Abstract

The McRae blood-taking needle is a very useful article. It is hard to clean, however, and rusts easily. In an attempt to overcome these slight disadvantages, I devised a modification of it in the form of the adapter here illustrated.1

The adapter is made of a nonrusting material, and its caliber is so large that it is easily cleaned. Any Luer needle of the desired size may be used on it, and the suction end takes a Luer observation tube or rubber tubing without the interposition of the observation tube.
