Abstract

PURPOSE:To enhance the data processing capacity of a weighing apparatus, by performing the storing, detecting and comparing processings of the data relating to the name of a medicine by using a numerical value code. CONSTITUTION:The medical prescription recording data from an input means (a) is stored in a memory means (b) and displayed on a display means (h). Next, a medicine detection means (c) outputs the data relating to the name of a drug to be weighed. Subsequently, a drug coincidence detection means (d) compares the drug data outputted from the drug detection means (c) with the data recorded to the medical prescription in the memory means (b) and, when both data do not coincide, non-coincidence is informed. The wt. measuring data of each drug of an elecronic balance (e) is compared with the wt. of each medicine weighed based on the medical prescription in the memory means (b) by a weighed value coincidence detection means (f) and, when the difference therebetween exceeds an allowance value, this state is informed. Next, a medicine code registering means (g) stores the name of a drug group and respective medicine codes so as to correspond to the numerical codes set with respect to the medicines.

Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is used in pharmacies inside and outside hospitals and clinics to monitor the weighing operation of drugs and prevent errors so that they are dispensed without errors according to prescriptions prepared by doctors. This invention relates to a device that detects and warns, prevents accidents, and at the same time records all work details.

<Prior Art> Conventionally, when dispensing drugs, a pharmacist uses a mechanical balance to weigh out and mix several types of drugs on a drug shelf according to a prescription. However, if you accidentally take the wrong medication or weigh out the wrong amount, there is a risk of a serious accident because there is no checking function other than that of the pharmacist. Therefore, pharmacists had to carry out their work at all times with absolutely no room for error, and the effort was enormous, including mental work.

Therefore, in order to improve the reliability of dispensing operations and ensure the safety of medication, the present applicant has incorporated electronic balances, code leagues, etc. into the computer system, and has developed a computer system that can record prescription contents, that is, drug name data and its weighing data. By inputting data, it is memorized, and it is possible to detect whether the medicine taken out from the medicine cabinet matches the stored data, or whether the amount of medicine weighed by an electronic balance matches the stored data. We have already provided a device that can prevent mistakes in dispensing operations (Japanese Unexamined Patent Publication No. 6O-2
0122).

<Problems to be solved by the invention> By the way, for drug name data, inputting the name itself as data, storing it, and performing comparison processing requires a large number of input characters (and a large number of data bits). This is not only inefficient, but also increases the frequency of data bit errors.

Furthermore, when storing a large amount of prescription data or keeping records of dispensing operations, a considerable amount of storage capacity is required just for the data on drug names.

The present invention aims to improve such drug weighing systems, and more specifically, to improve the efficiency of data processing in such devices and reduce the burden on storage devices.

Furthermore, the present invention aims to further improve the safety of dispensing operations by reducing the frequency of occurrence of data bit errors.

<Means for Solving the Problems> The configuration of the present invention will be explained based on the functional block diagram shown in FIG.

The input means a inputs the data written in the prescription, that is,
This is for inputting at least data relating to the names of drugs to be prepared and weighed weight data of each drug, and the input data from this input means a is stored in the storage means. Further, this input data is displayed by the display means. The drug detection means C outputs data related to the name of the drug to be weighed. The drug match detection means d compares the drug data output from the drug detection means C with the drug data in the storage means, that is, the drug data written in the prescription, and notifies the drug data when they do not match. .

The electronic balance e can output the weight measurement data to the outside, and the weight measurement data of each drug by the electronic balance e is detected based on the prescription data in the storage means by the weigh value coincidence detection means. It is compared with the weighed weight of the drug, and if the difference between the two data exceeds a preset tolerance value, a notification to that effect is given.

The drug code registration means g stores the name of the drug group and each drug code in correspondence with the numerical code set for each drug, and at least the drug detection means C
Discovery of drug data by.

The storage of drug data in the storage means d and the comparison of drug data in the drug coincidence detection means d are configured to be performed using the above-mentioned numerical code.

<Effect> By using the numerical code registered in the drug code registration means g for processing such as detection, storage, and comparison of drug data within the system, the number of bits of data related to the name of each drug is reduced. This improves data processing efficiency and reduces storage capacity.

Also, it is possible to reduce the occurrence of data bit errors during data transfer.

<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 device is CPU1. RAM2. ROM3. RAM 4 (hereinafter referred to as backup RAM 4) whose power source is backed up by a battery, electronic balance 5° code reader 6,
External recording device 7 comprising a printer 7a and a disk 7b. Consists of CRT8 and keyboard 9,
These are connected to each other via pass lines.

The RAM 2 includes a work area 2a that stores data in the CPUI process, and a prescription memory 2b that stores prescription data input from the keyboard 9. Further, the ROM 3 has a program storage area 3a for storing programs to be described later, and an area as a first drug registration memory 3b for storing drug names etc. in correspondence with numerical codes as described later. . The back amplifier RAM 4 is the first drug registration memory 3b described above.
A second drug registration memory is configured for registering new drugs that are not registered in 2018 in association with numerical codes.

The electronic balance 5 can display the weight measurement result on the display 5a and output the value as a digital signal.

