Drug delivery system and method

A fluid delivery set comprising:

• a conduit defining a fluid flow path, said conduit having a first end portion and a second end portion;
• a first connector mounted on said first end portion of said conduit, said first connector being fluidly connectable to a source of fluid, said first connector defining a fluid flow path therethrough, said fluid flow path defined by said first connector being in fluid communication with said fluid flow path defined by said conduit;
• and
• a second connector having a first end portion and a second end portion, said first end portion of said second connector mounted on said second end portion of said conduit, said second connector defining a fluid flow path therethrough, said fluid flow path defined by said second connector being in fluid communication with said fluid flow path defined by said conduit, a pierceable seal disposed in and fluidly sealing said fluid flow path defined by said second connector, said second connector further including a piercing member having a piercing tip mounted on a proximal end portion of said piercing member, said piercing member movably disposed in said fluid flow path defined by said second connector, said piercing member defining a fluid flow path therethrough, said piercing member being movable between a first position and a second position, said piercing member having a distal end portion constructed to be engageable in substantial end-to-end abutment by a male luer member inserted into said second connector at said second end portion of said second connector, said piercing member being movable between said first and second positions by a male luer member inserted into said second connector at said second end portion of said second connector, said piercing tip being disposed on a first side of said pierceable seal when said piercing tip is in said first position, said pierceable seal being pierceable by said piercing tip as said piercing member is moved by a male luer member from said first position to said second position, said piercing tip being disposed on a second side of said pierceable seal when said piercing member is in said second position, said piercing member establishing fluid communication through said pierceable seal when said pierceable seal is in said second position.

A method for delivering fluid from a primary container to a patient, said method comprising the steps of:

• providing an access tube set, said access tube set comprising:
• a conduit defining a fluid flow path, said conduit having a first end portion and a second end portion;
• a first connector mounted on said first end portion of said conduit, said first connector being fluidly connectable to a source of fluid, said first connector defining a fluid flow path therethrough, said fluid flow path defined by said first connector in fluid communication with said fluid flow path defined by said conduit;
• and
• a second connector having a first end portion and a second end portion, said first end portion of said second connector mounted on said second end portion of said conduit, said second connector defining a fluid flow path therethrough, said fluid flow path defined by said second connector being in fluid communication with said fluid flow path defined by said conduit, a pierceable seal disposed in and fluidly sealing said fluid flow path defined by said second connector, said second connector further including a piercing member having a piercing tip, said piercing member disposed in said fluid flow path defined by said second connector, said piercing member defining a fluid flow path therethrough, said piercing tip being disposed on a first side of said pierceable seal when said pierceable seal is in a first position, said pierceable seal being movable from said first position to a second position by a male luer member inserted into said second end of said second connector, said pierceable seal being pierceable by said piercing tip as said pierceable seal is moved from said first position to said second position, said piercing tip being disposed on a second side of said pierceable seal when said pierceable seal is in said second position, said piercing member providing fluid communication through said pierceable seal when said pierceable seal is in said second position;
• inserting a male luer member into said second end portion of said second connector;
• drawing a volume of fluid into said male luer member from said access tube set;
• disconnecting said male luer member from said second connector;
• and
• delivering said volume of fluid from said male luer member to a patient.

A method for delivering fluid from a primary container to a patient, said method comprising the steps of:

• a conduit defining a fluid flow path, said conduit having a first end portion and a second end portion;
• a first connector mounted on said first end portion of said conduit, said first connector being fluidly connectable to a source of fluid, said first connector defining a fluid flow path therethrough, said fluid flow path defined by said first connector being in fluid communication with said fluid flow path defined by said conduit;
• and
• a second connector having a first end portion and a second end portion, said first end portion of said second connector mounted on said second end portion of said conduit, said second connector defining a fluid flow path therethrough, said fluid flow path defined by said second connector being in fluid communication with said fluid flow path defined by said conduit, a pierceable seal disposed in and fluidly sealing said fluid flow path defined by said second connector, said second connector further including a piercing member having a piercing tip mounted on a proximal end portion of said piercing member, said piercing member defining a fluid flow path therethrough, said piercing member movably disposed in said fluid flow path defined by said second connector, said piercing member being movable between a first position and a second position, said piercing member having a distal end portion constructed to be engageable in substantial end-to-end abutment by a male luer member inserted into said second connector at said second end portion of said second connector, said piercing member being movable between said first and second positions by a male luer member inserted into said second connector at said second end portion of said second connector, said piercing tip being disposed on a first side of said pierceable seal when said piercing tip is in said first position, said pierceable seal being pierceable by said piercing tip as said piercing member is moved by a male luer member from said first position to said second position, said piercing tip being disposed on a second side of said pierceable seal when said piercing member is in said second position, said piercing member establishing fluid communication through said pierceable seal
• when said pierceable seal is in said second position;
• inserting a male luer member into said second end portion of said second connector;
• drawing a volume of fluid into said male luer member from said access tube set;
• disconnecting said male luer member from said second connector;
• and
• delivering said volume of fluid from said male luer member to a patient.
