A puncture assistance system provides information on a collapse state of a blood vessel to be punctured, caused by pressing action of an ultrasonic probe, when ultrasonic images of the blood vessel are acquired. A puncture assistance systemincludes: vascular diameter detecting meansfor detecting a vascular diameter during acquisition of the ultrasonic images from an ultrasonic diagnostic device; puncture assistance information generating meansfor generating puncture assistance information for determination of whether or not puncture is allowed to be performed based on a collapse state of a blood vessel B caused by pressing action of an ultrasonic probeagainst skin S by comparing a current vascular diameter detected by the vascular diameter detecting meanswith a standard vascular diameter stored in advance; and a monitorthat presents the puncture assistance information.

In a long member bending apparatus having a bending head and a material supply unit, the bending head is composed of a base plate having a guide pipe, which includes a guide hole for passing a long member, at the center thereof, a movable plate having a die, which applies a bending force to the long member supplied from the guide pipe forward, disposed at the center thereof, and six extendable units including hydraulic cylinders interposed between the base plate and the movable plate and universal joints disposed to both the ends of each hydraulic cylinder, thereby a parallel link mechanism is arranged that executes a motion of a total of six degrees of freedom including three degrees of freedom of translational movement and three degrees of freedom of rotation by expanding and contracting the hydraulic cylinders to set the position (distance, offset), inclination, and the like of the movable plate with respect to the base plate. With this arrangement, there can be provided a long member bending apparatus having a simple structure capable of bending a pipe member, a bar member, a strip member that has an asymmetric cross section, and the like.
