Abstract

A dosing system and a method for dosing a medium, having a dosing control unit (4), at least one exchangeable container (2) containing a medium to be dosed, and a dosing valve (3, 3′) that can be connected to the container (2), wherein at least one part of the dosing valve (3, 3′) that comes into contact with the medium is designed as an exchangeable system component (7, 10) and has a machine-readable code for identification purposes, wherein at least one container (2), as an exchangeable system component (2), has a machine-readable code for identification purposes, wherein the exchangeable parts (2, 7, 10, 19) that come into contact with the medium are designed as disposable parts, and wherein the dosing control unit (4) is connected with a communication unit (5) to read the codes, and wherein the communication unit (5) has a unique read connection (22) to each exchangeable system component (2, 7, 10, 19) or its code.

) that comes into contact with the medium is a first exchangeable system component (7, 10) and includes a first identification memory for storing only a first machine-readable code for first identification purposes, each of the first exchangeable system component (7, 10) and the at least one exchangeable container (2) being exchangeable independently of one another;

wherein the at least one exchangeable container (2) includes a second identification memory for storing only a second machine-readable code for second identification purposes,

wherein the at least one exchangeable container and the first exchangeable system component are disposable independently of one another,

wherein the dosing control unit (4) is connected to a communication unit (5) capable of reading the codes,

wherein the at least first part of the dosing valve (3, 2′

) that comes into contact with the medium is disposable independently of the at least one exchangeable container, and

wherein the communication unit (5) has a read connection (22) to the at least one exchangeable container and the first exchangeable system component for independently identifying the at least one exchangeable container and the first exchangeable system component based on the first machine-readable code or the second machine-readable code;

wherein the first machine-readable code and the second machine-readable code represents only information for verifying permissibility of using the at least one exchangeable container and the first exchangeable system component with one another.

2. The dosing system according to claim 1, wherein

the at least one exchangeable container comprises a plurality of exchangeable containers (2),

wherein the plurality of dosing valves (3, 3′

) each having a first part suitable for contacting the medium, each connected to one of the plurality of exchangeable containers (2),

the plurality of exchangeable containers are each fixedly connected to the dosing valve (3, 3′

) associated to each container,

wherein each of the plurality of the exchangeable containers (2) or the first part of the dosing, valves (3,3′

) that come into contact with the medium, have only one machine- readable code for identification purposes,

wherein the plurality of containers and the first part of the dosing valve that comes into contact with the medium are disposable parts,

wherein the dosing control unit (4) is connected to a communication unit (5) for reading data codes, and

wherein the communication unit (5) has a read connection (22) to each of the plurality of the exchangeable containers (2) or the part of the dosing valves or the data codes.

3. The dosing system according to claim 1, further comprising

a pump (18) that includes a part which contacts the medium for transporting the medium and which part is an exchangeable system component and which includes a third machine-readable code.

4. The dosing system according to claim 1, wherein the dosing control unit (4) is connected to a system component memory (21) for storing at least the first machine-readable code and the second machine readable code.

5. The dosing, system according to claim 4, wherein dosing information is stored in the system component memory (21).

6. The dosing system according to claim 1, wherein the first machine-readable code and the second machine-readable code are bar codes on a label.

7. The dosing system according to claim 6, wherein the coding comprises identification codes stored in the first identification memory and the second identification memory (6).

8. The dosing system according to claim 7, wherein the first and second identification memory (6) containing the codes are writable via the communication unit (5).

9. The dosing system according to claim 3, wherein each identification memory (6) is an EEPROM or a transponder

10. The dosing, system according to claim 3, wherein the parts that contact the medium are sterilizable.

11. The dosing system according to claim 3, wherein the dosing valve (3, 3′

) comprises

a second valve part which is disposable and which is integrated into a tubing system, and

a reusable actuator (8) that can he controlled by the dosing control unit (4).

12. The dosing system according to claim 11, wherein dosing valve (3) is a pinch valve, flap valve, slide valve or diaphragm valve,

13. The dosing, system according to claim 12, wherein the pump (18) comprises

a second pump part (19) which is disposable and which is integrated into the tubing system (14), and

a reusable drive (20) which is controlled by the dosing control unit (4).

14. The dosing system according to claim 13, wherein the second pump part (19) includes an exchangeable rube of a peristaltic pump, or an exchangeable pump head of a centrifugal or piston pump or of a diaphragm pump.

15. The dosing system according, to claim 14, further comprising

a target container (15) connected to the at least one exchangeable container, dosing sensors,

a scale (9, 9′

) for monitoring the container by weight (2), and/or a second scale (17) for monitoring the weight of the target container (15).

16. A method for dosing a medium using the dosing system (1, 1′

, 1″

, 1′

″

) according to claim 1, the method comprising the steps of

supplying the medium to a target container (15) via the dosing valve (3, 3′

) connected to the at least one exchangeable container (2),

controlling the dosing control unit (4), wherein prior to starting the dosing process, machine-readable codes arranged on the at least one exchangeable container (2) or the first exchangeable system component (7, 10) that come into contact with the medium and that are designed as disposable parts, are read by the communication unit (5) via in each case unique read connections (22), and the permissibility of using the at least one exchangeable container (2) or the first exchangeable system component (7, 10) having the codes is verified by the dosing control unit (4) connected to the communication unit (5).
