Description

Technical Field

[0001] The utility model relates to the field of physiological parameter detection, in particular to an array sensor and an array type physiological parameter monitoring device based on the superficial temporal artery. Background Art

[0002] As we all know, the normality of ECG, respiration, heart rate, blood pressure, blood oxygen and body temperature can almost directly judge a person's physical and mental health. Among them, ECG signals are generated by the electrical stimulation of the heart, and are signals obtained through the potential difference transmitted to various parts of the human body surface. The factors related to the ECG intensity collected from the body surface mainly include the number of myocardial cells (myocardial thickness), the distance between the position of the probing electrode and the myocardial cells, and the angle formed by the orientation of the probing electrode and the direction of myocardial depolarization. Due to the influence of the human body's physiological state and external factors, ECG signals will also show corresponding complex characteristics, and its P, Q, R, S, and T waves can directly reflect the working state of the heart. Heart rate and respiratory rate can also reflect the health of the body to a large extent. In a quiet state, the normal breathing rate of a normal person is 16 to 20 times per minute, and the normal value of heart rate is 60 to 100 times per minute. Exceeding this range usually means that the human body is abnormal or unhealthy. As for body temperature measurement, the body temperature is usually measured in the armpit, mouth and rectum. When measured in the armpit, the normal range of body temperature is 36 to 37℃. The body temperature will also change at different times of the day, but the fluctuation range is usually no more than 1°C. A low body temperature indicates that the person being tested has a poor constitution, poor immunity, or insufficient Qi and blood, and poor blood circulation. A high body temperature, or fever, is mostly due to inflammation caused by infection.

[0003] Research on blood pressure (BP) and blood oxygen (SpO2) began a long time ago at home and abroad. Among them, blood pressure measurement is earlier than blood oxygen measurement and the methods are more diverse, but accurate measurement is also more difficult.

[0004] Blood pressure refers to the lateral pressure exerted on the vascular wall per unit area when blood flows in the blood vessels. For blood pressure measurement, the most direct and accurate way is to place the sensor directly on the inner wall of the blood vessel for blood pressure measurement, but this method is invasive and not suitable for people's daily blood pressure testing. On March 8, 1817, French doctor Laennec began to use his utility model stethoscope for clinical diagnosis, which also became the most famous and now the "gold standard" method - auscultation. Doctors obtain the corresponding systolic and diastolic pressures by listening to the changes in the sound of the pulse under the cuff. Later, with the development of science and technology, electronic cuff sphygmomanometers appeared. They are generally measured at the brachial artery of the left and right hands. Compared with the auscultation method that requires the participation of doctors, electronic sphygmomanometers are easy to use and have a smaller difference in accuracy than auscultation (generally within ±5mmHg). It has become the mainstream of blood pressure measurement today, and with the arrival of the "mercury restriction order", electronic cuff sphygmomanometers have a trend of replacing auscultation. However, the measurement method of electronic cuff sphygmomanometers also determines that they are not suitable for long-term blood pressure measurement. Therefore, in recent decades, people have begun to study non-contact, wearable blood pressure monitoring. This type of blood pressure measurement uses people's basic research on blood flow, blood vessels and pulse theory to indirectly measure blood pressure. Among them, measuring blood pressure based on pulse waves has become the first choice for indirect blood pressure measurement methods.

[0005] Regarding the pulse wave measurement method, the previous pulse wave measurement generally uses piezoelectric sensors to obtain the pulse wave at the corresponding position. Although the forms are diverse and mature, the strict measurement position and anti-interference performance (body movement) will also cause large errors in the precise piezoelectric sensor. In addition, the method of relying on pressure sensing will always cause pressure on the measured blood pressure part, which will cause discomfort after wearing for a long time, and is not suitable for long-term non-sensitive blood pressure measurement.

[0036] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0037] In this embodiment, Figure 1-3 As shown, an array-type physiological parameter monitoring device is provided, which can be worn in front of the ears on both sides of the human body using a special structure in actual application. It can achieve long-term health monitoring, and the data can be transmitted to each mobile terminal via wireless communication. Specifically including:

[0038] Two measuring components, the measuring components include a packaging shell 10, a flexible transparent packaging component 11, an array sensor 1, an ECG electrode 2, a data transmission component and a microprocessor; the array sensor 1, the ECG electrode 2 and the data transmission component are all connected to the microprocessor; the flexible transparent packaging component 11 is used to seal and package the array sensor 1 and the ECG electrode 2, and the flexible transparent packaging component 11 and the wireless communication component are fixed on the packaging shell 10. The data transmission component is preferably a wireless antenna 6.

