Problems solved by technology

[0003] Heart rate is an important data for judging the functional status of the human body. The current heart rate collection is mostly carried out by means of skin contact detection equipment. This method will not only make patients feel uncomfortable, but also cause the infection of skin diseases

Embodiment

[0019] Such as figure 1 As shown, a pulse beating judging system using LEDs in the present invention includes: an LED light group array for emitting light; an adjustment module for the LED light group array to face the skin where the aorta exists subcutaneously; for receiving the skin reflected back The reflected light detection module of the light; the phase module used to detect the phase of the reflected light and the phase of the light emitted by the LED light group array; used to compare the phase of the reflected light with the phase of the light emitted by the LED light group array, and according to each The number of phase changes per minute yields a contrast module for the heart rate per minute. The adjustment module adjusts the irradiation angle of the LED light group array to 90°. The comparison module is used to set the initial number N, and assign a value to N, N=0; when the phase difference between the reflected light and the light emitted by the LED lamp array ...

Abstract

The invention discloses a pulse beating judging system using LEDs, comprising: an adjustment module for the LED light group array to face the subcutaneous aortic skin; a reflected light detection module for receiving the light reflected back by the skin; The phase module of the phase of the reflected light and the phase of the light emitted by the LED light group array; it is used to compare the phase of the reflected light with the phase of the light emitted by the LED light group array, and obtain the comparison of the heart rate per minute according to the number of phase changes per minute module. The pulse beating judging system using LEDs in the present invention is only detected by LED light arrays, and does not require equipment to be in contact with the skin, will not make patients feel uncomfortable, and will not cause infection of skin diseases. Long, the detection result will be affected when the environment changes, but the present invention detects the heart rate through the phase change, so when the light of the environment changes, the measurement result will not be affected, and the accuracy of the detection result is guaranteed.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a pulse rate judging system using LEDs. Background technique [0002] Heart rate refers to the number of heartbeats per minute of a normal person in a quiet state, also called resting heart rate, generally 60 to 100 beats per minute, which may vary among individuals due to age, gender or other physiological factors. Generally speaking, the younger you are, the faster your heart rate is, the heart rate of the elderly is slower than that of the young, and the heart rate of women is faster than that of men of the same age. These are normal physiological phenomena. In a quiet state, the normal heart rate of adults is 60-100 beats / min, and the ideal heart rate should be 55-70 beats / min. The heart rate of athletes is slower than that of ordinary adults, generally around 50 beats / min. [0003] Heart rate is an important data for judging the functional status of the human body. The current heart...
