Abstract
Abstract A dispenser comprising a base and a reel rotatably mounted on the base. An elongated flexible member which is to be dispensed is wound on the reel, and a housing is provided for the reel and the flexible member. Interlocking members on the reel and the housing hold the reel against rotation in any direction in the housing until the housing is removed from the base. The reel has first and second sets of radially extending fingers at the periphery of the reel, with the first set of fingers being inclined relative to the second set of fingers. The flexible member is wound on the reel between the first and second sets of fingers.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
123 words
A dispenser comprising: a base; a reel, means for mounting the reel on the base for rotation relative to the base, an elongated, flexible member to be dispensed wound on said reel, said flexible member being adapted for insertion into a patient; housing means for forming a sterile enclosure for the reel and the flexible member, said housing means being removable from the base; and cooperating means on the reel and the housing means for holding the reel against rotation in said enclosure in both directions, said cooperating means being responsive to the removal of the housing means from the base to release the reel for rotation only when said housing is removed from said base whereby the flexible member can be dispensed.
Claim 2
Dependent Claim
123 words
A dispenser comprising: a base; a reel, means for mounting the reel on the base for rotation relative to the base, an elongated, flexible member to be dispensed wound on said reel, said flexible member being adapted for insertion into a patient; housing means for forming a sterile enclosure for the reel and the flexible member, said housing means being removable from the base; and cooperating means on the reel and the housing means for holding the reel against rotation in said enclosure in both directions, said cooperating means being responsive to the removal of the housing means from the base to release the reel for rotation only when said housing is removed from said base whereby the flexible member can be dispensed.
