Description

Technical Field

[0001] The present invention belongs to the technical field of blood pressure measuring instruments, and particularly relates to an intelligent blood pressure measuring instrument and its usage method. Background Art

[0002] With the continuous improvement of people's health awareness, blood pressure, as an important physiological index reflecting the human health condition, the accuracy and convenience of its measurement have received extensive attention. Intelligent blood pressure measuring instruments, with functions such as automatic measurement, data storage and transmission, have gradually become commonly used devices for home health monitoring and daily inspections in medical institutions. Currently, intelligent blood pressure measuring instruments on the market have many limitations in terms of structure and function. In terms of adaptability, the arm cylinder sizes of most blood pressure measuring instruments are fixed, unable to meet the needs of different users with different arm thicknesses. An arm cylinder that is too tight or too loose will cause a large deviation in the measurement results, affecting the accuracy of diagnosis; in terms of measurement accuracy, the sensor configurations of existing measuring instruments are relatively single, mainly focusing on the measurement of blood pressure and pulse, making it difficult to comprehensively evaluate cardiovascular health and being easily interfered by environmental factors such as temperature and humidity changes; in terms of operation convenience, the traditional manual adjustment method for the height of the arm cylinder is difficult to operate for people with limited mobility or the elderly, and the measurement process lacks intelligent guidance and feedback, resulting in a poor user experience. In addition, in terms of data transmission, some devices cannot ensure the stable upload of data in an environment with unstable network signals, restricting the application of remote health monitoring. Summary of the Invention

[0003] To solve the above technical problems, the technical solution adopted by the present invention is: an intelligent blood pressure measuring instrument, including an arm cylinder, a measuring component, a suspension structure, and a display component. The arm cylinder includes a cylinder shell, an airbag, and a contraction member. The contraction member includes an elastic plate. The head end and the tail end of the elastic plate are respectively fixedly connected with a plurality of uniformly spaced inserts. Slots are formed between adjacent inserts. The inserts at the head end of the elastic plate are inserted into the slots at the tail end of the elastic plate. This design enables the contraction member to be flexibly adjusted according to the thickness of different users' arms. By inserting the inserts into different slots, the circumference of the arm cylinder can be changed, greatly improving the adaptability of the measuring instrument. The airbag is located inside the cylinder shell, and the contraction member is located between the airbag and the cylinder shell. Both ends of the airbag are respectively fixedly connected to both ends of the cylinder shell. The airbag is connected to an air pump through a pipeline with a solenoid valve.

By measuring the time for the pulse wave to conduct from the heart to the measurement site and combining algorithms to calculate arterial elasticity parameters, more dimensional data can be provided for cardiovascular health assessment. At the same time, a temperature and humidity sensor is introduced to monitor the temperature and humidity of the measurement environment and the surface of the arm in real time, avoiding interference with the measurement results due to environmental factors. The data storage module uses a large-capacity flash chip, which can store no less than 500 groups of measurement data and supports data management classified by time and user.
