Description

Technical Field

[0001] The present invention relates to the technical field of medical systems, and in particular to an intelligent handover system for cardiovascular surgery nursing and an implementation method thereof. Background Art

[0002] With the continuous advancement of medical technology, cardiovascular surgery has become increasingly complex and sophisticated, placing higher demands on the quality and efficiency of surgical care. Accurate and timely information transfer, particularly during surgical nursing handovers, has become crucial for ensuring patient safety and treatment outcomes. However, traditional cardiovascular surgical nursing handover methods still have numerous shortcomings and are unable to meet the demands of modern healthcare.

[0003] Currently, most hospitals still use paper documents or simple spreadsheets to record and communicate shift handover information. While this method is simple and intuitive, it often struggles to comprehensively and accurately record and communicate all critical information required for complex cardiovascular surgical care. For example, information such as the patient's detailed medical history, key events during the procedure, and the specific instruments and medications used can be improperly recorded or omitted, leading to inadequate handovers. Furthermore, paper documents are easily lost or damaged, hindering subsequent query and statistical analysis.

[0004] Some hospitals have begun experimenting with electronic systems for nursing handovers, but these systems typically operate independently and struggle to seamlessly integrate with other hospital information systems. This leads to information silos, forcing medical staff to switch between multiple systems, increasing their workload and potentially leading to errors due to information asynchrony. Furthermore, these systems often lack intelligent functionality and are unable to provide advanced decision support, such as risk assessment and resource optimization.

[0005] Another common problem is that existing handover systems often focus on recording and transmitting information, while neglecting to standardize the handover process. This can lead to significant variations in the content and methods of handovers between different medical staff, increasing the risk of medical errors. Especially in the high-pressure environment of cardiovascular surgery, this inconsistency can have serious consequences.

[0006] Furthermore, existing systems generally lack effective support for medical device management. In cardiovascular surgery, the use of precision instruments and specialized equipment is directly related to surgical success. However, many hospitals still rely on manual record-keeping and empirical judgment to manage these critical resources, making it difficult to accurately assess efficiency and optimize allocation.

[0007] In the face of these problems, there is an urgent need for an intelligent cardiovascular surgery nursing handover system that can fully integrate information, intelligent management, and standardized operations. The present invention addresses the above technical issues and proposes an innovative solution. Summary of the Invention

[0008] The core technical problem to be solved by the present invention is how to build an efficient, accurate and intelligent cardiovascular surgery nursing handover system and method to achieve comprehensive information collection, intelligent analysis and precise transmission, while providing advanced decision support functions such as risk assessment and resource optimization.

[0014] The information sending end is used to record the patient's condition after the second patient is taken to the ward and send it to the receiving end;

[0015] The information collection terminal is set up in the cardiovascular operating room and is a doctor's station for obtaining information about the second patient before and after entering the room, equipment information, and medical record information;

[0016] The electronic signature terminal is used to output the electronic signature sheet to the receiving terminal, which displays it and provides signature confirmation;

[0029] The electronic signature sheet includes a signature confirmation module and an image display module;

[0030] The receiving end, the information sending end, the output end, the information collecting end and the electronic signature end further include a camera module.

[0031] The method based on the intelligent handover system for cardiovascular surgery nursing comprises the following steps:

[0032] Step 1: The receiving end inputs the first patient information; the medical staff enters the second patient information into the output end, and the second communication terminal device sends the second patient information to the management end;

[0033] Step 2: The receiving end receives the second patient information sent by the management end and compares it with the first patient information; if the comparison is consistent, the medical staff completes the patient confirmation; if the comparison is inconsistent, return to step 1;

[0034] Step 3: The receiving end displays the electronic signature sheet with the signature and information confirmation, and the medical staff signs and confirms. The second recognition device recognizes the signature information of the medical staff and sends the signature information to the receiving end. The receiving end confirms the signature information of the medical staff; the medical staff pastes the medical staff identity QR code on the medical record of the second patient and transfers the second patient to the intensive care unit;

[0035] Step 4: The first identification device identifies the medical staff identity QR code and sends it to the receiving end. The receiving end compares the received medical staff identity QR code with the second patient identity QR code received locally. If the comparison is consistent, the receiving end completes the patient acceptance confirmation procedure; if the comparison is inconsistent, return to step 1;

[0036] Step 5. The output end collects the information of the second patient, the device information, and the medical record information through the information collection end, completes the information collection of the second patient, confirms the device information, and sends it to the management end; the management end sends the information of the second patient to the receiving end, and the output end collects and sends the information of the second patient after being admitted to the intensive care unit through the information sending end; the receiving end completes the patient acceptance confirmation procedure based on the received information.

