A vibration appliance includes a vibration-isolation structure which substantially reduces vibration felt by the user at the handle. The vibration motor is mounted to a vibration plate which carries the massage node. The vibration plate floats within the vibration appliance housing, being suspended by a flexible, elastomer membrane having contours such as curves or folds in it that provide freedom of movement of the vibration plate relative to the housing to which the flexible membrane is mounted. This arrangement can be thought of as the motor and vibration node being mounted on a flexible diaphragm that can move freely as if mounted to the housing by a bellows-like arrangement.

A guide device providing a dimensional and ornamental guide that, engaging a leg of an ambulatory assist device used by a person, provides walking assistance, comprising a boot leg or sleeve for joining about a portion of the leg of the ambulatory assist device and receiving a resilient body axially for dimensional extents and receiving a guide member having a bottom glide surface for contact with a floor surface. A method of facilitating guidance of an ambulatory assist device is disclosed.

An elevation device used in the performance of cardiopulmonary resuscitation (CPR) includes a base and an upper support pivotably coupled to the base. The upper support is configured to elevate the individual's upper back, shoulders and head when pivoted. The upper support is expandable lengthwise. The upper support includes a neck support that is configured to support the individual's spine in a region of the individual's C7 and C8 vertebrae throughout elevation of the upper back, shoulders and head.

Improved automatic chest compression systems which use constricting belts, repeatedly inflating bladders, or reciprocating pistons to compress the chest. A bladder is placed between the chest and the particular mechanism used to compress the chest during CPR. The bladder maximizes the effectiveness of chest compressions.

A detachable and interchangeable hand-and-foot massager for separate use includes a main body and a massager, the massager includes a hand massager and a foot massager. The hand massager or the foot massager is detachably mounted on the main body. The main body includes an upper cover of the main body, a base of the main body, an inflation and deflation device, and a massage device for hands and foot. The upper cover of the main body is buckled on the base of the main body, and the upper cover of the main body is provided with an embedded slot. The hand massager or the foot massager includes a massager upper cover, a massager bottom cover and an airbag assembly. The massager bottom cover is provided with a block, and the connector is fixedly mounted in the block. The main body and the massager can freely disassembled and combined.

A body lightening system for at least partially supporting the weight of a user, the system including a structure having a frame and a motion system, the motion system driving the structure to follow the movements of the user, a holding system, the holding system including a holding mechanism, a hanger and a plurality of hanging cables, the plurality of hanging cables connecting the hanger to a harness to be worn by the user, a power system including a power source for powering the body lightening system, and a human machine interface, the human machine interface providing control over the motion of the motion system and the percentage of the user's weight supported by the holding system.

This invention pertains to advanced medical walker that provides tremendous safety to the users of the medical walker. The novelty introduced here is the addition of the foldable seat pads and safety legs to the medical walker to protect the user from falling down in an uncontrollable situation or fatigue condition, wherein falling down and its resulting traumatic injuries is a serious concern for the users who are in the low-energy state, or are without the accompany of a caring attendance. This invention addresses this concern. There is a wide variety of operation for this invention; this walker can be used in any private or public place such as private homes, hospitals, nursing homes, medical care centers, and alike.

A walking assistance apparatus includes stimulus applying means for applying a stimulus to a leg part on which a walking assistance apparatus is mounted and state detection means for detecting a supporting leg condition and a lifted leg condition of the leg part on which the walking assistance apparatus is mounted. The stimulus applying means applies a first stimulus to the leg part when the state detection means has detected that the leg part on which the walking assistance apparatus is mounted is in the lifted leg condition, and the stimulus applying means does not apply a stimulus to the leg part or applies a second stimulus that is weaker than the first stimulus when the state detection means has detected that the leg part on which the walking assistance apparatus is mounted is in the supporting leg condition.

A planar torsion spring has outer and inner hubs connected by a set of beams that are capable of bending to provide torsional compliance when the outer hub is rotated with respect to the inner hub. Each beam is fixed to the outer hub at one end and is attached to the inner hub at its other end by a pin and slot. Slots may be curved. The spring is capable of deflecting to ±

[00001]$\frac{\pi }{6}$

radians and providing 100 N.Math.m of torque. Bearings may be located at the interface between each pin and slot. Beams may have variable width. In a method of fabrication, the design dimensions, material, and slot geometry of the planar torsion spring can be parameterized to design springs that meet specific requirements for different applications. In addition to quantifying performance, the models provide the foundation for further weight, efficiency, and performance optimization.

Described here are devices, systems, and methods for treating one or more conditions (such as dry eye) or improving ocular health by providing stimulation to nasal or sinus tissue. Generally, the devices may be handheld or implantable. In some variations, the handheld devices may have a stimulator body and a stimulator probe having one or more nasal insertion prongs. When the devices and systems are used to treat dry eye, nasal or sinus tissue may be stimulated to increase tear production, reduce the symptoms of dry eye, and/or improve ocular surface health.
