Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially, and it is a wearable pressure sensor positioning device. BACKGROUND

[0002] In medical monitoring, "heart leveling" usually refers to ensuring that the pressure sensor is at the same level as the heart when monitoring blood pressure, to ensure the accuracy of measurement. This is because the measurement of blood pressure is actually the measurement of the pressure difference between blood pressure and atmospheric pressure, and if the sensor is not at the same level as the heart, the measurement result may be inaccurate due to the influence of gravity. When using an invasive blood pressure sensor, special attention should be paid to the requirement of "heart leveling". This is because if the relative position of the pressure sensor and the heart has a large height difference, the measured pressure value depends not only on the actual blood pressure, but also on the height difference between them, which will cause measurement deviation. For example, if the sensor is higher than the heart level, the measured blood pressure value may be lower; conversely, if the sensor is lower than the heart level, the measured blood pressure value may be higher.

[0030] In the field of medical monitoring, accurate measurement of blood pressure is crucial for assessing the health status of patients.
