stripes on hypodermic needles

stripes on hypodermic needles could be used to accurately approximate depth, which I read makes a difference.

I haven't seen a needle with a ruling on it, yet I have read a study saying they researched the difference between a 1/4 inch and a 1/2 inch penetration depth and could now refer the new 1/4 inch for approval.

It seems like practitioners, and particularly developing world medical people could benefit from putting depth lines on hypodermic needles.

Who knows, perhaps it moves the efficacy 5% That is big when you consider an entire country.

       What is this "inch" you refer to ?   

       // when you consider an entire country. //   

       Giving an entire country an injection sounds like a challenge, although it is possible to give an entire country an enema once the national anus has been located. In the case of france, this is comparatively easy.

       This is not, in fact, an entirely stupid idea. It also eschews the use of "at". Hence [+].

       What would you propose as the material of choice for the marks?   

       8th, doesn’t it occur to you that with 1/4” markings, there would be fewer gradations than with 1 mm markings, causing the injectee to panic less as it plunges ever deeper?   

       Oh, what am I saying, of course you have. Must remember with whom I am talking.

       Doesn't sound dispractical. Could be a confeasible nonunilantiintelligent idea.

       Depth markings on other types of needles such as biopsy needles appears to be known (from a quick Google search).   

       I couldn't find anything for normal hypodermic needles. However, I think what might be more practical would be a depth stop rather than depth markings.

       <looks at the steel ruler I bought last year, one side metric, other side inches> Yep. there are still people who are on feet and inches.   

       [+] for two explicable and good ideas

       //what might be more practical would be a depth stop// Actually, that's a good point. If a needle is meant to penetrate to a depth of 8mm, why not use an 8mm long needle?

       (+) Depth stop after puncturing skin or bone is a huge problem.   

       Cool TED talk by the guy who figured out the solution. [link]   

       It was hard to find. You'd think it would be at least one of the hits for the word 'needle'.   

       simple[+] The downside is that the most painless jab is a fast one, and it takes experience to learn that. A doctor trained to slowly push in to the right mark will be giving painful shots his whole career.

       //what might be more practical would be a depth stop//   

       What about a needle whose length is adjustable? Just dial or otherwise adjust it to the appropriate measurement and jab away without having to think about it.

       //jab away without having to think about it //   

       But that's what medics do anyway ...

       Everyone is different. There still has to be some individual patient referencing to know what the marks mean.
