Description

Technical Field

[0001] The present invention relates to the technical field of complication monitoring, and particularly to an orthopedic postoperative complication monitoring system and method. Background Art

[0002] After orthopedic surgery, it is necessary to collect the physical activity data of patients in real time, monitor muscle strength, analyze the possible problems in the rehabilitation process, help doctors adjust the rehabilitation plan in time, improve the rehabilitation effect and quality of life of orthopedic postoperative patients. The system aims to make the rehabilitation process more scientific and efficient, reduce the uncertain risks in the rehabilitation process, and enhance the confidence and cooperation of patients in rehabilitation treatment. Orthopedic rehabilitation treatment requires continuous observation of bone growth and healing.

[0003] After retrieval, the publication (announcement) number: CN119049701A discloses a risk assessment and supervision system during large bone flap decompression surgery, including a large bone flap decompression surgery patient database, an intracranial pressure detection device, a cerebrospinal fluid drainage device, and a multivariable combined model. The multivariable combined model includes an index input module, an intraoperative risk assessment and complication prediction module, a postoperative intracranial pressure monitoring and warning module, and a cerebrospinal fluid drainage and management module; through the multivariable combined model, intraoperative risk assessment and complication prediction of patients can be carried out, the intracranial pressure of patients can be monitored and managed, and the intracranial pressure of patients can be reduced through the cerebrospinal fluid drainage device. Therefore, the present invention can greatly improve the risk assessment level of patients during large bone flap decompression surgery and effectively supervise the postoperative conditions of patients.

[0004] Although the above solution greatly improves the risk assessment level of patients during large bone flap decompression surgery and can effectively supervise the postoperative conditions of patients, the sample of the detected data is small and the detection time span is small, resulting in easy misjudgment in detection, causing unnecessary trouble, and patients need to change the rehabilitation treatment plan in a timely manner. Summary of the Invention

[0005] The main purpose of the present invention is to provide an orthopedic postoperative complication monitoring system and method to solve the problems that the sample of the detected data is small, the detection time span is small, resulting in easy misjudgment in detection, causing unnecessary trouble, and patients need to change the rehabilitation treatment plan in a timely manner.

[0006] To achieve the above object, the present invention provides the following technical solutions: An orthopedic postoperative complication monitoring system, the system includes a data storage module, a rehabilitation progress module, a serum detection module, a reexamination module, and a rehabilitation result module; The data storage module specifically stores whether there is an implant in the patient's surgery, records the material and source of the implant, also records the patient's age, height, weight and relevant medical history, collects the cognitive status evaluated by the MMSE scale, the depressive status evaluated by the GDS scale, monitors SaO2, invasive arterial blood pressure and bispectral index value before surgery, and simultaneously records rScO2, MAP at rest before surgery and rScO2, MAP values under pure oxygen inhalation; The rehabilitation progress module is specifically a motion sensor that monitors the patient's motion state, decomposes the motion state into a standard state and an error state, considers the modeling error, calculates the attitude update equation to reflect the actual attitude change, and compares it with the updated standard state to perform real-time estimation and correction of the error state and adjust the rehabilitation treatment plan; The serum detection module includes an automatic biochemical analyzer for detecting the patient's serum. First, 3 ml of fasting venous blood of the patient is taken on the day before surgery, and on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery. It is centrifuged at 3500 r / min for 10 min at low temperature and stored at -18°C. The automatic biochemical analyzer is used to detect the serum CRP level by immunoturbidimetry, detect the ALB level by enzyme-linked immunosorbent assay, and calculate the ratio of CRP / ALB at different times. If the CRP / ALB ratio exceeds the threshold, it is considered an infection; The re-examination module is used to detect the patient's blood. 3 ml of fasting venous blood of the patient is taken, and the blood of the patient is taken on the day before surgery and on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery. Subsequently, the WBC is measured by flow cytometry, the ESR is quantitatively detected by the Westergren tube method, the hsCRP is quantitatively detected by latex-enhanced rate nephelometry, and the PCT is detected by chemiluminescence immunoassay; The rehabilitation result module calls the patient's personal data in the data storage module, and calls the detection results of serum and blood from the serum detection module and the re-examination module on the day before surgery and on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery respectively. Compare the detection results with the normal values. If normal, call the motion state data of the patient in the rehabilitation progress module and adjust the rehabilitation treatment plan. If abnormal, give a warning and conduct more detailed detection and treatment on the patient subsequently.

[0007] Preferably, the implants in the patient's surgery include intramedullary nails, plates, screws and artificial joints. The process of implanting the implant into the human body will bring in pathogens such as Staphylococcus aureus in the air, on the operator or the patient's body surface. After the patient's surgery, transient bacteremia caused by pathogens will occur due to common skin and soft tissue, oropharyngeal or urogenital tract infections. By recording the material and source of the implant in the village storage, it is convenient to track the source of infection subsequently and ensure the sterilization and asepticity of the implant.

