The negative pressure generator includes a chamber body with a suction nozzle; a piston, arranged inside the chamber body; and a driving device configured to drive the piston to reciprocated move inside the chamber body so as to generate negative pressure at the suction nozzle.

Provided is a limb compression and circulation apparatus in which, due to a small and light body and a rechargeable power supply device, the limb compression and circulation apparatus is usable regardless of place while being worn and used by a user who is moving. The limb compression and circulation apparatus may include a first air hose connected to one end of an air pressurization portion to send air generated by the air pressurization portion and a plurality of second air hoses connected to the other end of the first air hose and allowing the air generated by the air pressurization portion to diverge and to blow into an air cuff so as to perform effective air divergence. The limb compression and circulation apparatus may prevent air leakage by coupling an air inlet/outlet hole of a second adaptor with an air hose to communicate with each other.

An orthopaedic device includes an upper exoskeleton (2, 4) and a lower exoskeleton (6), and a receiving actuator having a pivot-connection member (10). The exoskeleton is hinged with respect to one another via the pivot-connection member. A receiving transmission device (30) is designed to be able to transmit a movement to the pivot-connection member. At least a first hydraulic cylinder (20) is coupled to the receiving transmission device so as to be able to rotate said pivot-connection member. An emitting actuator has at least a first hydraulic emitting cylinder (51, 55), an emitting transmission device (60), and a motor device (70) coupled to the emitting transmission device. At least one pressurized-fluid-guiding line (42, 45) is designed to allow a hydraulic transmission of movement from the first emitting cylinder to the receiving actuator.

An adjustable knee ankle foot orthosis for unloading weight from a knee joint afflicted with osteoarthritis, thus reducing pain and improving mobility, comprising: an upper and lower frame connected by an unloading hinge assembly, optionally comprising a sensor and processor allowing for remote or automatic control of brace tension. In embodiments, the brace includes a user mechanism that is capable of adjusting a tensioning element while the brace is being worn. In other embodiments, electronic motors, sensors, and indicators may be included in the brace to improve brace performance and user interaction.

This disclosure relates to improved massage chairs that include air cell apparatuses. A massage chair can include at least one air cell apparatus, which can be integrated into a shoulder portion, leg rest portion, arm portion, and/or other portion of the massage chair. An inflatable air bladder can be connected to each air cell apparatus. Each air cell apparatus can transition between a retracted position and an extended position. The air cell bladder can be configured to inflate when the air cell apparatus is in the extended position, thereby securing an individual to the massage chair. Various assemblies can be used to transition the air cell apparatus between the retracted and extended positions. Other embodiments are disclosed.

A system for controlling blood pressure includes a wearable interface having an internal contact surface, the wearable interface configured to at least partially encircle a first portion of a first limb of a subject, a sensing module carried by the wearable interface and configured to determine at least a change in blood pressure of the first limb of the subject, and an energy application module carried by the wearable interface and configured to apply energy of two or more types to the first limb of the subject.

A system is disclosed for stimulating venous and arterial circulation in a patient to prevent deep vein thrombosis, which includes a first inflatable garment sleeve configured to be wrapped around the left calf of the patient and having a first air input tube extending from an exterior surface thereof, a second inflatable garment sleeve configured to be wrapped around the right calf of the patient and having a second air input tube extending from an exterior surface of the second garment sleeve, a portable pump for cyclically inflating the first and second garment sleeves, and a bifurcated tube assembly for connecting the portable pump to the first and second air input tubes of the first and second garment sleeves.

A sexual stimulation system and method including a linear actuator connected by a hose or directly mounted to one of a plurality of sexual stimulation devices such as a “receiver” (for penile stimulation), an inflatable insertable device (for vaginal or anal stimulation), an actuated tube (for penile stimulation), or an actuated insertable device (for vaginal or anal stimulation). The actuator utilizes the displacement of air to drive motion, suction and pressure of the receiver or insertable device in arbitrary or predetermined patterns.

An exoskeleton system comprising at least one actuator unit that includes a fluidic actuator; an exoskeleton device including a fluidic system, and electronics; and a first cable extending from the exoskeleton device to the at least one actuator unit.

A device for physiotherapy includes at least a seating surface and a back rest. The back rest is provided with arm holders positionable under a person's underarms. The back rest is also provided with powered apparatus to move the arm holders in a direction away from the seating surface, thereby to lift a person off the seating surface, and to return the person to the seating surface.
