Problems solved by technology

This presents the disadvantage of a complex and costly dialysis machine which is at increased risk of failure by virtue of its complexity.
Increased maintenance is also a problem since it is essential to minimize machine downtime in order to most efficiently treat the patient.
A further problem with known hemodialysis machines is that the blood and dialysate solution lines require careful mounting onto the dialysis machine before the treatment can commence.
This presents a risk that the lines are not correctly installed, a risk which is particularly relevant to those patients who dialyse at home.
This method of dialysis also presents an increased risk of cross-infection between patients since the disposable blood and dialysate lines come into contact with the dialysis machine.

Embodiment Construction

[0052]In FIG. 1 a dialysis machine 1 is shown having a cover 2 which opens to reveal a storage compartment 3. The machine has an engine section 4 which receives a dialysis cartridge 10.

[0053]Referring now to FIG. 2, the engine section 4 is shown in further detail to include first and second platens 5, 6 which dose upon insertion of the cartridge 10 into the machine to retain the cartridge in position in use. The engine 4 has pneumatic actuators 7 and sensors (indicated generally at 8 in FIG. 2) arranged on the second platen to control operation of the cartridge 10 as will be described in further detail shortly.

[0054]In FIGS. 3 and 4 a dialysis cartridge 10 is shown having a pumping portion 12 (to the right of dashed line I-1 in FIG. 4) and a dialysis portion 14 (to the left of dashed line I-I in FIG. 4). The pumping portion 12 has the form of a fiat rectangle. The dialysis portion 14 has a dialyser cover 15 which is shaped so as to contain a dialyser as will be described in further ...

Abstract

A disposable cartridge for use in a hemodialysis machine has a blood flowpath for carrying a volume of blood to be treated in a dialyseer and a dialysate flowpath, isolated from the blood flowpath, for delivering a flow of dislysate solution through the dialyser. The cartridge is received in an engine section of the machine. The engine section has first and second platens which close when the cartridge is inserted to retain the cartridge. Actuators and sensors arranged on the second platen control operation of the cartridge.

Description

[0001]This application is a continuation of U.S. application Ser. No. 11 / 919,694, filed Oct. 31, 2007, which in turn is a U.S. national stage application of International Application No. PCT / GB2006 / 001668 with an International filing date of May 8, 2006 and a priority date of May 6, 2005.FIELD OF THE INVENTION[0002]The present invention relates to dialysis machines and in particular, but not exclusively, to a disposable cartridge for use in hemodialysis machine.BACKGROUND OF THE INVENTION[0003]Dialysis is a treatment which replaces the renal function of removing excess fluid and waste products, such as potassium and urea, from blood. The treatment is either employed when renal function has deteriorated to an extent that uremic syndrome becomes a threat to the body's physiology (acute renal failure) or, when a longstanding renal condition impairs the performance of the kidneys (chronic renal failure).[0004]There are two major types of dialysis, namely hemodialysis and peritoneal dial...
