An enveloping body for at least partly enveloping a limb, comprising an enclosed volume and a connection for supplying fluid to the volume and discharging it from the volume, wherein the enveloping body defines an inner circumference and an outer circumference, wherein the inner circumference of the enveloping body increases as the pressure of the volume increases.

A split-type external device for fixation of cervical and thoracic vertebrae, the device including: a first part adapted to cover a neck and a chest of a patient, a second part adapted to cover a head of the patient, and a third part adapted to cover an abdomen and waist of the patient. The first part includes a first left part and a first right part. The first left part and the first right part are symmetrically disposed along a front middle seam and a back middle seam which are corresponding to axial lines on the front and back of the patient; the first left part includes a left neck part, a left upper chest part, a left front part, a left back part, and a left upper back part which are integrated with one another to yield a first left cavity adapted to accommodating filler slurry.

A device (100) includes a leg engaging section (101) and a foot engaging section (102) intersecting at a heel receiver (103). The leg engaging section and the foot engaging section define a leg insertion aperture (104). A compressible cushion layer (402) is disposed at least in the leg engaging section. At least one bolster tube (401) is disposed interior the leg engaging section. The bolster tube (401) can be selectively removable through one or more apertures (1105,1106).

A fabric-based soft actuator includes a first fabric layer, a second (material) layer, a bladder, and a fluid pump. The first fabric layer has anisotropic or isotropic stretch properties. The second layer is a fabric layer with anisotropic or isotropic stretch properties and/or a strain-limiting layer. The bladder is disposed between or integrated with the first fabric layer and the second layer, while the fluid pump is in fluid communication with and configured to inflate the bladder.

Systems, methods, and devices are described for providing a brace having an inflation control. The control directs fluid flow from an inflation component to one or more inflatable cells of the brace. The inflatable cells are independently inflated and deflated by the inflation component through the control. The control allows a user to create a fluid path between the inflation component and one of the inflatable cells by positioning the control in an orientation corresponding to the desired inflatable cells. Each inflatable cell is independently inflated and deflated in various orientations of the control.

Provided is a neck supporter which is easy to use and which can reliably support the head of the wearer. The neck supporter includes an elongated main body providing said air-bag; an air injection valve that is provided in said main body to enable the air to be injected into said air-bag or discharged therefrom; connection sections (e.g., loops and hooks) that are provided on opposite surfaces in a vicinity of opposite ends of said main body to connect said opposite surfaces to each other; and a plurality of retaining portions (e.g., thermal compression bonding portions and through-holes) that are provided dispersedly as dots in series in a longitudinal direction of said main body to provide bonded portions between a front surface and a back surface of said main body.

A human restraint device enables effective restraint by pressing a person's arms against the person's torso. The device includes a band dimensioned to fit over an upper torso and shoulders of a person; an inflatable tube attached to the band, wherein the tube expands during inflation inwards and away from the band, whereby the tube presses against the torso of the person; a net comprising a mouth attached around a circumference of the band; and a gas release mechanism to rapidly inflate the inflatable tube. Net preferably includes a spit-proof material.

Systems, methods, and devices are described for providing a fluid control for an inflation system. The control directs fluid flow from an inflation component to one or more inflatable cells of the brace. The inflatable cells are independently inflated and deflated by the inflation component through the control. The control allows a user to create a fluid path between the inflation component and one of the inflatable cells by positioning the control in an orientation corresponding to the desired inflatable cells. Each inflatable cell is independently inflated and deflated in various orientations of the control.

A vacuum-molded and reusable limb protecting pad (A) comprises an airtight bag body (10), two locating components (17) being respectively arranged at the positions, which are spaced and correspond to each other, of two inner side surfaces of the airtight bag body (10), the locating components (17) being capable of dividing a containing space (13) in the bag body (10) into a plurality of locating spaces (131), the bag body (10) being maintained to be in a flat and narrow shape, and the adjacent locating spaces (131) being enabled to be spaced, but be communicated with each other for being filled with a plurality of granules (40); an air nozzle (20), the bottom of the air nozzle (20) being sealed on the surface of the bag body (10) in an airtight way, and the air nozzle (20) being internally provided with an air channel (211) which is used for communicating the inside and the outside of the bag body (10) and can be switched into a state of communication or non-communication; a filter screen (112), arranged at a position corresponding to the air channel (221), the sieve number of the filter screen (112) being less than the particle sizes of the granules (40); and at least one tightening component (15), capable of enabling the limb protecting pad (A) to stably surround and cling to the surface of a limb (B).

Wearable devices for spinal deformities, including a wearable brace configured to be worn about a patient's torso, at least one inflation bladder carried directly or indirectly by an inner surface of the brace, and positioned such that inflation of the bladder with a fluid applies a pressure to generate a force on the patient at a targeted location, at least one force sensor carried directly or indirectly by a surface of the brace, to measure the force independent of the bladder, and the force sensor adapted to output a signal indicative of a force applied on the sensor.
