ABSTRACT:
The invention is related to a cannula used in medication for infusing liquid and/or giving a medicine injection into a vein, which cannula comprises a hollow body, an indication chamber part that, equipped with a steel needle, is coupled to it, a catheter, and a rear plug. To achieve a cannula that would be more advantageous to handle, the body and the indication chamber part, coupled to each other, are essentially at right angles to each other, in such a way that the indication chamber in said chamber part is in an essentially vertical position, having in its upper part an indicating device, and the chamber part is shaped to be held between the thumb and the forefinger.
