Description

Technical Field

[0001] This invention relates to the field of neonatal care, and in particular to an auxiliary warning system for neonatal respiratory assessment that utilizes an automated system architecture to continuously monitor and determine the degree of respiratory distress in newborns, and to issue an immediate alarm to medical staff when respiratory distress occurs, so as to facilitate the rapid execution of relevant medical procedures by medical staff. Prior Technology

[0002] For newborns, nursing staff in relevant departments have many care items that need to be performed and closely monitored, such as checking the newborn's breathing status, controlling the newborn's body temperature, observing jaundice, and monitoring urination and defecation, to ensure the newborn's healthy growth and safety. Among these, the newborn's breathing status is an item that requires very careful attention.

[0003] Neonatal respiratory distress syndrome (NRS) is a leading cause of neonatal death, and a key factor contributing to its development is a lack of sufficient surfactant in the lungs. Surfactants are substances produced within the alveoli that reduce alveolar surface tension to prevent collapse during exhalation. Currently, in neonatal wards, nurses can only assess respiratory distress by visually observing a newborn's breathing and physical appearance. However, in neonatal wards, each nurse is currently caring for multiple newborns simultaneously, creating significant challenges in monitoring their breathing. First, when nurses care for multiple newborns, it is difficult to frequently observe the breathing status of each newborn. This may lead to early signs of respiratory distress not being detected in time, delaying treatment. In addition to clinical nursing duties, nurses also have to handle a large amount of paperwork. During busy shifts, it is easy to not be able to devote enough time and energy to the observation and care of newborns. Furthermore, such a high workload can also affect the nurses' attention and focus, causing them to become exhausted and reduce their sensitivity to abnormal situations. Finally, for less experienced new nurses, they may not have sufficient ability to identify neonatal respiratory distress, which may lead to failure to deal with the situation in a timely manner.

[0004] Therefore, it is clear that respiratory status is a crucial and vital aspect of neonatal life, but since neonatal respiratory status can only be observed manually, this method can easily lead to unfortunate consequences in demanding medical environments. In view of this, our invention team has conceived and proposed an auxiliary alert system for neonatal respiratory assessment, hoping to alleviate the monitoring burden on nursing staff and automatically monitor and assess the neonatal respiratory status in real time, promptly alerting nursing staff to any potential respiratory distress so that appropriate treatment can be administered quickly. Summary of the Invention

[0005] The main objective of this invention is to provide an auxiliary alert system for neonatal respiratory assessment. This system continuously monitors the neonatal state by capturing images and sound, automatically judges the captured monitoring information, and determines the degree of respiratory distress of the neonatal through a scoring method. In the event of a dangerous situation, it can immediately notify nursing staff to take corresponding measures, reducing the chance of negligence or misjudgment that may have been caused by relying on manual observation in the past. This aims to effectively assist nursing staff in performing neonatal care tasks, reduce the workload of nursing staff, and improve the quality of neonatal care.

