It was not until 1954, with the need for massive syringe distribution of Dr.

Alexander Wood and immediately efforts were made to improve the design. The first hypodermic needle was first used by Dr. Specifically, there is some data to suggest that disease transmission for people who inject drugs and carry Hepatitis C virus can be reduced with the use of low dead space syringes. However, there are problems associated with the dead space in syringes: medication waste, disease transmission, and inaccurate dosing. Д¬onventional high dead space syringes have existed since the mass production of plastic syringes with removable needles in 1961. This space can be as high as 84 micro liters in conventional syringes. The term 'high dead space' refers to the fluid remaining within the needle and between the syringe hub and the plunger. ДЄs opposed to low dead space syringes, high dead space syringes are conventional needle and syringe designs.

Although no set standard for the designation of low dead space syringes and needles exists, it is the convention to designate any needle or syringe design that deviates from the standard needle and syringe design as low dead space if this new design yields a lower dead space. The difference between high and low dead space syringes is determined by the average quantity of fluid that cannot be expelled from the device. Example a low and high dead space syringe and the average fluid remaining after complete depression of the plunger.
