Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a non-invasive blood pressure measurement device for exercise testing based on photoplethysmogram (PPG). Background Art

[0002] Cardiopulmonary exercise testing refers to monitoring a series of data indicators such as gas metabolism, heart rate, blood pressure, electrocardiogram, etc. of the body under gradually increasing exercise loads, and comprehensively evaluating the overall function and exercise reserve capacity of the body. It is the internationally recognized "gold standard" for evaluating cardiopulmonary function. However, traditional cuff blood pressure monitoring devices lack comfort and convenience, and the medical information obtained is limited, unable to meet the current blood pressure monitoring requirements.

[0003] The blood pressure monitoring method based on photoplethysmogram (PPG) has the advantages of non-invasiveness, simplicity and comfort. Wearable blood pressure monitors developed based on this method are increasingly widely used in the medical field. However, there is currently a lack of PPG blood pressure monitoring devices integrated into cardiopulmonary exercise testing.

[0004] Traditional PPG monitoring methods often require the preparation of separate acquisition devices. Patients place their finger pads on the sensors for signal extraction and analysis. However, for the scenario of monitoring during exercise, patients can only collect signals through the acquisition device by taking their hands off the handlebars of the ergometer, which brings inconvenience in measurement, may cause patients to lose balance during exercise, and increases potential exercise risks. Therefore, the development of safe, convenient PPG monitoring devices suitable for exercise scenarios is of great benefit to cardiovascular disease patients. Summary of the Utility Model