[0037] Preferably, before step 1, the method further includes setting key points to be signed in the electronic signature form on the electronic signature terminal of the doctor;

[0038] Before step three, the method also includes the medical staff confirming the first patient information and the second patient information, and the electronic signature end printing the electronic signature sheet. The medical staff signs and confirms the printed electronic signature sheet, and displays the signed electronic signature sheet on the electronic signature end for the second identification device to identify the signature information.

[0039] Preferably, in step 1, the receiving end displays the first patient information, the first patient information is input to the receiving end, the first identification device identifies the first patient information as medical record information, and the receiving end receives it;

[0040] The output end displays a filling interface for the second patient information, the second communication terminal device enters the second patient information, the output end displays and prints a QR code containing the second patient information, the medical staff pastes the printed QR code onto the medical record of the second patient, and the second identification device identifies the QR code.

[0041] Preferably, in step five, the device information at the output end includes whether the device has been cleaned in a cleaning center, whether it needs to be sterilized, and whether it needs to be packaged for use.

[0042] Preferably, in step 1, the second patient information includes surgical method, admission diagnosis, surgeon, operating physician, anesthesiologist, ASA classification and risk factor, surgical time, surgical method, department code, and bed number;

[0043] In step 2, the comparison contents are patient code, name, surgical method, ASA classification and risk factor;

[0047] The vital signs include body temperature, respiratory rate, pulse, blood pressure, and blood oxygen saturation;

[0048] In step five, if any physical abnormality is detected, the output terminal issues an alarm and triggers the intelligent risk assessment module to recalculate the patient's surgical risk index R.

[0049] The beneficial technical effects brought about by the technical solution of the present invention are:

[0050] From an overall architectural perspective, this invention constructs a closed-loop information management system by organically integrating the receiving end, information transmitting end, output end, information collection end, electronic signature end, and management end. This modular design not only ensures smooth information flow but also facilitates system expansion and upgrades. The collaborative work between these modules effectively resolves the issues of information silos and data inconsistencies in traditional systems.

[0051] Regarding information collection and transmission, this invention incorporates QR code technology and an electronic signature system, significantly improving the efficiency and accuracy of information entry and verification. This not only reduces the workload for medical staff but also minimizes the potential for human error. This rapid and accurate information transmission mechanism can significantly enhance patient safety, particularly in the high-pressure environment of cardiovascular surgery.

[0052] A major innovation of this invention lies in the introduction of an intelligent risk assessment module. By comprehensively considering multiple factors, including the patient's physical condition, surgical difficulty, and the complexity of comorbidities, the system can provide objective and quantitative risk assessment results. This provides strong decision-making support for doctors in formulating surgical plans and postoperative care plans, helping to improve surgical success rates and patient outcomes.

[0053] In terms of resource management, the present invention's intelligent device management module and medical care allocation module fill a gap in existing systems. By accurately calculating device utilization efficiency and optimizing staffing, hospitals can more rationally allocate valuable medical resources, ensuring both quality of care and improved resource utilization efficiency. This intelligent resource management approach is crucial for reducing medical costs and improving hospital operational efficiency.

[0054] Furthermore, the intelligent early warning function of this invention, through real-time monitoring of patients' vital signs and calculation of health status indexes, can promptly identify potential risks and provide timely and accurate early warning information to medical staff. This function is particularly important in postoperative care for cardiovascular surgery, significantly improving the efficiency of emergency response.

[0055] In summary, this invention comprehensively improves the quality and efficiency of cardiovascular surgery nursing handovers through the organic integration of information technology, intelligentization, and standardization. It not only addresses practical issues such as poor information transmission, inaccurate risk assessment, and suboptimal resource allocation, but also provides a powerful decision-making support tool for hospital management. This innovative system design is expected to play a significant role in improving medical quality, reducing medical errors, and optimizing resource allocation, positively impacting the development of cardiovascular surgery nursing and the entire medical industry.

