A device for welding plastic tubes includes a pair of tube holders each of which has a tube clamp which includes an upper jaw and a lower jaw. The jaws in both of the tube clamps of both tube holders have smooth tube contacting walls to permit the tubing to slip through either side when the tube holders and tubes are being moved from a loading station to a stripping station to increase the length of fluid free area in the clamped tubes. A cutting/welding station provides for cutting the tubes and welding them together.

A device for welding plastic tubes includes a laterally movable tube holder having tube holding areas and a laterally fixed tube holder having tube holding areas. Each tube holder includes clamping structure for clamping each tube placed in the respective tube holder areas and for creating a fluid free area. A spring mechanism urges the laterally movable tube holder toward the laterally fixed tube holder to maintain the clamp faces flush against each other. A clamp locking mechanism is provided to supplement the action of the spring mechanism by maintaining the clamp faces flush against each other during the loading of the tubes.

An infection control device includes a plurality of air inlets spaced around the device's peripheral skirt. A negative ion ozone generator having a plurality of spaced pointed projections is inwardly of the peripheral skirt with a ground disk inwardly of the generator. Air flows through the inlets to the generator, to the disk and to a catheter exit site.

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.

A female urinary system includes an appliance which has a hollow urinary receiving open top body. The upper edge of the body is shaped to fit under the urethra. The body has an outlet passage for discharging urine flowing into the body from the urethra. A vaginal area locating bulb is mounted posteriorly of the body. The locating bulb has an arcuate outer surface having a contact portion which fits against the labia minora at the vestibule outwardly of the vagina. At least one longitudinal groove is provided on the posterior portion of the outer surface of the bulb from a location above the contact portion to the base of the bulb. A vent extends through the appliance from the hollow body below the upper edge to the base of the locating bulb.

A wafer for use in selectively connecting and disconnecting plastic tubes is in the form of a heatable plate having side walls and having a leading end and a trailing end. An outwardly extending scoop is formed on each of the side walls between and spaced from the leading end and the trailing end. A pair of slits is formed in the trailing end in line with the scoops for reducing the amount of plastic material remaining on the wafer.

Surgical/medical tubing and containers are made from an ionomeric modified poly-ether-ester plastic material is used as a substitute for the conventional uses of polyvinyl chloride. The ionomeric modified poly-ether-ester has various advantages which make it particularly suitable for such uses, as well as other uses such as other medical containers, for tubing in food processing and as sheets and films for bacterial and virus exclusion.
