Abstract

A portable medical apparatus including at least a sampling assembly for providing at least one sample of a fluid in an object, a detector for determining at least one parameter of the fluid, an injector for performing at least one injection of an injection medium, and which are operable independent of each other for improved self-treatment of diseases such as diabetes. The portable medical apparatus has a single common housing for these components and a switch for changing between the sampling mode, the determining mode, and the injection mode. The apparatus also includes an actuator means for individually actuating the other components. The apparatus is an all-in-one device that facilitates the medical treatment process for patients, medical professionals or others.