[0039] The fixing component includes an arc-shaped elastic rod 4 and a hard package 3. Two measuring components are respectively arranged at the two ends of the arc-shaped elastic rod 4, and form an ear-hook structure with the arc-shaped elastic rod 4 to be hung on the superficial temporal artery. The arc-shaped elastic rod 4 is provided with a hard package 3 in the area near the measuring component. A power supply, Bluetooth and a microprocessor are installed in the hard package 3. The power supply is used to power the Bluetooth, preferably a lithium battery, and the Bluetooth establishes communication with the wireless antenna 6 to send the data sent by the wireless antenna 6 to a remote terminal. The arc-shaped elastic rod 4, the hard package 3 and the measuring component together form a bone conduction earphone structure. The arc-shaped elastic rod 4 can provide appropriate elastic force to achieve a comfortable wearing experience on the basis of fixing the sensor.

[0040] Specifically, the array sensor 1 comprises: a mounting portion, on which a plurality of mounting cavities distributed in an array are arranged, and the mounting cavities are isolated from each other by photoelectric isolation elements; the mounting cavity comprises a plurality of detection light source cavities and a receiving cavity;

[0041] A plurality of different types of detection light sources, the detection light sources correspond to the detection light source cavity one by one and are installed in the detection light source cavity.

[0042] Among them, in a preferred embodiment, the detection light source includes the red / infrared light source 9 and the green light source 7; the receiving device includes an infrared thermal radiation receiver 5 and a photoelectric receiver 8; the detection light source cavity includes a red / infrared light source 9 cavity and a green light source 7 cavity, and the receiving cavity includes an infrared receiving cavity and a green light source 7 receiving cavity;

[0043] There are two layout modes of the array sensor 1. The first layout mode is as follows: Figure 3 As shown:

[0044] The red / infrared light source 9 cavity, the infrared receiving cavity, the green light source 7 receiving cavity and the green light source 7 cavity are arranged in sequence along one direction, and are respectively used to install the red / infrared light source 9, the infrared thermal radiation receiver 5, the photoelectric receiver 8 and the green light source 7. The photoelectric receiver 8 is used to receive the reflected light formed by the red / infrared light source 9 and the green light source 7 on the measurement object.

[0045] The second layout is as follows Figure 4 As shown:

[0046] The receiving cavity includes a first receiving cavity, and the first receiving cavity is arranged with an infrared receiving cavity and a photoelectric receiving cavity along a first direction; the infrared receiving cavity is used to install the infrared thermal radiation receiver 5, and the photoelectric receiving cavity is used to install the photoelectric receiver 8. The red / infrared light source 9 cavity, the first receiving cavity and the green light source 7 cavity are arranged in sequence along a second direction; the first direction intersects with the second direction.

[0047] In a preferred embodiment, the first direction and the second direction are perpendicular to each other.

[0048] The measurement principle of this scheme is as follows: the red / infrared light source 9 is part of the blood oxygen sensor, which uses reflective red / infrared dual-color light to obtain the direct current signal of hemoglobin and oxygenated hemoglobin, and then directly obtains the blood oxygen saturation from the hemoglobin and oxygenated hemoglobin content reflected by the direct current signal. The principle comes from Lambert-Beer's law. The green light source 7 is part of the blood pressure sensor, which is implemented in the form of green light reflective PPG. The original pulse wave signal involved in the measurement method will be processed through an independent filtering circuit, AD conversion module and micro data processing module, and the blood pressure will be measured after obtaining the data that meets the standard of the blood pressure measurement algorithm. Blood pressure and blood oxygen share an ambient light sensor (photoelectric receiver 8). When performing actual measurement, the light source is controlled by the control circuit to obtain the electrical signal of the corresponding physiological signal.

[0049] Heart rate and breathing signals are obtained by combining ECG signals and pulse wave signals with algorithms. After obtaining real-time physiological parameters, the microprocessor integrates and packages all data and sends them to the mobile terminal via the wireless transmission module. To facilitate the application of the utility model, the wireless transmission module adopts the Bluetooth communication protocol and a short-range, low-power micro Bluetooth module. Due to the particularity of its circuit, the utility model independently packages it to avoid electromagnetic interference.

[0050] It should be noted that all algorithms in the present invention are prior art, and reference may be made to the prior application with patent application number 202311228134.4, which is not the focus of the present invention. The focus of the present invention is on the layout setting of the array sensor 1 and how to fit the array sensor 1 more firmly to the superficial temporal artery.

[0051] The structure of the entire array sensor 1 is divided into the array sensor 1, the flexible package and the hard shell outer package. The reason for using the flexible transparent package is that it has good light transmittance and physical compatibility, does not affect the acquisition of the photoelectric signal and can fit the skin well. The array sensor 1 is encapsulated in the flexible transparent package and isolated from the subsequent signal processing circuit.

