Publication number: 20190008663Abstract: A prosthesis socket vacuum device includes a base formed with a first chamber formed with a discharge channel and a vacuum relief channel and a second chamber provided, on an underside thereof, with a locking assembly, which includes a position-constraining block. A positioning assembly having sealing gaskets fit thereto includes a locking pin extending through a positioning member and formed with a recess. In setting the positioning assembly into the base, the positioning member compresses and expels internal air of the first chamber to the outside through the discharge channel in a soundless manner to form a vacuum condition. The locking pin drives the locking assembly to displace until the recess and a closure hole are fixed relative to each other so as to have the locking assembly closes the vacuum relief channel. A gap is provided between the closure hole and the recess to provide an effect of cushioning.Type: ApplicationFiled: July 5, 2017Publication date: January 10, 2019Inventors: Chia-Pao CHENG, Fu-Kuo WU, Hsiang-Ming Wu

Patent number: 10123887Abstract: A vacuum suction and pressure regulation cylinder includes a pneumatic cylinder, in which a fixed division plate is arranged. A piston assembly is slidably arranged in the fixed division plate and includes an airtight piston mounted to a middle portion thereof and including a flowrate regulation screw and an end of the piston assembly is provided with a second airtight piston so as to define, in an interior space of the pneumatic cylinder, a first air chamber, a second air chamber, and a third air chamber, which are in communication with a prosthesis sleeve. When the piston assembly moves, air flow induced in the pneumatic cylinder varies the sizes of the air chambers for regulation of the spaces thereof. Further, the variation of the air chambers helps evacuate the sleeve so as to make a stump and the prosthesis tightly coupled to each other through suction.Type: GrantFiled: December 16, 2016Date of Patent: November 13, 2018Assignee: KEN DALL ENTERPRISE CO., LTD.Inventors: Chia-Pao Cheng, Chih-Hsuan Liang

Patent number: 10028844Abstract: The hydraulic ankle joint includes a main member having a fluid supply chamber storing a hydraulic fluid, a first pressure regulating chamber, a second pressure regulating chamber, and a space connecting the chambers. The space houses an axle element rotatably joined to the main member. The main member is rotatably mounted on a U-shaped hinge seat. An extension piece is extended radially from the circumference of the axle element. A fluid block penetrates through the main member and into the space. The extension piece and the fluid block jointly partition the space into a front chamber and a back chamber. The first and second pressure regulating chambers adjust the back and front chambers' pressure so that impact from walking may be effectively buffered. The fluid supply chamber automatically refills hydraulic fluid into the front and back chambers so as to reduce user maintenance overhead.Type: GrantFiled: December 27, 2016Date of Patent: July 24, 2018Assignee: KEN DALL ENTERPRISE CO., LTD.Inventors: Chia-Pao Cheng, Fu-Kuo Wu, Hsiang-Ming Wu
