The present teachings may generally include a first fluid connector that includes a first body having a first central cavity that defines a first fluid pathway and a first seal within the first central cavity. The first seal includes a pair of first interfacing elements positioned adjacent one another at a distal end of the first seal and a first opening configured to remain sealed closed when the first interfacing elements are adjacent, and the first opening opens when the first interfacing elements are separated. The first connector is configured to fluidly connect to a second connector by engaging the first interfacing elements and with a pair of second interfacing elements of the second connector, thereby causing both pairs of first and second interfacing elements to separate causing the opening of first opening and second opening.

Self-sealing fluid connectors

A medical fluid line connector includes a body defining a central opening extending therethrough, a first projection extending from a first portion of the body, and a second projection extending from a second portion of the body, the second projection being circumferentially and axially offset from the first projection. The first portion of the body and second portion of the body are configured to separate from one another in response to a threshold amount of force being applied to the first projection and the second projection to rotate the first portion of the body and second portion of the body relative to one another.

Medical fluid line connection devices

The present teachings include techniques for securing a connection to a dialyzer or the like—e.g., securing the junction between a dialyzer port and a connector (e.g., a DIN connector) that couples the port to tubing of an extracorporeal circuit of a hemodialysis system. To this end, a locking device may engage both a DIN connector and a portion of the dialyzer, such as the cap or an adapter engaged therewith. The locking device may include an interior void sized and shaped to accommodate winged portions (or other portions) of the DIN connector to mitigate rotation thereof relative to the port to which it is engaged. Further, the locking device may be used to ensure that coupling between the DIN connector and the port is proper and secure. In this manner, a locking device can mitigate leaks, which can be catastrophic during a hemodialysis treatment or the like.

Securing connections to dialyzers

This disclosure relates to symmetric tubing clamps for blood treatment systems and related systems and methods. In some aspects, a tubing clamp includes a resilient body that has symmetry with respect to a first plane with a normal along a longitudinal axis of the resilient body, the resilient body comprising a sidewall defining an opening such that a tubing is arrangeable through the opening along the longitudinal axis of the resilient body; first and second snap-fit features configured to engage with each other when the resilient body is compressed along a direction transverse to the longitudinal axis; and a protrusion configured to constrict the tubing when the resilient body is compressed along the direction transverse to the longitudinal axis.

Flexible medical container

This disclosure relates to systems for supporting medical fluid bags and related methods. In some implementations, a system includes a curved tray configured to support a medical fluid bag during a medical treatment, the curved tray including a plurality of openings therethrough, a medical fluid collection basin removably coupled to the curved tray and configured to collect medical fluid leaked from the medical fluid bag during the medical treatment, a leak detector coupled to a surface of the medical fluid collection basin and configured to detect fluid as leaked from the medical fluid bag into the medical fluid collection basin, and a control unit configured to receive treatment data related to the medical treatment.

Systems for supporting medical fluid bags and related methods

A mechanical lift includes a housing defining a series of vertical adjustment notches, an adjustment block disposed within the housing, a hook extending from the adjustment block and configured to support a hanging load, a stopper supported by the adjustment block and movable between retracted and extended positions, and a spring disposed within the housing and exerting an upward force against the adjustment block to mechanically lift the adjustment block and the hook extending therefrom from a first vertical position at a first notch of the series of vertical adjustment notches to a second notch of the series of vertical adjustment notches when the stopper is in the retracted position. In the retracted position, the stopper is disengaged from the housing. In the extended position, the stopper is engaged with a selected notch to lock a vertical position of the adjustment block and the hook extending therefrom.

The disclosed arterial chambers for hemodialysis may include a cap with a blood inlet port for conveying an intended patient's blood into the arterial chamber, an auxiliary port configured to provide fluid access to the arterial chamber, and a needleless access port configured to couple to a needleless syringe. The needleless access port may be configured for administering a substance to an interior of the arterial chamber from the needleless syringe and/or for withdrawing blood from the interior of the arterial chamber into the needleless syringe. Various tubing sets, hemodialysis systems, and other components, systems, and methods are also disclosed.

The disclosed packaging bags may include a flexible front sidewall and a flexible rear sidewall with at least a first closed edge, second closed edge, and third closed edge coupling the front sidewall to the rear sidewall. A perforation may be formed through the flexible front sidewall and the flexible rear sidewall along the first closed edge. The perforation may extend in a first segment from the first closed edge toward a central region of the packaging bag, in a second segment in a direction along the first closed edge, and in a third segment back to the first closed edge. The second segment may include at least one elongated ventilation slit. Various other related packaging bags and methods are also disclosed.
