摘要: 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 imageable 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.

摘要: A method and medical pump to perform a flushing procedure are provided. The medical pump is configured to execute the flushing procedure subsequent to an infusion procedure, the flushing procedure and infusion procedure lacking a specified relationship between each other until after performance of the infusion procedure. The method comprises performing an infusion procedure of a medicament with the medical pump and automatically querying in human detectable form whether to execute a flushing procedure in response to conclusion of the infusion procedure.

摘要: An injector head with rotation mechanism allows selection between a state in which a syringe assumes a priming orientation with a through hole of the syringe positioned upper than the injector head body, and a state in which the syringe assumes a contrast agent injectable orientation with the through hole of the syringe positioned lower than the injector head body.

摘要: A device for priming and venting a hazardous drug within an intravenous administration set. The device includes various access ports and fluid channels to permit direct injection of a hazardous drug into the fluid reservoir, while eliminating the possibility of undesirable exposure to the hazardous drug. The device further includes priming and flushing ports to enable flushing of a hazardous drug from the system following an infusion procedure.

摘要: A medical placeholder. The medical placeholder has at least one hollow body which is expandable and which defines an interior space, a gas infeed hose which is connected or connectable in a gas-permeable manner with the interior space of the hollow body, and a gas discharge hose which is connected or connectable in a gas-permeable manner with the interior space of the hollow body. The hollow body consists partly or completely of at least one plastic material which is permeable to oxygen and carbon dioxide. A one-way valve is arranged in the gas infeed hose and a pressure relief valve is arranged in the gas discharge hose. Also disclosed is a method for gas-flushing a surface of a medical placeholder.

摘要: Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.
