Description
Technical field
This utility model relates to medical instruments field, is specifically related to a kind of sleep breathe monitor based on the TFT liquid crystal display screen.
Background technology
Obstructive Sleep Apnea (OSAS) is a kind of disease with potential danger of sleep in the disease, and it refers to the Apnea that causes because of respiratory tract obstruction in sleep.Studies show that obstructive sleep apnea syndrome and hypertension, pulmonary hypertension, arrhythmia, ischemic heart desease, cerebrovascular accident are relevant, are the high risk factors of cardio-cerebral-pulmo angiopathy.Health according to hygiene department's issue is reported, and crowd's sickness rate of obstructive sleep apnea syndrome is 2%-4%, and over-65s old people prevalence reaches 20%-40%, and at Prevalence of Hypertension even up to 50%-90%.At present, China has the patient of the sleep apnea syndrome about 5,000 ten thousand, and along with China steps into the aging stage, monitoring, the diagnosis of sleep disease are further important.
At present, Polysomnography (PSG) is the goldstandard that internationally recognized sleep apnea syndrome diagnosis and treatment are estimated.But the parameter of monitoring is more when monitoring owing to use polysomnogram instrument, the sensor that adopts is very many, and these sensor majorities are attached to patient's head and face, that some sensations are than more sensitive position, so there are the shortcomings such as the monitoring of being in hospital, difficulty falling asleep, sensor are easy to come off in the patient in the process of monitoring, has a strong impact on sleep monitor effect and applying in basic unit/family.
And Portable sleep monitor has overcome these inferior positions of leading the sleep monitor instrument more, lead less, simple to operate, design is small and exquisite, easy to carry, expense is low, can not affect patient's sleep quality, can reflect daily real sleep state, be specially adapted to basic hospital and should not move or to the monitoring of the strong patient's of sleep environment dependency primary dcreening operation and observation of curative effect, monitoring result is true, accurately.
At present, be to lead sleep monitor to the judgement Main Basis of sleep disordered breathing clinically, and the sleep-respiratory that uses at present on the market monitoring volume is larger more, inconvenience is mobile, requires patient hospitalized to have a thorough examination, increases patient's financial burden; And electrode is numerous, affects easily patient's sleep quality, and testing result is had harmful effect.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of sleep breathe monitor based on the TFT liquid crystal display screen, efficiently solves the problems of the prior art, has increased each road physiological parameter of the in real time current collection of demonstration of TFT liquid crystal display screen.
This utility model is by the following technical solutions:
A kind of sleep breathe monitor based on the TFT liquid crystal display screen, comprise the electrocardiosignal filtering and amplifying circuit, blood oxygen module, sound of snoring signal amplification circuit filter, the chest signal amplification circuit filter, the abdominal part signal amplification circuit filter, the breath signal filtering and amplifying circuit, MCU, power supply and SD card, described electrocardiosignal filtering and amplifying circuit, blood oxygen module, sound of snoring signal amplification circuit filter, the chest signal amplification circuit filter, the abdominal part signal amplification circuit filter, the breath signal filtering and amplifying circuit, power supply is connected with MCU with S D card and is connected, wherein, also comprise a TFT liquid crystal display screen, described TFT liquid crystal display screen is connected with MCU.
As preferably, described based on also being provided with the USB interface chip on the sleep breathe monitor of TFT liquid crystal display screen; Described USB interface chip and SD link and connect.
The beneficial effects of the utility model are:
But this utility model recording respiration, blood oxygen, pulse frequency, electrocardio, chest exercise, abdominal exercise and seven parameters of the sound of snoring can be finished obstructive type time-out, maincenter type time-out, mixed type time-out, the low ventilation event analyzed.This utility model increases the TFT liquid crystal display screen on the basis of original Portable sleep breathe monitor, there not to be parameter display before solving, also record when taking care electric conductance on line, blood oxygen probe, each sensor or monitoring equipment and having internal fault will cause the data of a whole night mistake to occur like this.Each road physiological parameter that can the current collection of direct observation liquid crystal screen display before using the monitoring patient, each parameter all gather and begin record after normal again.
This utility model by the physiological parameter relevant with sleep procedure gathered, shows, record, analyzing and processing, it is the indispensable detection methods of sleep apnea clinical diagnosis and correlational study, for the monitoring of sleep disordered breathing disease provides effective means, be applicable to various big hospital and community (small towns) commune hospital, will further promote the prevention work of the multiple serious diseases such as the treatment of sleep disordered breathing disease and complication hypertension thereof, angina pectoris, myocardial infarction, arrhythmia.
