A Smartphone-Based Multifunctional Physiological Signal Generator

Abstract

The invention provides a multifunctional physiological signal generator based on a smart phone, which relates to the technical fields of biomedicine and electronic products. The physiological signal generator includes a smart phone, a voltage regulating device and a medical oscilloscope connected in sequence. The smart phone includes a data storage module, a data reading module and a user interaction module. The data storage module is used to store the initial signal data of the signal generator; the data reading module is used to read the initial signal data in the data storage module, and input it to the user interaction module after conversion; the user interaction module is used to receive the user's Select instructions and related operation instructions. The smart phone-based multifunctional physiological signal generator provided by the present invention can update the latest disease or typical physiological signal waveform in real time to ensure real-time generation of physiological signals. At the same time, the cost of the physiological signal generator is low, so that the device can be used as a tool for teachers' teaching and laboratory testing.

Description

technical field [0001] The invention relates to the technical fields of biomedicine and electronic products, in particular to a smart phone-based multifunctional physiological signal generator. Background technique [0002] The multifunctional physiological signal generator is a signal source that can generate physiological signal waveforms such as ECG and EEG. With the development of biomedical engineering and medical equipment in recent years, more and more monitoring equipment and research equipment Fast and convenient test and inspection equipment is required. At present, manufacturers such as ECG monitors mostly use vital sign simulators for quality testing, and the monitoring equipment has disadvantages such as large size and easy to be affected by environmental factors. However, compared with the real physiological signal, the output signal of the traditional physiological signal generator has a waveform that is too neat and repetitive, and cannot represent the real ...

Problems solved by technology

At present, manufacturers such as ECG monitors mostly use vital sign simulators for quality inspection, and the monitoring equipment has disadvantages such as large size and easy to be affected by environmental factors.

However, compared with the real physiological signal, the output signal of the traditional physiological signal generator has a waveform that is too neat and repetitive, and cannot represent the real clinical situation. Respiration and blood pressure signals), and limited by the storage capacity, only a few segments of signals of limited length are stored, so the signals are only played repeatedly, which cannot well reflect the real long-term human physiological signals, and are expensive; in recent years, research has been based on Signal generators for virtual instruments or SOPC, but these generators have problems such as internal physiological signal data cannot be updated in real time, artificially added noise cannot be performed, low portability, poor popularity, etc.
