摘要： A circuit for extracorporeal blood treatment in which a flow-inverting device is interposed between a blood treatment unit and a blood pump placed on an artery branch connected with a vascular access of a patient. The flow-inverting device allows the blood flow within the filtering unit to be kept unchanged even following an inverted circulation in the patient-side artery and vein branches controlled by the blood pump.

摘要： A cutting insert is clamped in a pocket of a holder by a top clamp assembly which includes a clamp arm screwed to the holder, and a clamp plate interposed between the insert and a front part of the clamp arm. The clamp plate is formed of a harder and more wear-resistant material than the clamp arm and transmits clamping forces from the clamp arm to the cutting insert. The hard clamp plate shields the clamp arm from being impacted by chips generated during a machining operation, thereby minimizing wearing of the clamp arm.

摘要： A tool holder for mounting a cutting insert for chip removing machining includes a head on which is disposed an insert-receiving seat having an insert-support surface. A plate-shaped member is detachably mounted on the head and includes first and second fingers. The fingers include respective first and second side surfaces forming a recess therebetween. The side surfaces are arranged in upstanding relationship with the insert-support surface to form therewith the insert-receiving seat. The first finger includes a through-slot and is flexible, wherein the first side surface is elastically displaceable relative to the second side surface. An intermediate portion of each of the side surfaces includes a recess wherein each of the side surfaces defines a plurality of spaced-apart contact areas. The plate-shaped member and the head include serrations which are in meshing relationship, except at locations which permit the first finger to be elastically deformed relative to the second finger, by an adjusting screw.

摘要： A holder includes a seat which removably carries a cutting insert for chip removing machining. The seat can be widened by the manual application of a force to enable the insert to be replaced. The force is applied by a manually actuable key which includes a shaft and an expansion mechanism mounted on an end of the shaft. The expansion mechanism includes a plate which is mountable to the holder in a manner enabling a projection pin of the shaft to enter a slot which constitutes an extension of the insert seat. The portion of the pin entering the slot has an out-of-round cross sectional shape. By rotating the shaft relative to the plate, the pin rotates to widen the slot, and thus to widen the seat. Rotation of the shaft relative to the plate is terminated after a predetermined amount of rotation, in response to mutual engagement between stop surfaces disposed on the shaft and the plate, respectively.

摘要： A clamping arrangement includes a holder blade having a body portion, the body portion having a key slot and a key recess are disposed relative to each other and relative to an insert-receiving slot such that, when a first keying member of a key is received in the key slot and the second keying member of the key is received in the key recess and the key is moved from an at-rest position to an opening position, the height of the insert-receiving slot is increased against resilient forces of the body portion to a sufficient height to install an insert for the holder blade and, when the key is returned to the at-rest position, the resilient forces cause the height of the insert-receiving slot to decrease and clamp the insert between the upper and lower surface of the insert-receiving slot.

摘要： Reaming tool includes a head and one or more detachable cutting inserts fixed in seats. The seat includes radial, tangential and axial support surfaces, while the cutting insert has a mirror-symmetrical polyhedron shape comprising six limiting surfaces, viz. two chip surfaces and four clearance surfaces, a number of alternately usable identical cutting edges formed in the transitions between the chip and clearance surfaces. The cutting insert has a rhombic cross-sectional shape with four clearance surfaces, which meet each other in pairs at obtuse angles in two opposite corners, and which, along each individual chip surface, form two cutting edges alternately usable by indexing the cutting insert. The seat additionally includes a slope surface forming an obtuse angle with the radial support surface, suitably of the same magnitude as the obtuse angle between the clearance surfaces of the cutting insert. Tool head and reaming insert for the tool are disclosed.

摘要： A proposed blood treatment apparatus includes: a blood treatment unit, a pair of fluid pumps and a pair blood pumps. The blood treatment unit is configured to receive untreated blood and fresh blood treatment fluid, and emit treated blood and used blood treatment fluid. The fluid pumps are configured to pass blood treatment fluid through the blood treatment unit. The blood pumps are configured to extract untreated blood from a blood source, pass extracted blood through the blood treatment unit and deliver treated blood to a target vessel. Additionally, the fluid pumps are configured to control the operation of the blood pumps via the blood treatment fluid. Moreover, a flow control device is configured to control a trans-membrane flow between the blood side and the a fluid side of the blood treatment unit. Hence, for instance ultrafiltration can be adjusted to a desired level in a very straightforward manner.

摘要： A blood access device including a fluid conduit configured to convey a flow of fluid to a target vessel, a second lever element pivotally and resiliently connected to a first lever element such that it may move from a first position to a second position. A biasing force is exerted on the second lever element for moving it from the first position to the second position, and a blocking member may be activated by the second lever element, such that a flow of fluid is decreased when the second lever element is moved from the first position to the second position. The lever elements are configured to be fixed to the target vessel when the second lever element is in the first position, and the second lever element moves to the second position and activates the blocking member if the fixation is at least partially lost.
