Abstract:
A catheter insertion device which employs back-and-forth longitudinal axial movement to advance the catheter by the cooperative interface of an incline ramp and a decline ramp with a split gripping mechanism is described.

Claim (Index 1):
A catheter insertion device which comprises:\n a substantially hollow housing having a longitudinal axis, the housing having a front and a rear and defining at least one upper longitudinal slot on an exterior of the housing;\n a first ramp positioned toward a rear of the at least one upper longitudinal slot, the first ramp having a decline for downward deflection; \n a second ramp positioned toward a front of the at least one upper longitudinal slot, the first ramp having an incline for upward deflection; \n the housing further defining a bottom longitudinal slot; \n an opposed pair of impingement surfaces toward a front of the housing to assist in preventing rearward movement of an inserted catheter tube; \n an advancement sleeve longitudinally insertable along the longitudinal axis of the housing into at least a portion of the housing from the rear, the advancement sleeve movable in a back-and-forth direction along the longitudinal axis of the housing, the advancement sleeve having a sleeve top, a sleeve bottom, a sleeve front and a sleeve rear; the advancement sleeve comprising:\n an inwardly and outwardly deflectable front top rail portion at the top front of the sleeve, the inward and outward deflection occurring transverse to the longitudinal axis of the advancement sleeve;\n a bottom rail on the advancement sleeve configured to fit into the bottom longitudinal slot of the housing; \n a laterally-extending expanded rear portion configured to stop forward movement of the advancement sleeve by contacting engagement with the rear of the housing; and \n an opposed pair of split tubing guides, at least one of the tubing guides moving interiorly in combination with downward defecting movement of the top rail upon impingement of at least a portion of the top rail with a decline ramp toward the rear of the at least one upper longitudinal slot to effect compression of a catheter tubing and upward deflecting movement of the top rail upon impingement of at least a portion of the top rail with an incline ramp toward the front of the at least one upper longitudinal slot to release the compression on the catheter tubing; \n \n an introducer tip affixed to the housing at the front;\n the introducer tip having a tip front and a tip rear; and \n the tip having at least one transverse slit in the tip front to permit egress of an inserted catheter.
