摘要： A flow restriction device may include a distal end configured to couple to a catheter assembly, a proximal end configured to couple to a fluid collection device, and a body extending from the proximal end to the distal end. The body may include an outer surface and an inner surface defining a lumen of the body. The flow restriction device may further include a fluid pathway disposed between the distal end and the proximal end when the outer surface is coupled within a mating luer. The fluid pathway may include a non-linear portion on at least a portion of the outer surface along which a fluid flows from the distal end into the fluid collection device.

摘要： A flow restriction device may include a male luer connector portion, a female luer connector portion disposed proximally to the male luer connector portion, and a body portion extending between the male and female luer portions, and integrally formed with the male and female luer portions to form a single monolithic piece. The male luer connector portion may have an internal surface defining a lumen thereof, and the female luer connector portion may have an internal surface defining a lumen fluidly connected to the lumen of the male luer connector portion. The body portion may have a recess extending longitudinally therethrough and fluidly communicated with the lumens of the male luer portion and the female luer portion. The recess may define a micro-channel along which fluid flows from the male luer connector portion into the fluid collection device via the female luer connector portion.

摘要： A pump device includes a pump driver comprising a first diaphragm and a second diaphragm, the first and second diaphragms each comprising a middle portion bounded by an outer portion, the first and second diaphragms being spatially separated from each other at the respective outer portions, and coupled together at the respective middle portions. The pump also includes a fluid passageway and a pump chamber fluidly connected to the fluid passageway, wherein the pump chamber comprises a moveable wall coupled to the pump driver at the middle portions of the first and second diaphragms such that a fluid movement between the pump chamber and the fluid passageway is induced by movement of the middle portions. An input device is configured to obtain a target flow rate. A controller is configured to operate the pump driver and a flow regulator based on signals received from a flow detector.

摘要： Check valves are described herein. A check valve includes an inlet body, an outlet body, a valve body, a valve member, and a wiping extension. The inlet body defines an inlet portion. The outlet body defines an outlet portion. The valve body is coupled between the inlet bod and the outlet body. The valve body defines a valve cavity. The valve cavity is in fluid communication with the inlet portion and the outlet portion. The valve member is disposed within the valve cavity. The valve member is configured to permit flow from the inlet portion to the outlet portion and prevent flow from the outlet portion to the inlet portion. The wiping extension extends from the valve body toward the valve member. The wiping extension is movable relative to the valve member to dislodge particulate from the valve member.

摘要： Systems and methods for determining the position of a fluid within a fluid source and infusion line coupled to an infusion flow control device are described herein. An exemplary system and method includes sampling fluid pressure upstream of an infusion pump, and calculating fluid pressure slope profiles. By sampling fluid pressure upstream of an infusion pump at discrete intervals and monitoring fluid pressure slope profiles, conditions of fluid flow, including unintentional fluid flow through an infusion line or a defective check valve in an infusion line, are detected, and fluid flow through an infusion pump is controlled.

摘要： A method for detecting diversion may include identifying an activity pattern associated with a clinician as being an infrequent activity pattern that occurs below a threshold frequency. Whether the infrequent activity pattern corresponds to an anomalous behavior may be determined based at least on one or more data models. The infrequent activity pattern may include a series of transaction records, which may be matched to the reference transaction values included in each of the one or more data models. An investigative workflow may be triggered in response to the infrequent activity pattern being determined to correspond to the anomalous behavior. Related methods and articles of manufacture are also disclosed.

摘要： A medication dispensing cabinet includes one or more lockable compartments, each containing medication, and a biometric input device at least partially disposed within and recessed below a surface of a medication dispensing cabinet. A compartment containing the medication is unlocked when an authorized biometric input is received by the biometric input device. The medication dispensing cabinet may verify that the user attempting access to the medication is authorized to dispense the medication before unlocking the compartment.

摘要： A needleless connector may include a housing comprising a central longitudinal axis, a body portion, and a base portion. The body portion may include an inner surface forming an internal cavity, and a first port forming a first fluid passage to the internal cavity. The base portion may include a top section including a valve seal support, and a bottom section including a second port forming a second fluid passage to the internal cavity. The needleless connector may further include an asymmetrically-shaped valve disposed in the internal cavity. The asymmetrically-shaped valve may include a head portion, a valve body portion extending distally from the head portion, and a wall having an inner surface forming a valve cavity. The valve may be coupled with the housing such that the inner surface of the valve at the valve body portion is seated and radially supported on the valve seal support.

摘要： 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.
