There ’s nothing bad than pulling off a bandaid , especially when it yanks nearby hair out with it . Thankfully , researchers have evolve a newfangled kind of medical tape that stay attached to your skin , but can be removed without any pain or damage .
Biomedical Engineers from Harvard and MIT have been working with the trouble of medical taping . Not only does it hurt , but its adhesive powers can actually damage cutis and cause scars in sister and the elderly . So , how do you create a tape that does n’t hurt to pull off?You intention it to separate somewhere else .
Traditionally , tapes have an adhesive layer that gravel directly to the skin . That learn a lot of force play to pull off . The problem is that some citizenry ’s skin is weaker than the glue , and that go to the expected problem . This new aesculapian tape is really represent of three bed rather than the traditional two . There ’s an extra layer between the patronage and the adhesive material . The material are designed to be very inviolable against shear military unit , but peel off easily when pulled back 90 degree . That way they can still hold medical equipment in place , but be easily removed .
So , what happens when you pull off the tape ? The tape designedly erupt between the adhesive and the backing rather than between the adhesive and the skin . This lead a flimsy layer of adhesive intact on the skin – and this can then be gently scraped off without damaging even super frail patients .
“ Current adhesive magnetic tape that contain financial backing and adhesive layers are tailored to break at the adhesive - skin interface . With adults the adhesive fail leaving little remnant of adhesive on the skin while with slight neonate peel , the fracture is more likely to occur in the peel have significant damage , ” order one of the sketch ’s authors , Dr. Jeffrey Karp , in a release . “ Our approach transitions the geological fault zone away from the cutis to the adhesive - back interface thus completely preventing any hurt during remotion . ”
The authors arrogate that some 1.5 million wound are commemorate each year from mag tape removal – but with this novel tape , bandaid injuries could be history .
