Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of neonatal intensive care, and particularly relates to a pressure injury monitoring system and method applied to neonatal intensive care. BACKGROUND

[0002] Newborns in the neonatal intensive care unit (NICU) often face the risk of pressure injuries (PI) due to their physiological characteristics and treatment needs. Pressure injuries refer to a pathological state in which local tissues are blocked due to continuous pressure, leading to tissue ischemia, necrosis, and even ulceration. Such injuries not only pose a threat to the physical health of newborns, but also increase the difficulty of care, prolong hospital stays, and even lead to complications such as severe infections. Once PI occurs, it will have adverse effects on the patient, medical staff, and family members. Early identification and prevention of PI are difficult problems that need to be solved by clinical medical staff. 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 pressure injuries in newborns mainly rely on the experience of nursing staff and limited pressure monitoring equipment. However, traditional methods are usually based on visual inspection (such as skin redness or damage), which can only identify already formed injuries and cannot predict and intervene in potential risks in advance. Due to the frequent activities of newborns, the detection point position of the pressure monitoring equipment is prone to shift, affecting the accuracy and continuity of the data. SUMMARY

[0082] In a preferred embodiment, the step of obtaining the condition data of the neonate and determining whether the condition data meets the first preset condition if not, marking it as a target neonate, includes:

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

[0084] S102, obtaining the corresponding condition vector according to the condition data;

[0085] S103, obtaining the condition threshold vector;

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

[0087] If the condition vector exceeds the condition threshold vector, it is determined that the neonate's condition is severe, and it is marked as a target neonate.

[0088] As in the above steps S101 to S104, the condition data of the newborn is collected, covering key indicators such as body temperature, heart rate, respiratory rate, blood oxygen saturation, blood pressure, etc. The multi-dimensional condition data collected is converted into a standardized condition vector, a preset condition threshold vector representing the key criteria for clinically determining the critical state of the newborn, and the size relationship between the condition vector and the condition threshold vector is compared. If it exceeds the threshold, it is determined that the newborn is in a critical state and is marked as a target newborn, avoiding the subjectivity and errors of manual judgment and ensuring the objectivity and repeatability of the judgment results.

[0089] In a preferred embodiment, a detection cycle is constructed, and the pressure distribution data of the key parts of the target newborn in the detection cycle is obtained. The step of obtaining corresponding pressure change information from the pressure distribution data comprises:

[0090] S201, constructing a detection cycle;

[0091] S202, obtaining pressure distribution data of key parts of the target newborn in the detection cycle; the key parts include the occiput and the sacrococcygeal part,

[0092] S203, obtaining corresponding multiple transcutaneous oxygen partial pressure values and multiple transcutaneous carbon dioxide partial pressure values from the pressure distribution data;

[0093] S204, obtaining pressure change information from the multiple transcutaneous oxygen partial pressure values and the multiple transcutaneous carbon dioxide partial pressure values.

[0094] As in the above steps S201 to S204, according to the clinical needs and the characteristics of the newborn's 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 rule of pressure injury and the change of skin microcirculation. The pressure distribution data of the key parts (such as the occiput and the sacrococcygeal part) of the target newborn is obtained using a pressure sensor or a body surface pressure measuring device. The key parts are usually high-risk areas of the newborn 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, representing the pressure values of each detection point. Based on the high-pressure points of the pressure distribution data, multiple transcutaneous oxygen partial pressure values (TcPO2) and carbon dioxide partial pressure values (TcPCO2) in the detection cycle are collected. These data reflect the condition of the key part tissue microcirculation. According to the transcutaneous oxygen partial pressure values 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 , where Y represents the pressure change information, i represents the number of the multiple transcutaneous oxygen partial pressure values and the number of the multiple transcutaneous carbon dioxide partial pressure values, i = 1, 2, 3…n, represents the i-th transcutaneous oxygen partial pressure value, The pressure detection point offset information in the detection period is obtained, and the corresponding detection point offset compensation is obtained according to the pressure detection point offset information.

[0095] In a preferred embodiment, the step of constructing the detection period comprises:

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

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

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

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

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

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

[0102] As described in the above steps S2011 to S2016, the time marked as the target newborn is used as the starting point of the detection, which is usually the time point at which the disease data determines that the target newborn is a high-risk individual, ensuring that the starting point of the detection period is accurate and timely. A duration table is created for dynamically allocating detection duration according to different disease vectors, for example, a newborn with a lighter disease can have a longer detection interval (such as 30 minutes), while a newborn with a more serious disease needs to shorten the detection period (such as 5 minutes). The disease vector is extracted from the disease data of the target newborn to match the preset disease conditions in the duration table. The most matched detection duration is found from the duration table according to the extracted disease vector. The end time is calculated according to the start time and the dynamically allocated detection duration. Then a complete detection period 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 the detection duration, high-risk newborns can obtain more intensive monitoring, while newborns with lighter diseases can extend the detection interval to avoid waste of monitoring resources, and can adapt to changes in the disease of different newborns.

