Pulse and red blood cell concentration monitoring instrument and method

Abstract

The invention discloses a pulse and red blood cell concentration monitoring instrument which comprises a finger pinching device. An opening is formed in one end of the finger pinching device, a cavity is formed in the finger pinching device, and an infrared light source and a photoelectric detector are oppositely arranged on the upper surface and the lower surface of the cavity respectively. The finger pinching device is connected with a storage and operation device and a display device in sequence. The finger clamping device clamps the finger pad of a testee, after the infrared light source irradiates the finger, original light intensity signals are transmitted, the photoelectric detector receives the original light intensity signals and converts the original light intensity signals into electric signals to collect data within the pixel range, the electric signals are stored in the storage and operation device for storage and processing, and obtained pulse data and red blood cell concentration data are displayed through a display device. According to the pulse and red blood cell concentration monitoring instrument, the signals are collected through the photoelectric detector based on a CMOS camera, detection sensitivity and precision are high, the light intensity signals are processed based on a signal intensity frequency domain modulation method, dicrotic waves can be reduced and even eliminated, and therefore the measurement result is improved. The operation is simple, calculation complexity is greatly reduced, and storage space is saved.

Description

technical field [0001] The invention relates to the field of medical electronic detection and pulse wave signal detection and processing, in particular to a pulse and red blood cell concentration monitor and method. Background technique [0002] With the increase of people's pace of life and work pressure, the incidence of cardiovascular diseases such as heart disease is increasing, and the detection of cardiovascular diseases has attracted more and more attention. The pulse contains important information about the cardiovascular condition of the human body and is closely related to many diseases. Therefore, the cardiovascular condition can be judged by measuring the pulse. [0003] At present, there are mainly pressure, pulse diagnosis, electrocardiographic and photoelectric methods for measuring pulse. The pressure method is usually realized by a pressure sensor made of a pressure sensitive element, which has the advantages of complex process, high manufacturing cost, heav...

[0003] At present, there are mainly pressure, pulse diagnosis, electrocardiographic and photoelectric methods for measuring pulse. The pressure method is usually realized by a pressure sensor made of a pressure sensitive element, which has the advantages of complex process, high manufacturing cost, heavy equipment, not light and inconvenient. Disadvantages such as easy false positives and false positives

Pulse diagnosis type, traditional Chinese medicine pulse condition diagnosis technology is the effective application of pulse measurement in traditional Chinese medicine, but it is greatly affected by human factors, and the measurement accuracy is not high; The chest of the measured person is measured by the electrocardiographic method to measure the heart beat of the measured person to measure the pulse rate of the measured person. The method detects the pulsation of the blood vessels of the subject to measure the pulse rate of the subject. The latter mainly uses the method of photoplethysmography. There are dicrotic waves in the process of photoplethysmography measurement, which interferes with the measurement results and leads to inaccurate heart rate measurement results. The blood red blood cell concentration can be used to judge medical diseases. Clinically, the blood red blood cell concentration can be used as an important basis for diagnosing adrenal hyperfunction. Diagnosis and treatment, it is not only used clinically, but also widely used in testing the physical fitness of athletes and other aspects. At present, there are few monitors that can measure pulse and red blood cell concentration at the same time to meet the needs of patients. Therefore, providing a pulse It is very necessary to have a monitor and a method that have accurate measurement results and can simultaneously measure red blood cell concentration
