Embodiment 1

[0094] figure 2 It is a finger instrument for online acquisition of pulse wave of the present invention. In order to reduce the sensitivity and irritation of the human body to the skin, this embodiment uses reinforced natural rubber to make the rib lining of the finger sleeve, see Figure 5 ;The fingertip cover is made of ABS material, and there are notches with a width of 1.5mm and a length of 5mm on both sides, and a fixed LED opening with a size of 5mmX5mm at the upper end, and an opening of 8mmXmm at the lower end, which is used for fixing the photoelectric sensor. ,See Image 6. In this example, the wavelength of the LED is 840nm, and the infrared sensitive photoelectric sensor is used as the sensor of the pulse wave transmission sensor module. The signal obtained by the sensor is pre-amplified, and after two stages of amplification, the signal amplitude is about 1V. After AD conversion in the MCU, the digital signal is transmitted to the low-power Bluetooth module at ...

Abstract

The invention relates to a finger instrument for obtaining pulse waves online and a method for obtaining pulse wave peak shape parameters. The finger instrument includes a pulse wave sensing device, an electric signal control and processing device, a power source device, a fingertip sheath, a finger body sheath and a shell cover casing; the finger instrument is worn on one finger of a tested object, and the pulse wave sensing device and the fingertip sheath are placed on a fingertip; the finger body sheath is worn on the finger and forms an integrated structure with the shell cover casing to provide a loading space for other devices and the fingertip sheath; the pulse wave sensing device is electrically connected with the electric signal control and processing device, and the pulse wave sensing device and the electric single control and processing device are driven by the power source device to work. The finger instrument for obtaining the pulse waves is simple, reliable and capable ofquickly determining pulse wave signals of living bodies online in time, is used for further obtaining information about the heat rate and blood pressure and can be widely applied to wearable equipment and online monitoring equipment.

Description

technical field [0001] The invention relates to sensing technology and physiological parameter analysis and measurement technology, in particular to real-time online pulse wave extraction and analysis technology, especially to further obtain physiological parameters such as heart rate and blood pressure by obtaining continuous pulse wave information online, so as to determine the real-time physiological parameters of the tested object. parameters, to grasp the health status of the measured object in time; the present invention can be widely used to quickly, accurately, online, and instantly determine the physiological information such as the pulse wave of the analyzed organism. It can also help doctors and other professionals understand the individual's usual physiological conditions, so as to make more effective and targeted health diagnoses. Background technique [0002] With the improvement of living standards, people pay more and more attention to health. Although the t...
