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 [[:wikt:orifice|orifice]] at the front (open) end of the tube. The open end of the syringe may be fitted with a [[hypodermic needle]], a [[nozzle]] or [[tubing (material)|tubing]] to direct the flow into and out of the barrel. Syringes are frequently used in [[clinical medicine]] to administer [[injection (medicine)|injections]], infuse [[intravenous therapy]] into the bloodstream, apply compounds such as [[glue]] or [[lubricant]], and draw/measure liquids. There are also '''prefilled syringes''' (disposable syringes marketed with liquid inside).

Injecting of [[air]] into a [[blood vessel]] is hazardous, as it may cause an [[air embolism]]; preventing embolisms by removing [[air]] from the syringe is one of the reasons for the familiar image of holding a hypodermic syringe pointing upward, tapping it, and expelling a small amount of liquid before an injection into the [[bloodstream]]. [19] => [20] => The [[barrel]] of a syringe is made of [[plastic]] or [[glass]], usually has graduated marks indicating the volume of [[fluid]] in the syringe, and is nearly always transparent. Glass syringes may be [[Sterilization (microbiology)|sterilized]] in an [[autoclave]]. Plastic syringes can be constructed as either two-part or three-part designs. A three-part syringe contains a plastic plunger/[[piston]] with a [[rubber]] tip to create a seal between the piston and the [[barrel]], where a two-part syringe is manufactured to create a perfect fit between the plastic plunger and the barrel to create the seal without the need for a separate synthetic rubber piston. Two-part syringes have been traditionally used in [[Europe|European countries]] to prevent introduction of additional materials such as silicone oil needed for lubricating three-part plungers.{{cite web |title=The Anatomy of the Hypodermic Needle and Syringe |url=https://www.exchangesupplies.org/article_the_anatomy_of_a_hypodermic_needle_and_syringe.php |website=www.exchangesupplies.org |access-date=18 May 2021}} Most modern medical syringes are plastic because they are cheap enough to dispose of after being used only once, reducing the risk of spreading [[blood-borne disease]]s. Reuse of needles and syringes has caused spread of diseases, especially [[HIV]] and [[hepatitis]], among intravenous drug users. Syringes are also commonly reused by diabetics, as they can go through several in a day with multiple daily insulin injections, which becomes an affordability issue for many. Even though the syringe and needle are only used by a single person, this practice is still unsafe as it can introduce bacteria from the skin into the bloodstream and cause serious and sometimes lethal infections.{{cite web|url=http://www.cnn.com/2011/HEALTH/expert.q.a/09/28/insulin.syringe.brawley/index.html|title=Is it safe to reuse an insulin syringe? - CNN.com|first=Asked by|last=Bethany|website=[[CNN]]|url-status=live|archive-url=https://web.archive.org/web/20170710123054/http://www.cnn.com/2011/HEALTH/expert.q.a/09/28/insulin.syringe.brawley/index.html|archive-date=2017-07-10}} In medical settings, single-use needles and syringes effectively reduce the risk of cross-contamination.{{cite web|title=Disposable Medical Supplies Markets|publisher=TriMark Publications, LLC|date=July 2014|url=http://www.trimarkpublications.com/products/Disposable-Medical-Supplies-Markets.html|url-status=live|archive-url=https://web.archive.org/web/20140224004233/http://www.trimarkpublications.com/products/Disposable-Medical-Supplies-Markets.html|archive-date=2014-02-24}} [21] => [22] => Medical syringes are sometimes used without a needle for orally administering liquid medicines to young children or animals, or milk to small young animals, because the dose can be measured accurately and it is easier to squirt the medicine into the subject's mouth instead of coaxing the subject to drink out of a measuring spoon. [23] => [24] => ===Tip designs=== [25] => Syringes come with a number of designs for the area in which the blade locks to the syringe body. Perhaps the most well known of these is the [[Luer lock]], which simply twists the two together. [26] => [27] => Bodies featuring a small, plain connection are known as slip tips and are useful for when the syringe is being connected to something not featuring a screw lock mechanism. [28] => [29] => Similar to this is the catheter tip, which is essentially a slip tip but longer and tapered, making it good for pushing into things where there the plastic taper can form a tight seal. These can also be used for rinsing out wounds or large abscesses in veterinary use. [30] => [31] => There is also an eccentric tip, where the nozzle at the end of the syringe is not in the centre of the syringe but at the side. This causes the blade attached to the syringe to lie almost in line with the walls of the syringe itself and they are used when the blade needs to get very close to parallel with the skin (when injecting into a surface vein or artery for example).

