Painless injection technology

Painless injection technology can be performed with a device that creates pressure and vibration when the injection is inserted into the skin.

A new study presented at the annual meeting of the American Society of Anesthesiologists shows that it is easier to vaccinate newborns and adults in the future thanks to painless injection technology , Popsci. reported.

It is estimated that one in 10 people are afraid of needles, which can cause some negative consequences such as reducing the rate of vaccination and blood donation.

"Our initial study came up with the idea that using a device to create pressure and vibration before injection can significantly reduce pain by closing the" gate "that sends the pain signals sent to. brain, " Popsci quoted Professor William McKay, the lead author of the study from the University of Saskatchewan, Canada, said in a press release.

Gate theory of pain perception suggests that human pain occurs when stimulating pain passes through nerve control gates along the spine to the brain. By occupying these gates with other sensory signals such as vibration and pressure, the team removed the feeling of the needle by distracting the defense function of the nervous system.

The team also looked at the effect of temperature (hot and cold) on this process for 21 volunteers. They found that the combination of pressure and vibration seemed to have the most powerful analgesic effect, if increased temperature accompanied by a combination of pressure and vibration also reduced pain but not significantly.

Researchers hope that by quantifying the pain of participants can help develop a needle that does not hurt patients in the near future.
