The present invention relates to a carbohydrate-based peritoneal dialysis fluid, containing a compound selected from the group consisting of glutamine, preferably L-glutamine; a dipeptide capable of releasing glutamine, L-glutamine in free form, preferably selected from the group consisting of glutaminyl-glycine, glycinyl-glutamine, glutaminyl-alanine, alanyl-glutamine; an oligopeptide consisting of two to seven glutamine, preferably L-glutamine residues; and mixtures thereof. The peritoneal dialysis fluids of the present invention are useful for inhibition of technical failure in a person undergoing peritoneal dialysis treatment.

The invention relates to a method of detecting symptoms of peritonitis, wherein the method comprises the following steps: taking a photo of a drainage solution and/or of a catheter exit site using a smartphone and/or inputting at least one query parameter which is input by a patient through the input zone of a smartphone; and, evaluating the photo and/or the query parameter.

Described herein are systems and methods for performing peritoneal dialysis. According to one aspect, the disclosure provides a sterile interface connection for connecting a water purification system to a disposable source of dialysate concentrates. The sterile interface connection can include a chamber comprising an inlet adapted to be connected to the water purification system on a proximal end and a valve on a distal end. The sterile interface connection can also include spring-loaded needle disposed in the chamber. The spring-loaded needle can move between a retracted configuration in which the spring-loaded needle is fully retracted into the chamber and the valve is closed and sealed, and an extended configuration in which the spring-loaded needle extends through the valve into the disposable source of dialysate concentrates.

A proportioning system includes a solute container filled with dry solutes, a source of water, a container of electrolyte concentrate, a fluid circuit connecting the solute container to the source of water and the container of electrolyte concentrate, the fluid circuit having an empty mixing container, a controller configured to transfer water from the source of water to the solute container through the fluid circuit so as to prepare a solute concentrate solution in the solute container. The controller is configured to transfer fluid from the container of electrolyte concentrate to a mixing container as well as a solute concentrate from the solute container to the mixing container and further adding water to said mixing container to form a medicament therein.

An apparatus for detecting the approximate number of leukocytes in a dialysate after the use thereof in peritoneal dialysis and for the analysis thereof, where the apparatus includes a housing having a through-opening for inserting a light-permeable tube and having an integrated tube clamping device, at least one laser light source directed onto the tube, a light detector device having a signal evaluation device, a display, and a power supply for the light source, the light detector device having the light signal evaluation device, and the display. The laser light source and the light detector device are arranged at an angle to one another such that the light detector device only detects the scattered radiation reflected from scattering surfaces of solid particles and in that an LED light source is also arranged, which directs the light thereof onto the light detector device which measures the transmitted light intensity and, after detecting turbidity of the dialysate, increases the value of the detected scattered radiation accordingly.

In some examples, a catheter assembly includes a catheter including an elongated catheter body defining a lumen, a first cuff and a second cuff. The first cuff includes a first cuff body comprising a material configured to promote epidermal tissue growth around or within the first cuff and an adhesive configured to adhere the first cuff body to an outer surface of the elongated catheter body at a first cuff position selectable by a user. The second cuff includes a second cuff body comprising the material configured to promote epidermal tissue growth around or within the second cuff body and an adhesive configured to adhere the second cuff body to the outer surface of the elongated catheter body at a second cuff position selectable by the user. A distance between the first and second cuff positions is customizable by the user based on a patient.

A method of peritoneal removal of electrolytes and inflammatory mediators. The method begins with infusing a treatment solution into the peritoneal cavity of a patient by way of a catheter. The treatment solution is drained from the peritoneal cavity by way of the catheter. During the draining, the treatment solution is filtered for removing electrolytes and inflammatory mediators.
