Blood pressure measuring device and blood pressure recognizing device

Abstract

The invention relates to a blood pressure measuring device and a blood pressure recognizing device. The blood pressure measuring device comprises a sensor device, a pulse characteristic data extraction unit, a pressure data extraction unit, a storage unit and a blood pressure determination unit, wherein measured blood pressure data is not influenced by shrinkage and expansion of a living body. The blood pressure recognizing device comprises a blood pressure measuring device, a reference data storage unit, a comparing unit and a display device, wherein the display device is used for displaying output results which are compared by the comparing unit; and data representing the blood pressure is not displayed on the display device, or comparison results and the data representing the blood pressure are not displayed at the same time; the blood recognizing device is particularly applicable to non-medical persons and old people, and has the advantage of promoting patients to see a doctor. The blood pressure measuring device and the blood pressure recognizing device are particularly suitable for monitoring blood pressure continuously and dynamically.

Description

Technical field [0001] The present invention relates to a blood pressure measurement device and a blood pressure recognition device further expanded based on the blood pressure measurement device, including a pulse sensor used for the blood pressure measurement device and the blood pressure recognition device, and belongs to the field of medical equipment, health products, and sensor technology. However, It doesn't stop there. Background technique [0002] At present, the known devices for dynamically or continuously determining blood pressure by acquiring information on the surface of the arterial skin of a living body through a sensor device include: Notification No. The Chinese patent of "non-invasive continuous detection device for blood pressure"; its technical feature is to determine the blood pressure value by establishing the relationship function between blood pressure and pulse pressure; its shortcoming is that there is a need to first establish the relationship be...

[0002] At present, the known devices for dynamically or continuously determining blood pressure by acquiring information on the surface of the arterial skin of a living body through a sensor device include: Notification No. The Chinese patent of "non-invasive continuous detection device for blood pressure"; its technical feature is to determine the blood pressure value by establishing the relationship function between blood pressure and pulse pressure; its shortcoming is that there is a need to first establish the relationship between blood pressure and pulse pressure according to individual testers Complicated operation steps; in addition, in the actual continuous blood pressure monitoring, there are defects in the increase of measurement errors caused by the changes in the relationship between blood pressure and pulse pressure caused by the expansion and contraction of the user's limbs with body temperature, climate, exercise and other factors; secondly, there is also the defect of blood pressure The display characters are small, which is not conducive to the use of the elderly with poor eyesight, and is not conducive to the guardians other than the testers to observe at any time; in addition, it has the defect that it is not suitable for non-professionals. The reason is that: for ordinary people and the elderly Said that generally the detection of blood pressure just wants to know whether the blood pressure is normal, but the value of blood pressure cannot be explained and displayed in a complete sense for them, and some users even do not understand the change of blood pressure value in the process of continuous blood pressure monitoring , and even create a psychological burden. In a more serious situation, the user may take medication without authorization and delay the correct diagnosis at the hospital.
