Description

Medical device Technical Field

The application relates to the technical field of medical equipment, and particularly provides medical equipment.

Background

At present, the incidence rate of Congenital Heart Disease (CHD) is high, and the Congenital Heart Disease (CHD) is not easy to be looked at. Relevant survey data indicate that: in some countries, the incidence of Congenital Heart Disease accounts for about 8-12% of the number of live born neonates, and about 1.2-1.7% of the number of live born neonates have severe life-threatening Congenital Heart Disease (CCHD); in China, the actual incidence rate of congenital heart disease of live newborn is 26.6 per thousand, and the incidence rate of severe congenital heart disease is 3.5 per thousand. Congenital heart disease, whether direct or indirect, is a common cause of death due to cardiac malformation and is also the leading cause of death in the neonatal period.

Diagnosing congenital heart disease requires the use of cardiac ultrasound, which requires the presence of ultrasound equipment and a corresponding sonographer, which is clinically demanding. If all neonates are subjected to cardiac ultrasonic diagnosis, the diagnosis cost is high and the efficiency is low. Cardiac ultrasound is also not necessary for normal neonates.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The medical equipment that this application provided mainly is based on percutaneous blood oxygen saturation value, and the blood oxygen saturation value through detecting two health positions of detection confirms output result information, and the testing process is not invasive and with low costs. It should be noted that the medical device provided by the present application may be used for screening congenital heart disease of a newborn, and may also be used in other scenarios requiring blood oxygen measurement.

In a specific embodiment, the medical device includes a blood oxygen saturation detection channel (referred to as a detection channel for short), and the detection channel includes a measurement module such as a blood oxygen probe, and the blood oxygen probe can acquire a transcutaneous blood oxygen saturation value (transcutaneous blood oxygen saturation value may be referred to as a blood oxygen value for short) of a detected object. One implementation of the measurement module is a light sensor that generates an oximetry signal, such as a transcutaneous blood oxygen saturation signal, based on light attenuation information of the emitted light at least two wavelengths after penetrating the body part. In the embodiment of the present application, at least the first result information is determined to be output based on the determination rule and the measured blood oxygen saturation value.

In a specific embodiment, the determination rule requires the use of blood oxygen values at two sites of the test object. Therefore, the medical staff needs to operate the measurement module many times, and the measurement starting time point, the measurement time, the measurement steps and other contents in the operation process need to be controlled by the personal ability and experience. Therefore, the detection process is not automatic and convenient enough, and the accuracy of the detection result can be influenced by artificial uncertain factors.

Therefore, the application also provides medical equipment which can guide the detection operation process of an operator, and further improves the convenience and accuracy of detection.

As shown in fig. 1, a testing procedure performed by a medical device is shown. The detection procedure may be performed with the newborn as a detection target, for example, within a period of 24 hours to 48 hours after the birth of the newborn, or within a short period of time after the birth but before the discharge from a hospital, which is less than 24 hours after the birth. Of course, in practical applications, other objects having detection requirements may also be used, or the detection time point may also be other time points, and is not limited to this.

Specifically, the detection process comprises the following steps 1.1-1.4:

step 1.1: blood oxygen signals of two parts of a detected object are obtained.

Specifically, a first blood oxygen measurement signal measured by at least one optical sensor from a first body part of a detection object and a second blood oxygen measurement signal measured from a second body part of the detection object are obtained; the optical sensor generates an oximetry signal based on light attenuation information of the emitted light with at least two wavelengths after the light penetrates through the body part of the detection object

Wherein, the blood oxygen collecting device is used for measuring the detection object, and the measurement content comprises the blood oxygen saturation of the upper limb and the lower limb. The upper limb may specifically be a hand (e.g. right hand) of the detection subject, and the lower limb may specifically be a foot of the detection subject.

Step 1.2: and acquiring blood oxygen saturation values of two body parts of the detected object. Specifically, a first blood oxygen saturation value and a second blood oxygen saturation value are obtained respectively based on the first blood oxygen measurement signal and the second blood oxygen measurement signal.

Step 1.3: based on the first blood oxygen saturation value and the second blood oxygen saturation value, whether one of the following three conditions is satisfied is judged:

the first blood oxygen saturation value or the second blood oxygen saturation value is smaller than a first threshold value;

the obtained first blood oxygen saturation value and the second blood oxygen saturation value are located between a first threshold value and a second threshold value;

the absolute value of the difference value of the obtained first blood oxygen saturation value and the obtained second blood oxygen saturation value is larger than a third threshold value;

wherein the first threshold is less than the second threshold

Step 1.4: in step 1.3, it is determined that one of the three conditions is satisfied, first result information is output.

In one embodiment, if the blood oxygen saturation level of either the upper limb or the lower limb in the measurement data is less than 90%, the first result information may be directly determined to be output.

If the measured result is that the blood oxygen saturation of either the upper limb or the lower limb is 95% or more and the difference between the blood oxygen saturation of the upper limb and the blood oxygen saturation of the lower limb is 3% or less, the second result information can be directly determined to be output. The second result information is a detection result opposite to the first result information.

If the blood oxygen saturation of the upper limb and the lower limb in the measured data is within 90-95%, and the difference value of the blood oxygen saturation of the upper limb and the blood oxygen saturation of the lower limb is more than 3%, the first result information can be directly output. Of course, further, when such a condition is satisfied, the measurement result may be determined to be suspect, and the input of the first result information or the second result information may be determined depending on the measurement result obtained twice/three times. That is, when the measurement result has a suspected result, the subsequent measurement operation is required, and the procedure returns to step 1.1 to perform the blood oxygen measurement on the test object again. The different measurement operations may be separated by a certain period of time, for example by 1 hour.

In the case of a suspected situation, the number of times of repeating the measurement may be controlled. Specifically, the number of times of measurement may be recorded, and in the case where the result obtained from the measurement data is suspected, it is determined whether the number of times of measurement reaches 3 times, and if so, the step 1.1 is not returned, but the first result information is directly determined to be output.

