Vital-sign sensor based on PVDF and remote network sign system

Abstract

The invention relates to a vital-sign sensor based on PVDF and a remote network sign system. The vital-sign sensor comprises an information box, a PVDF piezoelectric film belt and a shell for sealing the PVDF piezoelectric film belt. The information box comprises a filter shaping module, a computing control unit and a communication module, wherein the filter shaping module, the computing control unit and the communication module are sequentially connected; the computing control unit comprises a signal processing module, an expansion interface and an output interface, wherein both the expansion interface and the output interface are connected with the signal processing module. The vital-sign sensor is free of assistance of nurses, free of constraint and suitable for long-term measurement, any one PVDF piezoelectric film in the sensor is only in contact with the body of a user or is in indirect contact with the body of a user, the user transfers body vibration pressure changes of the body to the sensor relying on the dead load of the body or the pressure of limbs, and vital-sign data information of the user can be monitored in real time; the normal work and rest rule of the user is not influenced, the vital-sign sensor is suitable for measuring the vital-sign data information of the user for a long time, the rule and the tendency of the vital-sign data information of the user are summarized accordingly, and the healthy warning and preventing effects are achieved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a PVDF-based vital sign sensor and a remote network sign system. Background technique [0002] In recent years, with the development of science and technology, various portable and wearable smart devices have entered people's field of vision one after another. Coupled with the rapid development of big data and artificial intelligence, people have more confidence in a more comfortable, free and predictable future. for desperate hope. In such a demanding environment, we found that the traditional method of measuring vital signs (mainly referring to breathing and heart rate) has the following three shortcomings: [0003] 1. The measurement process is cumbersome and complicated, requiring the assistance of nursing staff to complete, consuming a lot of nursing resources; [0004] 2. The measurement needs to restrain the user, and the user experience is poor; [0005] 3. The measur...

AI Technical Summary

Problems solved by technology

[0003] 1. The measurement process is cumbersome and complicated, requiring the assistance of nursing staff to complete, consuming a lot of nursing resources;

[0004] 2. The measurement needs to restrain the user, and the user experience is poor;

[0005] 3. The measurement needs to bind the user and the measurement process is cumbersome, which leads to the inability to act on the user's real-time monitoring sign data information for a long time. The amount of data is small and cannot form big data to analyze and predict the health status

[0006] It can be seen that the traditional vital sign measurement method can no longer meet the needs of nursing staff and users, and does not meet the development requirements of science and technology such as big data and cloud intelligence. Therefore, a novel vital sign detection method needs to be realized urgently
