Description

Technical Field

[0001] The present invention belongs to the technical field of neonatal intensive care monitoring, and in particular relates to a PI monitoring system and method applied to neonatal intensive care monitoring. Background Art

[0002] Due to their physiological characteristics and treatment needs, children in the neonatal intensive care unit (NICU) are often at risk of pressure injury (PI). Pressure injury refers to a pathological state in which local tissues are subjected to continuous pressure, resulting in obstruction of blood circulation, which in turn causes tissue ischemia, necrosis, and even ulcers. This injury not only threatens the physical health of newborns, but may also increase the difficulty of care, prolong hospitalization, and even lead to complications such as serious infections. Once PI occurs, it will have adverse effects on children, medical staff, and family members. Early identification and prevention of the occurrence of PI is a difficult problem that clinical medical staff urgently need to solve. As we all know, the occurrence of PI is a gradual process and is closely related to local tissue ischemia and hypoxia.

[0003] Currently, the prevention and management of neonatal pressure injuries mainly rely on the experience of nursing staff and limited pressure monitoring equipment. However, traditional methods are usually based on appearance inspection (such as redness or damage to the skin), which can only identify existing injuries, but cannot predict and intervene in potential risks in advance.

[0070] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0071] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0072] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0073] Secondly, the present invention is described in detail in conjunction with schematic diagrams. When describing the embodiments of the present invention in detail, for the convenience of explanation, the schematic diagrams are only examples and should not limit the scope of protection of the present invention.

[0074] Please see attached Figure 1 As shown, a PI monitoring method for neonatal intensive care monitoring is provided, comprising:

[0075] S1. Obtain the condition data of the newborn and determine whether the condition data meets the first preset condition. If not, mark the newborn as a target newborn;

[0076] S2. Construct a detection cycle, obtain pressure distribution data of key parts of the target newborn within the detection cycle, and obtain corresponding pressure change information according to the pressure distribution data;

[0077] S3, obtaining the pressure detection point offset information within the detection period, and obtaining the corresponding detection point offset compensation according to the pressure detection point offset information;

[0078] S4, obtaining the target newborn's body surface temperature data and the corresponding body surface humidity data within the detection period, and obtaining body surface temperature and humidity compensation according to the body surface temperature data and humidity data;

[0079] S5. Obtaining a pressure injury risk index according to the pressure change information, the detection point offset compensation, and the body surface temperature and humidity compensation, and determining whether the pressure injury risk index exceeds a second preset condition. If so, generating injury warning information and issuing an alarm message;

[0080] S6. Obtain nursing strategies based on the pressure injury risk index and provide nursing care to target newborns according to the nursing strategies.

[0081] As in the above steps S1 to S6, the neonatal condition data is obtained, and according to the first preset condition (such as a specific disease or physical condition), the neonates who may face a higher risk of PI are screened and marked as target neonates. A detection cycle is constructed, and the pressure distribution of key parts (such as the occipital and sacral regions) is monitored to record the pressure change information, and the pressure detection point offset information (such as the detection point offset caused by the neonate's body movement or position change) within the detection cycle of the target neonate is collected, and dynamic compensation is performed to ensure the accuracy and continuity of the monitoring data, and the temperature and humidity data of the target neonate's body surface are obtained, and based on these two key indicators, their effects on the skin barrier function are obtained. The body surface temperature and humidity compensation is used to correct the effects of the external environment or individual differences on risk assessment, and provide a more comprehensive pressure injury prediction model. The pressure change information, offset compensation and body surface temperature and humidity compensation are combined to calculate the pressure injury risk index of the target neonate, and compared with the second preset condition (such as the risk index threshold). If the risk index exceeds the threshold, an injury warning message is generated and an alarm is issued to remind medical staff to take intervention measures. According to the assessment results of the pressure injury risk index, nursing strategies are formulated for target newborns, such as adjusting body position, optimizing pressure distribution, strengthening skin care or using auxiliary equipment. Through scientific nursing intervention, the risk of PI in newborns is reduced. By collecting key physiological data of newborns in real time, the PI risk can be accurately assessed, and an early warning can be issued before the injury occurs to improve monitoring efficiency. The pressure detection point offset compensation and surface temperature and humidity compensation are used to ensure the accuracy and comprehensiveness of the monitoring data. Customized risk assessment and nursing plans are provided for different individual differences of newborns. Combined with multiple key factors such as pressure distribution, offset information, temperature and humidity, a comprehensive PI risk assessment model is constructed to improve the reliability and scientificity of risk prediction, provide timely nursing strategies and optimize intervention plans, effectively reduce the incidence of neonatal PI, and improve medical quality and neonatal health prognosis.

