耳戴式体征监测系统Ear-worn sign monitoring system

技术领域technical field

背景技术Background technique

医疗设备的便携化、小型化已成为该领域的发展趋势。脉搏血氧仪就是在这种趋势下出现的,它提供了以无创方式测量血氧饱和度或动脉血红蛋白饱和度的方法,并且可以检测动脉脉动,因此也可以计算并告知病人的心率,具有体积小、便于携带的优点,适合家用。The portability and miniaturization of medical equipment has become the development trend in this field. Pulse oximeters emerged from this trend, providing a non-invasive way to measure blood oxygen saturation or arterial hemoglobin saturation, and can detect arterial pulsation, so can also calculate and inform the patient's heart rate, with volumetric The advantage of being small and easy to carry is suitable for home use.

目前,比较普遍的脉搏血氧仪为指夹式,它利用在脉动期间所吸收的光量与血液中的氧含量有关这一原理,分别驱动红光(660纳米)和红外光(940纳米)交替照射指尖,通过计算二者通过身体后的强度比值得到血氧含量。但实际上,这种血氧仪虽然能实现血氧、心率的实时检测,但使用时佩戴在手腕上,探头夹在手指上,非常不方便,特别是在运动的时候,而且功能单一,没有考虑到用户的各种需求,不能很好的丰富用户的体验,适用范围较窄。At present, the more common pulse oximeter is a finger clip type, which uses the principle that the amount of light absorbed during the pulsation is related to the oxygen content in the blood, and drives red light (660 nanometers) and infrared light (940 nanometers) alternately. The fingertips are irradiated, and the blood oxygen content is obtained by calculating the intensity ratio of the two after passing through the body. But in fact, although this kind of oximeter can realize real-time detection of blood oxygen and heart rate, it is very inconvenient to wear it on the wrist and clamp the probe on the finger when using it, especially when exercising, and it has a single function and no Considering the various needs of users, it cannot enrich the user experience very well, and the scope of application is narrow.

经过对现有技术的检索发现,中国专利文献号CN102068261A,公开(公告)日2011.05.25,公开了一种安全监护仪,尤指一种集成多功能可对佩戴者进行实时监护的安全监护仪。包括中央处理模块、报警模块和检测传感模块,所述报警模块和检测传感模块分别连接于所述中央处理模块,所述检测传感模块包括速度传感器,所述速度传感器设置为将异常运动体征反馈至所述中央处理模块,所述中央处理模块设置为处理所述异常运动体征,并指令报警模块予以报警。采用该技术安全监护仪,当佩戴者发生意外能够自动发出警报,提醒医护人员或者佩戴者周围的人员及时施救。但该技术使用的传感器模块较多,结合中央处理器模块难以实现小型化和便携性,使得该监护仪的佩戴使用造成难度。After searching the prior art, it is found that the Chinese Patent Document No. CN102068261A, published (announcement) date 2011.05.25, discloses a safety monitor, especially a safety monitor that integrates multiple functions and can monitor the wearer in real time . It includes a central processing module, an alarm module and a detection and sensing module, the alarm module and the detection and sensing module are respectively connected to the central processing module, the detection and sensing module includes a speed sensor, and the speed sensor is set to detect abnormal movement The signs are fed back to the central processing module, and the central processing module is configured to process the abnormal movement signs and instruct the alarm module to give an alarm. Using this technical safety monitor, when the wearer has an accident, it can automatically send out an alarm to remind the medical staff or the people around the wearer to rescue in time. However, there are many sensor modules used in this technology, and it is difficult to realize miniaturization and portability in combination with a central processing unit module, which makes it difficult to wear and use the monitor.

技术效果technical effect

与现有技术相比,本发明仅仅使用了一个耳夹式或者透射式探头,体积非常小,而且结合其他模块(除显示模块)之后可方便地佩戴于耳朵上(佩戴方式如蓝牙耳机),而且显示模块为手机客户端,没有结合在系统上,进一步减小了体积。而且本发明目的在于“运动中方便地检测血氧和心率、计步同时可以进行异常报警和长期监护”,以最简洁的方式实现了全方位的监护,同时易于佩戴,具有良好的便携性。对于目前的光学测量血氧方案,在运动下难以进行准确测量。本发明中,基于运动传感器鉴别使用者运动状态,当使用者处于静止状态时,进行血氧心率的信息采集,这样可能间歇完成对使用者的血氧心率监护,同时保证了测量精度。同时,传感器的减少有助于降低系统的功耗,实现系统的低功耗设计,这对可穿戴设备有着重要意义。Compared with the prior art, the present invention only uses an ear clip-type or transmission-type probe, which is very small in size and can be conveniently worn on the ear (such as a Bluetooth headset) after being combined with other modules (except the display module).

For the current optical blood oxygen measurement scheme, it is difficult to measure accurately under exercise. In the present invention, based on the motion sensor to identify the user's motion state, when the user is in a static state, the blood oxygen and heart rate information is collected, so that the monitoring of the user's blood oxygen heart rate can be completed intermittently, while ensuring the measurement accuracy. At the same time, the reduction of sensors helps to reduce the power consumption of the system and realize the low power consumption design of the system, which is of great significance to wearable devices.

本装置能够实现的技术效果包括:The technical effects that the device can achieve include:

1.使用加速度计与陀螺仪传感器,借助微处理器进行信息的采集与处理,完成对运动状态的测定,同时记录不同运动状态下的运动量。例如,可以记录走路步数,跑步步数或者上楼下楼步数等。1. Using accelerometer and gyroscope sensors, with the help of microprocessors to collect and process information, to complete the determination of the motion state, and record the amount of motion under different motion states at the same time. For example, you can record the number of steps you walk, the number of steps you run, or the number of steps you go up and down stairs.

2.借助加速度计和陀螺仪传感器,可以测定人体运动状态,当人体处于静止状态时,可以启动血氧采集模块,进行高精度的血氧测量。采用光学传感器采集采用血氧信息收到运动干扰很大,难以实现准确测量。利用使用者的静止间隙进行血氧测量可以克服该难点,同时,因为血氧心率不会突变,采用该种方式实现的离散采样同样可以还原使用者佩戴过程中的血氧心率信息。2. With the help of accelerometer and gyroscope sensors, the state of human motion can be measured. When the human body is in a static state, the blood oxygen collection module can be activated to perform high-precision blood oxygen measurement. The use of optical sensors to collect and use blood oxygen information is greatly disturbed by motion, and it is difficult to achieve accurate measurement. Using the user's resting gap to measure blood oxygen can overcome this difficulty. At the same time, because the blood oxygen heart rate will not change suddenly, the discrete sampling achieved in this way can also restore the blood oxygen heart rate information during the wearing process of the user.

3.同时具有数据存储和无线发射功能。数据存储可以将运动信息、心率血样信息进行记录,无线发射模块可以将数据发送到智能终端,如智能手机,平板等。发送信息包括实时信息,或者存储模块存储的历史数据,同时受到智能终端的反馈指令控制。3. At the same time, it has the functions of data storage and wireless transmission. The data storage can record exercise information, heart rate and blood sample information, and the wireless transmission module can send the data to smart terminals, such as smart phones, tablets, etc. The sent information includes real-time information, or historical data stored by the storage module, and is controlled by feedback instructions from the smart terminal.
