摘要： To detect air in a fluid delivery line of an infusion system, infusion fluid is pumped through a fluid delivery line adjacent to at least one sensor. A signal is transmitted and received using the at least one sensor into and from the fluid delivery line. The at least one sensor is operated, using at least one processor, at a modified frequency which is different than a resonant frequency of the at least one sensor to reduce an amplitude of an output of the signal transmitted from the at least one sensor to a level which is lower than a saturation level of the analog-to-digital converter to avoid over-saturating the analog-to-digital converter. The signal received by the at least one sensor is converted from analog to digital using an analog-to-digital converter. The at least one processor determines whether air is in the fluid delivery line based on the converted digital signal.

摘要： Bubble traps for use in medical fluid lines and medical fluid bubble trap systems are disclosed herein. In some embodiments, the bubble trap is configured to trap gas (e.g., air) that flows into the bubble trap from a fluid line. In some embodiments, the bubble trap includes an inlet and an outlet and a chamber between the inlet and the outlet. For example, in some embodiments, the bubble trap is configured to inhibit gas from flowing into the outlet once gas flows into the chamber from the inlet. In some embodiments, the bubble trap is in fluid communication with a source container, a destination container, and/or a patient.

摘要： In one step of a method for infusing an infusion fluid, the infusion fluid is pumped through a fluid delivery line of an infusion system. In another step, measurements are taken with at least one sensor connected to the infusion system. In an additional step, an air determination is determined with at least one processor. The air determination is related to air in the fluid delivery line. The air determination is based on the measurements taken by the at least one sensor. The air determination is further based on: (1) medication information regarding the infusion fluid or infusion information regarding the infusion of the infusion fluid; or (2) multi-channel filtering of the measurements from the at least one sensor or non-linear mapping of the measurements from the at least one sensor; and statistical process control charts applied to the multi-channel filtered measurements or applied to the non-linear mapped measurements.

摘要： A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.

摘要： A system and method are provided for detecting air embolisms in lines for hemodynamic monitoring. In use, using a first sensor, one or more gas bubbles are detected within a first line for hemodynamic monitoring. In response to the detecting, a first clamp attached to the first line for hemodynamic monitoring is contracted.

摘要： A gas elimination apparatus and a method for use in an intravenous delivery system are provided. The apparatus includes in a fluid inlet coupling a fluid flow into a liquid chamber, a fluid outlet protruding into the liquid chamber, and a flow diversion member proximal to the fluid outlet. The flow diversion member configured to block a direct flow between the fluid inlet and the fluid outlet. The apparatus includes a membrane separating a portion of the liquid chamber from an outer chamber and a gas venting valve fluidically coupling the outer chamber with the atmosphere. The flow diversion member may be mechanically supported by at least one strut or elongate member extending along a flow direction into the liquid chamber.
