Disposable syringe with needle, with parts labelled: plunger, barrel, needle adaptor, needle hub, needle bevel, needle shaft According to the World Health Organization, about 90% of the medical syringes are used to administer drugs, 5% for vaccinations and 5% for other uses such as blood transfusions.
The term "high dead space" refers to the fluid remaining within the needle and between the syringe hub and the plunger. This space can be as high as 84 micro liters in conventional syringes. [2] Conventional high dead space syringes have existed since the mass production of plastic syringes with removable needles in 1961. [3]
There are many types of safety syringes available on the market. [2] Auto Disable (AD) syringes are designed as a single use syringe, with an internal mechanism blocking the barrel once depressed so it cannot be depressed again. The other type of syringe with a re-use prevention feature is the breaking plunger syringe.
Injector pens remove some of the complications of syringes by allowing the pen to be "pushed" against the skin at a 90-degree angle (removing the need to inject at a proper angle as is the case with syringes), as well as by replacing a long, thin plunger of a syringe with a simple button which is depressed and held to inject the dose.

A study done in African countries, reports that 15% to 60% of clinics reuse immunisation needles and syringes without proper disinfecting, resulting in increasingly large cases of unsterilised injections. 55% of North-western China’s health care workers reported having used SUDs, resulting in an estimated 135 to 3120 per 100,000 population ...
In syringes, plungers are constrained to linear motion as they are pulled and pushed within an outer tube or "barrel." The plunger allows the syringe to take in or expel fluid through an orifice at the open end of the barrel. In disposable syringes, the plunger is often made of plastic with a rubber tip that seals between itself and the barrel.

Development of the fully disposable hypodermic needle was spurred on in the 1950s for several reasons.

The widespread immunization against polio during the period required the development of a fully disposable syringe system ...
