2. Birmingham gauge - Wikipedia

   en.wikipedia.org/wiki/Birmingham_gauge

   For larger mechanical tubing, however, the gauge number indicates the wall thickness, independent of the tube's overall size. In medicine, the Birmingham gauge is widely used to specify the outer diameter of hypodermic needles, catheters, cannulae, and suture wires. However, catheters are more commonly defined using the French catheter gauge ...

3. Hypodermic needle - Wikipedia

   en.wikipedia.org/wiki/Hypodermic_needle

   Hypodermic needles are normally made from a stainless-steel or Niobium tube [17] through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The end of the needle is bevelled to create a sharp pointed tip, letting the needle easily penetrate the skin. [18] A hypodermic needle tip under ...

4. Syringe - Wikipedia

   en.wikipedia.org/wiki/Syringe

   1865: Charles Hunter coined the term "hypodermic", and developed an improvement to the syringe that locked the needle into place so that it would not be ejected from the end of the syringe when the plunger was depressed, and published research indicating that injections of pain relief could be given anywhere in the body, not just in the area of ...

5. Intradermal injection - Wikipedia

   en.wikipedia.org/wiki/Intradermal_injection

   Most intradermic needles require a change in injection technique or instruction to use, for example a perpendicular intradermal injection. [4] Immune reaction tests sometimes use a set of non-hollow needles for scarification, shallowly abrading the skin. The inoculation is limited to the dermis.

6. Surgical suture - Wikipedia

   en.wikipedia.org/wiki/Surgical_suture

   The ski and canoe needle design allows curved needles to be straight enough to be used in laparoscopic surgery, where instruments are inserted into the abdominal cavity through narrow cannulas. Needles may also be classified by their point geometry; examples include: taper (needle body is round and tapers smoothly to a point)

7. Winged infusion set - Wikipedia

   en.wikipedia.org/wiki/Winged_infusion_set

   It consists, from front to rear, of a hypodermic needle, two bilateral flexible "wings", flexible small-bore transparent tubing (often 20–35 cm long), and lastly a connector (often female Luer). This connector attaches to another device: e.g. syringe , vacuum tube holder/hub, or extension tubing from an infusion pump or gravity-fed infusion ...
