摘要:
An air separator for liquid containing gas bubbles having an essentially cylinder-shaped chamber through which liquid, such as blood, flows essentially in helical flow paths, with the result that air bubbles are driven in a radial direction relative to the longitudinal axis of the chamber because of pressure differences produced by centrifugal forces. The inlet and outlet of the chamber of the air separator are coaxial relative to each other in the longitudinal axis of the chamber. The air separator also includes a flow-deflection component or influx distributor, which includes a rotation-symmetrical base body element whose outer surface faces inflowing liquid as a first deflection surface, which is geometrically defined by rotation of a curve section about the longitudinal axis of the chamber. The first deflection surface has deflection surface deflector vanes, which are curved in planes perpendicular relative to the longitudinal axis of the chamber, with the result that axially inflowing liquid is deflected so that desired helical flow development is induced.
摘要:
A connector for packings containing medical liquids, particularly infusion, transfusion or enteral bags, comprises a connecting part (1) for accommodating a spike for drawing out the liquid and comprises a closure part (3) that closes the passage (2) inside the connecting part (1). The connecting part (1) has an elastically deformable pinching off part (4) provided in the form of a tubular section with a non-circular cross-section. A base part (5), which widens on both sides is adjoined to said pinching off part (4) and can be integrated in the packing. During manufacturing, the packing is filled with liquid via the connecting part. After filling, the pinching off part is pressed together whereby preventing liquid from escaping. Afterwards, the closure part is placed onto the connecting part. The manufacturing of the packing is simplified by virtue of the fact that an additional tube for connecting the connector and packing is rendered unnecessary.

摘要:
A closure element for sterile closure of connections, in particular connections of filter modules for dialysis, hemofiltration or ultrafiltration is described. A closure element with a simple design that provides a reliable seal is formed by having the closure element include a wall with an automatically closing slit-shaped indentation which when closed creates a germ-proof seal. The sealing element is used for sterile closure of connections of medical items, as well as for the medical items themselves.
摘要:
A dialyzer is formed by first placing a film strip into a membrane hose and then simultaneously folding the hose and a netting intermediate layer so that the folds of the hose and the folds of the netting extend crosswise relative to each other in a mutually interlocking manner. The facing ends of the hose layers are then sealed with a curable sealing compound and severed. Then the film strips are withdrawn from the hoses in the so formed package. The resulting product is a dialyzer or hemofilter, depending on the type of membrane hose used, in which the facing ends of the membrane hoses are open for the passage of blood therethrough, after the withdrawal of the film, and in which the netting layers are located between adjacent hoses.
