Abstract

A system for automatically filling tablets into tablet containers comprising at least one tablet compartment for receiving tablets comprises:

reception means (30) for receiving a patient order containing a patient identification (PAT-ID) and at least one prescription comprising prescription data (REZ) regarding the types of tablets to be taken by the patient and instructions for taking said tablets;

allocation means (40) for allocating the prescription data (REZ) and patient identification (PAT-ID) to respective tablet containers (1);

at least one automatic tablet dispenser (50) containing supplies of a plurality of tablet types for automatically filling at least one tablet compartment of a respective tablet container, wherein the allocation means (40) or the automatic tablet dispenser (50) is/are designed for determining, from the prescription data (REZ), the number of tablets of the respective types of tablets to be taken by a patient at certain times and for allocating a tablet compartment (2) of a tablet container (1) to each determined time for taking the tablets, and the automatic tablet dispenser (50) is designed for filling the tablets thus determined for each determined time for taking them into the tablet compartment (2) of the respective tablet container (1), which compartment has been allocated.

wherein the number of tablets of the respective types of tablets to be taken by a patient at certain times is determined from the prescription data and a tablet compartment of a tablet container is allocated to each determined time for taking the tablets and the tablets thus determined are filled for each determined time for taking them into the respective tablet compartment that has been allocated;

sealing and delivering the filled tablet containers.

2. A tablet filling method according to claim 1, wherein the allocation of prescription data and patient identification to respective tablet containers comprises the transmission of prescription data and patient identification to one or several information carriers and the allocation of a respective information carrier to one tablet container at a time.

3. A tablet filling method according to claim 2, wherein an electronic data carrier, which preferably is writable and readable in a non-contact manner, or a printable substrate such as a bar-code label is provided as an information carrier.

4. A tablet filling method according to claim 2, wherein the automatic filling of at least one tablet compartment of a respective tablet container by at least one automatic tablet dispenser comprises conveying the tablet containers and the information carriers allocated thereto jointly through the at least one automatic tablet dispenser;

reading out the prescription data stored on the information carrier by the respective automatic tablet dispenser;

checking by means of the respective automatic tablet dispenser as to whether the supplies of tablet types stored in it correspond to one of the tablet types contained in the prescription data and, in case of correspondence,

determining the number of tablets of the respective types of tablets to be taken by the patient at certain times and allocating a tablet compartment to each determined time for taking the tablets, and

filling the determined tablets into the respective tablet compartment that has been allocated.

5. A tablet filling method according to claim 1, wherein upon receiving the patient order, a plausibility check of the prescription data regarding a possible overdosage and the mutual compatibility between tablet types is carried out and, in case an overdosage or an incompatibility is detected, the patient order is rejected.

6. A tablet filling method according to claim 1, wherein the tablet containers are provided with at least one of information derived from the prescription data, instructions for taking the tablets, and the patient identification, by at least one of imprinting and labeling the tablet container.

7. A tablet filling method according to claim 1, wherein if errors occur during the implementation of the tablet filling process for a tablet container, the tablet filling process is stopped and the tablet container is eliminated.

8. A tablet filling method according to claim 24, wherein if errors occur during the implementation of the tablet filling process for a tablet container, error identifications are written onto the information carrier allocated to said tablet container and tablet containers marked with error identifications in this way are eliminated during the delivery.

9. A tablet filling method according to claim 8, wherein prior to each processing step of the tablet filling process, it is checked for each tablet container as to whether the information carrier allocated to said tablet container contains an error identification and, upon detection of such an error identification, the respective processing step is not carried out.

10. A tablet filling method according to claim 1, wherein the delivery of the filled tablet containers comprises collecting all tablet containers belonging to a respective patient order.

24. A tablet filling method according to claim 2, wherein if errors occur during the implementation of the tablet filling process for a tablet container, the tablet filling process is stopped and the tablet container is eliminated.

25. A tablet filling method according to claim 3, wherein if errors occur during the implementation of the tablet filling process for a tablet container, the tablet filling process is stopped and the tablet container is eliminated.

26. A tablet filling method according to claim 25, wherein if errors occur during the implementation of the tablet filling process for a tablet container, error identifications are written onto the information carrier allocated to said tablet container and tablet containers marked with error identifications in this way are eliminated during the delivery.

27. A tablet filling method according to claim 26, wherein prior to each processing step of the tablet filling process, it is checked for each tablet container as to whether the information carrier allocated to said tablet container contains an error identification and, upon detection of such an error identification, the respective processing step is not carried out.

11. A system for automatically filling tablets into tablet containers comprising at least one tablet compartment for receiving tablets, the system comprising:
