摘要： A blood treatment apparatus, including a blood treatment unit configured to receive untreated blood and fresh blood treatment fluid, and emit treated blood and used blood treatment fluid, a pair of fluid pumps configured to pass blood treatment fluid through the blood treatment unit, a pair of blood pumps 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, each blood pump including a pump chamber and a flexible member separating the pumping chamber into a first blood accumulating container and a second working fluid accumulating container where the flexible member is configured to vary a volume relationship between the first and the second accumulation containers. A control unit and a measuring device are configured to emit a feedback signal indicative of the amount of working fluid received into, or discharged from at least one of the second accumulation containers whereby the pumped mass or volume of working fluid is determined by the control unit at an arbitrary position of the flexible member.

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： It is disclosed 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 tool such as a milling or drilling tool includes a shaft having a front recess in which a cutting head is disposed. A drawbar disposed in the shaft includes a plurality of flexible tongues disposed in the recess. The tongues form a recess in which a rear knob of the cutting head is received. A retainer urges the drawbar axially rearwardly to retain the cutting head in the recess. The shaft includes axial projections at its front end which are received in respective rearwardly open recesses of the cutting head to prevent relative rotation between the shaft and the cutting head.

摘要： A metal cutting tool includes a holder arrangement, an indexible cutting insert seated on an insert-receiving site of the holder arrangement, and a screw for fastening the insert to the site. The bottom side of the insert includes more than two upright abutment surfaces arranged to abut respective upright support surfaces of the site, whereby the areas of contact formed by the mutually abutting surfaces lie inside of an outer perimeter of the insert. The abutment surfaces are oriented non-parallel to one another. The screw is arranged to urge the insert in a direction whereby less than all of the abutment surfaces abut respective support surfaces, and at least one abutment surface does not abut a support surface. When the insert is indexed, the non-abutting abutment surface is relocated and caused to abut a support surface when the screw is tightened, while an abutment surface that previously abutted a support surface becomes a non-abutting surface.

摘要： A metal-cutting tool comprises a holder, a clamp, and a metal-cutting insert. The holder includes a blade part which forms an upwardly facing seating surface extending in a front-to-rear direction. The holder includes a recess including a longitudinal axis extending in the front-to-rear direction at an angle relative to the seating surface, whereby an imaginary rearward extension of the seating surface converges toward the axis. The insert is mounted on the seating surface and the clamp has a rear portion which is slidable within the recess, whereby a front portion of the clamp pushes downwardly and rearwardly against a top surface of the insert. That top surface is shaped so that the front portion of the clamp is flexed upwardly relative to the rear portion when the rear portion is pushed rearwardly to the clamping position.
