Embodying the exemplary embodiment of feature of present invention and advantage will describe in detail in the following description.It should be understood that the present invention can have various changes in different embodiments, it is neither departed from the scope of the present invention, and explanation therein and diagram are treated as purposes of discussion in itself, and is not used to the limitation present invention.
As previously described, although be all the inspection for carrying out congenital heart disease, still, congenital heart disease examination and the congenital heart disease inspection existed as a specific inspection project have significant difference between both.On the one hand, the congenital heart disease inspection existed as a specific inspection project will be combined realization using various methods, and to ensure accuracy, there will be and realize complicated and costly defect.
On the other hand, for congenital heart disease examination, because it is using all neonates as object, targeted scope is very wide, i.e., for all neonates, therefore, need reduction to realize complexity and expense, and possess relatively low loss, thus can be applied to all neonatal examinations.
How to reduce and realize complexity and expense, and it will be current important technological problems urgently to be resolved hurrily to possess relatively low loss, to cause the examination of congenital heart disease accomplished.
Therefore, spy proposes a kind of processing method of blood oxygen saturation.In one embodiment, specifically, as shown in figure 1, this method includes：
Step 110, carry out before conduit and blood oxygen collects before conduit oximetry data after oximetry data and conduit after conduit.
The collection of blood oxygen refers to the collection at the position in body residing for right oar or Temporal Artery etc., such as blood oxygen that the right hand palm is carried out before conduit；The collection of blood oxygen refers to the collection at the position residing for left oar, navel or artery of lower extremity etc., such as blood oxygen that sole is carried out after conduit.
Oximetry data after oximetry data and conduit is obtained with Postductal blood oxygen before conduit specifically, before passing through the conduit that preset two blood oxygen transducers are carried out and Postductal connection, before synchronous acquisition conduit.
It should be strongly noted that oximetry data is synchronous in time after oximetry data and conduit before resulting conduit.
Two blood oxygen transducers are prefixed, the two blood oxygen transducers are to realize that blood oxygen is gathered using photoelectric technology.Connecting the two blood oxygen transducers, and the two blood oxygen transducers are when being connected to corresponding position in body, you can carry out before conduit and after conduit blood oxygen collection.
Step 130, oximetry data obtains before conduit oximetry value after oximetry value and conduit after oximetry data and conduit before processing conduit.
The patient monitor being connected with blood oxygen transducer is respectively calculated to both oximetry datas and obtains before corresponding oximetry value, i.e. conduit oximetry value after oximetry value and conduit after oximetry data before obtaining conduit and conduit after oximetry data.
In the implementing of patient monitor, two blood oxygen modules will be equipped with, acquisition and processing with Postductal oximetry data before conduit are realized respectively, and by the data after processing, handle certain form that oximetry value after oximetry value before obtained conduit and conduit is converted to agreement, data after storage conversion, for subsequently transferring.
Step 150, oximetry value after oximetry value and conduit is obtained before the conduit of time synchronized.
In the simultaneous display carried out according to oximetry value after oximetry value before time upper synchronous conduit and conduit, blood oxygen saturation is concentrated in together before conduit and after conduit.In other words, check that interface can be directly obtained before the conduit corresponding to same time and Postductal oximetry value by a blood oxygen.
By concentrating the simultaneous display before the conduit carried out with blood oxygen saturation after conduit, so that the intuitive display before conduit with blood oxygen saturation after conduit is effective, user can check to obtain blood oxygen saturation before conduit and after conduit simultaneously, so thus can also directly obtain before current catheter and after conduit blood oxygen saturation situation.
It may be appreciated, oximetry value refers to before the conduit corresponding to same time point oximetry value after oximetry value and conduit after oximetry value and conduit before the conduit of time synchronized, or corresponding to oximetry value after oximetry value before the conduit of same time period and conduit.
It is by while before the conduit collected after oximetry data and conduit obtained by oximetry data between oximetry value after oximetry value and conduit before either which kind of form, acquired conduit.
Step 170, the oximetry value after oximetry value before a blood oxygen checks in interface the conduit for showing time synchronized and conduit.
Having laid a blood oxygen checks interface in advance, and the specific pattern corresponding to it can be laid out according to actual needs.
Checked in a blood oxygen in interface, display is corresponding to oximetry value after oximetry value before the conduit of same time point and conduit, even display is corresponding to oximetry value after oximetry value before the conduit of same time period and conduit, thus, it is possible to directly display the numerical values recited after conduit before oximetry value and conduit corresponding to oximetry value, in order to directly check that interface can obtain two kinds of synchronous at a time point and/or over a time period blood oxygen saturations by this blood oxygen, and then directly thus display can complete the examination of congenital heart disease.
