Patent number: 9199062Abstract: An inserter assembly for a peripheral catheter assembly configured with an adhesive plaster member, wherein the catheter tube extends through the plaster member. The inserter assembly includes a first inserter part having first and second legs, a bridge member connecting the first and second legs at a distance from each other, with the bridge member adapted for detachably engaging or holding at least a part of the needle module extending coaxially between the first and second legs. The inserter assembly includes a second inserter part for covering the needle. The plaster member impairs visual sight and the line of vision to the needle tip during puncture may be impaired.
