Patent number: 8425579Abstract: The present invention relates to a therapeutic knee brace system including a leg brace for support, a retainer for securing the therapeutic knee brace system to a knee joint therapy site, a brace joint providing a limited range of flexion to the knee brace, and an active thermal exchange bladder coupled to a contrast therapy system for delivering a therapy fluid at a select temperature, pressure and rate. Thermal exchange bladder is removable, and the pressure may be constant or dynamic. The angle of flexion may be selected by the therapy recipient, and the range of flexion of the brace joint is configurable. The knee brace may communicate range and instant angle of flexion of the brace joint to a continuous passive motion (CPM) device, and communication may be mechanical, electronic or wireless. A knee brace coupler attaches to a CPM coupler on the CPM device to selectively couple the therapeutic knee brace system to the CPM device.Type: GrantFiled: October 3, 2006Date of Patent: April 23, 2013Assignee: VitalWear, Inc.Inventors: Howard Edelman, Daqing Liu

Patent number: 8226698Abstract: The present invention relates to a therapeutic cranial wrap for use with a thermal contrast therapy systems and methods for providing a temperature regulated fluid. The cranial wrap includes an active thermal exchange bladder and an active compression bladder, adapted to fit the cranial therapy site. The thermal exchange bladder may be coupled to the thermal contrast therapy system. The compression bladder may compress the therapy site. In some embodiments, the compressive bladder may be integrated into the thermal exchange bladder, or may be omitted. The cranial wrap also includes a contoured shell, known as a hood shaped therapy pad, which is adapted to snugly fit the cranial therapy site and provide neck support. Adjustable straps, including at least one strap that circumvents the cranium, secure the cranial wrap in a fitted position adjacent the therapy site. The cranial wrap couples to the thermal contrast therapy system which includes a hot and cold fluid reservoir, a mixing valve, and a fluid pump.Type: GrantFiled: September 24, 2008Date of Patent: July 24, 2012Assignee: VitalWear, Inc.Inventors: Howard Edelman, Elena Mednikoff, Daqing Liu

Patent number: 8052628Abstract: The present invention relates to a therapeutic spinal column brace system, comprising an active thermal exchange layer for providing thermal contrast therapy to a therapy site, an active compression bladder for providing compression to the therapy site, at least one cushion layer for comfort, a rigid shell including at least one rigid support brace, and an adjustable strapping system to secure the therapeutic spinal column brace system to the spinal column therapy site. In some embodiment an active amalgamated bladder or a thermal exchange and compression bladder may be used in lieu of the thermal exchange bladder and the compression bladder. By regulating the pressure within the bladders the compression may be steady or pulsating to achieve a therapeutic effect. A contrast therapy system comprising a hot reservoir, a cold reservoir, a mixing valve, and a fluid pump for delivering the therapy fluid to the therapeutic spinal column brace system may be utilized.Type: GrantFiled: September 1, 2006Date of Patent: November 8, 2011Assignee: VitalWear, Inc.Inventors: Howard Edelman, Daqing Liu

Patent number: 7694693Abstract: The present invention relates to fluid mixing valves, and more particularly, to mixing valve assemblies which incorporate a ball element and which are adapted for use in a thermal or contrast therapy system, or medical thermal therapy system. The ball element of the present invention is characterized by continuously varying restrictive inlets which enable the user to obtain a substantially linear therapy temperature profile while maintaining substantially constant outlet pressure and flow rates.Type: GrantFiled: November 30, 2005Date of Patent: April 13, 2010Assignee: VitalWear, Inc.Inventors: Howard Edelman, Daqing Liu

Patent number: 7658205Abstract: The fluid coupler comprises a male coupler, a female coupler, and a seal between the male coupler and the female coupler when they are coupled, preventing fluid leakage. The female coupler receives the male coupler when in a coupled position. The male coupler includes a two pieced housing, a unitary valve and a biasing member. The two pieces of the housing may be joined. A cavity runs the length of the housing. The female coupler includes a housing, an annulus, a unitary valve and a biasing member. The annulus and the housing may be joined. A cavity runs the length of the housing. The unitary valves and biasing members fit within the cavities and are capable of longitudinal positioning within a configurable range. When male coupler and female coupler are coupled, the unitary valves are open permitting fluid flow. Otherwise, if uncoupled, the unitary valves are closed preventing fluid leakage.Type: GrantFiled: February 20, 2007Date of Patent: February 9, 2010Assignee: VitalWear, Inc.Inventors: Howard Edelman, Daqing Liu