[0006] To achieve the above objectives, the present invention discloses an auxiliary alert system for neonatal respiratory assessment, for real-time interpretation of a newborn's respiratory status, comprising: a detection device including: a first image monitor, disposed on the left or right side of the newborn and having a first monitoring range, for recording information on the newborn's chest movement and intercostal retraction status within the first monitoring range; a second image monitor, disposed above the newborn and having a second monitoring range, for recording information on the newborn's xiphoid process retraction and nasal flaring status within the second monitoring range; and a stethoscope monitor, attached to the newborn's chest, for recording information on the intensity of the newborn's respiratory sounds; and a feature standard database for storing... The system includes a first respiratory information standard, a second respiratory information standard, a third respiratory information standard, a fourth respiratory information standard, and a fifth respiratory information standard; a processing device electrically connected to the detection device and the feature standard database, for receiving information on chest movement, intercostal retraction, xiphoid retraction, nasal ala expansion, and respiratory sound intensity, and further determining the degree of respiratory distress in the newborn according to the first, second, third, fourth, and fifth respiratory information standards; wherein the first respiratory information standard has a first respiratory distress weak level, a first respiratory distress medium level, and a first respiratory distress level... After assessing the severity of respiratory distress, the results are as follows: when the newborn's chest movement information, compared to the first respiratory information standard, shows a simultaneous upward and downward movement, it is judged to be at the weak level of the first respiratory distress; when the newborn's chest movement information shows a delayed, asynchronous upward and downward movement, it is judged to be at the moderate level of the first respiratory distress; when the newborn's chest movement information shows an opposite upward and downward movement, it is judged to be at the strong level of the first respiratory distress. A score of 0 is given for the weak level, 1 for the moderate level, and 2 for the strong level. The second respiratory information standard has a second... The assessment results for three levels of respiratory distress—weak, moderate, and severe—are as follows: If the intercostal retraction of the newborn is indistinct compared to the standard for second respiratory distress, it is classified as weak respiratory distress; if the intercostal retraction is clearly visible, it is classified as moderate respiratory distress; and if the intercostal retraction is clearly visible, it is classified as severe respiratory distress. The scores are 0 for weak respiratory distress, 1 for moderate respiratory distress, and 2 for severe respiratory distress.The third respiratory information standard has three levels of assessment: weak third respiratory distress, moderate third respiratory distress, and strong third respiratory distress. When the neonatal xiphoid process depression is assessed as indistinct compared to the third respiratory information standard, it is assessed as weak third respiratory distress; when the xiphoid process depression is clearly visible, it is assessed as moderate third respiratory distress; and when the xiphoid process depression is clearly visible, it is assessed as strong third respiratory distress. A score of 0 is given for those assessed as weak third respiratory distress, and a score of 0 is given for those assessed as moderate third respiratory distress. The newborn's respiratory distress level is assessed as follows: a score of 1 indicates a low level of respiratory distress, while a score of 2 indicates a high level of respiratory distress. The fourth respiratory information standard has three levels: low, moderate, and high. When the newborn's nasal flare status is assessed as not significantly dilated compared to the fourth respiratory information standard, it is considered to be at the low level of respiratory distress. When the newborn's nasal flare status is slightly visible, it is considered to be at the moderate level of respiratory distress. When the newborn's nasal flare status is clearly visible, it is considered to be at the high level of respiratory distress. The assessment then determines the level of respiratory distress based on the assessment criteria. The fourth respiratory distress level is assessed as follows: a score of 0 for the weak level, 1 for the intermediate level, and 2 for the strong level. The fifth respiratory information standard has three assessment results: a weak level, an intermediate level, and a strong level. When the newborn's respiratory sound intensity is assessed as indistinct compared to the fifth respiratory information standard, it is considered to be in the weak level; when the newborn's respiratory sound intensity is slight, it is considered to be in the intermediate level; when the newborn's respiratory sound intensity is strong, it is considered to be in the strong level. When the sound is clearly audible, the newborn is judged to be in the fifth level of severe respiratory distress. A score of 0 is given for those in the fifth level of weak respiratory distress, 1 for those in the fifth level of moderate respiratory distress, and 2 for those in the fifth level of severe respiratory distress. The processing device assesses the newborn's respiratory distress level based on the first, second, third, fourth, and fifth respiratory information standards, summing the scores to obtain a total respiratory assessment value. An alarm device is electrically connected to the processing device and receives the total respiratory assessment value. When the total respiratory assessment value exceeds a preset standard value, a first alarm notification is issued.

[0007] Preferably, the processing device further includes a frequency analysis module. After the processing device determines the chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal ala expansion status information, and respiratory sound intensity information according to the first, second, third, fourth, and fifth respiratory information standards, and determines that any one of these respiratory distress information (chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal ala expansion status information, and respiratory sound intensity information) has a respiratory distress severity score of 2, the frequency analysis module, when the number of times the respiratory distress severity score is continuously determined to be 2 exceeds a threshold value, triggers the warning device to issue a second warning notification.

[0008] Preferably, the warning device includes a display and an image unit. When the first warning notification or the second warning notification is issued, the image unit sets an indicator image for two of the following: chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound level information, based on the assessment of respiratory distress level score. The display shows one or a combination of the chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound level information, as well as the indicator image.

[0009] Preferably, the auxiliary warning system further includes a storage device electrically connected to the processing device, used to integrate and store the information on chest movement status, intercostal retraction status, xiphoid retraction status, nasal ala expansion status, and respiratory sound intensity, as well as the scores obtained by the processing device after judging the information on chest movement status, intercostal retraction status, xiphoid retraction status, nasal ala expansion status, and respiratory sound intensity according to the first respiratory information standard, the second respiratory information standard, the third respiratory information standard, the fourth respiratory information standard, and the fifth respiratory information standard, into a newborn observation information.

