Description

Insulin pump safety reminding system based on remote communication Technical Field The invention relates to the technical field of intelligent medical treatment and remote monitoring, in particular to an insulin pump safety reminding system based on remote communication. Background Insulin pumps are used as the main equipment for continuous subcutaneous insulin infusion, and accurate and reliable operation of the insulin pumps is critical for the blood glucose stabilization of diabetics. Although the traditional insulin pump has the local audible and visual alarm function (such as liquid medicine exhaustion, pipeline blockage, too low electric quantity and the like), the traditional insulin pump has obvious defects in actual clinical application, especially in home scenes: The alarm information is islanding, namely the alarm is only triggered on the equipment, if a patient cannot perceive the equipment due to hearing impairment, sleep, temporary distance from the equipment or in a noisy environment, the alarm is invalid, serious hyperglycemia or hypoglycemia events can be caused, and the potential safety hazard is prominent. The lack of active early warning and trend judgment is that the existing warning is mostly based on the passive response of the instantaneous threshold (such as the electric quantity is lower than 10%), the early risk prediction (such as the prediction of the insulin to be exhausted or the risk of hypoglycemia according to the infusion mode) can not be performed based on the historical data and the running trend, and the preventive is insufficient. Outside hospital monitoring is absent, and after the patient leaves the hospital, insulin pump data form an 'information island'. The main doctor can not acquire the real treatment compliance and the equipment running condition of the patient in time, and can only review limited data in the re-diagnosis process, thereby losing the opportunity of continuous medical monitoring and timely intervention. Remote assistance capability is blank in that when a patient (such as an elderly person, a child or a visually impaired person) faces an alarm of the device or needs to perform complex operations (such as temporary basic rate setting), family members or medical staff can only perform difficult and inefficient oral guidance through telephone, and misunderstanding and operation errors are easy to generate. At present, a technical means for providing remote state checking and auxiliary operation for authorized personnel on the premise of ensuring safety and compliance is lacking. The multi-role coordination is difficult, namely, patients, family members, community doctors, hospital nurses and attending doctors lack a shared and coordinated information platform, and effective care force cannot be formed. Therefore, an integrated system capable of realizing real-time data aggregation, intelligent analysis and early warning, multi-terminal collaborative reminding and supporting safety remote monitoring is urgently needed in the industry so as to break through the space-time limit of traditional insulin pump management and construct a novel whole-course safety management mode with a patient as a center and a hospital as a support. Disclosure of Invention The invention aims to provide an insulin pump safety reminding system based on remote communication, which solves the technical problem that the traditional insulin pump alarm information cannot reach multiple related parties such as patients, families, medical teams and the like in time, and ensures that the alarm information is not missed and the safety risk is reduced through a multi-terminal cooperative early warning mechanism. In order to achieve the above purpose, the invention provides an insulin pump safety reminding system based on remote communication, which comprises an insulin pump terminal, a patient monitoring terminal, a grading authorized user terminal, a hospital integrated management platform and a safety communication and control center; the insulin pump terminal is used for collecting equipment operation parameters and uploading the equipment operation parameters through safe near field communication, and receiving and executing checked operation instructions; the patient monitoring terminal is in communication connection with the insulin pump terminal and is used for bridging data transfer, local data encryption caching, hierarchical early warning display and a remote human-computer interaction interface of the insulin pump terminal and the hospital integrated management platform; The hierarchical authorized user terminal is used for receiving early warning information related to the insulin pump terminal, checking the state of a patient and initiating a remote operation request; The hospital integrated management platform is in communication connection with the patient monitoring terminal and the grading authorized user terminal and is used for accessing and managing each terminal,
