A joint research team at KAIST developed an intravenous (IV) needle that softens upon insertion, minimizing risk of damage to blood vessels and tissues. Once used, it remains soft even at room ...

However, medical IV needles, made of hard materials such as stainless steel or plastic that do not mechanically match the soft biological tissues of the body, can cause critical problems in health ...

However, medical IV needles, made of hard materials such as stainless steel or plastic which do not mechanically match the soft biological tissues of the body, can cause critical problems in ...

The new IV needle, which is rigid at room temperature like a conventional one, softens when it is inserted and reaches body temperature. Bioengineers in South Korea have succeeded in developing an ...

Bioengineers in South Korea have succeeded in developing an intravenous needle (IV) that can bend and flex as it enters the human body. The softening IV needle is rigid at room temperature, similar to ...

While intravenous needles need to be rigid in order to pierce the skin, that rigidity sometimes causes damage to the veins. A new needle addresses that issue by softening upon insertion into the ...
