Disclosed herein are hand-held medical devices, such as blood glucose meters, that include a housing with a cassette compartment for receiving an exchangeable test tape cassette, a drive assembly comprising an electric motor and a gear arrangement adapted for rotating a tape spool of the test tape cassette, where the gear arrangement has a worm drive in which a worm meshes with a worm wheel and a multistage speed-reducing unit comprising a plurality of spur gears arranged between the worm wheel and an output gear that can be directly coupled to the tape spool.

Hand-held medical device

A method and system is disclosed for reducing slurry usage in a chemical mechanical polishing operation utilizing at least one polishing pad thereof. Slurry can be intermittently supplied to a chemical mechanical polishing device. The slurry is generally flushed so that a portion of said slurry is trapped in a plurality of pores of at least one polishing pad associated with said chemical mechanical polishing device, wherein only a minimum amount of said slurry necessary is utilized to perform said chemical mechanical polishing operation, thereby reducing slurry usage and maintaining a consistent level of slurry removal rate performance and a decrease in particle defects thereof. The present invention thus discloses a method and system for intermittently delivering slurry to a chemical mechanical polishing device in a manner that significantly conserves slurry usage.