[0052] As for the array sensor 1 itself, since the principle of collecting ECG signals is different from that of collecting other signals, the electrodes 2 of ECG signals are isolated from the photoelectric sensors such as blood pressure and blood oxygen. In the integrated photoelectric sensor part, the utility model uses a relatively high black fence structure to separate the green light source 7, the ambient light sensor and infrared thermal radiation receiver 5, and the red / infrared light source 9 to prevent them from affecting each other. The black fence structure used is a flexible material that can fit the skin well to form a dark and enclosed space.

[0053] The microprocessor is an embedded microprocessor based on the ARM architecture Cortex-M4F core of Texas Instruments, which has excellent analog and digital signal processing functions. It has 512KB flash memory and 256KB RAM, which can meet the needs of real-time data storage and processing; the power supply used is a micro rechargeable lithium battery; the Bluetooth module is a low-power ultra-small Bluetooth module based on the Bluetooth 5.1 protocol.

[0054] The present invention adopts a single-lead method to collect ECG signals, so it is necessary to combine at least two groups of array sensors 1 in front of the ear (or other) parts. The number of combined array sensors 1 can be increased according to actual application requirements to achieve health monitoring of more parts and higher accuracy.

[0055] During the measurement, if Figure 4 The black fence structure shown will fit the skin to realize four enclosed spaces, namely the red / infrared light source 9 cavity, the infrared receiving cavity, the green light source 7 receiving cavity and the green light source 7 cavity. The micro data processor will issue control instructions to the three light sources respectively. When measuring blood pressure, only the green light is turned on and the red / infrared light source 9 is turned off. At this time, pulse wave monitoring can be performed. After obtaining a high-quality pulse wave signal, the blood pressure can be obtained according to the algorithm. When measuring blood oxygen, the red / infrared light source 9 will be turned on and off respectively to obtain corresponding direct current and alternating current signals, which directly reflect the content of hemoglobin and oxygenated hemoglobin, and the blood oxygen level can be calculated based on this. When measuring body temperature, since the body temperature measurement uses the infrared thermal radiation naturally emitted by the human body, in order to avoid artificial interference, the infrared light source needs to be turned off before real-time body temperature monitoring can be performed. When measuring blood pressure, blood oxygen and body temperature, ECG monitoring can be performed simultaneously. The difference between it and the blood pressure and blood oxygen measurement principle makes them have no influence on each other. As mentioned above, the heart rate and respiratory signals are obtained by combining the ECG signal with the algorithm.

[0056] like Figure 5The figure shows the principle structure diagram of the utility model. Both the ECG and blood pressure sensing parts need to convert the measured signals into digital signals through a 16-bit AD module. The 16-bit AD conversion module can perform high-precision AD conversion on analog signals, and the impact on the original signal can be ignored. After the converted digital signal is processed by the MCU, the corresponding physiological information is calculated. Body temperature and blood oxygen content are directly characterized by the size of the electrical signal, so they are directly calculated by the microprocessor. Finally, the MCU packages the measured ECG, blood pressure, blood oxygen, respiration, heart rate and body temperature data and sends them to the mobile terminal via Bluetooth. For the subject wearing the utility model, they can understand their health status in real time by connecting the mobile phone to Bluetooth.

[0057] like Figure 6 As shown, there is another implementation method of the measuring component in the utility model, that is, a measuring component is attached to both wrists and ankles, and electrocardiographic physiological parameters are collected using limb dual leads.

[0058] In actual measurement, Figure 2 The structure shown can fix a pair of array sensors 1. To improve the measurement accuracy, this product can combine three or more array sensors 1 according to specific needs and add corresponding algorithms to achieve higher accuracy and more physiological monitoring of more parts. As for ECG measurement, since the source of its signal is the potential difference of ECG signals in different parts, more array sensors 1 mean more limb leads or chest leads, which can obtain more accurate ECG signals. For blood pressure measurement, after eliminating the blood pressure difference caused by gravity in different parts, more accurate blood pressure measurement results can also be obtained by measuring blood pressure with different array sensors 1. In addition, in order to make the measurement results more accurate, the algorithm used needs to be calibrated according to the static measurement data of the subject (the subject is in a static state for more than 30 minutes) before the measurement. At the same time, since the age, height, gender, etc. of the subject are closely related to his physiological signals, this information needs to be entered before the test to allow the sensor to calibrate the algorithm.

[0059] In summary, the utility model places the acquisition position of human physiological parameters on the superficial temporal artery, which can well meet the comfort and high-precision requirements of wearable measurement; the integrated array sensor can simultaneously measure electrocardiogram, blood pressure, blood oxygen, heart rate, body temperature and respiratory signals, and can fully understand one's own physical health status; the use of a special structure allows the sensor to be close to the superficial temporal artery, and real-time blood pressure measurement can be performed even in motion, making long-term real-time high-precision blood pressure measurement possible; in actual application, under the premise of close contact with the skin surface and without affecting comfort, health monitoring can be performed in different parts according to needs by combining different numbers of array sensors 1, which can further improve detection accuracy.

[0060] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