[0063] To further illustrate the technical means and effects employed by the present invention to achieve its intended objectives, the following detailed description, along with the accompanying drawings and preferred embodiments, includes a detailed description of the specific implementations, structures, features, and effects thereof. In the following description, references to "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0064] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0065] See Figure 1-7 The present invention relates to an intelligent handover system for cardiovascular surgery nursing and its implementation method, aiming to improve the efficiency and accuracy of handover during cardiovascular surgery nursing. The technical solution and advantages of the present invention will be described in detail below.

[0066] First, the intelligent cardiovascular surgery nursing handover system proposed in this invention includes a receiving terminal 1, an information transmitting terminal 2, an output terminal 3, an information collection terminal 4, an electronic signature terminal 5, and a management terminal 6. These components work closely together to achieve intelligent handover management during cardiovascular surgery. Specifically, the receiving terminal 1, information transmitting terminal 2, output terminal 3, information collection terminal 4, and electronic signature terminal 5 are all connected to the management terminal 6, forming a complete information exchange network.

[0067] Receiving terminal 1 is located in the intensive care unit and includes a first communication terminal device 11. This device features a display module 111 and an electronic signature module 112 for inputting first patient information and obtaining the patient's confirmation signature. This design makes entering and confirming patient information more convenient and accurate. For example, when a cardiovascular surgery patient is transferred from the operating room to the intensive care unit, the receiving nurse can quickly enter the patient's basic information, surgical details, and postoperative precautions using the first communication terminal device 11, and then confirm the signature on the electronic signature module 112, significantly improving the efficiency of shift handovers.

[0068] Secondly, the output terminal 3 is set in the cardiovascular operating room and includes a second communication terminal device 31, a QR code generator 32, a second identification device 33 and a first identification device 34. The second communication terminal device 31 has an input module 311 for inputting the second patient information. The QR code generator 32 is used to generate a QR code for the medical staff's identity. The application of this QR code technology greatly improves the efficiency and accuracy of information transmission. For example, when a cardiovascular surgeon completes the preparation for the operation, he can enter the patient's operation-related information through the second communication terminal device 31, and the system will then generate a QR code containing the doctor's identity and patient information. This QR code can be affixed to the medical record to facilitate subsequent information verification and handover.

[0069] The primary function of Information Transmitter 2 is to record the patient's condition after the second patient is admitted to the ward and transmit it to Receiver 1. This process ensures real-time updates and synchronization of patient information. For example, when a patient is transferred from the operating room to the intensive care unit, the nurse in charge can quickly update the patient's latest status, such as vital signs and medication status, via Information Transmitter 2. This information is immediately transmitted to Receiver 1, ensuring that the receiving nurse is kept up to date with the patient's condition.

[0070] Information Collection Terminal 4 is installed in the cardiovascular operating room as a doctor's station, capturing information about the second patient before and after admission, along with equipment information and medical records. This comprehensive information collection provides a solid data foundation for medical decision-making. For example, during a complex heart bypass surgery, Information Collection Terminal 4 can record in real time the instruments and medications used during the procedure, as well as changes in the patient's various physiological indicators. These detailed records not only facilitate postoperative condition analysis but also provide valuable data support for future improvements to similar surgeries.

[0071] The electronic signature terminal 5 is used to output the electronic signature form to the receiving terminal 1, which is displayed by the receiving terminal 1 and signed for confirmation. This electronic signature process not only improves efficiency, but also enhances the traceability of information. For example, during the patient handover process, the handover parties can view and confirm the various contents of the handover, such as the patient's status, medication status, precautions, etc., through the electronic signature terminal 5, and then sign electronically. This method not only saves the use of paper documents, but also facilitates subsequent inquiries and audits. The electronic signature terminal 5 also includes an information collection module, an instrument information collection module and a central processor for managing instruments;

[0072] The management terminal 6 is responsible for storing the information of the first and second patients and completing information exchange. This centralized information management ensures data consistency and reliability. For example, hospital administrators can use the management terminal 6 to view the real-time status of each cardiovascular surgery patient, including surgical progress and postoperative recovery status, thereby better coordinating medical resources and improving overall medical quality.

