Abstract

The present invention relates to a medication dispenser that comprises a first container for holding medication packages to be dispensed, and conveying means for conveying medication packages from the first container to an outlet of the medication dispenser, the conveying means comprising a first conveyor that is arranged in connection with the outlet and is capable of conveying a medication package in a first and a second conveying direction, so that a medication package can be conveyed to the outlet and retracted inside the medication dispenser. The first conveyor comprises two opposing belt conveyors between which a medication package is arranged to be conveyed, both of the belt conveyors comprising an endless belt and a plurality of rollers around which the endless belt is arranged. The invention also relates to a method for dispensing medications.

Claims

1. A medication dispenser, comprising:

a first container for holding medication packages to be dispensed, and

conveying means for conveying medication packages from the first container to an outlet of the medication dispenser, the conveying means comprising a first conveyor arranged in connection with the outlet and being capable of conveying a medication package in a first and a second conveying direction, so that a medication package can be conveyed to the outlet and retracted inside the medication dispenser;

wherein the first conveyor comprises two opposing belt conveyors between which a medication package is arranged to be conveyed, both of the belt conveyors comprising an endless belt and a plurality of rollers around which the endless belt is arranged, and

wherein the first conveyor is arranged to be turnable about an axis between a first and a second position, wherein at the first position the first conveyor is capable of receiving a medication package from a second conveyor of the conveying means.

2. The medication dispenser according to claim 1, wherein a diameter of the rollers of the belt conveyors is larger at the inlet end than at the outlet end of the first conveyor.

3. The medication dispenser according to claim 1, wherein at the second position the first conveyor is capable of conveying the medication package to a second container of the medication dispenser.

4. The medication dispenser according to claim 1, wherein a distance between the belt conveyors is adaptive according to the thickness of the medication package.

5. The medication dispenser according to claim 1, wherein the belt conveyors are connected to each other using a plurality of springs.

6. The medication dispenser according to claim 1, wherein the medication dispenser comprises a first detector arranged in connection with the outlet for detecting the presence of a medication package at the outlet.

7. The medication dispenser according to claim 1, wherein the medication dispenser comprises a second detector arranged below the first conveyor for detecting medication packages in the second container.

8. The medication dispenser according to claim 1, wherein the medication dispenser comprises a third detector arranged above the first conveyor for monitoring the conveyance of medication packages.

9. The medication dispenser according to claim 1, wherein the medication dispenser comprises a reader arranged in connection with the conveying means for reading the taking time of medications from a label of a medication package.

10. A method for dispensing medications using a medication dispenser, said medication dispenser comprising:

a first container for holding medication packages to be dispensed, and

conveying means for conveying medication packages from the first container to an outlet of the medication dispenser, the conveying means comprising a first conveyor arranged in connection with the outlet and being capable of conveying a medication package in a first and a second conveying direction, so that a medication package can be conveyed to the outlet and retracted inside the medication dispenser;

wherein the first conveyor comprises two opposing belt conveyors between which a medication package is arranged to be conveyed, both of the belt conveyors comprising an endless belt and a plurality of rollers around which the endless belt is arranged,

wherein the first conveyor is arranged to be turnable about an axis between a first and a second position, wherein at the first position the first conveyor is capable of receiving a medication package from a second conveyor of the conveying means, and

wherein the method comprises;

setting a time window for the taking of medications contained in a medication package,

notifying a patient of the start of the time window, and

if the patient acknowledges the notification before the end of the time window;

conveying the medication package to an outlet of the medication dispenser, and

if the medication package is at the outlet after a predetermined time period, retracting the medication package inside the medication dispenser.

11. The method according to claim 10, wherein the method comprises, if the medication package is in the medication dispenser after the time window has ended, conveying the medication package to a second container of the medication dispenser.

12. The method according to claim 10, wherein the step of setting the time window for the taking of the medications contained in the medication package comprises:

reading a taking time of the medications from a label of the medication package, and

selecting the time window to consist of the taking time, a first predetermined time interval preceding the taking time, and a second predetermined time interval following the taking time.

13. The method according to claim 10, wherein the method comprises detecting a time of taking the medication package from the outlet.

14. The method according to claim 13, wherein the method comprises changing the first and/or the second predetermined time interval based on the detected time of taking the medication package.
