摘要： An automatic sphygmomanometer of this invention is arranged to predict, on the basis of the relationship between cuff pressure and the amplitude of a pulse wave, maximal and minimal blood pressures while the cuff pressure is being increased. This automatic sphygmomanometer is capable of minimizing the discomfort inflicted upon a subject by increasing or reducing the cuff pressure to the neighborhood of a predicted maximal or minimal blood pressure at a relative high rate. Concretely, the pressure in the cuff is increased at a relatively high pressure-increasing rate to a level immediately below the predicted maximal blood pressure and, thereafter, the pressure-increasing rate is reduced to a rate suitable for measurement. The maximal blood pressure is in turn measured. When the minimal blood pressure is to be measured, as soon as the maximal blood pressure has been measured, the cuff pressure is rapidly reduced to a level immediately above the predicted minimal blood pressure and, then, the pressure-reducing rate is reduced. The minimal blood pressure is measured under the condition of this reduced rate. Accordingly, it is possible to minimize the discomfort inflicted upon the subject due to pressure and a lengthy operation. Moreover, this invention eliminates the awkward operation of setting a pressure which is approximately 30 mmHg higher than the expected maximal blood pressure.
摘要翻译：本发明的自动血压计被设置为基于袖带压力与脉搏波幅度之间的关系来预测袖带压力增加时的最大和最小血压。该自动血压计能够通过以相对较高的速率将袖带压力增加或减小到预测的最大或最小血压附近来最小化对受试者造成的不适。具体地说，袖带中的压力以相对较高的增压速率增加到紧接在预测的最高血压之下的水平，然后将增压速率降低到适于测量的速率。依次测量最大血压。当要测量最小血压时，一旦测量到最大血压，袖带压力将迅速降低到高于预测的最小血压的水平，然后降低减压率。在该降低率的条件下测量最小血压。因此，由于压力和长时间的操作，可以最小化对受试者造成的不适。此外，本发明消除了设定比预期的最大血压高约30mmHg的压力的笨拙操作。

摘要： An electronic sphygmomanometer measures blood pressure while deflating or inflating a cuff. Cuff pressurization is constant, irrespective of cuff size, up to about 10 mmHg. When this value is exceeded, supply of air to the cuff is controlled in accordance with the cuff size. The decision regarding the cuff size is made by reading in the size from a designating switch. The cuff pressure sampling period during inflation is made shorter than that during deflation.

摘要： A gas flow valve enables constant venting and is used with a cuff showing a rapid decrease in venting ability at a predetermined value on a boundary within the pressure range which allows measurment of blood pressure. The gas flow valve has a body made of an elastic material and comprising a wedge-shaped portion formed integrally with a mounting base so as to have a flat portion with upper and lower surfaces serving as pressure-responsive surfaces, a linear opening formed at the tip of the wedge-shaped portion, and a passageway communicating with the opening and extending in the longitudinal direction within the mounting base and the tip portion. A thin sheet-like member is twisted and disposed in the passageway so that the tip portion is held by the opening. As a result, the elastic deformation of the gas passageway formed by the gaps in the opening during pressure reduction is promoted by the resiliency of the torsion of the thin sheet-like member. A sphygmomanometer air-feeding/discharging apparatus with the gas flow valve has flexibility for cuffs having various shapes and specifications and enables easy adjustment of the orifice area.
