Introduction
Injection syringes with needles are essential medical instruments used in various healthcare applications, from vaccinations to medication administration. Understanding the specific components that constitute a syringe is crucial for healthcare professionals and manufacturers alike to ensure safety, efficiency, and effectiveness in medical procedures. This article presents a comprehensive breakdown of the parts of an injection syringe with a needle and provides insights into solutions offered by Longde Company.
Components of an Injection Syringe with Needle
-
Barrel
The barrel is the cylindrical component that holds the liquid medication. It is typically made from medical-grade plastic or glass and includes markings for dosage precision. The standard capacity of a syringe barrel can range from 0.5 mL to 60 mL, depending on its intended use.
-
Plunger
The plunger is a piston-like component inserted into the barrel's open end. Users can push the plunger to inject medication or pull it back to draw liquid into the barrel. Plungers are usually crafted from polypropylene for compatibility and smooth operation.
-
Plunger Seal
The plunger seal is a small rubber tip that ensures a leak-proof seal between the plunger and the barrel. It prevents medication leakage and maintains precision in liquid dosage.
-
Needle Hub
The needle hub is the connector between the syringe barrel and the needle. Often made from plastic, it ensures a secure attachment to prevent detachment during injection. Hubs are standardized to fit various needle sizes.
-
Needle
The needle is the metal component that penetrates the skin, allowing the medication to be delivered into the body. Needles vary in length (12mm to 38mm) and gauge (18 to 25G), tailored to specific medical needs and patient characteristics.
-
Needle Cap
A protective covering designed to keep the needle sterile and safe from contamination or accidental injury. The cap is typically removed right before use.