[0008] Preferably, the motion sensor is used to detect the gravitational acceleration of the patient in all directions, monitor the gravitational acceleration vector under standard conditions, calculate the error vector of the gravitational acceleration, so as to understand the subtle changes and improvement conditions of the patient during the rehabilitation process, and provide a basis for the adjustment and optimization of the rehabilitation treatment plan.

[0009] Preferably, both CRP and ALB detected in the serum detection module are synthesized by the liver. CRP will increase rapidly due to the activation of inflammatory factors in the early stage of body infection, accelerating the organ damage of infected patients; ALB plays an important role in maintaining the body's acid-base balance and protecting the function of organ tissues. When orthopedic surgery patients are infected, the serum CRP level and the CRP / ALB ratio increase significantly beyond the normal value threshold, and the serum ALB level decreases significantly.

[0010] Preferably, the normal value of WBC determination in the re-examination module using flow cytometry is: (4~10)×10 9 / L; the normal value of quantitative detection of ESR by Westergren tube determination method: <15 mm / h for men and <20 mm / h for women; the normal value of quantitative detection of hsCRP by latex enhanced rate nephelometry: 0~3 mg / L; the normal value of PCT detected by immunochemiluminescence method: <0.5 ng / ml.

[0011] Preferably, when the detection is carried out in the re-examination module, it is a common phenomenon that the WBC value on the first day after surgery is higher than the normal value on the 1st, 2nd, 3rd, and 4th days after surgery, and it drops to the range of the day before surgery from the 5th to the 7th day after surgery; the ESR value increases successively from the 1st, 2nd, 3rd, 4th, and 5th days after surgery, and the values on the 6th and 7th days after surgery begin to decrease. The values of hsCRP on the 1st and 2nd days after surgery are higher than the normal value, and are lower than the normal value on the 3rd, 5th, 6th, and 7th days after surgery. The values of PCT on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery are all within the normal value range.

[0012] Preferably, the rehabilitation structure module calls the personal data of each patient for targeted comparison, and at the same time calls the motion state of the patient in the rehabilitation progress module, adjusts the rehabilitation treatment plan in a timely manner, and transmits the information to the attending doctor for convenient storage and treatment.

[0013] A method for using an orthopedic postoperative complication monitoring system: The method includes the following steps; Step 1: Input the personal data of the patient into the data storage module, and draw 6 ml of fasting venous blood from the patient 1 day before surgery, divide it into two portions of 3 ml each. One portion is centrifuged and the serum is sent to an automatic biochemical analyzer for detection and calculation of the CRP / ALB ratio, and the other portion is sent to the re-examination module for detection using flow cytometry, Westergren tube determination method, latex enhanced rate nephelometry, and immunochemiluminescence method respectively; Step 2: Take 6 ml of fasting venous blood from the patient on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery, divide it into two portions of 3 ml each, and repeat the detection steps in Step 1; Step 3: Call the personal data of the patient in the data storage module, and call the detection results of serum and blood from the serum detection module and the re-examination module on the day before surgery, and on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery respectively. Compare the detection results with the normal values. If normal, call the motion state data of the patient in the rehabilitation progress module; if abnormal, give a warning Compared with the prior art, the present invention has the following beneficial effects: First, in the present invention, through the setting of the serum detection module, both CRP and ALB are synthesized by the liver. CRP will rise rapidly due to the activation of inflammatory factors in the early stage of body infection, accelerating the organ damage of infected patients; ALB plays an important role in maintaining the body's acid-base balance and protecting the function of organ tissues. Both have positive significance in the evaluation of the prognosis of critically ill patients and have diagnostic value for postoperative infections in orthopedic surgery patients. When orthopedic surgery patients have an infection, the serum CRP level, CRP / ALB ratio increase significantly, and the serum ALB level decreases significantly. Moreover, CRP, ALB, and CRP / ALB ratio can all be used as diagnostic indicators for postoperative infections in orthopedic patients. Therefore, clinically, close attention should be paid to the serum CRP and ALB levels of orthopedic patients after surgery. Once abnormal changes occur, symptomatic treatment should be carried out in a timely manner to improve the patient's prognosis.

[0014] Second, in the present invention, through the setting of the re-examination module, there are certain rules for the changes in the concentrations of blood WBC, ESR, hsCRP, and PCT after orthopedic implants. In the absence of infection, the concentrations of blood WBC, ESR, and hsCRP increase to the peak and then decrease at different time points, while the PCT value has no obvious change; the combined detection of the dynamic changes of these 4 indicators in the early stage after orthopedic implants has good clinical application value for the evaluation of the occurrence of early postoperative incision infections. The sample time span of the detection data is large, and the types of detection data are diverse, improving the accuracy of judgment.

