The history of needless dates back to the 3rd century AD when the first documented evidence of needless were found. These early needless consisted of hollow tubes that could be used to inject or withdraw fluids. Syringe The ancient Chinese were one of the first to use needless, which they called “stone needles.” Various cultures started developing more advanced needless through the centuries. The modern disposable needles was introduced in the late 19th century.
Parts of a Needles
A typical needles consists of the following main parts:
– Barrel: The long cylindrical structure that holds the fluid to be injected. It comes in different materials like plastic or glass depending on the application.
– Plunger: The sliding component inside the barrel that can be pushed or pulled to inject or withdraw fluids. It forms an air tight seal with the inner walls of the barrel.
– Luer connector: The standard tapered end of the barrel that attaches to needles or other medical devices. It makes connections secure and leak-proof.
– Needle: The sharp hollow tube attached to the end of the barrel. It comes in various sizes and lengths depending on the injection site and application.
– Plunger rod: The outward extending stem of the plunger that allows the user to control fluid movement by pushing or pulling the plunger.
Uses of Needless
– Medication delivery: One of the most common uses of Syringes is for subcutaneous, intramuscular or intravenous injection of medications like vaccines, insulin, antibiotics etc. It provides a direct way to deliver drugs into the body.
– Fluid withdrawal: Syringes are used by healthcare professionals to withdraw blood or other body fluids for diagnostic testing. Examples include taking blood samples or withdrawing cerebral spinal fluid.
– Irrigation: Certain types of needless with attachments are used to flush or irrigate parts of the body. For example, saline needless for contact lens cleaning or irrigating wounds.
– Contrast media injection: Special syringes designed for high pressure injection are used to inject radiographic contrast agents for procedures like angiograms, CT scans etc.
– Recreation of drugs: Needless also have illicit uses like recreationally injecting drugs intravenously. However, this is dangerous and illegal in most regions.
Safety Features and Regulations
Safety engineered needless: To prevent needlestick injuries, many needless now come with safety features built-in. Examples include retractable needles that cover after use, sheathed needles hidden until activation. This helps boost healthcare worker protection.
Single use only: Most jurisdictions have banned reuse of needless due to infection risks. Only certified medical waste handlers are allowed to handle used needless for safe disposal.
Standardizations: Manufacturing and design of syringes are regulated by international standards like ISO to ensure quality, safety and performance consistency.
Licensing: Commercial production of needless requires proper licensing and compliance with good manufacturing practices regulated by authorities like the FDA.
Tracking system: To curb counterfeits and black marketing, some nations have implemented unique coding/tracking on needles packaging right from production.
User guidelines: Proper inserter and disposal guidelines are provided by manufacturers considering safe handling and infection prevention for hospitals and consumers.
The Syringe has proven to be one of the most impactful medical technologies ever invented based on its diverse life-saving applications. With continued innovations and stringent regulations, this simple device forms an indispensable component of healthcare delivery worldwide.