[0073] One of the innovations of the present invention is the introduction of an intelligent risk assessment module for calculating the patient's surgical risk index R. The calculation formula is:

[0074] R=α·(W1·P+W2·S+W3·C)+β·(1-e -λ·T )

[0075] In this formula, R represents the surgical risk index, ranging from 0 to 1. P represents the patient's physiological condition score, S represents the surgical difficulty score, and C represents the comorbidity complexity score, all of which range from 0 to 10. T represents the estimated surgical time (hours). W1, W2, and W3 are weighting coefficients, the sum of which equals 1. α is the risk adjustment coefficient, and β is the time impact factor, both ranging from 0 to 1. λ is the time sensitivity parameter, which is used to adjust the impact of time on risk.

[0076] For example, suppose a 65-year-old heart patient requires coronary artery bypass grafting. The doctor's assessment determines the following parameters: P = 7 (patient has a history of hypertension and diabetes), S = 8 (multiple arteries requiring bypass grafting), C = 6 (patient has mild renal insufficiency), and T = 5 hours. Set W1 = 0.3, W2 = 0.4, W3 = 0.3, α = 0.8, β = 0.2, and λ = 0.5. Substituting these into the formula yields:

[0077] R=0.8*(0.3*7+0.4*8+0.3*6)+0.2*(1-e (-0.5*5) )

[0078] ≈0.8*7.1+0.2*0.918

[0079] ≈5.68+0.1836

[0080] ≈5.8636

[0081] The final risk index is approximately 5.86, which can help doctors more objectively assess surgical risks and thus develop more reasonable treatment plans and postoperative care plans.

[0082] In this embodiment of the present invention, the electronic signature terminal 5 also includes a signature confirmation module 51 and an information recognition module 52. The signature confirmation module 51 is used to display and confirm the signature of the medical staff, while the information recognition module 52 is used to set the key points in the electronic signature form that require signature confirmation. This design ensures the standardization and integrity of the signing process. The receiving terminal 1, the information transmitting terminal 2, the output terminal 3, the information collection terminal 4, and the electronic signature terminal 5 also include a camera module that records the signature image, ensuring traceability of the process.

[0083] For example, during the handover process for a heart valve replacement surgery, the electronic signature terminal 5 automatically generates an electronic signature form containing multiple key points based on the specific circumstances of the operation. These key points may include: confirmation of the type of surgery, the type of prosthetic valve used, intraoperative blood loss, and immediate postoperative cardiac function assessment. The doctor and nurse are required to confirm each key point and electronically sign the corresponding location. This design not only ensures that important information is not missed during the handover process, but also provides a reliable basis for potential medical disputes.

[0084] In an embodiment of the present invention, the first identification device 34, the second identification device 33, and the management terminal 6 are all readers. The receiving terminal 1 also includes a first central processing unit 12, a first communication module 13, an information input module 14, and a first display module 15. The output terminal 3 is similarly equipped with a second central processing unit 35, a second communication module 36, an information collection module 37, and a second display module 38. The information collection terminal 4 includes a third central processing unit, a third communication module, an information collection module, and a third display module. The electronic signature terminal 5 includes a fourth central processing unit, a fourth communication module, an electronic signature module, and a fourth display module. The first central processing unit 12, the second central processing unit 35, the third central processing unit, and the fourth central processing unit are all single-chip microcomputers, and each communicates with the outside world through WiFi communication, infrared communication, infrared detection, or electromagnetic induction detection.

[0085] The advantage of this hardware configuration is that it achieves modularization and standardization across all components of the system. For example, in a cardiovascular intensive care unit, the first central processor 12 of the receiving terminal 1 can rapidly process information from multiple beds, while the first communication module 13 ensures real-time communication with other terminals. Furthermore, the first display module 15 clearly displays each patient's key information, enabling medical staff to quickly understand their condition.

[0086] In the embodiment of the present invention, an intelligent equipment management module is introduced to calculate the equipment use efficiency index E. The calculation formula is:

[0087] E=(U·F·(1-D)) / (T·C)

[0088] In this formula, E represents the instrument efficiency index, which ranges from 0 to 1. U represents the number of times the instrument is actually used, F represents the functional integrity of the instrument (0 to 1), D is the instrument loss rate (0 to 1), T is the instrument usable time (hours), and C is the instrument cleaning and preparation time (hours).

