A storage container for drug portion storage and dispensing includes a housing having a cylindrical section and surrounding a receiving space for drug portions, a sorting mechanism rotatably disposed in the cylindrical section and including a main body, the main body forming a conical top surface and a main body casing surface, a plurality of projections formed on the main body casing surface, a plurality of channels, each channel formed between the projections, having a circumferential width and a radial depth, the projections further forming projection outer contours which define a cylindrical outer casing surface interrupted by the channels, and an axial projection having a height and an outer contour is arranged centrally on the conical top surface, wherein a maximum radial distance between the outer contour and the cylindrical outer casing surface is less than two times the circumferential width of one channel in the plurality of channels.
The present disclosure relates to a storage container for drugs and, in particular, to a storage container for a drug storage and dispensing station.
BACKGROUNDModern blister packing machines include multiple storage and dispensing stations. Such machines store a plurality of drug portions of a specific drug and dispense individual drug portions upon request. According to physician-prescribed drug administration times, drug portions stored in the storage and dispensing stations are gathered and blister packed on an individual basis for each patient.
A blister packing machine control device typically activates storage and dispensing stations for dispensing one or more drug portions. Upon activation by a blister packing machine control device, a drug portion stored in the storage container is separated by a sorting mechanism of the storage and dispensing station, and the drug portion is transferred to a dispensing opening of a guide apparatus of the blister packing machine. The drug portion is conveyed via the guide apparatus to a packing apparatus, which blister packs individual or multiple drug portions.
In many drug packaging settings, it is desirable to provide a storage container of a storage and dispensing station that reduces failure of drug portion dispensing.

The device according to the present disclosure and the method according to the present disclosure are described in greater detail below, with reference to the appended drawings, wherein:
The detailed description set forth below describes various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. Accordingly, dimensions are provided in regard to certain aspects as non-limiting examples. However, it will be apparent to those skilled in the art that the subject technology may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology.
It is to be understood that the present disclosure includes examples of the subject technology and does not limit the scope of the appended claims. Various aspects of the subject technology will now be disclosed according to particular but non-limiting examples. Various embodiments described in the present disclosure may be carried out in different ways and variations, and in accordance with a desired application or implementation.
The typical sorting mechanism includes a rotor, and an outer circumference of the rotor is defined by a plurality of projections. Disposed between each pair of projections is a channel extending parallel to a rotational axis of the rotor. A width and a radial depth of these projections are adapted to the drug portion to be separated and dispensed. In such a channel, drug portions are situated only above one another, not next to one another. A given channel accommodates one or more drug portions, depending on the given channel's axial length.
A housing of the storage container, disposed above and/or around the sorting mechanism, defines a receiving space for drug portions. The sorting mechanism has a top surface which abuts the receiving space. The top surface may include a conical shape for the purpose of guiding the drug portions to channel openings. Such a design of the top surface prevents the drug portions from remaining stationary thereon, and prevents dispensing malfunctions.
The channel is rotated by a rotation of the sorting mechanism over a dispensing opening. The dispensable drug portion then falls from the channel through the dispensing opening due to gravity. Detents are provided over or inside the channel to prevent multiple drug portions from being dispensed at once.
Despite the conical design of the top surface of the sorting mechanism, drug portions nevertheless may become situated on the top surface such that the drug portion does not pass into a channel. This may result in a malfunction, wherein the drug portion is not dispensed following a rotation of the sorting mechanism.
A storage container according to the present disclosure reduces the occurrence of a drug dispensing malfunction, as described above, whereby one or more drug portions are not properly dispensed and/or arranged.
To reduce errors when assembling multiple drug portions, it is advantageous to detect the actual dispensing of a drug portion. If a malfunction, including a failure to dispense a drug portion, is detected, another dispensing procedure must be performed. The required use of another dispensing method delays the assembly of multiple drug portions and reduces the overall speed and efficiency of a blister packing machine.
The present disclosure provides a storage container for storage and dispensing stations with an increased drug portion dispensing rate, and thus a reduced malfunction rate.
The storage container according to the present disclosure includes a housing having a cylindrical section and further includes a receiving space for drug portions. The storage container of the present disclosure also includes a sorting mechanism having a main body rotatably disposed within the cylindrical section of the housing.
The main body features a conical top surface and a main body casing surface on which a plurality of projections is formed. These projections define channels with a circumferential width KB and a radial depth KT, and the projection outer contours of the projections define a cylindrical outer casing surface interrupted by the channels.
According to the present disclosure, an axial projection with a height VH and an outer contour VAK is arranged centrally on the conical top surface, the axial projection being formed such that a maximum radial distance VAmax between outer contour VAK and the cylindrical outer casing surface is less than two times the circumferential width KB of one of the channels.
This configuration of the axial projection ensures that no two drug portions can lie flat radially next to one another on the top surface between outer contour VAK and the cylindrical section of the housing provided that the channel width is only slightly larger than the diameter of the largest drug.
Such an arrangement of two drug portions may be, particularly in the case of flat and round drug portions, a cause of a dispensing failure. In such a case, since a plurality of drug portions are arranged radially next to one another and exert a corresponding pressure on each other, the drug portions may not be able to enter a channel.
Due to the maximum radial distance between the outer contour VAK of the axial projection and the cylindrical outer casing surface being less than two times the circumferential width KB of one of the channels, a radial arrangement of two drug portions next to one another is prevented, thus avoiding a dispensing failure and allowing the drug portions to enter the channel unhindered.
