Description
Technical field
The present invention relates to a kind of respiratory effort identification equipment and the device and method of sleep apnea monitoring, more particularly to
Measurement for wing of nose action signal, and judge whether subject carries out respiratory effort with wing of nose action signal.
Background technique
Sleep apnea syndrome becomes the research hotspot of medical field in recent years, according to " U.S.'s sleep medicine meeting
(AASM) interpretation standard ", sleep apnea event can be divided into obstructive type apnea, maincenter type apnea and mixed type and exhale
Inhale pause；When apnea occurs, there is the respiratory effort for continuing or enhancing during entire air-flow missing, then it is assumed that be
Obstructive type apnea；If respiratory effort is not present during entire respiratory air flow missing, then it is assumed that be maincenter type apnea；If
Breathe no more effort but event latter half respiratory effort of apnea start-up portion restores, then it is assumed that is that mixed type breathing is temporary
Stop.
The goldstandard of monitoring respiratory effort is to be tested by Esophageal Pressure, but Esophageal Pressure test is a kind of intrusive test,
Easily cause subject uncomfortable and is difficult to carry out whole night.Currently, the mode instead of Esophageal Pressure monitoring respiratory effort of extensive utilization is
Impedance caused by thorax abdomen respiratory movement or inductance variation are measured, such as breathing is carried out by chest and abdomen piezo strip or chest electrode piece and is exerted
The monitoring of power.
Currently, sleep analysis monitor (PSG) is the goldstandard for clinically diagnosing sleep apnea syndrome, it is most of
The monitoring still moved by chest and abdomen when PSG is tested is to determine whether there is respiratory effort, and PSG can be same in sleep whole night
When monitoring human body multi-channal physiological and more monitoring result parameter can be calculated.But in practical applications, lead sleep more
Monitoring device volume is big, portability is poor, system complex, cumbersome, and tester needs could be complete under the assistance of medical staff
At test；Wearing comfort is poor during the test by tester, and hospital environment greatly influences the sleep quality of patient.
Existing Portable sleep monitoring of respiration equipment is generally integrated multiple sensors in one, generally includes nasal airflow prison
Module, ECG module, chest and abdomen motion module are surveyed, such form inevitably causes subject wears uncomfortable, and especially nasal airflow is supervised
Survey and both chest and abdomen motion modules for monitoring respiratory effort are placed in the different parts of subject, and cable is various, using easypro
Suitable sense is low.
Qian Hong's jade proposes bones of the body lingualis or the wing of nose when nasal respiration in " research of obstructive respiration sleep suspend and nasal airway resistance "
The enhancing when myoelectricity of flesh includes relatively nasal obstruction and mouth breathing；Li Xiaoming points out normal person's nose in " the current limliting segment of nose air flue "
With respiratory movement isometric contraction occurs for musculus pterygoideus, maintains dilator naris air flue to stablize with this constant, in vestibulum nasi in addition to wing of nose tissue
Resistance to deformation effect is outer, and compliance relies primarily on wing of nose flesh and changes with transmural pressure power difference in respiratory and occur quick anti-
Activity is answered to adjust, respiratory movement amplitude is shown as and deepens to increase, the contraction movement of wing of nose flesh also enhances therewith.
Summary of the invention
Present invention solves the technical problem that being to provide a kind of sleep breath monitoring device intensive, usage comfort is good.
Above-mentioned technical problem provide through the invention foundation wing of nose action signal determine respiratory effort method and according to
Respiratory effort for executing this method of the invention identifies equipment and sleep breath monitoring system device to solve.
The present invention determines the method for respiratory effort by the wing of nose movement sensing of detection wing of nose action signal according to wing of nose signal
Device and the processor of analysis wing of nose action signal are realized.Wing of nose movement includes wing of nose expansion and nasal ala retracted, steadily when breathing,
The wing of nose keeps slight contraction and expansion, the balance of maintenance air passage gas flow；When expiratory dyspnea, the wing of nose is in autonomic control
Lower increase expansion amplitude is to improve air-flow disengaging flow；Nasal blockage, when using mouth breathing, although nasal cavity apnea air-flow,
The movement of expansion and contraction when the wing of nose still maintains breathing.Wing of nose action sensor is exactly the sensing for detecting wing of nose motion amplitude
Device, the i.e. sensor of expansion and contraction degree.
Further, cooperate nasal airflow sensor, the above method also can be used to carry out the Classification and Identification of sleep apnea.
For example, if analysis wing of nose action signal determination has respiratory effort to recognize this apnea in apnea
Determine obstructive type；Analysis wing of nose action signal determines that then apnea is identified as maincenter type for the effort that breathes no more.
The present invention also provides a kind of equipment of respiratory effort for identification, and the equipment includes: wing of nose action sensor,
For acquiring wing of nose action signal；Processor is configured as: being coupled with wing of nose action sensor, is received wing of nose action sensor
Wing of nose action signal and analyze wing of nose action signal determine whether occur respiratory effort；Storage unit, with the processor electricity
Connection, the analysis result for storage processor.
In exemplary embodiment provided by the invention, wing of nose action sensor can select optical sensor or acceleration
Sensor, in addition, also can be selected piezoelectric transducer, myoelectric sensor, electric resistance sensor or other can reflect wing of nose action signal
Sensor.
In exemplary embodiment provided by the invention, the equipment of the respiratory effort for identification further includes a substrate,
In on subject's nose, the wing of nose action sensor is fixed in the substrate substrate Pasting, it is ensured that substrate paste with
When subject's nose, the wing of nose action sensor is located just at wing of nose position, can accurately acquire wing of nose action signal.
The present invention also provides a kind of devices for sleep apnea monitoring, and described device includes for acquiring the wing of nose
The wing of nose action sensor of action signal, it is described for acquiring the mouth and nose gas flow transducer and processor of respiratory air flow signal
Processor is configured as: coupled respectively with wing of nose action sensor and nasal airflow sensor, for receive wing of nose action signal and
Respiratory air flow signal；Analysis wing of nose action signal determines whether that respiratory effort occurs, analyzes respiratory air flow signal and determine whether to send out
Raw apnea determines that apnea type is maincenter type or obstructive type；The storage unit being electrically connected with the processor is used
In the analysis result for receiving and storing processor.
Further, thermistor or pressure sensor can be selected in the mouth and nose gas flow transducer；It should be noted, mouth and nose gas
The respiratory air flow signal of flow sensor acquisition includes nasal airflow signal and mouth breathing airflow signal.
Further, the sleep apnea monitoring device may also include blood oxygen transducer, and body moves sensor, alarm
Unit, display unit.
The present invention provides a kind of method and apparatus that completely new identification of breathing is made great efforts, the acquisition of wing of nose action signal is compared
It is more comfortable in the acquisition of Esophageal Pressure signal；It is more convenient compared to the acquisition of thoracic impedance signal.
The sleep apnea monitoring device provided through the invention, respiratory effort and nasal airflow are detected in nose, real
Existing signal acquisition is concentrated, easy to use, the good effect of comfort.