[0015] Third, in the present invention, through the setting of the rehabilitation result module, the motion sensor is used to detect the gravitational acceleration of the patient in all directions in real time, and can collect data on the motion angle, angular velocity, and acceleration of the patient's limbs to understand the range and motion mode of rehabilitation exercises; at the same time, it can also collect plantar pressure data for evaluating the force-bearing situation; collect physiological data, including heart rate and respiration, to reflect the patient's physical state, comprehensively evaluate the patient's physical condition, and timely adjust the patient's rehabilitation treatment plan, accelerating the patient's rehabilitation speed.

[0016] Figure 1 is the flowchart of the present invention; Figure 2 This is the flowchart of blood treatment in the present invention. Specific embodiments

[0017] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. Embodiment

[0018] As Figure 1 、 Figure 2 shown, an orthopedic postoperative complication monitoring system includes a data storage module, a rehabilitation progress module, a serum detection module, a re-examination module and a rehabilitation result module; The data storage module specifically stores whether there are implants in the patient's surgery, records the material and source of the implants, also records the patient's age, height, weight and relevant medical history, collects the cognitive status evaluated by the MMSE scale, the depression status evaluated by the GDS scale, preoperatively monitors SaO2, invasive arterial blood pressure and bispectral index value, and simultaneously records the rScO2, MAP values at rest before surgery and the rScO2, MAP values under pure oxygen inhalation; The rehabilitation progress module is specifically a motion sensor that monitors the patient's motion state, decomposes the motion state into a standard state and an error state, considers the modeling error, calculates the attitude update equation to reflect the actual attitude change, compares it with the updated standard state, and performs real-time estimation and correction on the error state to adjust the rehabilitation treatment plan; The serum detection module includes an automatic biochemical analyzer for detecting the patient's serum. First, 3 ml of fasting venous blood of the patient is taken on the day before surgery, the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery, centrifuged at 3500 r / min for 10 min at low temperature, and stored at -18°C. The automatic biochemical analyzer is used to detect the serum CRP level by immunoturbidimetry, detect the ALB level by enzyme-linked immunosorbent assay, and calculate the ratio of CRP / ALB at different times. If the CRP / ALB ratio exceeds the threshold, it is considered an infection; The re-examination module is used to detect the patient's blood. 3 ml of fasting venous blood of the patient is taken, and the blood of the patient is taken on the day before surgery, the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery. Subsequently, the WBC is measured by flow cytometry, the ESR is quantitatively detected by the Westergren tube method, the hsCRP is quantitatively detected by latex-enhanced rate nephelometry, and the PCT is detected by immunochemiluminescence; The rehabilitation result module calls the personal data of the patient in the data storage module, and calls the test results of serum and blood from the serum test module and the re-examination module on the 1st day before surgery, and the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery respectively. Compare the test results with the normal values. If normal, call the motion state data of the patient in the rehabilitation progress module and adjust the rehabilitation treatment plan. If abnormal, give a warning and conduct more detailed tests and treatments on the patient subsequently.

[0019] The implants in the patient's surgery include intramedullary nails, plates, screws, and artificial joints. The process of implanting the implants into the human body will bring in pathogens such as staphylococcus in the air, on the operator or the patient's body surface. After the patient's surgery, transient bacteremia caused by pathogens will occur due to common skin and soft tissue, oropharyngeal, or urogenital tract infections. By recording the material and source of the implants in the storage, it is convenient to track the source of infection subsequently and ensure the sterilization and asepsis of the implants.

[0020] The motion sensor is used to detect the gravitational acceleration of the patient in all directions, monitor the gravitational acceleration vector under standard conditions, and calculate the error vector of the gravitational acceleration, so as to understand the subtle changes and improvement conditions of the patient during the rehabilitation process, and provide a basis for the adjustment and optimization of the rehabilitation treatment plan.

[0021] At the same time, the motion sensor is used to detect the gravitational acceleration of the patient in all directions in real time, and can collect data on the motion angle, angular velocity, and acceleration of the patient's limbs to understand the range and motion mode of the rehabilitation exercise; at the same time, it can also collect plantar pressure data to evaluate the force condition; collect physiological data, including heart rate and respiration, to reflect the patient's physical state, comprehensively evaluate the patient's physical condition, and adjust the patient's rehabilitation treatment plan in a timely manner, which speeds up the patient's rehabilitation speed; Both CRP and ALB detected in the serum test module are synthesized by the liver. CRP will rise rapidly due to the activation of inflammatory factors in the early stage of body infection, accelerating organ damage in infected patients; ALB plays an important role in maintaining the body's acid-base balance and protecting organ tissue functions. When orthopedic surgery patients are infected, the serum CRP level and the CRP / ALB ratio increase significantly beyond the normal value threshold, and the serum ALB level decreases significantly.

