Abstract
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.
Claims18
An enveloping body for at least partly enveloping a limb, comprising:
- an inner wall and an outer wall that define an enclosed volume;
- elements attached to the inner wall and the outer wall within the enclosed volume to transmit a tensile force;
- a connection for supplying fluid to the enclosed volume and discharging fluid from the volume to change a pressure of the volume;
- and
- a tubular construction having a closed cross-section, an inner circumference, and an outer circumference, wherein the inner circumference of the enveloping body increases as the pressure of the volume increases, wherein the inner circumference of the enveloping body defines a continuous surface that defines the closed cross-section, and wherein the inner circumference is configured to exert a contact pressure on the limb and the contact pressure increases as the pressure of the volume decreases.

An enveloping body for at least partly enveloping a limb, comprising:
- an enclosed volume;
- an inner wall and an outer wall, which enclose the volume;
- a connection for supplying fluid to the enclosed volume and discharging fluid from the volume to change a pressure of the volume;
- a tubular construction having a closed cross-section, an inner circumference, an outer circumference, wherein the inner circumference of the enveloping body increases as the pressure of the volume increases, wherein the inner circumference of the enveloping body defines a continuous surface that defines the closed cross-section, and wherein the inner wall is configured to exert a contact pressure on the limb and the contact pressure increases as the pressure of the volume decreases;
- and
- elements arranged between and connected to the inner wall and the outer wall within the enclosed volume to transmit tensile force, wherein an elongation of the elements is less than an elongation of the inner wall and the outer wall when the pressure of the volume increases.
