Definitions

  • the present invention relates to a drug package assembly apparatus, a conveyor belt, and a method of assembling drug packages.
  • a pharmacist would often collect drug packages (e.g., resealable bags, bottles and boxes) for a prescription from different sources (e.g., boxes on a shelf) into a container. Once all drug packages for the prescription are collected, the container would be made available for collection by, for example, a patient for whom the prescription is made.
  • drug packages e.g., resealable bags, bottles and boxes
  • the container would be made available for collection by, for example, a patient for whom the prescription is made.
  • fulfilment of the prescription by the pharmacist may be laborious and time-consuming.
  • a drug package assembly apparatus comprising: a plurality of collection receptacles associated with respective prescriptions; a plurality of intermediate collection stations arranged to receive and hold drug packages delivered from respective sources in association with the prescriptions; and a transfer mechanism operable to transfer the held drug packages from the intermediate collection stations to at least one of the collection receptacles based on the prescriptions.
  • the described embodiment is particularly advantageous. Drug packages received and held by the intermediate collection stations are transferred to the collection receptacles by the transfer mechanism according to prescriptions associated with the collection receptacles. Instead of a pharmacist moving about to collect and assemble drug packages, drug packages are delivered by the respective sources to the apparatus for assembly by the apparatus.
  • the apparatus thus improves efficiency of dispensing drug packages, particularly in a scenario with a large number of prescriptions to be fulfilled.
  • the use of the intermediate collection stations also improves throughput and productivity of dispensing the drug packages via the collection receptacles.
  • At least one of the intermediate collection stations and the transfer mechanism includes a conveyor belt.
  • the conveyor belt may have a contact surface with a plurality of protrusions arranged along a plurality of longitudinal axes, wherein the protrusions are spacedly arranged in each axis, and the protrusions in each axis are spaced apart from those in an adjacent one of the axes.
  • the protrusions may be arranged in a grid formation.
  • each protrusion satisfies at least one of the relationships:
  • ‘d’ represents a distance between the protrusion and a neighbouring protrusion
  • ‘r’ represents a radius of a cylindrical portion of a Tollable object to be conveyed by the conveyor belt
  • ‘h’ represents a height of the protrusion
  • ⁇ ’ represents an angle formed by a radial line, which extends through the radius point of the cylindrical portion and a point of contact between the cylindrical portion and the protrusion, with respect to the contact surface
  • ‘L’ represents a length of the protrusion in a conveyance direction of the conveyor belt
  • ‘C’ represents an outer circumference of a pulley associated with the conveyor belt. Rolling movements of cylindrical objects on the conveyor belt due to inertia can thus be reduced or restricted by the protrusions.
  • the conveyor belt may be provided with at least one of: a pair of wall members arranged to restrict movement of drug packages on the conveyor belt past lateral sides of the conveyor belt; and a gate member arranged at one end of the conveyor belt, and moveable between open and closed positions to permit and block passage of drug packages therethrough, respectively.
  • Drug packages on the conveyor belt may, depending on placement, be susceptible to lateral movements (movements in a lateral direction).
  • the wall members are useful in preventing drug packages from thus falling off via the lateral sides of the conveyor belt.
  • the gate member is useful in selectively allowing passage of drug packages through said one end of the conveyor belt. In particular, the gate member is useful in preventing unintentional passage of drug packages via said one end of the conveyor belt, which may occur due to inertial movements of the drug packages.
  • the gate member is formed with recesses matching the protrusions in position and shape. This configuration reduces the width of a gap between the gate member and the contact surface of the conveyor belt when the gate member is at the closed position, and is useful in reducing the chance of smaller drug packages unintentionally passing through the gate member via the gap.
  • the transfer mechanism may include a pusher operable to push a drug package into a corresponding one of the receptacles via an opening associated with the receptacle.
  • the associated opening partially defines an edge portion arranged at an oblique angle with respect to a vertical axis of the opening, wherein the pusher is inclined at the same oblique angle.