The first result information and the second result information output by the medical device can be referred by medical staff so as to judge the detection object in some aspects.

The following points are required for the above-described determination rule.

First, the respective threshold values in the judgment conditions are not limited to the values provided in the above-described embodiments, but may be other values approved by the medical judgment rules, or values set by the medical staff according to clinical experience. For convenience of description, the threshold value represented by 90% may be referred to as a first threshold value, the threshold value represented by 95% may be referred to as a second threshold value, and the threshold value represented by 3% may be referred to as a third threshold value.

In addition, the interval duration between different measurement operations is not limited to 1 hour, and may be set to other values according to actual detection requirements. The number of measurements is not limited to three, and may be set to other values according to actual detection requirements.

The resulting information may be derived from one measurement operation or from multiple measurement operations. If multiple measurements are required, the operator needs to control the interval duration between each measurement. In one measurement operation, the blood oxygen saturation of different parts of the upper limb and the lower limb also needs to be acquired. The operation process is complicated and needs to be controlled manually by depending on experience.

In this regard, a medical device (e.g., a multi-parameter monitoring device, a blood oxygen monitoring device, etc.) provided by the present application can guide an operation process through prompting and can prompt a measurement result. The medical devices mentioned in the present application are not limited to the monitor, but include invasive/non-invasive ventilators with monitoring function, nurse stations, central stations, and the like.

In practical applications, the blood oxygen saturation detection channel of the medical device may include one or more than one. The number of detection channels is different, and the detection procedures executed are different. If only one detection channel is included, the same detection channel is needed to be used for measuring the blood oxygen saturation of different parts respectively; if multiple detection channels are involved, the oxygen saturation levels of blood at different sites can be acquired simultaneously using the multiple detection channels.

The following describes the detection process based on single detection channel and the detection process based on dual detection channel.

Referring to fig. 2, a single detection channel based detection procedure, which may also be referred to as a single blood oxygen detection procedure, is shown. As shown in FIG. 2, the process may specifically include steps S201-215.

S201: and outputting first prompt information, wherein the first prompt information comprises operation content and/or notice before the blood oxygen value measurement is carried out on the first part.

Here, the presentation information may be referred to as first presentation information for the sake of distinguishing from other presentation information. The medical device may output the prompt in a variety of ways including, but not limited to, voice, interface text, and the like.

The first prompt message is used for prompting the medical staff about the operation items before the blood oxygen measurement, including but not limited to operation contents and/or attention items. For example, the medical staff is prompted to connect the measurement module with the upper limb of the detection object; for another example, the medical staff is prompted to measure the object only after the state of the detected object is calm; for another example, the medical staff is prompted to manually trigger the blood oxygen value measurement process, for example, the first prompt message includes a start button, and the measurement module starts to collect the blood oxygen value of the detection object only after the user triggers the start button.

The determination rule includes the sites where the blood oxygen level needs to be detected, and the number of the sites may be two or other. The present application takes two detection sites, hand and foot, as an example.

The flow is a detection flow with a single detection channel, the blood oxygen values of two parts are measured successively, for convenience of description, the part measured firstly can be called as a first part, and the part measured subsequently can be called as a second part. The first part may be a hand or a foot.

Assuming output in the form of interface text, an example of a detection interface is shown in fig. 3A. As shown in FIG. 3A, the detection interface includes a first area 301 in which the prompt text "please connect the oximetry probe to the right hand of the infant" is displayed. Also, the area may display the prompt text "start measurement after baby is quiet". The two prompt texts can be simultaneously displayed in one detection interface, and of course, the first text can be prompted first, and then the second text can be prompted.

In addition, the detection interface may further include a second area 302 (for displaying a blood oxygen trend graph of the right hand), a third area 303 (for displaying a blood oxygen trend graph of the foot), and a fourth area 304 (for displaying measurement results, such as the first result information, the second result information, or others). The fourth area 304 includes a "start measurement" button to prompt the medical staff to press the button to start measurement after the above-described operation is performed.

S202: the method comprises the steps of obtaining a real-time blood oxygen value of a first part collected in a preset time period, generating a blood oxygen trend graph based on the real-time blood oxygen value, and outputting the blood oxygen trend graph.

The medical equipment comprises a measuring module, and after the measuring module is connected with a first part of a detection object, the blood oxygen value of the part can be acquired. For accuracy of the data acquisition, the acquisition is not done once, but the real-time blood oxygen values at the first site are continuously acquired over a continuous period of time. The length of the period may be preset, and thus may be referred to as a preset period. For example, the length of the preset time period may be set to 40 seconds. Of course, the value may be set to other values according to actual conditions.

The measurement module sends the real-time blood oxygen value of the first part to a processor of the medical equipment, and the processor can generate a trend graph of the blood oxygen saturation according to the real-time blood oxygen value of the first part. The trend graph may be drawn in any conventional manner, and is not described herein in detail. The trend graph is refreshed as the collected real-time blood oxygen values are updated, e.g., a new blood oxygen measurement is obtained and the trend graph is refreshed.

The blood oxygen trend graph may show the length of a preset time period, for example, the abscissa of the blood oxygen trend graph is a time axis, and the ending time point of the time axis may be set to 0 to indicate the time point of the end of the test as the current time point; the starting time point of the time axis is set to a length value of the preset time period and is a negative number to indicate that the measurement is started from a time point which is a preset time period length away from the current time point.

The blood oxygen trend graph shows the change of the blood oxygen value in real time within a preset time period. If the blood oxygen value changes greatly, the accuracy of the target blood oxygen value is affected, and the accuracy of the detection result is further affected. According to the blood oxygen trend graph, the medical staff can know whether the blood oxygen value of the detected object is stable during the blood oxygen measurement period, namely within the preset time period. If the blood oxygen value is unstable, the blood oxygen value of the detected object can be stabilized by various medical means such as physics and the like, and the blood oxygen value can be measured again. Of course, in some implementations, the blood oxygenation trend map may not be output.

S203: and outputting second prompt information, wherein the second prompt information comprises related information and/or cautionary matters in the process of measuring the blood oxygen value of the first part.

