System for detecting physical signs of human body

Abstract

The invention relates to a system for detecting physical signs of human body. The system comprises a power module, a storage module, a pressure switch module, a pressure shaking conversion module, a gravitational acceleration detection module, an optical fiber sensing pad, an optical transceiver module, a photoelectric transducer, an electro-optic transducer, a filter, a signal amplifier and a central controller. The central controller is used for controlling the optical fiber sensing pad to collect pressure data, controlling the pressure shaking conversion module and the gravitational acceleration detection module to collect vibration data, and analyzing and treating the pressure data and the vibration data, so as to acquire the physical signs of human body, including heartbeat frequencydata and respiratory rate data. The system provided by the invention is capable of calculating accurate parameters of physical signs of human body even under the condition of weak pressure signal, andthe whole monitoring system has the advantages of high applicability to more people, wider weight range, higher gesture adaptability, and the like.

Description

technical field [0001] The invention relates to the technical field of data monitoring, in particular to a human body sign detection system. Background technique [0002] Health and wellness monitoring has become an area of ​​increasing concern with the advent of internet-connected devices and the digital healthcare industry. Monitoring of human vital signs such as heart rate, cardiac shock signals, and respiration rate is required both in and outside of healthcare settings. In healthcare settings, vital sign tracking can be essential for ensuring patient safety, diagnosing disease, monitoring patient progress, and planning patient care when healthcare providers are not at the bedside. Outside of the healthcare setting, tracking vital signs enables individuals to quantify and conceptualize their health status, thereby helping individuals stay focused on their health and wellness needs, gain clarity on progress, and maintain the motivation needed to achieve health and fitnes...

Problems solved by technology

[0003] At present, there are also products on the market that detect human body signs through optical fiber pressure sensors, but the optical fiber pressure sensors of this product can only monitor the signal generated by the pressure in the vertical direction, but cannot detect the signal fluctuation in the horizontal direction. When the pressure is light The signal detected by a simple optical fiber pressure sensor will be relatively weak, such as when the body weight is light, or the lying part is just in the physiological arched part, or when the shakeable nursing bed is shaken to a certain angle and the pressure is weak

In the case of weak pressure, it is impossible to accurately calculate and measure, so that it is difficult to accurately detect the information of human body signs, and it also makes the applicability of the entire human body sign detection system poor.

In addition, it is difficult to achieve a large size of the optical fiber pressure sensor in terms of manufacturing cost and process, especially when the width of the bed exceeds 90cm, the original optical fiber pressure sensor needs to be more than 90cm wide and still get good monitoring results. It takes a lot of money. high cost