[0103] In a preferred embodiment, the step of obtaining the detection period comprises:

[0104] S301, acquire the pressure detection point position image information in the detection period;

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

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

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

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

[0109] S306, acquire the pressure detection point offset information according to the pressure detection point initial position coordinate and the pressure detection point current position coordinate;

[0110] S307, acquire the offset table, wherein the offset table includes a plurality of pressure detection point offset information and a detection point offset compensation corresponding to each pressure detection point offset information;

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

[0112] In the above steps S301 to S308, the pressure detection point position image of the target newborn key part (such as the occiput and sacrococcygeal part) is acquired by using a pressure detection device (such as a pressure sensor or an image capture device). The initial position image records the position distribution of the pressure detection point at the beginning of the detection period, and the current position image records the latest position distribution of the pressure detection point at the end of the detection period. The two images are integrated and superimposed to form a “pressure detection point position integrated image”. A standard two-dimensional plane rectangular coordinate system is constructed on the integrated image to numerize the position data of the detection point. According to the plane rectangular coordinate system, the initial position coordinate and the current position coordinate of each pressure detection point are marked and extracted in the integrated image. According to the initial position coordinate and the current position coordinate, the offset information of the detection point is calculated. The calculation formula of the pressure detection point offset information is , wherein A represents the pressure detection point offset information, (x1, y1) represents the pressure detection point initial position coordinate, and (x2, y2) represents the pressure detection point current position coordinate. 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 matched with the compensation value to respond to the position change, improve the adaptability, reduce the influence of the error data on the risk assessment, and provide more accurate input for the prediction of pressure injury.

[0113] In a preferred embodiment, the body surface temperature data of the target newborn in the detection period and the corresponding body surface humidity data are acquired, and the step of acquiring the body surface temperature and humidity compensation according to the body surface temperature data and the humidity data comprises:

[0114] S401, acquiring the body surface temperature data of the target newborn in the detection period and the corresponding body surface humidity data;

[0115] S402, acquiring a plurality of body surface temperature values according to the body surface temperature data;

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

[0117] S404, acquiring the temperature and humidity compensation according to the plurality of body surface temperature values and the plurality of body surface humidity values.

[0118] In the steps S401 to S404 as described above, the dedicated temperature and humidity sensor or monitoring device is used to collect the body surface temperature and humidity data of the target newborn in real time in the detection period. These data can be continuous time series or discrete data of multiple sampling points in the period. A plurality of body surface temperature values are extracted from the acquired temperature data, which can correspond to different time points or different key parts (such as the occipital part and the sacrococcygeal part). A plurality of body surface humidity values corresponding to the temperature values are extracted from the humidity data. According to the body surface temperature values and the humidity values, the temperature and humidity compensation value is calculated. The calculation formula of the temperature and humidity compensation is , wherein Z represents the temperature and humidity compensation, j represents the number of the plurality of body surface temperature values and the number of the plurality of body surface humidity values, j = 1, 2, 3…t, represents the jth body surface temperature value, represents the jth body surface humidity value, which reduces the interference of the external environment (such as the target newborn humidity or temperature fluctuation) on the monitoring result, and more accurately reflects the skin state of the newborn.

[0119] In a preferred embodiment, the pressure injury risk index is acquired according to the pressure change information, the detection point offset compensation, and the body surface temperature and humidity compensation, it is judged whether the pressure injury risk index exceeds the second preset condition, if it exceeds, the damage warning information is generated and the alarm information is sent. The step comprises:

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

[0121] S502, acquiring the pressure injury risk threshold;

[0122] S503, judging 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, it is determined that the target neonate has a pressure injury risk, and injury warning information is generated, and an alarm information is issued.

[0124] As in steps S501 to S503 described above, the pressure injury risk index of the neonate is calculated according to the pressure change information, the detection point offset compensation, and the body surface temperature and humidity compensation. The calculation formula of the pressure injury risk index is S=Y*A*Z, wherein 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 the risk index calculated is compared with the threshold according to the disease level or nursing requirement of the target neonate. If the pressure injury risk index exceeds the pressure injury risk threshold, it is determined to be high risk, injury warning information is generated, and an alarm mechanism is triggered. The medical staff is prompted by sound and light alarm, the risk event is automatically recorded, the patient monitoring log is updated, the related medical team is reminded through the information system, the deviation caused by a single data source is avoided, the risk index is ensured to be more scientific and representative, the high risk situation can be quickly identified, and the time interval from problem occurrence to intervention is shortened.

