A fluid flow sensing and bubble detecting apparatus includes a housing comprising a channel configured to receive a tube through which fluid flows; a sensor apparatus disposed within the housing, which includes a first sensor operable to measure flow rate of fluid and to detect bubbles in flowing fluid; and a temperature sensor operable to detect temperature of the flowing fluid; and a processor connected to receive fluid flow rate data obtained by the first sensor, to receive bubble detection data obtained by the first sensor, and to receive fluid temperature data obtained by the temperature sensor, wherein when a tube through which fluid flows is disposed in the channel of the housing, the first sensor measures the flow rate of the flowing fluid and detects bubbles therein, and the temperature sensor measures the temperature of the flowing fluid, and the processor calculates in a short period of time a fluid flow rate corrected for temperature. All sensors are non-invasive and have no direct contact to the fluid in the tube, which might be blood. In accordance with additional embodiments, the fluid flow rate is additionally corrected for hemoglobin or hematocrit, and the effect of oxygen saturation on the hemoglobin or hematocrit data.

The invention relates to a blood treatment device for carrying out an extracorporeal blood treatment in which blood is guided in a blood guidance device having a main blood line and at least one secondary line, the latter being fluidically connected to the main blood line and the main blood line having a dialyzer and, downstream from the dialyzer, a blood treatment element, wherein the blood treatment device has a control device; and a pump configuration, which is equipped for generating blood flows in the main blood line and also in the at least one secondary line, wherein the control device is designed to operate the pump configuration in such a way that a first blood flow rate in the dialyzer is decoupled from a second blood flow rate in the blood treatment element. Furthermore, the invention relates to a blood guidance device for cooperation with the blood treatment device as well as for a blood treatment system.

The present invention relates to a system (100) for extracorporeal blood treatment comprising a first inlet (1) for introducing a bloodstream to be treated into the system (100), three blood treatment apparatus (A, D, G), as well as an outlet (2) for discharging a treated bloodstream from the system (100), wherein the system comprises an adsorber apparatus (A) and/or a plasma separator apparatus, a dialysis apparatus (D) and a gas exchange apparatus (G), and wherein the three blood treatment apparatus (A, D, G) are sequentially connected in series in a functional state of system (100) application between the inlet (1) and the outlet (2) of the system relative to a direction of blood flow of a bloodstream to be treated and can be consecutively perfused extracorporeally by a bloodstream to be treated. The present invention further relates to a treatment apparatus comprising such a system, a kit comprising the components of such a system, a method for operating such a system (100) as well as a method for extracorporeal blood treatment with such a system (100).

An infusion device includes an infusion pump and an infusion tube assembly. The infusion tube assembly includes a first tube body connected to the infusion pump, a tube joint structure having first, second and third tube joints, a second tube body, and a clamping device on the second tube body. The clamping device is to clamp the second tube body. An infusion method includes instructing the infusion pump to perform an infusion operation. When bubbles are detected in a liquid in the infusion tube assembly, the infusion pump is instructed to stop the infusion operation and a bubble alarm is generated. After the infusion pump stops the infusion operation, it is determined whether a pressure of the liquid first drops to a first pressure value and then rises to a second pressure value. If yes, a rinsing operation is performed.

Embodiments of the disclosure provide a system and method for detection of a transient air bubble in an arterial blood flow path during dialysis (e.g., hemodialysis). The system uses measurements from an optical sensor to remove one or more effects of common factors affecting the absorbance of the light incident on the arterial tubing. These factors include color of medium within the arterial tubing, tubing color, angle of illumination, and temperature of the optical detector. A variance of the measurements from the optical sensor are used to determine whether an air bubble is present.

The specification discloses a portable dialysis machine having a detachable controller unit and base unit. The controller unit includes a door having an interior face, a housing with a panel, where the housing and panel define a recessed region configured to receive the interior face of the door, and a manifold receiver fixedly attached to the panel. The manifold includes diaphragms adapted to minimize the dead space between the dialysis machine pins and improve responsivity. The base unit has a planar surface for receiving a container of fluid, a scale integrated with the planar surface and a heater in thermal communication with the container. Embodiments of the disclosed portable dialysis system have improved structural and functional features, including improved modularity, ease of use, and safety features.

A portable medical apparatus for cardiopulmonary aid to patients includes a transportable machine body that integrates an heater/cooler unit and an extracorporeal circuit for circulating the blood of a patient. The extracorporeal circuit includes a line for drawing venous blood from the patient, a line for returning arterial blood to the patient, a pumping unit for pumping blood along the extracorporeal circuit, a heat exchanger for thermoregulating blood in the extracorporeal circuit, and an oxygenator unit for blood oxygenation.

The present invention relates to a medical device, in particular to a blood treatment apparatus, having a control and processing unit, having at least one structure-borne sound emitter and having at least one structure-borne sound sensor, each configured for coupling to coupling points of a medical tubing kit which can be coupled to the medical device, wherein the filling level of a bubble chamber arranged in the tubing kit can be determined at the tubing kit via the control and processing unit based on the measurement of the structure-borne sound.

An apparatus for providing an extracorporeal blood circuit control includes a base module having a control device and a patient module releasably connected to the base module and having blood-conducting components of the extracorporeal blood circuit. A pivot system is also provided at the base module and at the patient module to pivot the patient module relative to the base module about a horizontal axis.
