifies you when they do not match, and weighed value coincidence detection that compares the weighed amount data of the prescription data with the weight measurement data from the electronic balance a and notifies you when they do not match. In a system equipped with a means f, data of a prescription to be compared in the medicine coincidence detection means e and the weighed value coincidence detection means f, and at least another prescription to be dispensed next time in addition to the data of the prescription. a second storage means g for storing data; a determination means for determining whether data regarding at least two prescriptions is stored in the second storage means g; a data transfer command means i for transferring and storing the contents of the first storage means d to the second storage means g;
The second storage means g is characterized by being configured to store data regarding at least two prescriptions to be dispensed this time and the next time.

Function> The prescription data to be compared in the drug coincidence detection means e and the weighed value coincidence detection means f, that is, the prescription data currently being dispensed, is stored in the second storage means g, and this second storage means In addition, data for at least one other prescription to be dispensed next time is automatically stored in g and placed on standby during the current dispensing operation, so the next dispensing can be started immediately after the current dispensing operation is completed. Even if a low-speed computer is used for relay purposes, there is no waiting time for receiving and passing data.

<Example> Embodiments of the present invention will be described below based on the drawings.

FIG. 2 is a block diagram showing the configuration of an embodiment of the present invention.

The dispensing work control section 1 is installed on the dispensing table, and includes a group of equipment required for actual dispensing work, that is, the dispensing terminal 1.

and a printer 15. Among these, the dispensing terminal 1) has a CPU and a ROM.

Mainly based on a microcomputer consisting of RAM, etc.
It consists of an input/output control device that controls the input/output of the data, and a communication line (R3
-232C standard line, etc.).

The dispensing computer 2 is composed of, for example, a personal computer, and has an area set in its built-in memory to store a large number of prescription data, and as described later, the stored contents are sequentially transferred upon request from the dispensing terminal 1). It is configured so that it can be done. This dispensing computer 2 is
Furthermore, it is connected to a host computer 3 and a prescription data input terminal 4 via a communication line, and the above-mentioned prescription data is input to the memory of the dispensing computer 2 through the host computer 3. It is configured so that it can be performed from either the prescription data terminal 4 or the keyboard 21 attached to the dispensing computer 2.

R in the dispensing terminal 1) in the dispensing work control section 1
Two prescription data storage areas each storing data about one prescription are set in the AM, and these are hereinafter referred to as prescription memory (I) and prescription memory (n), respectively.

Further, a program to be described later is written in the ROM in the dispensing terminal 1). Such a dispensing terminal 1) is equipped with the aforementioned operation console 12. Electronic balance 13. A code reader 14 and a printer 15 are each connected.

The operation console 12 displays a start key 12a for giving a command to the dispensing terminal 1) to start dispensing work for one prescription, and the name of the drug to be taken out from the medicine shelf based on prescription data as described later. Display 1 for
2b.

The electronic balance 13 has a weighing value display 13b for displaying the measured weight of the medicine placed on the pan 13a, as well as a weighing value display 13b.
It is equipped with a weighing target value display 13c for displaying the weight to be weighed based on the prescription data from the dispensing terminal 1), and can transfer the weighing data to the dispensing terminal 1).

The code reader 14 reads the code related to the name of the medicine taken out from the medicine shelf and sends the result to the dispensing terminal 1).
This is a device for outputting to. In other words, each drug container on the drug shelf has a code plate affixed to its bottom surface etc. that encodes the name of the drug stored inside, and each drug container taken out from the drug shelf is coded with this code. The name of the medicine taken out is read by placing it on the reader 14, and the result is input into the dispensing terminal 1).

The printer 15 is automatically driven by a command from the dispensing terminal 1), and is configured to print out the contents of the dispensing each time a dispensing work based on one prescription is completed.

FIG. 3 is a flowchart showing the program written in the ROM in the dispensing terminal 1), and the operation will be described below with reference to this figure.

Upon activation of the dispensing work control unit 1, data regarding one prescription among the prescription data stored in the dispensing computer 2 is first transferred to the dispensing terminal 1.
) stored in the prescription memory (I) in (STI, 5
T2). When the pharmacist actually starts dispensing, he presses the start key 12a on the console 12 (Sr3). As a result, the contents of prescription memory (I) are changed to prescription memory (II).
) (Sr1) and its prescription memory (II
), one of the names of the medicine to be dispensed is displayed on the display f2b. (Sr1).

