The present invention relates to a flushing catheter device, flushing catheter components, and methods for making the same. A flushing catheter includes one or more flush segments comprised of one or more flush ports along a length of catheter body. A preferred method for making a flushing catheter incorporates a retrofit including one or more flush segments. Flushing catheters may be nested within each other's lumens to form a multi-catheter system. Flush segments may enable radial fluid communication between the many lumens and annular lumens of a multi-catheter system, e.g. intraluminal fluid communication. A multi-catheter system including flushing catheters may be entirely purged of air with a single step of fluid injection. A flushing catheter may include a tapered distal end to further enhance the ease of procedure with a multi-catheter system.

Embodiments of the invention are directed to flush syringe assemblies comprising an integrated contamination-prevention device integrated with device connector flushing positioned so that the practitioner cannot forget to apply disinfectant. The flush syringe assemblies comprise a barrel with an elongate plunger rod disposed therein and a cap comprising a passageway. The plunger rod includes a stopper of which at least a portion can be embedded in the passageway of the cap to form a plug in the cap.

Valves and medication delivery systems including valves are described herein. A valve includes a valve body and a valve element. The valve body defines a first flow path, a second flow path, and a catheter flow path. The valve element is disposed within the valve body, wherein the valve element is configured to permit fluid communication between the first flow path and the second flow path in a priming position, and is configured to permit fluid communication between the first flow path and the catheter flow path in a dispensing position.

A flushing apparatus according to embodiments of the present disclosure includes: a main body configured to connect a connection pipe for guiding a hazardous medicinal liquid harmful to a human body when exposed to an ambient air and a patient connection module for injecting the hazardous medicinal liquid into a patient, the main body configured to form a first flow path for guiding the hazardous medicinal liquid from the connection pipe to the patient connection module, the main body including a flushing portion forming a second flow path connected to a predetermined connection point located between both ends of the first flow path; and a flow rate reduction part disposed at upstream side of the connection point in the first flow path and configured to reduce a flow rate of the hazardous medicinal liquid flowing through the first flow path. The present disclosure shows various embodiments of the flushing apparatus.

An introduction of medical tools to this invention that enables the improvement of flushing of sterile solutions, medications and the collection of blood specimen(s). In addition, an introduction of intravenous system whereby the healthcare provider can perform the tasks of flushing the intravenous site efficiently and collecting blood specimen using the combination of medical tools. Most importantly, these tools included in this invention preserve and protect intravenous lines from malfunctioning.

Syringe assemblies comprising a disinfecting reservoir collar to ensure an adherence to aseptic techniques for use in flush procedures for vascular access devices (VAD's) are described. Also described are methods of disinfecting the vascular access devices.

A retrograde disposable intravenous (IV) set is disclosed. The IV set includes a diverter housing between upper and lower portions of a fluid line, the diverter housing including a lower end and an upper end extending away from the lower end and the fluid line to a syringe port located in the upper end, and a diverter member within the diverter housing and configured to move within the diverter housing from a first position, at which a first opening through the diverter member forms a first fluid pathway between the upper portion and the lower portion of the fluid line, to a second position, at which the first fluid pathway is blocked and a second fluid pathway is formed between the upper portion of the fluid line and a syringe port. Retrograde infusion may occur when the diverter member is in the second position.

A flush device may be used to flush a catheter system. The flush device may include a housing, a proximal connector coupled to the housing, and a distal connector coupled to the housing. The flush device may include a first conduit disposed within the housing and extending between the proximal connector and the distal connector. The flush device may include a second conduit disposed within the housing and in fluid communication with the first conduit. The flush device may include a fluid reservoir, which may be disposed within the housing of the flush device. The flush device may include a pump that pumps fluid from the fluid reservoir, through the second conduit, and into the first conduit. The device may include a one-way valve, which may prevent fluid from flowing beyond the one-way valve toward the fluid reservoir.

Systems and methods are provided herein that generally involve shunting fluid, e.g., shunting cerebrospinal fluid in the treatment of hydrocephalus. Self-cleaning catheters are provided which include split tips configured such that pulsatile flow of fluid in a cavity in which the catheter is inserted can cause the tips to strike one another and thereby clear obstructions. Catheters with built-in flow indicators are also provided. Exemplary flow indicators include projections that extend radially inward from the interior surface of the catheter and which include imagable portions (e.g., portions which are visible under magnetic resonance imaging (MRI)). Movement of the flow indicators caused by fluid flowing through the catheter can be detected using MRI, thereby providing a reliable indication as to whether the catheter is partially or completely blocked. Systems and methods for flushing a shunt system are also disclosed herein, as are various systems and methods for opening auxiliary fluid pathways through a shunt system.

A fluid delivery system includes a first container configured for storing a first fluid therein and a second container configured for storing a second fluid therein, wherein the second fluid is different from the first fluid. The fluid delivery system further includes at least one pump configured for delivering under pressure one or both of the first and second fluids. At least one valve is provided for selectively delivering one or both of the first and second fluids to the pump. The first and second containers, the pump, and the valve are contained within a cartridge that is removably insertable into a cartridge carrier of the fluid delivery system.
