A leg support exoskeleton is strapped on as wearable device to support its user during squatting. The exoskeleton includes a knee joint connected to a first line and a second link, which is configured to allow flexion and extension motion between the first link and the second link. A force generator has a first end that is rotatably connected to the first link. A constraining mechanism is connected to the second link and has at least two operational positions. In a first operational position, the second end of the force generator engages the constraining mechanism, where the first link and the second link flex relative to each other. In a second operational position, the second end of the force generator does not engage the constraining mechanism; the first link and the second link are free to flex and extend relative to each other.

The present invention is an apparatus and method for use in a treatment for prevention of arthrofibrosis that includes a first and a second substantially L-shaped frames, each L-shaped frame having a first member and a second member extending from the first member in a substantially perpendicular direction and terminating in a first end, a fixed plate extending between the first members of the L-shaped frames, the fixed plate being parallel with the first members of the L-shaped frames, a movable plate pivotally coupled to the first ends of the first members of the L-shaped frames with, a pneumatic piston coupled to the movable plate and the fixed plate, a hand operated valve operatively coupled to the pneumatic piston and a goniometer coupled to the movable plate and one of the L-shaped frames, the goniometer adapted and configured to indicate the angle between the movable plate and the fixed plate.

A knee range of motion device utilizing tangential joint translation and distraction is disclosed. The device includes a carriage connected to a base, the carriage having a base attachment section; a thigh support section pivotally attached to the base attachment section; and a lower leg support section pivotally connected to the thigh support section. The device further including a carriage support extending between the thigh support section and the base, the carriage support pivotally connected to the thigh support section and adapted to slide in slots on the base; a first actuator connected to the lower leg support section to extend and retract the lower leg support section, thereby causing a foot support connected to the lower leg section to move; and a second actuator connected to the lower leg support section to raise and lower a calf support, causing an anterior and posterior tibial translation.

A system for dynamically adjusting treatment angle under tension to accommodate variations in spinal morphology during spinal decompression therapy is provided. It provides a tensioning device including a patient-positioning means, a tension-producing actuator, a positioning device, a patient interface device, a control system and a display. The control system with feedback on the resultant tension vector applied to patient spine operationally configured to allow for adjustment of either tension producing actuator position, patient position, or both while applying tension to the patient spine during non-therapeutic tension levels. The control system automatically adjusts tension producing actuator work levels such that the resultant tension vector magnitude remains ideally constant during adjustment of resultant tension vector angle, reducing the risk of eliciting paraspinal muscle contraction due to changes in resultant tension vector magnitude.

A knocking structure of double-head fascia massager is disclosed. The knocking structure includes a motor fixed in a housing of the massager and a rotating shaft driven by the motor. The rotating shaft is arranged on both sides of an axis of the motor. Transmissions are arranged on both sides of the rotating shaft, and pistons are connected with the transmissions. The pistons are constrained to move in two nozzles of the housing. The transmissions drive the two pistons to reciprocate in a staggered manner. Two massage heads are connected to the pistons, and different massage heads reciprocate in a staggered manner. An advantage of the present disclosure is that one motor controls the simultaneous movement of the two massage heads, and two massage heads move back and forth to massage body, which speeds up the frequency of massage and increases the area.

A hip traction device, system, and associated methods are 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 upon receiving a force from a tensioner 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 either removably attachable or permanently attached to the carrier and configured to securely attach to a lower portion of a leg, such that the portion of the leg moves with the carrier during operation of the tensioner.

A device for moving a lower jaw forward includes an upper teeth mounting portion on which upper teeth of a human body are mountable, a lower teeth mounting portion on which lower teeth of the human body are mountable, a sensing portion capable of sensing information which determines a movement time of the lower teeth mounting portion, and a driving portion capable of moving the lower teeth mounting portion relative to the upper teeth mounting portion according to a sensing result of the sensing portion. The driving portion includes a power portion which provides a force for moving the lower teeth mounting portion and a driving connection portion which connects the power portion to the lower teeth mounting portion.

A compression therapy device for vascular diseases and other therapies including a bladder a lever arm acting on the outer surface of the bladder such that cyclical operation of an actuator on the lever arm creates cyclical changes in pneumatic pressure in the therapeutic portion of the bladder.

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.

A smart powered rocking bed is disclosed comprising a plurality of vertical and horizontal actuators in contact with a rocking frame configured to receive the rocking bed, the electronic actuators configured to act together to rock the bed in three dimensions. The smart powered rocking bed also includes a digital processor configured to electrically drive the actuators in a plurality of predetermined multi-directional and simultaneous ocean-like motions over a period of time provided for a user's choice. The smart powered rocking bed additionally includes a linkage configured to connect the rocking frame to the actuators and mechanically provide the multi-directional and simultaneous ocean-like motions in the three dimensions over time as chosen by the user. A smart powered rocking bed system further includes a health care database, a discrete personal digital device such as a cell phone and health care telemetry sensors placed on or in a user thereof.
