Abstract
The present invention concerns a system for determining the concentration of at least one analyte in a body fluid. The system has a first member and at least a second member of which at least one has a recess on its surface and the members are joined together in such a manner that the recess is closed by a surface of the other member to form a channel. The first and/or second member is composed at least partially of a membrane which is located either in the region of the recess or on the part of the other member that is opposite to the recess such that substances can be taken up from the surrounding fluid by means of the membrane. The system additionally has a sensor which can be used to determine the concentration of an analyte in the channel. Furthermore the system has at least one integrated reservoir which is connected to the channel.
