Abstract: A postural change device used to allow imaging a plurality of postures while changing the posture of a portion to be examined of an object by means of a medical image diagnostic apparatus. The postural change device comprises a head-use balloon and a trunk-use balloon dispersedly arranged in a bag-form mat, and a compressor and a valve body carrying out parallel actions on the two balloons, that is, maximum expansion?medium expansion?complete contraction on the head-use balloon, and complete contraction?medium expansion?maximum expansion on the trunk-use balloon, whereby it is possible to sequentially change the cervical spine of the object from an anteversion posture to a neutral posture to a retroflexed posture.

Abstract: In order to improve its durability, a fluid pressure type actuator is comprises an expansible/contractible body having opposite ends sealed by plug members and expands/contracts when fluid is supplied to and discharged from the body; a wrapping body for wrapping the outer peripheral surface of the expansible/contractible body and having its opposite ends fastened and fixed to the plug members; an inlet/outlet for fluid formed in the plug members; and an auxiliary member for preventing or suppressing local deformation in which the wrapping body expands outward when the fluid is supplied to the expansible/contractible body.

Abstract: Provided is a wearable joint driving device in which a plurality of frame members are attached to a wearing body so as to be in contact with the outer surface of the wearing body. Between the frame members, there is mounted a fluid pressure type actuator. The fluid pressure type actuator has an expansion/contraction member and a net-like covering member covering the outer periphery of the expansion/contraction member. The fluid pressure type actuator undergoes a reduction in length through expansion of the expansion/contraction member to thereby generate a driving force. The frame members have a predetermined level of rigidity.

Abstract: A continuous passive motion device includes a base, a link member connected to the base rotatably about a first rotary shaft, a lower-leg-holding section connected to the link member rotatably about a second rotary shaft, and a driving means for bending/stretching the link member and the lower-leg-holding section. A first positioning section for positioning a hip joint is provided on the base. A second positioning section for positioning a knee joint is provided in the vicinity of the second rotary shaft. The first and second rotary shafts are respectively offset in the same direction from the first and second positioning section.

Abstract: A hydraulic pressure actuator having an inner tube and a mesh sleeve covering the outer periphery of the inner tube and longitudinally extendable by pressure fluid fed into the inner tube, wherein a low friction body formed in an elastic cylindrical body by knitting fine fibers in a circumferential direction without a seam is disposed between the inner tube and the mesh sleeve, and the low friction body contributes to an increase in the life of the hydraulic pressure actuator repeatedly performing extension/retraction motions. The hydraulic pressure actuator is used as an actuator for driving a CPM device which supports the extremity of a human body by ay least one of a plurality of members combined with each other and performs the rehabilitation of the joints of a handicapped by operating the member.
