Description
Translated fromChinese技术领域technical field
本实用新型涉及生理参数测量仪器，尤其涉及的是，一种运动和生理信息检测设备。The utility model relates to a physiological parameter measuring instrument, in particular to a motion and physiological information detection device.
背景技术Background technique
生命在于运动。然而，近几十年来，安逸、方便、快捷的生活方式致使运动不足性疾病迅速增多。运动不足可造成学生在生长发育阶段的发育不良，身高和体重达不到平均水平。在中国，与运动不足相关疾病的发病率呈现逐年增高的趋势。国家体改委的一个专项调查发现，中国知识分子的平均寿命与全国平均寿命相比要低10岁左右，有人认为这些与高校中年教师运动不足有关。此外，不少人在运动锻炼过程中，不按照自然规律，不根据自身状况来运动，导致运动过量。运动过量可以导致维生素B12缺乏症，可引起月经异常或血尿，青少年运动过量可能导致贫血。更为严重的是，不少人因运动过量而导致死亡。实践证实，适量的体育运动是保持人体机能、体能处于最佳状态的有效手段。Life is movement. However, in recent decades, the comfortable, convenient, and fast lifestyle has led to a rapid increase in sports insufficiency diseases. Insufficient exercise can cause students to be stunted in their growth and development stages, and their height and weight cannot reach the average level. In China, the incidence of diseases related to lack of exercise is increasing year by year. A special survey conducted by the State Economic Reform Commission found that the average life expectancy of Chinese intellectuals is about 10 years lower than the national average. Some people think that this is related to the lack of exercise among middle-aged teachers in colleges and universities. In addition, many people do not follow the natural laws and do not exercise according to their own conditions during exercise, resulting in excessive exercise. Excessive exercise can lead to vitamin B12 deficiency, which can cause menstrual abnormalities or hematuria, and excessive exercise in adolescents may lead to anemia. What's more serious is that many people die due to excessive exercise. Practice has proved that appropriate amount of physical exercise is an effective means to keep human body function and physical fitness in the best state.
那么如何保证自己所进行的体育运动是适量的，这就需要借助一定的仪器对自身的运动信息和生理信息进行联合检测，得到动态的生理反馈信息，如卡路里消耗量及体温随运动的变化等，从而更合理地安排运动强度和训练方式。而这样的检测仪器市场上已有很多的样式，但是它们都不很理想，都存在以下一种或几种缺陷，比如，有些通过绑在手臂上的PPG技术传感器，获取人体的体温、热通量、加速度信息和皮肤电阻信息，这些产品的信号采取部位均处于运动幅度较大区域，对使用PPG技术提取心率和血氧饱和度而言，由于运动伪迹使有效信号的拾取非常不稳定，不能提取一些对运动干扰相对敏感的生理信号比如，还有些通过贴近于佩戴者耳廓或外耳道的传感器，获取生理信号，这种方式虽然在一定程度上解决了运动干扰对生理信号提取的问题，但该仪器使用的加速度传感器仅用于运动伪差消除，未用于提供用户的运动状态信息。So how to ensure that the amount of physical exercise you do is appropriate, which requires the use of certain instruments to jointly detect your own exercise information and physiological information to obtain dynamic physiological feedback information, such as calorie consumption and changes in body temperature with exercise, etc. , so as to arrange exercise intensity and training methods more reasonably. And there are many styles of such testing instruments on the market, but they are not very ideal, and all have one or more of the following defects. The signal acquisition parts of these products are all in the area of large motion range. For the extraction of heart rate and blood oxygen saturation using PPG technology, the effective signal pickup is very unstable due to motion artifacts. Some physiological signals that are relatively sensitive to motion interference cannot be extracted. For example, some physiological signals are obtained through sensors close to the wearer's auricle or external auditory canal. Although this method solves the problem of motion interference on physiological signal extraction to a certain extent, However, the acceleration sensor used in this instrument is only used for motion artifact elimination, and is not used to provide the user's motion status information.
可见，现有技术存在一定的缺陷，需要进一步地改进。It can be seen that there are certain defects in the prior art, and further improvements are needed.
