A medicinal liquid flow control apparatus includes a medicinal liquid flow path that guides a flow of a medicinal liquid. The medicinal liquid flow path includes an inlet flow path through which the medicinal liquid is introduced, a plurality of branch flow paths branching from the inlet flow path, and an outlet flow path to which the plurality of branch flow paths join and through which the medicinal liquid flows out. The medicinal liquid flow control apparatus includes a plurality of transfer tubes configured to correspond to the plurality of branch flow paths, respectively, each of the transfer tubes forming a capillary flow path constituting at least a portion of a corresponding one of the plurality of branch flow paths, and a valve configured to control a flow rate of the medicinal liquid flowing out through the outlet flow path by selectively opening and closing the plurality of branch flow paths.

OVERMOLDED CONNECTORS FOR TUBING

Tubing systems are described herein. A tubing system can include a tubing assembly, a tubing system component, and a coupling portion. The tubing assembly includes a tubing and a tubing assembly connector coupled to the tubing. The tubing assembly connector defines a connector lumen in fluid communication with the tubing lumen. The tubing assembly connector has a tubing assembly connector elastic modulus greater than the tubing elastic modulus. The tubing system component has a component connector abutted against the tubing assembly connector. The component connector has a component connector elastic modulus greater than the tubing elastic modulus. The coupling portion is overmolded over the tubing assembly connector and the component connector to couple the tubing to the tubing system component.

Multi-line opposed inlet infusion coupling
11491319 · 2022-11-08 ·

An infusion coupling allows administration of IV drugs to a patient through an IV fluid line, and ensures that successive courses of medication are fully passed or flushed from the line to prevent mixing of incompatible drugs in the IV line. The infusion coupling includes a vessel body, and a plurality of branch inlets to receive medication through IV tubing connected to the inlets. The vessel body has a generally cylindrical shape such that each of the branch inlets is in fluidic communication with the interior volume for receiving the IV fluids for transport. The inlets are angled on the body of the infusion coupling. A transverse bar or obstruction extends across an interior diameter of the infusion coupling for disrupting a circular flow that can result in a vortex. Formation of a vortex can retain the infused medication in the infusion coupling and result in mixing with successive medication courses.

Ambulatory device and components thereof

Certain embodiments provide multi-medicament or single medicament infusion systems for preventing the cross-channeling or improper delivery of medicaments. The system may include one or more of an infusion pump, medicament cartridges, cartridge connectors, a multi-channel fluid conduit, and an infusion set. The medicament cartridges may be sized and shaped differently such that the medicament reservoirs can only be inserted into the pump under selected configurations.

Compact Insertion Assemblies of Rapidly Insertable Central Catheters and Methods Thereof

Disclosed are compact rapidly insertable central catheter (“RICC”) insertion assemblies and methods. For example, a RICC insertion assembly can include a RICC, an introducer assembly, an access guidewire, and a coupler coupling together the RICC and the introducer assembly. The RICC can include a catheter tube, a catheter hub, and one or more extension legs connected in the foregoing order. The introducer assembly can include an introducer needle coupled to a syringe. The introducer needle can include a needle-hub through hole passing through a needle hub and connecting to a needle-shaft lumen of a needle shaft. The access guidewire can include a proximal portion disposed in the RICC and a distal portion disposed in the needle-shaft lumen through the needle-hub through hole. The coupler can enforce a loop in the access guidewire over which the catheter tube follows, thereby compacting the RICC insertion assembly and making it easier to handle.

INTRODUCER SHEATH ASSEMBLY AND METHOD OF MAKING THE SAME
20230094090 · 2023-03-30 ·
