Description

The nearly realtime remote monitoring system of wireless multiple parameter

Technical field:

This utility model relate to a kind of based on wireless electrocardio or and the nearly realtime remote monitoring system of wireless multiple parameter of other parameter acquisition node and body area network, belong to the nearly remote live monitoring of wireless senser, wireless sensor network, body area network and electrocardio and other a plurality of parameters field.

Technical background:

The collection of physiological pathology of human body information is an important ring of doctor's diagnosis and treatment work in the hospital, concern the parameter of vital sign, as electrocardio, blood pressure, breathing, pulse, body temperature, blood oxygen saturation then is ICU CCU and other ward patient's important monitor control index, also is the main monitor control index of high-risk group outside the institute.

One. the demand outside the hospital:

1. Cu Si reason accounts for the first place with cardiovascular disease, accounts for over half.At present, owing to lack effectively monitoring, the sudden cardiac arrest overwhelming majority is died from outside the hospital, accounts for 60%-70%, and wherein 1/2-3/4 dies from the family, 8-12% dies from work position, 6% die from the public place.

2. the generation of other non-sudden death cardiovascular event, very strong randomness is also arranged, for several times/day-for several times/do not wait in year, frequency, occasion, the time of taking place all can't pre-determine, several seconds persistent period to a few hours of incident are not waited, the reason that takes place also since do not stay outbreak at that time ecg information and can't determine that incident finishes the data that examination in hospital afterwards obtains, may not help to assign a cause for an illness.

Two. the demand in the hospital: cardiovascular patient mostly is urgency, danger, patient with severe symptoms in the hospital, comprise that intracardiac section and other each sections need monitor the patient of vital sign, need the various physiological parameters of real-time monitoring, as electrocardio, breathing, pulse, body temperature, blood oxygen saturation.

Three. need guardianship

1. the general high-risk cardiovascular and cerebrovascular disease patient of object: a.: China annual New Development myocardial infarction 500,000 people, now suffer from myocardial infarction 2,000,000 people, heart failure 4,000,000 people, atrial fibrillation 8,000,000 people are owing to severe arrhythmia about 500,000 people that die suddenly; Existing hyperpietic 200,000,000, dyslipidemia patient 200,000,000, diabetics more than 3,000 ten thousand; Overweight person 2.4 hundred million, the overweight people 7,000 ten thousand, and the smoker 3.5 hundred million.B. the high-risk sufferer of other disease.C. surpass 60 years old old people

2. special guardianship: special population such as spaceman, pilot, athlete, soldier or need protection or study the animal of observation.

Four. because above demand, nearly long distance monitoring is used very widely, but traditional custodial care facility all has many pipelines to link to each other, the line of leading or other pipeline are promptly all arranged from the pick off to the signal picker, equipment is too heavy, energy consumption is higher, causes guardianship to be difficult to for a long time, cosily accept nearly long distance monitoring.In order to overcome the above problems, nearly long-range multi-parameter monitor has been done very big improvement at present, but EGC sensor before signal picker (or before non-mobile device) all has the line of leading to connect, other physiological parameter collects signal processing also pipeline, and most portable electrocardiogram monitor are led several limited, as:

1. the many equipment of cardiac diagnosis lead-line, as the disclosed remote electrocardiogram monitor system of patent CN200977158Y, be used for inside and outside the institute, realized the telecommunication of electrocardiogram acquisition module (electrocardiogram monitor) with other assembly of system, the 12 electrocardiogram acquisition abilities of leading are arranged, but still be wired between electrocardiogram acquisition module and electrode, cause:

(1) patient in the institute, especially the patient of ICU or CCU, many pipelines have been connected from head to foot, be electrode wires or the pipeline that is connected to multi-parameter monitor more than 70%, influenced basic vital movement of guardianship and comfort level, as the indoor and outdoor activity under the state of an illness permission situation: stand up, sit up, defecation, bed be other movable, influenced patient's mental status, having hit the confidence of its rehabilitation, all influence patient's rehabilitation from psychology to physiology, also is the major reason that patient is difficult to accept long-time monitoring.

(2) outside the institute patient or other have special requirement person's (comprising indoor and outdoor, open-air high-risk group) in activities such as work, life, study since more lead line and can't long time, monitor electrocardio and other physiological parameter insusceptibly, in real time, all sidedly.

