ABSTRACT:
This invention relates to augmented polymeric hypodermic needles and lancets. A flexible polymeric hypodermic needle or lancet is stiffened and made to more readily pierce the skin by working in conjunction with an augmenting structure. The devices are by their nature safer than present metal hypodermic needles or lancets. "Anti-stick", one-time use, and safety shielded models are demonstrated. Novel manufacturing methods will lead to devices that are less expensive than their metal counterparts. Unlike metal hypodermic devices these can be easily incinerated. This invention makes possible safe, easy to use, low cost, disposable hypodermic devices for injection, blood sampling and testing.
