30 Gauge Needle
A 30 gauge needle is a type of needle commonly used in medical procedures, infusions, and vaccinations. The gauge number, which is typically listed on the packaging of the needle, indicates the thickness of the needle. A higher gauge number means the needle is thinner, which allows for faster fluid flow and reduced risk of air embolism when drawing up solutions. Conversely, a lower gauge number indicates a thicker needle, which is更适合 for deeper injections or when you need greater control over the injection site.
Characteristics of a 30 Gauge Needle
- Diameter: A 30 gauge needle typically has an outer diameter (O.D.) of 0.47 to 0.48 millimeters (mm).
- Length: The length of a standard 30 gauge needle is typically around 16 to 18 inches (406 to 457 millimeters) long, but may vary depending on the specific manufacturer and the intended use.
- Material: Most 30 gauge needles are made of surgical steel, with some models also incorporating polypropylene hubs for added flexibility.
- Hub Style: Some 30 gauge needles feature a small hub that allows them to be Removable, meaning they can be detached from the syringe and replaced with a different type of needle.
- Wall Thickness: The wall thickness of a 30 gauge needle is generally thin, with a thickness between 0.10 to 0.13 mm.
- Bevel: A 30 gauge needle typically has a straight bevel, meaning the tip is rounded and smooth, which reduces the risk of injury to the patient.
Applications of a 30 gauge Needle
- Injections: Often used for intramuscular or subcutaneous injections, especially where precision is crucial.
- Infusions: Used for administering medications intravenously in a hospital setting, such as when using a central line.
- Vaccinations: Commonly used for routine vaccinations, due to their versatility and low cost.
- Liquids Administration: Such as when Drawing up medications from a dropper or a vial.
- Other Medical Procedures: May be utilized in various other medical procedures where small gauge needles are preferred.
