Sharps – like needles, syringes, lancets and other devices used at home to treat diabetes, arthritis, cancer, and other diseases – should be immediately disposed of after use. Sharps waste is a form of biomedical waste composed of used "sharps", which includes any device or object used to puncture or lacerate the skin.
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.

Most autoinjectors are one-use, disposable, spring-loaded syringes (prefilled syringes). By design, autoinjectors are easy to use and are intended for self-administration by patients, administration by untrained personnel, or easy use by healthcare professionals; they can also overcome the hesitation associated with self-administration using a ...
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.
Development of the fully disposable hypodermic needle was spurred on in the 1950s for several reasons. The Korean War created blood shortages and in response disposable, sterile syringes were developed for collecting blood. The widespread immunization against polio during the period required the development of a fully disposable syringe system ...
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. An internal mechanism cracks the syringe when the plunger is fully depressed to prevent ...
Researchers developed a new jet injection design by combining the drug reservoir, plunger and nozzle into a single-use disposable cartridge. The cartridge is placed onto the tip of the jet injector and, when activated, a rod pushes the plunger forward. This device is known as a disposable-cartridge jet injector (DCJI). [2]
After this, Jalón worked on other designs, notably improvements on the disposable syringe, which was also a success. [13] His model had a plunger less prone to stick, made of plastic instead of glass, and with thin walls making disposal easier. [ 14 ]
