Abstract: A flow sensor sub-assembly for sensing flow of a fluidic medicament includes a flow tube having a flow tube inlet and a flow tube outlet, and an acoustical transmission rate. The medicament flows through the flow tube. A first piezo element is arranged at an upstream position of the flow tube and a second piezo element is arranged at a downstream position of the flow tube, such that the first piezo element and the second piezo element are mounted apart a pre-selected distance from each other. An absorber sheath encircles the flow tube. The absorber sheath has an upstream end and a downstream end. The absorber sheath is comprised of a material with an acoustical transmission rate different than the flow tube.

Abstract: A metal mold includes a restraining part that is fitted in a recess provided at a part of surfaces of at least two resin parts that serves as an outer surface of a resin hollow body. A linear space is filled with high-pressure resin fluid injected at a predetermined injection pressure. The resin parts are joined together. The mold receives injection pressure of resin fluid, with which the space is filled, through the resin parts, and applies pressing force, which pushes back the resin parts toward the space, to the resin parts as reaction force against injection pressure. Stress is produced on a hollow wall surface in a direction in which the wall surface projects into a hollow portion due to injection pressure. The restraining part applies pressing force to the resin parts in a direction opposite from the stress projecting the wall surface into the hollow portion.
