Description

Technical Field

[0001] The present invention belongs to the technical field of medical information systems, and in particular is a systematic nursing analysis method for intraoperative pressure injuries. Background Art

[0002] Intraoperative pressure injury, also known as intraoperative pressure sore or intraoperative pressure ulcer, refers to the damage to the skin and / or deep tissue caused by prolonged local pressure on the patient during surgery. Intraoperative pressure injury is the skin and soft tissue damage caused by prolonged pressure, shear force or friction on the patient's body parts during surgery. This situation usually occurs in the area of ​​bony prominence or the area that is compressed due to the surgical position; in order to reasonably evaluate whether pressure injury occurs during surgery, a systematic nursing analysis method for intraoperative pressure injury is needed;

[0003] A Chinese patent application numbered CN118609758A discloses a method, device, equipment and medium for predicting surgically acquired pressure injuries, which relates to the technical field of surgically acquired pressure injury prediction, and includes: obtaining preoperative clinical indicators of preoperative patients including patient physical condition information and patient disease characteristic information, inputting the preoperative clinical indicators into a first surgically acquired pressure injury prediction model, and predicting the risk of surgically acquired pressure injury for the preoperative clinical indicators through the first surgically acquired pressure injury prediction model, and obtaining a corresponding first risk prediction result; if the first risk prediction result is a high-risk result, taking corresponding preventive measures for the patient before and during the operation; inputting the intraoperative clinical indicators generated by the patient during the operation into a second surgically acquired pressure injury prediction model, and predicting the risk of surgically acquired pressure injury for the intraoperative clinical indicators through the second surgically acquired pressure injury prediction model, and obtaining a corresponding second risk prediction result;

[0004] However, it ignores the impact of dangerous conditions of the patient's body position and compression position on compression injuries, resulting in the inability to conduct a comprehensive assessment and analysis of the dangers of the patient's body position and compression position during the surgical simulation before surgery. At the same time, it is impossible to comprehensively analyze the patient's compression injuries during surgery based on the patient's physical risk information, resulting in low accuracy and warning efficiency of compression injury analysis.

[0005] In order to solve the above problems, the present invention designs a systematic nursing analysis method for intraoperative pressure injuries. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention proposes a systematic nursing analysis method for intraoperative pressure injuries. The present invention obtains the patient's surgical process data, the patient's physical information and the patient's pressure position data to predict the abnormality of the pressure position, obtains the patient's physical characteristic data to analyze the impact of physical abnormalities, and comprehensively analyzes the impact of physical abnormalities and the prediction results of the abnormal pressure position to perform injury analysis. Based on the injury analysis results, an injury warning is performed, and it is determined whether the pressure position needs to be protected. Before the operation, a comprehensive assessment and analysis of the dangers of the patient's body position and the pressure position in the surgical simulation process is performed. At the same time, the patient's physical risk information is combined to perform the pressure injury analysis of the patient during the operation, thereby improving the accuracy of the pressure injury analysis and the warning efficiency.
