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. Ĭonventional 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.

Īs 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. A low dead space syringe (LDSS) or low dead-volume syringe is a type of syringe with a design that seeks to limit dead space that exists between the syringe hub and needle.ĭifferences from high dead space syringes Example a low and high dead space syringe and the average fluid remaining after complete depression of the plunger.