In addition, during as described above, collection, processing and display before the conduit carried out with blood oxygen after conduit are lasting progress, accordingly, by oximetry value, the routine care related thus, it is possible to realize congenital heart disease after a blood oxygen checks in interface before the conduit of continuously display time synchronized oximetry value and conduit.
Before the conduit synchronous in time that said process is obtained after oximetry data and conduit oximetry data for congenital heart disease, it is the most physiological parameter of conspicuousness relatively, in this application, by introducing time upper both synchronous data, and by the simultaneous display of blood oxygen saturation before the conduit that is finally carried out and after conduit, the realization for congenital heart disease examination provides possibility.
In one embodiment, step 170 as shown in Fig. 2 including：
Step 171, waveform plot is carried out according to oximetry value after oximetry value before the conduit of time synchronized and conduit, obtains corresponding twice blood oxygen and trace waveform.
As shown in Figure 3, tracing the corresponding blood oxygen of oximetry value before obtained waveform, i.e. conduit and tracing blood oxygen saturation value after waveform and conduit is over time and carries out dynamic change.
Step 173, blood oxygen is traced into waveform it is shown in a blood oxygen and check interface, and the entitling that blood oxygen traces waveform is carried out according to corresponding blood oxygen saturation.
Check that tracing waveform to the twice blood oxygen of acquisition in interface shows in a blood oxygen, and every one of the blood oxygen shown traces waveform and marked oximetry value corresponding to it.
Waveform is traced for the blood oxygen that waveform plot acquisition is carried out according to oximetry value before conduit, this one of blood oxygen is traced into wave label for blood oxygen saturation is corresponding before conduit and traces waveform, waveform is traced for the blood oxygen that waveform plot acquisition is carried out according to oximetry value after conduit, then waveform is traced labeled as blood oxygen saturation is corresponding after conduit to it.
Check that the entitling carried out in interface traces waveform to distinguish different blood oxygens by blood oxygen, and then convenient use person tells the blood oxygen of display and traces the corresponding relation of waveform and respective blood oxygen transducer, prevent user from, by result mistake corresponding with blood oxygen transducer, triggering error in judgement.
Further, in the present embodiment, step 170 also includes：
The Dynamic Announce of oximetry value after oximetry value before the conduit for carrying out time synchronized in real time and conduit is checked in interface in blood oxygen, and corresponding perfusion degree is indicated for oximetry value after oximetry value before the conduit of Dynamic Announce and conduit.
Signified blood oxygen checks that the Dynamic Announce carried out in real time in interface refers to the oximetry value after oximetry value before blood oxygen checks the conduit for being shown in interface and being currently acquired and obtain and conduit.
And in this Dynamic Announce carried out, each oximetry value is labeled with corresponding perfusion degree, and then it is convenient for checking.
In one embodiment, step 170 as shown in figure 4, including：
Step 175, the configuration that a blood oxygen checks time shaft in interface is carried out according to oximetry value after oximetry value before the conduit of time synchronized and conduit.
The corresponding time is worth to from blood oxygen saturation after oximetry value before the conduit of time synchronized and conduit, the configuration that blood oxygen checks time shaft in interface is carried out according to the time of acquisition, the time shaft that the blood oxygen saturation in interface with that will show is adapted is checked to obtain blood oxygen.
Step 176, Drawing of Curve is carried out according to oximetry value after oximetry value before conduit and conduit respectively on a timeline, two blood oxygen trend curves of blood oxygen saturation Long-term change trend is characterized in time.
With collection and the lasting progress of processing, obtain and distinguish before corresponding conduit oximetry value after oximetry value and conduit with oximetry value after oximetry value before multiple conduits of time correlation and conduit, i.e., multiple time points.
On a timeline, according to the numerical values recited of oximetry value after oximetry value before conduit and conduit, Drawing of Curve is carried out according to the time point corresponding to it, to be characterized two blood oxygen trend curves of blood oxygen saturation Long-term change trend in time.
Further, will be using blood oxygen saturation as ordinate, the time shaft of configuration is abscissa, curve is drawn in the region of ordinate and abscissa formation according to oximetry value after oximetry value before conduit and conduit respectively, the corresponding blood oxygen trend curve of oximetry value after the corresponding blood oxygen trend curve of oximetry value before conduit and conduit is obtained.
