Ultrasound diagnosis apparatus

The present invention provides a portable ultrasound system being superior in operability and design properties, and being allowed to take various storage postures fitting to the volume of a storage place. The keyboard unitprovided with an input device such as a keyboard and the display unitincorporating a display part are mounted on the main body unitthat incorporates a main part of the ultrasound diagnostic system, respectively about the rotation axes Pand P, independently, in such a manner as rotatable, and further the rotation axes Pand Pare on a common axis P. The rotation axis partsupporting the display unitis supported by the bearing of the main body unit in a part lower than the axis P, allowing the display unit to be rotatable about the rotation axis Q that is orthogonal to the axis P. With this configuration, it is possible to take an operating posture that allows the display unitbeing upright to swivel, and multiple storage postures in which the posture of the main body unitwith respect to the keyboard unitand the display unitare variously changed.

Portable ultrasound system

A fluid pressure actuator includes: an actuator body which expands and contracts through supply/discharge of a fluid to generate a driving force; a sensor for detecting a condition of the actuator body; and a control part for controlling a fluid regulator for adjusting a pressure of the fluid supplied to and discharged from the actuator body based on a detection signal from the sensor. The sensor is mounted in the actuator body.

Fluid pressure actuator

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.

Wearable joint driving device

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.
