According to the apparatus and the process, a control unit () is configured calculate set values of two or more of the fluid flow rates by imposing that an emptying time of containers of fresh fluid () and/or a filling time of a waste container is substantially same as, or multiple of, the emptying time of one or more of the other containers of fresh fluid.

Medical apparatus for extracorporeal treatment of fluid and a process of calculating set flow rates in a medical apparatus for delivery or collection of fluids

The invention relates to a blood line () comprising an infusion site () intended to inject into the line a solution comprising: &#x2014;a first main channel () having a first passage section, &#x2014;a second main channel () having a second passage section, &#x2014;means for the formation () of a turbulence area located downstream from the first main channel, located upstream from the second main channel, these formation means comprising a first fluid passage means () defining a reduction () in the passage section and whose smallest passage section is smaller than the first passage section and smaller than the second fluid passage section, &#x2014;a secondary channel () comprising an inlet () for letting in the solution and an outlet () in fluid communication with the first main channel or the means for the formation of a turbulence area or the second main channel.

The blood treatment apparatus described herein include a plurality of treatment solution reservoirs connected to a junction which feeds an output controller through an output line. The reservoirs feed the junction through one or more liquid-gas separation filters that limit or prevent air from passing. One or more of the reservoirs can typically be emptied during a treatment session without drawing air into the system.

Device for controlling blood circulation for a single needle circuit

A description is given of a gas separation device for a physiological fluid, comprising a containing body () having at least a first inlet aperture () for a physiological fluid, positioned with a tangential direction of access, at least one outlet aperture () for the said fluid, spaced apart from the said inlet aperture, and a guide element () housed within the said body. The guide element () has a continuous active surface () designed to contact and guide the said fluid and delimits, together with the containing body (), a first annular chamber () into which the first inlet aperture () opens directly.

Gas separation devices

An integrated CRRT method and apparatus incorporates steps and means for compensating for heat loss from blood in an extracorporeal circuit. A blood warmer is designed to engage and hold a disposable blood tube segment to transfer heat at a closely controlled temperature to blood flowing in the disposable blood tube segment. Another significant aspect of the present invention is a blood tube segment for engagement with the blood warmer is located in downstream of a dialyzer and upstream of a venous pressure monitor, an air bubble detector and a venous line clamp. The disposable blood tube segment may be selectively connected when heat loss compensation is required and left disconnected when heat loss compensation is not required.

A device for preparing a sterile liquid includes structure for validating a sterilization treatment applied to the liquid. The validating structure includes structure for calculating, from at least one operating parameter of the device, a parameter representing a sterilizing value for the sterilization treatment, and structure for comparing the calculated parameter to a threshold value corresponding to the sterility of the liquid.

Process and device for sterilizing and dispensing a liquid for medical use

A liquid treatment apparatus includes a sensor which is sensitive to a variation in gas pressure and which generates signals indicative of sensed pressures. The apparatus also included a casing divided into a first compartment and a second compartment by a flexible membrane, the first compartment having at least one orifice for the introduction of the liquid, and the second compartment being connectable in a leaktight manner to the pressure sensor. A pump is provided to vary a quantity of gas in the second compartment, and a controller is provided to regulate the pump as a function of variations in pressure generated in the second compartment. The controller is configured to receive signals from the sensor and to cause, through the pump, at least two successive pressure variations, having opposite directions, in the second compartment so as to adjust said position of the membrane between a wall of the casing bounding the first compartment and a wall of the casing bounding the second compartment.
