Abstract

A conduit connectible in a fluid transfer system to provide for the through flow of a fluid moving between a transfer device and internal patient includes a transmission line incorporated therewith having a distal end for signal communication with a signal generator and a proximal end connected to a terminal on a mating surface of a female connector and arranged thereon to establish a signal transmission path with a terminal on a mating surface of a second conduit, such as a port of the fluid transfer device, as the mating surfaces engage to establish fluid communication between the conduit and the port.

Claims

1. A conduit comprising:

a hollow, flexible tubular body having a first end and a second end;

an electrical transmission line disposed at said body and proceeding between said first end and said second end and having a first set of terminals disposed at said first end and a second set of terminals disposed at said second end; and

an interface permanently attached at said first end having an interior at which said first terminals are disposed, said interface being adapted for mating with a complementary interface to simultaneously provide an electrical connection to said first terminals and a fluid coupling to said hollow body.

2. A conduit as claimed in

claim 1

wherein said interface comprises a male connector having a mating surface at which said first set of terminals is disposed.

3. A conduit as claimed in

claim 1

wherein said interface comprises a female connector having a mating surface at which said first set of terminals is disposed.

4. A conduit comprising:

a hollow tubular body having a first end and a second end;

electrical conductors disposed at said hollow body and proceeding between said first end and said second end;

an interface disposed at said first end having a first set of terminals connected to said electrical conductor and adapted for mating with a complementary interface for producing an electrical connection to said electrical conductors and a fluid connection to an interior of said hollow body; and

a sensor connected to said electrical conductors and disposed at said second end for sensing a parameter relating to fluid flow in said hollow body.

5. A fluid transfer system comprising:

a fluid transfer device;

a conduit connectible in a flow path between said transfer device and a location adapted to provide fluid flow to a patient;

a sensor for monitoring a parameter of said fluid flow and for generating a signal representing said parameter;

a processing unit supplied with said signal which generates an output signal dependent thereon;

a transmission line incorporated with said conduit having a first end connected to said sensor and a second end for connection to said processing unit;

said fluid transfer device having a port for transferring fluid into and out of said fluid transfer device and having an externally accessible surface;

a terminal at said externally accessible surface connected to said processing unit; and

said conduit having an interface permanently attached thereto for mating with said port for simultaneously electrically connecting said transmission line to said terminal and for producing a fluid coupling of said conduit with said fluid transfer device.

6. A system as claimed in

claim 5

wherein said interface is a male connector having a mating surface at which said terminal is disposed, and wherein said port is a female connector having a mating surface complementary to said mating surface of said male connector.

7. A system as claimed in

claim 5

wherein said interface is a female connector having a mating surface at which said terminal is disposed, and wherein said port is a male connector having a mating surface complementary to said mating surface of said female connector.

8. A system as claimed in

claim 5

wherein said fluid transfer device receives said output signal from said processing unit and regulates transfer of said fluid into and out of said fluid device dependent on said output signal.

9. A system as claimed in

claim 5

further comprising a detector electrically connected to said terminal at said port for detecting connection of said sensor to said transmission line.
