Crib mattress with heart rate and breath detection function and control method of crib mattress

Abstract

The invention discloses a crib mattress with a heart rate and breath detection function. A mattress body is provided with a vacuum layer and a U-shaped air groove which are of an integrated structureand are formed in a communicating mode; a surface acoustic wave sensor conducts signal transmission together with a reader through a signal transmission antenna module; a piezoelectric substrate is arranged on the lower side of the U-shaped air groove, and the top face of the piezoelectric substrate touches the bottom of the U-shaped air groove; and an input interdigital transducer and an output interdigital transducer are symmetrically distributed at the two ends of the piezoelectric substrate correspondingly and arranged on the left side and the right side of the U-shaped air groove correspondingly. Passive wireless real-time detection can be achieved, non-touching measurement is adopted in the detection process, collected data are subjected to signal processing, then heart rate and breath condition data of an infant can be quickly and accurately detected in real time, and harm caused by uncertain factors such as electromagnetic wave high-intensity detection and electric leakage to the infant is avoided.

Description

technical field [0001] The invention relates to the field of health state data acquisition devices, in particular to a baby mattress with heart rate and breathing detection and a control method thereof. Background technique [0002] With the development of science and technology, modern technology is gradually integrated into people's daily life. It is very important to use some simple and convenient scientific devices to monitor the heart rate and breathing conditions of the human body in real time, especially when the organs of infants and young children are in the stage of rapid development. Heart rate and respiration play a vital role in the health of infants. At the same time, heart rate and respiration are also the most important physiological parameters for the physical development of infants and young children. The current detection methods for heart rate and respiration are as follows. 1. Many wearable electronic products currently on the market are used to detect h...

Although this method is much lighter and more flexible, the fixed belt has a strong sense of restraint, and the transmission line will also affect the activities of the measured object; and it needs power supply, which is easy to introduce high voltage danger

[0004] Chinese patent CN106175695A discloses a detection system for sleep apnea syndrome. The detection system uses a fingertip signal acquisition device to collect photoelectric signals representing blood volume changes in fingertip blood vessels, and converts the above photoelectric signals into photoelectric volumes. Pulse wave data, and wirelessly transmit the photoplethysmography data to the signal conversion module in real time; the signal conversion module receives the photoplethysmography data output by the fingertip signal acquisition device, and obtains blood oxygen saturation through filtering and calculation Degree data, heart rate variability data and pulse rate data, and transmit the data to the data processing module; the data processing module outputs sleep state data and respiratory event data based on photoplethysmography data, etc. However, this measurement method also requires power supply, During the acquisition process, the acquisition device needs to be in direct contact with the human body, which will also have some impact on the health of the baby, and the entire measurement process is relatively cumbersome, and certain errors will be generated in the measurement results during the complex information conversion process
