Claim:
A portable hand-held analytical device for analysis of a medically significant component of a sample, said device comprising: an analytical measuring unit, a housing comprising a loading opening for receiving a replaceable drum cartridge, which can comprise analytical consumables and comprises at least one removal opening adapted to be disposed at a front face of the drum cartridge, a pushing part movably disposed in the housing and operable to contact and push a drum cartridge into a working position, the pushing part comprising a spring, a lid for closing the loading opening, the lid comprising a positioning element that projects into the inside of the housing when the lid is closed, a bearing for the drum cartridge facilitating a rotation of the drum cartridge about the geometric longitudinal axis of the drum cartridge, and a removal facility for removing the analytical consumables from the drum cartridge, said housing comprising on one outer side a dispensing opening through which a consumable can be pushed by means of the removal facility, wherein closing the lid causes the positioning element to press against and effect a linear motion of the pushing part, the linear motion of the pushing part causing the pushing part to push the drum cartridge to a working position, in which it can be rotated about its geometric longitudinal axis.
