Electric sphygmomanometer with discoloration display

Abstract

The invention relates to an electric sphygmomanometer with discoloration display, which comprises a shell, a power supply unit, a pressure measurement unit, an A / D conversion unit, a microprocessor, a display unit, a first light-emitting unit and a second light-emitting unit. The surface of the shell is provided with a first light-transmitting area and a second light-transmitting area, the first light-emitting unit is arranged on the inner side of the shell and corresponds to the first light-transmitting area, and the second light-emitting unit is arranged on the inner side of the shell and corresponds to the second light-transmitting area; and the microprocessor further comprises a data storage unit and a judgment unit, is respectively connected with the first light-transmitting unit and the second light-transmitting unit and used for indicating the first light-transmitting unit and the second light-transmitting unit to emit light with different colors according to a judgment result of the judgment unit. Through the respective color displays to high blood pressure and low blood pressure, the invention is more beneficial for users to clearly know about the levels of the high blood pressure and the low blood pressure per se; and the light-transmitting areas are positioned on the outer shell of the shell, thereby the space of a display screen is saved, the circuit is simple and the cost is saved.

Description

technical field [0001] The invention relates to an electronic sphygmomanometer, in particular to an electronic sphygmomanometer with color-changing display. Background technique [0002] Currently known electronic sphygmomanometers mostly directly display the blood pressure measurement results in digital form on the display screen for the blood pressure measurement results, or provide prompt lights of different colors to remind the measurer whether the blood pressure is normal or dangerous, although it can play a certain role. However, due to the small size of the indicator light and the weak brightness of the light source, it is not easy for the elderly and users with poor eyesight to distinguish the color of the indicator light. [0003] The patent document with the publication number JP1160530 discloses an electronic sphygmomanometer, which compares the measured blood pressure value with the WHO standard, performs blood pressure classification judgment, and highlights the...

[0002] Currently known electronic sphygmomanometers mostly directly display the blood pressure measurement results in digital form on the display screen for the blood pressure measurement results, or provide prompt lights of different colors to remind the measurer whether the blood pressure is normal or dangerous, although it can play a certain role. Warning function, but due to the small size of the indicator light and the weak brightness of the light source, it is not easy for the elderly and users with poor eyesight to distinguish the color of the indicator light

[0003] The patent document with the publication number JP1160530 discloses an electronic sphygmomanometer, which compares the measured blood pressure value with the WHO standard, performs blood pressure classification judgment, and highlights the corresponding area of ​​the display screen according to the judgment result to achieve warning. Function, although this warning method can realize blood pressure classification display, but because it is only highlighted in the corresponding area, the warning effect of a single color is not strong

[0004] The patent document with the publication number JP2004121632 discloses an electronic sphygmomanometer, which judges the blood pressure classification and displays it as a columnar area on the LCD screen; there are still products on the market that are based on the blood pressure classification judgment and are displayed in different colors through the backlight of the LCD screen ; Although it can realize blood pressure classification and play a warning role, it only provides color warnings for the comprehensive judgment of high and low voltages, and requires a large display panel, which takes up space on the display screen, and the circuit structure is complex and the cost is high
