Abstract: A valve for controlling delivery of fluid includes a valve seat comprising a fluid inlet, a fluid outlet, a well having a passage, and a valve membrane comprising a conical portion having a base and a tip. The conical portion is configured to fit within the passage of the valve seat. The valve membrane is configured to fluidly connect the fluid inlet to the fluid outlet when the valve membrane is in an undeformed position and fluidly disconnect the fluid inlet from the fluid outlet when the valve membrane is in a radially deformed position.

Abstract: A pumping mechanism is disclosed that includes a plurality of peristaltic pumping actuators configured to selectively and sequentially compress adjacent portions of a first portion of an at least partially compressible pumping element having an inlet that is upstream of an outlet. The plurality of pumping actuators are further configured to reciprocate at a common drive frequency with a first phase offset between each adjacent pair of pumping actuators. The pumping mechanism also includes at least one compensation actuator arranged to selectively compress a second portion of the at least partially compressible pumping element that is disposed between the first portion and the outlet. The at least one compensation actuator is configured to reciprocate at an optimal displacement and at a modulation frequency that is an integer multiple of the fundamental drive frequency and with a second phase offset between the at least one compensation actuator and the adjacent pumping actuator.

Abstract: An apparatus method, and system for detecting a leaking occluder valve is disclosed. At least one measurement instrument is connected to a fluid within a fluid tubing upstream or downstream of a pump element of an infusion device. The pump element is configured to periodically cause a compression of the fluid tubing and to isolate a downstream portion of the fluid tubing from an upstream portion of the fluid tubing when the pump element is operating under a normal operating condition. A response of the fluid is measured when the pump element is caused to compress the fluid tubing and a determination is made, based on the response whether the compression has fluidically isolated the downstream portion from the upstream portion. One or more shims may be inserted into the occluder valve to move the platen away from the pump element during the test to determine a degree of fault.

Abstract: A method may include capturing, by a camera at an infusion pump, one or more images of the pump loaded with an infusion set. A machine learning model may be applied to the images to detect nonconformities that may be present in the images of the pump loaded with the infusion set. Examples of nonconformities include a misload of the intravenous set in which an upper fitment, a lower fitment, and/or a tubing of the intravenous set is misplaced within the pump. In response to an output of the machine learning model indicating a presence of a nonconformity in the one or more images of the pump loaded with the infusion set, a corrective action may be performed. For example, the pump may be prevented from performing an infusion and a message identifying the nonconformities may be generated. Related methods and articles of manufacture are also disclosed.

Abstract: 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.

Abstract: A syringe pump can be operated to produce fluid flow from a syringe installed therein. Features of the pump can produce a desired rapid commencement of flow followed by smooth delivery uninterrupted by stiction-induced slowing and acceleration. A stiff drivetrain can facilitate detection of excessive forces indicative of friction at a stopper-wall interface. The motor drive, gearing, and control parameters can enable customized acceleration patterns to determine optimal initial stage advancement to provide fluid delivery. These patterns can minimize or eliminate the delay in commencement of flow by overcoming both mechanical slack remaining and syringe stopper slack. To avoid flow irregularities produced by stiction forces in the stopper further, a mechanical vibration can be provided to the syringe and/or barrel to introduce movement of the stopper-wall interface, reducing the creation of high static friction coefficients.

Abstract: Systems and methods are provided for intermittent microinfusion. A system may include a pump and an IV set that includes a y-port valve disposed below a pump interface portion of the IV tubing. The y-port valve may include an internal valve member that allows fluid to flow from the pump to a patient when no syringe is attached to the y-port. The internal valve member may be moved by the attachment of a syringe containing the medication to be infused to the y-port such that the fluid pathway from the pump to the patient is blocked and fluid from the syringe can be injected into the IV tubing between the y-port valve and the pump. The pump may retrograde pump the medication into the tubing via the y-port valve and then forward pump the medication to the patient when the syringe is removed from the y-port.
