Abstract
The invention relates to a portable hand-held analytical device for analysis of a medically significant component of a sample, the device including a housing having a loading opening for receiving a replaceable drum cartridge containing analytical consumables, whereby the housing comprises on an outer side a dispensing opening through which the consumables can be pushed by means of a removal facility. The device includes a loading opening which is closeable by means of a lid, which upon closing effects a linear motion of a pushing part which moves the drum cartridge to a working position, in which it can be rotated about its geometric longitudinal axis.
Claims21
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.
A hand-held analytical device for analysis of a medically significant component of a sample, comprising:
- an analytical measuring unit;
- a housing comprising a dispensing opening and a loading opening, the loading opening configured to receive a replaceable drum cartridge having a removal opening through which an analytical consumable can move;
- a bearing for contacting one end of the drum cartridge, the bearing facilitating rotation of the drum cartridge about its longitudinal axis;
- a removal facility configured for moving the analytical consumable from the drum cartridge through the dispensing opening;
- 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;
- and
- wherein closing the lid causes the positioning element to press against and produce a longitudinal movement of the pushing part, which in turn causes the pushing part to move the drum cartridge into a working position.
