Breaking The Skin Without The Sting
That in itself is not unique. Those have been already been around for a while. The problem is however that an IV needle will slip out if not being kept in place by tape. Staples could as well, but since no tape is used for those, that could result in leakage and other problems.
Those obstacles may be overcome in the near future with a new type of hypodermic needle and staple. The inspiration for them comes from, and you will never guess this; porcupine quills.
Studies have found that porcupine quills have small, backward-faced barbs. The quills slide in the skin easily, but stay in place due to those tiny 'anchors'. Several plastic models have already been developed and are currently being tested in the medical field.
The new needles and staples are modified to where they break the skin much easier, don't need to go in deep, stay in place, and are still removable without catching on to and damaging the surrounding tissue. This new discovery could also be used for the regular injection needle. That sure would take the sting out of it.
There are so many people around us who are in need. It is always better to give than to receive. That may hurt because it goes against our human nature, but knowing that giving away earthly treasures is laying up treasures in heaven, ought to be extremely comforting and be the greatest reward. That sure takes the sting out of it!
It is easier for a camel to go through the eye of a needle than for a rich man to enter the kingdom of God."