If the criteria presented above are satisfied, an actual configuration of the axial projection depends on the particular shape of the drug portions to be sorted. The maximum radial distance between the outer contour of the axial projection and the cylindrical outer casing surface can be uniform, such as a cylindrical projection, or angle-dependent, such as a cylindrical projection with an angular bottom surface. Further, a cylindrical configuration of the projection may ease manufacturing costs and design difficulties related to the sorting mechanism.
In some embodiments, the axial projection includes a circular bottom surface. This allows an axial projection that, at least in some sections, is cylindrical or conical. In some embodiments, the axial projection is vertical in at least some sections. At a transition between the conical top surface and the axial projection, a curved transition can be formed that prevents the accumulation of dust and/or drug debris.
In some embodiments, the axial projection has a fully or partially projection conical top surface. Such a top surface prevents a drug portion from resting on the top surface, and instead directs the drug portion into the outer area of the sorting mechanism towards the openings of the channels.
As described above, an object of the axial projection is to prevent two drug portions from being situated radially next to one another. Depending on the exact form of the drug portions, the height of the axial projection may be only a fraction of the radius of the drug portion.
However, particularly if flat disc-shaped drug portions are to be sorted, the axial projection may have a height VH that is greater than one half of the radial depth KT of a channel. In this way, it is ensured that a drug portion does not slip at least partly onto the projections if appropriate pressure is applied from gravitational pressure from other drug portions, thus preventing a situation where two drug portions are arranged radially next to one another on the top surface and the projection.
The channels for receiving drug portions to be sorted may be open to the cylindrical outer casing surface of the sorting mechanism defined by the projection outer contours of the projections, and the radial channel depth is adapted to the maximum height of the drug portion.
In some embodiments, an annular space is formed above the projections. The annular space is bordered by the main body, and a radial width of the annular space corresponds to the radial channel depth.
The annular space facilitates the drug portions being oriented toward a channel entrance, as the drug portions can enter the annular space only in the orientation in which they can pass into the channels. An annular space of this type is particularly advantageous in the case of disc-shaped drug portions, since it may be otherwise difficult for the disc-shaped drug portions to pass from the conical top surface into the channels.
Disc-shaped drug portions may be oriented with their flat side facing the conical top surface. Whether or not the drug portions remain in a stationary manner on the top surface or the top surface rotates away from the overlying drug portions depends on a fill level of the storage container.
If the fill level is high, the pressure from the weight of the overlying drug portions is large, impeding movement into the channels or the annular space. To facilitate a tipping of the disc-shaped drug portions into the channels and/or annular space, embodiments of the present disclosure provide multiple elevations arranged on the conical top surface of the main body. Further, in some embodiments, these elevations are oriented radially with respect to the channels.
Turning to
The drive is arranged in a control unit (not shown) of the storage and dispensing station. The storage container 1 is realized, in exemplary embodiments, as a separate component from the control unit. Such an arrangement enables the storage container 1 to be removed from a blister packing machine by a handle 14, for refilling or filling the storage container 1 with drugs, while the control unit remains on the blister packing machine.
As shown in
In the figures, the sorting mechanism 30 is formed as a rotor and the channels 35 are arranged on the cylindrical outer casing surface 36. In some embodiments, the channels 35 can also be designed such that they do not open towards the cylindrical outer casing surface 36 of the sorting mechanism 30. In the exemplary embodiment shown, the projections 34 are formed to be integral with a main body 31. In one or more embodiments, the projections 34 can be formed as separate components from the main body 31 to enable the sorting mechanism 30 to be adapted for different drugs.
As shown in
As shown in
A storage and dispensing station including the storage container 1 according to embodiments of the present disclosure further includes components which regulate and/or control the dispensing and/or sorting of drugs. While the aforementioned drive for moving the sorting mechanism 30 and a sensor (not shown) for monitoring the dispensing of a drug portion may be arranged in the control unit, the drive and/or the sensor can also be part of the storage container 1 in some embodiments. In exemplary embodiments, the drive and/or the sensor are arranged in the lower section 12 of the storage container 1.
Turning to
The projections 34, in exemplary embodiments, are of a two-piece construction and surround a gap 45 in an axial direction. A detent section 18 of the detent 15 engages the gap 45. Detent 15 is arranged on the cylindrical section 11 of the housing 10, such that the detent section 18 is always arranged over the dispensing opening 21, as best shown in
The conical top surface 32 does not directly contact the surface of the projections 34, but rather the projections 34 are disposed below the conical top surface 32, thus forming above the projections 34 an annular space 38 defined by the main body 31 and the cylindrical section 11 of the housing 10. This annular space 38 facilitates the guiding of drug portions to the channels 35, as will be described in greater detail below.
As shown in
A plurality of elevations 39 is arranged on the conical top surface 32, which supports a tipping of a drug portion into a channel 35. This is shown in
In addition, the axial projection 40 is formed on the center of the conical top surface 32. The axial projection 40 includes a circular bottom surface 60 and a vertically oriented middle section 42. The vertically oriented middle section 42 forms the outer contour VAK/41 of the axial projection 40. The outer contour VAK/41 of the axial projection 40 determines the maximum radial distance VAmax between the outer contour VAK/41 and the cylindrical outer casing surface 36 defined by the projections 34. Depending on the configuration of the projections 34, the maximum radial distance VAmax can vary if the main body 31 has, for example, a square or any non-circular cross section, or the maximum radial distance VAmax can be uniform, as is the case with illustrated embodiments. In some embodiments, the axial projection 40 has a conical top surface 43.
In exemplary embodiments, the maximum radial distance VAmax specified above is less than two times the circumferential width KB of a channel 35. As show in
