Description

The present invention relates to a drug dispensing device, and more particularly to a drug dispensing device that packages and dispenses powdered medicine in doses.

In recent years, large hospitals and large-scale pharmacies have introduced powder dispensing devices and drug dispensing devices having a powder packaging function. Here, the powdered medicine packaging device is a device that individually packages each dose of powdered medicine based on prescription information. The powder packaging device can be used to automate most of the work of packaging powders in single doses.
The conventional drug dispensing device is composed of, for example, a powder dispensing unit that distributes powdered medicines for each dose as disclosed in Patent Document 1, and a packaging device that individually packages the distributed powdered medicines. Further, the powder distribution unit has a powder feeder, a distribution plate, and a scraping device. In the conventional drug dispensing device, the pharmacist checks the doctor's prescription and takes out the medicine bottle containing the prescribed powder from the medicine rack. Then, the total weight of the prescribed specific powder is weighed using a scale such as a balance. Then, the weighed powder is put into the hopper of the powder feeder, and the trough of the powder feeder is vibrated to drop the powder onto the distribution pan. At the same time, the distribution plate is continuously rotated at a constant rotation speed to evenly disperse it in the grooves of the distribution plate.

After that, the scraping plate of the scraping device is dropped into the groove of the distribution plate, the distribution plate is rotated by an angle according to the number of distribution plates, and the powder for one dose is collected on the front side of the distribution plate. Then, the scraping plate is rotated, and the powder is scraped out of the distribution plate by the scraping plate, sent to the packaging device side, and packaged in the packaging device one by one.

In the conventional drug dispensing device, a pharmacist had to take out a medicine bottle containing a desired powder from the medicine rack and weigh a predetermined amount of powder from the medicine bottle. We have succeeded in developing an automated drug dispensing device (Patent Document 2).

The drug dispensing device developed by the present applicant and disclosed in Patent Document 2 has a shaking table arranged around a distribution pan. In the drug dispensing device disclosed in Patent Document 2, a load cell is provided on the shaking table as a measuring means.
Further, the drug dispensing device disclosed in Patent Document 2 includes a container shelf for accommodating a large number of drug containers and a robot for taking out the drug container from the shelf and installing it on a shaking table.
In the drug dispensing device disclosed in Patent Document 2, a robot takes out a drug container from a container shelf, moves it to a shaking table, vibrates the drug container, and drops powder directly from the drug container onto a distribution dish. In addition, the amount of powdered powder dropped is detected by monitoring the weight of the drug container with a load cell attached to the shaking table.
The subsequent steps are the same as in the past, in which the distribution dish is continuously rotated at a constant rotation speed to evenly distribute (distribute) the powder in the grooves of the distribution dish. Then, the scraping plate of the scraping device is dropped into the groove of the distribution plate, the distribution plate is rotated by an angle according to the number of distributions, the powder for one dose is collected on the front side of the scraping plate, and the powder is powdered by the scraping plate. Is scraped out of the distribution plate, sent to the packaging device side, and packaged in the packaging device one by one.
