20100222735 | PORTABLE APPARATUS FOR PERITONEAL DIALYSIS THERAPY - A portable peritoneal dialysis apparatus having (1) a hinged door for enclosing a disposable cassette that seals tightly shut using air pressure; (2) accurate pressure sensing of pressures applied to the patient through an enclosure in the disposable cassette; (3) two pumps that can operate separately or in tandem actuated by two separate stepper motors; and (4) a touch screen user interface where indicia of the operating mode is always visible along with indicia for the other possible operating modes and the mode can be changed by touching one of these indicia. | 09-02-2010 |
20100319780 | Method For Actuating Valves For Controlling a Flow Path and Machines, Especially Medical Treatment Machines - The present invention includes a method for the control of valves for flow path control, in particular in a medical treatment machine, having a plurality of processes for the manufacture of flow paths by control of a group of valves, with each process claiming a group of valves suitable for its carrying out for itself so that other processes cannot change the switching state of these valves and with each process itself making a decision on the release of the valves claimed by it. The invention furthermore includes a method for the monitoring of the then current and/or scheduled state of a plurality of valves in the flow path control, in particular in a medical treatment machine, having the steps: determining the then current and/or scheduled switching state of the valves; determining the connections resulting from the switching state of the valves; comparing the resulting connections with a predetermined number of non-permitted connections. The invention furthermore includes machines, in particular medical treatment machines, having corresponding valve or valve actuator controls. | 12-23-2010 |
20100331768 | METHOD FOR CHECKING AND/OR MONITORING THE TIGHTNESS OF A PLURALITY OF PNEUMATICALLY OR HYDRAULICALLY ACTUATED ACTUATORS, AND MACHINE, ESPECIALLY MEDICAL TREATMENT MACHINE - The present invention relates to a method for checking and/or monitoring the leak tightness of a plurality of pneumatically or hydraulically actuated actuators of a machine, in particular a plurality of valve actuators of a medical treatment machine, wherein pressure is exerted on the actuators in different combinations during the operation of the machine, wherein the common pressure drop occurring during a stationary operating phase at the actuators on which pressure is exerted in the respective combination is measured for a plurality of different combinations of actuators on which pressure is exerted, and wherein a respective leak tightness value is determined for individual actuators and/or groups of actuators with the pressure drop which is measured for those combinations and in which the respective actuator and/or the respective group of actuators on which pressure is exerted being taken into said leak tightness value. The invention furthermore includes a machine, in particular a medical treatment machine, having a corresponding valve actuator monitoring. | 12-30-2010 |
20110000902 | METHOD AND DEVICE FOR HEATING SOLUTIONS, PREFERABLY DIALYSIS SOLUTIONS - The invention relates to a method and an apparatus for the heating of solutions, preferably dialysis solutions, to a wanted desired temperature, wherein a solution presented in a bag is heated on a heater system including a heater by means of a two-step control. In accordance with the present invention, the temperature forming the lower switch-on threshold of the heater and the temperature forming the upper switch-off threshold of the heater vary. | 01-06-2011 |
20110196289 | CASSETTE SYSTEM FOR PERITONEAL DIALYSIS MACHINE - A peritoneal dialysis (PD) system that includes a disposable PD cassette including a base having a substantially planar portion and a dome-shaped protrusion extending from the substantially planar portion and a flexible membrane attached to the base and covering a recessed region of the dome-shaped protrusion to form a pumping chamber between the flexible membrane and the recessed region of the dome-shaped protrusion. The system also includes a PD machine including a deck and a door hinged from one side to the deck. The door and the deck can cooperate to form a cassette compartment, and the door has a cylindrical recess positioned to receive the dome-shaped protrusion of the base of the disposable PD cassette when the disposable PD cassette is disposed in the cassette compartment and the door is closed. | 08-11-2011 |
20130310736 | DIALYSIS CASSETTES AND RELATED SYSTEMS AND METHODS - A method that includes conveying overheated dialysate through a cassette in a manner to reduce the temperature of the overheated dialysate, and a dialysis system including a control unit configured to cause overheated dialysate to be conveyed through a cassette in a manner to reduce the temperature of the overheated dialysate. | 11-21-2013 |
20140180200 | MEDICAL DEVICE HEATERS AND METHODS - A medical device having a heater with at least one heating element which has mains voltage applied to it by a heating control unit. The heating control unit includes a monitoring arrangement and a switching arrangement. The monitoring arrangement can recognize the zero crossings of the mains voltage, and the switching arrangement can switch the at least one heating element on or off in the zero crossing. The heating control unit controls the power of the heating by switching on and off of one or more half cycles of the mains AC voltage. | 06-26-2014 |