As mentioned above, the blood oxygen level measurement at the first location is a process, and in this process, some prompt information may be output to the medical staff to prompt the medical staff about the operation items that need to be noticed during the measurement process, or prompt the medical staff about the related information generated during the measurement process, or both. The relevant information in the blood oxygen value measurement process may include, but is not limited to, timing corresponding to a preset time period.

The medical device may output the second prompting message through an output module such as an audio module and/or a display module. For example, the second prompt message may be output through a detection interface provided by the display module, further, if the second prompt message includes timing in the measurement process, the form of presentation of the timing in the detection interface may be a timing progress bar, a timing dial, or a timing number, and specifically, the form of countdown may be used for prompting.

In one implementation, see FIG. 3B for yet another example of a detection interface. As shown in fig. 3B, the detection interface includes a first area 311, a second area 312, a third area 313 and a fourth area 314.

The first area 311 shows the prompt text "during measurement, please keep the baby as quiet as possible! ", and a countdown progress bar is shown. Specifically, the duration of the progress bar may be 40s, the light color part of the progress bar is the elapsed time length, the dark color part is the remaining time length, and the prompt text "remaining 25 s" is displayed.

Assuming that the blood oxygen value of the right hand is currently measured by the detection channel, and the length of the predetermined time period is 40 seconds(s), the second region 312 displays the blood oxygen trend map of the right hand in the sub-region corresponding to the right hand. The blood oxygen trend graph time axis has a start time point of-40 s and an end time point of 0. Of course, the time points may not be displayed in the blood pressure trend graph. According to the countdown of the progress bar, the blood oxygen trend graph is obtained after the measurement duration is 15 seconds.

It should be noted that, the execution sequence of step S203 is executed after step S202, and it may indicate a case that the output starting time point of the blood oxygen trend graph is earlier than the output time point of the second prompt message. Of course, this step is not limited to be executed after step S202, and may be executed simultaneously when the blood oxygen trend graph is output in step S202.

For example, after obtaining the real-time blood oxygen value of the first portion, the real-time blood oxygen value is added to the blood oxygen trend graph, the detection interface displays the changed blood oxygen trend graph in real time, and may display the second prompt message, and the countdown in the second prompt message changes as the measurement process progresses.

S204: and obtaining a target blood oxygen value based on the real-time blood oxygen value of the first part, and outputting the target blood oxygen value.

The measurement module sends the real-time blood oxygen value of the first part to the processor of the medical equipment, the processor comprehensively calculates a plurality of blood oxygen values in the time period, and then a more accurate final measured blood oxygen value can be obtained. The integrated calculation may be any conventional method, for example, an average value of the measured blood oxygen values may be calculated. .

It should be noted that, when obtaining the detection result may require a plurality of measurement processes, each measurement process may obtain the real-time blood oxygen value, the blood oxygen trend graph and the target blood oxygen value of the first portion, and therefore, the data in different measurement processes may be distinguished by using the numerical labels. For example, the real-time blood oxygen value in this step may be referred to as a first real-time blood oxygen value, the blood oxygen trend graph may be referred to as a first blood oxygen trend graph, and the target blood oxygen value may be referred to as a first target blood oxygen value.

After the processor obtains the target blood oxygen value of the first part, the processor can send the target blood oxygen value to the output module for output. The output module includes, but is not limited to, an audio module, a display, and the like.

In order to prompt the medical staff about the time point of the current measurement, when the target blood oxygen value is output, the measurement time point of the target blood oxygen value can be output. The measurement time point may be a start time point of the preset time period, an end time point of the preset time period, or a certain time point within the preset time period.

In one implementation, the display outputs the obtained information through the detection interface. Still another example of a detection interface is shown in FIG. 3C. As shown in fig. 3C, the detection interface includes a first area 321, a second area 322, a third area 323, and a fourth area 324. Wherein, the second area 322 displays the complete blood oxygen trend chart of the first part (hand) in the preset time length; the third area 323 shows the target blood oxygen value corresponding to the blood oxygen trend chart, i.e. the target blood oxygen value for the right hand is 90 (unit).

As can be seen from the above illustration, the second region and the third region in the detection interface may be further divided into a plurality of sub-regions, and the number of the sub-regions is the same as the number of the portions to be detected. To distinguish between the different sub-regions, the corresponding location of each sub-region may contain detection site identifiers, such as the words "right hand" and "foot", and/or icons representing the hands and feet, and so on.

S205: outputting third prompt information, wherein the third prompt information is used for prompting whether the blood oxygen value of the first part needs to be measured again; if yes input operation is received, returning to step S201; if a no input operation is received, step S206 is executed.

After the target blood oxygen value of the first part is obtained, if the medical staff thinks that the measurement process has factors which can affect the accuracy of the target blood oxygen value, such as severe blood oxygen fluctuation caused by large crying and screaming of the newborn, the medical staff may want to re-measure the blood oxygen value. The judgment rule of the medical staff may be the observation information of the detection object in the measurement process, or, as mentioned above, if the blood oxygen trend graph is displayed in the detection interface, the medical staff judges whether the re-measurement is needed by observing the numerical value change condition in the blood oxygen trend graph. And if the fluctuation condition of the blood oxygen trend graph is not in the preset normal fluctuation range, automatically generating prompt information to prompt that the measurement result of the medical staff is abnormal, and starting the subsequent steps after receiving the re-measurement operation triggered by the medical staff. Still alternatively, the medical device may not generate the prompt message but directly start the subsequent step.

In order to meet the retest requirement of the medical staff, prompt information can be output, and in order to distinguish the prompt information from other prompt information, the prompt information can be called as third prompt information. The output module of the third prompt message may include, but is not limited to, an audio module, a display, and the like.

Taking the above-mentioned fig. 3C as an example, the first area 321 displays the prompt text "whether the measurement is completed and the re-measurement is needed", and the fourth area 324 includes the corresponding operation buttons, "confirm the measurement this time" and "re-measure", respectively. After the user triggers the button for confirming the measurement, the subsequent step of measuring the blood oxygen value of the second part can be executed; if the user triggers the button for re-measurement, the above steps S201-305 need to be re-executed.

