“Substantially painless” needleless injection developed in the Netherlands

Amsterdam, October 13-Under development by Dutch researchers Laser technology that enables “substantially painless” injections Without the needles they say, they will relieve fear and lower vaccination thresholds.

The “bubble gun” uses a laser to push small droplets into the outer layers of the skin, says David Fernandez Rivas, a professor at the University of Twente, the research affiliate of the Massachusetts Institute of Technology, who founded the idea.

“It shouldn’t cause pain,” he said, as the process is faster than a mosquito bite and does not touch nerve endings in the skin, adding that this will be studied further.

“Within a millisecond, the glass containing the liquid is heated by the laser, creating bubbles in the liquid that pushes the liquid out at speeds of over 100 km / h (60 mph),” he said in an interview. .. In his lab.

“It allows us to penetrate the skin without damage. No scratches or entrances are found.”

Rivas hopes that the present invention will not only help more people to be vaccinated, but also prevent the risk of contamination by dirty needles and reduce medical waste.

Testing of tissue samples was successfully conducted with a € 1.5 million ($ 1.73 million) European Union grant. According to Rivas, an application to fund the start of volunteer human testing will be submitted this month.

He said a new start-up will work with the pharmaceutical industry to test and sell “bubble gun” technology.

General phobia

However, depending on research progress and regulatory issues, it can take a year or three for this method to become generally available.

Approximately one in five Dutch people are afraid of needles, said Genk Schenck, who offers treatments to help those in severe suffering. “Needle phobia is more common than you think. People are ashamed to admit it.”

Some people are afraid to trace their fears back to traumatic childhood hospitalizations or give up control. A minority of about 1 in 1,000 suffers from deep phobia and requires repeated sessions to prepare for the jab.

“During the (coronavirus) pandemic … you’ll see a lot of people who could get around it now facing the wall. People who need to get the COVID-19 vaccine this year are for me It’s an important group. “

Patient Astrid Nysen, a 31-year-old musical actress who had 10 sessions with Schenck, says she is worried about getting vaccinated without a needle.

“It started in adolescence. When I see a needle or have to shoot, I just want to leave. I break the place just to prevent it from being shot,” she said.
