Publication number: 20210315722Abstract: A joint orthosis assembly includes a web, an arm unit, a strap unit, and at least one fastening subassembly. The web has three web portions for being wrapped on an upper limb structure, a lower limb structure, and a joint between the upper and lower limb structures, respectively. The arm unit is retained on the web and includes two arms which are pivotally connected, and which are for being disposed at lateral sides of the upper and lower limb structures, respectively. The strap unit includes two straps each being wound about the web to be coupled between the two arms. The fastening subassembly is configured to permit an end of at least one of the straps to be turnably coupled to a corresponding one of arms.Type: ApplicationFiled: August 3, 2020Publication date: October 14, 2021Applicants: Plus Meditech Co., Ltd., OPPO MEDICAL INC.Inventors: Yueh-Hua Chiang, Kuo-Wei Lee, Ming-Jhih Wu, Rene Winfried Schiller

Patent number: 9889036Abstract: A joint orthosis includes upper and lower members, and a joint mechanism. The joint mechanism includes a shielding cover and at least one of modular front and rear inserts. Each of the modular front and rear inserts is disposed to limit movement of a joint of a human body in a flexion/extension direction. The shielding cover is removably attached to a mounting frame of the joint mechanism and is configured to conceal and prevent access to the at least one or the modular front and rear inserts.Type: GrantFiled: March 31, 2015Date of Patent: February 13, 2018Assignee: Plus Meditech Co., Ltd.Inventors: Yueh-Hua Chiang, Fu-Lin Chuang, Chien-Min Fang

Patent number: 9433045Abstract: A drive circuit with an external mode-adjusting pin includes an operational mode control circuit and a drive processing circuit. The operational mode control circuit further includes a current mirror circuit, a resistor, a capacitor and a comparator. The first comparator input port receives a reference voltage. The second comparator input port couples the second output port of the current mirror and the capacitor. The current mirror circuit bases on a resistor current to generate a charge current for charging the capacitor. As the charge voltage at the second comparator input port reaches a reference voltage, a trigger signal is outputted to the drive processing circuit for controlling the switches thereof. The external pin is defined to one end of the resistor or the capacitor for varying the resistance or the capacitance respectively to determine the operational mode for the driven circuit.Type: GrantFiled: January 16, 2015Date of Patent: August 30, 2016Assignee: Taiwan Semiconductor Co., Ltd.Inventor: Yueh-Hua Chiang

Patent number: 9398971Abstract: A hinge for an orthopedic brace includes: a pivot shaft; a lower leg plate pivoted to the pivot shaft; an upper leg plate; a catch plate having a toothed peripheral edge; and two position adjusting units, each of which includes a rotatable limiting seat, a limiting pin, and a slider body. The rotatable limiting seat defines a housing chamber therein, and is formed with a wall slot. The slider body is slidably disposed in the housing chamber. The limiting pin extends from the slider body through the wall slot for engaging and disengaging the toothed peripheral edge. The catch plate is formed with a guiding groove. The rotatable limiting seat has a tongue protruding into the guiding groove.Type: GrantFiled: March 12, 2014Date of Patent: July 26, 2016Assignee: Plus Meditech Co., Ltd.Inventors: Yueh-Hua Chiang, Fu-Lin Chuang

Patent number: 9351542Abstract: A buckle assembly includes female and male buckle plates. The female buckle plate is formed with an insertion slot defined by a slot-defining wall having first and second wall faces, and has first and second corners. The first and second corners oppose each other, and are different in height with respect to a reference plane. The male buckle plate has a bent end portion that has upper and lower segments and a middle segment cooperating with the upper and lower segments to define upper and lower corners. The bent end portion is pivotable to the first corner by abutting the upper corner against the first corner, such that the bent end portion is rotatable relative to the first corner.Type: GrantFiled: March 5, 2014Date of Patent: May 31, 2016Assignee: PLUS MEDITECH CO., LTD.Inventors: Yueh-Hua Chiang, Fu-Lin Chuang
