Human body excretion detecting and monitoring method and system

Abstract

The invention belongs to the field of medical monitoring equipment, and relates to a human body excretion detecting and monitoring method and system.Excrement contains water with weak conductivity, and the temperature of the excrement is the temperature in the body.The temperature and impedance of the excrement are indirectly measured, the change rule of the temperature and impedance of the excrement is analyzed, and thus the aim of detection is achieved.The monitoring system described in the invention is composed of an excretion detecting device and a monitoring terminal.The detecting device collects excrement impedance signals through a thermal-sensitive / humidity-sensitive resistor, the excrement impedance signals are digitized by a single-chip microcomputer after being amplified, whether excretion occurs or not is detected through a matching algorithm, and finally excretion information is broadcast through a wireless communication module.When the wireless monitoring terminal is within the irradiation range of broadcast signals, the content of the information can be received and displayed on the terminal, and nursing personnel are reminded of treatment in time.The excretion information is further uploaded to a remote health cloud server through the wireless terminal, and the server can push the information to other remote terminals for historical information remote inquiry and monitoring.The Bluetooth or WIFI or other technologies are adopted in wireless transmission.

Description

technical field [0001] This patent belongs to the technical field of household and medical medical monitoring equipment, and particularly relates to a method and device for detecting excretion of adults and infants who cannot sense excretion and cannot take care of themselves. Background technique [0002] Urinary incontinence, hemiplegia, dementia-type adults, infants, newborns, etc. all have situations that require nursing care from others. [0003] Although it is not a big problem if the urination and defecation tests of infants and paralyzed patients are not timely; but if the long-term care is not good, it will lead to skin ulcers and allergies on the lower body. Conveniently and quickly detect the urination and defecation time of infants and paraplegic patients, and remind nursing staff to change diapers in time can improve the comfort of infants and the nursing quality of nursing staff. [0004] The current high-end diapers use the urine display function to solve thi...

AI Technical Summary

Problems solved by technology

[0012] (2) The manufacturing cost is high; the use cost is high; it is not environmentally friendly;

[0013] (3) There are unsafe features: the electrolyte is used to generate electricity to drive the electronic part; there is a risk of leakage, especially for newborns and infants, which may cause skin damage;

[0014] (4) The wireless transmitting part is in the diaper, and the transmitting part is very close to the reproductive organs. The energy of electromagnetic radiation is inversely proportional to the square of the distance from the transmitting source; although the transmitting energy is within the safe range, it is not ruled out if it is too close to the radiation source and used for a long time. There are certain unsafe factors, especially Chinese mothers are very concerned about radiation issues;

[0015] (5) In hospitals / neonatal wards that require cluster monitoring, when multiple diapers are used at the same time, the numbering and identification are inconvenient to use; they need to be re-paired with the wearer after each replacement; it does not conform to the normal use method; a new one is added workload;

[0016] (6) Discarded used diapers also have the problem of continuing to transmit wireless signals; this may increase identification interference;

[0017] (7) Due to the characteristics of one-time use, the self-contained electric energy cannot be very abundant, and there is a problem that excretion occurs after the battery power is exhausted, resulting in undetectable problems;

This kind of bluetooth thermometer is integrated with sensor, signal processing and wireless transmission module. It is too close to the genitals for urine testing, and there are hidden dangers of radiation; and there are also big cleaning problems, which are not easy to use.

[0020] At present, there is still a method of using a humidity sensor to be attached to the outside of the diaper for detection; however, due to the humidity sensor used, the humidity change can only be measured in a ventilated environment, and the ventilation outside the diaper generally does not necessarily meet the requirements, and the diaper When the humidity outside changes greatly, the humidity inside is generally very high, and the excretion event has been passed for a long time, so it cannot play a good role in urine detection