It should be noted that, in the following steps S206-S210, the blood oxygen value of the second portion is measured, and the relevant description can refer to the above steps S201-S205, which is not repeated herein.

S206: and outputting fourth prompt information, wherein the fourth prompt information comprises operation contents and/or cautionary matters before the blood oxygen value measurement is carried out on the second part.

Wherein the second part is a detection part other than the first part involved in the determination rule. For example, the first location may be a hand, and the second location may be a foot.

In one example, the fourth prompt message is output through a detection interface, see fig. 3D, which shows yet another example of a detection interface. As shown in fig. 3D, the detection interface includes a first region 331, a second region 332, a third region 333, and a fourth region 334. The first area 331 includes the prompt text "please connect the blood oxygen probe to the infant's foot, and start measuring after the infant is quiet". In addition, the second area 332 contains the blood oxygen trend graph in the second area 322 of fig. 3C.

S207: the method comprises the steps of obtaining a real-time blood oxygen value of a second part acquired within a preset time period, generating a blood oxygen trend graph based on the real-time blood oxygen value, and outputting the blood oxygen trend graph.

S208: and outputting fifth prompt information, wherein the fifth prompt information comprises related information and/or cautionary matters in the process of measuring the blood oxygen value of the second part.

In one example, the blood oxygen trend map of the second site and the fifth prompt message are output through a detection interface, see fig. 3E, which shows yet another example of a detection interface. As shown in fig. 3E, the detection interface includes a first region 341, a second region 342, a third region 343, and a fourth region 344.

The first area 341 displays the prompt text "in measuring, please keep the baby as quiet as possible! ", and a countdown progress bar is displayed. Specifically, the duration of the progress bar is 40s of the preset time period, and the prompt text "remaining 25 s" is displayed.

Assuming that the second portion is a foot, in addition to the blood oxygen trend map of the hand of the first portion, the blood oxygen trend map of the foot is displayed in the second area 342. According to the countdown of the progress bar, the blood oxygen trend graph is obtained after the measurement duration is 15 seconds.

S209: and obtaining a target blood oxygen value of the second part based on the real-time blood oxygen value of the second part, calculating a difference value between the blood oxygen value of the first part and the target blood oxygen value of the second part, and outputting the target blood oxygen value and the difference value of the second part.

The difference between the target blood oxygen values of the two detection sites is determined because the difference between the two detection results is required in the determination rule. If the difference value is output in the mode of detecting the interface, in order to perform reminding, a display mode for reminding can be set for the difference value, such as adding background color and the like.

S210: outputting sixth prompt information, wherein the sixth prompt information is used for prompting whether the blood oxygen value of the second part needs to be measured again; if yes input operation is received, returning to step S206; if a no input operation is received, step S211 is performed.

In one example, the target blood oxygen value, the difference value, and the sixth prompt message for the second site are output through a detection interface, see fig. 3F, which shows yet another example of a detection interface. As shown in fig. 3F, the detection interface includes a first region 351, a second region 352, a third region 353, and a fourth region 354.

The first region 351 displays the prompt text "measurement is completed and re-measurement is necessary", and the fourth region 354 includes operation buttons, "confirm this measurement" and "re-measurement", respectively. After the user triggers the button for confirming the measurement, the subsequent second blood oxygen value measurement steps of the two parts can be executed; if the user triggers the button for re-measurement, the above steps S206-S210 need to be re-executed.

The second area 352 shows the complete blood oxygen trend graph for a predetermined time period, the third area 353 shows the target blood oxygen value of 93% (in%) for a sufficient time period, and the difference between the target blood oxygen values of 3% (in%). The header corresponding to the difference 3 may contain a prompt icon, such as "Δ SpO 2", SpO2 indicating the blood oxygen saturation level. The background area of the difference 3 may be filled with a background color.

S211: judging the target blood oxygen value of the first part, the target blood oxygen value of the second part and the difference value of the two according to a judgment rule, and if a detection result is obtained, executing step S212 to output first result information or second result information; if a suspected preliminary result is obtained, step S213 is executed.

As shown in fig. 1, in some cases, the determination rule may obtain the target detection result directly according to the target blood oxygen value of the first portion, the target blood oxygen value of the second portion, and the difference between the two. But in some cases it is necessary to go through several measurements, for example three times.

S212: and outputting the first result information or the second result information.

The output may be made by various means such as audio or display. In one example, the detection result may be displayed in the third area through the above-mentioned detection interface output provided by the display. If the first result information is output, for the accuracy of the result, the recommendation information of other measuring modes such as the heart color Doppler ultrasound can be output so as to accurately check the detected object.

S213: and determining the starting time point of the second measurement, and outputting seventh prompt information, wherein the seventh prompt information is used for prompting timing from the starting time point of the second measurement.

And determining the starting time point of the second measurement according to the generating time point of the preliminary result and the measurement interval duration in the judgment rule. And generating seventh prompt information in a prompt text mode, a timing progress bar mode and the like, and outputting the seventh prompt information.

It should be noted that the timing prompt may not be executed all the time, but is started when the timing enters a shorter time range. It should be noted that, in practical applications, after the timing enters a shorter duration range, if the current interface of the medical device may not be the detection interface, an eighth prompt message may be generated, where the eighth prompt message is used to prompt to switch the current interface to the detection interface, or prompt the medical staff to perform the second measurement process.

For example, the timer counts 1 hour, and the presentation is started when 0.5 hour is entered. If the timing is prompted by voice, the timing can be prompted not continuously but according to a preset time interval. If timing is prompted by a display, and more particularly, the above-described detection interface prompt provided by the display, see FIG. 3G, which shows yet another example of a detection interface.

As shown in fig. 3G, the detection interface includes a first region 361, a second region 362, a third region 363, and a fourth region 364. Wherein, a countdown progress bar and a prompt text of '30 min left from next measurement' are displayed in the first area 361, and min is min; the fourth region 364 displays an operation button for "start measurement" that is not triggerable.

