Augmented polymeric hypodermic devices
First Claim
1. A hypodermic device for performing a piercing process comprising:
- a flexible polymeric piercing member with at least one lumen and a piercing tip;
and an augmenting means at least partly about and slidably engaged with said piercing member and includesa resilient foam at least partly about said piercing member anda guard at least partly about said foamwherein said augmenting means provides such stiffness to said piercing member in order for said piercing member to perform the piercing process.

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.
