Electronic device, monitoring and feedback system on thoracoabdominal motion and method thereof

Abstract

An electronic device, a monitoring and feedback system on thoracoabdominal motion (TAM) and a method thereof are provided, where the method includes the following steps. TAM signals of a user in a natural state are measured. Next, the TAM signals are decomposed so as to extract main components thereof. Energy of the main component and the non-noise components of the abdominal motion signal are calculated to obtain the abdominal contraction. Instantaneous phases of the main component of TAM signals are calculated to obtain the instantaneous coordination of TAM and the self-ability for adjusting TAM. A TAM mode of the user is evaluated in the natural state according to the abdominal contraction, the instantaneous TAM coordination, and the self-ability for adjusting TAM. The user is further instructed to adjust the TAM state according to a target environment mode.

Description

technical field [0001] The invention relates to a monitoring and feedback system for thoracic and abdominal movements, a method thereof and an electronic device. Background technique [0002] From the definition of the process and mechanism of respiratory movement, "Thoracoabdominal Motion" (Thoracoabdominal Motion, referred to as TAM) refers to changes in the contraction and expansion of the chest cavity and abdomen, and its influencing factors include gender, age, posture, respiratory movement conditions, and symptoms The current state of health of the body, such as state, and external environmental stimuli. In clinical medicine, the respiratory physiological function examination items are used to express the degree of thoracoabdominal asynchrony (TAA) as the performance index of specific respiratory physiological function by the phase angle of chest and abdominal movement. One of the important parameters of postoperative care for related diseases and respiratory organs. ...

AI Technical Summary

Problems solved by technology

[0003] However, even if the measurement process of the thoracic and abdominal motion is performed in a controlled external environment such as a hospital pulmonary function laboratory, the unsteady thorax and abdominal motion presented by the user often leads to the phase angle between the subsequent measurement and calculation. Inaccurate

For example, the user's measurement under unstable conditions such as body shaking and muscle contraction will cause noise with different bandwidths

In addition, most of the existing related systems observe the TAA level in the unit of breathing cycle, unable to observe the instantaneous (instantaneous) changes, and it is difficult to know the instantaneous changes of the user's chest and abdomen movement during breathing

[0004] In order to solve the aforementioned problems and lead to quite different results, the current filtering method is used to suppress noise, but it also causes phase shifts and causes deviations in the TAA phase angle.

At the same time, in terms of clinical application, although there are currently developments and uses of physiological feedback instruments, there is still no effective index for instantaneous TAA, and there is no filter phase difference feedback compensation for the instantaneous coordination process of thoracic and abdominal movements and the corresponding monitoring and construction.
