Description

The outdoor monitoring system of a kind of epileptic patient based on multisensor

Technical field

This utility model belongs to wireless sensor network technology field, is specifically related to the outdoor monitoring system of a kind of epileptic patient based on multisensor.

Background technology

" epilepsy " that namely epileptics is commonly called as or " sheep is insane crazy ", is the electric discharge of cerebral neuron paroxysmal abnormality, causes a kind of chronic disease of of short duration cerebral disorder.According to the sick data display of Chinese cri dernier cri, the overall prevalence of domestic epilepsy is 7.0%, and annual morbidity is have the activeness epilepsy prevalence of outbreak to be 4.6% in 28.8/10 ten thousand, 1 year.Estimate that about there is the epileptic of about 9,000,000 in China accordingly, the epileptic about 400,000 simultaneously newly increased every year, become in Chinese epilepsy the second largest commonly encountered diseases that department of neurology is only second to headache.Therefore, the outdoor monitoring system of a kind of epileptic patient based on multisensor is very important.

The cycle that epileptics is cured is longer, and the patient of about 50%-60% can fully recover through the treatment of 2-5, and patient cannot obtain the effective monitoring of hospital in whole therapeutic process, so the mortality rate of outdoor morbidity is higher.Developed country's commercial speeds such as America and Europe are very fast, and in health care, starting comparatively early, had ripe monitoring system substantially separately.The technical development of the health care aspect of China is rapid, and patient can well be treated within the hospital, but monitors this part out of doors, does not also form complete medical system.Dead because can not get treating timely after some patients suffering from sudden illness fall ill out of doors, this case is of common occurrence, therefore, adopts modern sophisticated technologies technology to carry out outdoor monitoring to patient and is extremely necessary.

The outdoor monitoring system of epileptics of the present utility model, the lateral-acceleration value of the six axle sensors not only human body used, further, the angle of human body rotates and balance, in order to determine the direction of putting upside down after patient falls ill and posture, and be equipped with condition sensor, calculate the physiological feature after the morbidity of patient.Whereby, can differentiate generally putting upside down and putting upside down after falling ill, improve the accuracy rate detected.

Utility model content

The outdoor monitoring system of epileptic patient based on multisensor provided by the utility model forms primarily of data acquisition module, data preprocessing module, radio receiving transmitting module, central control module, mobile reception end and terminal demonstration module.Six axle sensors are connected with A/D analog-digital converter input, outfan and the condition sensor of A/D analog-digital converter are connected in parallel, its signal output part is connected with data preprocessing module by bus, and the outfan of data preprocessing module is connected with wireless transmitter module; Described wireless receiving module is connected with the signal input part of central control module by USB interface; The outfan of central control module is connected with mobile reception end by wireless transmitter module, and described outfan is also connected with terminal demonstration module by hospital internal LAN simultaneously.

Data acquisition module is made up of the condition sensor of six axle sensors and 3 different accuracies.3 condition sensor are respectively: SON1205 heart rate pulse transducer module, SEN301 pressure transducer and HKT-09A body temperature trans.SEN1205 heart rate sensor stability is high, can instantaneous output heart rate waveform, can be used for monitoring the heart rate waveform in motion, and dynamically, static state is all very accurate; SEN301 micro pressure sensor measuring range is 0 ~ 40kPa/0 ~ 300mmHg, accurately up to ± 1%; HKT-09A body temperature trans measuring range is 20-50 DEG C, and precision is 0.1 DEG C.Six axle sensors collect the analogue signal that wearer produces, and are converted to digital signal by analog-digital converter, and then send to data preprocessing module together with the digital signal directly produced with condition sensor.Data preprocessing module is responsible for the lateral-acceleration value of human body in calculating six axle sensor and whether angular velocity of rotation breaks through threshold value, simultaneously according to the data gathered, calculates angle of inclination and the anglec of rotation of human body.Radio receiving transmitting module is responsible for the human body attitude data after by process and physiological data is sent to the central control module of hospital.Central control module primary responsibility carries out treatment and analysis to the body status data of patient, and result is sent to the mobile reception end of families of patients and the terminal demonstration module of hospital.The health of patient is shown to families of patients by mobile reception end primary responsibility, facilitates families of patients to understand the health of patient at any time.Terminal demonstration module is then responsible for the health of patient to be shown to medical worker, and the convenient epileptic patient to morbidity is taked to give first aid to timely.

Beneficial effect: this utility model system structure is simple, advanced technology, by the health adopting multisensor to monitor outdoor epileptic patient in real time chronically, while improving Monitoring Data speed and accuracy rate, data upload is carried out analyzing and processing to control module, and result is sent to mobile reception end and terminal demonstration module, for the life security of outdoor epileptic patient provides guarantee, alleviate the problem of inpatient bed deficiency, China's health care is had great importance.

Fig. 1 is structured flowchart of the present utility model.

Detailed description of the invention

This utility model is illustrated below in conjunction with embodiment.As Fig. 1, this monitoring system forms primarily of data acquisition module, data preprocessing module, wireless communication module, central control module, mobile reception end and terminal demonstration module.Six axle sensors are connected with A/D analog-digital converter input, outfan and the condition sensor of A/D analog-digital converter are connected in parallel, its signal output part is connected with data preprocessing module by bus, and the outfan of data preprocessing module is connected with wireless transmitter module; Described wireless receiving module is connected with the signal input part of central control module by USB interface; The outfan of central control module is connected with mobile reception end by wireless transmitter module, and described outfan is also connected with terminal demonstration module by hospital internal LAN simultaneously.

Described data acquisition module is made up of the condition sensor of MPU-6050 six axle sensor and different accuracy.Six axle sensors are made up of three axle accelerators and three-axis gyroscope, and three axle accelerators are responsible for gathering the acceleration change in human body all directions, and three-axis gyroscope responds to respectively to tilt forward and back, tilt and wiggly comprehensive multidate information.Condition sensor aspect: SON1205 heart rate pulse transducer module size is little, is quick on the draw, can be used for the heart rate waveform monitoring in moving, dynamic, static, all very accurate, and stability is high; SEN301 pressure transducer, cost is low, can provide accurate measured value, be widely used in electric sphygmomanometer; HKT-09A body temperature trans, is quick on the draw, detected temperatures wide ranges.
