摘要： An apparatus for determining at least one of the peritoneal pressure in the abdomen of a patient, and the drainage state of the abdomen of a patient, includes at least one pump for conveying a dialysis solution into the abdomen, and at least one measurement device for measuring the pressure in the dialysis solution. The apparatus has at least one control unit configured to control the pump and the measurement device such that a first measurement of the pressure is carried out by the measurement device with a stationary pump to obtain a first measured pressure value. The pump subsequently operates to convey a partial volume of the total inflow volume of the dialysis solution into the abdomen. The pump then stops, and a second measurement of the pressure is carried out by the measurement device to obtain a second measured pressure value.

摘要： The invention relates to the balancing of fluid streams in a dialysis system. In particular the invention relates to a cassette for conveying a first and a second fluid stream in a dialysis system, wherein the first and the second fluid streams can be medical fluid streams such as for example dialysate streams or blood streams, wherein the cassette has a sensor as a device for balancing the first and the second fluid stream, and wherein the sensor has a first channel for the first fluid stream and a second channel for the second fluid stream. The invention further relates to a dialysis system, which is configured to accommodate at least one cassette which is configured as described above. Furthermore, the present invention relates to an arrangement by which two channels for the first and the second fluid streams are formed. In addition, the invention relates to a method for construction of the two channels or the arrangement.

摘要： The present invention relates to a method for checking a dialyzer for the presence of a leak in the semipermeable membrane of the dialyzer, wherein the membrane divides the inner dialyzer space into a least one blood chamber and into at least one dialyzate chamber, wherein the blood chamber is flowed through by blood in the operation of the dialyzer and is in fluid communication with a blood-side line system and the vascular system of the patient, and wherein the dialyzate chamber is flowed through by dialysis fluid in the operation of the dialyzer and is in fluid communication with a dialyzate-side line system, wherein the method comprises the following steps: a) emptying the blood chamber or the dialyzate chamber of blood and of dialysis fluid respectively and keeping the fluid (blood or dialyzate) in the non-emptied dialyzate chamber or blood chamber; b) building up a test pressure by means of a gas, in particular by means of air, in the emptied blood chamber or in the emptied dialyzate chamber; and c) measuring the pressure drop over time in the emptied blood chamber or in the emptied dialyzate chamber or in the line system respectively in fluid communication therewith and/or measuring the pressure increase in the non-emptied blood chamber or in the non-emptied dialyzate chamber or in the line system respectively in fluid communication therewith or measuring the number of air bubbles or of a parameter correlated with the number of air bubbles in the non-emptied blood chamber or in the non-emptied dialyzate chamber or in a line system respectively in fluid communication therewith, wherein the steps a) to c) are carried out subsequent to the blood treatment of the patient and subsequent to the disconnection of the patient from the blood-side line system.

摘要： A bumper system with a bumper beam and two crash boxes, and two intermediate elements, wherein the intermediate elements have a first wall and a second wall that are arranged such that, from the perspective of direction x, the first wall points toward the exterior of the vehicle and the second wall points toward the interior of the vehicle, wherein walls are linked to each other at their one end in direction y, and wherein the linked ends point toward the exterior of the vehicle. The walls continue to be connected to at least one first support wall. The intermediate elements are arranged in the bumper system so that, in the event of a force striking the bumper beam in direction x, the intermediate element is deformed first and thereafter the crash box assigned to the intermediate element is subsequently deformed.

摘要： The present invention relates to an optimized fermentation process of coenzyme Q10, particularly to a fermentation process of coenzyme Q10 via flow feeding based on cooperative control of changes of online oxygen consumption rate and conductivity. During the fermentation process of coenzyme Q10 production strains, the oxygen consumption rate is controlled between 30-150 mmol/L·h and the conductivity is maintained between 3.0-30.0 ms/cm via flow feeding, so as to facilitate strain growth and the start of coenzyme Q10 synthesis and accumulation. The present invention can substantially increase output of coenzyme Q10 and greatly reduce the production cost with simple process control and strong operability, thus being applicable to large-scale industrial production.
