Unit dose breakable vial with integrated brush applicator

摘要

A disposable sterile breakable vial includes a handle section and a vial section which are completely separable in response to a manually applied separation force. The vial section includes a sterile void dimensioned to contain a unit dose of a sterile therapeutic topical agent. An elongated member comprises a proximal portion supported by the handle section and a distal portion provided with a sterile applicator element, such as a brush. At least the applicator element is completely enclosed within the vial section with the applicator element immersed within the therapeutic topical agent. A hermetic seal between the handle and vial sections maintains sterility of at least the vial section prior to handle and vial section separation. Complete separation of the handle section and the vial section exposes the elongated member and the applicator element for topical application of the therapeutic agent saturating the applicator element.
