A system and method for determining a concentration of total chlorine in dialysis water are provided. The system comprises a main unit housing an iodide/water sample chamber and a reducing agent chamber. An electrode pair bridges the two chambers and generates tri-iodide proportional to the amount of total chlorine in the dialysis water. The electrode pair detects the amount of tri-iodide generated in proportion to the amount of active chloride in the dialysis water. The system is suitable for use in connection with, or for incorporation into, a water purification system for generating dialysis fluid, and may include a display that alerts the user to stop or prevent a hemodialysis treatment if the total chlorine level exceeds a predetermined level.

Integrated water testing system and method for ultra-low total chlorine detection

A system and method for determining a concentration of total chlorine in dialysis water are provided. The system comprises a main unit housing a KI/water sample chamber and a sodium sulfate chamber. A first electrode pair bridges the two chambers and generates tri-iodide proportional to the amount of total chlorine in the water sample. A second electrode pair in contact with fluid in the KI/water sample detects an amount of tri-iodide generated by the first electrode pair. The system is suitable for use in connection with, or for incorporation into, a water purification system for generating dialysis fluid, and may include a display that alerts the user to stop or prevent a hemodialysis treatment if the total chlorine level exceeds a predetermined level.

Total chlorine water detection system and method for medical fluid treatments

A medical fluid machine, such as a dialysis machine, includes a pump that pumps a medical fluid and sterile water or other disinfecting liquid, such as ozonated water, for flushing and reconditioning the medical fluid machine. The machine may also include a heater that heats the medical fluid or disinfecting solution in order to kill bacteria and other microorganisms that may contaminate the machine after use. Disinfecting the machine, and a disposable kit used with the machine, may allow re-use of the disposable within a reasonable amount of time after completion of the disinfecting procedure. Dialysate treated with ultra-violet light or water with low concentrations of ozone also helps make the disposable kits suitable for reuse.

Extended use dialysis system

The present invention provides a multiple layered non-PVC containing tubing structure. The tubing structure has a first and a second layer. The first layer is of a polymer blend of (a) from about 30% to about 50% by weight of the first layer a first polyolefin selected from the group consisting of a first propylene containing polymer, (b) from about 0 to about 50% by weight of the first layer a second polyolefin of an &#x3b1;-olefin containing polymer; (c) from about 0% to about 40% by weight of the first layer a radio frequency susceptible polymer and (d) from about 5% to about 40% of a first thermoplastic elastomer. The second layer is attached to the first layer and includes a non-PVC containing material.

A needless connector is provided which utilizes a resealable preslit septum valve. The valve is resiliently restrained relative to a housing with the valve and housing configured to accept a standard male luer lock having a luer tip which penetrates the valve through the opening to extend within the housing and a luer locking flange of the luer lock extending about the housing. The valve includes a disk shaped upper portion covering the opening, a lower portion spaced from the housing and extending downward from the disk shaped portion into a passageway defined by the housing, and an annular skirt to attach the septum to the housing. The connector exhibits satisfactory leak pressure after multiple connections and disconnects to the luer lock fitting and long periods of indwell of the luer tip.

Needleless connector

A protein-compatible polymer blend made from a water-soluble polymer and a matrix polymer. The glass transition temperature of either the water-soluble polymer or the matrix polymer is greater than the application temperature, i.e., the temperature at which the protein-compatible polymer blend is being used.