The timer indicated by the seventh indication information may control a control button for indicating the start of measurement. Specifically, when the timing does not meet the preset duration range, the control button is in an inoperable state; and when the timing meets the preset duration range, switching the control button into an operable state. For example, the preset time period ranges from 10 minutes. The mode can remind medical staff in time that the timing is about to be finished and prompt the medical staff to prepare for starting measurement in advance.

As shown in fig. 3H, the first region in the detection interface contains the prompt text "10 min left from the next measurement", and the operation button for starting measurement in the fourth region is switched from the inoperable state shown in fig. 3G to the operable state.

S214: if the measurement step is not executed after the second measurement starting time point is reached, outputting eighth prompt information, wherein the eighth prompt information is used for prompting whether to give up the first measurement result or not; if an input operation of discarding the first measurement result is received, step S215 is performed; if an input operation of retaining the first measurement result is received, the process returns to step S201.

In practical application, a second measurement process may not be started in time due to carelessness of medical staff and the like, and when measurement is needed, the interval duration between different measurement processes specified by a judgment rule is found to be exceeded. In this case, the medical staff may be given the option to continue to start the second measurement and retain the first measurement if the timeout is not long; if the timeout is too long, it may discard the first measurement and resume performing the first measurement procedure.

As shown in FIG. 3I, a first field 371 in the detection interface indicates that the text "timeout and re-measurement is required" is included, and a fourth field 374 is provided with two operation buttons, "continue measurement" and "re-measurement", respectively. The second area 372 is used for displaying the blood oxygen trend chart, and the third area 373 is used for displaying the blood oxygen measurement result (refer to the above description).

S215: the first measurement result is deleted and the process returns to step S201.

In practical applications, the prompt text included in each detection interface of the present application is not limited to the illustration, and may be other contents having the same prompt function.

According to the technical scheme, in the detection process, the medical equipment can provide prompt information with a guiding function for each measurement step, the prompt information comprises operation contents and/or notice associated with the two blood oxygen measurement signal acquisition processes of the detection object, the prompt information can further guide an operator to complete a complete detection process, the influence of human control factors of the operator on the detection result is reduced, the detection operation of the operator is assisted, and the operator experiences better.

It should be noted that, in the above detection procedure, the related information of the first part and the second part, such as the target blood oxygen value, the prompt icon, the blood oxygen trend graph, etc., may use different display modes for differentiation. The display style may include, but is not limited to, color. In addition, the respective prompt messages may not all appear in the same detection flow, and in practical applications, the detection flow may include any one or a combination of more than one of the above prompt messages.

In the above description, the detection process based on the single blood oxygen detection channel is described, it can be known that there may be a plurality of blood oxygen detection channels of the medical device, and in this case, the detection process may also be implemented based on the dual blood oxygen detection channels. This detection procedure will be mainly described below.

See fig. 4, which illustrates an example of a detection procedure based on dual blood oxygen detection channels. As shown in FIG. 4, the process may include the following steps S401 to 410.

S401: and outputting first prompt information, wherein the first prompt information comprises operation contents and/or cautionary matters before the blood oxygen value measurement is carried out on the first part and the second part.

The medical device is provided with at least two blood oxygen detection channels, and the two blood oxygen detection channels can simultaneously carry out blood oxygen measurement on the first part and the second part. Before the detection, the medical device may output a prompt message through the output module, and the description about the prompt message may refer to the description of step S201, which is not described herein again.

In one example, a medical device outputs first prompt information through a detection interface. As shown in fig. 5A, the detection interface includes a first area 501, a second area 502, a third area 503, and a fourth area 504. Wherein the first area 501 displays the prompt text "please connect the blood oxygen probe to the right hand and foot of the infant, respectively, and click to start the measurement after the infant is quiet".

The third area 503 is used to display the target blood oxygen values of the first part and the second part, and because the two blood oxygen values are not obtained currently, a prompt text "no measurement result" may be displayed in the third area to prompt the medical staff that the measurement operation is not performed yet. It should be noted that the display color of the prompt text may be lighter to avoid obstructing the observation of other contents. The second area 502 and the fourth area 504 temporarily do not display content.

S402: the method comprises the steps of acquiring real-time blood oxygen values of a first part and a second part acquired within a preset time period, generating respective blood oxygen trend graphs based on the respective real-time blood oxygen values, and outputting two blood oxygen trend graphs.

S403: and outputting second prompt information, wherein the second prompt information comprises related information and/or cautionary matters in the process of measuring the blood oxygen value of the first part and the second part.

Different from the process shown in fig. 2, the process can simultaneously obtain the blood oxygen values measured by the two blood oxygen detection channels, and simultaneously obtain the blood oxygen trend graphs of the two detection sites.

In one example, the display outputs the blood oxygen trend graph and the second prompt message through the detection interface. Referring to the test interface shown in FIG. 5B, the first field 511 displays the prompt text "measure, please keep the baby as quiet as possible". The second area 512 outputs the blood oxygen trend chart of the hand and the foot. The third region 513 and the fourth region 514 temporarily do not have display contents.

S404: and respectively obtaining respective target blood oxygen values based on the real-time blood oxygen values of the first part and the second part, calculating a difference value between the two target blood oxygen values, and outputting the target blood oxygen value and the difference value.

S405: outputting third prompt information, wherein the third prompt information is used for prompting whether the blood oxygen values of the first part and the second part need to be measured again; if yes input operation is received, returning to step S401; if a no input operation is received, step S406 is performed.

In one example, the display outputs two target blood oxygen values, a difference between the two target blood oxygen values, and a third prompt message through the detection interface. One version of a detection interface is shown in fig. 3F.

S406: judging the target blood oxygen value of the first part, the target blood oxygen value of the second part and the difference value of the two according to a judgment rule, and executing a step S407 if the first result information or the second result information is determined to be required to be output; if a suspected preliminary result is obtained, step S408 is executed.

S407: and outputting the first result information or the second result information.

