Description

  The present invention relates to a sphygmomanometer in which an arm band to be inserted into an upper arm has a predetermined shape in advance, and it is not necessary to wrap an arm band around the upper arm of a person to be measured, and blood pressure can be measured with either the left or right upper arm.

  Conventionally, an arm insertion type sphygmomanometer installed in a hospital or the like inserts the upper arm of one of the persons to be measured (for example, the non-dominant arm) into an opening formed by an arm band, and the measurement start switch with the other hand The blood pressure is measured by operating the operation unit. However, if the other arm is inconvenient, operation becomes extremely difficult.

In addition, there is a blood pressure monitor of a type in which an arm band is wound, in which the arm band and the blood pressure monitor main body are separated and independent (see, for example, Patent Documents 1 and 2). In addition, a sphygmomanometer including an air tank has been proposed (see, for example, Patent Document 3).
