Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a cardiopulmonary exercise test mask fixing device. Background Art

[0002] As an objective, quantitative, and non-invasive examination method, cardiopulmonary exercise testing is widely used in clinical practice. It can not only clarify the pathophysiological mechanism of exercise intolerance and exercise-related symptoms, but also has important clinical value in differential diagnosis of diseases, prognosis evaluation, evaluation of medical intervention effects, exercise prescription formulation, and preoperative evaluation of surgical operations.

[0003] The specific operation method of the cardiopulmonary exercise test is to use gas analysis technology to calculate parameters such as oxygen uptake and carbon dioxide emissions by measuring the process of the human body from a resting state to a maximum exertion state and then returning to a resting state under a gradually increasing exercise load. At the same time, a series of changes in indicators such as heart rate, blood pressure, blood oxygen saturation and electrocardiogram changes are obtained, and the corresponding symptoms that occur in the subjects during the test are recorded to objectively reflect the pathophysiological changes and the degree of functional impairment that occur under different load levels, thereby comprehensively evaluating the overall function and reserve capacity of organ systems such as the heart and lungs.

[0004] The gas collection and analysis part during the cardiopulmonary exercise test is completed through professionally designed masks, respiratory management and gas analyzers. The mask usually needs to be fixed to the subject's head with a professional headband. The headbands commonly used in clinical practice are mostly made of elastic nylon material. The headband has buckles that can be connected to the mask. The position of the buckle on the headband can be adjusted by Velcro fixed on the headband. However, the existing headbands on the market are inconvenient to clean and disinfect, the headbands are severely worn after multiple cleanings and disinfections, and the reuse rate is low. In addition, the existing headbands also have the disadvantages of limited adjustable range and the need to replace different models of headbands when used by adults and children.
