The gateway node stores or displays the ECG or other physiological parameters, or transmits the ECG or other physiological parameters to the main server or the monitor terminal via the local area network or the Internet or the mobile network, so that local/remote monitoring is performed.

Description

Wireless multi-parameter near-real-time real-time monitoring system

Technical field:

The utility model relates to a wireless multi-parameter near-distance real-time monitoring system based on wireless ECG or other parameter collecting nodes and a body area network, belonging to a wireless sensor, a wireless sensor network, a body area network, an electrocardiogram and other parameters. Remote real-time monitoring area. .

technical background:

The collection of human physiological and pathological information is an important part of the doctor's diagnosis and treatment work in hospitals. The parameters related to vital signs, such as ECG, blood pressure, respiration, pulse, body temperature and oxygen saturation, are important monitoring for patients in ICU CCU and other wards. Indicators are also the main monitoring indicators for high-risk groups outside the hospital.

I. Demand outside the hospital:

1. The cause of sudden death is the first place in cardiovascular disease, accounting for more than half. At present, due to the lack of effective monitoring, most of the cardiac arrests have died outside the hospital, accounting for 60%-70%, of which 1/2-3/4 died at home, and 8-12% died at work. % died in public places.

2. The occurrence of other non-fatal cardiovascular events is also highly random, ranging from several times a day to several times a year. The frequency, occasion, and time of occurrence cannot be predetermined. The duration of the event is several seconds to several hours. The reason for the occurrence is also unclear because there is no ECG information at the time of the attack. After the event, the hospital will obtain the information, which may not help determine the cause.

2. Needs in the hospital: Cardiovascular patients in the hospital are mostly acute, critical, and critically ill patients, including those in the Department of Cardiology and other departments that need to monitor vital signs. They need real-time monitoring of physiological parameters such as ECG, respiration, pulse, Body temperature, blood oxygen saturation.

3. Need to monitor the object

1. General subjects: a. Patients with high-risk cardiovascular and cerebrovascular diseases: 500,000 new myocardial infarctions per year in China, 2 million patients with myocardial infarction, 4 million heart failures, 8 million atrial fibrillation, and sudden death due to severe arrhythmia About 500,000 people; 200 million people with hypertension, 200 million people with dyslipidemia, more than 30 million people with diabetes, 240 million people with overweight, 70 million people with obesity, and 350 million people with smokers. b. High-risk patients with other diseases. c. Seniors over 60 years old

2. Special custodial objects: special people such as the word Navigator, pilots, athletes, soldiers, etc. or animals that need to be protected or studied.

4. Due to the above requirements, near-remote monitoring is widely used, but the traditional monitoring equipment has many pipelines connected, that is, there are lead wires or other pipelines from the sensor to the signal collector. The equipment is too bulky and has high energy consumption. It is difficult for the monitoring object to receive near-distance monitoring in a long-term and comfortable manner. In order to solve the above problems, the current remote multi-parameter monitor has been greatly improved, but the ECG sensor has a lead wire connection before the signal collector (or to the non-mobile device), and other physiological parameters are collected to the signal processing. There are also pipelines, and most portable ECG monitors have a limited number of leads, such as:

1. The device with many ECG lead wires, such as the remote ECG monitoring system disclosed by the patent CN200977158Y, is used for in-hospital and external communication, and realizes the remote communication between the ECG acquisition module (ECG monitor) and other components of the system, with 12 leads. ECG collection capability, but the ECG acquisition module and the electrode are still wired, resulting in:

(1) Patients in the hospital, especially those in the ICU or CCU, are connected to many pipelines, and more than 70% are connected to the electrode wires or pipelines of the multi-parameter monitor, which affects the basic life activities and comfort of the monitoring object, such as the condition Indoor and outdoor activities in the situation: turning over, sitting up, urinating, bedside activities, affecting the psychological state of the patient, combating the confidence of their recovery, from psychological to physiological affect the recovery of the patient, it is also difficult for patients to receive long-term monitoring The important reason.

(2) Patients outside the hospital or other people with special needs (including indoor and outdoor, high-risk groups in the wild) can not be long-term, unaffected, real-time, due to more lead lines in work, life, study and other activities. Comprehensive monitoring of ECG and other physiological parameters.