  • the pusher is operable to push the stuck drug package into the corresponding collection receptacle via the associated opening, ensuring uninterrupted operation of the apparatus.
  • Each collection receptacle may be provided with at least one of: a lockable door, which is configured to permit access to the respective collection receptacle if the respective collection receptacle is determined to contain all drug packages associated to the respective collection receptacle; a sensor operable to detect presence of a removable container for drug packages in the respective collection receptacle; and a light indicator operable to indicate a status of the respective receptacle for collection.
  • the lockable door ensures that corresponding collection receptacle is not accessed prematurely.
  • the sensor is useful in that, in the event where a container is improperly placed in, or missing from, a collection receptacle, the collection receptacle can be excluded from association with a prescription or a portion of the prescription until rectification takes place.
  • the light indicator can operate in association with the lockable door to indicate the status of a corresponding collection receptacle for drug package collection.
  • each intermediate collection station is provided with a sensor arranged to detect presence of a drug package held at the respective intermediate collection station.
  • the sensor can detect presence or arrival of these drug packages, ensuring that only these drug packages are held for collection by the transfer mechanism. The sensor is thus useful in preventing drug packages belonging to different prescriptions being collected and transferred by the transfer mechanism.
  • the transfer mechanism may include an image capturing device for capturing an image of a visual representation of identification information associated with each collection receptacle and to be association with the respective prescription.
  • This arrangement allows a collection receptacle to be associated with new identification information, such as a barcode, for fulfilment of another prescription, upon fulfilment of a prescription and collection of drug packages associated with the fulfilled prescription from the respective collection receptacle.
  • This arrangement eliminates or reduces the need for the identification information to be manually entered upon each collection of drug packages by a user, and works in association with the sensor of the collection receptacle, if implemented, to ensure that drug packages are dispensed into the right receptacles.
  • the system is modular.
  • the system if implemented to be modular, allows the drug dispensing or assembling capacity to be adjusted to meet changing needs. Different possible configurations of the modular system are exemplified in the described embodiment.
  • the transfer mechanism may be controlled to perform the method including: collecting a first drug package held by one of the collection stations; if a second drug package related to the first drug package satisfies a delay condition, providing the collected first drug package to one of the collection receptacles corresponding to the first drug package, and collecting and providing an intermediate drug package to another one of the collection receptacles corresponding to the intermediate drug package, the intermediate drug package being unrelated to the first drug package; and collecting and providing the second drug package to the collection receptacle of the first drug package.
  • This arrangement is useful in achieving a higher drug dispensing efficiency.
  • the collected second drug package may be provided to the collection receptacle of the first drug package together with the collected first drug package.
  • the delay condition can be configured according to implementation of the apparatus. In the described embodiment, the delay condition is the second drug package being unavailable for collection at the time of collection of the first drug package. Alternatively, where the delay condition is otherwise dependent on the availability of the second drug package for collection, the delay condition may be the second drug package being expected to arrive at the corresponding intermediate collection station within a pre-set or predetermined duration of time. In another arrangement, a position of the intermediate drug station of the second drug package relative to those of the collected first drug package and the intermediate drug package may also form the delay condition, either partially or wholly. Preferably, the intermediate drug package and the second drug package may be collected from different collection stations. At least one of the intermediate drug package and the second drug package may be collected from a collection station different from that of the first drug package.
  • drug packages held by each individual one of the collection stations, at any given time belong to no more than one prescription.
  • the drug packages may include bottles, blister packs, boxes or bags containing medical items.
  • the apparatus may further comprise a control device arranged to: receive the respective prescriptions; control the sources to dispatch the drug packages based on the prescriptions for delivery to the intermediate collection stations; and operate the transfer mechanism to transfer the drug packages held by the intermediate collection stations to the collection receptacles.
  • a control device arranged to: receive the respective prescriptions; control the sources to dispatch the drug packages based on the prescriptions for delivery to the intermediate collection stations; and operate the transfer mechanism to transfer the drug packages held by the intermediate collection stations to the collection receptacles.
