The invention relates to a method of detecting symptoms of peritonitis, wherein the method comprises the following steps:

Method of detecting symptoms of peritonitis

A device for detecting moisture for an arrangement for monitoring an access to a patient for a system by which, via a flexible line, a liquid is fed to a patient and/or a liquid is fed out from the patient, and in particular for monitoring the vascular access in extra-corporeal blood treatment and particularly for monitoring a central venous catheter for acute dialysis includes at least a portion which can be deformed into a sleeve and placed around the circumference of the flexible line or of a connecting system. The portion in sleeve form has fastening means for fixing it in place in the position in which it surrounds the flexible line or the connecting system. The portion in sleeve form allows the device to be fastened quickly and securely to a flexible line or a connecting system.

Device for detecting moisture for an arrangement for monitoring an access to a patient

A moisture sensor for monitoring an access to a patient for a system by which, via a flexible line, a liquid is fed to and/or out from a patient, for monitoring the vascular access in extra-corporeal blood treatment or for monitoring a central venous catheter for acute dialysis, and a method of producing a moisture sensor are described. The moisture sensor has a substrate material with an electrically conductive structure having conductor paths arranged at a distance from one another and connected together across a terminating resistor. The terminating resistor is an electrically conductive film which is applied in a section of the substrate material on which are formed electrical contacting regions for connecting the terminating resistor to the conductor paths, such that an external terminating resistor is not required and the moisture sensor can be produced easily in large numbers complete with the terminating resistor.

A terminal clamp for a moisture sensor to be placed on a patient's skin in order to monitor a vascular access to a patient includes first, lower and second, upper legs for clamped fixing of terminal tab of moisture sensor, rear end pieces of the legs being connected. The terminal clamp includes terminal contacts for contacting electrical contact points of terminal tab, and a guide piece having a slot-shaped cutout for receiving terminal tab. Slot-shaped cutout of guide piece is bounded laterally by two stop elements so that terminal tab is held in terminal clamp in a predetermined position, in which terminal contacts of terminal clamp contact the electrical contact points of terminal tab. Upper leg comprises a latching device, which is fixed in slot-shaped cutout in a snap-in manner when terminal clamp is closed to lock upper leg in position on lower leg.

A method for the depletion of at least one component of a fluid medium includes increasing the concentration of the at least one component to be depleted before its depletion. An apparatus for the depletion of the at least one component of the fluid medium has a concentration increasing unit for increasing the concentration of the component of the fluid medium to be depleted and a depletion unit disposed downstream thereof and in fluid communication therewith for the subsequent reduction in the concentration of the component to be depleted.

The present invention relates to a method for determining the composition of medical liquids with regard to their fraction of electrolytes and non-electrolytes, comprising the steps of: determining at least one first physical parameter of the medical liquid for unambiguously determining the fraction of non-electrolytes in the medical liquid; simultaneously determining at least a second physical parameter of the medical liquid for determining the fraction of electrolytes in the medical liquid; and determining the fraction of electrolytes and non-electrolytes in the medical liquid based on the first and second physical parameter. The present invention further relates to an apparatus for determining the composition of medical liquids with regard to their fraction of electrolytes and non-electrolytes, comprising a first measuring apparatus () for measuring a first physical parameter of the medical liquid, which is unambiguously related to the non-electrolyte in medical liquid, a second measuring apparatus () for determining at least a second physical parameter of medical liquid, which is unambiguously related to the fraction of electrolytes in the medical liquid, and an evaluating apparatus () for determining the fraction of electrolytes and non-electrolytes in the medical liquid on the basis of the measured values of the first measuring apparatus () and the second measuring apparatus ().

An apparatus is disclosed for detecting moisture, which is intended for the use in an apparatus for monitoring an access to a patient for a device by means of which a fluid is conducted to and/or removed from a patient via a hose line, in particular for monitoring the vascular access during an extracorporeal blood treatment, wherein blood of a patient is removed from the patient via an arterial hose line, which has an arterial puncture cannula, and is conducted back to the patient via a venous hose line, which has a venous puncture cannula. The apparatus for detecting moisture is designed as a pad which is made of a flexible material and is to be applied onto the patient's skin and which comprises an upper side facing away from the patient's skin and a lower side facing the patient's skin. The pad comprises an opening for the passage of fluid, in particular blood, and a moisture sensor having contact elements for the connection of the same. The moisture sensor is capable of detecting blood flowing through the opening to the surface of the pad. The apparatus according to the invention is characterized in that the lower side of the pad is impervious to fluid.

The invention concerns a device for the extracorporeal irradiation of a patient's (P) bodily fluid containing bilirubin, comprising a first () and a second () line which can be connected to the patient (P), an impermeable irradiation unit for bodily fluids () connected therewith and located between the first () and the second () lines, and at least one adjustable feed unit for bodily fluids () located in the first () and/or the second () line, wherein by means of at least one feed unit for bodily fluids () an adjustable flow of bodily fluid through the lines () and the irradiation unit for bodily fluids () is achievable, in which the first line () is designed to continually circulate the bodily fluid drawn from the patient (P) and route it to the irradiation unit for bodily fluids (), and the second line () is designed to continually circulate the irradiated bodily fluid to the patient (P), and in which the irradiation unit for bodily fluids () contains an radiation source for the emission of electromagnetic radiation with a wavelength greater than 430 nm, preferably in a spectrum from 450 to 530 nm. The invention furthermore concerns a corresponding method.

Device for extracorporeal irradiation of a liquid containing bilirubin, and method therefor

A blood purification device has a blood purification element divided into two chambers by a semipermeable membrane, with a first chamber as part of a dialysis fluid loop and a second chamber as part of an extracorporeal blood loop. By virtue of an analysis unit operatively connected to a sensor in the dialysis fluid loop, the device provides simple and uncomplicated determination of the blood purification performance of the blood purification element for a second material by derivation from a previously established blood purification performance for a first material. In this way, the device also determines the blood concentration of the second material during the blood treatment through measurements in the dialysis fluid without intervention in the treatment sequence.
