Description

A Pulverizing Apparatus of Pills

The present invention relates to a pill crusher, and more particularly, it is configured so that pills that are prescribed and packaged in a medicine bag can be crushed into a powder state without the medicine bag bursting. It relates to a grain crusher that enables the crushing operation.

In general, oral medicines prescribed to patients are divided into pills, powdered medicines, and liquid medicines, and there are many cases where it is difficult to take the medicine depending on the health condition or age of the user.

In particular, in the case of infants, children, or elderly patients, it is difficult to take bulky pills directly, so in the process of dispensing the drug at a hospital or pharmacy, some patients grind the pill into a powder state, and prescription is made to the patient.

In the case of the most commonly used conventional pill crusher, as shown in FIG. 1, it takes a lot of time because the operator puts the pill in a mortar-shaped container and grinds or crushes the pill using a pestle, and this Due to the inconvenience of requiring a lot of labor for the worker, and since the work of grinding different pills for each patient into powder using one mortar is performed, the efficiency is lowered because the mortar has to be cleaned and then the other drug must be ground.

In addition, even in a small amount during the conventional pill grinding operation using a mortar, the drug is lost in the process of pulverizing and packaging the drug, resulting in a decrease in the amount, which is disadvantageous for patients who have to take the prescribed amount of the drug. There were many.

A mechanical grinder was also used to solve the problems that occur when grinding the pills using the conventional mortar method.

However, when using a mechanical grinder, it is difficult to grind a small amount of pills, so a lot of medicines are put at once and then the crushed medicines are distributed using a spoon. Inconvenience of packaging the medicine and the inconvenience of cleaning the inside of the grinder every time different medicines are grinded still occurred.

In order to solve these problems in the prior art, a device for crushing the pills contained in the bag in the state in which the prescribed medication is contained in the bag has also been devised.

As an example, the 'pill crusher' of Patent Registration No. 10-1311823 (registration date: 2013.09.16) has been devised.

The 'pill crusher' is a driving roller having an '8'-shaped cross section, and concave and convex parts are sequentially formed to correspond to the driving roller, and the packaged drug is inserted between the rotating driven roller and is configured to be pressurized. It was able to solve some of the shortcomings that occurred during the crushing operation of pills.

In another embodiment, the 'pill crusher' of Patent Registration No. 10-1763640 (registration date: 2017.07.26) has been devised.

The 'pill crusher' had a structure in which the medicine paper containing the pills passed through the inlet through which the pills were passed from the top to the bottom, and passed between two or more pairs of rollers up and down to pulverize the pills.

In this way, most of the conventionally devised pill crushers are configured to crush the pills contained in the bee bags by inserting a pill bag between a pair of rollers corresponding to each other. It was designed to further increase the efficiency of the drug crushing operation while preventing it from forming.

However, in the case of such a conventional roller-type tablet crusher, the configuration of the device is large and somewhat complicated, and when the frictional force and rotational force between the rollers corresponding to each other occur, there is often a problem in that the medicine bag is torn.

In addition, a number of pill crushers devised in the prior art cannot selectively crush a large number of pills included in the medicine bag, so they do not need crushing or even crush capsule-type pills that do not have to be crushed, so their use is limited. there was

Therefore, the present inventor devised the present invention in order to solve the problem that the pills are put into the pulverizer with a bag, and the pill bag is torn when the pills are pulverized in the process of passing through the pill pulverizer.
