<p>Intermittent feed of dialysis fluid through a microdialysis catheter (A) is effected by a portable, battery-operated pump (B) in a controlled amount which corresponds to the active volume of the catheter (A) with no surplus and which is in the order generally of some tenths of a microliter. This provides the best sample concentration and a long battery life span, and a pump having small dimensions and capable of being carried firmly on the body of a patient.</p> |
