摘要: In a rotor for a fluid pump which is made radially compressible and expandable and has a hub and at least one conveying element which has a plurality of struts and at least one membrane which can be spanned between them, provision is made for a design in accordance with the invention which is as simple and inexpensive as possible that at least one first group of struts is pivotable in a pivot plane, starting from a common base, and can thus be spanned open in the manner of a fan, wherein the conveying element lies along the hub and contacts it over its full length in the expanded state to avoid a pressure loss at the margin of the conveying element between it and the hub and thus to realize an optimum efficiency.

摘要: The invention relates to a fluid pump or rotary cutter having at least one first element (9″″, 10′″) which can be brought from a transport state into an operating state by changing at least one mechanical property. Such a pump can, for example, be a blood pump for the medical, microinvasive area. The object of achieving a transition between the transport state and the operating state which is as comfortable as possible and in so doing leaving a freedom in the design of the corresponding apparatus, in particular of a pump, which is as large as possible, is achieved using the means of the invention in that the first element at least partly comprises a material (24, 25, 26, 27) or can be filled with a material or material mixture which passes through a chemical reaction, in particular cross-linking, or a crystallization for transition into the operating state.

摘要: An impeller for use in an aquarium filter pump includes a shaft and a plurality of impeller blades radially extending from the shaft. Each of the impeller blades includes opposite blade faces. A depression is in each of the blade faces and aids in pushing the water. The depression can be a variety of shapes and can have its deepest portion along one of the edges of the blade.

摘要: Apparatus and methods are described including a blood pump that includes an axial shaft, an impeller disposed on the axial shaft, a frame disposed around the impeller, and a motor disposed outside a subject's body, and configured to drive the impeller to pump blood from a distal end of the impeller to a proximal end of the impeller. A drive cable extends from outside the subject's body to the axial shaft, and is configured to impart rotational motion from the motor to the impeller by rotating. The drive cable is held in a preloaded state with respect to the frame, such that initiation of pumping of blood by rotation of the impeller does not cause the drive cable to axially elongate. Other applications are also described.

摘要: An impeller includes a hub and a 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 blood, and 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.

摘要: A fan includes an inlet part disposed to form a fan inlet, a base disposed to form, together with the inlet part, a fan outlet, and a blade. The blade extends from the base to the inlet part, and includes a first guide surface having an inclination toward an outside of the fan in a radial direction of the fan which changes in a direction from the inlet part toward the base, and a second guide surface having an inclination toward the outside of the fan in the radial direction which changes in a direction from the base toward the inlet part.

摘要: A centrifugal fan for use as a blower in a heating, ventilation, air conditioning, and refrigeration (HVACR) system has a plurality of blades each having a leading edge camber angle of at or about 10 degrees to at or about 30 degrees, a trailing edge camber angle of at or about 10 degrees to at or about 30 degrees, a stagger angle of at or about 35 degrees to at or about 55 degrees, and a chord having a length L, wherein the length L over the diameter of the centrifugal fan divided by the diameter D satisfies the inequality 0.25≤L/D≤0.42. The fan blades having these parameters provide improved fan efficiency at certain operating conditions. The fan blades may further have a forward or radial sweep. The fan blades may have a uniform thickness from the leading edge to the trailing edge.
