MIT Researchers Build “Needless” Injection Delivery System
Researchers at MIT have unviled a new high-pressure jet system for delivering medicines, a piece of hardware that is being called a “needless needle.”
The new system is now only capable of delivering medicines but also delivering them to different depths beneath the skin as set by the operator.
According to a member of the injection systems team in an interview with the Daily Mail:
“We think this kind of technology … gets around some of the phobias that people may have about needles.”
Known as the “jet injection” system the new medical device works through a Lorentz-force actuator which is a powerful magnet attached to a piston inside a drug-filled vial. As a current is applied to the device the magnet ejects the capsule at a high pressure which punctures the skin with the pain of a mosquito bit.
While other “needless needles” have been invented in the past this is the first one that can be adjusted for different depths and pressures. For example a doctor could use a low setting for a baby immunization injection and then use the high setting for an adult injection.
We probably won’t see this type of system in our doctors offices anytime soon but its none-the-less a cool glimpse into the future of medical devices that offer better results with less pain.
