Specific embodiment
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Under every other embodiment obtained, shall fall within the protection scope of the present invention.
The description and claims of this application and term " first ", " second ", " third " " in above-mentioned attached drawing Four " etc. be for distinguishing different objects, rather than for describing specific sequence.Furthermore term " includes " and " having " and Their any deformations, it is intended that cover and non-exclusive include.Such as contain a series of steps or units process, method, System, product or equipment are not limited to listed step or unit, but may include the step of not listing or unit.
In the prior art, replacing for ventilator can not often be consistent with the respiratory movement of user in time, cause to make User, which breathes, experiences bad, the even breathing of influence user when serious.Shown in Figure 3, two width waveform diagram of the top Fig. 3 is Pressure waveform figure, following two width waveform diagram are the waveform diagram of user's respiratory capacity, Neural T1It is anti-for user's nerve center The time for answering air-breathing to complete.Right-hand component is normally to replace in figure, and left-hand component is to replace slow situation, is replaced a little in right figure It is the 25% of peak flow, and is replaced a little in left figure if still maintaining 25%, will lead to and replaced slow, patient exhales tired Difficulty, present inventor have found after study, in left figure, if being a little adjusted to the 60% of air-breathing peak flow for replacing, this When patient expiration restore normal, flow curve is almost the same with right figure.
In consideration of it, the application determines the expiration of user and the separation of air-breathing by the real-time monitoring to user's ventilatory capacity, The relationship of the time replaced according to the separation corresponding time with ventilator is a little adjusted replacing for ventilator.Work as separation The corresponding time is greater than when replacing time, illustrate to replace too fastly, then will replace time corresponding flow and air-breathing peak flow-rate ratio Value is lowered, conversely, then carrying out a certain proportion of up-regulation.
It should be noted that above-mentioned application scenarios are merely for convenience of understanding the thought of the application and principle and showing, this The embodiment of application is unrestricted in this regard.On the contrary, presently filed embodiment can be applied to it is applicable any Scene.
After describing the technical solution of the embodiment of the present invention, the various non-limiting realities of detailed description below the application Apply mode.
Referring first to Fig. 4, Fig. 4 is the process signal that a kind of ventilator adjustment provided in an embodiment of the present invention replaces point methods Figure, the embodiment of the present invention may include the following contents:
S401: active user's breathing separation corresponding first time is obtained, ventilator replaces a little corresponding second time And the ventilator replaces a corresponding air-breathing peak flow ratio.
Determining at the first time can be according to following methods:
The capability value that the active user breathes within a preset period of time is obtained, and capacity song is generated according to the capability value Line (please refers to shown in Fig. 5), using the time of the vertex correspondence of the capacity curve as the first time.
When air-breathing, capacity rises, and when exhaling, patient's capacity can be gradually reduced, before being finally restored to air-breathing Volume size, the vertex P of capacity curve are exactly the separation of air-breathing and expiration.
The a little corresponding time that replaces of ventilator is when the certain percentage for detecting present flow rate as air-breathing peak flow When, determine that current is the separation of user's breathing, IPAP pressure will be replaced at this time as EPAP, or EPAP pressure will be removed It is changed to IPAP, the time replaced alternatively referred to as replaces a little.
Ventilator replaces a corresponding air-breathing peak flow ratio, that is, refers to when replacing, present flow rate and air-breathing peak flow Ratio, for example, when replacing a little be set as the 25% of air-breathing peak flow, refer to when current flow is air-breathing peak flow When 25%, the pressure of ventilator is replaced.25% is air-breathing peak flow ratio at this time.
S402: when the first time being greater than second time, the time that replaces of the ventilator being adjusted to, when Preceding flow value and the ratio of air-breathing peak flow are that air-breathing peak flow ratio lowers corresponding time when the first default percentage value.
S403: when the first time being less than second time, the time that replaces of the ventilator being adjusted to, when Preceding flow value and the ratio of air-breathing peak flow are that air-breathing peak flow ratio raises corresponding time when the second default percentage value.
First default percentage value can be identical with the second default percentage value, can also be different, and the first default percentage value, second are in advance It can also be other values, this does not influence the realization of the application certainly if percentage value can be 1%.
For example, current ventilator, which replaces, is a little set as the 25% of air-breathing peak flow, is greater than second when first time When the time, show to replace too fastly, can a little be set as the 24% of air-breathing peak flow for replacing, i.e., ought detect that present flow rate is peak stream Amount 24% when, replace;When first time is less than the second time, shows to replace too slowly, can will replace and a little be set as inhaling The 26% of gas peak flow replaces that is, when detecting present flow rate is the 26% of peak flow.Successively come guarantee at the first time It is as identical as possible as the second time, that is, guarantee that man-machine trace performance is good.
