A wearable soft exoskeleton apparatus includes: a fluid supplying portion; and a soft exoskeleton portion which is connected to the fluid supplying portion and is configured to be able to be worn in legs of a user, a soft exoskeleton portion being made of elastic material to simulate motions of the legs and being provided with a fiber conduit through which fluid flows, the soft exoskeleton portion being inflated to support the legs of the user when the fluid is supplied to the fiber conduit from the fluid supplying portion. The soft exoskeleton portion includes: a fiber tube which is formed in a mesh type to be able to enclose a femoral region and a shinbone; and a fiber structure which is disposed within the fiber tube in a structure in which cells of a predetermined shape are connected to one another so as to form a plurality of the fiber conduits therein.

Embodiments provide devices, systems and methods for preventing deep vein (DV) thrombosis (DVT). One embodiment provides a DVT prevention device including a cuff that fits over a patient's knee, an applanator coupled to an inside cuff surface, an expandable member (EM) coupled to the applanator, a pressure source fluidically coupled to the EM and a controller for controlling EM inflation. When the EM is inflated, it applies a force to the applanator which is transmitted to the knee back surface causing a popliteal vein (PV) under the cuff to be compressed so as to increase backpressure behind the compressed PV and subsequently increase the velocity of blood flow in the leg DVs when the EM is deflated. The EM can be inflated in a cycle including pulsed inflation, inflation hold and relaxation. The cycles can be repeated and adjusted to achieve a desired increase of blood flow/velocity in leg DVs.

Disclosed in the present invention is a water circulation pipeline, comprising: an interface pipeline, the interface pipeline comprising a first pipeline and a second pipeline, one of the first pipeline and the second pipeline being provided with water inlets, and the other being provided with a water outlet, the water inlets and the water outlet being used for being connected to a water pool body, the second pipeline being nested in the first pipeline; and a pipeline body having a third pipeline, a first port of the third pipeline being in communication with the first pipeline, and a second port of the third pipeline being in communication with the second pipeline. The present invention can reduce the volumes of the water circulation pipeline and a control box. Also disclosed in the present invention are a control box and a massage water pool.

A Biomimetic implant is an electromechanical implant which mimics the original function of the replaced body part very closely, or surpasses the functions of the replaced body part. The present invention will allow the wearer to artificially inseminate a sexual partner, experience an orgasm as a direct consequence of stroking the shaft of the invention, role play as a male, and serve as a non-surgical penile implant incorporating both aesthetic realism and functionality. Until now, no other dildo or prosthetic has ever existed with the full range of abilities of the invention presented here in. The ability to provide tactile feedback by use of sensors, pass urine, transition from flaccid to erect and also ejaculate make-up four of the most distinct features of the patent presented here in.

The invention relates to an artificial knee joint comprising; an upper part (10) and a lower part (20) which are mounted on one another such that they can pivot about a pivot axis (12); a hydraulic resistance device (30) between the upper part (10) and the lower part (20), which resistance device provides resistance to a pivoting movement, the resistance device (30) having a switching valve (50) in a hydraulic line (37), the switching valve (50) having a valve body which can be displaced in a displacement direction and, in a first position, blocks or partially closes the hydraulic line (37) and, in a second position, releases the hydraulic line (37) and is designed or positioned in such a manner that a pressure force component acting on the valve body (55) perpendicularly to the displacement direction through the hydraulic fluid generates a holding force that counteracts a displacement of the valve body (55), wherein an actuator (60) for exerting a release force is associated with the valve body (55) and moves the valve body (55) from the first to the second position, characterized in that the actuator (60) is coupled to a control device (70) which is connected to a sensor for detecting state data and activates the actuator (60) on the basis of the state data, and the release force is set to be less than the holding force at a predefined pressure force.

An adjustable wheel suspension assembly for a wheeled walker providing both lateral and longitudinal stability under load. With a calibrated spring preload adjustment, the wheel suspension assembly provides lateral stability for any particular user body weight and a wheel deflection working stroke sufficient to absorb wheel shocks over irregular terrain. The wheel suspension assembly is particularly advantageous for upright wheeled walkers.

The present disclosure provides a phallus-like erotic device capable of ejecting a liquid. A body is disposed in a soft sleeve, and an opening is formed at an insertion end of the body. A liquid storage assembly is formed with an inner cavity, and includes a water tube and an air pump. The air pump is connected to the inner cavity. One end of the water tube is disposed on the air pump, and the other end of the water tube is connected to the opening. A control assembly is disposed in the soft sleeve, and configured to control liquid to be ejected through the opening. Due to the liquid storage assembly and the opening at the insertion end of the phallus-like erotic device capable of ejecting a liquid, the control assembly controls the liquid to be ejected, which can simulate real experience of liquid ejecting.

A method for automated CPR includes controlling a position of a compression element during movement of the compression element from an initial starting position (P0) of a first compression cycle to a first compression position (P1) corresponding to a first compression depth and back to a rest position of the compression element. After, the rest position has been reached, the method includes controlling a force exerted on the compression element, to ensure that the compression element stays in contact or re-contacts with the chest while allowing the chest to move upward due to ventilation, prior to the start of a second compression cycle.
