The butterfly offers advantages over a simple straight needle. The butterfly's flexible tubing reaches more body surface and tolerates more patient movement. The butterfly's precise placement facilitates venipuncture of thin, "rolling", fragile, or otherwise poorly accessible veins.

[1] Bidens means two- toothed, describing the two projections found at the top of the seeds, and alba refers to the white ray florets. [ 2 ]
Changing needle size is the best way to control one's own gauge for a given pattern and yarn. Finally, the knitter's tension, or how tightly one knits, can affect the gauge significantly. The gauge can even vary within a single garment , typically with beginning knitters; as knitters become more familiar with a stitch pattern, they become more ...

A sewing needle, used for hand-sewing, is a long slender tool with a pointed tip at one end and a hole (or eye) to hold the sewing thread.The earliest needles were made of bone or wood; modern needles are manufactured from high carbon steel wire and are nickel- or 18K gold-plated for corrosion resistance.
Changing yarn weight or needle size can have a significant impact on the finished project, so standardized systems have been spread about, as well as conversion systems for regional standards (especially needle sizes). [1] Yarn weight is important in achieving the correct gauge or tension for a particular project and can help with yarn ...
Needle has distinct "wings" on either side of the eye which hold the fabric open. Often used on hems and borders, and for decorative finishing. A larger size needle will leave a larger hole in the final piece of sewn fabric. Leather: These have a distinct triangular point to help the needle make a large, clean hole in non-woven materials like ...
The needle was introduced as a safer technique to give patients such pneumothoraces. It was not until 1938, when he published his invention in the German literature, that the needle became more broadly known outside of Hungary. [4] Raoul Palmer introduced the use of the Veress needle in laparoscopy to establish a pneumoperitoneum. [5]
Card reader fully automated schiffli embroidery machine by Saurer. Needle spacing, or pitch, limited the width of the embroidered design. The spacing between the needles is known as rapport. The unit for measuring spacing was the French inch (1.08 English inch). Standard spacing was known as 4/4 rapport. Machines with 3/4, 4/4, and 6/4 were ...