[0010] Preferably, the auxiliary warning system further includes a standard update module, which is electrically connected to the feature standard database and the storage device. The standard update module automatically updates the first respiratory information standard, the second respiratory information standard, the third respiratory information standard, the fourth respiratory information standard and the fifth respiratory information standard by training the newborn observation information through AI learning technology.

[0011] In summary, the neonatal respiratory assessment auxiliary warning system of this invention can monitor the respiratory status of newborns in real time through automated detection and judgment technology to avoid omissions or oversights that could lead to unfortunate events. Specifically, the auxiliary warning system automatically detects images and sounds, and judges the acquired information on chest movement, intercostal retraction, xiphoid retraction, nasal flaring, and respiratory sound intensity against a first, second, third, fourth, and fifth respiratory information standard. It then obtains a total respiratory assessment value for the newborn through a scoring method and issues an immediate warning notification when the newborn shows signs of respiratory distress, facilitating appropriate treatment by nursing staff. This system can reliably monitor and judge the respiratory status of newborns in real time, avoiding misjudgments or oversights caused by human observation, effectively reducing the workload and burden on nursing staff, thereby providing better quality care for newborns and contributing to an improved neonatal healthcare environment. Furthermore, the present invention also proposes additional technical features to enhance the effectiveness of the auxiliary warning system, the specific technical means of which are as described in the paragraphs above. Simple Explanation of the Diagram

[0012] Figure 1 is a schematic diagram of the system block of a preferred embodiment of the present invention.

[0013] Figure 2 is a schematic diagram of a system block of another preferred embodiment of the present invention. Implementation

[0014] To enable those skilled in the art to clearly understand the contents of this invention, please refer to the following description and accompanying drawings.

[0015] Please refer to Figure 1, which is a block diagram of a preferred embodiment of the present invention. The present invention discloses an auxiliary warning system 1 for neonatal respiratory assessment, which is used to instantly determine the respiratory status of a newborn, including a detection device 10, a feature standard database 11, a processing device 12 and a warning device 13.

[0016] The detection device 10 includes a first image monitor 101, a second image monitor 102, and a stethoscope monitor 103. The first image monitor 101 is positioned on the left or right side of the newborn and has a first monitoring range for recording chest movement and intercostal retraction information within that range. The second image monitor 102 is positioned above the newborn and has a second monitoring range for recording xiphoid process retraction and nasal flaring information within that range. The stethoscope monitor 103 is attached to the newborn's chest to record the intensity of the newborn's breathing sounds.

[0017] The feature standard database 11 stores a first respiratory information standard 111, a second respiratory information standard 112, a third respiratory information standard 113, a fourth respiratory information standard 114, and a fifth respiratory information standard 115. The processing device 12 is electrically connected to the detection device 10 and the feature standard database 11 to receive information on chest movement, intercostal retraction, xiphoid process retraction, nasal ala expansion, and respiratory sound intensity, and further determines the degree of respiratory distress of the newborn according to the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115.

[0018] The first respiratory information standard 111 has three levels of assessment results: a weak level of first respiratory distress, a moderate level of first respiratory distress, and a strong level of first respiratory distress. When the newborn's chest movement information shows a state of same-up and same-down movement compared to the first respiratory information standard 111, it is judged to be at the weak level of first respiratory distress; when the newborn's chest movement information shows a delayed asynchronous up and down movement, it is judged to be at the moderate level of first respiratory distress; when the newborn's chest movement information shows an up and down movement that are exactly opposite, it is judged to be at the strong level of first respiratory distress. The score is 0 for those who are judged to be at the weak level of first respiratory distress, 1 for those who are judged to be at the moderate level of first respiratory distress, and 2 for those who are judged to be at the strong level of first respiratory distress.

[0019] The second respiratory information standard 112 has three levels of assessment results: a weak level of second respiratory distress, a moderate level of second respiratory distress, and a strong level of second respiratory distress. When the intercostal retraction information of the newborn is assessed as having an indistinct retraction state compared to the second respiratory information standard 112, it is judged to be at the weak level of second respiratory distress; when the intercostal retraction information of the newborn is exactly a visible retraction state, it is judged to be at the moderate level of second respiratory distress; when the intercostal retraction information of the newborn is clearly a visible retraction state, it is judged to be at the strong level of second respiratory distress. The score is 0 for those who are judged to be at the weak level of second respiratory distress, 1 for those who are judged to be at the moderate level of second respiratory distress, and 2 for those who are judged to be at the strong level of second respiratory distress.