2. Portable devices with less ECG lead wires, such as CN201005693Y, CN101474068A, "Study on wireless sensor-specific wearing monitoring system" and "Research on remote monitoring system based on wireless sensor network", the disadvantages are as follows:

(1) Only 3~6 leads in the chest, this ECG is not a standard ECG, no important limb leads, signal collection is not comprehensive, only for simple arrhythmia monitoring, can not include common myocardial infarction, angina pectoris, heart rhythm The dysfunctional diagnosis, the diagnostic value is greatly reduced, can not reach the World Health Organization and the American Heart Association advocated - using 12-lead real-time continuous synchronous ECG to monitor the heart, the heart replacement page can be measured in time (Article 26) Changes in ECG before the onset of the disease, early prevention of heart attack and serious consequences. If the limb lead line is increased, it is difficult to monitor the walking of the subject, and the problem like the patent CN200977158Y is bound to occur.

(2) The integration degree is not high. The ECG acquisition and analysis module is made of integrated circuit board (PCB), which is about 20-40 times larger than the mobile phone T-F card. The device is still large and has room for reduction.

(3) The power consumption is large, the monitoring time is short, and it is less than 24 hours.

E.g:

(1) The wearable ECG electrode vest with data recording device disclosed in the patent CN200920089699, miniaturizes the ordinary Holter, has no monitoring function, the data recording device is placed in the pocket, and the 6 electrodes are on the vest by the electrode line and the data. The collection device is connected, the model of the vest and the user

'The material is fit, the vest is tight, so that the electrode is in close contact with the body; because the electrode and electrode wire are sewn together with the vest, the vest can not be washed and washed normally, only lightly washed, up to 30 times, can not be given For personal use; because it is impossible to predict how many times a patient will use it, there may be a possibility that it will be discarded when it is used less than 30 times; there are 3-6 leads on the chest, and there are no critical 6 limb leads, ECG display It's not a standard ECG, the diagnostic value is greatly reduced; the tight vest is also difficult to comfort because of tightness.

(2) Patent CN201005693Y discloses a wireless ECG acquisition and GPS positioning device for use outside the hospital and outdoors. ECG acquisition and patient positioning communication are realized, and remote monitoring can be performed. However, there is still a line between the ECG acquisition module and the electrode. The monitoring is limited to the chest, and there are no critical 6 limb leads.

(3) The portable wireless ECG monitoring device disclosed in the patent CN101474068A is used in and out of the hospital to realize portable monitoring. However, due to its use of the Zigbee wireless transmission module, the transmission distance is limited (about 100 m), and is connected to the hospital peripheral monitoring device through the USB module. Then access the Internet for remote monitoring; but because there is no remote communication module (such as GPRS), it can not be used outside the hospital, ward or home, beyond Zigbee wireless transmission range; its electrodes are wired, Only 3 leads on the chest.

(4) "Research on Wireless Sensor Special Wear Monitoring System" and "Research on Remote Monitoring System Based on Wireless Sensor Network" proposed wireless transmission of monitoring nodes such as ECG, blood pressure, respiration, pulse, body temperature and oxygen saturation. , many pipelines have been reduced, but the ECG node is a reference to the "Three-lead remote ECG monitoring system with S3C2410" method, that is, using three wired chest electrodes to connect ECG monitoring nodes, not based on " The body network of the fully wireless sensor network can be remotely monitored by ECG. The disadvantage is that the ECG electrode is still wired, limited to 3 leads in the chest, no standard ECG machine and Holter function.

In short, there is currently no one that can affect the pathological or physiological activities of the monitoring object, no lead wire, miniaturization, low power consumption, long-term monitoring, melting near remote ECG monitoring, portable electrocardiograph, 24-hour dynamic electrocardiograph And other parameters monitoring and other functions as a whole based on wireless ECG or other physiological parameters collection nodes and wireless body area network 3-18 lead ECG and other physiological parameters of the real-time near-remote monitoring system.

Beneficial effects:

1. The lead-free line of the acquisition node or the portable gateway node, the activity of the monitored object and the increase of comfort

The monitoring object can carry out near-distance monitoring only with the acquisition node or the portable gateway node, and the node data transmission is wireless, and the constraint of the pipeline to the monitoring object is removed; the hospital monitoring object, such as ICUXCCU: can at least reduce the ICU\CCU patient body. % of the pipeline; reduce the psychological pressure of the patient, can also enable the patient to complete various rehabilitation training if the condition allows, which is conducive to the recovery of the disease; the external monitoring object of the hospital can also be conveniently fixed in the need to collect ECG information and Other physiological parameters of the object - an ordinary patient and other special monitoring objects.