[0022] The normal values for the determination of WBC in the re-examination module using flow cytometry are: (4~10)×109 / L; the normal values for the quantitative detection of ESR by the Westergren tube method are: <15 mm / h for men and <20 mm / h for women; the normal values for the quantitative detection of hsCRP by latex-enhanced rate nephelometry are: 0~3 mg / L; the normal values for the detection of PCT by immunochemiluminescence method are: <0.5 ng / ml.

[0023] In the case of no incision infection after orthopedic implants, the blood white blood cells (WBC) are still elevated. The WBC count in the blood routine is increased on the first day after surgery and exceeds the normal value. It starts to decline to the normal range from the second day after surgery. The reason is considered that after surgery, due to the body being in a state of emergency, the number of blood WBC in the body increases acutely. As time goes by, the body's emergency response weakens, and the number of blood WBC in the body also begins to decrease. It can be seen that the increase in blood routine WBC after surgery cannot be used as a single standard for the presence of incision infection.

[0024] ESR reflects the association between the aggregation of fibrinogen and immunoglobulins in the blood and the rate of decline of red blood cells. The change of ESR is affected by various factors. For example, it shows an increased rate during the active stage of tuberculosis, rheumatoid arthritis, after trauma surgery, and acute stress response. The positive rate of ESR in predicting infection is low, so the effect of detecting and judging infection alone is not good, but it is helpful in excluding infection in the case of negative results.

[0025] HsCRP is one of the acute-phase response proteins. Factors such as surgery, infection, and trauma stress stimuli can all cause hsCRP to increase. If hsCRP continues to increase after surgery or rises again after a decline, deviating from the normal change pattern, it indicates that the patient may have postoperative incision infection or the original inflammation persists.

[0026] Procalcitonin (PCT) is the precursor form of calcitonin. It will increase significantly when the body is stimulated by bacteria, such as in the case of bacteremia. Once the PCT content increases, it indicates that there is already an infection. In the absence of infection, the PCT concentration will not exceed the normal value. Once it increases and is greater than the normal value, it is necessary to consider the possible presence of bacterial infection.

[0027] In summary, there are certain rules in the changes of blood WBC, ESR, hsCRP, and PCT concentrations after orthopedic implants. In the absence of infection, the concentrations of blood WBC, ESR, and hsCRP increase to the peak value at different time points and then decline, while the PCT value has no obvious change. The combined detection of these four indicators for the dynamic changes in the early stage after orthopedic implants has good clinical application value for the assessment of the occurrence of early postoperative incision infection. The sample time span of the detection data is large, and the types of detection data are diverse, which improves the accuracy of judgment.

[0028] When the detection is carried out in the re-inspection module, it is a common phenomenon that the WBC value on the first day after surgery is higher than the normal value on the 1st, 2nd, 3rd, and 4th days after surgery, and it drops to the range of the day before surgery from the 5th day to the 7th day after surgery; the ESR value increases successively from the 1st, 2nd, 3rd, 4th, and 5th days after surgery, and the values on the 6th and 7th days after surgery begin to decrease. The hsCRP value is higher than the normal value on the 1st and 2nd days after surgery and lower than the normal value on the 3rd, 5th, 6th, and 7th days after surgery. The PCT value is within the normal range on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after surgery.

[0029] The rehabilitation structure module calls the personal data of each patient to conduct targeted comparisons. At the same time, it calls the motion state of the patient in the rehabilitation progress module, adjusts the rehabilitation treatment plan in a timely manner, and transmits the information to the attending doctor for convenient storage and treatment.

[0030] A method for using an orthopedic postoperative complication monitoring system: The method includes the following steps; Step 1: Input the personal data of the patient into the data storage module. And 6 ml of the patient's fasting venous blood is drawn 1 day before the operation and divided into two portions of 3 ml each. One portion of the centrifuged serum is sent to an automatic biochemical analyzer for detection and calculation of the CRP / ALB ratio, and the other portion is sent to the recheck module for detection using flow cytometry, Westergren tube assay, latex enhanced rate nephelometry, and immunochemiluminescence assay respectively; Step 2: Take 6 ml of the patient's fasting venous blood on the 1st, 2nd, 3rd, 5th, 6th, and 7th days after the operation and divide it into two portions of 3 ml each, and repeat the detection steps in Step 1; Step 3: Call the personal data of the patient in the data storage module, and call the detection results of the serum and blood from the serum detection module and the recheck module respectively on the 1st day before the operation and the 1st, 2nd, 3rd, 5th, 6th, and 7th days after the operation. Compare the detection results with the normal values. If normal, call the motion state data of the patient in the rehabilitation progress module; if abnormal, give a warning.

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
