Abstract: A system (20) for establishing wireless communication between at least one medical device (2) having a predefined unique identification (ID) and at least one communication unit (4, 6, 8) includes a communication unit (4, 6, 8) provided with a primary two-way wireless data communication interface (52) including systems for wirelessly performing primary two-way data communication, including receiving and transmitting information (10, 14). The system (20) includes systems for securing that the primary two-way wireless data communication can be carried out if and only if the communication unit (4, 6, 8) positively and in advance has identified the predefined unique identification (ID) of the medical device (2). The system (20) includes secondary one-way wireless communication systems (24, 24?, 28, 30) configured for carrying out identification of the predefined unique identification (ID) of the medical device (2) through secondary wireless communication.

Abstract: A disposable cassette (1) for storing and delivering a medical drug, the cassette (1) comprising a cartridge (7) containing the medical drug, a waste reservoir (8) arranged to receive waste liquid and/or gas, an injection needle (9)arranged to deliver the medical drug, and a valve block (10) being movable between a first position and a second position. The first position establishes a fluid passage between the cartridge (7) and the waste reservoir (8), while preventing fluid flow from the cartridge (7) to the injection needle (9), and the second position establishes a fluid passage between the cartridge (7) and the injection needle (9), while preventing fluid flow from the cartridge (7) to the waste reservoir (8).

Abstract: A medical cartridge containing multiple doses of a medical drug is disclosed. An outlet end is arranged to be connected to an injection needle for delivering the medical drug. The medical cartridge comprises a one way valve arranged in an interior part of the medical cartridge at a position near the outlet end. The one way valve allows a fluid flow from the interior of the medical cartridge towards the outlet end, but prevents a fluid flow from the outlet end towards the interior of the medical cartridge. Thereby the risk of contamination of the medical drug remaining in the cartridge is minimized.
