Devices, kits and methods for reducing the risk of infection at an injection or incision site are described herein. The device contains a bioadhesive, biocompatible and bioerodable material and one or more disinfectant agents. In the preferred embodiment, the material is formed of one ore more hydrogels. Optionally, the device also contains one or more anesthetics to decrease discomfort. The device may be marked or calibrated to facilitate localized injection or incision at a pre-specified site on the skin or mucus membrane. The disinfectant and/or anesthetic is delivered before, during, and/or after the treatment. Optionally, the disinfectant and/or anesthetic is released in a controlled-release manner. Optionally, the disinfectant and/or anesthetic may de delivered following a time-delay. In a second embodiment, the device may be placed at a site following the injection or incision at the site to reduce the risk of infection, provide anesthesia, and/or prevent reflux of blood or fluid following the injection or incision. |
