Intelligent wristband data synchronization method and system for preoperative safety check Technical Field The invention relates to the field of intelligent wristbands, in particular to an intelligent wristband data synchronization method and system for preoperative safety check. Background In the medical field, preoperative safety check is a key link for guaranteeing patient operation safety and avoiding medical errors. Along with the continuous promotion of medical informatization construction, the traditional preoperative safety check mode gradually exposes a plurality of problems, and the requirements of high efficiency, accuracy and safety of modern medical treatment are difficult to meet. Traditional preoperative safety check mainly relies on manual operation, and medical staff confirms the identity of a patient, operation information and the like through oral inquiry, paper medical record nuclear and other modes. The method is low in efficiency, consumes a large amount of manpower and time, is easy to cause human negligence and error in the checking process, and medical staff can cause inaccurate checking information due to fatigue, inattention and other reasons, so that serious medical accidents such as surgical position errors, patient identity confusion and the like are caused. Traditional verification methods lack an efficient data logging and traceability mechanism. Once a medical error occurs, the problem source is difficult to quickly and accurately find, and powerful evidence support cannot be provided for the treatment of medical disputes. Meanwhile, in the patient transferring process, due to the lack of real-time information interaction and monitoring means, the patient cannot be ensured to be transferred to an operating room at the right time according to the right flow, and the operation risk is increased. The existing preoperative safety checking flow requires a plurality of links to be manually operated by medical staff, is complex and is easy to cause human negligence and errors. Meanwhile, an automatic checking mechanism is lacking, and the multi-party real-time common checking cannot be realized, so that the checking efficiency is low, and the smooth operation is affected. Under the sudden conditions of wristband reading failure and the like, the prior art lacks an effective emergency treatment mechanism, and can not acquire core information of a patient in time, so that the operation is ensured to be continued. Meanwhile, the problems of state recovery and data synchronization after emergency treatment are not effectively solved, and subsequent medical operation is easily affected. Therefore, we propose a smart wristband data synchronization method and system for preoperative security check to solve the above-mentioned problems.