[0125] In a preferred embodiment, the step of nursing the target neonate according to the nursing strategy obtained according to the pressure injury risk index comprises:

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

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

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

[0129] S604, nursing the target neonate according to the nursing strategy.

[0130] As in the above steps S601 to S604, the care table is a pre-defined standardized data table containing multiple pressure injury risk intervals and their corresponding care strategies, for example: low risk interval, light care (such as adjusting body position every 3 hours); medium risk interval, moderate care (such as adjusting body position every 2 hours, monitoring local skin temperature changes), high risk interval, intensive care (such as adjusting body position every 1 hour, strengthening pressure distribution detection and skin protection), the care table can be dynamically updated according to historical data, expert recommendations or target hospital care standards, the pressure injury risk index of the newborn is matched with the risk interval in the care table to obtain the target pressure injury risk interval, and the care strategy corresponding to the target risk interval is directly extracted from the care table, each strategy may include: body position management, i.e. adjusting the body position frequency and specific method; skin protection, i.e. using pressure cushion or humidity protection film; monitoring enhancement, i.e. increasing the frequency of pressure, humidity or body temperature monitoring, nursing record, i.e. recording nursing measures and effects to ensure subsequent tracking, the nursing staff operates according to the generated care strategy, for example, adjusting the body position of the newborn, avoiding that the key parts bear pressure for a long time, taking skin protection measures such as dressing, foam pad, etc., reducing local pressure and friction, increasing the detection frequency, and paying close attention to the skin condition and pressure distribution changes of the target newborn in real time, which eliminates the subjectivity and delay in nursing decision-making, improves the response speed and accuracy, and ensures that each newborn can receive adaptive care measures, which helps to reduce the pressure concentration phenomenon of key parts and reduce the risk of injury from the source.

[0131] Please refer to the accompanying Figure 2 The application also provides a pressure injury monitoring system applied to neonatal intensive care, which is used for the pressure injury monitoring method applied to neonatal intensive care, and comprises:

[0132] A condition judgment module is configured to acquire condition data of the newborn, judge whether the condition data meets a first preset condition, and mark the newborn as a target newborn if the condition data does not meet the first preset condition.

[0133] A pressure change module is configured to construct a detection period, acquire pressure distribution data of key parts of the target newborn in the detection period, and acquire corresponding pressure change information according to the pressure distribution data.

[0134] An offset compensation module is configured to acquire offset information of a pressure detection point in the detection period, and acquire corresponding detection point offset compensation according to the offset information of the pressure detection point.

[0135] A temperature and humidity compensation module is configured to acquire surface temperature data and corresponding surface humidity data of the target newborn in the detection period, and acquire surface temperature and humidity compensation according to the surface temperature data and the humidity data.

[0136] The damage risk module is configured to obtain a pressure damage risk index according to the pressure change information, the detection point offset compensation and the body surface temperature and humidity compensation, determine whether the pressure damage risk index exceeds a second preset condition, and if so, generate damage warning information and issue an alarm;

[0137] The nursing strategy module is configured to obtain a nursing strategy according to the pressure damage risk index, and nurse the target newborn according to the nursing strategy.

[0138] The disease condition judgment module judges whether the disease condition data meets the first preset condition (such as the stability of vital signs or skin integrity indicators), and if the disease condition data exceeds the threshold value, it indicates that the newborn may be in a high-risk state of pressure damage, and is marked as a target newborn. The pressure change module dynamically sets the monitoring duration and frequency according to the severity of the disease condition of the target newborn, obtains the pressure distribution of the occiput and sacrococcygeal part through the sensor, and updates it in real time. In combination with the transcutaneous oxygen partial pressure (TcPO2) and carbon dioxide partial pressure (TcPCO2) changes in multiple detection cycles, a comprehensive index reflecting the pressure change information is generated. The offset compensation module records the coordinate difference between the initial position and the current position of the pressure detection point using imaging technology, calculates the offset, and adds a compensation value to the detection point by looking up a preset offset compensation table according to the detected offset information. The temperature and humidity compensation module records the temperature and humidity of the newborn's body surface in real time through the body surface temperature and humidity sensor, determines the temperature and humidity compensation coefficient in combination with multiple body surface temperature and humidity values, and uses it to correct the influence of the skin environment on pressure damage. The damage risk module integrates the pressure change information, the offset compensation and the temperature and humidity compensation to calculate the pressure damage risk index. If the risk index exceeds the preset threshold value, a damage warning information is generated and an alarm is issued. The nursing strategy module matches the risk interval in the nursing table according to the pressure damage risk index, extracts the corresponding nursing strategy (such as body position adjustment, skin protection, etc.), and sends the generated nursing strategy instruction to the nursing equipment or nursing personnel, thereby significantly reducing the occurrence of pressure damage in newborns and improving the nursing effect.
