Needles are crucial tools with diverse applications, impacting various fields from medicine to crafting. Their importance stems from their ability to precisely deliver substances or create pathways through materials.
Medical Applications:
- Drug Administration: Hypodermic needles are essential for administering medications intravenously, intramuscularly, or subcutaneously, enabling rapid delivery of substances that cannot be ingested or absorbed otherwise.

Reuse of needles is dangerous, increasing the risk of infection. Source: CDC - Safe Injection Practices
- Blood Collection & Testing: Needles are used to collect blood samples for diagnostic testing and blood transfusions. The precision of the needle ensures efficient and relatively painless sample collection. Safe handling and disposal are crucial to prevent infections. Source: FDA - Safely Using Sharps
- Vaccinations: Needles facilitate the effective and safe delivery of vaccines, protecting individuals from various diseases. Proper needle size and injection technique are critical for effective vaccination. Source: NCBI - The importance of injecting vaccines into muscle
- Acupuncture: In acupuncture, needles are strategically placed to stimulate specific points on the body, aiming to relieve pain and promote healing. Sterile needles are vital to prevent infection. Source: Johns Hopkins Medicine - Acupuncture
Non-Medical Applications:
- Sewing & Crafting: Needles are fundamental tools for sewing, embroidery, and other crafts, enabling the creation of textiles and various art forms. The needle's design allows it to create a passage for thread, forming loops that bind materials together. [Reference Material Provided]
