First Claim
1. A drug delivery device comprising:
- a container,a first product and a second product, the device being configured to mix the first product and the second product with each other within the container for forming a drug mixture, the device being further configured for dispensing the drug mixture,a measuring unit,a control unit, anda mixing member,wherein the device is switchable from a first state, in which the first product and the second product are separated, into a second state, in which the first product and the second product are mixed, and wherein the mixing member is configured to exert a force onto the container in order to move the container to mix the first product and the second product with each other,wherein the measuring unit is configured to determine a value of a parameter of the drug mixture when the device is in the second state,wherein the control unit is configured to;
store a predetermined range of values of a parameter of the drug mixture,compare the determined value of the parameter of the drug mixture with the stored range of values, andwhen the value of the parameter is out of the predetermined range of values, cause the mixing member to exert the force onto the container such that the container holding the drug mixture is moved with respect to a housing for mixing the drug mixture.

13. A method for maintaining a predetermined property of a drug mixture to be dispensed from a drug delivery device, the drug delivery device comprising:
-
a container for the drug delivery device, the container being configured to hold the drug mixture, a measuring unit configured to determine a value of a parameter of the drug mixture, and a control unit configured to store a predetermined range of values of a parameter of the drug mixture, compare the determined value of the parameter of the drug mixture with the stored range of values, and when the value of the parameter is out of the predetermined range of values, cause force to be exerted onto the container such that the container holding the drug mixture is moved with respect to a housing for mixing the drug mixture, the method comprising the following steps; determining a value of a parameter of the drug mixture and determining whether said value lies within a predetermined range of values, and exerting force onto the container to move the container and the drug mixture if the value is out of the predetermined range of values.
