Apparatus for analyzing body fluids
First Claim
1. An apparatus for analyzing body fluids from a living subject comprising:
- fluid sampling means continuously in fluid communication with to a living subject for drawing a fluid therefrom for the duration of a fluid sampling procedure;
sensor means for analyzing said fluid;
a cassette magazine containing a plurality of disposable cassettes;
transfer means for successively bringing cassettes individually from said cassette magazine into and out of fluid communication with said fluid sampling means for allowing said fluid to flow into a cassette while in fluid communication with said fluid sampling means for analysis of the fluid in the cassette by said sensor means; and
control means for controlling said transfer means to successively bring said cassettes individually into and out of fluid communication with said fluid sampling means at a programmable rate.

Abstract
An arrangement for analyzing body fluids drawn from a living subject has a fluid sample station connectable to the subject for drawing fluid from the subject, a disposable cassette connectable to the fluid sample station for receiving a fluid sample to be analyzed, a sensor unit for analyzing the fluid sample, a cassette store in which a plurality of disposable cassettes are storable and a transfer system for bringing cassettes in the cassette store, one by one, into operative connection with the fluid sample station. A control unit controls the transfer system to bring the respective cassettes into connection with the fluid sample station at a programmable rate.
