Abstract: A continuous pH monitoring system and method of using it, includes a catheter assembly having a flexible compressible multipassagewayed tube, an anchor assembly connected to the tube to secure it within the nasal cavity, an indicator assembly having a sensor device within the tube to monitor the pH in the stomach, a vent within the tube to equalize pressure inside the stomach with the ambient pressure, and an aspirating assembly attached to the tube for removing stomach fluid.

Abstract: An exercise kit, and a method of using it, which includes an exercise apparatus having a compact curved base member, which generally conforms to the shape of the back of a user, and a set of transverse rollers which are adapted to enable the base member to roll upwardly and downwardly over a wall or other such surface. A device enables the base member to be worn on the lower back of the user, who can press the rollers against a wall as the user performs various excercises, for enabling the leg muscles to be exercised in a comfortable, easy manner. The base member is also curved transversely to distribute pressure uniformly over a large area of the back to help reduce discomfort to the wearer. A pair of spaced apart transverse rollers for distributing pressure across a large area of a wall uniformly, each include an extruded thermoplastic member to help make the apparatus relatively inexpensive to manufacture, and light in weight.

A device enables the base member to be worn on the lower back of the user, who can press the rollers against a wall as the user performs knee bends repeatedly, for enabling the leg muscles to be exercised in a comfortable, easy manner.
