Such asfigure 1 As shown, the embodiment of the present invention provides a chest internal pressure measuring device, including: processor 1, synchronous database 2, and port internal pressure measuring device 3.
[0044]In the embodiment of the present invention, the mouth internal pressure measuring device 3 can be, for example, a port internal pressure measuring apparatus used in Patent Document 1, or an inner pressure measuring apparatus in other prior art for acquiring the mouth of the measured person.
[0045]The synchronous database 2 stores a synchronous chest pressure measurement data B = (B)1, B2, ..., bm) And synchronous port internal pressure measurement data m = (m1, m2, ... Mm), The synchronous chest pressure measurement data and the synchronous port internal pressure measurement data are obtained by performing mouth internal pressure measurement by performing the measured in the chest pressure, wherein BiAnd miThe synchronous chest pressure value and the mouth internal pressure pressure value obtained by the first preset time DT, respectively, and the value of I is 1 ... m. In a schematic embodiment, the preset time DT is set to be able to fully describe a time of breathing cycle waveform, such as the anneth average, complete a breathing, and the preset time DT can be set to, for example, 0.1-0.3 seconds. Such a breath will be sampled from 10-30 points.
[0046]The processor 1 performs a computer program for implementing the following steps:
[0047]S100 determines the mapping relationship of the thoracic pressure and mouth internal pressure of the measured person based on the synchronous chest pressure measurement data and the synchronous port internal pressure measurement data.
[0048]S200, according to the mapping relationship and the actuator's preset time period (e.g., 3 second) of the above-described mouth internal pressure measuring device, the corresponding real-time chest pressure is obtained and displayed.
[0049]S300, the curve of the synchronous port internal pressure measurement data and the resulting real-time chest pressurizing curve are shown and compared.
[0050]In an embodiment of the present invention, the processor 1 can be disposed in the cloud, and may also be disposed locally, for example, on the mobile terminal of the measured person.
[0051]Further, in the embodiment of the present invention, in S100, the mapping relationship of the chest internal pressure and the mouth is linear relationship, and specifically: b = α * m + β, α and β are the mapping relationship. The coefficients.
[0052]Further, in one embodiment, in S100, the data M can be measured according to the synchronous chest pressure measurement data B and the synchronous port, and α and β are determined using the least squares. How to specifically use the least squares method to determine α and β can be prior art, in order to avoid explanation, the present invention will be described with reference to the specific introduction. The determined coefficient α and β can be stored in a non-volatile register. The register can be a component of the chest internal pressure measuring device.
[0053]Further, in another embodiment, in S100, the synchronous thoracic voltage measurement data B and the synchronous port internal pressure measurement data M can be quickly denoised, and then α and β are determined using the least squares. By eliminating the noise of the equipment itself due to the apparatus of the chest pressure measurement device and the mouth, in particular the burr noise of the device, the accuracy of the coefficient α and β can be improved. Specifically, S100 may further include the following steps:
[0054]S110, the synchronous thoracic voltage measurement data B and the synchronous port internal pressure measurement data M perform denoising treatment, resulting in a synchronous chest pressure measurement data B 'and synchronous port internal pressure measurement data M'.
[0055]S120, based on the subinterruption measurement data B 'and the synchronous port internal pressure measurement data B' and the synchronous port after the deduction treatment, the α and the β are determined using the least squares.
[0056]S130, the α and the β are stored.
[0057]In one illustrative embodiment, S110 further includes:
[0058]S111, get the difference data DB = (DB) DB = (DB) DB = (DB)1, DB2, ..., DBm-1) And synchronous port internal pressure measurement data m Data DM = (DM1DM2, ..., DMm-1), Where DBj= Bj+1-BjDMj= Mj+1-MjThe value of J is 1 ... (m-1).
[0059]S112, if DBJ-DMJ is greater than the preset threshold, then Bj+1And mj+1Examples of the noise point are removed, B 'and M' after the noise is removed. The preset threshold can be an empirical value, and the present invention is not particularly limited.
