A Simple Quantitative Method for Intravenous Injection of Small Volumes of Fluid

Abstract

Two glass syringes and a metal 3-way stopcock are used. The soln. to be injected is pipetted into the upright syringe barrel and after injn. the barrel can be filled with saline and washed through as often as desired. Advantages claimed are: (1) measurement from a pipette is more accurate than from a syringe; (2) several solns. can be measured and given in a single injn. and (3) rinsing out is done with saline instead of with blood.
