Abstract: A dialysis procedure catheter for accurately facilitating insertion of a needle into a dialysis patient's body. The dialysis procedure catheter includes a tubular member having a bore being disposed therethrough, and also having an enlarged main portion and a branch portion, and further having a needle; and also includes a plug assembly including a plug member being removably disposed in the bore of the needle; and further includes a handle being attached to the enlarged main portion of the tubular member; and also includes a hose having a first end being attached to the branch portion; and further includes a hose clamp for crimping the hose; and also includes a hose connector being attached to a second end of the hose for connecting to a dialysis machine.

Abstract: An inflatable pneumatic plug useful for expediting the hydrostatic testing of bathtub and water plumbing installations. The pneumatic plug has a semi-rigid handle tube with an air valve at one end and an inflatable tube attached to its opposite end. The inflatable tube and the handle are of sufficiently small diameter to pass through the overflow drain in the bathtub, past the drain stopper assembly and into the drain trap without disassembly of the plumbing. The inflatable tube, such as a latex tube, is chosen with a length and wall thickness such that the inflatable tube is relatively stiff and will tend to deflect laterally around a solid obstacle when advanced into the plumbing rather than flattening axially. The inflatable tube is inflatable to a diameter at least five times greater than its deflated diameter for making a water-tight seal in a plumbing conduit.

Abstract: A water ski aid for supporting a water skier includes an inflatable seat member. A pair of inflatable arms is used to secure the skier to the inflatable seat member. The free ends of the arms overlap the body of the skier when in a secure position in the seat member. The arms separate when the skier gains sufficient speed to overcome the drag of the inflatable seat member.