[0082] In a preferred embodiment, the steps of obtaining the condition data of the newborn, determining whether the condition data meets the first preset condition, and if not, marking the newborn as a target newborn include:

[0083] S101, obtaining the condition data of the newborn;

[0084] S102, obtaining a corresponding disease state vector according to the disease state data;

[0085] S103, obtaining a disease threshold vector;

[0086] S104, determining whether the disease vector exceeds the disease threshold vector;

[0087] If the condition vector exceeds the condition threshold vector, the neonate is judged to be seriously ill and is marked as a target neonate.

[0088] As in the above steps S101 to S104, the newborn's medical data is collected, covering key indicators such as body temperature, heart rate, respiratory rate, blood oxygen saturation, blood pressure, etc. The collected multi-dimensional medical data is converted into a standardized medical condition vector, and a medical condition threshold vector is preset, which represents the key standard for clinically determining the critical condition of the newborn. The size relationship between the medical condition vector and the medical condition threshold vector is compared. If the threshold is exceeded, the newborn is determined to be in a critical condition and is marked as a target newborn, thereby avoiding the subjectivity and error of manual judgment and ensuring the objectivity and repeatability of the judgment result.

[0089] In a preferred embodiment, the steps of constructing a detection cycle, obtaining pressure distribution data of key parts of a target neonate during the detection cycle, and obtaining corresponding pressure change information according to the pressure distribution data include:

[0090] S201, constructing a detection cycle;

[0091] S202, obtaining pressure distribution data of key parts of the target newborn during the detection period; the key parts include the occipital region and the sacral region,

[0092] S203, acquiring corresponding multiple transcutaneous oxygen partial pressure values ​​and multiple transcutaneous carbon dioxide partial pressure values ​​according to the pressure distribution data;

[0093] S204: Obtain pressure change information according to a plurality of transcutaneous oxygen partial pressure values ​​and a plurality of transcutaneous carbon dioxide partial pressure values.

[0094] As in the above steps S201 to S204, according to clinical needs and characteristics of the neonatal condition, a suitable detection cycle is set. For example, 5 minutes or 10 minutes can be selected as a detection cycle according to the occurrence law of pressure injury and changes in skin microcirculation. A pressure sensor or a body surface pressure measurement device is used to obtain pressure distribution data of key parts of the target neonate (such as the occipital region and sacral coccyx). The key parts are usually high-risk areas for neonates due to long-term bed rest or contact with the bed surface. The pressure distribution data is stored in the form of a two-dimensional matrix or grid data to represent the pressure value of each detection point. Based on the high-pressure point of the pressure distribution data, multiple transcutaneous oxygen partial pressure values ​​(TcPO 2 ) and partial pressure of carbon dioxide (TcPCO 2 ), these data reflect the microcirculation status of key tissues. According to the transcutaneous oxygen partial pressure and carbon dioxide partial pressure values ​​at multiple time points, the dynamic pressure change information is calculated. The calculation formula of the pressure change information is: Wherein, Y represents the pressure change information, i represents the number of multiple transcutaneous oxygen partial pressure values ​​and the number of multiple transcutaneous carbon dioxide partial pressure values, i = 1, 2, 3 ... n, T i Expressed as the i-th transcutaneous oxygen partial pressure value, C iIt is expressed as the i-th transcutaneous carbon dioxide partial pressure value. Through dynamic analysis of multiple data points within the detection cycle, the potential risks of pressure changes to tissue health can be captured in time, providing support for early intervention. Only high-risk areas such as the occipital and sacral regions are monitored, reducing unnecessary data collection and optimizing monitoring resource allocation.

