Medical wristband with self-compensation function and self-compensation method

Abstract

The invention relates to the technical field of medical electronics and in particular relates to a medical wristband with a self-compensation function and capable of offsetting blood oxygen measurement interference due to movements of a user when the user wears the wristband. Movement compensation is realized via gravitational acceleration, and interference factors produced during the daily use ofthe wristband can be eliminated; accurate and reliable blood oxygen saturation measurement can be achieved; a boss, mounted on the bottom of a wristband body, is keen to skin, so a temperature sensor, a photosensitive sensor and a light source projection window can be well applied to the wrist skin, and position of the wristband during the movement of the user can be positioned; and relative displacement between the temperature sensor and the photosensitive sensor and the wrist skin can be prevented, so measurement error during the movement can be reduced or eliminated.

Problems solved by technology

[0002] With the advancement of science and technology and the improvement of human living standards, people have paid more and more attention to health. Routine physical examination and preventive treatment have been widely recognized by people. However, due to the accelerated pace of work and life in modern society , People are busy with work and other affairs, coupled with the shortage of medical resources in hospitals today, it is difficult for people to go to the hospital for regular health testing, and the medical testing equipment in hospitals is usually bulky, expensive, cumbersome and difficult to carry It is not suitable for family and personal purchase. In an environment that lacks normalized and fast health testing methods, it is not convenient for people to discover early changes in physical health indicators in time, and it is not conducive to early implementation of corrective and preventive plans, which will cause serious diseases in the future. Hidden danger

How to conveniently and quickly normalize the detection of personal physiological health indicators has become an urgent need for people today. For this reason, wearable multi-parameter health index collection medical devices have emerged. For example, Chinese patent document CN202600374U discloses a pulse measuring type However, it has a single function and can only measure the pulse of the human body; Chinese patent document CN102866619A discloses a multifunctional watch that can detect the wearer's blood pressure and heart condition in real time. When the wearer's blood pressure increases or tachycardia, The buzzer sounds different music to remind the wearer not to get emotional and pay attention to physical health, but it lacks the detection of important health indicators such as blood oxygen and body temperature

Chinese patent document CN201519143U discloses a method and structure of a portable integrated multi-parameter physiological detector, in which multiple detection components are arranged in a detection box, which has poor contact and matching with different human bodies

Chinese patent document CN103720461A discloses a wearable multi-parameter physiological index collector. All the measuring components are arranged in the shell, which can collect human pulse, blood oxygen saturation, body temperature and electrocardiogram. The technology and The structure is only suitable for measurement near the Waiguan point on the wrist on the back of the hand, and the blood vessels on the wrist are not rich, and the pulse is also very weak, resulting in large errors in the measured data, which is very inaccurate and cannot satisfy people's health concerns. Accuracy requirements for indicator collection and display

[0003] More importantly, in the above-mentioned several patent documents, the method of static measurement is used to measure one or more health indicators. As a wearable detection device, especially a wristband with detection function worn on the wrist, sports Various disturbances in the process will cause great interference to the measurement data, and the measurement data obtained by the static measurement method obviously lack authenticity and accuracy
