High Dead Space needles are those that retain some fluid in the barrel of the syringe after injecting. As such they are prone to gather blood from the injection site into the barrel of the syringe. This is the main transmission route of blood borne virus such as Hepatitis C. Low Dead Space Need leave very little space in the the barrel of the syringe post injection. Studies show this can equate to 40 times less fluid and 1,000 times less blood after injecting. This could be critical in reducing the likelihood of transmitting blood borne viruses amongst those who share injecting equipment. To read a review of this research produced by Findings, click here.
