  • Patent number: 7794405
    Abstract: A cuff for a blood pressure monitor has an air bag inflated/deflated as the air comes in/out. The air bag has an inner wall portion located on the inner side in the fitted state of the cuff and an outer wall portion located outer than the inner wall portion, and a side wall portion connecting side end portions of the inner and outer wall portions and folded inwards in the deflated state of the air bag to form a gusset at each side end portion of the air bag. A bonded portion is provided at a region of the air bag in its winding direction around the living body, for reducing expansion of the gusset formed by the side wall portion. Thus, occurrence of lateral displacement of the cuff is prevented, and a highly reliable blood pressure monitor of high performance can be obtained.

  • Publication number: 20100213632
    Abstract: According to the present invention, it is possible to easily manufacture a molded plate of a desired size by laminating an unnecessary, inexpensive resin not used as a product in the width direction of a molded plate and simply separating the unnecessary resin after forming the molded plate. Consequently, it is possible to skip a step of cutting the molded plate in the machine direction thereof. Further, it is also possible to skip a polishing step since the cut surfaces of the molded plate in the machine direction thereof can be smoothed. Still further, by arranging a plurality of resins for disposal, it is possible to effectively use the resins when yielding multiple molded plates from one resin sheet.

  • Publication number: 20090312651
    Abstract: A blood pressure measurement bladder (50) has a predetermined amount of air introduced and sealed therein. A CPU (30) measures in advance the P-V property. The blood pressure measurement bladder (50) is wrapped around a measurement site. By exerting pressure from the outer side to the blood pressure measurement bladder (50), the internal pressure in the blood pressure measurement bladder (50) is increased to exert pressure on the blood vessel. During this process, the cuff pressure in the blood pressure measurement bladder (50) generated by volumetric change of the blood vessel by changing the pressure exerted from the outer side to the blood pressure measurement bladder (50), and the pressure pulse wave data are detected. By adding the cuff compliance property obtained by the P-V property that was measured in advance to the detected data as a correction value of the pressure pulse wave, blood pressure is calculated.
