Patent number: 8568489Abstract: The present invention in one embodiment is a vacuum pump including a compressible elastomeric member with an internal reservoir enclosing a volume of fluid, an outlet port providing fluid communication between the internal reservoir and a fluid sink, and an inlet port providing fluid communication between the internal reservoir and a fluid source. The pump further includes first and second pressure elements coupled to the elastomeric member on opposing sides. At least one of the first and second pressure elements is adapted to apply a longitudinal force along, and a rotational force about, an axis extending through the compressible elastomeric member. Upon the application of a longitudinal compression force to the compressible elastomeric member, fluid flows from the internal reservoir to the fluid sink and upon the application of a longitudinal expansion force, fluid flows from the fluid source to the internal reservoir.Type: GrantFiled: August 1, 2008Date of Patent: October 29, 2013Assignee: Otto Bock Healthcare LPInventors: Robert Edward Finlinson, Douglas E. Rush, Lüder Mosler

Patent number: 8496715Abstract: A connector for fluidly connecting the sealed interior of an artificial limb socket with a pressure source when the connector is mounted to the socket at a hole and an artificial limb including same. The connector includes a flexible elongated tubular section having a lumen, a flange coupled to one end of the elongated tubular section, the flange having a seal surface for sealingly abutting one of the socket wall surfaces around the hole, and a tubular portion adjacent to the flange and extending the lumen from the seal surface of the flange. Tubular portion has at least one section oversized relative to hole which provides a reasonable air-tight seal between the at least one section and an inner surface of the hole or the other of said socket wall surfaces around the hole and distant from the flange, when the tubular portion is received within the hole.Type: GrantFiled: April 22, 2008Date of Patent: July 30, 2013Assignee: Otto Bock Healthcare LPInventors: Glenn M. Street, Luder Mosler, Robert Edward Finlinson, William M. Clover, Jr., Erik Laatsch

Patent number: 7744653Abstract: A vacuum pump having shock absorption and controlled rotation for use in an artificial limb. The pump includes a housing having a first chamber, and a shaft configured to be received by and to reciprocate within the first chamber, the housing and shaft forming a pump chamber. A piston may be coupled to the shaft and positioned within the pump chamber, and intake and exhaust ports are fluidly coupled to the pump chamber. Rotational structure is mounted with respect to the pump to provide controlled rotation of the shaft relative to the housing, and shock absorption structure is included within the pump to provide shock absorption for the shaft. Both a pneumatic spring and a mechanical spring element may be provided for the shock absorption structure. An optional adapter couples the shaft to the pylon of an integral pylon prosthetic foot.Type: GrantFiled: April 22, 2005Date of Patent: June 29, 2010Assignee: Otto Bock HealthCare LPInventors: Douglas E.
