  "abstract": "A cuff attachment for an isolator sleeve cuff, the cuff attachment comprising an annular band of substantially elastomeric material having an open first end and an open second end, the first end having a diameter which is wider than a diameter of the second end, the first end being adapted to be attachable to an isolator sleeve cuff, and the second end being adapted to releasably retain a plug therein. A plug for sealing the second end of the cuff attachment, the plug comprising a body sized and shaped to be releasably retained in the second end of the cuff attachment. An isolator sleeve system comprising the cuff attachment and the plug.",
  "claims": [
    "1. A cuff attachment for an isolator sleeve cuff, the cuff attachment comprising an annular band of substantially elastomeric material having an open first end, an open second end, and a plug for sealing the second end, the first end having a diameter which is wider than a diameter of the second end, the first end being adapted to be attachable to an isolator sleeve cuff, and the second end being adapted to releasably retain the plug therein, the diameter of the second end being less than a diameter of the plug when the second end is in a non-stretched state, and the second end being adapted to stretch to allow the plug to pass therethrough, and to substantially recover to form a seal around the plug when the plug is retained in the second end, in use; and the plug comprising a body sized and shaped to be releasably retained in the second end of the cuff attachment, and to be able to pass through the second end when the second end is stretched.",
    "2. The cuff attachment of claim 1, wherein the second end is arranged to form a seal around a wrist of the user's hand, when the hand is passed through the second end from the first end.",
    "3. The cuff attachment of claim 2, wherein the diameter of the second end is less than a diameter of the wrist of the user's hand, when the second end is in the non-stretched state.",
    "4. The cuff attachment of claim 1, wherein the first end is configured to be detachably attachable to the isolator sleeve cuff.",
    "5. The cuff attachment of claim 1, wherein the first end is arranged to form a seal around the isolator sleeve cuff, in use.",
    "6. The cuff attachment of claim 1, wherein the first end comprises a reinforced rim portion.",
    "7. The cuff attachment of claim 6, wherein the reinforced rim portion comprises a thicker annular portion of the substantially elastomeric material.",
    "8. The cuff attachment of claim 6, wherein the reinforced rim portion is sized and shaped to be engaged in an annular groove of the isolator sleeve cuff.",
    "9. The cuff attachment of claim 1, wherein the diameter of the first end is less than a diameter of the isolator sleeve cuff, when the first end is in the non-stretched state.",
    "10. The cuff attachment of claim 1, wherein the cuff attachment is a truncated cone shape.",
    "11. The cuff attachment of claim 1, wherein the plug comprises a handle extending from a back face of the body.",
    "12. The cuff attachment of claim 1, wherein the plug has an annular groove around the body for receiving the second end of the cuff attachment.",
    "13. The cuff attachment of claim 1, wherein the plug has a front face which is substantially convex.",
    "14. The cuff attachment of claim 1, wherein the body of the plug has a larger diameter at a back end than a front end.",
    "15. The cuff attachment of claim 1, further comprising an isolator sleeve having the isolator sleeve cuff, the isolator sleeve cuff having a first end arranged to releasably attach to a sleeve, and a second end arranged to releasably attach to the cuff attachment.",
    "16. The cuff attachment of claim 1, wherein the isolator sleeve cuff has an annular groove arranged to retain the first end or a reinforced rim portion of the first end of the cuff attachment in use.",
    "17. The cuff attachment of claim 1, wherein the open second end is arranged to allow the plug to pass therethrough in a direction of the first end to the second end, and in a direction of the second end to the first end."

  "description_excerpt": "The present disclosure relates to isolator sleeve systems, and more specifically although not exclusively, to isolator sleeve systems relating to a cuff portion of an isolator sleeve.\n\nIsolators typically comprise enclosures for isolating an inside workspace from an outside environment, thus providing a barrier for contaminants entering the inside workspace and/or for contaminants leaving the workspace and causing potential harm. Examples of isolators include, but are not limited to, restricted access barrier systems (RABS), closed RABS, compounding aseptic isolators, compounding aseptic containment isolators, and gloveboxes. Isolators are useful in the pharmaceutical, medical, chemical, and electrical engineering industries, such as in the manufacture or compounding of drugs in hospitals or pharmacies, handling radioactive and other dangerous materials, and manufacturing electronic components, to name a few.\n\nIn a typical isolator system, openings such as arm ports are provided on a front face of the isolator for allowing the hands and arms of a user to access the inside workspace. Sleeves are provided which are attachable to the arm ports and which extend into the workspace. Gloves are sealingly attachable to a distal end of the sleeve typically using a sleeve cuff such as a rigid ring with annular grooves. In use, a user puts his or her arms through the arm ports and into the sleeves wearing a pair of inner disposable gloves.",
