Adaptive system for blood fluid removal

Methods for monitoring patient parameters and blood fluid removal system parameters include identifying those system parameters that result in improved patient parameters or in worsened patient parameters. By comparing the patient's past responses to system parameters or changes in system parameters, a blood fluid removal system may be able to avoid future use of parameters that may harm the patient and may be able to learn which parameters are likely to be most effective in treating the patient in a blood fluid removal session.

20210093772 · 2021-04-01 ·

A blood treatment device includes an extracorporeal blood circuit, a dialyzer and a dialysis fluid circuit. The extracorporeal blood circuit and the dialysis fluid circuit are separated from each other by a membrane provided in the dialyzer, by which blood can be filtered. At least one substitution solution pump supplies a substitution solution to the extracorporeal blood circuit before and/or after the dialyzer. A control unit calculates a difference or a backlog between an ideal target volume and an actually controlled volume of the supplied substitution solution, and temporarily increases a controlled flow rate of the substitution solution pump under corresponding controlling thereof by a predetermined, fixed percentage which is less than or equal to 5%, until the difference or the backlog between the actually controlled volume and the ideal target volume no longer exists, i.e. the actually controlled volume corresponds to the ideal target volume.

Port, Rinsing Cap, Medical Treatment Apparatus, and System

The present disclosure relates to a port for establishing a fluid communication between at least one fluid line of the medical treatment apparatus, which fluid line is assigned to the interior of a medical treatment apparatus, and a connector of a fluid line of a fluid-guiding disposable, which fluid line is assigned to the exterior of the medical treatment apparatus, wherein the port includes at least a first fluid guide and a second fluid guide. The first fluid guide has at least a first lumen and a first end-side opening, which is provided for receiving and/or guiding a first, medical fluid and for establishing the fluid communication with the connector. The second fluid guide has at least a second lumen and a second end-side opening. The first end-side opening of the first fluid guide is arranged, at least in sections, in the second lumen of the second fluid guide.

Filtration system for preparation of fluids for medical applications

A system that fills multiple containers includes a filter with an inlet port and multiple outlet ports. The outlet ports are pre-attached to containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines is connected to a respective container interior. All of the respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. The system can produce batches of multiple sterile containers with sterile medicament in the containers.

10918776 · 2021-02-16 · ·

An apparatus for extracorporeal treatment of fluid and a process of setting up a medical apparatus for the delivery or collection of fluids are disclosed. According to the apparatus and the process, a control unit (10) is configured calculate set values of two or more of the fluid flow rates based on a fluid flow rate set by the operator and on a prescribed dose value (D.sub.set).

Dialysis device having means for recognizing a shunt recirculation

A dialysis device having an extracorporeal blood circuit which has an arterial line having a blood pump and an arterial needle for connection to a patient, a venous line having a venous needle for connection to a patient and a dialyzer arranged between the arterial line and the venous line and having a blood chamber and a dialysis fluid chamber is provided. The dialysis device furthermore has a control unit and an extracorporeal blood pressure sensor which is arranged at the suction side of the blood pump. The control unit is configured such that a signal output takes place which indicates the presence of recirculation when a change in the signal of the sensor following a trigger event exceeds a threshold value.

BLOOD PURIFICATION APPARATUS
20210213189 · 2021-07-15 ·

A blood purification apparatus capable of performing pre-substitution and post-substitution simultaneously is provided. A patient's blood flows through an arterial blood circuit and reaches a dialyzer. The blood purified by the dialyzer flows through a venous blood circuit and returns into the patient. A first substitution pump delivers substitution fluid through a substitution line to a branching point. A pre-substitution line connects the branching point and the arterial blood circuit to each other and is provided with a second substitution pump at a halfway position thereof. A post-substitution line connects the branching point and the venous blood circuit to each other and is provided with a check valve at a halfway position thereof. When the two pumps are activated simultaneously, the substitution fluid is supplied to the arterial blood circuit (pre-substitution). When only the first substitution pump is activated, the substitution fluid is supplied to the venous blood circuit (post-substitution). When the flow rate of the second substitution pump is set higher than the flow rate of the first substitution pump, pre-substitution and post-substitution are performed simultaneously.
