Abstract

A fluid collection system includes an input unit having a hollow needle coupled through a section of flexible conduit to an anticoagulant reservoir which is in turn coupled via a second section of hollow conduit to a first sterile connector. A collection container, which can be a dry, flexible, plastic bag, is coupled by a plastic conduit to second and third sterile connectors. The first and second connectors can be joined together and sealed to form a sterile system. A transfer container includes a flexible plastic container coupled via a hollow plastic conduit to a fourth sterile connector. The fourth sterile connector is joinable with the third sterile connector to form a sterile two container system. Fluids collected in the primary container can then be transferred to the secondary container.

Claims

1. A modular, sealed fluid transfer system assemblable into a selected configuration in response to applied radiant energy comprising:

a first flexible container module with integrally attached first and second tubing members, each said tubing member having a free end, first and second shaped, non-piercing plastic connector means, each said connector means coupled to a respective one of said first and said second free ends;

a filter module with a tubular conduit having first and second ends, a piercing needle in fluid flow communication with said first end, a fluid filter element carried by said conduit and a third, shaped, non-piercing plastic connector means coupled to said second end;

a vial module including a fluid containing vial and a fluid flow conduit with first and second ends, said vial coupled to said first end of said conduit, said second end carrying fourth shaped, non-piercing plastic connector means;

said first and said third connector means slidably engageable with one another so as to form a permanent, sealed fluid flow path between said connector means in response to applied radiant energy and

said second and said fourth connector means slidably engageable with one another so as to form a permanent, sealed fluid flow path between said connector means in response to applied radiant energy.

2. A modular sealed fluid transfer system as in claim 1 with each said connector means including a planar connection region such that as respective connector members engage one another, respective of said planar connection regions are juxtaposed with one another.

3. A modular sealed fluid transfer system as in claim 1 with each said connector means substantially identical to each other of said connector means.

4. A modular, sealed fluid transfer system assemblable into a selected configuration in response to applied radiant energy comprising:

a first flexible container module with integrally attached first and second tubing members, each said tubing member having a free end, first and second shaped, non-piercing plastic connector means, each said connector means coupled to a respective one of said first and said second free ends;

a fluid inflow module selected from a class including

(a) a filter module with a tubular conduit having first and second ends, a piercing needle in fluid flow communication with said first end, a fluid filter element carried by said conduit and a third, shaped, non-piercing plastic connector means coupled to said second end; and

(b) an anticoagulant containing module with tubular conduit flow means having first and second ends, a piercing needle in fluid flow communication with said first end, an anticoagulanat container carried by said conduit flow means, and shaped non-piercing plastic connector means coupled to said second end;

a fluid outflow module selected from a class including

(c) a vial module including a fluid containing vial and a fluid flow conduit with first and second ends, said vial coupled to said first end of said conduit, said second end carrying fourth shaped, non-piercing plastic connector means;

(d) multibranch transfer conduit flow means having an initial conduit member with first and second ends, as well as secondary and tertiary conduit members each with first and second ends, said initial conduit member coupled to said secondary and tertiary conduit members at respective of said second ends, shaped non-piercing plastic connector means coupled to each said first end; and

(e) a fluid receiving container module carrying non-piercing plastic connector means;

said first connector means slidably engageable with connector means associated with said fluid inflow module so as to form a sealed fluid flow path between said connector means in response to applied radiant energy; and

said second connector means slidably engageable with connector means associated with said fluid outflow module so as to form a sealed fluid flow path between said connector means in response to applied radiant energy.

5. A modular sealed fluid transfer system as in claim 4 with each said connector means including a planar connection region such that as respective connector members engage one another, respective of said planar connection regions are juxtaposed with one another.
