    摘要： An ionomeric modified poly-ether-ester plastic material is used as a substitute for the conventional uses of polyvinyl chloride in such applications as tubing for medical applications, for bags and other medical containers, for tubing in food processing and as sheets and films for bacterial and virus exclusion. The ionomeric modified poly-ether-ester has various advantages which make it particularly suitable for such uses.

    摘要： A sterile containment welding device for plastic tubes comprises a pair of side by side spaced tube holders. Each of the tube holders includes a clamp base and a clamp lid. A pocket is provided in each clamp base extending completely across the clamp base so that a plastic tube could be inserted into the pocket and clamped in the holder when its clamp lid is moved to a closed position. Pockets of the side by side tube holders are alignable with each other to permit a plastic tube in one of the holders to be welded to the plastic tube in the other of the holders. A tube locating member is movably mounted at the end of each pocket in the space between the holders. The tube locating member has a wall disposed in the space beyond the pocket for positioning its plastic tube in the proper position for the later welding step when its tube is moved into contact with the walls. An inactivating member is mounted to each clamp lid to contact the tube locating member and move it out of contact with its plastic tube upon the closing of the lid so that the tubes are exposed to be heated and welded together.

    摘要： Thermoplastic tubes are welded together in a dry condition with the tubes being open and maintained in their undistorted condition during the welding step. In an alternative technique a branch tube is welded to a main tube by placing the tubes in a non-parallel orientation in a holding device. A wafer cuts completely through one tube to form two tube sections. The wafer also cuts a notch from the other tube. One of the tube sections is shifted to become aligned with the notched other tube and welded thereto. A further technique includes placing at least one tube in a holding device which has a false floor for pressing against an area of the tube while the tube is being flattened at two spaced locations on opposite sides of the area. When the false floor is moved away from the tube a partial vacuum results. An air pocket is formed when the tube is severed by a wafer by air flowing into the cut tube.

    摘要： A process, apparatus and system for making a sterile connection between two thermoplastic resin tubes is disclosed. The tubes are cut by a hot cutting means so as to form a molten interface between the tubes and the cutting means. The tubes are aligned with each other and slid off an edge of the cutting means while being urged together. As the thermoplastic resin cools a sterile weld is formed. The cutting means should either be thin or have a sharp edge where the aligned tubes are slid off and joined.
