Multi-purpose physiological treatment tools may include a head covering and coupled to a post. The head may be constructed of at least partially of a polymeric material having a therapeutically effective durometer. The head may have a number of designs and configurations that may be used for treating different body parts and/or body tissues. An example head may have three or more at least partially concaved edges with two surfaces between the edges. Another example head may have two edges with a surface between the edges. Another example head may have a large surface area that is at least partially concaved.

Disclosed is a finger rehabilitation exercise guide apparatus, which is driven through a linear actuator to have a compact layout in an outer surface direction from an operation direction and is configured in such a way that a position of a prismatic joint in an inner surface layout of the operation direction is changeable by a designer, and as necessary, one prismatic joint, one revolute joint, and a link having opposite ends connected with a corresponding prismatic joint and revolute joint are replaced with one pin-in-slot joint while freely changing the position of the prismatic joint, to realize a small number of components and to precisely guide movement of the wearer's finger.

A multi-density, customizable, and interchangeable segmented massage roller that is designed to be adaptable to a user's specific massage needs. The segmented massage roller is comprised of a cylindrical roller core with interior structural supports running the length of the roller core, said roller core being internally threaded at each end, a plurality of exterior ribs running from end to end of the core, a plurality of foam massage rings which include grooves to fit onto the plurality of ribs of the core, wherein each foam massage ring is comprised of a different density, a different massage pattern, and a different height of the massage pattern projections, and two externally threaded hollow retainer caps to connect to and screw into the internal threads at the ends of the roller core. The plurality of foam massage rings are purposely comprised of different foam densities, different massage patterns, and different heights of the massage pattern projections, so that a user may customize the massage roller by interchanging or rearranging the foam massage rings in any combination that the user prefers to deliver the desired massage relief from superficial to deep tissue compression. These features allow the segmented massage roller to be particularly effective at relieving tender and painful conditions such as muscle or connective tissue conditions while allowing it to further be used as an exercise, stretching, and core strengthening apparatus.

Provided is a light irradiated toothbrush, in which light sources, irradiating light having mutually different wavelengths, are arranged in alternation at the bottom of waveguide bristles so that light of different wavelengths give rise to constructive interference which strengthens the intensity of the irradiated light, and the height of the light sources are varied on the basis of the wavelength of the light irradiated therefrom so as to effectively transmit light of short wavelengths to the waveguide bristles, and light having mutually different wavelengths are transmitted by means of the waveguide bristles, thereby effectively transmitting the light to the mouth of a user.

The invention concerns an exoskeleton subassembly comprising: a first exoskeleton part (32), a second exoskeleton part (33), a connecting assembly (60) connecting the first exoskeleton part (32) to the second exoskeleton part (33), the connecting assembly (60) comprising a guide (61) mounted securely relative to one of the first part (32) and the second part (33), and a pin (62) mounted securely relative to the other of the first part (32) and the second part (33), the pin (62) being mounted slidingly inside the guide (61) between a first end position and a second end position, wherein the connecting assembly (60) further comprises a limiting device (64) arranged to allow the pin (62) to rotate relative to the guide (61) when the pin (62) is in the first end position, and to limit the rotation of the pin (62) relative to the guide (61) when the pin (62) is in the second end position, the limiting device (64) comprising a resilient element (65) with which the first exoskeleton part (32) engages when the pin (62) is in the second end position, the resilient element (65) applying an elastic return force on the first exoskeleton part (33) that tends to resist the rotation of the first exoskeleton part (33) and the second exoskeleton part (32) relative to each other.

An adult toy is configured to communicate with a user device of a human user. Receipt of a plurality of input parameters is accumulated via the user device. In response to the accumulation satisfying a preset condition, the accumulation is stopped and a control signal is sent to actuate the adult toy to perform a series of predefined acts. The series of predefined acts are used to sexually stimulate the human user. The control signal includes one or more control sub-patterns, each of the one or more control sub-patterns being configured by each of the plurality of input parameters.

A portable as well as fixed but adjustable automated compression device that applies chest compressions to aid in moving blood to oxygenate the brain and heart and, in some cases, restarting the heart, the lungs, or both, the mechanical chest compression device including a compressor head, a prime mover to drive the compressor head in a reciprocating or oscillating motion, a handle for manual operation, and actuator control to render it hand-holdable and selectively controllable. A stand can be used to support the compression device for hands-free operation.

An exoskeleton may include a pair of actuated limbs rotatably arranged at sides of a lumbar/back frame. A posture restoring assembly may connect the sides of the lumbar/back frame and an upper end of the actuated limbs and return the actuated limbs to an initial or resting position thereof via an elastic or restoring force.

The present disclosure relates to a body massaging device and an operation method thereof, wherein, the body massaging device comprises a support holder detachably mounted on a lower limb of a body; and an anal massaging assembly mounted on the support holder for compressing and/or rubbing an anus of the body as well as perianal skin. The present disclosure provides a support holder to mount the body massaging device at a lower limb of the body and perform a compressing and/or rubbing massage on an anus of the body and a perianal skin by means of an anal massaging assembly mounted on the support holder, so as to stimulate sexually sensitive nerves densely distributed on the anus and the perianal skin, so that a user can obtain a stimulation effect different from the existing penis masturbation appliance or the inserted massaging appliance to stimulate the prostate, when the body massaging device of the present disclosure is used. Moreover, as the body massaging device which is mounted at a lower limb of the body is equivalent to a wearable massaging appliance and does not require a user to hold it for a long time, the user is less prone to fatigue during the use.

Provided is a light irradiated toothbrush, in which light sources, irradiating light having mutually different wavelengths, are arranged in alternation at the bottom of waveguide bristles so that light of different wavelengths give rise to constructive interference which strengthens the intensity of the irridiated light, and the height of the light sources are varied on the basis of the wavelength of the light irradiated therefrom so as to effectively transmit light of short wavelengths to the waveguide bristles, and light having mutually different wavelengths are transmitted by means of the waveguide bristles, thereby effectively transmitting the light to the mouth of a user.
