Wrist accessory-free blood oxygen measurement equipment capable of being attached to skin automatically and manufacturing method of wrist accessory-free blood oxygen measurement equipment

Abstract

The invention discloses wrist accessory-free blood oxygen measurement equipment capable of being attached to skin automatically. The wrist accessory-free blood oxygen measurement equipment comprises a casing (01), a PCBA (printed circuit board assembly) circuit mainboard (05) and an FPC (flexible printed circuit) (04) arranged on the PCBA circuit mainboard (05), wherein a photosensitive sensor (10) and a red / infrared dual-light-source light emitting diode (11) are arranged on the FPC (04); an FPC bearing part (02) is further arranged on the FPC (04); the casing (01) and the FPC bearing part (02) are connected into a whole through an elastic arm (03); the elastic arm (03) adopts a hollow ring ladder shape and is big-end-down. The contact force of a signal collecting part and the skin can be automatically regulated by the elastic arm (03) and can automatically adapt to the wrist diameter, and the attachment degree of signal collection is guaranteed, so that the comfort level of wearing and the accuracy of blood oxygen measurement are remarkably improved.

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 blood oxygen saturation parameters of a human body without accessories, and belongs 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 through physical examination ...

AI Technical Summary

Problems solved by technology

In the prior art wrist-type blood oxygen saturation measuring bracelet, the printed boards welded with light-emitting diodes LED and photoelectric sensor PD are all connected to the plastic watch case, and the whole is made of rigid material, and the friction between it and the skin is not strong. Large, and because of the large volume of the rigid part, it is easy to cause strong relative sliding between the signal collection part and the collected skin. During the signal collection process, when the user turns over or turns the wrist, etc. Due to the limitation of the physiological structure on the back of the wrist, it is easy for the light-emitting diode LED or the photoelectric sensor PD to detach from the skin, resulting in a serious decrease in the quality of signal acquisition, causing difficulties or distortions in signal acquisition, resulting in large measurement errors
