Dynamically calibrated blood pressure reference value electronic sphygmomanometer

Abstract

The invention is an electronic sphygmomanometer that dynamically calibrates for a real-time standard blood pressure reference value, which is determined based on the objective condition of human blood pressure fluctuation influenced by various factors such as age, date and time of measurement, and establishes age/blood pressure reference value, date/blood pressure reference value and time/blood pressure reference. The value database, or through mathematical operations, obtains the real-time standard blood pressure reference value under the specific conditions of the subject's age, test date, and test time, and calibrates it as a benchmark for judging the abnormality state of the real-time blood pressure measurement value. This improves the ability of the sphygmomanometer in producing an accurate judgement of the subject's blood pressure, and reduces the margin of error for false positive tests or false negative tests.

[0030] 1. Age data display of the measured object,

[0031] 2. Date, time display,

[0034] 5. Abnormal blood pressure information sound and light tips, battery power display.

[0035] The specific embodiments of the invention will be described in detail below with reference to the accompanying drawings. As shown in FIG. 1, the present invention is composed of six parts, specifically including a blood pressure (heart rate) data acquisition unit, a measured subject information data input unit, a database (age/blood pressure reference value, date/blood pressure reference value, time/blood pressure reference value), an MCU, a display and a power supply. The solid line represents the frame part of existing electronic sphygmomanometers. The information data input unit and database of the measured object are shown by the dashed line frame and are contents of the invention new to existing sphygmomanometers.

[0036] FIG. 2 is a schematic diagram of a display unit according to the invention. The dashed line frame portion is a content of the invention new to existing sphygmomanometers, specifically the real-time standard blood pressure reference value data display and age data display. Age data can be input through a touch screen or a key input method (conventional technology design, not shown on FIG. 2) to adjust the age data to match the age of the measured subject. Then the MCU can use the currently displayed data as the age data of the measured subject.

[0037] The real-time standard blood pressure reference data is displayed in a specially designed single-sided arrow-shaped graphic frame. The arrow points to the middle position of the blood pressure warning bar, and the image indicates the meaning of the standard blood pressure reference value to show the blood pressure status in terms of (ab)normality.

[0038] The clock display (circuit) is a standard configuration of an existing electronic sphygmomanometer, providing date (day, month, year) and time data, including a MCU-driven clock unit, an independent clock unit independent of the MCU, and a wireless (e.g. WIFI) timing clock unit. The date and measurement time data of the invention can be obtained through the above three methods. When the blood pressure monitor starts the blood pressure data acquisition process, the MCU obtains the real-time clock data to dynamically calibrate the blood pressure reference value with the date and measurement time data.

[0039] FIG. 3 is a flowchart of the dynamic calibration procedure of the standard blood pressure reference value according to the invention. The program flow is as follows: after the power of the sphygmomanometer is turned on, the system (MCU) is initialized, and the default age data is the median age (36-40 years old). The default standard blood pressure reference value is 120/80..fwdarw.The MCU collects the date and time data displayed on the system clock..fwdarw.According to the date and time displayed, the standard blood pressure reference value would be adjusted by data obtained from a date/blood pressure reference value database composed of a mathematical function or curve (see FIG. 5) and a time/blood pressure reference value database composed of a mathematical function or curve (see FIG. 6). Age data modification. If yes, the age data is used to modify the standard blood pressure reference value displayed, which would be obtained from an age/blood pressure reference value database composed of a mathematical function or curve (see FIG. 4). If not, maintain the age data as the default value, and maintain the standard blood pressure reference value as corrected by date and time data. That is, when the condition data of the measured subject's age, measurement date, and measurement time are obtained, the system (MCU) dynamically calibrates the real-time standard blood pressure reference value data of the measured subject through database search or mathematical operations, driving the display to display the real-time standard blood pressure reference value data.

[0040] In addition to the real-time standard blood pressure reference data through three conditions of age, date and time dynamic calibration procedure, the real-time blood pressure measurement procedure of the electronic sphygmomanometer of the present invention is the same as the existing electronic sphygmomanometers. After the real-time blood pressure measurement data is generated, the MCU compares and calculates the real-time blood pressure data with the real-time standard blood pressure reference value data to determine the (ab)normality state of the measured subject, and drives the display to display the real-time blood pressure data and blood pressure abnormality information of the measured subject.
