A pressure controller for a fluidic bladder has in sequence a pump, a first fluid line, a supply pressure sensor, a second fluid line, a bladder having an inlet coupled to the second fluid line, a bladder outlet coupled to a third fluid line of substantially equal length to the second fluid line, a return pressure sensor, and a fourth fluid line coupled to the return pressure sensor and returning fluid from the pump to the reservoir. A pressure estimate is formed by averaging the supply pressure and return pressure. The pressure controller receives a setpoint pressure as a command and data over a wireless channel, and computes a head pressure offset by turning the pump off and measuring the supply and return pressures.

Embodiments of the invention are directed to devices and methods for providing extension and flexion assistance. A device manipulates a foot of a user, thereby providing extension or flexion assistance to an ankle of the user, and includes a footplate positioned at a pre-determined distance from the user and adapted to pivot about an axis defined by the ankle as the foot extends or flexes about the ankle; and a force application system comprising a force applicator connected to the footplate, and a force application mechanism, wherein the force application mechanism is configured to apply a force to the force applicator, thereby providing the extension or flexion assistance to the foot about the ankle.

A BFRT cuff and portable electric pump system and a method for exercising using said cuff. The method incudes providing a BFRT cuff and a portable electric pump system, placing the BFRT cuff on a limb of a user, connecting the BFRT cuff to the portable electric pump system, selecting a pressure value or percent of limb occlusion pressure (LOP), causing the portable electric pump system to supply air to the BFRT cuff until the LOP of said limb is obtained, terminating air flow to the BFRT cuff and then reducing the pressure in the BFRT cuff, disconnecting the BFRT cuff from the portable electric pump system, and exercising the limb of the user while the BFRT cuff is at a selected pressure or a selected percent of LOP.

Stimulation devices are disclosed. An example apparatus includes a housing including a chamber. The housing defines an opening to the chamber. The example apparatus includes a flexible material protruding from the opening and configured to sealingly engage a portion of a body of a user including a clitoris. The example apparatus includes a drive unit disposed in the housing. The drive unit is to cause a volume of the chamber to alternate between a first volume and a second volume, the alternating volume of the chamber to cause pressure in the chamber to modulate between positive pressures relative to an ambient pressure and negative pressures relative to the ambient pressure. The modulated positive pressures and negative pressures are to be applied to the portion of the body via the opening.

A system for adjusting pressure locally acting on the skin including a set of adjacent modules distributed so as to form a layer each module includes a cushion capable of changing shape and comprising a cavity, a valve, a tank, and a pressure sensor, wherein the cavity and the tank are in communication with each other by means of the valve, and the sensor is placed so as to sense pressure directly or indirectly acting on the cushion and a feedback loop arranged such as to increase or decrease the change in the shape of the cushion on the basis of the pressure detected by the sensor.

An example stimulation device includes a housing, a longitudinal axis of the housing being an axis of longest extension along a length of the housing from a first end to a second end of the housing, a first portion of the housing defining an opening to a chamber, a central longitudinal axis of the first portion of the housing extending through the opening, the central longitudinal axis of the first portion of the housing disposed at a non-perpendicular angle relative to the longitudinal axis of the housing; and a drive unit disposed in the housing, the drive unit to cause a volume of the chamber to change to cause pressure in the chamber to alternate between positive pressures and negative pressures relative to an ambient pressure, the alternating positive and negative pressures to be applied to a portion of a body of a user including a clitoris via the opening.

Provided is a spinal traction device and a spinal traction method for spinal traction, and the spinal traction device includes: an upper body support unit configured to support an upper body of a person and having at least one spine pressing unit installed on one surface thereof; a lower body support unit configured to support a lower body of the person and having a moving means so as to move away from or close to the upper body support unit; and a controller configured to adjust a movement of the lower body support unit. The spinal traction device has a technical feature in which at least one spine pressing unit is in close contact with and supports the spine of the upper body when the lower body support unit moves.

A seat cushion includes a plurality of inflatable cells, a pumping mechanism, and a manifold or valve system fluidly between the pumping mechanism and the inflatable cells. The manifold or the valve system, which may include a clutch and a motor, connect the pumping mechanism with, the inflatable cells such that a plurality of zones are created. A valve assembly can include a plurality of valves and is adjustable among at least three valve configurations to vary fluid connections to the inflatable cells to produce rearwardly advancing waves. The pumping action produced by the inflation and deflation of the inflatable cells assists in pumping blood in a user's legs back toward the heart.

This disclosure includes manipulating apparatuses and related methods. Some manipulating apparatuses include an actuator having a semi-rigid first segment, a semi-rigid second segment, and one or more flexible cells disposed between the first segment and the second segment, where the actuator is configured to be coupled to a fluid source such that the fluid source can communicate fluid to vary internal pressures of the one or more cells, and where each cell is configured such that adjustments of an internal pressure of the cell causes angular displacement of the second segment relative to the first segment.

An adjustable respirator shell, suitable for being worn on a human body trunk, includes a body, a belt and a buffer. The body includes a protrusive portion and a contact portion. The protrusive portion has an opening connecting a fluid pressure controller, and the contact portion is to contact the human body trunk. The belt, connecting the body, is to surround the human body trunk so as to fasten the adjustable respirator shell on the human body trunk. The buffer covers a circumference of the contact portion, and the contact portion contacts the human body trunk via the buffer. In addition, the buffer includes at least one cushion.
