  10. 10. The intelligent control method according to claim 6, further comprising: After receiving the feeding data, the mobile terminal adopts an increment learning algorithm to update the single safety threshold and the swallowing interval time parameter on line based on a historical feeding sample set, wherein the updating weight is adaptively adjusted according to the feeding times of the patient, the alarming frequency and the rehabilitation evaluation result.

Description

Intelligent weighing feeding bowl and intelligent control method thereof Technical Field The specification relates to the field of medical care, in particular to an intelligent weighing feeding bowl and an intelligent control method thereof. Background Dysphagia (DYSPHAGIA) is one of the common complications of patients suffering from cerebral apoplexy, parkinson's disease, alzheimer's disease and other neurological diseases, and is mainly manifested by delayed swallowing reflex, dystonia and reduced throat control capacity, which leads to serious consequences of easy aspiration, choking cough and even choking of patients in the feeding process. For such patients, the core of safe feeding is the precise control of the amount of food in each feeding port, the so-called "bite-size". If the amount of one mouth is too small, swallowing reflex may not be effectively triggered, so that food stays in the oral cavity or the pharynx, while if the amount of one mouth is too large, high-risk events such as aspiration, airway obstruction and the like are extremely easy to occur, and choking or inhalation pneumonia can be caused in severe cases. At present, the method for controlling 'one-mouth' in clinical and home care scenes is still original, and mainly has the following defects: (1) The traditional tableware relies on empirical operation, namely, the tableware such as a common soup spoon, a tea spoon and the like is inaccurate in capacity, nursing staff or patients often take food by visual estimation, the influence of subjective judgment and hand stability is great, and accurate control is difficult to realize; (2) Although the medical injector or the feeder can realize certain quantitative control, the use mode is unnatural, the medical injector or the feeder is easy to cause the patient to feel opposite or contradict, and the flow rate is rough to adjust, so the medical injector or the feeder is not suitable for oral feeding training; (3) The function of the quantitative feeding spoon or the quantitative cup is single, the existing product generally only limits fixed capacity, lacks dynamic control functions of feeding speed, interval time and swallowing rhythm, and cannot be intelligently adjusted according to the state of a patient; (4) The high-end nasal feeding pump equipment has the advantages of large volume and high cost, is mainly used for feeding through a nasal tube or a stomach tube, and is not suitable for oral rehabilitation feeding scenes; (5) The core problems of the existing intelligent tableware are not solved, although part of conceptual intelligent tableware integrates a weighing or timing function, two key defects generally exist, namely, the bowl body is easy to move to cause unstable weighing data, and an active safety early warning mechanism in the event is lacking and cannot be intervened in time when excessive or excessively fast food taking actions occur. Therefore, there is a need to provide an intelligent weighing feeding bowl and an intelligent control method thereof, which at least solve some of the above problems.
