Description
[technical field]
The present invention relates to medical electronics apparatus, pick off and circuit design field, be specifically related to a kind of sleep-respiratory state monitoring apparatus based on the piezoelectric cable pick off.
[background technology]
Along with development of science and technology, the raising of living standards of the people, people are to sleep physiology, pathology pay attention to day by day.Show through medical research: the people of snoring probably suffers from " apnea syndrome ".Apneic definition is meant that respiratory tract stops air-flow and reaches more than the 10s.Like night snoring and with intermittent apnea more than 30 times, each time out surpasses can be diagnosed as " apnea syndrome " more than the 10s.This is a kind of potential fatal disease.Upper respiratory tract obstruction causes carrying out property anoxia, acidosis, dyspnea when being characterized in sleeping.Cause symptoms such as drowsiness, dizzy, headache on daytime, hypomnesis, weak, delay of response, sleep behavior be unusual.Long-term suffer from " apnea syndrome " can cause hypertension, arrhythmia or sudden death.
The doctor uses nighttime sleep to breathe multinomial physiological monitor in the diagnosis sleep-apnea often at present; The sleep cycle of record a whole night, situations such as the record of signals such as the number of times that shoals comprising asphyxia and breathing, kenel, anoxia index, number of times, Electrocardiographic variation, mouth and nose chamber air-flow, the motion of breast abdominal respiration, ear-lobe blood oxygen, the number of times of snoring.Though these apparatus measures are more accurate, need wear multiple instrument on one's body, also must in specific hospital, operate just and can measure by the professional person, very inconvenient, and also influence patient's sleep easily, so be not suitable for doing secular monitoring.And such instrument costs an arm and a leg, and is less compliant in family and uses.
[summary of the invention]
Main purpose of the present invention is to provide a kind of state monitoring apparatus of sleep-respiratory cheaply, can monitor the respiratory characteristic parameters such as respiratory frequency, asphyxia number of times and asphyxia time of user under sleep state.
For realizing above-mentioned purpose; The present invention inserts many piezoelectric cable pick offs in the thin pad with the mode parallel connection of bending; User need not adhere to anything on one's body, only need lie in above the thin pad, and the pressure that the respiratory movement of user produces changes and changes the signal of telecommunication into by piezoelectric transducer; Handle through signal processing module, obtain parameters such as respiratory frequency, asphyxia number of times and asphyxia time.Under the situation that warning function is opened, surpass setting value if find the asphyxia time, just alarm device can give the alarm.User is inserted into memory interface with SD card or USB flash disk, can preserve the breathing state Monitoring Data at a plurality of nights.These data are copied on the computer, handle and analyze, can obtain sleep-respiratory statistic result by computer software.These statistical results have reflected the user sleep-respiratory state every night and the sleep-respiratory change of state situation at a plurality of nights.
The invention has the beneficial effects as follows:
Adopt the sensing component of piezoelectric cable pick off, guaranteed the accuracy and the accuracy of monitoring of respiration as the sensing human body respiration.The piezoelectric cable pick off is distributed in whole thin pad with the lines mode of bending, and portion can monitor breathing in any position, and human body need not adhere to anything, and is little to the user restriction.This monitoring device is in light weight; Very portable, can monitor user sleep-respiratory state in real time and have warning function, can also preserve the sleep-respiratory status data at a plurality of nights and the analysis that takes statistics; According to The result of statistics; Common user can be known the sleep quality of oneself, and the respiratory disorder patient can understand the own ill order of severity, and the respiratory disorder patient who is receiving treatment can judge the therapeutic effect of oneself.In outage, open air or be inconvenient to connect electricity etc. in particular cases, user can be supplied power with battery.
[specific embodiment and description of drawings]
The application's characteristic and advantage will be through embodiment, in conjunction with the accompanying drawings.
Fig. 1 is the system block diagram of this sleep-respiratory state monitoring apparatus, forms by approaching pad 1, piezoelectric cable pick off 2, signal processing module 3, alarm device 4, memory interface 5, battery 6, display screen 7 and keyboard 8.When carrying out monitoring of respiration with this device, user only need lie on the thin pad, when user is breathed; The breast abdomen all can produce periodic deformation; This faint deformation of piezoelectric cable pick off sensing, and change it into the signal of telecommunication, handle and analyze through signal processing module 3 again; Obtain respiratory characteristic supplemental characteristics such as respiratory frequency, asphyxia number of times and asphyxia time, these data can be kept in the SD card of receiving on the memory interface 5 or USB flash disk automatically.Under the situation that warning function is opened, if abnormal conditions take place, alarm device will give the alarm.
Fig. 2 is a kind of structure chart of piezoelectric cable pick off.We adopt the piezoelectric cable pick off of the U.S. smart amount company, and it is the form that piezoelectric polymer is processed into coaxial cable, and piezoelectric when pick off is under pressure or be stretched, will produce charge signal between heart yearn and shielding line.Pick off has two lead-out wires, the inside be holding wire, the outside be shielding line.This piezoelectric cable transducer sensitivity is high and have favorable linearity output, is suitable for very much the monitoring of human life signal.
Fig. 3 is the sketch map of having inserted the thin pad of piezoelectric cable pick off.In thin pad the inside, 6 piezoelectric cable pick offs are installed, every piezoelectric cable pick off bends twice.For fixation of sensor, sew on tightly along the edge of pick off, put into flexible materials such as Cotton Gossypii or sponge in the gap.During practical implementation, the size of thin pad, the radical of pick off, bending number of times, bending spacing etc. can require suitably to adjust according to reality.
Fig. 4 is one embodiment of the present of invention, has shown the monitoring of respiration result in user on May 7th, 2010.Use the present invention, user can be preserved Monitoring Data such as respiratory frequency, asphyxia number of times and asphyxia time every night, and data through software processing and analysis, just can be checked monitoring of respiration data every night easily.
Fig. 5 is an alternative embodiment of the invention, has shown the result of the sleep-respiratory statistic analysis in user in May, 2010.User is suffered from for " apnea syndrome " of receiving treatment, and has preserved the sleep-respiratory status monitoring data in May, and these data through computer software analysis, are obtained asphyxia number of times, the statistical result of asphyxia time of this month.Statistical result shows that the user asphyxia number of times in May, asphyxia time reduces gradually, and therapeutic effect is better.
As stated, just can realize the present invention preferably, can not assert that practical implementation of the present invention is confined to these explanations.All equalizations of doing according to content of the present invention change and modify, and are all contained by claim of the present invention scope required for protection.
