A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the ...
Safety needles [1] serve the same functions as safety syringes, but the protective mechanism is a part of the needle rather than the syringe. Legislation requiring safety syringes or equivalents has been introduced in many nations since needlestick injuries and re-use prevention became the focus of governments and safety bodies.
Individualized risk of blood-borne infection from a used biomedical sharp is further dependent upon additional factors. Injuries with a hollow-bore needle, deep penetration, visible blood on the needle, a needle located in a deep artery or vein, or a biomedical device contaminated with blood from a terminally ill patient increase the risk for ...
A hypodermic syringe has the ability to retain liquid and blood in it up to years after the last use and a great deal of caution should be taken to use a new syringe every time. The hypodermic needle also serves an important role in research environments where sterile conditions are required.
This article needs to be updated.The reason given is: the section related to E.U. needs further updates (esp. in sections 3.2 and 4.2.2) as the directives 93/42/EEC on medical devices and 90/385/EEC on active implantable medical devices have been fully repealed on 26 May 2021 by Regulation (EU) no. 2017/745 (MDR); furthermore, Brexit triggers updates in these sections (U.K. developed their own ...
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.

Multiple factors affect the depth and duration of local anaesthetics' action. Examples of these factors include the patients individual response to the drug, vascularity and pH of tissues at the site of drug administration, the type of injection administered etc. [ 3 ] Hence figures citing the duration of action of local anaesthetics is an ...
A wall-mounted sharps container. A needle remover is a device used to physically remove a needle from a syringe.In developing countries, there is still a need for improvements in needle safety in hospital settings as most of the needle removal processes are done manually and under severe risk of hazard from needles puncturing skin risking infection.
