Securing connections to dialyzers

A device for securing a connection to a dialyzer, the device comprising:

• a housing including a top surface, a bottom surface, and a side portion disposed between the top surface and the bottom surface;
• a cutout disposed through the housing from the top surface to the bottom surface, the cutout at the bottom surface sized and shaped to accommodate a port of a dialyzer, and the cutout at the top surface sized and shaped to accommodate one or more of (i) an outer diameter of tubing of an extracorporeal circuit of a dialysis system, and (ii) an outer diameter of a first end of a connector configured to couple the tubing to the port of the dialyzer, wherein a second end of the connector is configured to releasably secure the connector to the port of the dialyzer;
• an interior void within the side portion between the top surface and the bottom surface of the housing, the interior void having a maximum diameter larger than a maximum width of the cutout, the interior void sized and shaped to accommodate winged portions disposed between the first and second ends of the connector;
• and
• a first engagement portion disposed on the bottom surface of the housing, the first engagement portion structurally configured to slidably couple to a second engagement portion disposed on an end of the dialyzer that includes the port such that, when coupled, the connector is at least partially disposed within the interior void and the winged portions of the connector are mitigated from rotating relative to the end of the dialyzer thereby securing the connector in a substantially fixed rotational position.

A method, comprising:

• releasably securing a connector to a port of a dialyzer such that the connector is in a predetermined position relative to the port, the connector having one or more winged portions disposed between first and second ends thereof;
• and
• engaging a locking device with at least one of the port and the connector by:
• coupling a first engagement portion disposed on a bottom surface of the locking device to a second engagement portion disposed on an end of the dialyzer that includes the port, the second engagement portion separate from the port;
• and
• receiving at least a portion of the one or more winged portions of the connector within an interior void of a housing of the locking device.

A system, comprising:

• a locking device, comprising:
• a housing including a top surface, a bottom surface, and a side portion disposed between the top surface and the bottom surface;
• a cutout disposed through the housing from the top surface to the bottom surface, the cutout at the bottom surface sized and shaped to accommodate a port of a dialyzer, and the cutout at the top surface sized and shaped to accommodate one or more of (i) an outer diameter of tubing of an extracorporeal circuit of a dialysis system, and (ii) an outer diameter of a first end of a connector configured to couple the tubing to the port of the dialyzer, wherein a second end of the connector is configured to releasably secure the connector to the port of the dialyzer;
• an interior void within the side portion between the top surface and the bottom surface of the housing, the interior void having a maximum diameter larger than a maximum width of the cutout, the interior void sized and shaped to accommodate winged portions disposed between the first and second ends of the connector;
• and
• a first engagement portion disposed on the bottom surface of the housing;
• and
• a second engagement portion on an end of the dialyzer that includes the port, wherein the second engagement portion is disposed on a cap of the dialyzer, adjacent to, but separated from, the port, and wherein the first engagement portion and the second engagement portion are couplable, and when so coupled, the winged portions of the connector are mitigated from rotating relative to the end of the dialyzer thereby securing the connector in a substantially fixed rotational position.