2. the few portable set of cardiac diagnosis lead-line, as CN201005693Y, CN101474068A, " wearing monitor system research based on wireless senser is special " and " based on the remote monitoring system research of wireless sensor network ", shortcoming is as follows:

Only front 3-6 leads, this electrocardiogram neither standard cardioelectric figure, no important limb lead, signals collecting is not comprehensive, only can be to simple arrhythmia monitoring, can't be to comprising common heart infarction, angina pectoris, arrhythmia level diagnosis, diagnostic value is had a greatly reduced quality, do not reach that World Health Organization (WHO) and american heart association advocate---use the 12 real-time continuous electrocardiogram monitoring of cardiac that lead, the electrocardio that can measure in time before the heart attack changes, prevention of cardiac outbreak in early days and the serious consequence that causes.As increase the limb lead line, then the monitored object walking is also very difficult, the problem the same with patent CN200977158Y certainly will occur.

(2) integrated level is not high, and electrocardiogram acquisition, analysis module are to be made by surface-mounted integrated circuit (PCB), and the 20-40 times of the about mobile phone T-F card of size installs still greatlyyer, and the leeway that dwindles is arranged.

(3) power consumption is big, and the monitoring time is short, how less than 24 hours.

For example:

(1) the wear-type electrocardioelectrodevice vest of the disclosed band data recording equipment of patent CN200920089699, with common Holter microminiaturization, the function of not having monitoring, data recording equipment is placed in the pocket, 6 electrodes are linked to each other with data acquisition unit by electrode wires on vest, vest model and user's stature adapt, and vest is close-fitting, contact with the tight of health in order to electrode; Because electrode and electrode wires and vest are sewed together, vest can't routine be unpicked and washed, and only with fine laundering, uses at most 30 times, also can't be personal to second; Owing to can't expect that a patient uses how many times, be about to its depleted possibility in the time of may occurring using much smaller than 30 times so; The front has 3-6 to lead, and does not have 6 very crucial limb leads, and that electrocardiogram shows is not standard cardioelectric figure, and diagnostic value greatly reduces; Jerkin is also because close-fitting vest is felt embarrassed to mention comfortable.

(2) disclosed wireless electrocardiogram acquisition of patent CN201005693Y and GPS positioner are used for reaching outside the institute outdoor.Realized electrocardiogram acquisition and patient location communication, can do long distance monitoring, but still wired between electrocardiogram acquisition module and electrode, monitoring is confined to chest, does not have very crucial 6 limb leads.(3) the disclosed portable wireless cardiogram monitor of patent CN101474068A, institute is inside and outside to be used, realized portable patient monitor, but because it uses the Zigbee wireless transport module, transmission range limited (about 100m), link to each other by the peripheral custodial care facility of USB module and hospital, insert Internet then, the realization remote monitoring; But because no telecommunication module (as GPRS) makes it to use in place outdoor, that exceed the Zigbee radio transmission range far away in hospital, lesion or family; Its electrode is a wired connection, and only lead in front 3.

(4) " wear monitor system research " and " based on the remote monitoring system research of wireless sensor network " has proposed electrocardio based on wireless senser is special, blood pressure, breathe, pulse, body temperature, the wireless transmission way of monitoring nodes such as blood oxygen saturation, many pipelines have been reduced, but wherein cardioelectric monitor node is a way of having quoted " realizing three remote electrocardiogram monitor systems that lead with a S3C2410 " literary composition, promptly connect the cardioelectric monitor node with three wired precordial electrodes, be not based on the body area network of the sensor network of " wireless fully ", can remote electrocardiogram monitor, shortcoming is that electrocardioelectrode is still wired, be confined to 3 in chest and lead, the electrocardiograph of no standard and the function of Holter.

In a word, at present neither one can not influence guardianship pathology or physiological activity, does not fully have the line that leads, microminiaturization, low-power consumption, can long term monitoring, functions such as molten nearly remote electrocardiogram monitor, cardioscribe, 24 hr Ambulatory EKG Monitoring machines and other parameter monitoring be one based on wireless electrocardio or and the 3-18 of other physiological parameter acquisition node and the wireless body area network near remote monitoring system in real time of electrocardio and other physiological parameter that leads.
