Abstract
A two-channel sampling needle is designed for withdrawing body fluids, such as blood or tissue fluid, has two essentially parallel cannulas, the first cannula being provided with an insertion needle which may be removed after the sampling needle has been introduced, its sharpened end projecting beyond the end of the first cannula. At the distal end of the sampling needle the second cannula has at least one connecting opening into the first cannula. A mounting part of the sampling needle is provided with fittings for the two cannulas and with a separate opening plugged by a flexible stopper for removal of the insertion needle.