[0095] In a preferred embodiment, the step of constructing a detection cycle includes:

[0096] S2011, obtaining the time marked as the target newborn, and marking it as the start time;

[0097] S2012, obtaining a duration table, wherein the duration table includes a plurality of disease vectors and a detection duration corresponding to each disease vector;

[0098] S2013, obtaining a corresponding disease state vector according to the disease state data;

[0099] S2014, obtaining the detection duration from the duration table according to the disease vector;

[0100] S2015, obtaining the end time according to the start time and the detection duration;

[0101] S2016. Obtain a detection period according to the start time and the end time.

[0102] As in the above steps S2011 to S2016, the time marked as the target newborn is used as the starting point of the test. This time is usually the time point when the disease data determines that the target newborn is a high-risk individual, ensuring that the starting point of the test cycle is accurate and timely, and creating a duration table for dynamically allocating test durations according to different disease vectors. For example, a longer test interval (such as 30 minutes) can be set for newborns with milder conditions, while those with more severe conditions need to shorten the test cycle (such as 5 minutes). The disease vector is extracted from the disease data of the target newborn to match the preset disease condition in the duration table. According to the extracted disease vector, the most matching test duration is found in the duration table, and the end time is calculated according to the start time and the dynamically allocated test duration. Subsequently, a complete test cycle is constructed to ensure that the monitoring task is completed within a reasonable time range, providing a clear time frame for subsequent pressure data collection and risk assessment. By dynamically allocating test durations, high-risk newborns can receive more intensive monitoring, while those with milder conditions can extend the test interval to avoid wasting monitoring resources and adapt to changes in the conditions of different newborns.

[0103] In a preferred embodiment, the step of obtaining the pressure detection point offset information within the detection period and obtaining the corresponding detection point offset compensation according to the pressure detection point offset information includes:

[0104] S301, obtaining image information of the pressure detection point position within the detection cycle;

[0105] S302, acquiring the corresponding initial position image of the pressure detection point and the current position image of the pressure detection point according to the position image information of the pressure detection point;

[0106] S303, integrating the pressure detection point initial position image and the pressure detection point current position image to obtain a pressure detection point position integrated image;

[0107] S304, constructing a plane rectangular coordinate system in the integrated image of the pressure detection point position;

[0108] S305, obtaining the initial position coordinates of the pressure detection point and the current position coordinates of the pressure detection point in the pressure detection point position integrated image according to the plane rectangular coordinates;

[0109] S306, obtaining pressure detection point offset information according to the initial position coordinates of the pressure detection point and the current position coordinates of the pressure detection point;

[0110] S307, obtaining an offset table, wherein the offset table includes offset information of multiple pressure detection points and a monitoring point offset compensation corresponding to each pressure detection point offset information;

[0111] S308. Obtain corresponding detection point offset compensation from the offset table according to the pressure detection point offset information.

[0112] As in the above steps S301 to S308, a pressure detection device (such as a pressure sensor or an image capture device) is used to obtain a pressure detection point position image of a key part of the target newborn (such as the occipital region and the sacral region), the initial position image records the position distribution of the pressure detection point at the beginning of the detection cycle, and the current position image records the latest position distribution of the pressure detection point at the end of the detection cycle. The two images are integrated and superimposed to form a "pressure detection point position integrated image", and a standard two-dimensional plane rectangular coordinate system is constructed on the integrated image to digitize the position data of the detection point. According to the plane rectangular coordinate system, the initial position coordinates and current position coordinates of each pressure detection point are marked and extracted in the integrated image, and the offset information of the detection point is calculated according to the initial position coordinates and the current position coordinates. The calculation formula of the pressure detection point offset information is: Where A represents the pressure detection point offset information, (x 1 ,y 1 ) represents the initial position coordinates of the pressure detection point, (x 2 ,y 2) is represented by the current position coordinates of the pressure detection point. Through the offset table, the calculated offset information is matched with the preset offset range in the table to obtain the corresponding compensation value. The offset information is dynamically calculated and the compensation value is matched to respond to position changes, improve adaptability, reduce the impact of erroneous data on risk assessment, and provide more accurate input for the prediction of pressure injuries.

