Hohlnadeln

Hohlnadeln, commonly known as hollow needles, are specialized medical devices designed for precise injection or extraction of fluids. They typically consist of a slender, tubular structure with a sharp distal tip that facilitates easy penetration through tissues. The hollow nature of these needles allows for the transfer of liquids such as medications, blood, or other biological samples, making them essential tools in healthcare, laboratory, and veterinary settings.

Hohlnadeln are manufactured from medical-grade stainless steel or other biocompatible materials to ensure durability and minimize the risk of contamination or allergic reactions. They vary in gauge, length, and tip configuration to accommodate different procedures. For example, finer gauges are used for precision injections, while larger gauges are suitable for drawing or administering larger fluid volumes.

The design of hollow needles emphasizes sharpness and structural integrity to reduce patient discomfort and improve fluid flow efficiency. Safety features, such as protective caps and needle guards, are often incorporated to prevent accidental needle sticks and ensure proper disposal.

Common applications include administering vaccines or medications, withdrawing blood samples, and delivering anesthetics. Hygienic protocols, including sterilization and proper disposal, are critical to reduce infection risks associated with needle use.

Hollow needles have a long history in medicine, evolving to include innovations that enhance safety, usability, and patient comfort. Their design principles continue to influence the development of injectors and fluid transfer devices across healthcare sectors. Despite technological advancements, the fundamental concept of the hollow needle remains a vital component of modern minimally invasive procedures.
