Embodiment Construction

[0028] figure 2It is a block diagram of a high-precision sphygmomanometer 200 of the present invention, which is used to measure a user's blood pressure. The high-precision sphygmomanometer 200 includes a main air tank 210, an auxiliary air tank 220, and a pressurizing device 230 , a decompression device 240 , a pressure detection device 250 , a heartbeat detection device 260 , a control device 270 , and a display unit 280 .

[0029] The main air channel 210 applies pressure to the user's wrist or arm. The auxiliary air tank 220 is connected to the main air tank 210 , and there is an air valve 225 between the auxiliary air tank 220 and the main air tank 210 to release air from the auxiliary air tank 220 to the main air tank 210 .

[0030] The main air channel 210 may be provided in a wrist / arm strap 290 for wrapping around a user's wrist / arm.

[0031] The pressurizing device 230 is connected to the main air tank 210 and the auxiliary air tank 220, so as to inject air into t...

Abstract

The invention discloses a high-precision blood-pressure meter and a blood-pressure measuring method. Pressure is applied to the wrist or arm of a user through a main air duct. An air valve is arranged between an auxiliary air duct and the main air duct so as to release air in the auxiliary air duct to the main air duct. Air is fed into the main air duct and the auxiliary air duct through a pressurizing device so that the pressure is applied to the wrist or arm of the user. A depressurizing device is arranged on the main air duct. A pressure detection device is used for detecting the pressure of the main air duct and outputting a pressure value. A heartbeat device is used for detecting a ripple voltage signal corresponding to heartbeat due to the impact of blood inside the aorta of the user. A control device is used for controlling the depressurizing device to release the pressure in the main air duct and controlling the opening of the air valve according to the ripple voltage signal, so that air is released from the auxiliary air duct to the main air duct.

Description

technical field [0001] The invention relates to the technology of a sphygmomanometer, especially a sphygmomanometer that releases air from an auxiliary air tank to a main air tank to accurately detect systolic and diastolic blood pressure. Background technique [0002] According to statistics, the population structure in the future will move towards aging and declining birth rate, and the average age of family members will gradually increase. Cardiovascular disease will be one of the important topics for future prevention and treatment. In order to prevent cardiovascular diseases at an early stage, a sphygmomanometer is an indispensable basic detection device at home. [0003] The sphygmomanometers used in the market today are divided into manual pump sphygmomanometers, audio sphygmomanometers, and oscillation blood pressure (oscillation blood pressure) sphygmomanometers. Manual-pump sphygmomanometers include an armband, hand pump, vent valve, mercury manometer, and stethos...
