A syringe is a simple yet essential medical device with several key components working together. Let's explore its parts:
Main Components of a Syringe
The core parts of a syringe include:
- Barrel: This is the cylindrical body of the syringe. It's graduated (marked with measurements) to accurately measure the liquid inside. The barrel holds the medication or fluid before injection or administration. As noted by Air-Tite Products Co., the barrel houses the plunger.
- Plunger: This is the cylindrical component that fits snugly inside the barrel. Pushing the plunger forces the liquid out of the syringe. It creates a seal within the barrel to ensure no fluid leaks.
- Needle (or Tip): The needle is a thin, hollow, pointed tube typically made of metal (stainless steel), Teflon, or plastic Chemyx.com. It pierces the skin or a container's seal to administer the fluid. Some syringes may use different dispensing methods, rather than a needle.
Additional Components
Depending on the type of syringe, these extra components might be present:
- Hub: This connects the needle to the barrel of the syringe Chemyx.com.
- Flange: Located at the end of the barrel, the flange provides a finger grip for better control while using the syringe SyringePumpPro.com. It helps prevent accidental slippage.
- Needle Adaptor: Found on some syringes, this allows for different needle sizes to be attached.
- Needle Bevel: The slanted tip of the needle, which facilitates smoother insertion. Wikipedia mentions this part specifically.
Types of Syringes
There are different types of syringes, and some may have additional or modified parts. For example, a three-part syringe, mentioned in KMed Health, simply refers to the three main components: barrel, plunger, and needle.
