This device delivers a tiny, high-pressure jet of medicine through the skin without the use of a hypodermic needle. The device can be programmed to deliver a range of doses to various depths.
“If you are afraid of needles and have to frequently self-inject, compliance can be an issue,” says Catherine Hogan, a research scientist in MIT’s Department of Mechanical Engineering and a member of the research team. “We think this kind of technology … gets around some of the phobias that people may have about needles."
Through testing, the group found that various skin types may require different waveforms to deliver adequate volumes of drugs to the desired depth.
“If I’m breaching a baby’s skin to deliver vaccine, I won’t need as much pressure as I would need to breach my skin,” Hogan says. “We can tailor the pressure profile to be able to do that, and that’s the beauty of this device.”
- Less Pain.
- Controlled exact dose injected.
- Controlled Depth.
- Another advantage of this method of drug delivery over the old hypodermic syringe is that it can reduce the potential risk of accidental needle-stick injuries. The Centers for Disease Control and Prevention estimates that about 385,000 accidental needle-stick incidents occur each year among hospital-based health care workers in the U.S.
