Embodiment Construction

[0030] The sphygmomanometer of the present invention is used figure 1 The functional block diagram representation.

[0031] The sphygmomanometer consists of a wrist cuff 1, a wrist cuff pressure detection means 2 connected to the wrist cuff 1 through an air hose 1b, a pressurization means 3, a fast exhaust means 4a and a slow exhaust means 4b, and these means 2, 3 and 4a connected to the control section 8 constitutes. This sphygmomanometer is also provided with an operation switch 6 for sending instructions to the control unit 8 .

[0032] In addition, the control section 8 is selectively connected to pressurization number setting means 9 .

[0033] Wristband 1, such as figure 2As shown, it is a bag used to pressurize the subject's wrist and tighten the blood vessels. The pressurizing means 3 is specifically a pressurizing pump, which delivers air to the wristband 1 to exert pressure on the wristband. Quick exhaust means 4a is to release the pressurized air in the wrist...

Abstract

A sphygmomanometer, wherein the mode of pressurization on the cuff for measuring a blood pressure is varied according to whether a time for continuously pressing an operating switch (6) is longer or shorter than a set time, and whether the operating switch (6) is released before the blood pressure reaches a preset pressurizing value or at any time point after the blood pressure exceeds the set pressurizing value.

Description

technical field [0001] The invention relates to an electronic sphygmomanometer which determines the blood pressure value by detecting the pulse pressure of each pulse superimposed on the cuff pressure (Cuff pressure). Especially a sphygmomanometer that detects the pulse wave and determines the blood pressure value during the gradual decompression process once the wrist cuff is pressurized. Background technique [0002] When blood pressure is measured several times with a sphygmomanometer, it is known to set the pressure value of the wrist cuff based on the highest blood pressure value measured last time at the time of the second and subsequent measurements. [0003] attached Figure 10A And attached Figure 10B , is a graph showing the change of pressure in the wrist cuff (cuff pressure) and pulse wave data during blood pressure measurement, with Figure 11 It is a time chart showing the method of pressurizing the wrist cuff with the existing sphygmomanometer to measure bl...
