ABSTRACT:
A method and apparatus for the administration of medical injections. After insertion of an injection needle into a patient, a negative pressure differential is applied to the exposed end of the injection needle so that if the injection needle has been inserted into any artery or a vein, blood will be drawn up into the needle. A transparent window allows the person administering the injection to observe whether any blood has been drawn into the needle.