S408: and determining the starting time point of the second measurement, and outputting fourth prompt information, wherein the fourth prompt information is used for prompting timing from the starting time point of the second measurement.

In one example, the display outputs the fourth prompt message through the detection interface. One version of the detection interface is shown in fig. 3G and 3H.

S409: if the measurement step is not executed after the second measurement starting time point is reached, outputting fifth prompt information, wherein the fifth prompt information is used for prompting whether to give up the first measurement result or not; if an input operation of discarding the first measurement result is received, performing step S410; if an input operation of retaining the first measurement result is received, the process returns to step S401 to obtain a detection result.

S410: the first measurement result is deleted and the process returns to step S401.

As can be seen from the determination rule, the positive or negative detection result can be obtained in step S407 after two or three measurements. Referring to the detection interface shown in FIG. 5C, the third region 523 includes three measurement results measured at the measurement time points 06:52, 07:30, and 08:02, wherein the three measurement results are 90% for right-hand SpO2 and 93% for foot SpO2, and the difference is 3 (%); the first field 521 shows the text "positive is suspected, suggesting a heart color burst". To highlight the test results, a background color may be added for "suspected positive". Of course, the "suspicion of positive" here is only one example of monitoring result information.

As can be seen from the above, the dual blood oxygen detection process shown in FIG. 4 is based on a plurality of blood oxygen detection channels. It should be noted that, if the medical device includes a plurality of blood oxygen detection channels, in practical applications, which detection procedure is executed may be determined according to the number of detection channels used, that is, how many detection channels have blood oxygen related signals measured in the interfaces. That is, the detection flow can be automatically switched according to the number of the detection channels used. Alternatively, the user may input information for selecting which detection flow is selected through an input device, and the detection flow to be executed is determined based on the selection information of the user.

Further, in order to provide more detection reference information to the medical staff, various measurement information may be output. For example, when displaying the blood oxygen trend graph, any one or more of the plethysmograph, real-time blood oxygen value and perfusion index of the detection part can be displayed together. The information of the real-time blood oxygen waveform and the perfusion index can be used for judging the quality of the detection signal.

Referring to the detection interface shown in fig. 6, the second area 612 displays the blood oxygen trend graph of the right hand and the foot, as well as the blood oxygen waveform graph pleth, the real-time blood oxygen value SpO2, and the perfusion index PI (PI). Wherein the real-time blood oxygen value SpO2 of the right hand is 98%, and the perfusion index PI is 1.3; the real-time blood oxygen value SpO2 was 94% and the perfusion index PI was 1.0.

It should be noted that in some embodiments, the detection interface may be the entire display interface of the medical device display, and in other embodiments, the detection interface may be suspended or embedded in a window on a display interface of the medical device display.

The application provides medical equipment, and single blood oxygen detection process and two blood oxygen detection processes thereof can be applied to the detection of serious congenital heart disease.

In any application scenario, the implementation steps can be summarized as the following procedures, regardless of the single blood oxygen detection procedure or the dual blood oxygen detection procedure.

A first oximetry signal measured by at least one light sensor from a first body part of a subject and a second oximetry signal measured from a second body part of the subject are obtained. And obtaining a corresponding first blood oxygen saturation value and a corresponding second blood oxygen saturation value based on the first blood oxygen measurement signal and the second blood oxygen measurement signal respectively.

Determining to output the first result information to one of the following conditions: the first blood oxygen saturation value or the second blood oxygen saturation value is smaller than a first threshold value; the obtained first blood oxygen saturation value and the second blood oxygen saturation value are located between a first threshold value and a second threshold value; the absolute value of the difference value of the obtained first blood oxygen saturation value and the obtained second blood oxygen saturation value is larger than a third threshold value; wherein the first threshold is less than the second threshold.

Specifically, the light sensor may also output a prompt to guide the operator in what manner to begin measuring the oximetry signal prior to acquiring the oximetry signal. The starting modes of different detection processes are different, and the content of the prompt message is also different. Therefore, before outputting the prompt information, it is determined whether to output the first prompt information or the second prompt information according to the selection information input by the operator or according to the determined number of the light sensors. Wherein the number of light sensors is determined according to the number of light sensor interfaces with input signals in the light sensor interfaces connected with the medical equipment.

The first prompt information is a guiding operation for collecting blood oxygen measurement signals of two body parts of the detection object by adopting the same optical sensor. Specifically, an indication is output directing the operator to attach a light sensor to a first body part of the subject, and after the first oximetry signal is obtained, an indication is output directing the operator to attach a light sensor to a second body part of the subject. One implementation manner of determining that the first oximetry signal is complete is to acquire the oximetry signal of a preset time length, for example, acquiring the oximetry signal of 30 seconds.

The second prompt message is a guiding operation for simultaneously acquiring blood oxygen measurement signals of two body parts of the detection object by respectively adopting the first optical sensor and the second optical sensor. Specifically, an instruction directing the operator to connect the first light sensor to a first body part of the detection object and an instruction directing the operator to connect the second light sensor to a second body part of the detection object are output.

For example, as shown in the dual blood oxygen detection process, the light sensor may obtain the first blood oxygen measurement signal and the second blood oxygen measurement signal at the same time, and as shown in the single blood oxygen detection process, the light sensor may also obtain the first blood oxygen measurement signal and the second blood oxygen measurement signal at two times, respectively. The two different oximetry signals are signals measured from two different body parts and are referred to as a first oximetry signal and a second oximetry signal for ease of distinction.

The displayed graph of the first oximetry signal, such as the waveform diagram, and the displayed graph of the second oximetry signal, such as the waveform diagram, may be displayed in the detection interface.

