High accuracy clamp assembly

A clamp assembly comprising:

• a housing configured to couple to an infusion set, the housing comprising:
• two opposing side walls spaced apart from each other, each side wall having an opposing guide track longitudinally positioned in an interior surface;
• a guide wall disposed between the side walls;
• an elastomeric membrane disposed on the guide wall between the two opposing side walls, the elastomeric membrane having a lower compression set performance that the compression set performance of first and second intravenous (IV) tubes of the infusion set;
• a first tubing port disposed on a first end of the elastomeric membrane and configured to couple with the first IV tube of the infusion set;
• and
• a second tubing port disposed on a second end of the elastomeric membrane and configured to couple with the second IV tube of the infusion set;
• and
• a flow-regulating member having two portions slidingly seated in the guide tracks, the flow-regulating member configured to move along a longitudinal axis of the housing over a movement range as the two portions slide in the guide tracks,
• wherein the flow-regulating member is configured to remain in a set position during use of the infusion set based on the compression set performance of the elastomeric membrane until the flow-regulating member is moved by a user,
• wherein the flow-regulating member comprises a geared slider having two axial projections slidingly seated in the guide tracks, and wherein a portion of the geared slider extends above a top surface of the housing,
• wherein the elastomeric membrane is overmolded into the housing and comprises an enclosed fluid pathway between the first and second tubing ports, and
• wherein the elastomeric membrane comprises gear protrusions disposed on a non-fluid path surface opposing the geared slider, the gear protrusions configured to mesh with the geared slider.
