Drug delivery device and method for a drug delivery device
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, 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 device comprises a measuring unit comprising at least one sensor, the measuring unit being configured to determine a value of a parameter of the drug mixture when the device is in the second state, wherein the sensor detects the opacity, cloudiness, or light scattering, reflection or transmission of the drug mixture as the parameter that exists after mixing the first product and the second product with each other that is indicative for a mixing property of the drug mixture.

Abstract
A drug delivery device is provided comprising a container, a first product and a second product. The device is configured to mix the first product and the second product with each other within the container for forming a drug mixture. The device is further configured for dispensing the drug mixture. The device comprises a mixing member. 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. 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. Furthermore, a method for maintaining a predetermined property of a drug mixture to be dispensed from a drug delivery device is provided.

15. 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 measuring unit comprising at least one sensor, wherein the measuring unit is configured to determine a value of a parameter of the drug mixture, the method comprising the following steps:
-
providing a container for the drug delivery device, the container being configured to hold the drug mixture, sensing the parameter with the at least one sensor, where the parameter detected is the opacity, cloudiness, or light scattering, reflection or transmission of the drug mixture that exists after first mixing a first product and a second product to form the drug mixture, based on collected information from the at least one sensor, determining a value of a parameter of the drug mixture, wherein the parameter is indicative for a mixing property of the drug mixture, 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.
