A blood pressure measuring instrument

Abstract

The application provides a blood pressure measuring instrument, including: a pulse wave sensing device for sensing the pulse wave of the detected object and outputting a pulse wave signal; a state sensing device for sensing the state of the detected object and outputting state information device; a host, the host includes a signal processing circuit, the signal processing circuit is respectively connected with the pulse wave sensing device and the state sensing device, receives the pulse wave signal output by the pulse wave sensing device and the state information output by the state sensing device, and according to the pulse wave The blood pressure value is calculated from the wave signal, and the blood pressure is monitored and processed according to the state information of the detected object. The blood pressure measuring instrument provided by this application, while obtaining the blood pressure value, also senses the state of the detected object through the state sensing device, and outputs corresponding state information, and monitors the blood pressure according to the state information of the detected object, In order to ensure that the obtained blood pressure value is more accurate and reliable.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a blood pressure measuring instrument. Background technique [0002] At present, non-invasive blood pressure measurement usually uses cuff punching and oscillometric methods to detect non-invasive blood pressure. That is, a pulse wave sensing device is installed inside the cuff, and the sensed pulse wave is transmitted to the main control part of the noninvasive blood pressure measurement device through the airway. The main control part converts the signal into a digital signal through signal acquisition, and then uses a professional algorithm to calculate the blood pressure value. [0003] However, in the process of measuring blood pressure with these traditional sphygmomanometers, the detection of the subject's arm posture and motion is ignored. In actual use, blood pressure measurement has a great relationship with the subject's arm posture and movement. When the ar...

For another example, when the subject is jogging and other sports, the blood pressure value is often measured inaccurately or unreliably due to the interference caused by the movement.

However, traditional sphygmomanometers do not take these scenarios into consideration, especially when medical staff are not on site at home and for long-term monitoring. They treat the measured blood pressure uniformly. Blood pressure or hypotension is obviously unreasonable
