Abstract: An inflatable cuff for blood pressure measurement includes a first inflatable bag to press an arterial vessel of a body portion of a living subject for stopping blood flow; a second inflatable bag for sensing a pulse wave propagating along the arterial vessel, which is supported by the inflatable cuff such that the second inflatable bag is located inside a downstream-side portion of the first inflatable bag in the direction of the blood flows; a shielding member disposed between the first inflatable bag and the second inflatable bag so as to prevent an oscillation of the first inflatable bag from propagating to the second inflatable bag; and a slidable separating member disposed between the shielding member and the second inflatable bag so as to prevent generation of a noise caused by a slide contact of the shielding member with the second inflatable bag.

Abstract: A cutting pen with a bar-shaped cutter having a blade portion at one end thereof and a cylindrical holder into which the bar-shaped cutter can be inserted from the other end of the bar-shaped cutter. The holder has a radial bearing disposed corresponding to one end of the bar-shaped cutter and a thrust bearing disposed corresponding to the other end to support the inserted bar-shaped cutter in such a manner as to allow rotation around the axis thereof. The cylindrical holder attracts and holds therein the bar-shaped cutter by magnetic attraction, in such a manner that the work of attaching and/or detaching the bar-shaped cutter can be performed simply and easily in a short time, and the bar-shaped cutter is held firmly preventing it from falling off the cylindrical holder during use of the cutting pen.
