Abstract: The present aids and their attendant methods allow injectors to achieve injection and sampling using syringes with reduced danger of incurring accidental needle punctures upon themselves. Injection aids feature a needle cap receptacle as part of the aid such that a needle may be uncapped, the cap being retained on the injection aid. In accordance with present methods, a fold of skin may be created with the aid in order to facilitate insertion of the needle. The used needle may thereafter be inserted into the protective cap while that cap is retained on the injection aid, rather than being held in the fingers of the injector. Kits are also provided comprising the injection aids of the invention.

Abstract: An apparatus comprises a housing having a shape and size suitable for being held in a single hand of a user. A nail file head is coupled to the housing. An electric drive device is contained within the housing and configured to rotationally oscillate the nail file head about an axis. An abrasive surface is coupled to the nail file head configured to trim or smooth a fingernail or toenail when the nail file head is oscillated. The abrasive surface extends around and faces radially away from the axis.
