In-body fluid volume measurement method and in-body fluid volume measuring instrument based on ion induction principle

Abstract

The invention discloses a determination method of a fluid volume in vivo based on an ion induction principle and a measuring instrument of a fluid volume in vivo. The determination method consists of a charged ion partition arrangement analysis model and a multi-frequency fitting separation model, the matched measuring instrument consists of an acquisition sensor, a communication circuit, a processing core MCU (Micro Controller Unit) and a battery for power supply. The determination method and the measuring instrument disclosed by the invention can quickly analyze the fluid volume in vivo of an organism in real time, the ion induction charge which is obviously related to the total amount of the fluid volume in vivo can be measured through a non-contacting and purely physical mode so as to conclude the liquid volume in vivo. Through the measuring instrument, the collaborative analysis can be performed on the obtained inductive charge value and the frequency rate of the rise of temperature and humidity, the breathability, water absorption and the like of a hygroscopic nursing material can be evaluated and the comfortable situation is monitored. In addition, the measuring instrument also comprises a mobile terminal and a remote server software system, the remote control can be performed on the measuring instrument at the mobile terminal after the communication circuit is connected with the measuring instrument, and the uploaded data can be further analyzed, stored, managed and visualized.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to the measurement of the body fluid volume of a human body. Background technique [0002] The body contains a lot of water. These waters and various substances dissolved in the water are collectively called body fluids. Various hormones secreted by many endocrine cells regulate the functions of the body through the circulation of body fluids. [0003] The main function of body fluid regulation is to maintain the homeostasis of the internal environment. The homeostasis of the internal environment is a necessary condition for cells to maintain normal physiological functions and for the body to maintain normal life activities. An imbalance in the homeostasis of the internal environment can lead to diseases. Quantitative measurement is important. [0004] Nowadays, there are many solutions for measuring the volume of biological fluids in the body, but most of them use surgical m...

AI Technical Summary

Problems solved by technology

Among them, the method of body fluid outflow is the most primitive, but it is very traumatic to the user, and the measurement results are often easily affected by various problems such as pipeline blockage and interstitial fluid deposition; the puncture instrument for tissue is simple, but it can only target epithelial tissue, and it is relatively difficult for the body. It is impossible or difficult to measure the amount of body fluid in deep muscle tissue and connective tissue, and the implementation of puncture requires high accuracy and skill of medical personnel, and there are many complications after surgery; sensor implantation is a A solution that achieves real-time measurement as in the present invention requires placing the sensor in the skin of the subject to communicate with the body fluid of the subject. Electrical devices and their cables or radio waves have a greater impact on the health of users

In summary, these invasive detection methods are widely used at present, but these methods inevitably bring more physical pain and inconvenience to users

[0005] It can be seen that in recent years, there have been many researches on the detection methods of biological fluids in the body at home and abroad, but these are only for invasive detection solutions, which can be efficiently and accurately applied to non-invasive instruments for measuring the volume of biological fluids in clinical practice. rare
