Method and intelligent bed for detecting respiration rates and heart rates without constraints

Abstract

The invention relates to a method and an intelligent bed for detecting respiration rates and heart rates without constraints. The method includes steps of 1), preprocessing heart impact signals; 2), preprocessing respiration signals; 3), analyzing signal cycles, to be more specific, detecting wave peaks of 2n preprocessed pressure signals and preprocessed acceleration signals and carrying out threshold judgment on the preprocessed pressure signals and the preprocessed acceleration signals to obtain respiration and heartbeat cycles of users; 4), computing the heart rates and the respiration rates, to be more specific, dividing the heartbeat cycles obtained at the step 3) by 60 to obtain the heart rates of the users, acquiring 2n respiration cycles by 2n pressure sensors by the aid of the step 3), computing average values of the 2n respiration cycles to obtain average respiration cycles, and dividing the average respiration cycles by 60 to obtain the respiration rates of the users. The method and the intelligent bed have the advantages that vibration acceleration of a bed can change by the aid of heart impact, the heart rates can be extracted by the aid of the change of the vibration acceleration of the bed, the respiration rates can be extracted by the aid of change of pressures which are applied by the thoracic cavities to the bed in respiration movement, and accordingly the heart rates and the respiration rates can be detected without the constraints; the method and the intelligent bed are high in output accuracy and recognition speed and good in real-time performance.

Description

technical field [0001] The invention relates to the fields of smart home and medical equipment, in particular to a method for unfettered detection of breathing rate and heart rate and a smart bed. Background technique [0002] With the improvement of living standards, people's demand for monitoring their own health continues to increase. Breathing rate and heart rate are the most basic human physiological activities. Morbid signs of the human body are often reflected in abnormal breathing rate and heartbeat beats, thus realizing The daily monitoring of breathing rate and heart rate is of great significance to health assessment and even disease prevention. Sleep monitoring is one of the most effective methods to obtain physiological parameters. However, polysomnography and electrocardiographs currently used in medical institutions cannot be used for long-term monitoring, let alone meet the needs of daily use due to their strong constraints, complicated operations, and high co...

Problems solved by technology

[0003] There is already a bed with heart rate and respiration detection (Chinese patent application number: 201510632987.3), which uses the photoelectric detection method of infrared beams to detect the real-time heart rate and respiration of patients on the bed. a certain attitude, a certain restraint

There is also a real-time and accurate algorithm and system for measuring heart rate and respiration (Chinese patent application number: 201610711512.8). This system uses a highly sensitive piezoelectric sensor integrated in the mattress to detect respiration and heart rate. The signal source is single, and heartbeat and respiration The signals are coupled together, and false detection and missed detection are prone to occur during the separation process