Step 177, entitling is carried out to blood oxygen trend curve according to corresponding oximetry value.
The blood oxygen trend curve of acquisition corresponds respectively to different oximetry values and different blood oxygen transducers, therefore, by the entitling for carrying out blood oxygen trend curve, it is able to directly check that the oximetry value and corresponding blood oxygen transducer that any blood oxygen trend curve characterized are known in interface by blood oxygen.
Further, in one embodiment, method as described above also includes：
Using a blood oxygen trend curve as aim curve in two blood oxygen trend curves, the reference curve being adapted with another blood oxygen trend curve is drawn according to preset reference value, the absolute difference between two blood oxygen trend curves and the magnitude relationship of reference value can be obtained by reference to curve.
As previously described, it is corresponding with blood oxygen transducer, one blood oxygen checks interface while all blood oxygen transducers for connection have carried out the display of data, therefore, as blood oxygen check interface can by blood oxygen transducer corresponding to two blood oxygen trend curves know that body currently carries out the situation of blood oxygen collection, and then the examination and routine care of the situation for congenital heart disease such as time oximetry value corresponding with the time according to corresponding to blood oxygen trend curve, absolute difference between the two provide data support.
Therefore, the reference curve drawn and be adapted with blood oxygen trend curve in interface is checked in blood oxygen, the reference curve is used to be that congenital heart disease examination and routine care obtain data from blood oxygen trend curve and support to provide effectively auxiliary.
According to actual needs, a preset reference value, for example, the reference value can be 3%.For carrying out two blood oxygen trend curves that Drawing of Curve is obtained, any one blood oxygen trend curve will be chosen and be used as aim curve, the drafting of reference curve is carried out according to aim curve and preset reference value, in the drafting of reference curve, allow for another blood oxygen trend curve including region between aim curve and reference curve, i.e., obtained by reference curve must be adapted with another blood oxygen trend curve.
Specifically, if the aim curve chosen is fallen within below another blood oxygen trend curve, reference line Trend value is then obtained by the corresponding oximetry value of aim curve and preset reference value sum, and then it is that can obtain reference curve to carry out Drawing of Curve according to reference line Trend value.
If the aim curve chosen is fallen within above another blood oxygen trend curve, reference line Trend value is then obtained by the difference between the corresponding oximetry value of aim curve and preset reference value, and then reference curve is obtained according to reference line Trend value progress Drawing of Curve.
In the presence of reference curve, checked in blood oxygen in interface by observing in blood oxygen trend curve to fall between reference curve and another blood oxygen trend curve with the presence or absence of a blood oxygen trend curve, the magnitude relationship between the absolute difference and reference value after oximetry value before conduit and conduit between oximetry value is judged with this, and then data foundation is provided for the diagnosis of congenital heart disease.
By reference to the drafting of line, for user, check that the observation carried out in interface can just obtain the data foundation for carrying out congenital heart disease diagnosis in blood oxygen, reading and comparison without voluntarily carrying out respective value, it also can in time know when data burst changes, enhance data sensitive and accuracy.
In one embodiment, method as described above also includes：The reference zone formed between sign aim curve and reference curve.
As previously described, whether a blood oxygen trend curve falls the data foundation that will be diagnosed between aim curve and reference curve as congenital heart disease.For blood oxygen checks interface, reference zone is formed between aim curve and reference curve.Under normal circumstances, reference zone will be fallen into by being different from another blood oxygen trend curve of aim curve, if the blood oxygen trend curve exceeds reference zone suddenly, then there is congenital heart disease, therefore reference zone will be indicated, to cause reference zone more prominent and directly perceived in the presence that blood oxygen is checked in interface.
The reference zone sign carried out can be that reference zone is realized using the mode of shade or certain color filling.Wherein, the height of reference zone is preset reference value, and more accurate and visual data foundation is provided for the diagnosis of congenital heart disease by this mode.
In one embodiment, method as described above also includes：
Vernier is set on a timeline, and vernier shows corresponding numerical value automatically with the intersection of arbitrary curve, the numerical value is the corresponding oximetry value of intersection.
The vernier set on time shaft is upwardly extended using time shaft by starting to be formed, it can be moved on a timeline, and the intersection in itself and arbitrary curve when stopping carries out the automatic display of respective value, thus need not will compare in each curve can just directly obtain with the numerical value corresponding to the intersection of vernier, the convenient random acquisition for carrying out all data on random time point, further increases the simplification that congenital heart disease examination and routine monitoring are realized.