[0089] For example, suppose a high-frequency electrosurgical unit is used 12 times in a day's work (U = 12), its functional integrity is 0.95 (F = 0.95), its wear rate is 0.05 (D = 0.05), its usable time is 10 hours (T = 10), and its cleaning and preparation time is 0.5 hours (C = 0.5). Substituting the formula into the equation yields:

[0090] E=(12*0.95*(1-0.05)) / (10*0.5)≈2.166

[0091] This result indicates that the high-frequency electrosurgical unit has a high efficiency, exceeding the ideal state (E = 1). Hospitals can use this index to assess whether they need to add similar equipment or adjust equipment usage and maintenance strategies.

[0092] In an embodiment of the present invention, a method based on the above system is also disclosed, which includes five main steps:

[0093] First, receiving terminal 1 inputs the first patient information, and the medical staff enters the second patient information into output terminal 3. For example, during the admission of a patient with acute myocardial infarction, the emergency physician may enter the patient's basic information, chief complaint, and preliminary diagnosis into receiving terminal 1. Simultaneously, the cardiologist may enter a more detailed examination plan, treatment plan, etc. into output terminal 3.

[0094] The system then compares the two sets of information to ensure consistency. If any inconsistency is found, the system will remind medical staff to recheck the information, which greatly reduces errors in the information transmission process.

[0095] Next, the system generates an electronic signature sheet for medical staff to confirm. This step typically occurs when a patient is transferred from one department to another. For example, when a patient is transferred from cardiology to cardiac surgery, the system automatically generates an electronic signature sheet containing all the patient's important information. Doctors from both departments must sign it for confirmation.

[0096] The fourth step is to complete the patient admission confirmation procedure by identifying the medical staff's identity QR code. This step is particularly suitable for large hospitals and can effectively prevent patients from being mistakenly transferred to other departments.

[0097] Finally, the system collects and transmits various patient information to complete the entire handover process. This includes the patient's latest vital signs, medication status, test results, etc., ensuring that the receiving department's medical staff has a comprehensive understanding of the patient's condition.

[0098] In this embodiment of the present invention, the electronic signature process is further refined. In practical applications, the system incorporates signature confirmation steps at key points in the shift handover process. For example, after verifying the second patient's information with the first patient's, the electronic signature terminal 5 prints an electronic signature form for the medical staff to sign and confirm. This design further enhances the standardization and traceability of the shift handover process.

[0099] In an embodiment of the present invention, the information input and recognition process is described in detail. During this process, the receiving terminal 1 displays the first patient's information. After the medical professional enters the information, the first recognition device 34 identifies this information as medical record information. Simultaneously, the output terminal 3 displays a second patient information entry interface. After the medical professional completes the entry, the system generates a QR code containing this information, which is then recognized by the second recognition device 33. This design significantly improves the accuracy and efficiency of information input and recognition.

[0100] In the embodiments of the present invention, the importance of instrument information is particularly emphasized. In cardiovascular surgery, instrument cleaning, sterilization, and packaging are directly related to surgical safety. Therefore, the system includes a recording function for this information at output terminal 3. For example, for a specialized instrument used in heart bypass surgery, the system will record information such as the last cleaning time, whether it has been sterilized at high temperatures, and whether sterile packaging is required. This information not only helps ensure surgical safety but also provides reliable data support for hospital instrument management.

[0101] In an embodiment of the present invention, the patient information that the system needs to record is listed in detail, including surgical method, admission diagnosis, surgeon, surgeon, anesthesiologist, ASA grade and risk factor, operation time, surgical method, department code, bed number, etc. These comprehensive information records ensure that no important details are missed during the handover process. For example, for a patient who needs to undergo heart valve replacement surgery, the system will record all key information from the admission diagnosis (such as "mitral stenosis") to the specific surgical arrangement (such as "October 1st at 9 am, operating room 3, surgeon Zhang San, anesthesiologist Li Si, ASA grade III"). This detailed information record not only helps medical staff quickly understand the condition of the patient, but also provides a reliable basis for subsequent medical quality evaluation.

