Abstract: A fluid sampling device has an elongate tube formed substantially of polyphenylene sulfide. A top end fitting is formed to the top end of the tube and is configured for connection to a tether. A bottom end fitting is similarly formed to the bottom end of the tube and has a check valve formed therein for allowing fluid to flow therethrough into the tube when the fluid sampling device is lowered into a fluid and for inhibiting fluid flow therethrough out of the tube when the tube is being raised and handled. The tube, top end fitting, bottom end fitting, and check valve are all formed of an inert material so as to maintain the integrity of the fluid sample collected. The use of polyphenylene sulfide provides a lightweight fluid sampling device which is durable enough to resist damage during routine handling and use.

Abstract: An improved toilet training device and method of utilizing the same is disclosed characterized by use of a thin paper stock element adapted to float in a planar configuration upon the water surface within the toilet bowl for prolonged duration and upon contact with urine, rapidly sink within the toilet bowl and become flushable through the toilet bowl waste drain system. The element is preferably provided with indicia printed on both sides thereof representing a target or other geometric shape normally familiar to children and thereby attract the attention of a child and encourage toilet training.
