Methods are disclosed for measuring the size of body parts treated by a compression therapy device. Either the volume or circumference of the body part may be measured. The methods may include evacuating an inflatable compression sleeve to a known pressure, inserting the body part into the compression sleeve, inflating the sleeve to a pre-set condition, and then measuring one or more inflation related parameters. The pre-set conditions may include a pre-determined pressure, volume, or size of the inflatable cells comprising the sleeve. The inflation related parameters may include the time to fill the cell to a pre-set pressure, the pressure attained after a pre-set time of inflation, or the measured volume of a cell after a pre-set amount of air is introduced into it. The methods may also include deflating the cells from the known inflation state to a second inflation state and measuring similar parameters.

Person support systems, controllers, methods, and computer program products. A computer program product for controlling a person support surface includes program instructions stored thereon that cause a controller to receive an input corresponding to at least one selected sector of the person support surface and a selected air therapy, determine which of a plurality of zones of bladders of the person support surface are located within the selected sector, generate a control schedule that directs an inflation level of each of the zones of bladders within the selected sector based on the selected air therapy, and instruct an air supply and at least one air control box in accordance with the control schedule to adjust an internal air pressure of each of the plurality of bladders independently of one another while providing a different internal air pressure of each remaining bladder located outside the selected sector.

A pressotherapy apparatus including a device for forming a treatment enclosure to be placed around a section of the body. The device has inflatable and deflatable cells having an upper membrane and a lower membrane which are connected together. The cells are supported by an external wall opposite a body surface of the device. The cells are disposed in a stack between two end cells. The cells between the end cells are stacked by overlapping in a position inclined between a high-end near to the external wall and a low end near to the body surface. The cells of the stack have an active portion of the upper membrane extending from the low end not covered by the lower membrane of an adjacent cell above.

A therapeutic massage system is provided. The system is characterized by a controllable compressed air delivery system and a cushion adapted for operative union with a portion of the air delivery system. The cushion includes a support pad and a therapy pad, the support pad having head and vertebral column supporting portions. The support pad vertebral column supporting portion is characterized by longitudinally extending compartments containing filler material. A central compartment of compartments of the support vertebral column supporting portion having a primary region traversing an axial centerline of said cushion and secondary regions spaced apart from said primary central region. The therapy pad overlays and is affixed to the vertebral column supporting portion of the support pad, the therapy pad including a plurality of fluid fillable channels for receiving a vertebral column wherein select fluid fillable channels of the plurality of fluid fillable channels of the therapy pad are fillable via programmed actuation of an actuatable element of the air delivery system. Filler material of the compartments of the support vertebral column supporting portion are responsive to receipt of body weight upon the cushion and select filling of the plurality of fluid fillable channels of the therapy pad, filler material of the regions of the central compartment being passable throughout segments of same in response to receipt of body weight upon the cushion and select filling of the plurality of fluid fillable channels of the therapy pad.

Techniques and devices for extending a piston, for example connected to a medical device such as a mechanical CPR device, to accommodate different sized patients, are described herein. In some cases, a piston of a mechanical CPR device may include an inner piston at least partially slidable into an external piston sleeve. In one aspect, an external piston spacer may be attached to an outward surface of the inner piston to extend the length of the piston. In another aspect an internal bayonet sleeve may contact one or more locking rods at various positions, enabling adjustment of the length of the inner piston. In yet another aspect, a piston adapter may be removably attached to the end of the piston. In all aspects, the change in length of the piston may be detected and used to modify movement of the piston, for example to more safely perform mechanical CPR.

The present disclosure relates to an assisted exoskeleton rehabilitation device, comprising: a back structure comprising a back crossbeam, a back supporting panel with an adjustable length, and a shoulder pneumatic muscle element mounted on the back supporting panel; an arm structure; a shoulder joint assembly, by which the arm structure is connected to an upper end of the back structure; and a waist structure. An upper end of the back supporting panel is fixedly connected to the back crossbeam, and a lower end thereof is fixedly connected to the waist structure. The shoulder joint assembly comprises a curved shoulder joint connecting panel, a shoulder traction wheel, a shoulder traction line, a first hinge mechanism and a second hinge mechanism. One end of the shoulder joint connecting panel is connected to the upper end of the arm structure by the first hinge mechanism to form a bend-stretch revolute pair of the shoulder joint, and the other end of the shoulder joint connecting panel is connected to the back crossbeam by the second hinge mechanism to form an abduction-adduction revolute pair and a medial rotation-lateral rotation revolute pair of the shoulder joint assembly, and the shoulder traction wheel is fixed to the upper end of the arm structure. The shoulder traction line is connected at one end to the shoulder traction wheel, and connected to the shoulder pneumatic muscle element at the other end.
