Abstract
A blood pressure measuring apparatus having an inflatable cuff including a first inflatable bag adapted to be worn on a body portion of a living subject so as to exclude blood from an artery located in the body portion, and a second inflatable bag adapted to be worn on the body portion, on a distal side of a middle portion of the first inflatable bag, so as to detect a pulse wave produced from the artery, a first piping which is connected to the first inflatable bag, a second piping which is branched from the first piping and is connected to the second inflatable bag, a pump which supplies an inflating fluid to the first and second inflatable bags via the first and second pipings, respectively, a blood pressure determining device which determines a blood pressure of the subject based on the pulse wave detected through the second inflatable bag when a pressing pressure of the first inflatable bag is changed, and a switching device which is provided in the second piping and which selectively switches the second piping to a connected state in which the second piping is connected to the first piping and to a disconnected state in which the second piping is disconnected from the first piping.
