Wrist accessory-free blood oxygen measurement equipment and manufacturing method thereof

Abstract

The invention discloses a wrist-type blood oxygen measuring device without accessories and a manufacturing method thereof. The device comprises a PCBA circuit main board and an FPC flexible circuit board arranged on the PCBA circuit main board. The left and right sides of the FPC flexible circuit board are respectively A photosensitive sensor and a red / infrared dual light source light-emitting diode are fixed, an FPC bearing part is arranged on the FPC flexible circuit board, a housing measurement contact part is fixed on the FPC bearing part, and a spacer is integrally formed on the housing measurement contact part. Light wall and light-blocking wall; add a light-blocking wall between the photosensitive sensor and the red / infrared dual light source light-emitting diode, which can better block the light emitted by the light-emitting diode from being directly reflected by the surface of the skin under test to the photosensitive sensor that receives the signal; A light-blocking wall is added around the soft rubber to better isolate the signal interference of ambient light on the signal receiver, thus significantly improving the measurement accuracy.

Description

technical field [0001] The invention relates to a vital sign monitoring wristband capable of measuring human health parameters, in particular to a wrist-type wristband device for measuring human blood oxygen saturation parameters without accessories and a manufacturing method thereof, belonging to the technical field of wearable medical devices. Background technique [0002] With the accelerated pace of life and work, the increased pressure of competition, the expansion of social experience and the change of way of thinking, it has brought some potential impacts on people's health, and has also caused more and more people to be in a sub-healthy state. Therefore, the importance of physical examination becomes more and more important. Nowadays, people are paying more and more attention to the health of themselves and their families. They will conduct routine physical examinations every year. Most of the physical examinations are done in hospitals or medical institutions throug...

Problems solved by technology

However, there will be insufficient light blocking between the light-emitting diode and the photosensitive sensor during use, so that a part of the emitted light emitted by the inventive diode is directly reflected to the receiving end of the photosensitive sensor, resulting in an error in the collection signal and measurement error; contact with the skin The outer shell is hard shell, and the friction between it and the skin is small, which can easily cause the signal acquisition part to slide relative to the skin, resulting in unstable acquisition signals and resulting measurement errors; ambient light affects the collection of acquisition signals, and there will also be Measurement error

[0004] At the same time, because the blood vessels at the fingertips of the human body are the most abundant, the existing blood oxygen measuring devices almost all collect the blood oxygen saturation sample parameters at the fingertips of the human body. Although the collection results can reach a relatively accurate degree, the collection The equipment must be attached with the attached fingertip holding device accessories to collect the blood oxygen saturation parameters of the human body, that is, the blood oxygen measuring devices in the prior art are all collection equipment with accessories, which are cumbersome to operate, inconvenient to use, and easy to use. produce measurement error
