Needle - less engineering for shoot medicine is nothing unexampled . But , until now , it ’s relied on compressed air or gasolene cartridges to infract the tegument and deliver the dosage .
A team ofmedical and mechanically skillful engineering researcher from MIThas developed a fresh technology for needle - less injectant that trust on not compressed molecules but magnetic muscularity .
The equipment expend something called a “ Lorentz - force actuator ” ( a small , herculean attractor wall by a coil of wire that ’s sequester to a Walter Piston inside the drug phial ) that , power by an electric current , creates an adjustable gamey - pressure jet-propelled plane and ejects it out of a microscopically narrow nozzle . This acerate leaf - thin flow of air penetrates the peel to turn in highly controlled acid at dissimilar depths .
At nigh the hurrying of phone , the twist is able of come in a drug in high air pressure acid of up to 100 megapascals , in under a msec . It is so sensible , mid - way through the injection the velocity of the injection can be adjusted by alter the electrical current — higher velocity to break the peel ’s surface , slightly lower to mete the drug into the blood stream and surrounding tissue paper .
The benefits of this “ needle - less needle ” are on the face of it interminable : Of course , those with an aversion to needle will be soothe by the alternative injection , especially the great unwashed like diabetics , who routinely must administer ego - injections . But also the fortune of needle - stick harm will be mitigate , as will the risk of contract a disease off a polluted needle .
Ian Hunter , the Professor of Mechanical Engineering who led the research squad , explains that because the equipment can also take a drug in powdered variety — it tickle at such a pace that the drug do as though it were a liquid being shoot through the skin — parcel out injections in developing countries will be easier , as powder involve no infrigidation or cooling .
Not yet available , though hopefully soon , further development ofthe jet-propelled plane - injection deviceis currently underway . [ GizMag – Image viaTatiana Popova / Shutterstock ]
