Abstract

The invention provides a respiratory rate monitoring device and method. The respiratory rate monitoring device comprises a first sensing module, a second sensing module and a third sensing module; the first sensing module obtains a first displacement angle; the second sensing module obtains a second displacement angle; the third sensing module obtains a third displacement angle; a first respiratory frequency is obtained according to the change relation of the third displacement angle along with time; a second respiratory frequency is obtained according to the conversion relation of the oxyhemoglobin saturation and the respiratory frequency; and a third respiratory frequency is obtained based on the first respiratory frequency and the second respiratory frequency by adopting a Kalman filtering data fusion algorithm. According to the respiratory frequency monitoring device and method provided by the technical schemes, the respiratory frequency monitoring device is small in size and can be portable and worn anytime and anywhere, achieves remote monitoring and facilitates daily respiratory frequency monitoring of a patient; and the Kalman filtering data fusion algorithm is adopted to process the first respiratory frequency and the second respiratory frequency, so that the respiratory frequency monitoring accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a respiratory frequency monitoring device and method. Background technique [0002] Respiratory rate is a vital sign that monitors disease progression. Abnormal respiratory rate is an important sign of severe disease. To maintain the quality of life of patients with respiratory disorders and prevent disease progression, long-term disease management is required, mainly including adherence to prescribed drug regimens and avoidance of triggers for respiratory symptoms. For example, in asthmatic patients, when symptoms such as "asthmatic wheezing" appear in breath sounds, it indicates a low level of control of chronic diseases. Respiratory frequency monitoring plays a vital role in monitoring and preventing related diseases. However, traditional respiratory rate monitoring methods are limited to fixed-point instrument monitoring in hospitals or wards. round-the-clo...
