Problems solved by technology

[0012] The purpose of the present invention is to provide a new sphygmomanometer and a method for measuring blood pressure using the sphygmomanometer. The sphygmomanometer can not only overcome the problems of traditional electronic sphygmomanometers, which are generally bulky and inconvenient to carry because they include cuffs, pumps and valves. disadvantages and is suitable for frequent blood pressure measurements without adding too much to the cost

Embodiment 2

[0066] The calibration process of the detachable unit 3 in the second embodiment can be found in Figure 7 The flow chart of the cuff blood pressure measurement is synchronized with the acquisition of physiological signals. During the calibration process, the detachable unit 3 needs to be inserted into the slot 208 of the main body part 2, as figure 2 shown. Before calibration, the user needs to select a calibration mode by pressing a button on the operation unit 308 . The first step of calibration is SA1, where the user needs to wrap the inflatable and deflated cuff 201 on the upper arm for cuff blood pressure measurement (eg, by oscillation method). Step SA2 is synchronized with SA1, and the user puts his finger on the sensor unit of the detachable unit 3 . One finger of the left hand is placed on the electrode 301, one finger of the right hand is placed on the electrode 303, and one finger of any hand is placed on the electrode 302, so that an electrocardiographic signa...

Abstract

The present invention provides one kind of non-invading blood pressure metering device and method. The non-invading blood pressure metering device includes one main part and one separable part, the main part includes cuff type blood pressure measurer, and the separable part connected electrically to the main part in separable mode includes one non-cuff type blood pressure measurer, and one control unit for controlling the blood pressure measurement with the main part and calibrating the non-cuff type blood pressure measurer based on the measurement result of the cuff type blood pressure measurer to determine the measured blood pressure value. The present invention makes it possible for the user to measure blood pressure with the cuff type blood pressure measurer or with the convenient and fast non-cuff type blood pressure measurer.

Description

technical field [0001] The present invention generally relates to electronic blood pressure measuring devices and methods, in particular to a non-invasive cuff-type blood pressure measuring device combined with a detachable non-cuff blood pressure measuring device based on pulse wave transit time or pulse wave transit velocity theory. Blood pressure measuring device and method. Background technique [0002] There are many different types of electronic blood pressure monitors on the market today, most of which use an inflatable and deflated cuff. A number of patents have been published on cuff-type blood pressure monitors, such as US Patents 4,625,277, 5,215,096, and 6,602,200. Many cuff blood pressure monitors use the oscillation method to measure blood pressure. When this method is used, an inflatable and deflated cuff needs to be wrapped around the user's arm, an electronically driven pump increases the pressure in the cuff, and a pressure sensor placed in the cuff can d...
