Cartridges, dispensers, and kits for dispensing instrument covers

A kit comprising a dispenser and a cassette for automatic touch-free dispensing of disposable instrument covers onto an instrument, the cassette comprising:

• a supply spool configured to hold a backing member having the disposable instrument covers disposed thereon;
• a tape spool configured to hold spent backing member without the disposable instrument covers disposed thereon, the tape spool spaced apart from the supply spool to define a flat area of the backing member disposed between the supply and tape spools, wherein the flat area further comprises a resistance section, the resistance section comprising a parallel section attached directly to the cartridge by way of perpendicular edges, thereby forming a space between the backing member and the resistance section, wherein the supply and tape spools are configured to rotate such that the disposable instrument covers are exposed through a cassette window positioned at a front face of the cassette;
• a peeler pin positioned proximate to the supply spool to change direction of a path of the backing member to partially separate the disposable instrument covers from the backing member to ease the transfer of the disposable instrument cover onto the instrument;
• and
• a dispenser housing with a lid configured to house the cassette, the dispenser housing comprising an access window configured to permit insertion of the instrument therethrough to permit coupling of the instrument to the disposable instrument cover exposed at the access window and positioned at the flat area of the backing member,
• wherein the supply and tape spools are configured to rotate such that the disposable instrument covers are exposed through the access window, wherein the cassette comprises a lid and separate spool structures to interface with the supply spool and the tape spool within the cassette.
