Abstract

The device for delivery of a specified number of solid objects, in particular, tablets comprises a delivery disk (3) with delivery holes located between an adapter (4) and a lid (2), a delivery wheel (6), and a rotation limiter (5). Independent claims are also included for: (1) producing the proposed delivery device; (2) a device and a method for delivery of a specified number of solid objects for chosen purposes.

Description

The The invention relates to an apparatus and a method for controlled Dosing a freely selectable Number of lumpy solids such as. Tablets.

In Pharmaceutical practice are small-sized excipients such as Pellets or microtablets known, the same dimensions in the space dimensions. A single dose for one Patients consists of several of these excipients. As a rule, one of the average single dose will be appropriate Amount of excipients Packed by the pharmaceutical manufacturer in hard capsules. An individual Dosage adapted to the needs of the patient, is not or only by filling the capsules and counting the excipients possible.

at the usual Medicines tend to expose the individual doses about 5-50 individual excipients together. The safety of correct dosage by counting individual excipients is therefore doubtful.

Out WO 00/67695 is a dosing spoon known, with the predetermined by the holes on the spoon Number of excipients can be removed in one operation from a multi-dose container. The disadvantage of this invention is that for each dosage a corresponding measuring spoon needed becomes. Also, in practice, does not ensure that the loading process of the spoon Completely accomplished becomes. This is often the case, especially with almost empty tablet containers Case. In the application can furthermore excipients at the bottom of the spoon stick and erroneously be taken.

In DE 3632546 a cylindrical dosing dispenser is disclosed in which single microtablets are successively emptied from a storage vessel by continuous rotation of a metering disc. In this case, only one tablet per dispensing process is dispensed, so that even with this metering a count of the number required for the dosage of excipients remains necessary. Furthermore, due to the structural design of the metering high shear forces on the material to be metered, whereby a high abrasion and damage of the metering occur.

Of the Invention is based on the object, arbitrary, freely selectable quantities of lumpy solids Safe by a single handle, avoiding mechanical damage at the dosing, at the same time measure and targeted from a storage container to to let.

These The object becomes in connection with the preamble of the patent claim 1 according to the invention the characterizing features of claim 1 solved.

In order to For the first time ever, a virtually unlimited dosage of drugs will be available in fixed small-sized excipients possible.

The Invention is helpful for the dosage of drugs contained in pellets, globules, mini- or microtablets are processed.

Special Benefits result from the use of the drug in children, which often require only fractions of an adult dose. By the use according to the invention a rotation limiting element becomes an unintentional overdose of the drug. For highly effective drugs or locally irritating drugs, there is another advantage that the user does not have to touch the excipients before taking them and the environment in the dosage of the drug is no longer contaminated.

One Another advantage lies in the greatest possible avoidance of shear loads of the dosing through the disclosed metering device.

Further Details of the invention are described in the drawing with reference to FIG illustrated embodiments described.

In 1 the dosing device according to the invention is shown in cross section.

The dosing device ( 1 ) consists of a cover element ( 2 ), a dosing disc ( 3 ), an adapter element ( 4 ), a rotation limiting element ( 5 ) and a metering wheel ( 6 ).

The dosing disc ( 3 ) is rotatable between the cover element ( 2 ) and the adapter element ( 4 ) arranged. The dosing disc ( 3 ) has a metering lever on the lateral surface ( 9 ). The dosing lever ( 9 ) is designed such that when turning the dosing disc ( 3 ) against the rotation limiting element ( 5 ) pushes.

In the dosing disc ( 3 ) are metering orifices ( 8th ) concentrically around the pivot point of the metering disk ( 3 ) arranged. The dosing openings ( 8th ) have the same geometric dimensions and are advantageously carried out slightly larger than the material to be dosed. According to a further advantageous embodiment, the metering orifices ( 8th ) circular. In a particularly advantageous embodiment of the invention, the rotation of the metering disk ( 3 ) counteract a spring element.

The adapter element ( 4 ) is positively or cohesively connected to the opening of a storage container ( 7 ) arranged.

The adapter element ( 4 ) has a receiving opening ( 11 ), which are aligned in the ejection direction one behind the other to a metering ( 8th ) is arranged.

According to a particularly advantageous embodiment of the invention, the adapter element ( 4 ) via an internal thread, so that the adapter element ( 4 ) with the corresponding external thread on the storage container ( 7 ) can be releasably connected.

The cover element ( 2 ) and the adapter element ( 4 ) are via a rotation limiting element ( 5 ) fixed against rotation against each other. The rotation limiting element ( 5 ) is connected to the cover element ( 2 ) and the adapter element ( 4 ) in each case positively, positively or materially connected.

According to a particularly advantageous embodiment of the invention, the rotation limiting element ( 5 ) non-positively or positively, detachable with the cover element ( 2 ) and adapter element ( 4 ), whereby the number of solids to be metered can be variably adjusted. In a further advantageous embodiment, a further rotation-limiting element can be fixed to the metering device, so that the rotational movement of the metering disk between the two rotation-limiting elements is limited. By the second, releasable rotation limiting element dosing is possible to a desired number dispensed dosing.

The cover element ( 2 ) has a dispensing opening ( 10 ), the discharge opening ( 10 ) in the cover element ( 2 ) is arranged such that the discharge opening ( 2 ) and a metering orifice ( 8th ) in the assembled state of the metering device ( 1 ) in the ejection direction are aligned one behind the other.

The metering wheel ( 6 ) is rotatable on the storage container ( 7 ) facing side of the adapter element ( 4 ) arranged. The metering wheel ( 6 ) has at least one spoke, wherein the distance of the spokes on the cross-sectional axis of the receiving opening ( 11 ) at least the diameter of the receiving opening ( 11 ) corresponds.

The enumeration of excipients is carried out by a preferably circular, rotatable metering disc ( 3 ) with metering orifices ( 8th ), which have a slightly larger diameter than the excipients. By the user of the dosing device ( 1 ) the dosing disc ( 8th ) by means of the metering lever ( 9 ) until, according to a particular embodiment of the invention, the desired number of excipients can be seen in a display. When retrieving the dosing disc ( 3 ) to the start position, the metering orifices filled with the excipient ( 8th ) via the discharge opening ( 10 ) of the cover element ( 2 ) completely emptied. If necessary, the dosing disc ( 3 ) by the corresponding design of the rotation limiting element ( 5 ) are blocked in a certain number of excipients, so that the preselected dose can not be exceeded.
