Abstract:
Methods and systems for dynamic compression of venous tissue enable improved blood movement in the extremities. In accordance with an exemplary embodiment, a pressure pad provides a compressive force to the venous plexus region of the foot. The pressure pad is successively withdrawn and re-pressed against the foot. Improved blood circulation may reduce the occurrence of undesirable complications such as deep vein thrombosis, ulcers, and the like.
Abstract:
The invention is an apparatus for increasing intrathoracic pressure for resuscitating cardiac arrest patients. The apparatus comprises a flexible, substantially inelastic belt wrapped around the patient's chest and attached to a force converter. The force converter converts a downwardly directed force into a chestward resultant, which depresses the sternum, and two belt tightening resultants. The force converter comprises a pair of arm assemblies, each having a pair of spaced arms, which are pivotably mounted to a base. The base is positioned near the patient's sternum and the ends of the belt attach to one end of each arm assembly. The opposite, handle ends of the arm assemblies are depressed toward the chest causing tightening of the belt and compression of the chest cavity.
Abstract:
A resuscitation device for automatic compression of victim's chest using a compression belt which exerts force evenly over the entire thoracic cavity. The belt is constricted and relaxed through a motorized spool assembly which repeatedly tightens the belt and relaxes the belt to provide repeated and rapid chest compression. An assembly includes various resuscitation devices including chest compression devices, defibrillation devices, and airway management devices, along with communications devices and senses with initiate communications with emergency medical personnel automatically upon use of the device.

Abstract:
A hip traction device and associated methods is disclosed. Such a device may include a base having a proximal end and a distal end, a guide coupled to the base, a carrier configured to move along the guide, a tensioner coupled to the base and configured to provide a force to the carrier to move the carrier toward the distal end of the base, causing a leg to be put in tension, and a single body coupling mechanism being removably attached to the carrier and being configured to securely attach to a lower portion of a leg when the body coupling mechanism is detached from the carrier.
Abstract:
A motion assistance device has a biological signal detection means for detecting a biological signal from the wearer of the device; a motion assistance device installation member having a drive source for applying torque acting to the wearer by use of each joint of the wearer as a rotating shaft; a control means for controlling the drive source to generate torque corresponding to the biological signal detected by the biological signal detection mean; a drive torque estimation means for estimating the drive torque generated by the drive source; a joint angle detection means for detecting angular displacement of a joint; and a parameter identification means for substituting the drive torque estimated by the drive torque estimation means and the angular displacement detected by the joint angle detection means into an equation of motion to specify the wearer-specific dynamics parameter, the equation relating to the entire system and including wearer-specific dynamics parameter. The control means controls the drive source according to a predetermined control method, based on the equation of motion into which the dynamics parameter identified by the parameter identification means is substituted.
Abstract:
A massage machine includes a seat portion, a backrest arranged at the rear of the seat portion, and a massage mechanism including a treatment member movable along the backrest in an up-and-down direction and/or in a left-and-right direction. The massage machine further includes a position detection unit for detecting an up-and-down position and/or a left-and-right position of the treatment member, a force detection unit for detecting the force applied from a user to the treatment member, a physique detection unit for detecting the physique of the user, and a control unit for operating the treatment member according to pre-stored treatment data. The control unit is configured to change the up-and-down position and/or the left-and-right position of the treatment member if the force detected by the force detection unit exceeds a threshold value.

Abstract:
A cervical traction device includes a base, a cervical force application member, and a motor operably attached to the cervical force application member. The motor preferably drives the cervical application member through a friction drive system in order to provide a force to a person's cervical vertebrae. The friction drive system provides overload protection to prevent application of excessive traction forces to the patient.
Abstract:
A therapeutic mobilization device is disclosed. The device includes a flexion assembly, a pro/supination assembly and a valgus carrying angle compensation device. The flexion assembly has an arm attachment assembly and an elbow actuator and the elbow actuator defines and axes of rotation. The pro/supination assembly is attached to flexion assembly and has a distal forearm attachment assembly and a pro/supination actuator operably connected thereto. The valgus carrying angle compensation device is operably attached to the flexion assembly and the pro/supination assembly. Preferably the pro/supination assembly is slidably mounted on a housing shaft whereby during flexion the pro/supination assembly is free to move along the housing shaft. Further, preferably the arm attachment assembly includes an attachment ring and an adjustable clamp pivotally attached thereto whereby the attachment ring defines a pro/supination axis and the adjustable clamp pivots orthogonally to the pro/supination axis.