In one embodiment, blood oxygen trend curve is drawn on using time shaft as abscissa, and blood oxygen saturation is in the region of ordinate, step 170 also includes：
According to the blood oxygen trend curve that carries out obtained by Drawing of Curve and/or it is preset effectively check that the time carries out coordinate regulation, blood oxygen trend curve is adapted to region and/or preset effectively check the time.
On the one hand, for the blood oxygen trend curve obtained by carrying out Drawing of Curve, each blood oxygen trend curve has all corresponded to certain blood oxygen saturation scope, therefore, blood oxygen saturation scope according to corresponding to blood oxygen trend curve carries out the regulation that blood oxygen checks ordinate in interface, the region constituted to cause blood oxygen trend curve can adapt in ordinate and abscissa.For example, in the region, blood oxygen trend curve is to be shown between two parties.
Specifically, minimal oxyhemoglobin saturation value is obtained according to blood oxygen saturation scope in blood oxygen trend curve, and then the numerical value for carrying out ordinate according to this minimal oxyhemoglobin saturation value is adjusted.
For example, being provided with three scale values on ordinate, if minimal oxyhemoglobin saturation value is less than or equal to 90%, three scale values on ordinate are automatically adjusted as 95,90 and 85 from top to bottom.If three scale values that minimal oxyhemoglobin saturation value is more than on 90%, ordinate automatically adjust as 100,95 and 90 from top to bottom.
On the other hand, for in the congenital heart disease examination and routine monitoring realized by blood oxygen trend curve, the observation carried out will be repeated, therefore, accordingly existing one effectively checks the time, this effectively the time of checking be the corresponding oximetry value of continuous observation in blood oxygen trend curve time interval, for example, its can be 1 hour.
Therefore, for the display of blood oxygen trend curve, can preset one effectively check the time, further according to preset effectively checking, the time carries out Coordinate Adjusting, so that the display of blood oxygen trend curve can adapt to effectively check the time in preset, and then conveniently check this blood oxygen saturation effectively checked within the time.
If the time is 1 hour for preset effectively checking, the blood oxygen saturation that the resulting blood oxygen trend curve of coordinate regulation will be shown in a hour is carried out.
Further, it is configured for convenience, it is preset effectively to check that the time be that the setting of time interval in passage time axle is realized.For example, for preset 1 hour effectively check the time, in time shaft can setting time at intervals of 20 seconds.
It should be noted that the coordinate regulation carried out includes abscissa regulation and/or ordinate regulation, the regulation of the regulation, even abscissa and ordinate of abscissa or ordinate can be carried out according to actual conditions.
The realization of coordinate regulation can be progress adaptively carry out or manual, can also be adaptive and be combined progress manually, and implementing will set according to actual clinical situation.
For example, can manually be adjusted come the time interval in the scale value or abscissa to ordinate by the triggering of specific keys.
Pass through carried out coordinate regulation so that blood oxygen checks that the display of blood oxygen trend curve in interface is more flexible, farthest meet the Clinical practice demand of user, facility provides the user clinical reference foundation exactly.
In one embodiment, step 170 as described above also includes：
The generation disturbed in detection blood oxygen collection, and carry out respective identification in the blood oxygen trend curve obtained by carrying out Drawing of Curve.
In the blood oxygen collection for being connected to the privileged site of body by blood oxygen transducer and realizing, it there is external factor often and cause the blood oxygen in certain time to gather and there is interference.For example, blood oxygen transducer comes off, blood oxygen signal is interfered, when this external factor occurs, alarm, and the partial trace in blood oxygen trend curve corresponding to mark time period will be produced.For example, this partial trace is designated into red curve.
Pass through the mark of partial trace in blood oxygen trend curve, so that user by blood oxygen when checking that interface is observed, user can be pointed out to exclude this partial trace, and observed using remaining curve not identified, to obtain the clinical foundation of more effective and accurate congenital heart disease examination and routine monitoring.
Process as described above and in the congenital heart disease examination realized, can reliably be detected in a short time, and the detection can continue to carry out, therefore, rate of missed diagnosis is very low.
In blood oxygen saturation processing provided herein, for its application in congenital heart disease examination, due to avoiding the need for being operated after connecting corresponding body part in blood oxygen transducer, medical personnel's workload is small, and operating efficiency is high, while will not also cause being significantly increased for medical expense, therefore, can popularize the preliminary screening of congenital heart disease on a large scale, so can as Congenital Heart Disease of Newborns measuring apparatus, and be quickly promoted.