[0020] The third respiratory information standard 113 has three levels of assessment results: weak third respiratory distress, moderate third respiratory distress, and strong third respiratory distress. When the xiphoid process depression of the newborn is assessed as not obvious compared to the third respiratory information standard 113, it is judged to be at the weak level of third respiratory distress; when the xiphoid process depression of the newborn is exactly visible, it is judged to be at the moderate level of third respiratory distress; when the xiphoid process depression of the newborn is clearly visible, it is judged to be at the strong level of third respiratory distress. The score is 0 for those who are judged to be at the weak level of third respiratory distress, 1 for those who are judged to be at the moderate level of third respiratory distress, and 2 for those who are judged to be at the strong level of third respiratory distress.

[0021] The fourth respiratory information standard 114 has three levels of assessment results: weak fourth respiratory distress, moderate fourth respiratory distress, and strong fourth respiratory distress. When the newborn's nasal flare status information is assessed as not significantly dilated compared to the fourth respiratory information standard 114, it is judged to be at the weak fourth respiratory distress level; when the newborn's nasal flare status information is slightly visible dilated, it is judged to be at the moderate fourth respiratory distress level; and when the newborn's nasal flare status information is clearly visible dilated, it is judged to be at the strong fourth respiratory distress level. The score is 0 for those who are judged to be at the weak fourth respiratory distress level, 1 for those who are judged to be at the moderate fourth respiratory distress level, and 2 for those who are judged to be at the strong fourth respiratory distress level.

[0022] The Fifth Respiratory Information Standard 115 has three levels of assessment: weak, moderate, and strong. When the newborn's respiratory sound intensity is assessed as indistinct compared to the Fifth Respiratory Information Standard 115, it is judged to be at the weak level of fifth respiratory distress; when the newborn's respiratory sound intensity is slight, it is judged to be at the moderate level of fifth respiratory distress; and when the newborn's respiratory sound intensity is obvious, it is judged to be at the strong level of fifth respiratory distress. The score is 0 for those at the weak level, 1 for those at the moderate level, and 2 for those at the strong level. The processing device 12 assesses the newborn's respiratory distress level based on the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115, and then sums up the scores to obtain a total respiratory assessment value. The warning device 13 is electrically connected to the processing device 12 and receives the total respiratory assessment value. When the total respiratory assessment value exceeds a preset standard value, it issues a first warning notification. This preset standard value is dynamically adjustable, meaning it can be set according to the desired warning sensitivity. The warning device 13 can provide an intuitive and clear warning effect, for example, through sound or light prompts. Alternatively, the warning device 13 can be further electrically connected to a nursing host to synchronously display the first warning notification on the host.

[0023] Therefore, through this auxiliary warning system 1, the respiratory status of the newborn can be accurately and completely monitored and judged automatically, assisting nursing staff in monitoring the newborn and avoiding the regrettable situation of failing to detect respiratory distress in time due to busy work or lack of experience, thus delaying treatment. The auxiliary warning system 1 captures specific image and sound information through the detection device and automatically judges the degree of respiratory distress according to the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115. Each of the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115 defines a respiratory distress level according to different states and assigns different scores to different levels. The total respiratory assessment value is obtained by summing the scores. Finally, when the total respiratory assessment value exceeds the preset standard value, the first warning notification is issued in time so that nursing staff can quickly respond.

[0024] Furthermore, to enable caregivers to more easily monitor and provide focused care to newborns with a higher probability of respiratory distress, the processing device 12 may further include a frequency analysis module 121. After the processing device 12 determines the chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal ala expansion status information, and respiratory sound intensity information according to the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115, and determines that any one of the respiratory distress severity scores is 2, the frequency analysis module 121 will trigger the warning device 13 to issue a second warning notification when the number of times the respiratory distress severity score is continuously determined to be 2 exceeds a threshold value. Specifically, for example, if the total respiratory assessment value after the detection of a newborn's status information by the processing device 12 is not greater than the preset standard value, but a certain status information of the newborn, such as chest movement status information, is judged by the processing device 12 to have a respiratory distress score of 2 according to the first respiratory information standard, the frequency analysis module 121 will issue the second warning notification if the number of times the respiratory distress score of 2 is continuously judged by the processing device 12 after the chest movement status information is continuously judged by the processing device 12 exceeds the threshold value. For example, if the number of times the respiratory distress score of 2 is continuously judged by the processing device 12 after the chest movement status information is continuously judged by the processing device 12 is 4 times, and the threshold value is 3 times, then the warning device 13 will be activated to issue the second warning notification. Accordingly, if any of the newborn's chest movement status, intercostal retraction status, xiphoid retraction status, nasal ala expansion status, and respiratory sound intensity information is repeatedly judged to be indicative of severe respiratory distress according to the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, or the fifth respiratory information standard 115, this second warning notification will be issued to allow caregivers to pay more attention to the newborn and be vigilant for the occurrence of severe respiratory distress, thereby increasing the intensity of the warning.