[0113] In a preferred embodiment, the steps of obtaining the target neonatal body surface temperature data and the corresponding body surface humidity data within the detection period, and obtaining the body surface temperature and humidity compensation according to the body surface temperature data and the humidity data include:

[0114] S401, obtaining the target newborn's body surface temperature data and the corresponding body surface humidity data within the detection period;

[0115] S402, acquiring corresponding multiple body surface temperature values ​​according to the body surface temperature data;

[0116] S403, acquiring a plurality of body surface humidity values ​​corresponding to a plurality of body surface temperature values ​​according to the body surface humidity data;

[0117] S404: Obtain temperature and humidity compensation according to a plurality of body surface temperature values ​​and a plurality of body surface humidity values.

[0118] As in the above steps S401 to S404, a dedicated temperature and humidity sensor or monitoring device is used to collect the target newborn's surface temperature and humidity data in real time during the detection period. These data can be a time series collected continuously or discrete data at multiple sampling points within the period. Multiple surface temperature values ​​are extracted from the acquired temperature data. These temperature values ​​may correspond to different time points or different key parts (such as the occipital region and the sacral coccyx). Multiple surface humidity values ​​corresponding to the temperature values ​​are extracted from the humidity data. The temperature and humidity compensation values ​​are calculated based on the surface temperature and humidity values. The calculation formula for temperature and humidity compensation is: Where Z represents temperature and humidity compensation, j represents the number of multiple body surface temperature values ​​and multiple body surface humidity values, j = 1, 2, 3…t, W j Expressed as the jth body surface temperature, S j It is expressed as the jth body surface humidity value, which reduces the interference of the external environment (such as humidity or temperature fluctuations of the target newborn) on the monitoring results and more accurately reflects the skin condition of the newborn.

[0119] In a preferred embodiment, the steps of obtaining a pressure injury risk index according to pressure change information, detection point offset compensation, and body surface temperature and humidity compensation, determining whether the pressure injury risk index exceeds a second preset condition, and if so, generating injury warning information and issuing an alarm information include:

[0120] S501, obtaining a pressure injury risk index according to pressure change information, detection point offset compensation, and body surface temperature and humidity compensation;

[0121] S502, obtaining a pressure injury risk threshold;

[0122] S503, determining whether the pressure injury risk index exceeds the pressure injury risk threshold;

[0123] If the pressure injury risk index exceeds the pressure injury risk threshold, the target newborn is judged to be at risk of pressure injury, and injury warning information is generated and an alarm is issued.

[0124] As in the above steps S501 to S503, the neonatal pressure injury risk index is calculated based on the pressure change information, detection point offset compensation and body surface temperature and humidity compensation. The calculation formula of the pressure injury risk index is S=Y*A*Z, where S represents the pressure injury risk index, Y represents the pressure change information, A represents the pressure detection point offset information, and Z represents the temperature and humidity compensation. One or more risk thresholds are preset and automatically adjusted according to the target neonatal condition level or nursing requirements. The calculated risk index is compared with the threshold. If the pressure injury risk index exceeds the pressure injury risk threshold, it is judged to be high risk, and injury warning information is generated, and the alarm mechanism is triggered. The sound and light alarm prompts the medical staff, the risk event is automatically recorded, the patient monitoring log is updated, and reminders are sent to the relevant medical team through the information system to avoid deviations caused by a single data source, ensure that the risk index is more scientific and representative, and can quickly identify high-risk situations and shorten the time interval from the occurrence of the problem to intervention.

[0125] In a preferred embodiment, the steps of obtaining a nursing strategy according to the pressure injury risk index and caring for the target newborn according to the nursing strategy include:

[0126] S601, obtaining a nursing table, wherein the nursing table includes a plurality of pressure injury risk intervals and a nursing strategy corresponding to each pressure injury risk interval;

[0127] S602, obtaining a target pressure injury risk interval according to the pressure injury risk index;

[0128] S603, obtaining corresponding nursing strategies from the nursing table according to the target pressure injury risk interval;

[0129] S604. Care for the target newborn according to the nursing strategy.

