drug delivery device |
| abstract |
A drug delivery device provided with a stainless steel needle or cannula, wherein the patient end of the needle or cannula has a protective outer layer on the surface of the needle or cannula. The protective outer layer has a thickness and is configured to prevent or minimize contact of the patient's tissue with the stainless steel to prevent or inhibit an allergic reaction caused by tissue contact with the nickel in the stainless steel. The protective outer layer may be a metallic coating of a non-allergenic metal (eg, gold), or may be other coating material capable of covering the exposed surface of the needle to prevent direct contact of the stainless steel with the patient. |
