20110168291 | DEVICE FOR FILLING A FILTER, AND METHOD THEREFOR - The present invention relates to an apparatus and a method for the filling of a medical filter, wherein the filter has at least one first space and one second space which are semipermeably separated by one or more membranes, wherein the spaces each have at least one inflow and outflow, and wherein a detection unit having first and second means is provided, with liquid discharge from at least one of the spaces being able to be detected by means of the first means and the state of the filling of the filter being able to be determined by means of the second means with reference to the detected liquid discharge. | 07-14-2011 |
20110237997 | METHOD AND DEVICE FOR MONITORING THE INTRODUCTION OF SUBSTITUTION FLUIDS UPSTREAM OF DOWNSTREAM OF A DIALYZER OF FILTER - A method is provided for monitoring the introduction of substitution fluids for an extra-corporeal blood processing device with an extra-corporeal blood circuit, comprising an arterial blood line, running from an arterial patient connection to a first chamber of a dialyzer or filter divided into said first chamber and a second chamber by a membrane and a venous blood line, running from the first chamber of the dialyzer or filter to a venous patient connection. A device is provided for monitoring the introduction of substitution fluids for an extra-corporeal blood processing unit with an extra-corporeal blood circuit and an extra-corporeal blood processing device with a device for monitoring the introduction of substitution fluids. The method and the device for monitoring the introduction of substitution fluids are based on monitoring the fluid level in the bubble trap, arranged in the venous blood line of the extra-corporeal blood circuit. The method and the device require that fluid is added to fill the extra-corporeal blood circuit, for example, for a rinsing procedure of the extra-corporeal blood circuit by means of the substitution fluid supply line arranged upstream or downstream of the dialyzer. A pre-dilution can be commanded when, after initiating the rinsing process the fill level in the bubble trap does not drop below a certain level. When by contrast the fill level drops below a given level a post-dilution can be commanded. | 09-29-2011 |
20120061310 | Dialysis Fluid Cassettes and Related Systems and Methods - A dialysis fluid cassette that includes a base and a flexible membrane attached to the base. The flexible membrane and the base cooperate to at least partially define a venting chamber and a fluid channel fluidly connected to the venting chamber. | 03-15-2012 |
20120156097 | Medical Fluid Cassettes and Related Systems - The invention relates to an apparatus for the treatment of a medical liquid comprising a liquid treatment machine and a cassette insertable therein substantially made of a rigid base body of the cassette with fitted chambers and passages and a foil covering them. | 06-21-2012 |
20120181231 | Dialysis Systems and Related Methods - A dialysis machine that includes a valve body defining a pressure passage and a sealing cap disposed at a first end of the valve body such that the sealing cap closes off the pressure passage at the first end of the valve body. The sealing cap has a deformable area configured to deform outwardly away from the valve body when pressurized fluid is introduced into the pressure passage of the valve body. The sealing cap is configured so that, when a dialysis fluid cassette is disposed in a cassette compartment of the dialysis machine and pressurized fluid is introduced into the pressure passage of the valve body, the deformable area obstructs a fluid channel of the dialysis fluid cassette to control dialysis fluid flow therethrough. | 07-19-2012 |
20120181331 | METHOD FOR QUERYING A SPECIFICATION FEATURE OF A MEDICAL TECHNICAL FUNCTIONAL MEANS, A MEDICAL TECHNICAL FUNCTIONAL MEANS, A MEDICAL DEVICE AND A CONTROL UNIT - The present invention relates to a method for querying a specification feature arranged in, at or on a medical technical functional means, the method comprising the step of: querying the specification feature by means of a medical device functionally coupled to or to be coupled to the medical technical functional means or by means of a device or means connected to or being arranged in signal transmission with the medical technical treatment apparatus. The invention further relates to a medical technical functional means, a medical device and a control unit. Furthermore, the present invention relates to a digital storage medium, a computer program product and a computer program. | 07-19-2012 |
20120193290 | Method and device for controlling an extracorporeal blood treatment apparatus - A method and device for controlling an extracorporeal blood treatment apparatus, which can be operated as a hemodialysis apparatus, hemofiltration apparatus or hemodiafiltration apparatus, are disclosed. The method and device make provision, apart from balancing the fluids as a function of the weights of the containers, for the measurement of the weight reduction or increase of at least one of the containers in the time interval in which the pump assigned to the respective container performs a preset number of revolutions or pump strokes. The change in the weight of the container for a half or one pump revolution can be determined. The delivery rate of the respective pump is ascertained from the measured weight reduction or increase in the specific time interval, thereby permitting the precise determination of the actual delivery rate of one or more pumps. The actual delivery rates of all the pumps are preferably monitored. | 08-02-2012 |
