Description

  The present invention relates to a sphygmomanometer used for measuring the blood pressure of a person to be measured in a home, a medical institution, or the like.

  Conventionally, in this type of sphygmomanometer, an arm band (cuff) containing a fluid bag into which gas or liquid is injected in order to compress an artery located inside the upper arm of the measurement subject is wound around the upper arm surface. The arterial pressure pulse wave generated in the artery is detected by expanding and contracting the fluid bag. As a result, the blood pressure of the measurement subject is measured.

In such a sphygmomanometer, there has been proposed a technique in which the blood pressure is measured by reducing the heart rate by stimulating the senses of vision, hearing, smell, etc. according to the heart rate (see Patent Document 1). .

JP 2007-125336 A

  By the way, when measuring blood pressure with a conventional sphygmomanometer, the blood pressure fluctuates depending on the degree of tension or relaxation, and even within a day, it fluctuates greatly with a slight change, so that the original blood pressure may not be measured. For example, when measuring blood pressure in a hospital, the patient is tense and measured higher than the actual blood pressure, reducing the reliability of the measurement results. Therefore, blood pressure measurement is desired to be performed in a relaxed environment when you feel relaxed.

  In addition, the sphygmomanometer described in Patent Document 1 must also measure the heart rate when measuring blood pressure, and requires another special device. Depending on the heart rate, there are various types such as vision, hearing, and smell. There is a problem that the person being measured is not in a truly relaxing state because a strong stimulus is given.

  Therefore, the present invention has been made in view of the above-described problems, and can produce a relaxed effect on the measurement subject under any environment and improve the reliability of blood pressure measurement. An object is to provide a sphygmomanometer.

  In order to solve the above-mentioned problems, the present invention provides a sphygmomanometer that measures blood pressure based on vibration of an arterial wall due to arterial pulsation accompanying a change in cuff pressure, and is wound around a patient whose blood pressure is to be measured.

A first balloon part that supplies air to the cuff part, and a second balloon part that is formed integrally with the first balloon part and supplies air to the second path. According to the configuration of the present invention, the scent can be generated simultaneously with pressurizing the cuff part, and the operability is improved.

  In the above configuration, the second path has a narrowed portion where the path is narrower than the first path. According to the present invention, air can be efficiently supplied to the cuff portion by providing air resistance to the second path.
