Description

Technical Field

[0001] This utility model relates to the field of medical monitoring technology, specifically to a wearable respiratory monitoring device. Background Technology

[0002] The rhythm, intensity, and frequency of respiratory signals accurately characterize the health status of the respiratory system organs. Respiratory monitoring devices can be used to monitor human respiration. Clinically, it is observed that patients with chronic obstructive pulmonary disease (COPD) experience decreased lung function and reduced respiratory muscle contraction strength; stroke patients experience decreased respiratory muscle strength, diaphragmatic atrophy and thinning, and reduced diaphragmatic mobility; and patients undergoing lung resection for early- to mid-stage lung cancer, resulting in reduced lung volume, surgical trauma, and pain, all of which affect lung ventilation and gas exchange capacity, increasing the risk of pulmonary complications. Deep breathing training promotes maximum lung expansion, allowing previously blocked alveoli to re-ventilate, thereby restoring lung volume, promoting the expulsion of residual gas, preventing alveolar collapse, and improving lung function. It also strengthens diaphragmatic contraction and increases its range of motion, exercising the pectoral and diaphragmatic muscles, helping to promote postoperative cough, improve airway clearance of secretions, and reduce the incidence of complications such as pneumonia and atelectasis. Therefore, deep breathing training has been recommended by the American Thoracic Society and the European Respiratory Society as a pulmonary rehabilitation strategy for individuals with impaired lung function. However, the lack of a convenient and accurate monitoring device to assess the effectiveness of users' deep breathing training is a real problem.

[0003] To address the shortcomings of existing technologies, researchers have conducted long-term research and proposed various solutions. For example, Chinese patent literature discloses a wearable respiratory and body temperature monitoring device [CN202010305045.5], which includes a battery box and a main unit box connected by positioning pins; wearable components connected to both the battery box and the main unit box; a battery and a body temperature sensor module both housed within the battery box; a respiratory sensor component and a main controller housed within the main unit box; and a control circuit board electrically connected to the battery, the body temperature sensor module, and the respiratory sensor component, capable of converting the body temperature signal acquired by the body temperature sensor and the respiratory signal acquired by the respiratory sensor component into corresponding data and sending them to a remote data processing device for processing. This monitoring device is convenient to wear and can simultaneously acquire the user's body temperature and respiratory signals. The control circuit board collects and converts these signals into easily processed data before sending them to a remote data processing device, enabling accurate and timely monitoring of the user's respiratory and body temperature status.

[0004] The above solution has solved the problem of the difficulty of real-time and accurate monitoring of breathing and body temperature by existing technologies to a certain extent. However, the solution still has many shortcomings, such as poor flexibility of breathing monitoring equipment and inability to achieve comprehensive breathing monitoring, which affects accuracy.
