[edit] Aprilophobia?
Sounds like someone's idea of a joke stemming from April O'neill from the TNMT... Any references? Undead Herle King 20:40, 16 May 2007 (UTC)
[edit] sizing
I had a quick go at trying to find a nice sizing chart. But it's difficult because of the different standards.
here's this, it's pretty wrong i think, the site the data comes from wasn't a manufacturer or anything. In other places the numbers aren't that 'round'.
27G 0.40 mm 26G 0.45 mm 25G 0.50 mm 24G 0.55 mm 23G 0.60 mm 22G 0.70 mm 21G 0.80 mm 20G 0.90 mm 19G 1.10 mm 18G 1.20 mm
here are some other sites i'll bookmark with tables or lists of conversions.
- This has the colour codes people i kknow have used.
- These people sell needles, surely they'd know
- Spinal needles
- Specifications
- This has a colour chart, no mm diameters though
- French catheter chart
- Another one, but a pdf so you can use in
- Info on wire, and wire sizes. See wire.
- lots of custom needles

[edit] History?
As an editor on the hypnosis entry, it is important to understand when the hypodermic needle was invented and perhaps the implications. Would someone be willing to write something about the history? Thanks! DrMattGomes 03:59, 30 October 2005 (UTC)
In this http://www.cnn.com/2006/LAW/07/31/basement.lipo.ap/index.html cnn article it is revealed that you can actually be chraged with "illegal possession of a hypodermic needle". I wonder if there's an exeption for filling your ink cartridges, for example.
There is a need for historic background. Here is an article as an example: http://inventors.about.com/library/inventors/blsyringe.htm
I watched an episode of Modern Marvels on Opium and it alluded that the hyperdermic syringe was developed to deliver morphine to the blood system.
[edit] It is estimated that about 10% of the adult population may have a phobia of needles (Trypanophobia),
This statement is quite questionable. Trypanophobia is a fear of Injections, yet it states it as being a fear of needles. Needs to be changed I think. 82.21.53.146 16:39, 24 October 2007 (UTC)
[edit] Phobia section
The Phobia section (as seen on the time stamp at the end of this post) is very good. It is short, to the point (hehe), concise and reflects everything my mother has told me in her experience as a nurse in a state hospital. Good work guys! JayKeaton (talk) 15:15, 29 December 2007 (UTC)
[edit] Directly into the blood stream?
Does anyone know if all injections meant for the bloodstream go there directly, or if not, what happens "in between"? —Preceding unsigned comment added by 99.227.76.232 (talk) 06:04, 23 February 2008 (UTC)
