  • Augmented polymeric hypodermic devices
    Patent number: 5607401
    Abstract: This invention relates to augmented polymeric hypodermic needles and lancets. The needles and lancets are stiffened by augmenting means so that they are able to pierce the skin. The devices cost less to manufacture and are safer to use than present metal hypodermic devices. They make possible new types of ampules, phlebotomy devices and intravenous catheters. Most of the models are completely burnable. This invention makes possible safe, easy to use, low cost, disposable hypodermic devices for injection, blood withdrawal and testing.
    Type: Grant

  • Augmented polymeric hypodermic devices
    Patent number: 5569213
    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.
