摘要： A pumping cassette including a housing having at least two inlet fluid lines and at least two outlet fluid lines. At least one balancing pod within the housing and in fluid connection with the fluid paths. The balancing pod balances the flow of a first fluid and the flow of a second fluid such that the volume of the first fluid equals the volume of the second fluid. The balancing pod also includes a membrane that forms two balancing chambers. Also included in the cassette is at least two reciprocating pressure displacement membrane pumps. The pumps are within the housing and they pump the fluid from a fluid inlet to a fluid outlet line and pump the second fluid from a fluid inlet to a fluid outlet.

摘要： Methods, device, and systems for preparing peritoneal dialysis fluid and/or administering a peritoneal dialysis treatment are disclosed. In embodiments, peritoneal dialysis fluid is prepared at a point of use automatically using a daily sterile disposable fluid circuit and one or more long-term concentrate containers that are changed only after multiple days (e.g. weekly). The daily disposable may have concentrate containers that are initially empty and are filled from the long-term concentrate containers once per day at the beginning of a treatment.

摘要： A method of automatically ensuring against chloramine contamination in purified product water includes supplying input water to the system and purifying the water to generate the purified product water. The purifying includes removing chlorine and chloramine contamination from the water using a carbon filter and supplying chlorine-depleted water to a deionization filter, and deionizing the chlorine-depleted water using said deionization filter. The product water is supplied to a sensor for continuous monitoring of the resistivity of the purified product water by the first sensor, and an alarm is generated indicating possible chloramine breakthrough when the resistivity of the product water falls below a predetermined resistivity level, which is selected to provide a reserve filter capacity before breakthrough would occur. The carbon filter is replaced at least responsively to the alarm to ensure excess capacity of said carbon filter sufficient to prevent chloramine breakthrough in said product water.

摘要： An extremely lightweight and compact heating system greatly increasing patient mobility is provided. The use of a flat plate can be used to greatly decrease package size and weight while providing comparable heat transfer by exploiting the ability of the dialysis bags to conform to this surface and through the greater heating area possible with the flat plate design. A short rim around the plate provides centering and protecting against minor leakage without substantially increasing package height. Protection against leakage is buttressed by sealing the rim to the plate and the use of 12 V only within the heating unit. The result is a lightweight warming device with a short that can be easily transported by the patient greatly improving patient lifestyle and freedom.

摘要： A wearable automated peritoneal dialysis (“APD”) machine is disclosed herein. In an example, the APD machine includes a delivery system connected to a dialysis fluid container and a catheter connected to a peritoneal cavity of a patient. The delivery system includes a pump for pumping fresh dialysis fluid from the dialysis fluid container to the patient, and pumping used dialysis fluid from the patient to the dialysis fluid container. The delivery system also includes a control unit configured to control the pump using a flow rate measured by a flow sensor and a pressure measured by a pressure sensor. The APD machine also includes a clothing item to be worn by the patient. The clothing item includes a first section to retain the dialysis fluid container, a heating element positioned adjacent to the first section for warming the fresh dialysis fluid, and a second section to retain the delivery system.

摘要： A treatment device system includes a treatment machine for performing a therapy on a patient, the treatment machine including at least one fluid conveyor and a controller, the controller having a first memory, to cause the at least one fluid conveyor to produce a therapeutic fluid by mixing purified water and at least one concentrate. The system also includes and a water purifier in fluid communication with and providing the purified water to the treatment machine. A wired or wireless control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier, wherein the controller of the treatment machine transmits data via the control line to the internal central controller of the water purifier for control of the water purifier, the data provided based on at least one of the operator inputs received via the user interface.

摘要： Systems and methods include a heat transfer body with opposing major surfaces formed from a thermally conductive substrate in intimate thermal interaction with an alumina exterior surface that extends across the major surfaces of the body. In an illustrative example, the heat source may be a substantially planar, silicone-based heater source (P-SBHS). The heat transfer body may be configured to thermally interact, for example, heat from a heat source proximate a first of the major surfaces to a second of the major surfaces. A temperature sensor module may be located, for example, proximate to the first major surface such that a temperature sensor thermally interacts with the first major surface. The temperature sensor module may, for example, insulate the temperature sensor from the P-SBHS.

摘要： This disclosure relates to a method for determining a fluid balance between a first volume flow in a first section of a fluid circuit and a second volume flow of a second section of the fluid circuit. The method may also include adjusting, assuming or detecting a first temperature in the first section of the fluid circuit and a second temperature in the second section of the fluid circuit, or detecting a temperature difference between the first and the second sections. The method may also include detecting a second volume flow in a second section of the fluid circuit and forming a balance from at least the first volume flow and a corrected value of the second volume flow. The corrected value is determined from the detected second volume flow and the second temperature and/or the temperature difference.