[0060]In another illustrative embodiment, S110 may further include:
[0061]S113, get the difference data DB = (DB) DB = (DB)1, DB2, ..., DBm-1) And synchronous port internal pressure measurement data m Data DM = (DM1DM2, ..., DMm-1), Where DBj= Bj+1-BjDMj= Mj+1-MjThe value of J is 1 ... (m-1).
[0062]S114, if Bi+1≥Bi, Then dbi = first identifier, otherwise, DBI = second identification;
[0063]If Mi+1≥MiSo DMI = first identification, otherwise, DMI = second identification; the first identification and the second identification are different. In one illustrative embodiment, the first identity can be set to 1, and the second identification can be set to 0.
[0064]S115, if DBiNot equal to DMi, Then put Bi+1And mi+1Examples of the noise point are removed, B 'and M' after the noise is removed.
[0065]The steps S113 to S115 can more quickly remove the noise points in the synchronous chest pressure measurement data B and the sync port internal pressure measurement data M, and can be improved for the processor set in the cloud. Handling speed, saving resources.
[0066]The use of the least squares method in step S120 determines α and β can be prior art. The α and β in step S130 can be stored in a non-volatile register.
[0067]Further, in another embodiment of the present invention, in S100, α and β can be obtained directly by the preset calculation formula without using the least squares method. In one example, α and β can be determined based on the synchronous chest pressure measurement data B and the synchronous port internal pressure measurement data m. specifically:
[0068]α is based on determine;
[0069]beta is based on determine;
[0070]Among them, DBj= Bj+1-BjDMj= Mj+1-Mj.
[0071]In another example, α and β can be determined based on the denozable synchronous thoracic voltage measurement data B 'and the synchronous port internal pressure measurement data M', and can be denoched synchronous chest by the same method as the foregoing embodiment. Internal pressure measurement data B 'and synchronous port internal pressure measurement data m'. specifically:
[0072]α is based on determine;
[0073]beta is based on determine;
[0074]Where DB 'k= B 'k+1-B 'kDM 'k= M 'k+1-M 'k, N is the number of internal pressure measurement data of the synchronous inlets after denoising.
[0075]In this embodiment, α and β can be determined by using a preset calculation formula, and the amount of calculation is greatly reduced, and resources can be saved.
[0076]Further, in the embodiment of the present invention, S200 may further include the following steps:
[0077]S210, real-time acquisition of the mouth internal pressure measurement value M0 measured by the mouth internal pressure measuring device;
[0078]S220, according to the α and the β, obtain the corresponding real-time chest pressure measurement value B0 = α * m0 + β;
[0079]S230, the real-time chest pressure measurement value B0 is displayed.
[0080]In one embodiment of the invention, for example, the real-time chest pressure measurement value B0 can be presented on a display oscilloscope of the chest internal pressure measuring device to be capable of exhibiting a resulting chest pressure on the oscilloscope.
[0081]In another embodiment of the invention, the real-time chest pressure measurement value B0 can be presented on the mobile terminal of the measured person to be used by the measured person. Therefore, the chest internal pressure measuring apparatus according to the embodiment of the present invention may further include a communication module for transmitting real-time chest pressure measurement value B0 to the user's mobile terminal, thereby displaying waveforms, further, mobile terminals on mobile terminals. (PAD, mobile phones, etc.) can also record in real time-measured port internal pressure measurement values M0.
[0082]Further, in the embodiment of the present invention, S300 can further include the following steps:
[0083]S301, a M0 curve that displays the M curves of the synchronous port and real-time intake of the inner pressure measurement value M0 variant over time on the mobile terminal of the measured M0.
[0084]Generally, M is measured in hospitals, which can be considered accurate, especially in synchronization of the measurement of chest pressure measurement data B. However, M0 is measured at home, which is measured in a healthy state, but it may be interfered with many situations, such as measurement, and no standards result in measurement errors. If there is a cough, there is a cough, and it will bring it. The noise measured by M0, causing the B0 because of the range of inaccurate falling into the warning value. Therefore, a curve that can be changed over time can be presented on the display screen of the mobile terminal of the surveyor to compare two curves.