2. High integration, miniaturization and portability of nodes:

The chips used in the acquisition node and gateway node are synthesized based on CMOS technology, which is very small, ranging from 3mm to 7mm. Then the chip chip is packaged in micro-package technology (without PCB, such as the patent CN101474068A portable module has an overall size of 3cm). (Width) *4cm (length) *lcm (thickness)), only 10xl0x5mm after the acquisition node package, only one dime size; only 12x12x5mm after the gateway node is packaged (excluding GSM\GRPS\GPS, only one dime size) ) A 26x24x5mm (including GSM\GRPS\GPS only one dollar coin size), side plug button battery (l l.6x5.4mm, 605mA), acquisition node and gateway node miniaturization, people The interface module is miniaturized and portable, easy to use indoors and outdoors, and is easy to accept for objects that require long-term monitoring. It is also a prerequisite for long-term monitoring. With the miniaturization of CMOS chips and the maturity of MEMS chips, it is expected that the acquisition nodes will be made lxlxlmm in the future. For example, Smart dust used by the US military can be as small as a TF card.

3. Full lead monitoring:

Because the collection node and the portable gateway node are wireless, highly integrated, miniaturized, and portable, the number of leads to be monitored by the monitoring object is easily increased, especially the limb lead, which can be like a conventional electrocardiogram in 3-18. The selection of the collection nodes between the leads makes the collected ECG data more comprehensive and more diagnostic.

4. Single node with low power consumption and strong vitality:

(1) The chips of the collection node and the gateway node all use ultra-low power consumption, high integration, and programmable chips. These chips have multiple working modes, and the sleep state consumes only a few microamps, and a button battery is The collection node and the indoor gateway node can supply power for one day to several tens of days. The power consumption of a single node is very low. A large capacity battery of a mobile phone can supply the outdoor indoor dual-purpose gateway node for several days, which is one of the keys to long-term monitoring. ;

(2) There are a variety of communication modes that allow for significant power savings, including:

When the A collection node and the short-distance gateway node are simultaneously on the monitoring object, the transmission distance of the programmable acquisition node can be 5m, so that the power consumption of the collection node is the lowest, and the data of the collection node is received by the short-distance gateway node within 5m. Send data to the monitoring terminal within 100m or plug in the human interface module (non-portable computer, such as home PC) with embedded RF communication module.

The B collection node is on the monitoring object. When the short-distance gateway node is on the human-machine interface module, the gateway node can obtain the power supply of the human-machine interface module through the USB interface, especially when inserting or embedding on the non-portable computer, the power supply can be infinitely long. Time, such as: When the monitoring object is in ICU\CCU\ or at home, wear the collection node with a distance of only 5m, and transmit the data to the indoor multi-parameter monitor (home PC+ indoor gateway node can be composed), which is the lowest power consumption. One of the combinations.

C. For example, Smart dust, a MEMS chip with solar self-charging, will be market-oriented and civilized, and will greatly extend its vitality.

System components and communication costs are low:

(1) The acquisition node and the gateway node composed of the CMOS-based chip module are low in cost;

(2) The human-machine interface module of this system is widely used at present; the short-distance and long-distance distance gateway nodes are easy to access the USB module, and the human-machine interface module for household or unit can increase its utilization rate;

(3) The near and long-distance transmission of the system uses open protocols and networks, such as: Remote: IP over PPP and TCP IP; Proximity: Zigbee\Simplici; Remote transmission does not need to be re-routed, and wired transmission costs are increasingly low. Free coverage of mobile network (free wireless Internet access in Beijing North Fourth Ring Road and South Second Ring Road, wireless coverage in other parts of the country, 3G and 4G communication also laid the foundation for improving communication efficiency, Zigbe _e \ for short-range transmission The Simplici RF communication module, which forms a wireless body area network and a wireless LAN, saves the cost of transmission.

6. The ECG information or other physiological parameters monitored or collected are longer:

The chips of the collection node and the gateway node are small, low-power, durable, and can be replaced at any time. In addition, the collection node and the gateway node are wireless, the system components and the communication are low-cost, the monitoring object is easy to receive long-time monitoring, and the data can be stored in the portable Dedicated embedded terminal\Mobile\PDA expansion card\ or send it to the main server at any time, because the expansion card (expanding card storage capacity is increasingly powerful, some have reached 36G) and the computer's hard disk can be exchanged without limit, in theory The collection of ECG information can be infinitely long, which means that the monitoring time is almost unlimited.

7. Both hardware and software are high:
