<;P>;PROBLEM TO BE SOLVED: To provide a hemodynamometer for measuring a blood pressure value, and at the same time, correctly detecting the state of air in a measurement environment. <;P>;SOLUTION: The hemodynamometer includes: a body case 21; a pump 41; and a temperature sensor 31. The pump 41 is stored in the body case 21, so as to introduce the air to be supplied to a cuff from the external part of the body case 21 to the internal part. The temperature sensor 31 is stored in the body case 21, so as to detect the temperature of the air. The temperature sensor 31 is arranged on the route of a flow of the air to be introduced to the internal part of the body case 21 by the pump 41. <;P>;COPYRIGHT: (C)2010,JPO&INPIT