In technical scheme, by the respiratory movement of user and the ventilatory capacity of ventilator, in real time to ventilator The timeliness replaced a little is judged, to adjust replacing a little for ventilator in time.Ensure the respiratory movement and ventilator of user Replace and be consistent, to meet the respiratory demand of user, improve the usage experience of user, be conducive to improve respiratory disorder patient Comfort level, be conducive to improve respiratory disorder therapeutic quality.
When the time difference of first time and second time are enough small, it is believed that it is man-machine at this time to be consistent, It can not have to replace exchange a little, such as difference is 0.005s.Therefore based on the above embodiment, present invention also provides in addition One embodiment.It please refers to shown in Fig. 6, specifically can include:
S601: specifically describing with S401 consistent, and details are not described herein again.
S602: judge whether the first time and the time difference of second time are not more than preset threshold.
Preset threshold is 200ms, can also be other any values certainly, the application does not do any restriction to this.
S603: when judging that the time difference of the first time and second time are greater than preset threshold, when described the When one time was greater than second time, the time that replaces of the ventilator is adjusted to, present flow rate value and air-breathing peak flow Ratio be corresponding time when air-breathing peak flow ratio lowers the first default percentage value;It is less than institute when the first time When stating for the second time, the time that replaces of the ventilator is adjusted to, the ratio of present flow rate value and air-breathing peak flow is described Air-breathing peak flow ratio raises corresponding time when the second default percentage value.
It is specific to illustrate the introduction for please referring to above-described embodiment.
S604: it when the time difference for determining the first time and second time is not more than preset threshold, obtains The pressure curve of the breathing gas of the user.
When time difference ▽ t is less than 200ms, it is still desirable to the variation of flow waveform and pressure waveform is judged, with It obtains replacing the accurate conclusion whether synchronized.
S605: judge after the adjustment replace a little corresponding time before, the pressure curve whether there is peak value.
It is to analyze pressure waveform first, if pressure curve has obvious protrusion before replacing a little, please refers to Fig. 7 Shown in D point, then explanation replaces and still has sluggishness, and patient leads to have slight man-machine confrontation in forced expiration.
S606: it when determining that the time that replaces of the ventilator there are when peak value, is then adjusted to by the pressure curve, adjusts The a little corresponding air-breathing peak flow ratio up-regulation third that replaces afterwards presets corresponding time when percentage value.
When determine to replace there are still it is asynchronous when, then need to continue to raise third default hundred on a benchmark replacing originally Score value.It can be 1% that third, which presets percentage value, can also be other any values, this does not influence the realization of the application.
For example, working as at the first time constantly less than the second time, be a little set as the 26% of air-breathing peak flow for replacing, And when determine pressure curve there are when peak value, need to continuing to be adjusted on the basis of 26%, such as up-regulation 1%, i.e., when current Flow be air-breathing peak flow 27% when, ventilator replaces.
S607: when determining that peak value is not present in the pressure curve, the volume curve of the breathing gas of the user is obtained.
S608: judge the volume curve with the presence or absence of second peak value.
It is too fast in order to avoid replacing generation, it is also necessary to capacity curve be detected and judged.It please refers to shown in Fig. 8, if Occur second wave crest Q after P point, which shows that patient is still carrying out aspiratory action, be then likely to occur replacing Too early situation.
S609: when determining that the volume curve exists when second peak value, then the time that replaces of the ventilator is adjusted For a little corresponding air-breathing peak flow ratio adjusted that replaces lowers corresponding time when four default percentage values.
Third presets percentage value can be identical with the 4th default percentage value, can also be different, and all can be 1%, certainly, can also be Other values, this does not influence the realization of the application.
For example, working as at the first time constantly less than the second time, be a little set as the 26% of air-breathing peak flow for replacing, And when determine volume curve exist when second peak value, need to continue to be adjusted on the basis of 26%, such as downward 1%, i.e., When current flow is the 25% of air-breathing peak flow, ventilator is replaced.
From the foregoing, it will be observed that the embodiment of the present invention further judges the two time difference, ventilator is more accurately judged The timeliness that replaces a little, replaced a little to adjust ventilator in time.Ensure the respiratory movement of user and replacing for ventilator It is consistent, to meet the respiratory demand of user, improves the usage experience of user, be conducive to improve the comfortable of respiratory disorder patient Degree is conducive to the therapeutic quality for improving respiratory disorder.
