Fluid Line Connector Devices Methods and Systems

Abstract

A frangible connector has a first side that forms a female luer when a second side is fractured at a predefined break line. The second side may be connected to a fluid circuit, for example, a source of medical treatment fluid such as dialysate.

1 . A connector device, comprising:
 an inline fluid channel element having first and second end portions adapted for bonding to tubing segments;   the inline fluid channel element having a middle portion defining a connector attached to the second end portion through a frangible portion that, when fractured, renders the connector operable to connect with a predefined mating connector;   the inline fluid channel having a positive and/or neutral draft from a first end thereof through and beyond the frangible portion such that the middle portion defining a connector has a tapering opening when the frangible portion is fractured.   
     
     
         2 . The device of  claim 1 , wherein the inline fluid channel element is shaped such that the connector that results from fracturing the frangible portion is of a female locking luer type. 
     
     
         3 . The device of  claim 1 , wherein the inline fluid channel element is shaped such that the connector that results from fracturing the frangible portion has thread portions. 
     
     
         4 . The device of  claim 1 , wherein the inline fluid channel element is shaped such that the connector that results from fracturing the frangible portion has an opening shaped to receive the predefined mating connector, a mouth of the opening coinciding with a circular channel defining the frangible portion. 
     
     
         5 . The device of  claim 1 , wherein the inline fluid channel is generally cylindrical in shape. 
     
     
         6 . The device of  claim 1 , further comprising a fluid circuit for a renal replacement therapy device permanently bonded to the first end portion. 
     
     
         7 . The device of  claim 1 , further comprising a releasably capped connector connected to the second end portion. 
     
     
         8 . The device of  claim 7 , wherein the releasably capped connector is of a locking luer type. 
     
     
         9 . The device of  claim 7 , wherein the second end portion is connected to a tubing segment and with a pre-installed non-reopenable clamp. 
     
     
         10 . The device of  claim 9 , further comprising a fluid circuit for a renal replacement therapy device permanently bonded to the first end portion. 
     
     
         11 . The device of  claim 9 , further comprising a releasably capped connector connected to the second end portion. 
     
     
         12 . The device of  claim 11 , wherein the releasably capped connector is of a locking luer type.
