Intelligent wireless body temperature and excretion event detecting sensor

Abstract

The invention discloses an intelligent wireless body temperature and excretion event detection sensor, which belongs to the field of medical and household use. The smart sensor has the functions of body temperature measurement, excretion event detection, body temperature monitoring, and body temperature recording; it consists of three parts: a detachable sensor cable, a body temperature and excrement impedance measurement main module, and related APP applications. The main module uses high-precision and low-power devices such as voltage references and instrument amplifiers to realize signal processing of temperature and impedance, and uses a mixed-function single-chip microcomputer to complete digitization, signal processing algorithms and wireless signal transmission; Delivered directly; rechargeable battery charges with phone USB cable. The separate sensor cable probe can be used to measure body temperature, and can also be placed in a diaper to detect the number and time of urination and defecation by detecting excrement temperature and impedance changes. APP application and sensor communication protocol support multiple ways to display and manage information of single or multiple sensors.

Description

technical field [0001] This patent relates to an intelligent wireless body temperature and excretion event detection sensor, which belongs to the medical and household fields. Background technique [0002] After the emergence of low-power Bluetooth and WIFI technologies, various wearable technologies and products for sports, health care, and health preservation have emerged. At present, various wireless smart electronic thermometer products designed using low-power bluetooth technology, as well as various patents applied for, most of them belong to the household field. Typical examples are the use model patent with application number 201520527658.8, the invention patent with application number 201410300436.2, the use model patent with 201520155471. The form of integration of thermistor sensor element and Bluetooth module is adopted. This method only considers the use of a dedicated home user. The entire wireless smart sensor can be attached to the armpit or tied to the arm...

AI Technical Summary

Problems solved by technology

This method only considers the use of a dedicated home user. The entire wireless smart sensor can be attached to the armpit or tied to the arm of the infant, which is easy to carry or wear, so it is very suitable for home use; but in the hospital environment, due to a The sensor needs to be used by many people, so cleaning and avoiding cross-contamination need to be well considered

In addition, most parents who use wireless smart body temperature sensors / thermometers still have concerns about the radiation of wireless products, worrying that wearing / attaching Bluetooth products with long-term electromagnetic radiation to their children will affect their growth and development

Although the electromagnetic radiation of these products is at the safe dose required by the regulations, for newborns, these regulations are safe for adults, and there is no conclusive evidence and conclusions on the impact on infants and young children, so this drawback also affects use of these products

[0003] In addition, these household smart thermometers do not need to be used every day of the year because family members do not have many fevers. Therefore, most of the products use disposable button batteries, which can be used continuously for several weeks to a year; Environment, it is a waste to change the battery due to such frequent use, which also causes inconvenience and increases the cost of use
