摘要： An impeller includes a hub and at least one blade supported by the hub. The impeller has a stored configuration in which the blade is compressed so that its distal end moves towards the hub, and a deployed configuration in which the blade extends away from the hub. The impeller may be part of a pump for pumping fluids, such as pumping blood within a patient. A blood pump may include a cannula having a proximal portion with a fixed diameter, and a distal portion with an expandable diameter. The impeller may reside in the expandable portion of the cannula. The cannula may have a compressed diameter which allows it to be inserted percutaneously into a patient. Once at a desired location, the expandable portion of the cannula may be expanded and the impeller expanded to the deployed configuration. A flexible drive shaft may extend through the cannula for rotationally driving the impeller within the patient's body.

摘要： An axial-flow blood pump for pumping blood includes a substantially cylindrical outer enclosure. A tubular housing concentric with and located within the outer enclosure has at one end an inlet and at an opposite end an outlet. A motor stator is concentric with and located between the outer enclosure and the tubular housing. An impeller is concentric with and located within the tubular housing. The impeller is suspended in operation by a combination of passive magnetic forces between magnets within the impeller or magnetized regions of the impeller and the motor stator and hydrodynamic thrust forces generated as blood flows between the tubular housing and a plurality of hydrodynamic thrust bearing surfaces located on the impeller. A volute may be in fluid-tight connection with the outlet of the tubular housing for receiving blood in the axial direction and directing blood in a direction normal to the axial direction. The volute has a flow-improving member extending axially from the volute and into and coaxially with the tubular housing.

摘要： A liquid pressing device includes mainly a power device consisting of a motor with a spindle, an upper cap on the motor and a lower cap under the motor, a shell for containing the power device, a helical device fitted around the spindle of the motor and having a conical body and a plurality of helical leaves around the conical body. The helical leaves spiral down to form a helical groove between every two helical leaves for water to pass through. The helical leaves have thickness gradually becoming thinner and thinner downward, and the helical grooves gradually become narrower and narrower downward to add pressure to water flowing up therein. Then the conical member functions to add second pressure to water passing through, sending it to a very high location. Then the liquid pressing device can function as a water pump or a propeller.

摘要： A delivery unit which is provided for feeding motor-vehicle fuel has an electric motor (1) with vanes (1) arranged on the lateral surface of a rotor (4). During rotation of the rotor (4), the vanes (11) feed the fuel in a pump channel (19) between the rotor (4) and a stator (3). The delivery unit is thus constructed in a particularly compact manner and is cost-effective to produce.

摘要： A blood pump preferably has a magnetically suspended rotor that rotates within a housing. The rotor may rotate about a stator disposed within the housing. Radial magnetic bearings may be defined within the stator and the rotor in order to suspend the rotor. The radial magnetic bearings may be passive magnetic bearings that include permanent magnets disposed within the stator and the rotor or active magnetic bearings. The pump may further include an axial magnetic bearing that may be either a passive or an active magnetic bearing. A motor that drives the rotor may be disposed within the housing in order to more easily dissipate heat generated by the motor. A primary flow path is defined between the rotor and the stator, and a secondary flow path is defined between the stator and the rotor. Preferably, a substantial majority of blood passes through the primary flow path. The secondary flow path is large enough so that it provides adequate flushing of the secondary flow path while being small enough to permit efficient operation of the radial magnet bearings across the secondary flow path.
