Abstract: A holder for securing and protecting an intravenous injection needle when the needle is inserted in the body of a patient is disclosed. The holder includes a flat base having an adhesive bottom with an aperture located in the middle of the base. A clear plastic window, having an adhesive bottom, is placed over the aperture on the base. When the needle is inserted in the body, the base is placed over the needle so that the insertion site lies in the middle of the aperture. The base securely holds the needle in place, and the clear window covers and protects the needle while allowing the needle insertion site to be observed. The window can be partially peeled back to provide access to the needle, and if desired the window may be completely peeled off and replaced. A see through gauze pad to which an antibiotic salve can be applied is also disclosed. This gauze pad is removably placed underneath the clear window in the aperture.
