Abstract
For determining blood pressure a cannula, insertable through a needle into the bloodstream, locates a flaccid, relaxed wall directly in the bloodstream. The relaxed nature of this wall allows direct transmission of the blood pressure to a neutral liquid in the cannula. The cannula transmits this liquid pressure out of the blood vessel to the remote pressure responsive indicator. Thus blood pressure can be directly measured without need of administering anticoagulants to maintain pressure-transmitting conditions.
