Problems solved by technology

However, these two methods are for the diagnosis of patients in the middle and late stages of the disease, and they are invasive examinations, which are not only expensive, but also have certain risks, and are not suitable for routine screening. Therefore, non-invasive early detection of arteriosclerosis, Early diagnosis and early control have become the themes of contemporary medical science and education and social development, and are also an important topic proposed by the society to medical researchers

Embodiment 1

[0027]Example 1: The basic structure of the non-destructive detection instrument for human arteriosclerosis is as follows figure 1 As shown, the non-destructive detection instrument for human arteriosclerosis is connected to the microcomputer through the USB interface, and then the heart sound sensor and the electrocardiogram sensor are connected to the host box of the non-destructive detection instrument for human arteriosclerosis through a dedicated wire, and the microcomputer can be connected to a local printer. And network printers, the measured data provides network retrieval. The subject was placed in a supine position, exposing the subject to be tested. When the system is turned on, place the heart sound sensor on the apex outside the thorax and press it down with a light sandbag.

Embodiment 2

[0028] Embodiment 2: The operation of detecting the human body is as follows figure 2 As shown, two cuffs are fixed on the left and right upper arms, and the other two cuffs are fixed on the left and right ankles. The blood pressure sensor is located in the main box and is connected to the cuff through the air guide tube. The blood pressure sensor converts the air pressure of the cuff into a corresponding electrical signal. Fix the ECG sensor on the wrist with a wrist clip.

Embodiment 3

[0029] Embodiment 3: as image 3 The sensor site shown is against skin that has been applied with water or conductive paste.

[0030] Before starting the test, the testee needs to take a few deep breaths to be calm and breathe evenly. At the beginning of the test, the air pump inflates the four cuffs. After about 10 seconds, the device automatically recognizes the highest systolic blood pressure of the person being tested, and adds 10 to 20mmHg of pressure on the basis of the predicted highest systolic blood pressure, and then stops the inflation. , and then deflate, so that the person to be tested will not feel uncomfortable. After the sensor collects signals, transmits, amplifies, filters, analog-to-digital conversion and data analysis, the detection work is all over in about 3 to 5 minutes. The stored data can be recalled at any time for testing report printing or data retrieval, and can also be used for remote data sharing through network components.

Abstract

The invention relates to an instrument based on pulse transmission velocity and a pulse wave theory. The instrument comprises an arteriosclerosis detector host box, four sets of cuffs and rubber conduits, two sensors for detecting electrocardiographs and conducting wires as well as auxiliary wrist clips, a sensor for detecting heart sound signals, a microcomputer and a printer. The instrument is characterized in that: the electrocardiograph sensors and the heart sound sensor are connected with respective preprocessing modules respectively, then the preprocessing modules are connected with respective primary filtering modules, and finally the primary filtering modules are connected with a singlechip respectively; and the singlechip is also connected with a blood pressure signal amplification module and the microcomputer, and the blood pressure signal amplification module is connected with a blood pressure sensor. The hardware cost, the volume and the cost are reduced; and the instrument can be used for hospitals, communities and home environments. The instrument has a friendly software interface, is easy to operate, has multiple functions, and can store diagnostic reports under the condition that the printer is not arranged.

Description

technical field [0001] The present invention relates to electromechanical devices, in particular to an instrument or system based on the theory of pulse wave transmission speed and pulse waveform, which measures the time of pulse wave transmission and analyzes the pulse by placing sensors on the relevant parts of the limbs of a supine human body or any designated part. Combined with the brachial-ankle blood pressure index to judge the arterial blockage and use the measurement parameters of the heart sound sensor to evaluate the arterial elasticity level of the human body, at the same time measure the systolic blood pressure, diastolic blood pressure, mean pressure, pulse pressure, heart rate, and waveform rise time of the limbs , Pulse wave volume recording, ECG waveform, heart sound waveform, systolic time interval, etc. Background technique [0002] In recent years, with the in-depth understanding of human vascular lesions, people have gradually realized that vascular wall...