[0025] Please refer to Figure 2, which is a system block diagram of another preferred embodiment of the present invention. In this embodiment, the warning device 13 includes a display 131 and an image unit 132. When the first or second warning notification is issued, the image unit 132 sets an indicator image for the respiratory distress score of two of the following: chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal ala expansion status information, and respiratory sound level information. The display 131 displays one or a combination of these information, along with the indicator image. The indicator image can be presented, for example, in a flashing manner. Accordingly, when the warning is issued, the status information of the newborn exhibiting poor breathing can be displayed on the screen simultaneously. This not only allows nursing staff to grasp the situation more quickly but also achieves teaching purposes, allowing new nursing staff and even nursing interns to accumulate experience and relevant knowledge from clinical situations. Preferably, the indicator image can be located in areas exhibiting abnormalities within the information on chest movement, intercostal retraction, xiphoid retraction, nasal flaring, or respiratory sound intensity. For example, if a newborn's intercostal retraction and nasal flaring are assessed by the processing device as having a respiratory distress score of 2, the indicator image can appear at the intercostal retraction location in the intercostal retraction information and at the nasal flaring location in the nasal flaring information. This allows the viewer to quickly identify the areas to be visually observed for these information, facilitating learning and enabling caregivers to reassess the newborn's condition. Incidentally, if the respiratory sound intensity is assessed as having a respiratory distress score of 2, the display 131 can graphically display the respiratory audio and frequency status and the indicator image, which can be marked at the location of the abnormal respiratory audio or frequency.

[0026] Furthermore, the auxiliary warning system 1 may include a storage device 14, which is electrically connected to the processing device 12. This storage device 14 is used to collect information on chest movement, intercostal retraction, xiphoid retraction, nasal flaring, and respiratory sound levels. It also includes a timestamp-stamped score of these information, calculated by the processing device 12 according to a first respiratory information standard 111, a second respiratory information standard 112, a third respiratory information standard 113, a fourth respiratory information standard 114, and a fifth respiratory information standard 115, to form a newborn observation record for storage. The auxiliary warning system 1 can centrally store the monitored newborn's condition as a corresponding information set through the storage device 14, which can be accessed by nursing staff or doctors at any time. It can also serve as learning material for new nursing staff or nursing students.

[0027] Furthermore, the auxiliary warning system 1 includes a standard update module 15, which is electrically connected to the feature standard database 11 and the storage device 14. The standard update module 15 uses AI learning technology to train the newborn observation information to automatically update the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115. After being collected and stored, the newborn observation information, in addition to having the above-mentioned uses, can also be used as AI training material to update the first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115, so that the judgment of the processing device 12 can be more accurate, thereby improving the effectiveness of the auxiliary warning. Specifically, the presentation of the newborn's chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound intensity information can be varied. The first respiratory information standard 111, the second respiratory information standard 112, the third respiratory information standard 113, the fourth respiratory information standard 114, and the fifth respiratory information standard 115, updated through AI learning and training by the standard update module 15, can cover a more diverse range of chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound intensity information corresponding to weak, medium, and strong respiratory distress levels. Through continuous intelligent learning and updating, the accuracy of judgment can be improved.

