Slip-Resistant Autoinjectors
In an embodiment, the present invention provides an autoinjector that has one or more slip-resistant features. In certain embodiments, the exterior surface of the autoinjector housing forms at least one of indentures and protrusions that impart a slip-resistant texture to the housing of the autoinjector. In other embodiments, the one or more slip-resistant features are included on a label, which comprises a label substrate and is attached to the exterior surface of the housing of the autoinjector. The features are designed to improve the handling properties of the autoinjector and reduce the likelihood that the autoinjector will slip out of a user's or caregiver's hand during use.
