Catheter placement unit with resilient sleeve and manual sleeve closure

Claim 1

A catheter assembly comprising: a catheter tube having an axial bore; elongated piercing means coaxially disposed through and extending beyond the leading end of the axial bore of the catheter tube; a female hub on the trailing end of the catheter tube; a resilient sleeve member disposed within the female hub and having a bore therethrough through which the piercing means contiguously passes prior to venipuncture; mechanical means disposed on the female hub in radial alignment with the site where the piercing means and the resilient sleeve member are contiguous, the mechanical means comprising movable means and opposed pressure applying means associated with the said hub and resilient sleeve number whereby selective movement of the movable means manually repositions the pressure applying means, before or after venipuncture and removal of the piercing means, to constrict the resilient member at said site to fully occlude any passageway in the resilient member at said site thereby preventing fluid leakage across the resilient member and opposed locking means retaining the movable means in said occluding position.
