[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weighing apparatus capable of mixing various substances to obtain a sample having an arbitrary mixing ratio with good reproducibility. The present invention relates to a weighing apparatus suitable for use in preparation of medicines or dispensing in hospitals and pharmacies.

[0002]

2. Description of the Related Art When a sample is prepared by mixing a plurality of components at a predetermined ratio, each component is generally weighed and mixed with a balance or the like. For example, it is necessary to prepare again the same sample as an already prepared sample. Has occurred, the names of the components and the weighed values described in the notebook or the like in the previous mixing operation are searched for, and the weighing operation is performed with reference to these.

In dispensing work in hospitals, pharmacies, and the like, dispensing may be performed under the name of "regular prescription" by referring to the previous prescription or by partially changing the prescription.

[0004]

However, in the above-described conventional reproduction operation of mixing, etc., a mistake in the description of the previous weighing result and a measurement error or judgment error of each component in the current weighing operation. It is not an exaggeration to say that there is a risk that many human mistakes will intervene, and there is no guarantee on the reproducibility of an actually recreated sample.

[0005] The present invention has been made in view of such a point, and it is difficult for human error to intervene in the weighing operation for preparing or mixing a plurality of components, and it is possible to guarantee the reproducibility of a sample. The purpose is to provide a weighing device.

[0006]

A configuration for achieving the above object will be described with reference to a basic conceptual diagram shown in FIG. 1. The present invention provides a balance a for outputting weighing data,
A component information input means b, a control means c, a key d for designating either a registration mode or a reproduction mode for the control means c, and information from the input means b based on a command from the control means c Registering means e for associating and registering the weighing data from the balance a as composition information; display means f for displaying the composition information read out from the registration means e based on a command from the control means c; Means for comparing the composition information with the data from the input means b and the weighing data from the balance a, and the notifying means h for notifying the result of the comparison. In the reproduction mode, the composition registered in the registration mode is used. A specific item can be searched for and displayed from the information, and the display contents, the input data from the input means b, and the weighing result by the balance a can be displayed for each component. It characterized by configured to notify the result compared to and.

[0007]

When a registration mode is selected when a new sample is created, component information of the sample and weighing data for each component are registered in the registration means e. When the same sample is reproduced, by selecting the reproduction mode, the corresponding one is searched from the registration means e and its component and each weighing data are displayed. We can perform weighing. At this time, the registered content is compared with the current weighing component and weighing data for each component by the comparing means g, and the result is reported, so that there is no danger of human error intervening.

[0008]

FIG. 2 is a block diagram showing a configuration of an embodiment of the present invention. The electronic balance 1 is connected to the microcomputer 2 and the measurement result is taken in the microcomputer 2 in the form of digital data. The microcomputer 2 includes a CPU 21, a ROM 22, a RAM 23, an input / output interface 24, and the like.
A program corresponding to a registration mode and a reproduction mode, which will be described later, is written in the storage 22, and the input / output interface 24 stores the electronic balance 1, the barcode reader 3, and the microcomputer 2 in the registration mode or the reproduction mode. A keyboard 4 for giving an instruction as to whether or not, and inputting various kinds of information, a display device 5 using a liquid crystal panel or the like for displaying component information and its weight data, etc., and printing for printing barcode labels. The device 6 and the external storage device 7 are connected.

FIGS. 3 and 4 are flowcharts showing the contents of the program written in the ROM 22. FIG. 3 shows a routine when the registration mode is selected, and FIG. 4 shows a routine when the reproduction mode is selected. ing. When the registration mode is selected by the keyboard 4, as shown in FIG. 3, when a bar code label indicating the contents is attached to the container containing each component, by the bar code reading device 3, or By inputting the component name from the keyboard 4 (ST11), the component information is stored in the RAM 23 (ST12). Then, when the electronic balance 1 weighs the component by a desired amount (ST13), the weighing data is obtained. It is stored in the RAM 23 in pairs with the component information (ST14).

After all the components have been weighed out, the fact is input by the keyboard 4 (ST15).
The respective component information and the respective weighing data in 3 are stored in the external storage device 7 (ST16), and a bar code label on which a bar code corresponding to the stored content is recorded is printed by the printing device 6 (ST16). ST17). Affixing this barcode label to a container for holding the sample created in the registration mode is useful when the following reproduction mode is executed.

When the reproduction mode is selected on the keyboard 4, as shown in FIG. 4, the bar code label attached to the container containing the sample to be reproduced is read by the bar code reading device 3. Read (S
T21). The microcomputer 2 accesses the external storage device 7 from the result of reading the barcode, searches the corresponding composition information (component information and measurement data stored in the registration mode), and displays the content on the display device 5. (ST22).

The operator prepares a container containing each component while observing this display, and uses the barcode reading device 3 when a barcode label representing the component is attached to each container, or uses the keyboard 4 when not. When the component information is input one by one (ST23), the component is compared with the registered contents (ST24), and the result is displayed on the display device 5.
(ST25, ST26). After confirming that the components match, the components are weighed by the balance 1 (ST27), and the weighing results are compared with those of the registered contents (ST28), and are within the tolerance set in advance by the keyboard 4. Whether the display device 5
(ST29, ST30). When the weighing of all the components is completed within the allowable error, the display device 5
Is displayed (ST31, ST32), and the operator is notified that the sample has been properly reproduced.

In the above embodiment, the comparison result between the weighing data of each component and the registered data in the reproduction mode is performed by the display device 5. The result of the comparison is reported by the weighing value display attached to the electronic balance 1. May be done by
Alternatively, the display may be performed by a sound such as a buzzer other than the display. Further, in the above embodiment, the barcode is used for inputting the component information and for searching the registered contents.
Of course, other known recording media such as a magnetic card and an ID card can be used instead. In this case, the barcode reading device 3 and the printing device 6 may be changed to a reading device and a recording device corresponding to each recording medium.

Further, when comparing the weighing data registered in the registration mode with the weighing data in the reproduction mode, it is not always necessary to set the allowable error range from a keyboard or the like as in the above embodiment. For example, it is possible to write a certain allowable range in the ROM 22, but by making this setting possible,
The versatility of the device is improved.

Further, in the reproduction mode, a part of the information registered in the registration mode is changed and displayed by the search in the registration mode so that a sample having a slightly different composition can be prepared. The composition information can be changed, added, or deleted from the displayed contents by operating the keyboard 4 or the like, and furthermore, the weight value of each component can be changed. It may be configured to report the result.
It is more convenient if the composition information thus obtained can be registered.

Further, the weighing result in the normal reproduction mode as in the above embodiment can be registered as a subdirectory of the original registration data, whereby the composition of each reproduced sample can be registered. It will be recorded, and the reliability will be further improved.

[0017]

As described above, according to the present invention, in the registration mode, each component information of the sample measured and the respective weighing data are registered, and in the reproduction mode, the already registered composition information is displayed. In addition to being displayed on the device, the weighing data at the time of reproduction is compared with the registered data for each component and the result is reported, so that the worker can record the same work on the notebook when creating the first sample, the same This eliminates the task of searching for the relevant records when preparing the sample and the task of judging excess or deficiency of each component. This not only improves the efficiency of weighing work, but also involves human error. There is very little room to improve the reliability of the replicated sample, which in turn guarantees that the composition of the replicated sample is within a specified error with respect to the composition of the original sample. Become.
