Problems solved by technology

Both of the above two methods can play a protective role, but in the first method, when measuring a patient with high blood pressure, if the pressure temporarily exceeds the pressure protection point due to the patient's movement or other interference, the non-invasive blood pressure device will immediately protected, reducing the effectiveness of the measurement
The second software timing protection method does not take into account the degree of injury to the patient when the cuff pressure is high, and the defects of this method are particularly prominent in the neonatal mode

Embodiment Construction

[0068] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0069] According to the isothermal process of thermodynamics, it can be known that when the pressure increases, expansion occurs and external work is performed. The corresponding relationship between work and time is energy. Doing the same external work for different durations will produce different energies. In the measurement of non-invasive blood pressure, the external work of expansion shows that the cuff is inflated and squeezes the patient. The greater the pressure, the more the external work is, the more severe the patient is squeezed. The longer the time, the greater the energy generated, ...

Abstract

The invention belongs to the field of biomedical signal processing, and particularly relates to a pressure protection method and a pressure protection apparatus used in the non-invasive blood pressure measurement process. Energy value of pressure generated in a cuff serves as a reference for pressure protection so that different types of patients can be protected. By the pressure protection method, measurement effectiveness of the non-invasive blood measurement device can be improved effectively, and harm to patients due to energy variation caused by pressure difference can be considered. The pressure protection method has the advantages of higher flexibility and more effective protection and higher safety in measurement.

Description

technical field [0001] The invention belongs to the field of biomedical signal processing, in particular to a pressure protection method and device used in the process of measuring non-invasive blood pressure signals. Background technique [0002] Most noninvasive blood pressure measurements use the oscillation method. This method also requires blocking the arterial blood flow with a cuff like the traditional "Krotkoff sound method". However, in the deflation process, instead of detecting Korotkoff sounds, the pressure sensor detects the oscillation wave signal of the gas in the sleeve. These oscillating waves originate from the vibration of the arterial vessel wall. This oscillatory wave signal has a certain functional relationship with the arterial wall systolic pressure, diastolic pressure, and mean pressure. After the oscillatory wave signal is amplified and filtered, the envelope is detected, and then the corresponding relationship between the envelope and the systol...
