A hypodermic needle adapted to emit light from its distal end to facilitate venopuncture under subdued lighting conditions. The needle is used in conjunction with a portable light source, such as a battery handle and lamp, and includes a bundle of optical fibers that transmits light from the lamp to the distal end of the needle. A flexible catheter is releasably mounted on the needle and is adapted to be inserted in the vein after the needle has punctured same and thereafter the needle can be withdrawn from the catheter. |
