摘要： An extruded, preferably flexible mixing tube having unitary construction and a lumen coextensive with the length thereof. A mixing portion of the lumen is tortuous and operable for mixing two or more comingled fluids flowing therethrough. The lumen of the mixing tube preferably includes a smooth cylindrical connector portion at both ends thereof dimensioned to receive tubing connectors. The mixing portion of the lumen is disposed between the connector portions and is in fluid communication with the connector portions of the lumens at both ends of the mixing tube. The mixing tube may be extruded in any desired length. The tortuous mixing portion of the lumen may have any desired cross-sectional geometry. In one embodiment the mixing portion is defined by a spiral conduit. In another embodiment, the mixing portion of the lumen varies in internal diameter periodically along the length of the mixing tube. In yet another embodiment, the mixing portion is comprised of a linear sequence of two or more tortuous conduits having different cross-sectional geometries.

摘要： A tubing having unitary construction and having a single lumen portion, a multilumen portion and a transition portion therebetween. The single lumen is in fluid communication with each and every lumen comprising the multilumen portion. The tubing may be made in any desired length by means of extrusion. The outer surface of the tubing may be either smooth or grooved and have any desired cross-sectional geometry. Similarly, any of the lumens can be made to have a desired cross-sectional shape and size. Although the tubing can be made from any extrudable material, a preferred material is medical grade silicone clastomer. An extrusion apparatus and a method for making the tubing in a continuous process is described.

摘要： An extruded "Y" or bifurcated tube having unitary construction and an extrusion apparatus therefor. The "Y" tube includes three separate tubes, each tube having a central lumen, and a transition portion integral with the tubes and providing physical connection and fluid communication between the individual lumens of the three separate tubes. The first of the three tubes has a first lumen and is first formed by extrusion through a convention extruding die. The extruder die then gradually bifurcates the first tube, providing a gradual transition between the first tube and the second and third tubes. The lumens in the second and third tubes thus formed remain in uninterrupted fluid communication with the lumen of the first tube. The bifurcation takes place with the first tube to form second and third tubes smoothly and over a transition distance which is easily controlled by the extruder die. The bifurcated second and third tubes are continuous with the first tube making the "Y" tube unitary. There are no joints to pull apart or "T" or "Y" connectors between the tubes which may be vulnerable to separation. Moreover, since the extruded bifurcated or "Y" tubing is unitary and the first, second and third tubes may have any desired length without limitation, the extruded bifurcated tubing of the present invention overcomes length limitation on analogous first, second and third tubes imposed by practical engineering considerations operable for molding "Y" tubing.
