摘要： A wafer is used in a device for the selective connecting and disconnecting of plastic tubes. The wafer is in the form of a heated plate having an outwardly extending scoop on each side thereof. The wafer also includes a generally straight line horizontal slit extending through the plate from the trailing downstream edge inwardly. In order to assure single use usage of the wafer, an aperture is provided through the wafer with the aperture being covered by a sensing material. A sensor in the device will inactivate the device if the sensing material is not detected.

摘要： A pair of hollow plastic tubes are welded together by mounting each tube in the clamp jaws of a holder in a bent condition to form the U-shape. A structural element is utilized to create a space between the bight of the U-shape and the holder. The bent tubes are disposed toward each other. A tube section separating member is moved into contact with the bent tubes and through the space between each bight and its holder to create a set of two tube sections from each bent tube. A tube section from one set is aligned with a tube section from the other set and the aligned sections are welded together. The structural element may be a weld seam resulting from a prior welding.

摘要： Two thermoplastic tubes are welded together in a process which includes severing the tubes by a severing wafer having a temperature of about 350.degree. F. to create two cut sections. The severing wafer is removed from the space between the tubes and a hot wafer having a temperature of 500.degree.-1200.degree. F. is inserted in the space to radiantly heat the tube ends so that they are welded when pressed-together while in an unflattened and open condition.

摘要： A plastic tube is sealed at its end by placing the tube in a pair of spaced apart tube holders having tube receiving pockets. The tube is cut by a cutting device movable into and out of the space between the pockets to form two distinct tube sections which are melted at their ends while in the clamped condition. The cut ends are then brought into contact with each other in a mis-aligned condition offset by one-half the thickness of a tube wall to seal the tube end.

摘要： Plastic tubes are welded by first placing the plastic tubes across aligned tube slots in a pair of side by side tube holders. The tubes are clamped to create a fluid free area. The clamps in one of the tube holders are shifted laterally away from the other tube holders to increase the fluid free area of each tube. A cold cutting device cuts through the clamped tubes to create four stub ends. The four stub ends are heated/melted. The stub ends are realigned so that the one stub end in one holder is aligned with the other stub end of the other tube holder and the realigned stub ends are pressed into contact with each other to create a weld seam.

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： Two thermoplastic tubes are welded together by pre-cutting the tubes to create two ends which are axially aligned when placed in a holding device. A wafer is inserted in the space between the cut ends and the wafer is heated to melt the cut ends while the cut ends are in a non-flattened condition. After the wafer is removed the melted cut ends are pressed against each other to weld the cut ends 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： Blood is purified by removing the whole blood from a patient and feeding the blood into a manifold in a centrifuge. A purifying chamber is formed in the centrifuge from a plurality of co-arcuately arranged modules. The blood is supplied from the manifold to each of the modules. Each module contains a stack of dialysate membranes. Fresh dialysate is fed into the manifold and then to each of the modules. Under centrifugal force the cells are separated from the plasma. The plasma is purified by removing contaminants as a result of the action of the dialysate and membranes. The purified blood is returned to the patient by being fed back to the manifold and then to the patient. The used dialysate/contaminants are fed from the modules back to the manifold and out of the centrifuge.

摘要： An ionomeric modified poly-ether-ester plastic material combined with a small amount of polyvinylchloride is used as a substitute for the conventional uses of polyvinylchloride 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.
