Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of mouth and nose airflow detecting device and method.
Background technique
The channel of air-flow when the upper respiratory tract (including nasal cavity, nasopharyngeal cavity, pharyngeal cavity) of human body is eupnea.Nasal respiration is people
Body takes in the most important form of air, and nasal cavity can be filtered the air passed through, heat, humidifying, makes the sky into human body
Gas becomes cleaning, wet and warm；In addition, there are the variations that surface receptor can perceive air-flow and pressure for nose, and then adjust
The activity of Airway dilation flesh maintains epithelium healing open.Under normal physiological conditions, mouth breathing is only in special circumstances (such as movement, essence
Refreshing high-pressure etc.) under occur, to guarantee the uninterrupted air supply of body, nasal respiration has apparent physiology excellent human body
Gesture.It is some research shows that in the sleep procedure of not congestion, any sleep stage or body position, only about 4%
Gas is sucked by oral cavity, and nasal cavity sucking gas flow is far longer than the soakage of oral cavity gas.One epidemiological investigation
Show in Brazilian cities and towns crowd be up to 55% children (4-9 years old) there are mouth breathings.Most scholars think when in the upper respiratory tract
When a certain structure changes there are lesion or anatomic abnormalities (including adenoids, the hypertrophy of tonsils, chronic rhinosinusitis coexisting companion/no
With nasal polyp, allergic rhinitis, deviation of nasal septum, concha hypertrophy etc.) it is likely to result in congestion, so as to cause nasal airflow
Function is obstructed, and when reaching a certain level, human body can be adaptively mouth breathing mode diverted via nasal respiration mode.
Breathing pattern and the occurrence and development of quality of life, growth and development and disease are in close relations, how correctly to distinguish mouth
Breathing with nasal respiration and how mouth to mouth breathing and nasal respiration progress quantitative analysis be always clinician's bone of contention.Evaluate nose
Breathing and the most scientific method of mouth breathing are as follows: accurately measure the throughput of disengaging nasal cavity and oral cavity.Breathing relevant parameter is machine
The physical signs that weight is wanted plays an important role diagnosis, the treatment of disease in terms of respiratory system.Human body respiration monitoring is existing
For an important component of medical monitoring technique, accurate quickly measurement mouth and nose throughput has great meaning to clinical diagnosis and treatment
Justice.
Develop by years of researches, occurs a variety of mouth and nose air-flow detection methods on the market at present, it can according to measurement method
To be divided into the direct method of measurement and the indirect method of measurement.The direct method of measurement can directly measure mouth, nasal airflow amount, and the indirect method of measurement is then
It needs just obtain mouth, nasal airflow amount by complicated conversion calculating.The principle of direct detection mouth nasal airflow amount mainly has three classes
1. gas passes through the pressure detecting of mouth, nose when to breathing: mouth and nose throughput bring pressure being added in pressure with oral-nasal cannula and is passed
On sensor, the acquisition of signal is realized；2. detection of the air-flow to temperature change at mouth and nose: temperature sensor is placed in corrugated hose
On, human body exhales, air-breathing when the temperature change that generates can cause the resistance variations of sensor；3. the inspection that CO2 concentration changes at mouth and nose
It surveys: CO2 sensor is placed on mouth, at nose, measure the variation that respiratory air flow causes CO2 concentration.The indirect method of measurement mainly passes through survey
Mouth, nasal airflow amount is calculated by complicated conversion after amount chest and abdomen motion change.Using subject's splanchnocoel with respiratory movement
Periodically variable principle is mainly measured by pressure type detection method, impedance type detection method, respiratory inductive plethysmography etc.
Mouth, nasal airflow amount is calculated by conversion in total lung capacity.Pressure detecting method is pressure sensor to be attached to thorax abdomen or by two
Bar strain gauge waistband ties up to the characteristics of motion of chest, abdomen detection breathing bring splanchnocoel.Respiratory inductive plethysmography is
Clinically common breathing detection method, principle are the elastic ligatures for having insulated coil for two, are respectively wound around use
Person's thorax abdomen, the flexible of elastic ligature occur corresponding cyclically-varying with the respirometric rhythm and pace of moving things, cause coil around section
Product variation.When passing through high frequency pumping electric current in coil, the variation of sectional area leads to the variation of self-induction of loop, passes through detection coil
The variation of inductance can accurately trace out chest, abdominal respiration curve movement, it is hereby achieved that pneumatology physiological parameter abundant
(respiratory rate, tidal volume, inspiratory airflow and expiratory airflow etc.).Fields HW et al. uses inductance graphical method.First pass through breathing
Speed retouches meter instrument and measures the relationship of flow Yu chest and abdomen inductance, then nose connects nose cup and measures nasal airflow amount and chest and abdomen inductance at this time,
Replacement obtains general gas flow, is mutually kept to oral air flow.
It is held high currently, either direct mouth and nose respiration monitor or the mouth and nose respiration monitor measured indirectly have price
Expensive, instrument parts are more, and assembling/disassembly is time-consuming and laborious, complicated for operation, interfere greatly subject, the accuracy of measurement makes us matter
It doubts.Modern monitoring technology requires continuous monitoring, and need to have it is easy, noninvasive, accurate, stable, as far as possible reduction sense of discomfort and
The features such as without allergic reaction.Mouth and nose respiration monitor on the market is not up to conditions above at present, mouth and nose respiration monitor
Research and development need further research.
