Abstract: 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. After identifying or selecting the injection or incision site, the device is placed on the site for a time sufficient to achieve localized disinfection, and optionally localized anesthesia. Then the needle or surgical instrument is inserted through the composition into the site. Thereafter, the drug is administered, fluid is removed, in the case of an injection, or the surgical instrument is placed at the site, in the case of an incision.

Abstract: Disclosed is a device 10 for a video screen 16 which includes a support member 12 member disposed about the circumference of the video screen 16. The support member 12 has walls with interior reflective surfaces 30. A plurality of point light sources or lamps 32 are mounted to the support member 12 and positioned to provide to inner and outer concentric frames 50 and 52 of light on the screen 16. The inner frame 52 comprises a series of discrete point light images or dots 46 near the circumference of the screen 16 formed by light from the light sources being cast directly onto the screen. The outer frame 50 comprises a series of discrete point light images or dots near the circumference of the screen 16 formed by light from the light sources 32 first reflecting off the reflective surfaces 30 and then onto the screen 16. The intensity of the light from the inner frame 52 is less than the intensity of light from the outer frame 50.
