Embodiment approach

[0064] In a preferred embodiment of the present invention, the sensing device 1 further includes a light emitting diode and a photodetector.

[0065] Light-emitting diodes and photodetectors are fixed on one side of the bed 4, see image 3 shown. In this way, the photoplethysmography signal can be collected from the user's finger very conveniently.

[0066] The processor 2 can be fixed on the device or integrated in personal belongings such as watches, PDAs or mobile phones.

[0067] According to the pulse wave transmission theory, the pulse wave transit time can be used for the blood pressure measurement of the device of the present invention. The pulse wave transit time can be obtained according to the user's electrocardiographic signal and photoplethysmographic signal. In the embodiment of the present invention, the characteristic point of the electrocardiographic signal may preferably be the apex of the R-shaped wave on the electrocardiographic signal. In the embodimen...

Abstract

The invention relates to and discloses a measurement device for physiological parameters, which comprises a sensing device, a processor and a seat. The sensing device is fixed on the seat to collect physiological signals of users; the processor is connected with the sensing device to receive the physiological signals collected by the sensing device and to deal with the corresponding physiological parameters obtained by the physiological signals. The invention provides the measurement device for physiological parameters, which can simplify operating procedures, facilitate the convenient for the users operation and possess good generality.

Description

technical field [0001] The invention relates to a measuring device, in particular to a physiological parameter measuring device. Background technique [0002] The monitoring of physiological parameters can provide users with instant information feedback. In particular, the monitoring of changes in key physiological parameters reflecting the function of the cardiovascular system can provide immediate information feedback for patients with cardiovascular and cerebrovascular diseases, which is of great significance. [0003] The detection device of electrocardiogram signal generally adopts the sensor mode of three leads or twelve leads at present. For example, if the three-lead method is adopted, the wire electrodes need to be fixed on two wrists and one ankle, and the physiological signals of the human body are collected through the wires, and the corresponding physiological parameters are generated through processing by the processor. At present, the detection device of ECG...
