Abstract: An apparatus, a system and a method for venting a gas from a liquid delivery system are provided. A venting tube may be provided and may be positioned within a chamber that contains the liquid. The liquid may have a top surface within the chamber. The venting tube may have an opening covered by a liquiphobic membrane or a hydrophobic membrane. The membrane may define a plane or a surface which is not parallel to the top surface of the liquid. Gas may pass through a portion of the membrane into the venting tube. Moreover, the membrane may vent the gas. The membrane is non-parallel to the liquid, and, as a result, the membrane may be less prone to clogging.

Abstract: A membrane capable of sensing gaseous phase ammonia is provided. The membrane includes a hydrophobic membrane layer that has a microporous structure and a pH sensitive dye embedded within the microporous structure such that the membrane is capable of calorimetrically sensing a change in ammonia with a high degree of sensitivity and responsiveness as applied to, for example, a change in ammonia dissolved in a dialysis solution during dialysis therapy.

Abstract: A biosensor capable of monitoring a number of different constituents of a dialysate solution used during dialysis therapy is provided. The biosensor of the present invention includes an integrated array of reactive elements and sensing elements that can be hydraulically coupled to the dialysate solution. In this regard, the biosensor can be utilized to provide on-line monitoring of total solutes removed from a patient during dialysis therapy, infection levels and/or other desirable parameters such that an overall assessment of dialysis therapy can be readily evaluated.