[0085]S302, receive one or more time pairs of the M curve and M0 curve specified by the user (Sk, Ek), K = 1, or, k>1, SkIndicates that the start time, EkIndicates the end time.
[0086]This step can be further included:
[0087]S3020, receiving the start time S specified on the M0 curvekThen, then the start time SkThe corresponding point is dragged to the corresponding point on the M curve.
[0088]Such asfigure 2 As shown, the user specifies two time pairs: (S1, E1) and (S2, E2). Obviously, the location user of E1 can be designated as E11, or may be specified as E12. The mobile terminal can prompt the user in writing or speech (SkEkThe intervals include peaks and valley values. This step may specifically include:
[0089]S3021, receiving the end time e specified on the M0 curvek, Then based on the start time SkWith the end time ekTime span, automatically marked the corresponding reception time E on the M curvek, Where, in the M curve, end time ekThe coordinates on the timeline are start time skTime axis coordinates and time span and value, that is, end time ekThe coordinates on the timeline are start time skTime axis coordinate + time span.
[0090]S303, based on the time to display a corresponding M0 curve on the mobile terminal of the measured person.
[0091]Specifically, time pair (Sk, EkThe M0 curve and M curves are flat to M-M0 curve. Thus, the user can visually see the contrast state after M and M0 removes noise.
[0092]Further, when the M0 curve is drawn, the portion from the M curves uses the first color, and the part from the M0 curve uses the second color, and the end time ekAnd start time sk+1The part of the partial white drafting, that is, the curve between two time pairs is not drawn to remove noise in the curve. The first color is different from the second color.
[0093]Further, when the M0 curve is drawn, if the curve from the M curve is partially coincided with a curve from the M0 curve, then the coincidence portion uses the third color to coarry, wherein the third color value is 0.5 * first color. Value + 0.5 * second color value. The third color is different from the first color and the second color.
[0094]Further, when drawing the M0 curve, if the end time ekAnd start time sk+1The time interval exceeds the preset threshold, for example, 1 second, then set the time interval to the preset threshold, and presentation time compression marks on the M0 curve, for example "~".
[0095]Thus, by the M-M0 curve presented by the above content, it is possible to display the difference between the synchronous port internal pressure measurement data and the real-time intake port, so that the measured person can clearly know that their chest pressure is known.
[0096]Further, in the embodiment of the present invention, the user dragged on the display of the mobile terminal.kWhen it is easy to make mistakes, in order to improve the user experience, the processor 1 is also used in:
[0097]On the display screen of the mobile terminal, the peak and valley values of the M curves and M0 curves are automatically prompted.image 3Indicated (shown)image 3What is shown is a M curve, and the M0 curve is also according to it.image 3The way the curve is automatically enlarged.
[0098]Specifically, when the user clicks on the peak of the M0 curve and dragging the peak to the M curve, all peaks on the M curve flash corresponding to the user alignment. This type of automatic valley and peak of automatic magnifying curve is much faster than existing "Zoom -> Select".
[0099]In summary, the visual cavity internal pressure measuring apparatus provided by the embodiment of the present invention, since the mouth internal pressure measurement data is measured by the mouth-bysection of the mouth internal pressure measurement data and the synchronous end pressure measurement data to determine between the chest internal pressure and the mouth internal pressure. Mapping relationship, therefore, the mapping relationship is accurate. When you need to measure the chest pressure, depending on the determined mapping relationship, the user can directly calcire the corresponding chest pressure, such as the internal pressure, to reduce the time of the user to go to the hospital, and to avoid invasive measurements Not suitable, simple and convenient, user experience. And the curve of the obtained real-time chest pressure and the synchronous port internal pressure measurement data can be displayed on the user's mobile terminal to allow the user to intuitively know the difference between the two and visual effects.
