Abstract: The invention relates to administration systems and to methods which can improve the safety of administration systems, more particularly the safety of an infusion system, in which system it is checked, when the medication container is exchanged, whether the new container is appropriate for the system. A system of this type consists of an administration device (1), a mobile communication device (3) and servers (5). When a reservoir (2) or the administration device (1) is replaced, an image of information (2a) is captured by means of a camera (3a) of the communication device (3). As a result of evaluation of the information (2a) by means of a software application, functions of the administration device (1) are activated or not.

Abstract: A patient device includes a case and a user interface for interaction between a patient and the patient device. The case may include a projection unit which projects information onto a surface separate from the case. The user interface may include a display unit for displaying information relating to the patient device integrated into the case and an additional display unit for displaying information relating to the patient device, which is external to the case. The externally provided display unit may be coupled to the case such that it can be at least one of folded, tilted, pulled out or unrolled relative to the case.

Abstract: An insulin pump and an infusion set adapter having a membrane which can be acted upon by a liquid flow path associated with the pump, wherein the pump comprises a sensor by which a change in shape or location of at least a portion of the membrane caused by a change in the liquid pressure in the flow path can be detected in a contact-free manner to identify an occlusion in the flow path.

Abstract: A container for receiving liquids with different concentrations of an active substance that is to be administered or dosed, wherein the container includes a hollow body and a displaceable element for expelling the liquid is located for longitudinal movement in the hollow body, and wherein the cross-sectional surface area of the hollow body is inversely proportional to the concentration of the substance, such that, with identical strokes or longitudinal movements of the displaceable element, the discharged amount of active substance remains independent of the concentration of the substance in the container.

Abstract: A patient device including a case and a user interface for interaction between a patient and the patient device, wherein at least a part of the user interface is separable from the case and may be used or recognized by the patient.

Abstract: A device for automated subcutaneous delivery of insulin into a patient's body, wherein the device includes an infusion cannula for subcutaneous introduction of the insulin into the body, an insulin reservoir having an amount of insulin which is non-fatal for a person on short-duration subcutaneous administration, and an automated conveying device for conveying the insulin from the reservoir to the infusion cannula which, after manual actuation by the patient, starts automatically conveying the insulin, after a delay of from four to eight hours, and conveys the complete amount of insulin in the reservoir to the infusion cannula within a period not exceeding four hours. Methods of making and using the device are encompassed.