[0130] As in the above steps S601 to S604, the nursing table is a predefined standardized data table, which includes multiple pressure injury risk intervals and their corresponding nursing strategies, for example: low risk interval, mild nursing (such as adjusting the body position every 3 hours); medium risk interval, moderate nursing (such as adjusting the body position every 2 hours and monitoring local skin temperature changes); high risk interval, severe nursing (such as adjusting the body position every 1 hour, strengthening pressure distribution detection and skin protection). The nursing table can be dynamically updated according to historical data, expert advice or target hospital nursing standards, and the pressure injury risk index of the newborn is matched with the risk interval in the nursing table to obtain the target pressure injury risk interval. The nursing strategy corresponding to the target risk interval is directly extracted from the nursing table. Each strategy may include : Body position management, that is, adjusting the frequency and specific methods of body position; skin protection, that is, using pressure cushions or humidity protection films; enhanced monitoring, that is, increasing the frequency of pressure, humidity or temperature monitoring; nursing records, that is, recording nursing measures and effects to ensure follow-up tracking. Nursing staff operate according to the generated nursing strategies, for example, adjusting the body position of the newborn to avoid prolonged pressure on key parts, taking skin protection measures such as dressings, foam pads, etc. to reduce local pressure and friction, increasing the frequency of testing, and paying real-time attention to the skin condition and pressure distribution changes of the target newborns, eliminating subjectivity and delays in nursing decisions, improving response speed and accuracy, ensuring that each newborn can receive appropriate nursing measures, and helping to reduce the concentration of pressure in key parts and reduce the risk of injury from the source.

[0134] An offset compensation module is used to obtain the offset information of the pressure detection point within the detection cycle, and obtain the corresponding detection point offset compensation according to the pressure detection point offset information;

[0135] The temperature and humidity compensation module is used to obtain the target newborn's body surface temperature data and the corresponding body surface humidity data during the detection period, and obtain the body surface temperature and humidity compensation according to the body surface temperature data and humidity data;

[0136] An injury risk module is used to obtain a pressure injury risk index based on pressure change information, detection point offset compensation, and body surface temperature and humidity compensation, and to determine whether the pressure injury risk index exceeds a second preset condition. If so, an injury warning information is generated and an alarm is issued;

[0137] The nursing strategy module is used to obtain nursing strategies according to the pressure injury risk index and to provide nursing care to target newborns according to the nursing strategies.

[0138] As mentioned above, the condition judgment module determines whether the first preset condition (such as the stability of vital signs or skin integrity index) is met by collecting the condition data. If the condition data exceeds the threshold, it indicates that the newborn may be at high risk of pressure injury and is marked as a target newborn. The pressure change module dynamically sets the monitoring time and frequency according to the severity of the condition of the target newborn, obtains the pressure distribution of the occipital and sacral regions through sensors, and updates it in real time, combining the transcutaneous oxygen partial pressure (TcPO 2 ) and partial pressure of carbon dioxide (TcPCO 2 ) changes, and generate a comprehensive indicator reflecting the pressure change information. The offset compensation module uses imaging technology to record the coordinate difference between the initial position and the current position of the pressure detection point, calculates the offset, and adds a compensation value to the detection point according to the detected offset information by looking up the preset offset compensation table. The temperature and humidity compensation module records the surface temperature and humidity of the newborn in real time through the surface temperature and humidity sensor, and combines multiple surface temperature and humidity values ​​to determine the temperature and humidity compensation coefficient, which is used to correct the impact of the skin environment on pressure injuries. The injury risk module combines pressure change information, offset compensation and temperature and humidity compensation to calculate the pressure injury risk index. If the risk index exceeds the preset threshold, it generates injury warning information and issues an alarm. The nursing strategy module matches the risk interval in the nursing table according to the pressure injury risk index, extracts the corresponding nursing strategy (such as position adjustment, skin protection, etc.), and sends the generated nursing strategy instructions to nursing equipment or nursing staff, which significantly reduces the occurrence of pressure injuries in neonates and improves nursing effects.
