Needle Work

Students Elizabeth Nee, Angela Heppner, Briar Duffy and Jeffrey Phillips
An accidental needle stick — one hazard of suturing a wound — poses as much a risk to medical personnel as it does to patients. Ninety-six percent of suture-needle injuries occur with contaminated needles, which increase the potential for transmission of such diseases as hepatitis C or HIV. Looking for a safer alternative, biomedical engineering students (left to right) Elizabeth Nee, Angela Heppner, Briar Duffy and Jeffrey Phillips developed JABE 200. Their design includes a fluid-filled balloon that, when depressed, causes the suture needle to protrude from a protective sheath. Releasing the balloon mechanism retracts the needle.
