A tube connector is configured to connect between a main tube and a peristaltically-actuated tube. The tube connector includes a first connection part configured to be connected to the main tube; a second connection part configured to be connected to the peristaltically-actuated tube; a communication part being provided between the first connection part and the second connection part and having a communication flow path for communicating between a first flow path through which fluid flows in the first connection part and a second flow path through which the fluid flows in the second connection part; and a main body section. The first flow path and the second flow path are formed to have a constant diameter and are formed so as to extend along the axial direction of the main body section. A diameter of the first flow path is smaller than a diameter of the second flow path. The communication flow path is formed so as to gradually enlarge in diameter from a first flow path side to a second flow path side. A central axis of the first flow path and a central axis of the second flow path are shifted toward the radial direction of the main body section.

A drip chamber is provided that includes a hollow body and a nucleation column extending into the interior of the hollow body or formed on the inner surface of a drip chamber sidewall. The nucleation column can be formed with, or treated by a treatment to include, microfeatures or other surface properties that provide nucleation sites for the nucleation and amalgamation of microbubbles. The drip chamber can include a bubble catcher in the bottom of the hollow body and the nucleation column can extend from the bubble catcher into the interior of the hollow body. Methods of making such drip chambers are also provided.

Embodiments of the present disclosure include a dialysis system having a disposable cartridge which includes one or more flowpaths arranged on or within the cartridge.

A blood processing apparatus may include a heat exchanger and a gas exchanger. At least one of the heat exchanger and the gas exchanger may be configured to impart a radial component to blow flow through the heat exchanger and/or gas exchanger. The heat exchanger may be configured to cause blood flow to follow a spiral flow path.

The document describes a system which is easy to move in order to allow travelling anywhere in the world. The document provides different potential features and embodiments such as the container support, the loading system, the shape of the housing, . . .

Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

A system for generating a blood circulation in at least part of an organ of a vertebrate, including a first artificial cavity and a second artificial cavity. The cavities each include a flexible membrane capable of beating under the action of a gas. Each of the membranes separate in a sealed manner a blood circulation chamber and a chamber containing the gas. The system also includes: a first low pressure gas buffer reservoir; a second high-pressure gas buffer reservoir; a gas distribution; and a pneumatic pump.

A blood processing apparatus may include a heat exchanger and a gas exchanger. At least one of the heat exchanger and the gas exchanger may be configured to impart a radial component to blow flow through the heat exchanger and/or gas exchanger. The heat exchanger may be configured to cause blood flow to follow a spiral flow path.

An implantable heart help device adapted for implantation in a human patient is provided. The device comprising a fixating member adapted to fixate said device to a part of the human body comprising bone. Further a method of fixating an implantable heart help device in a human patient is provided. The method comprises the steps of: cutting the skin of said human patient, dissecting an area of the body comprising bone, and fixating said implantable heart help device to said part of the body comprising bone.
