Abstract: A stable flow regulator assembly includes a body having an aperture that received a tube. The assembly also includes a worm gear that extends through, and is rotationally movable relative to, the body. A worm wheel is rotationally positioned within the body and is pivotably moved within the body by engagement with the worm gear. The worm wheel also includes a slot, configured to align with the aperture, through which a tube may be extended, and as the worm wheel is moved within the body, the slot and the aperture are moved out of and into alignment to compress and release compression upon the tube.

Abstract: Fluid connector systems including first and second connector portions couplable together to form a fluid pathway therethrough and can resist separation or permit separation as desired. A connector portion can include a connector housing and a cover portion. The connector housing includes a connector body and an engagement portion. The connector body defines a tubing opening and a mating opening. The connector body defines a flow path between the tubing opening and the mating opening. The engagement portion at least partially surrounds the connector body. The engagement portion defines an engagement lip extending radially toward the connector body and is configured to releasably engage the connector housing. The flow path includes at least one portion that is normal to the engagement portion. Fluid flow through the flow path exerts a normal force on the connector housing and prevent release of the connector housing with the mating connector portion.

Abstract: Fluid connector systems including first and second connector portions couplable together to form a fluid pathway therethrough and can selectively resist or permit separation as desired. A connector portion can include a connector housing and a cover portion. The connector housing includes a connector body and an engagement portion. The connector body defines a housing volume, a luer opening and a mating opening. The housing volume is in fluid communication with the luer opening and the mating opening. The engagement portion may include an engagement lip extending radially toward the connector body. The engagement lip is configured to releasably engage the connector housing with a mating connector portion. The cover portion is configured to selectively surround the engagement portion of the connector housing. The cover portion is slidable to engage with the engagement portion of the connector housing and prevent release of the connector housing with the mating connector portion.

Abstract: Fluid connectors assemblies that provide neutral fluid displacement are disclosed. A fluid connector assembly may include first member and a second member. A deformable sleeve is located on a post of the second member. A septum is located on an opening of the first member. The first member and the second member each include an opening. The sleeve can seal off the opening of the post from fluid entry. However, when the post of the second member is inserted into the first member, a septum of the first member displaces a sleeve of the second member, causing the sleeve to uncover the opening. Further, the septum seals each of the first member and the second member and the displaced sleeve forms a fluid path through the first and second member, with the sleeve regulating fluid flow.

Abstract: A disinfection device for disinfecting a female medical connector. The device includes an inner housing having an absorbent material that includes a disinfectant or antimicrobial agent that receives the connector. The device also includes an outer housing having an outer wall that receives the inner housing wherein the inner housing is rotatable within the outer housing. An indicator is located between the outer wall and a transparent collar that includes at least one rib. The indicator includes a first visual indicator and a second visual indicator concealed by the first visual indicator. The inner housing includes a boss element that extends through the outer wall and indicator and is attached to the collar. Rotation of the collar causes rotation of the absorbent material and causes the rib to remove sufficient portions of the indicator to expose the second visual indicator to provide visual indication that the connector is disinfected.

Abstract: A first venous rhythm of a patient is detected above a venous insertion site when a venous catheter connected to an infusion set is inserted into the venous insertion site and, concurrently with the first venous rhythm, a second venous rhythm is detected at a location remote from the venous insertion site. An irregularity between the first and second venous rhythms is identified, and a failure of the venous catheter is determined based on the identified irregularity satisfying a irregularity threshold. An alarm may be provided on detecting the irregularity or the failure of the venous catheter.

Abstract: A flow regulation clamp assembly for adjusting the fluid flow rate in a connector tube of an infusion set is provided. The flow regulation clamp assembly includes a housing to receive the connector tube, a slider slideably engaged within the housing and configured to compress the connector tube to provide a fluid flow adjustment, and a rotator knob moveable engaged with the housing and configured to move the slider. Infusion sets and methods of adjusting fluid flow rates are also provided.