The first blood oxygen saturation value can be obtained according to the first blood oxygen measurement signal, such as the blood oxygen value of the lower limb, and the second blood oxygen saturation value can be obtained according to the second blood oxygen measurement signal, such as the blood oxygen value of the upper limb. One calculation method is that a plurality of groups of blood oxygen saturation values are obtained based on the first blood oxygen measurement signal, and the average value of the plurality of groups of blood oxygen saturation values is used as the first blood oxygen saturation value; and obtaining a plurality of groups of blood oxygen saturation values based on the second blood oxygen measurement signal, and taking the average value of the plurality of groups of blood oxygen saturation values as the second blood oxygen saturation value. For example, multiple sets of blood oxygen values of the lower limb can be obtained within 30 seconds, and the average value of the multiple sets of blood oxygen values of the lower limb is calculated as the blood oxygen value of the lower limb; multiple sets of blood oxygen values of the hands can be obtained within 30 seconds, and the average value of the multiple sets of blood oxygen values of the hands is calculated as the blood oxygen value of the hands.

The two blood oxygen saturation values may obtain the first result information if one of the above conditions is satisfied, wherein the first result information indicates a positive result. Outputting first result information to prompt an operator that a result of the detection object is positive. Of course, the first result information is not limited to the positive result, and the blood oxygen value and/or the difference between the blood oxygen values of the two sites may be displayed as the first result information.

It should be noted that the first blood oxygen saturation value and the second blood oxygen saturation value may be a set of parameter values obtained by one measurement, or may be a plurality of sets of parameter values obtained by multiple measurements. Specifically, in some cases, the result information may be obtained by only one set of parameter values obtained in one measurement process, but in some cases, the result information is obtained by not obtaining the result information by using the lower limbs of the one set of parameter values obtained in one measurement process, and the final result information is obtained by comprehensively judging a plurality of sets of parameter values obtained in a plurality of measurement processes.

As shown in fig. 1, if a group of parameter values obtained in the first measurement process satisfies the following condition that the first blood oxygen saturation value or the second blood oxygen saturation value is smaller than the first threshold, the first result information may be directly output; or, the first blood oxygen saturation value or the second blood oxygen saturation value is larger than or equal to the second threshold, and the absolute value of the difference value between the first blood oxygen saturation value and the second blood oxygen saturation value is smaller than or equal to the third threshold, so as to directly output the second result information. Therefore, the parameter value obtained by the first measurement can directly obtain the result information without subsequent measurement as long as the parameter value meets the above conditions. In order to distinguish this condition from other conditions, the above condition may be referred to as a first condition.

However, if the first set of parameter values does not satisfy the first condition, but satisfies a second condition, i.e., the first blood oxygen saturation value and the second blood oxygen saturation value are between the first threshold and the second threshold; or, if the absolute value of the difference between the first blood oxygen saturation value and the second blood oxygen saturation value is greater than the third threshold, a second measurement process is required.

If a group of parameter values obtained in the second measurement process also meet the first condition, result information can be directly obtained without performing a third measurement process. If a set of parameter values obtained in the second measurement process satisfies the second condition, a third measurement process is required. A set of parameter values obtained in the third measurement process may also obtain result information according to the above conditions, it should be noted that the judgment rule shown in fig. 1 measures three times at most, and if the set of parameter values obtained in the third measurement process still satisfies the second condition, the fourth measurement is not needed, and the first result information is directly output.

As can be seen from the above description, the result information may be obtained from one measurement process or may be obtained from a plurality of measurement processes in the case that certain conditions are satisfied.

The following description focuses on how the first result information and the second result information are obtained.

No matter there are several groups of parameter values, as long as the first blood oxygen saturation value or the second blood oxygen saturation value in a certain group of parameter values is smaller than the first threshold value, the first result information can be obtained; or, in some cases, the first blood oxygen saturation value and the second blood oxygen saturation value in a certain set of parameter values are between the first threshold value and the second threshold value; alternatively, in some cases, the absolute value of the difference between the first blood oxygen saturation value and the second blood oxygen saturation value in a certain set of parameter values is greater than the third threshold, and the first result information may also be obtained.

More specifically, if the first blood oxygen saturation value and the second blood oxygen saturation value are between the first threshold and the second threshold, or if the absolute value of the difference between the first blood oxygen saturation value and the second blood oxygen saturation value is greater than the third threshold, then other measured blood oxygen saturation values are also needed to assist in obtaining the result information. Further, a prompt message indicating that the operator is directed to start measurement again after a preset time period, such as a prompt message measured again after 1 hour, is output.

Based on the prompt message, the first blood oxygen saturation value and the second blood oxygen saturation value of the second group, and the first blood oxygen saturation value and the second blood oxygen saturation value of the third group are obtained.

The first result information can be obtained when all three sets of parameter values satisfy the condition that the first blood oxygen saturation value and the second blood oxygen saturation value are between the first threshold and the second threshold, or all satisfy the condition that the absolute value of the difference value between the first blood oxygen saturation value and the second blood oxygen saturation value is greater than the third threshold.

Of course, if the first blood oxygen saturation value or the second blood oxygen saturation value in the second set of parameter values is smaller than the first threshold value, the first result information, i.e. the positive result, may also be directly output. Similarly, if the third set of parameter values satisfies the condition, the first result information is also directly output.

However, if the second set of parameter values simultaneously satisfies the following two conditions, i.e. the first blood oxygen saturation value or the second blood oxygen saturation value is greater than or equal to the second threshold value, and the absolute value of the difference between the first blood oxygen saturation value and the second blood oxygen saturation value is less than or equal to the third threshold value, the second result information is outputted. Likewise, the third set of parameter values satisfies the two conditions, and second result information is also output. As a result, the two conditions, which are the judgment conditions of the second result information, are satisfied, and the second result information can be obtained.

In practical applications, the blood oxygen detection channel may be a wired channel, and the connected detection module may be a blood oxygen probe. Of course, the blood oxygen detection channel may also be a wireless channel, and the detection module used may be a wireless blood oxygen sensor, such as a wireless blood oxygen light sensor. The wireless blood oxygen sensor can be remotely controlled by a processor of the medical equipment, and after receiving the measurement starting signal, the wireless blood oxygen sensor starts to measure the blood oxygen value of the first part and/or the second part of the detection object and sends the obtained blood oxygen value to the processor of the medical equipment. The measurement starting signal may include the measurement duration, or the measurement duration may be recorded in the wireless blood oxygen sensor.