[0028] In summary, the neonatal respiratory assessment auxiliary alert system of this invention monitors the newborn's respiratory status in real time through automated detection and judgment, and issues an immediate alarm notification when respiratory distress occurs. This not only reduces the risk of misjudgment from manual observation but also effectively improves the quality of neonatal care and further reduces the workload of nursing staff. Specifically, the auxiliary alert system continuously monitors the newborn's respiratory status through automatic image and sound capture and uses a special standard scoring mechanism to determine the degree of respiratory distress. When the newborn exhibits respiratory distress, the auxiliary alert system will issue an immediate notification, allowing nursing staff to quickly take appropriate action. Furthermore, to more accurately monitor the newborn's respiratory status and enhance the alert intensity, this can be achieved through the frequency analysis module. This allows for the early issuance of alerts when a particular symptom is repeatedly assessed as indicating severe respiratory distress, enabling caregivers to confirm the newborn's condition earlier and reducing the likelihood of severe respiratory distress. Additionally, to allow caregivers to directly understand the newborn's condition, the alert device can include a display and an image unit. This allows the newborn's status to be displayed simultaneously with the alert notification, and the directional image provides quick guidance, which can also be used to train new caregivers. Furthermore, this status information can be integrated into a unique newborn database stored in the storage device for future review and learning by medical staff. Based on the development and advantages of AI technology, the auxiliary alert system can also include a standard update module to use the newborn's observation information as AI training material, thereby updating and adjusting the first to fifth respiratory standard information, making the comparison of the processing device more accurate. To reiterate, the team behind this invention possesses extensive clinical experience and professional nursing knowledge, and is well aware that for neonatal nurses, observing the respiratory status of newborns presents numerous challenges due to the medical environment, personal workload, and experience. Therefore, the team hopes to provide tools that can effectively assist nurses in resolving and improving the workload of observing the respiratory status of newborns. In addition to effectively reducing the burden and stress on nurses, this tool can also improve the quality of newborn care and effectively reduce the probability of misjudgment, aiming to provide a more friendly and high-quality medical environment for newborns and nurses.

The score is 0 for those who are judged to be in the fourth level of weak respiratory distress, 1 for those who are judged to be in the fourth level of moderate respiratory distress, and 2 for those who are judged to be in the fourth level of severe respiratory distress. The fifth respiratory information standard has three levels of assessment: weak respiratory distress, moderate respiratory distress, and strong respiratory distress. When the newborn's respiratory sound intensity information is assessed as having indistinct breathing sounds compared to the fifth respiratory information standard, it is judged to be at the weak respiratory distress level; when the newborn's respiratory sound intensity information shows a slight breathing sound, it is judged to be at the moderate respiratory distress level; and when the newborn's respiratory sound intensity information shows a significant breathing sound, it is judged to be at the strong respiratory distress level. The score is 0 for those at the weak respiratory distress level, 1 for those at the moderate respiratory distress level, and 2 for those at the strong respiratory distress level. The processing device assesses the newborn's respiratory distress level based on the first, second, third, fourth, and fifth respiratory information standards, summing the scores to obtain a total respiratory assessment value. An alarm device is also included, electrically connected to the processing device and receiving the total respiratory assessment value. When the total respiratory assessment value exceeds a preset standard value, a first alarm notification is issued.

2. The auxiliary warning system as described in claim 1, wherein, The processing device further includes a frequency analysis module. After the processing device determines the chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound intensity information according to the first respiratory information standard, the second respiratory information standard, the third respiratory information standard, the fourth respiratory information standard, and the fifth respiratory information standard, and determines that the respiratory distress level score of any one of the chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound intensity information is 2, the frequency analysis module drives the warning device to issue a second warning notification when the number of times the respiratory distress level score is continuously judged as 2 exceeds a threshold value.

3. The auxiliary warning system as described in claim 2, wherein, The warning device includes a display and an image unit. When the first warning notification or the second warning notification is issued, the image unit sets an indicator image for two of the following: chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound level information, based on the assessment of respiratory distress level. The display shows one or a combination of the chest movement status information, intercostal retraction status information, xiphoid retraction status information, nasal wing expansion status information, and respiratory sound level information, as well as the indicator image.

4. The auxiliary warning system as described in claim 2 or 3 further includes a storage device electrically connected to the processing device, used to store the information on chest movement status, intercostal retraction status, xiphoid retraction status, nasal ala expansion status, and respiratory sound intensity, as well as the scores obtained by the processing device after judging the information on chest movement status, intercostal retraction status, xiphoid retraction status, nasal ala expansion status, and respiratory sound intensity according to the first respiratory information standard, the second respiratory information standard, the third respiratory information standard, the fourth respiratory information standard, and the fifth respiratory information standard, and adding a timestamp to integrate them into newborn observation information for storage.

5. The auxiliary warning system as described in claim 4 further includes a standard update module, which is electrically connected to the feature standard database and the storage device. The standard update module automatically updates the first respiratory information standard, the second respiratory information standard, the third respiratory information standard, the fourth respiratory information standard and the fifth respiratory information standard by training the newborn observation information through AI learning technology.
