The invention provides an undisturbed human-body physiological signal-collection band. The undisturbed human-body physiological signal-collection band comprises a lower piece assembly, an upper pieceassembly and a piezoelectric film, wherein the piezoelectric film is clamped between the lower piece assembly and the upper piece assembly, one end of the lower piece assembly is provided with a signal output base, one end of the piezoelectric film is provided with a signal exporting wire, the signal exporting wire is connected with the signal output base, grooves are formed in the edges of the lower piece assembly, bulges are arranged on the portions, corresponding to the grooves, on the edges of the upper piece assembly, glue is placed in the grooves, the bulges are bonded with the grooves through the glue, and teeth which are distributed in parallel at equal intervals are arranged on the inner surface, in contact with the piezoelectric film, of at least one of the lower piece assembly and the upper piece assembly. According to the undisturbed human-body physiological signal-collection band, the bonded structure is adopted to achieve connection between the structures of the signal collecting band, wearing is not needed to collect human-body physiological signals, and physical sign signals are collected in the mode that the teeth are in contact with the piezoelectric film, so thatthe accuracy of data collection is improved.

Description

Technical field [0001] The invention relates to the technical field of medical devices, and in particular to an undisturbed human physiological signal collection belt. Background technique [0002] The collection of physiological electrical signals is usually used in animal and human experiments in medicine, psychology and other disciplines. It is more commonly used in medical multi-parameter monitoring systems and a large number of diagnosis and treatment equipment (such as heart, EEG, polysomnography, etc.). Physiological electrical signals can reflect various physiological and neural activities of animals and humans. Therefore, the collection of physiological electrical signals is an essential part of the above-mentioned device. [0003] At present, real-time monitoring of vital signs signals of various groups of people in daily life scenarios requires the use of wearable devices (such as electronic bracelets, collars, vests, etc.). However, the current use of wearable devices ...

Problems solved by technology

However, the current use of wearable devices to collect vital signs signals mainly has the following defects: 1) It is necessary to closely contact the signal electrodes with the human skin to collect the pressure signals generated by the muscles and convert them into electrical signals for processing to obtain important physiological signals of the human body , such as heartbeat, breathing and convulsions and other physiological signals, in the process of collecting physiological signals, they need to be in close contact with human skin, which will bring a lot of inconvenience to users during use; 2) signal electrodes need to be pasted when collecting On the surface of the human skin, different impedances may be formed due to different positions of the human skin each time, resulting in unstable strength (amplitude) of the collected signal, making it impossible to accurately collect the required physiological signal

However, in this patent application, the surface of the flexible pad is rough, but the contact surface between the flexible pad and the piezoelectric film sensor is smooth, and its working principle is still to collect the tension of the stress point of the flexible pad through the piezoelectric film sensor. There is still the problem that the device cannot accurately collect the above-mentioned sign signals if the small pressure fluctuations caused by changes in breathing, pulse or heartbeat are not enough to cause stretching and deformation at the stress point

[0006] In addition, the human physiological signal acquisition devices currently on the market generally use screws to fasten and connect the devices. It is to convert the pressure signal into a micro-electrical signal. The existence of metal will have a certain impact on the collection and transformation of the micro-electrical signal, especially in a precision device such as physiological signal collection, which will have a greater impact on the accuracy of signal collection. adverse effects of