[0102] In addition, the present invention also includes an innovative intelligent medical care configuration module, whose optimization objective function is:

[0103] Minimize Z=∑(W i ·X i )+γ·(MN) 2

[0104] Subject to:

[0105] ∑X i =N

[0106] X i ≥0and integer,for all i

[0107] In this optimization model, Z represents the overall configuration cost, W i is the weight coefficient of the i-th type of medical staff, X i represents the number of medical staff of category i, N is the total number of medical staff required, and M is the total number of medical staff available in the hospital. γ is a balancing parameter used to adjust the degree of matching between the number of staff and the available resources of the hospital.

[0108] For example, suppose a large cardiovascular center needs to staff its surgical schedule for the next month. The center has three primary types of medical personnel: cardiovascular surgeons, anesthesiologists, and specialist nurses. The hospital has a total available staff of 100, while the estimated total required staff based on surgical volume is 90. We can set weights: cardiovascular surgeons W1 = 5, anesthesiologists W2 = 4, and specialist nurses W3 = 3, reflecting the scarcity and importance of different types of personnel. We also set the balancing parameter γ = 0.1.

[0109] By solving this optimization problem, we might arrive at the following result: cardiovascular surgeons X1 = 25, anesthesiologists X2 = 30, and specialist nurses X3 = 35. This result not only meets the total headcount requirement (25 + 30 + 35 = 90), but also strikes a balance between different types of personnel while also taking into account the hospital's available resources (100). This intelligent allocation solution can help hospitals optimize human resource allocation while ensuring medical quality.

[0110] Finally, in the embodiment of the present invention, the content of patient information and the requirements for vital sign monitoring are further refined. It is particularly worth mentioning that the system also includes an intelligent early warning module for calculating the health status index H based on the patient's vital sign data. The calculation formula is:

[0111]

[0112] Among them, H is the health status index, ranging from 0 to 1. i represents the normalized value of the i-th vital sign, W i is the weight coefficient of the i-th vital sign.

[0113] For example, for a patient who has just undergone coronary artery bypass graft surgery, we may pay special attention to the following indicators: blood pressure, heart rate, blood oxygen saturation, body temperature and urine output. Assume that the normalized values ​​and weights of these indicators are:

[0114] Blood pressure: V1=0.8, W1=0.3;

[0115] Heart rate: V2=0.7, W2=0.25;

[0116] Blood oxygen saturation: V3 = 0.9, W3 = 0.2;

[0117] Body temperature: V4=0.95, W4=0.15;

[0118] Urine volume: V5 = 0.6, W5 = 0.1;

[0119] Substitute into the formula to calculate: H = (0.8*0.3+0.7*0.25+0.9*0.2+0.95*0.15+0.6*0.1) / (0.3+0.25+0.2+0.15+0.1)≈0.805

[0120] The resulting health index is 0.805, a value that can help medical staff quickly assess the patient's overall health. If this index falls below a preset threshold (for example, 0.7), the system will automatically issue an alarm, reminding medical staff to pay close attention to the patient's condition.

[0121] It is worth noting that in actual applications, if the system detects any abnormality during data collection, output terminal 3 will immediately issue an alarm. At the same time, the intelligent risk assessment module will recalculate the patient's surgical risk index R, which helps medical staff adjust treatment plans in a timely manner.

[0122] In summary, the intelligent cardiovascular surgery nursing handover system and method of the present invention integrates multiple innovative modules to achieve comprehensive intelligent management, from patient information management, risk assessment, equipment management, to staffing. This not only significantly improves the efficiency and accuracy of cardiovascular surgery care but also provides a powerful decision-making support tool for hospital management. For example, the intelligent risk assessment module allows doctors to more objectively assess surgical risks; the intelligent equipment management module allows hospitals to optimize equipment utilization; and the intelligent medical and nursing configuration module allows managers to more effectively allocate human resources.

[0123] Furthermore, the system's modular design makes it highly scalable and adaptable. Hospitals can adjust the parameters of each module or add new functional modules based on their needs. For example, specific risk factors could be added to the risk assessment module for specialized cardiovascular surgeries, or the weighting coefficients for vital sign monitoring could be adjusted according to different seasons.

[0124] Finally, this invention is not only applicable to cardiovascular surgery care but can also be extended to other complex medical scenarios. Through appropriate adjustment and customization, this system can provide strong support for nursing handover in other specialized surgeries, thereby comprehensively improving the overall medical quality and management level of the hospital.

[0125] Although the above describes the specific embodiments of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without any creative work are still within the scope of protection of the present invention.