The pharmacist takes out the corresponding drug container from the drug shelf according to this display and places it on the code reader 14, but the drug name data from the code reader 14 is compared with the drug name displayed on the display 12b, and if there is a discrepancy, issue an alarm,
If they match, proceed to the next step (Sr1,
5T7).

In the next step, the target value display 13 of the electronic balance 13
At c, based on the contents of the drug memory (U), the drug displayed on the display 12b of the proposal table 12, that is, the weighed amount of the removed drug is displayed (Sr1).

The pharmacist uses an electronic balance 1 to weigh out the medicine according to the indicated value.
The so-called weighing operation, in which the drug is placed on the tray 13a in step 3, is started, but during this time, it is checked whether the prescription data to be dispensed next time is stored in the prescription memory (1). is determined (Sr1), and if it is not stored, the prescription data in the memory of the dispensing computer 2 is transferred, and the data is stored in the prescription memory (1) of the dispensing terminal 1) (STI O, STI 1)
. Here, since weighing out one drug generally requires at least several seconds, there is sufficient time to recall the prescription data from the memory of the dispensing computer 2 and to transfer the data to the dispensing terminal 1) using a serial signal. It is in.

During weighing work by the pharmacist, when the value displayed on the measured value display 13b of the electronic balance 13 reaches the vicinity of the value displayed on the target value display 13c, the pharmacist takes the sample down from the plate 13a or weighs it. By performing a key operation indicating completion, the measured value at that point is transferred to the dispensing terminal 1) (ST12), and this measured value is used as the weighed amount of the drug,
That is, it is determined whether or not the target value display 13c is within the allowable error range, and if it is not, an alarm is issued, and if it is, the process proceeds to the next step (S
T13), determine whether or not weighing of all drugs has been completed regarding the prescription data in the prescription memory (II), and if it has not been completed, return to Sr1 and display the next drug name, and the same routine is performed. is repeated (ST14)
. If all weighing for one prescription has been completed, all measurement results are transferred to a buffer in the RAM (ST15).

At this point, when the pharmacist presses the start key 12a on the console 12 to dispense the next prescription, the prescription data already stored in the prescription memory (1) in the dispensing terminal 1) is immediately transferred to the prescription memory (1). n) and transferred to (S
r1), the routine for the next prescription is similarly executed.

That is, when dispensing work based on one prescription is completed, it is possible to automatically move on to the next dispensing work based on the prescription data received during that work without waiting time.

All measurement results for one prescription are transferred to a buffer and then automatically printed out, for example by the print routine shown in FIG. 4, and the results can also be returned to the dispensing computer 2 if necessary. can. This routine is shown in FIG.
By inserting the routine at an appropriate location such as between 12 and 12, no waiting time occurs due to execution of this routine.

FIG. 5 is a flowchart showing the main part of a program according to another embodiment of the present invention, which can deal with urgent dispensing. The routine shown in FIG. 5 is inserted immediately before 5T12 in FIG. 3, and when a preset command from the dispensing computer 2, that is, an emergency interrupt command occurs, the routine stores the next dispensing information in the prescription memory (1). By once returning the contents to the dispensing computer 2 and storing the urgent prescription data in the prescription memory (1), this urgent prescription will be processed in the next dispensing. Without this routine, even if the order in the memory of the dispensing computer 2 is changed, emergency prescriptions will be dispensed one after another.

Note that if the dispensing control unit 1 is equipped with a display device such as a CRT and connected to the dispensing terminal 1) or the dispensing computer 2 to display all data for one prescription at once, the pharmacist can It is more efficient because the next chemical to be weighed can be known in advance.

Furthermore, by connecting an accounting terminal to the host computer 3, drug price calculation can be made online, and the system can also be developed to enable drug inventory management and the like.

<Effects of the Invention> As explained above, according to the present invention, among the prescription data group input in the drug weighing system and stored in the first storage means, the prescription data to be provided for the current dispensing is In addition, a second storage means for storing another prescription data to be dispensed next time is provided, and it is determined whether at least two prescription data are stored in the second storage means, If the prescription data is not stored, transfer the prescription data from the first storage means to the second storage means, and
Since this determination and transfer is configured to be executed sequentially while the system is in operation, when dispensing work for one prescription is completed, the next one is immediately executed without transferring data from the relay computer or input computer. As a result, even if a low-speed computer of about 8 bits is used as a relay or input computer, there is no waiting time, which is advantageous in terms of cost.

In addition, it is extremely important to proceed to the next dispensing immediately after completing one dispensing for the smooth flow of dispensing work, and it is not only an efficiency problem for pharmacists who have to wait several seconds. It also has a great effect on psychological effects, such as not causing irritation.
