A peristaltic pump (1) including a tray, referred to as a pump body (3), which includes a substantially planar surface (32) against which a flexible tube (5) for the passage of fluid is intended to be positioned, and a system (2) for applying force including a plurality of support members (7), such as rollers, and drive elements for moving the support members against the tube in order to deform it against the pump body (3). The pump body (3) is movably mounted relative to the system (2) for applying force between a position spaced apart from the system (2) for applying force, and a position adjacent to the system (2) for applying force. The pump (1) also includes elements (36) for controlling the movement of the pump body (3) relative to the system (2) on the basis of a predetermined magnitude corresponding to the force applied to the tube.

A device and method are used for monitoring an extracorporeal blood treatment device, such as a dialysis machine, which includes an extracorporeal blood circuit having an arterial blood line with an arterial patient port and/or at least one venous blood line with a venous patient port, and a dialysis fluid system which has a dialysis fluid supply line and a dialysis fluid drain line. The monitoring device selects and senses a measured value during operation of the extracorporeal blood treatment device which is suitable for monitoring the blood treatment device to compare a time-related actual course of the measured value with a target course of the measured value stored in a memory, and to determine that there is a defect if, at least in sections, the actual course of the measured value deviates from the target course by more than a defined tolerance.

A method and a device are disclosed for regulating an ultrafiltration in a dialysis treatment, in which the blood to be ultrafiltered in an extracorporeal blood circulation (109) flows through a blood chamber (110) of a dialyzer (113), which is subdivided by a semipermeable membrane (111) into a blood chamber (110) and a dialysis fluid chamber (108), and dialysis fluid in a dialysis fluid circulation (109) flows through the dialysis fluid chamber (108) of the dialyzer (113). The device has a blood pump (115) for controlling a blood flow in the extracorporeal blood circulation (112), a dialysis fluid pump (107) for controlling a dialysis fluid flow in the dialysis fluid circulation (109) upstream or downstream from the dialyzer (113), for controlling the dialysis fluid flow upstream of downstream from the dialyzer, a balancing device (104) for setting up a fluid balance in the dialysis fluid circulation between an inflow (106) and an outflow (105) of the dialysis fluid chamber (113) as a measure of the ultrafiltration, as well as a regulating unit (101) for regulating the blood pump (115), the throttle (117) and/or the dialysis fluid pump (107). The pumps or the throttles (117) are regulated so that a predetermined ultrafiltration is achieved.

A patient monitoring system may be used with catheters to monitor the infusion and drainage of any solution into the human body. The system may be used, for example, with in-dwelling catheters for peritoneal dialysis in end stage renal disease (ESRD) patients, urinary tract catheters, insulin pumps in diabetic patients, feeding tubes and central venous line catheters. The patient monitoring system includes one or more fluid pathways for infusing into and/or draining solutions out of the catheter, and one or more sensors to monitor the fluid. The patient monitoring system transmits the patient monitoring data to a database, allowing data storage, processing, and access through graphical user interfaces to patients and providers via device applications or browser-based web access portals.

An extracorporeal blood treatment system may include a clamp coupled to a blood pathway extending between a patient and a reservoir, a sensor positioned along the blood pathway, and a control unit in communication with both the clamp and the sensor. The sensor is configured to sense a parameter of blood passing through the blood pathway and the sensor is configured to transmit a signal corresponding to the parameter to the control unit. The control unit is configured to receive the signal and transmit a signal to the clamp. The clamp is configured to receive the signal from the control unit and controllably adjust blood flow through the blood pathway in response to receiving the signal from the control unit.

An extracorporeal blood filtering machine can include a blood circuit, an effluent circuit, and a source fluid circuit and can be controlled by a controller. The extracorporeal blood filtering machine can also include access ports for connecting the source fluid circuit to the blood circuit, as well as blood sensors to detect possible issues with the extracorporeal blood filtering machine. The extracorporeal blood filtering machine can include density sensors and flow sensors that enable it to be more accurate and to operate while being transported. The extracorporeal blood filtering machine can further include a user interface and can display fluid inflow/outflow information. A medical fluid container can automatically empty after being filled. An apparatus for supporting a medical fluid container can include a hanger and an attachment member with the apparatus able to adjust to ensure the medical fluid container remains properly oriented directly under a medical fluid container scale.

Extracorporeal life support (ECLS) systems, devices and methods wherein a portable ECLS device is used to deliver cardiovascular support to a humans or animal patient (or harvested organ(s)) during pre-hospital or inter-hospital transport.

A differential flow-meter for measuring the weight loss in dialysis treatments. The differential flow-meter is of the thermal anemometer type.

An apparatus is described for extracorporeal blood treatment, comprising a treatment unit, an extracorporeal blood circuit and a fluid evacuation line. The apparatus comprises a control unit connected to a pressure sensor and a blood pump, the blood pump generating a variable flow with a constant component and a variable component. The control unit receives, from the pressure sensor, a plurality of values and calculates the average pressure value, acquires an estimated value of volume variation in the expansion chamber connected to the variable flow component, calculates, as a function of the pressure values, an estimated value of pressure variation in the expansion chamber that is representative of an oscillating pressure component and determines a representative magnitude of a blood level in the expansion chamber as a function of the average pressure value, the estimated value of volume variation and the estimated pressure variation in the expansion chamber.

A system is provided for processing blood from a blood source. The system cooperates with a disposable fluid flow circuit including a tubing line that is associated with a clamp of the system. The system also includes a sensor and a controller, which cooperate to determine whether the fluid flow circuit and/or the system itself is defective and/or if the fluid flow circuit has been installed onto the system improperly. If such an error or defect exists, then the controller determines whether a selected system state exists. The controller causes a change in the appearance of the display of the system, which includes displaying an interactive icon if the selected system state exists. The icon, when manipulated, causes the clamp to move from the closed condition to an open condition.
