"Building one space station for everyone was and is insane: we should have built a dozen."
- Larry Niven

Diagnostic Sleeve  
  Worn on one arm, it diagnoses and adminsters medications.  

I thought this was an interesting variation on the automatic bloodpressure cuffs that are becoming more common. Instead of just taking a bloodpressure, the diagnostic sleeve probably takes more data, and will also perform medical interventions if necessary.

Bury's vision swam. He pulled the diagnostic sleeve out of his chair arm and inserted his arm, hoping mobody would notice. Orange dots blinked, and he felt the coolness of a tranquilizer injection.
