Embodiment Construction

[0021] The figure shows an infusion cassette 10 which is designed as a disposable and can be inserted into a correspondingly formed recess or receptacle of a dialysis machine, preferably a cycler of a peritoneal dialysis machine. Reference numerals 2 , 4 , 6 identify connecting elements for connecting the solution bag to a line or drain line leading to the patient or the dialyzer. Two (not shown) rigidly fitted hoses are arranged on the connections 4 and 6 , one of which is a patient hose and the other is a drain hose. The connection element 2 is used for the connection to be carried out by an operator, for example to a solution bag or another medicine container.

[0022] The infusion box 10 contains a base body 12 which consists of plastic and can be produced using die-casting or deep-drawing technology. Recesses and channels extend in the base body 12 and partially form the walls of the two delivery chambers 20 , 22 arranged next to each other as well as the lines (for exam...

Abstract

The invention relates to a cartridge for conveying fluids, having connection elements for connecting fluid bags and lines leading to the patient or the dialysis device. According to the invention the cartridge has a controller for guiding fluid that is heated to above the target temperature, said controller being effective until the target temperature has again been reached. The invention further relates to a dialysis device having a unit for accommodating said cartridge, and to a method for controlling the temperature of the fluid guided in the cartridge.

Description

technical field [0001] The invention relates to an infusion cassette for conveying liquids, in particular dialysate, according to the preamble of claim 1 . Background technique [0002] From EP 991 05 771 B a corresponding infusion box is already known for delivering dialysate, which has: connecting elements for connecting the solution bag and the tubing leading to the patient and the dialyzer; at least one with an inlet and an outlet a pump chamber; and a line for conducting the supplied and delivered liquid, wherein the walls of the line are formed at least in sections such that the line can be closed by exerting pressure on the wall. This known infusion cassette contains a heating device for heating the dialysate to the desired target temperature. [0003] Infusion boxes of this type are used, for example, in the field of peritoneal dialysis, and here in particular in peritoneal dialysis in which the peritoneum is filled and emptied by means of a machine called a "circul...