The code reader 6 is provided at a location where each drug container is placed on a drug shelf (not shown), and the code reader 6 is provided in a white color corresponding to the name of the drug contained in the drug container, which is pasted on the bottom of each drug container. /Equipped with a group of photosensors that detect the reflected light from the code board, which is displayed in binary by painting it black, and read the numerical code. Here, the numerical code on the code plate corresponds to the numerical code registered in the first or second drug registration memory described above.

The output of this code reader 6 is monitored by the CPUI, and the output of the code reader 6 is monitored by the CPU to determine whether a specified drug is placed in a specified location on the drug shelf or when a specified drug container is taken out from the drug shelf. It is possible to detect whether

In addition, the medicine shelves are marked according to the placement location of each medicine container.
Each of them is provided with an instruction lamp that can be turned on in response to a command from the CPUI.

In the first or second drug registration memory, drug names and their drug codes are stored in correspondence with numerical codes, as shown in Table C]. The numerical code is a 1-byte binary code, and the drug name and drug code are 10-byte and 12-byte ASCII codes, respectively.
I remember it with te. The aforementioned code board represents the name of the medicine contained in the medicine container by dividing the binary code based on this [table] into black and white.

All drugs used in this system are
Or it is registered in the second drug registration memory.

Here, the additional registration of the drug is performed by recording it in the second drug registration memory constituted by the backup RAM 4.

Next, the operation of the embodiment of the present invention will be described. Figure 3 is ROM3
3 is a flowchart showing a program written in the program storage area 3a of FIG.

First, when the system is started, it is checked whether each drug container is placed at each specified location on the drug shelf by checking the numerical code from the code reader 6, and if there is a placement error, an alarm is issued.

When the contents of the prescription, that is, the name of the drug to be dispensed and the amount to be weighed, are entered using the keyboard 9, this data is stored in the prescription memory 2b of the RAM 2. In this input, a table is prepared in which drug names are associated with their numerical codes, and drug name data is entered in numerical values. Alternatively, the first and second
It is also possible to display the contents of the drug registration memory in advance and to indicate the corresponding one with a light ben.

When dispensing, the contents of the prescription memory 2b are displayed on the CRTB, and an instruction lamp provided on the medicine shelf indicates where to place the medicine container containing the medicine to be weighed. When the corresponding drug container is taken out, the CPU 1 detects an output from the code reader 6 indicating that nothing is placed at that location (medicine containers are placed in all other locations) The numerical code of the specified drug and the numerical code in the prescription memory 2b are compared, and if they do not match, WED is performed by displaying an error message on the CRTa.

Take out the drug container that matches the contents of the prescription memo IJ 2 b, and place the weight on the electronic balance 5 based on the CRT8 display.
When the weight is weighed, the weighed weight data is compared with the contents of the prescription memory 2b, and if the difference exceeds an allowable value, an alarm is generated.

When the value is below the allowable value, the drug name and weighed weight are printed out on the printer 7a. At the same time, the numerical code corresponding to the drug name and the weighed weight are recorded on the disk 7b.

When the weighing is completed, the drug container is returned to the drug shelf. At this time, the code reader 6 reads the numerical code of the returned drug container to check whether it has been returned to the correct position and to avoid mistakes. If so, an alert will be issued.

After completing the above operations and weighing each drug in one prescription, the system waits for the next prescription data to be input. Alternatively, when a plurality of prescription data have already been input, the next prescription data is displayed on the CRT 8.

To supplement the data flow in the above embodiment, when a numerical code related to a drug name, for example 3, is keyed in using the keyboard 9, that binary code is stored in the prescription memory 2.
However, when displaying the drug name on the CRT 8 or printing the drug name using the printer 7a,
The above numerical code is compared with the contents of the first or second drug registration memory, and the corresponding drug name is assigned the ASCII code 1.
0 byte is transferred to the CRT 8 or printer 7a.

In addition, when inputting data related to drug names, the drug name or drug code may be entered without being limited to numerical codes. In this case, the drug name etc.
Alternatively, it will be verified in the second drug registration memory, and the corresponding numerical code will be stored in the prescription memory 2b.

Further, in the above embodiment, the RAM 4 whose power source is bank-amplified by a battery is used as the second drug registration memory for new registration, but it is also possible to use a durable memory that does not require a power-back amplifier.

Further, in the above embodiment, the code reader 6 was installed at the place where each drug container was placed on the drug shelf, but the code reader 6 was not installed on the drug shelf but was installed separately, and the removed drug container was placed in the separate place. Of course, it may be configured to read the numerical code of the drug name by placing it on the code reader 6 of the computer.

Furthermore, in the above embodiment, the CPUI is connected to the host CPU.
For example, if it is linked to a terminal device such as a prescription input system in a clinic or an accounting system in an office, it will be effective as a terminal system for a comprehensive medical system in a large hospital. - By incorporating the numerical code along with the drug name and drug code into the CPU database, it is possible to improve the efficiency of drug data transfer and processing within the integrated system.

<Effect> As explained above, according to the present invention, drug names and drug codes are stored in correspondence with preset numerical codes, and data related to drug names can be stored, detected, compared, etc. Since processing is performed using numerical codes, the number of data transfers is reduced, processing efficiency is improved, and the required storage capacity is reduced.
Furthermore, the occurrence of data bit errors can be suppressed, and the safety of dispensing operations can be further improved.
