DEVICES, SYSTEMS, AND METHODS FOR MONITORING BLOOD PRESSURE

摘要

A system and method for measuring a subject's blood pressure is provided. The system includes a sphygmomanometer cuff configured to apply a pressure to a blood vessel region so as to restrict the flow of blood through a blood vessel of the region; at least one transducer configured to transmit a signal toward the region and to detect a return signal indicative of a velocity of blood flow through the blood vessel; and an apparatus having a processor configured to determine a systolic blood pressure of the subject. The processor is configured to determine whether the return signal corresponds to a first Korotkoff sound of the blood flow through the blood vessel, reduce pressure applied via the sphygmomanometer cuff if the return signal does not correspond to the first Korotkoff sound, and determine pressure applied via the sphygmomanometer cuff when the return signal corresponds to the first Korotkoff sound.

1. A system for measuring a subject's blood pressure comprising:
a sphygmomanometer cuff configured to apply a pressure to a blood vessel region so as to restrict the flow of blood through a blood vessel of the blood vessel region; at least one transducer configured to transmit a signal toward the blood vessel region and to detect a return signal indicative of a velocity of blood flow through the blood vessel; and an apparatus comprising a processor configured to:
receive the return signal detected by the transducer,determine whether the return signal corresponds to a first Korotkoff sound of the blood flow through the blood vessel,gradually reduce the pressure applied via the sphygmomanometer cuff in an instance in which the return signal does not correspond to the first Korotkoff sound, anddetermine the pressure applied via the sphygmomanometer cuff in an instance in which the return signal corresponds to the first Korotkoff sound,wherein the pressure determined by the apparatus is a systolic blood pressure of the subject.
