Abstract: An improved device for simple and reliable control of flow through a medical infusion line, one end of the medical infusion line having a fluid conveying pump provided on it and the other end assigned to a patient, the infusion line forming a main flow path from the fluid conveying pump to the patient-side end. Fluid is conveyed along the main flow path through the infusion line by means of the fluid conveying pump. At least a part of the fluid is introduced, along a measurement flow path branching off from the main flow path at a branching point, from the infusion line into a measurement reservoir connected to the infusion line. The infusion line includes a fluid restrictor between the fluid conveying pump and the branching point, and the main flow path as viewed in direction of the flow is interrupted after the branching point of the measurement flow path for filling the measurement reservoir by the pressure of the fluid conveying pump. The fluid in the measurement reservoir is detected.

A flow regulator can be positioned inside the catheter hub. The flow regulator can include a stem and a sleeve.

Abstract: Needle devices are disclosed in which a needle having a wall defining a needle lumen has a notch (120) formed through the wall. A transparent or semi-opaque window cover (130) made from a biocompatible material is provided over the notch. Blood flow through the needle lumen can be viewed through the notch with the window cover. The needle with the notch and window cover may be used with a variety of needle applications, including as catheter assemblies, indwelling assemblies, and most if not all over-the-needle type devices.

Abstract: The present disclosure relates to a set for producing a threaded connection, comprising a first and a second tubular component with an axis of revolution, one of their ends being provided with a threaded zone formed on the external or internal peripheral surface of the component depending on whether the threaded end is of the male or female type, said ends finishing in a terminal surface which is oriented radially with respect to the axis of revolution of the tubular components, a thread crest, a thread root, a load flank and a stabbing flank, the width of the thread crests of each tubular component reducing in the direction of the terminal surface of the tubular component under consideration, while the width of the thread roots increases, characterized in that the lead of the male stabbing flanks and/or load flanks is different from the lead of the female stabbing flanks and/or load flanks. The present method, system and device also pertain to a threaded connection.
