Sealing enclosure for finger tips

A fingertip enclosure apparatus for fitting over and sealingly enclosing a user finger tip and its fingernail, the apparatus comprising:

• an enclosure shell having a tubular shell side wall with a side wall proximal end and a side wall distal end, said side wall proximal end including a sealing structure protruding radially inward for making circumferential sealing contact with side surfaces of a human finger, said side wall distal end being sealingly joined to and closed by a distal end wall;
• wherein said enclosure shell encloses an interior space and wherein said interior space is at least partly filled with a solution said apparatus additionally comprising a sealing membrane extending across said interior space within said enclosure shell retaining said solvent;
• such that when a user fits a finger tip into said proximal end, the finger tip bears against and ruptures said sealing membrane and then enters, said interior space and is immersed in the solution, while side surfaces of the user finger simultaneously make sealing contact with said sealing structure.
