Abstract
A device for drawing spinal fluid from a body part or injecting medication into the body part is disclosed. The device may include one or more measurement features (markings) that indicate the subcutaneous depth of the device as well as confirm placement and orientation of the spinal fluid withdrawing or medication injecting end of the device in the body part. The device may include a trocar and a cannula having a patient end, a non-patient end, an outer surface, and a central passage adapted to receive said trocar. One or more windows may be provided in or on the cannula, said windows extending from the outer surface of the cannula to the central passage. The windows may be spaced from the patient end of the cannula and from each other along a specific longitudinal axis of the cannula by a predetermined distance, such as 10 millimeters.
