摘要： A portable artificial kidney designed for continuous use includes a catheter with filter properties. The body portion of the catheter has an infusion duct which opens into the surface of the catheter and is provided with surface channels which are covered by a semi-permeable membrane. Ducts are provided which communicate with the channels. One duct is operatively coupled to a suction pump to remove the filtrate. Another duct serves to supply a rinsing solution and the infusion duct serves to replace the liquid which has been filtered off.

摘要： The present blood flow monitoring and control apparatus is especially use in connection with the so-called single needle technique, for example, for treatments such as dialysis, perfusion, or diafiltration. The blood pressure control is accomplished by a measuring chamber including a pressure equalizing device operatively connected between the blood cleaning apparatus and the blood pump. Sensors are operatively connected to the volume measuring chamber. The volume sensors provide electric control input signals to a control circuit which in turn controls the blood pumps and/or valves. A reading may be provided on a display or an alarm may be given when the blood pressure or blood quantity or volume is not within predetermined limits as calculated by an electronic computer.

摘要： The present mass transfer apparatus between two media is especially adapted to blood dialysis. To assure an undisturbed flow of the blood through the dialyser and to avoid coagulation all flow channels are shaped to avoid dead corners and choking zones so that the blood is prevented from forming wakes or so-called "dead waters" in its flow path. For this purpose a hollow space is formed adjacent to the open ends of the hollow fibers. The inlet and/or outlet to this hollow space may extend radially axially or tangentially.

摘要： The ultra-filtration in a hemodialysis operation is controlled by a control apparatus which is connected to a balancing device (1) and to a dosing device (9) to form a closed loop control circuit for the metered supply of dialysis concentrate into the balancing device and for the metered supply of fresh dialysis solution into the dialyzer. The closed loop control circuit controls the alternating supply of fresh dialysis solution into one chamber of a balancing device and the withdrawal of used-up dialysis solution from the other chamber of the balancing device. The closed loop control circuit also controls a pump for the metered withdrawal of used-up dialysis solution out of the dialysis circulatory system. The dosing device operates as a proportionality device to produce fresh dialysis solution from water and dialysis concentrate whereby the concentrate is dosed and the dialysis solution is also dosed or metered.

摘要： The present electronic indicator or display device is equipped with adjustable upper and/or lower limit value markers to provide a respective alarm if such limit values are exceeded or not reached. The display itself comprises an electronic circuit and optical display elements such as light emitting diodes connected to the display circuit. An input to the display circuit is adapted to receive rated or limit value input signals which are displayed as respective markers and the position of which is adjustable. A time multiplexing circuit controls the timed sequence of the signals supplied to the display elements. A comparator compares the measured signal value with the rated value or values and monitors the proper function of the system.

摘要： An apparatus for controlling the ultra-filtration in connection with a hemodialysis treatment comprises a plurality of storage containers for the dialysis liquid. These containers are connected in parallel to each other and to the circulatory system of the dialysis liquid by groups of valves which are controlled by an automatic timer mechanism in such a manner that these containers are operatively connected to the circulatory system in a timed sequence. The groups of valves are operatively connected to the inlet and outlet ports of these containers. In addition to the main pump for circulating the dialysis liquid, there is a branching pump for withdrawing a dialysis liquid proportion from the system and a pump for filling the containers with a fresh dialysis liquid.

摘要： In peritoneal dialysis apparatus, flushing liquid is pumped into a supply vessel (4) which is then emptied into the body cavity through a valve (5) and a catheter (6). The supply vessel is then refilled while the cavity is drained back through the catheter into a receptacle (11) of the same weight and dimensions as the supply vessel. The supply vessel and receptacle are suspended at opposite ends of a balance beam (12) and when they are in balance after the receptacle has been filled, a valve (8) isolates the receptacle from the catheter and surplus fluid from the cavity is collected in a measuring vessel (15) through a valve (9), the receptacle being emptied through a valve (10).
