Disclosed is a portable blood pressure measuring device capable of conveniently measuring blood pressure by being continuously worn on the wrist, precisely measuring blood pressure even while having a very simple structure since there are no additional parts such as a cuff or a pump or the like, and transmitting a measured value through wireless communication such that the measured value can be utilized to efficiently manage a users blood pressure. To this end, the present invention provides a watch-type blood pressure monitor capable of being continuously worn on the wrist of a subject, comprising: a blood pressure monitor main body which includes a blood pressure measurement display unit for displaying the measured blood pressure of the subject a band which is combined to the blood pressure measurement display unit and wraps around the wrist an air chamber which is provided on one side of the band, and which has air accommodated therein so as to pressurize a surface of the skin on the wrist and a pressure sensor which is provided to measure the blood pressure from a radial artery during the pressurization of the air chamber. According to the present invention, the blood pressure monitor can be continuously worn like a watch such that it is possible to conveniently measure blood pressure whenever the need arises, and blood pressure can be precisely measured even while having a simple structure since an additional pump is not required.Linvention concerne un dispositif de mesure de pression sanguine portable apte à mesurer de façon commode la pression sanguine en étant porté de façon continue sur le poignet, à mesurer avec précision la pression sanguine tout en ayant une structure très simple étant donné quil ny a pas de parties supplémentaires, telles quun brassard ou une pompe ou analogue, et à transmettre une valeur mesurée par lintermédiaire dune communication sans fil de telle sorte que la valeur mesurée peut être utilisée pour gérer efficacement la pression san
