A handheld device for applying mechanical vibration to a body portion of an individual to treat a condition of the individual, includes: a housing; a cantilever beam having a first portion accommodated in the housing, and a second portion that is moveable relative to the housing, wherein the second portion is configured to apply the mechanical vibration to the body portion; and a motor in the housing, the motor configured to oscillate the second portion of the cantilever beam at an oscillation frequency.

Embodiments of the improved stimulation device include a cup and a driver. The cup has a cavity surrounded by a rim. The driver comprises a plate disposed on an underside of the cup, a cam disposed adjacent to the plate, and a motor mechanically coupled to the cam. The driver is configured to intermittently vary a volume of the cavity of the cup from a first volume to a second volume without returning the cup from the second volume to the first volume. In some embodiments, the cup returns from the second volume to the first volume, in between intermittent varying from the first volume to the second volume, due to the resilient nature of the material of the cup and/or the configuration of the cup. This varying of the volume between the first and second volumes creates a pressure field in a chamber formed by the cavity and a user's skin.

A wrist joint actuating structure of a hand rehabilitation device includes a palm orthosis body, a forearm orthosis body and a joint unit. The palm orthosis body includes a plurality of finger support rods and a thumb support rod. The joint unit is a universal joint and is connected between the palm orthosis body and the forearm orthosis body. The palm orthosis body can be turned an angle relative to the forearm orthosis body through actuation of the joint unit according to the bending degree of a user's wrist joint. A tension adjustment unit includes elastic members connected to the finger support rods and the thumb support rod. According to the different stretching tensions required by the fingers or the thumb for rehabilitation, the respective lengths of the other ends of the elastic members to be pressed by a fixing seat are adjustable, so as to adjust different stretching tensions.

The present invention is directed to an autonomous exoskeleton device that includes one or more actuators, one or more controllers, one or more sensors with one or more unidirectional transmissions. The present invention provides a mechanical joint in parallel with a biological joint. The exoskeleton device preferably includes and electric motor and winch, chain, belt, cam transmission or other mechanism for providing unidirectional force to assist rotation about the biologic joint. Moreover, a controller, a motor angle sensor, joint angle sensor and/or force sensor may be used for additional control and monitoring of the device. The motor may be any type of motor, but is preferably brushless in configuration where its diameter is larger than its length to provide a compact and lightweight exoskeleton device.

A method to treat a dry eye condition of an individual, includes: receiving a switch signal generated based on a manipulation of a control switch at a handheld device; and activating a motor in response to the switch signal to oscillate a member at an oscillation frequency, the member having an elongated configuration, and having a portion for placement outside the individual; wherein the oscillation frequency is sufficient to induce tear production when the portion of the member is applied towards a surface of a body portion of the individual.

Embodiments of the present invention relate to an improved stimulation device. Embodiments of the improved stimulation device includes a cup and a driver. The cup has a cavity surrounded by a rim. The driver comprises a plate disposed on an underside of the cup, a cam disposed adjacent to the plate, and a motor mechanically coupled to the cam. The driver comprises a cam pin affixed to the cam, and a bearing rotatably disposed on the cam pin. The bearing is mechanically coupled to a lifter. The lifter is mechanically coupled to a linear bearing, enabling a smooth reciprocating back-and-forth motion from the rotation of the motor. A top of the cup swells and unswells during an operation cycle of the driver.

A massaging apparatus minimizes the application of an excessive load to a massage target area of user's body from a massaging element firmly pressed into contact with the massage target area, provides satisfactory massage treatment, and distributes an excessive load imposed on the massaging element to protect the massaging apparatus itself from damage such as breakage. The massaging apparatus includes a massaging element for performing massage treatment on a massage target area of user's body, and an arm member provided at its head with the massaging element. The arm member has load-reducing mechanism for absorbing a load applied to the arm member from the massaging element. The load-reducing mechanism absorbs a load imposed on the massaging element by exploiting an urgence exerted in a front-rear direction.

Disclosed embodiments provide a massager having at least one expandable chamber. In some embodiments, there is provided an expandable shaft chamber that is inflatable to push a stimulator towards the G-spot of the user to increase contact pressure in that area. This inflation can also allow for a hands-free experience by expanding the width of the shaft inside the vagina for a snug fit tight against the vaginal or rectum walls. In some embodiments, there is provided an expandable ring chamber that is inflatable to securely hold a massager device inside the vagina or rectum, allowing for a hands-free experience.

A massage device includes a coupling member adapted for attachment to a power output shaft, a proximal foam pad attached to the coupling member, and, a distal foam pad bottom. Portions of the distal foam pad are adapted to cover over at least one side of the proximal foam pad and form a highly resilient curved surface. A removable bonnet shaped and sized to tightly fit over the distal foam pad and proximal foam pad includes an outer surface with a low coefficient of friction that may be applied to over the clothing without grabbing for providing a softer and safer percussive massage.

A finger exerciser includes: a frame on which a palm of a subject to be put; a movable section; a first fixing element; and a second fixing element. The movable is configured to move a first finger group of a subject. The first fixing element is configured to fix a position of the first finger group to the movable section. The second fixing element is configured to fix a position of a second finger group to the frame and has a band-like member including at least two attachment parts apart from each other in a longitudinal direction of the band-like member. The band-like member is attached to the frame at the attachment parts and includes a holder whose location to the frame is changeable. The band-like member is configured to hold the second finger group in a state where the band-like member is attached to the frame.