The wireless blood oxygen sensor can be provided with an acoustic-optical module to prompt the working state of the wireless blood oxygen sensor in an acoustic-optical mode. For example, the wireless blood oxygen sensor may generate an audible and visual prompt when receiving a measurement start signal, completing the measurement of the blood oxygen value, completing the transmission of the blood oxygen value, or causing an abnormality in the connection position between the sensor and the detection object. Different forms of sound and light can be output under different conditions to prompt different conditions.

The wireless blood oxygen sensor can send the blood oxygen value to the medical equipment main body in various wireless modes, such as WI-FI, radio frequency, Bluetooth, Internet of things and the like.

The detection process provided by the application can be applied to other scenes besides blood oxygen detection. In any application scenario, the detection module may be a wireless sensor, and may be remotely controlled by the medical device. Specifically, the method comprises the following steps:

the medical device sends a measurement starting instruction to the wireless light sensor, the wireless light sensor starts measurement based on the measurement starting instruction, and provides reminding information indicating that the wireless light sensor is measuring, for example, the photoelectric module outputs flashing light to indicate that the wireless light sensor is measuring.

After the medical equipment judges that the first blood oxygen measurement signal and/or the second blood oxygen measurement signal are/is obtained, a measurement ending instruction is sent to the wireless optical sensor, the wireless optical sensor finishes measurement based on the measurement ending instruction, and a reminding message indicating that the wireless optical sensor finishes measurement is provided, for example, the photoelectric module outputs red normally-bright light to indicate that the wireless optical sensor finishes measurement. In another implementation, the wireless light sensor may automatically end the measurement based on its own setting information, such as the measurement time length information.

It should be noted that the processor is also configured to perform all the steps and operations related to the processing.

The processor 702 may be a central processing unit CPU, or an Application Specific Integrated Circuit (ASIC), or one or more Integrated circuits configured to implement embodiments of the present application.

Furthermore, the present application also provides a readable storage medium, on which a computer program is stored, which, when executed by a processor, implements the detection method of any one of the above medical devices.

When the medical device is a monitor, a specific example of the monitor is shown in fig. 8. FIG. 8 provides a system diagram of a parameter processing module in a multi-parameter monitor.

The multi-parameter monitor has a separate housing with a sensor interface area on the housing panel, in which a plurality of sensor interfaces are integrated for connecting with external physiological parameter sensor accessories 811, a small IXD display area, a display 818, an input interface circuit 820, and an alarm circuit 819 (e.g., an LED alarm area). The parameter processing module is used for communicating with the host and getting electricity from the host, and is used for an external communication and power interface. The parameter processing module also supports an external parameter insertion module, a plug-in monitor host can be formed by inserting the parameter insertion module and is used as a part of the monitor, the plug-in monitor host can also be connected with the host through a cable, and the external parameter insertion module is used as an external accessory of the monitor. In addition, the multi-parameter monitor includes a memory 817 for storing various data generated during the computer program and associated monitoring process.

The internal circuit of the parameter processing module is disposed in the housing, as shown in fig. 8, and includes a signal acquisition circuit 812, a front-end signal processing circuit 813, and a main processor 815 corresponding to at least two physiological parameters.

The main processor 815 may implement the various process-related steps of the various apnea event monitoring methods described above.

The signal collecting circuit 812 can be selected from an electrocardiograph circuit, a respiration circuit, a body temperature circuit, a blood oxygen circuit, a non-invasive blood pressure circuit, an invasive blood pressure circuit, etc., the signal collecting circuits 812 are respectively electrically connected with corresponding sensor interfaces for being electrically connected to sensor accessories 811 corresponding to different physiological parameters, the output end of the signal collecting circuit is coupled to the front end signal processor, the communication port of the front end signal processor is coupled to the main processor, and the main processor is electrically connected with an external communication and power interface.

The various physiological parameter measuring circuits can adopt a common circuit in the prior art, a front-end signal processor completes the sampling and analog-to-digital conversion of the output signal of the signal acquisition circuit and outputs a control signal to control the measuring process of the physiological signal, and the parameters include but are not limited to: electrocardio, respiration, body temperature, blood oxygen, noninvasive blood pressure and invasive blood pressure parameters.

The front-end signal processor may be powered by an isolated power supply, and the sampled data may be sent to the host processor via an isolated communication interface after being simply processed and packaged, for example, the front-end signal processor circuit may be coupled to the host processor 815 via the isolated power supply and communication interface 814.

The reason that the front-end signal processor is supplied with power by the isolation power supply is that the DC/DC power supply is isolated by the transformer, which plays a role in isolating the patient from the power supply equipment, and mainly aims at: 1. isolating the patient, and floating the application part through an isolation transformer to ensure that the leakage current of the patient is small enough; 2. the voltage or energy when defibrillation or electrotome is applied is prevented from influencing board cards and devices of intermediate circuits such as a main control board and the like (guaranteed by creepage distance and electric clearance).

The main processor completes the calculation of the physiological parameters and sends the calculation results and waveforms of the parameters to a host (such as a host with a display, a PC, a central station, etc.) through an external communication and power interface 816, wherein the external communication and power interface 816 may be one or a combination of an Ethernet (Ethernet), a Token Ring (Token Ring), a Token Bus (Token Bus), and a local area network interface formed by a backbone Fiber Distributed Data Interface (FDDI) of the three networks, and may also be one or a combination of wireless interfaces such as infrared, bluetooth, wifi, WMTS communication, or may also be one or a combination of wired data connection interfaces such as RS232, USB, etc.

The external communication and power interface 816 may also be one or a combination of a wireless data transmission interface and a wired data transmission interface. The host can be any computer equipment of a host computer of a monitor, an electrocardiograph, an ultrasonic diagnostic apparatus, a computer and the like, and matched software is installed to form the monitor equipment. The host can also be communication equipment such as a mobile phone, and the parameter processing module sends data to the mobile phone supporting Bluetooth communication through the Bluetooth interface to realize remote transmission of the data.