Another application is to use the needle tip to add liquids to very confined spaces, such as washing out some scientific apparatus. They are often used for measuring and transferring solvents and reagents where a high precision is not required. Alternatively, microliter syringes can be used to measure and dose chemicals very precisely by using a small diameter capillary as the syringe barrel. [139] => [140] => The [[polyethylene]] construction of these disposable syringes usually makes them rather chemically resistant. There is, however, a risk of the contents of the syringes leaching plasticizers from the syringe material. Non-disposable glass syringes may be preferred where this is a problem. Glass syringes may also be preferred where a very high degree of precision is important (i.e. [[Quantitative analysis (chemistry)|quantitative chemical analysis]]), because their [[tolerance (engineering)|engineering tolerances]] are lower and the plungers move more smoothly. In these applications, the transfer of [[pathogens]] is usually not an issue. [141] => [142] => Used with a long needle or [[cannula]], syringes are also useful for transferring fluids through rubber [[septum|septa]] when atmospheric [[oxygen]] or [[moisture]] are being excluded. Examples include the transfer of air-sensitive or [[pyrophoric]] reagents such as [[phenylmagnesium bromide]] and [[N-Butyllithium|''n''-butyllithium]] respectively. Glass syringes are also used to inject small samples for [[gas chromatography]] (1 μl) and [[mass spectrometry]] (10 μl). Syringe drivers may be used with the syringe as well. [143] => [144] => ===Cooking=== [145] => Some [[culinary]] uses of syringes are injecting liquids (such as [[gravy]]) into other foods, or for the manufacture of some [[candy|candies]]. [146] => [147] => Syringes may also be used when [[cooking]] meat to enhance flavor and texture by injecting juices inside the meat, and in [[baking]] to inject filling inside a [[pastry]]. It is common for these syringes to be made of stainless steel components, including the barrel. Such facilitates easy disassembly and cleaning. [148] => [149] => ===Others=== [150] => Syringes are used to refill [[ink cartridge]]s with [[ink]] in [[fountain pen]]s. [151] => [152] => Common workshop applications include injecting [[glue]] into tight spots to repair joints where disassembly is impractical or impossible; and injecting lubricants onto working surfaces without spilling. [153] => [154] => Sometimes a large hypodermic syringe is used without a needle for very small baby [[mammal]]s to [[breastfeeding|suckle]] from in artificial rearing. [155] => [156] => Historically, large pumps that use reciprocating motion to pump water were referred to as syringes. Pumps of this type were used as early [[firefighting]] equipment. [157] => [158] => There are fountain syringes where the liquid is in a bag or can and goes to the nozzle via a pipe. In earlier times, [[clyster]] syringes were used for that purpose. [159] => [160] => Loose [[snus]] is often applied using modified syringes. The nozzle is removed so the opening is the width of the chamber.

More about us

About

It is used to administer medications, withdraw fluids, or inject fluids into the body. The syringe is commonly used in healthcare settings for various purposes, such as vaccines, blood sampling, insulin administration, and drug delivery. The barrel of the syringe is marked with precise measurements to ensure accurate dosage. The plunger is pushed to create pressure, forcing the fluid through the needle into the body. Syringes are available in different sizes and types, including conventional syringes, insulin syringes, and safety syringes. They have played a significant role in modern medicine, enabling healthcare professionals to deliver treatments efficiently and effectively.
