Skin antiseptic applicator and methods of making and using the same

Abstract

The invention relates to applicators for applying a solution or other composition (e.g., an antiseptic composition) to skin of a patient. The applicator may include a container body having a proximal end, a distal end, and a frangible member disposed at the distal end of the body. The applicator includes a first position where the container body and frangible member are a unitary piece (e.g., blow molded as a single piece), and a second position when the frangible member is rotated relative to the body to irreversibly break a weak point therebetween, releasing the composition in the hollow body through an opening. A porous applicator head may be positioned adjacent the distal end of the body and frangible member, so that the composition flows out the body, through the opening, and onto the head. The applicator may be formed in a blow-fill-seal process for improved sterility and ease of manufacture.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 836,052, filed Jun. 17, 2013, and is a Continuation of U.S. application Ser. No. 14 / 261,360 filed on Apr. 24, 2014, the disclosure of both of these applications is incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. The Field of the Invention[0003]The present invention is directed to skin antiseptic composition applicators, particularly to skin antiseptic composition applicators that include one or more antimicrobial (e.g., antiseptic) materials in a single use applicator. Typically such skin antiseptic applicators are used in preparation for surgery to decolonize the skin prior to surgery and provide some protection to the patient's skin after surgery to prevent infection and aid in the healing process.[0004]2. Description of Related Art[0005]Antiseptic preparation of patient's skin for surgery conventionally includes a...

AI Technical Summary

Benefits of technology

The present invention is directed to an applicator for applying a composition, such as an antiseptic or personal care composition, to a patient's skin. The applicator includes a container body with a frangible member positioned at the distal end of the container body. The frangible member is designed to break away from the container body at a weak point therebetween to release the composition. The applicator has an applicator head formed of porous material positioned adjacent to the distal end of the container body. The composition flows out of the container body through the opening in the applicator head. The applicator is designed to be easy to use and apply the composition to the patient's skin.

Problems solved by technology

While inexpensive, these techniques are messy and offer little control over inadvertent dripping of the composition into areas where it is undesired.

Since many of the available compositions contain active ingredients such as alcohol, iodine or chlorhexidine gluconate, dripping or pooling of such compositions at unintended locations can be irritating when left in contact with the skin.

One of the challenges associated with using such skin antiseptic compositions is the need to sterilize the exterior of the applicator while minimizing potential byproducts that may be produced when the composition is exposed to sterilization compounds such as ethylene oxide gas.

Reactive sterilants such as ethylene oxide may react with the active antimicrobial agent or with other components in the skin antiseptic composition, altering the potency or producing potentially toxic compounds.

One recurring problem with such existing skin antiseptic applicators is that the solutions provided to minimize ethylene oxide penetration also add additional cost and complexity to the applicator devices.

One of the challenges associated with these skin antiseptic applicators is that the CHG or similar antiseptic compositions are often not stable with dye components.

One problem with such existing skin antiseptic applicators containing multiple compartments for housing the dye separate from the antiseptic composition is that a multi-chamber applicator increases costs and complexity in the manufacturing process.
