AI Technical Summary

Technical Problem

Existing blood oxygen monitoring devices suffer from problems such as unstable wear, significant signal interference, and inaccurate readings in children, especially infants. They are particularly difficult to monitor continuously under conditions of low perfusion or activity. Furthermore, traditional devices are not suitable for children, which affects the stability and reliability of monitoring.

Method used

A children's wristband-style wearable blood oxygen monitor was designed. It uses a skin-friendly silicone material and a flexible, bendable material to make a fixing strap and a fingertip monitoring component. Combined with a display module, it forms a stable wristband structure. It has a built-in blood oxygen sensor component and supports switching between multiple working modes, including blood oxygen monitoring and a fun audio-visual mode.

Benefits of technology

It improves the stability and reliability of blood oxygen monitoring for children, is suitable for long-term wear, reduces data fluctuations caused by activity or crying, enhances the stability and comfort of signal acquisition, and is suitable for blood oxygen monitoring of children of different ages.

Abstract

The invention relates to the technical field of medical monitoring, and discloses a child bracelet type wearable blood oxygen monitor which comprises a display module and a fixing band, the fixing band and the display module are connected to form a bracelet structure, a fingertip monitoring assembly arranged on a fingertip in a sleeving mode is arranged on one side of the display module, a blood oxygen sensing assembly is arranged on the fingertip monitoring assembly, and the display module is connected with the display module. The display module comprises a shell and a display screen, and the shell, the fixing band, the connecting band and the fingertip monitoring assembly are all made of a skin-friendly silica gel material. The fixing band and the display module form a bracelet structure, and the fingertip monitoring assembly is connected with the display module, so that the device can be stably fixed on the wrist and fingertip parts of a child at the same time. Compared with a traditional single finger clamping type blood oxygen monitoring device, under the condition that children cry and scream, move or are low in matching degree, relative stability of monitored parts can still be kept, and therefore data fluctuation caused by displacement in the monitoring process is reduced.
