Certain embodiments described herein are directed to methods for treating loss of protective sensation. In certain embodiments, loss of protective sensation may be restored by application of an effective amount of a pulsed current at, for example, an effective pulse frequency. Devices and systems designed to treat loss of protective sensation are also described.

Methods and devices for treating neuropathy and loss of protective sensation

A proportioning process and apparatus is provided for forming a liquid composition by admixture of a plurality of liquid components. The apparatus includes a main chamber, a subchamber positioned within the main chamber and conduits for introducing the liquid components sequentially into the subchamber which then overflow into the main chamber. The main chamber and subchamber are provided with outlets so that the liquid therein can be admixed to form the liquid composition. A pressure sensor in the subchamber is provided to measure the head pressure of each component in the subchamber and the main chamber which, because the dimensions of the subchamber and main chamber are known, can be used to measure the volumes of the liquid components to be admixed. A level sensor is provided at the top of the main chamber to be used as a calibration point and for overflow detection.

A process is provided for purifying potable water to produce American Association for Advancement of Medical Instrumentation (AAMI) standard water for dialysis, United States Pharmacopeia Convention, Inc. USP XXII specifications water for injection or sterile water for injection. Potable water is passed through a plurality of treatment steps including a preliminary filtration step, a carbon adsorption module and a reverse osmosis module to produce water to the quality specified by AAMI for hemodialysis. An ion exchange filtration step is added to the steps stated above to produce USP XXII quality specifications for water for injection and a disposable sterilizing microfilter is further added to all the steps stated above to produce sterile water for injection. The process is designed such that the system is sanitized with hot water and subsequently flushed at a temperature and time that will control microbial population as specified by the user requirements without degrading the materials of construction in the treatment steps, for example at 80.degree. C. for one hour. The sterile microfilter used for the production of sterile water is a disposable device changed periodically to maintain sterility of the final solution.
