A manifold assembly for a peritoneal dialysis apparatus, comprises: a casing delimiting internally a first compartment and a second compartment; a yielding pump tube having a first end connected or connectable to the first compartment and a second end connected or connectable to the second compartment. The yielding pump tubes extends outside the casing to be coupled to a peristaltic pump of a cycler of a peritoneal dialysis apparatus. The second compartment delimits expansion chambers configured to attenuate pressure pulsations from the peristaltic pump.

A method for calibrating a peristaltic pump in a medical apparatus comprises: rotating the peristaltic pump of a predetermined rotation to pump a liquid from a fluid source from a first compartment into a second compartment of a manifold assembly, raising a level of the liquid in the second compartment and compressing air in an air buffer volume of the manifold assembly; measuring a pressure of air in the air buffer volume; calculating, from the measured pressure, a variation of liquid volume in the second compartment due to the rotation of the peristaltic pump; calculating, from the variation of liquid volume and the predetermined rotation, a stroke liquid volume of the peristaltic pump.

The present disclosure relates to a medical system for specifying adjustable setting of a blood treatment apparatus having a calculation device with an input interface for entering and/or reading in the results determined by a diagnostic device for executing a retinal vessel analysis of a patent, respectively; an output interface for outputting at least one technical parameter value for the treatment of the patient and/or outputting at least one target treatment parameter value for a treatment of the patent using the blood treatment apparatus, and/or for outputting suggested changes of existing pre-set or pre-settings for the technical parameter value and/or for the target treatment parameter value.

A dialysis machine that includes a valve member having a deformable area configured to deform outwardly away when pressurized fluid is introduced into the valve member. The valve member is configured so that, when a dialysis fluid cassette is disposed in a cassette compartment of the dialysis machine and pressurized fluid is introduced into the valve member, the deformable area obstructs a fluid channel of the dialysis fluid cassette to control dialysis fluid flow therethrough.

IV sets including a plurality of hand pumps and methods of use thereof are described herein. An IV set includes a first portion of tubing, a second portion of tubing, and a drip chamber. The drip chamber includes a spikeless inlet fluidically coupled to the first portion of the tubing, an outlet fluidic ally coupled to the second portion of the tubing, and a curved drop former positioned within the drip chamber between the inlet and the outlet. The curved drop former is configured to receive a fluid via the spikeless inlet and form, based on a curvature of its surface, one or more droplets having a substantially uniform consistency and flowing at a substantially constant rate through the drip chamber.

A blood purification apparatus includes a line section, a duplex pump, and a control unit. The line section includes a dialysate introduction line and a drain-liquid discharge line. The control unit executes a blood purification treatment process and a defatting washing process. The blood purification treatment process is executed when blood purification treatment is performed in which dialysate is delivered to a dialyzer. The dialysate is prepared by diluting an A-drug solution and a B-drug solution. The defatting washing process is executed when defatting washing is performed where oil and fat in the line section is removed by causing a sodium carbonate solution obtained from the B-drug solution introduced into the line section to flow through the line section. The control unit uses a heating unit and a deaerator when executing a bicarbonate-solution-generating process where the sodium carbonate solution is generated by a predetermined amount while carbon dioxide is discharged.

Methods, device, and systems for preparing peritoneal dialysis fluid and/or administering a peritoneal dialysis treatment are disclosed. In embodiments, peritoneal dialysis fluid is prepared at a point of use automatically using a daily sterile disposable fluid circuit and one or more long-term concentrate containers that are changed only after multiple days (e.g. weekly). The daily disposable may have concentrate containers that are initially empty and are filled from the long-term concentrate containers once per day at the beginning of a treatment.

A filter for medical infusion lines includes a box-like body having an inlet connector and inside which there is arranged a plate-like element on whose one or both opposite faces there are formed respective channels placed in communication with an outlet connector. Filtering hydrophilic membranes separate the channels from at least one interspace placed in communication with the inlet connector. With the outlet connector there is operatively associated an overpressure valve incorporated in the box-like body of the filter.

A fluid reservoir system is provided. The fluid reservoir system includes a fluid reservoir that defines a chamber to receive a fluid, and the fluid reservoir includes an outlet. The fluid reservoir system includes a source of pressure to draw the fluid into the outlet and a wicking membrane is coupled to the fluid reservoir that covers the outlet.

A canister for use with a wound therapy system includes first and second compartments configured to receive and contain wound exudate, and an airflow pathway. The airflow pathway includes a planar region positioned between the first compartment and the second compartment, an inlet extending from a first end of the planar region at an obtuse angle relative to the planar region, an outlet at a second end of the planar region.
