  • FIG. 12 A cross-sectional view of the fourth embodiment of the blood pressure cuff where the occlusion component supported at the bottom at the upstream side by attaching an occlusion support component;
  • FIG. 13 A cross-sectional view of the fourth embodiment of the blood pressure cuff where the occlusion component is supported by attaching an occlusion support component in a direct contact with the body portion of the subject;

  • FIG. 14B A cross-sectional view of the compliance fluid bag(s) with and without flexible sheet;

  • the measurement is achieved by the cuff with and without a compliance fluid bag (or a compliance enhancer).
  • the measurement is achieved by a flexible force sensor with a 1 cm diameter on 8 points along the axis around which the commercial cuff is wrapped.
  • FIG. 4 provides data with and without a compliance fluid bag.
  • the commercial cuff has an approximate width of 13.5 cm including the textile cover.
  • the data show that at the edges of the cuff, the pressure is low and it is relatively uniform around the center.
  • the pressure value measured from force sensor is scaled to the percentage of the output of the sensor, when 200 mmHg is read from mercury indicator of commercial blood pressure meter.
  • the distance from proximal side to distal side of the compliance fluid bags under the occlusion component 201 must be equal to or larger than the width of occlusion component 201 along said axis.
  • a width of the pulse wave detection component 223 smaller than the width of the occlusion component 201 along the axis around which the cuff is wrapped is appreciated. However, a width of 10% to 50% of occlusion component is preferable.
  • an absorber material between compliance fluid bag and pulse wave detection component can be placed to absorb noise and vibrations transmitted through compliance fluid bag and/or occlusion component to improve the signal to noise ratio.
  • Absorber material can be a plastic sheet, composite, porous material, foam, or an encapsulated fluid.
  • the compliance fluid bags 202 in FIG. 11, 12, and 13 can be encapsulated by a fluid or not. But, an encapsulated compliance fluid bag is preferable to improve the practicality. To improve the compliance further, the incompressible fluids such as liquids or gels are preferable. Although, it is not mentioned in detail, it is possible to use multiple compliance fluid bags under the occlusion component 401-a. In this case, with or without overlaps between compliance fluid bags, it is appreciated that the outermost width, i.e. the distance from proximal side to distal side of the compliance fluid bags under the occlusion component 401-a is equal to or larger than the width of said occlusion component along said axis. By doing this, the influences of hydraulic pressure difference and/or gravitational influences at the upstream and downstream side in a blood pressure cuff due to liquid content in the compliance fluid bags can be reduced to some extent, and blood pressure measurement errors can be decreased.
