Description

Intelligent speed-regulating anti-leakage device for intravenous transfusion and working control method thereof Technical Field The invention relates to the technical field of clinical transfusion nursing equipment, in particular to an intelligent speed-regulating anti-leakage device for intravenous transfusion and a working control method thereof. Background Intravenous infusion is one of the most commonly used modes of administration in clinical treatment, and plays an irreplaceable role in disease treatment, nutritional support and the like. However, the current clinical transfusion still has a plurality of pain points in the aspects of speed regulation precision and anti-leakage prevention and control, and seriously affects the treatment effect and the safety of patients. In the speed regulation link, the traditional transfusion speed regulation depends on a roller type flow regulator, has low regulation precision, is easily influenced by body position change and the height of a transfusion bottle, and cannot realize real-time calibration. For the scenes of needing strict speed control of chemotherapeutic drugs, antibiotics, nutrient solutions and the like, the traditional regulator is difficult to meet the accurate drug administration requirement, and can cause the fluctuation of blood concentration, influence the treatment effect and even cause adverse reactions. Although the existing part of intelligent infusion pumps can realize accurate speed regulation, the equipment cost is high, the operation is complex, the intelligent infusion pumps are difficult to popularize in the scenes of primary hospitals, clinics and the like, and most intelligent equipment has poor compatibility with the traditional infusion apparatus, and special consumable materials are required to be matched, so that the clinical use cost is increased. In the anti-leakage link, the intravenous transfusion leakage is a common clinical complication, and the reasons include that the needle head slides out of a blood vessel, the wall of the blood vessel is damaged, the transfusion pressure is too high, and the like. Traditional seepage prevention and control mainly relies on manual inspection of nurses, and not only intensity of labour is big, and the leak detection rate is high, especially under nursing at night, many patients simultaneously nursing scene, is difficult to realize the timely discovery of seepage. After the liquid medicine leaks to the tissue outside the blood vessel, local tissue may be red, painful and necrotic, and nerve damage and dysfunction may even be caused in serious cases, especially after leakage, the harm is more serious due to the liquid medicine such as chemotherapeutics, hypertonic nutrient solution and the like. Most of the existing leakage monitoring devices are designed in a single function, or are large in size, complex in operation, low in monitoring sensitivity and long in alarm delay, and most of the devices and the puncture fixing device lack of cooperation, so that the full-flow prevention and control of source prevention-real-time monitoring-timely blocking are difficult to realize. In addition, most of the existing speed regulation and anti-leakage devices are independently designed and lack a linkage control mechanism. Meanwhile, the existing equipment has insufficient suitability for special groups (such as pediatric and geriatric patients), and the problems that the needle is easy to scratch by the pediatric patient, the body position of the geriatric patient is changed frequently and the like are not effectively solved, so that the infusion risk and the nursing difficulty are further increased. Therefore, there is a need to develop an intelligent device which has the functions of accurate speed regulation and full-flow antiseep, is adaptive to multiple scenes and special people, has controllable cost and is compatible with the existing equipment, so as to solve the core pain point in clinical infusion care and improve the infusion safety and nursing efficiency. Disclosure of Invention The invention aims to provide an intelligent speed-regulating anti-leakage device for intravenous transfusion and a working control method thereof, which realize accurate regulation of transfusion flow rate and full-flow prevention and control of leakage risk, and simultaneously give consideration to clinical practicality, compatibility and cost controllability, and solve the problems of low speed regulation precision, leakage monitoring lag, poor equipment compatibility, insufficient suitability and the like in the prior art. The invention provides a technical scheme of an intelligent speed regulation anti-leakage device for intravenous infusion, which is characterized by comprising a speed regulation module, an anti-leakage monitoring module, a pressure protection module, a control module and an interaction module, wherein the speed regulation module comprises a mechanical speed regulation unit or an intellig
