This paper explores and analyses the interactive home geriatric two-way video health care system, investigates and analyses the daily lives and behaviours of the elderly in their homes through research interviews, obtains the main needs of the elderly population in their lives, as well as their cognitive and behavioural characteristics, and proposes four service function modules for the elderly in their homes; then, combining service design and interaction design theory, we propose the following four service modules for the elderly in their homes. Given the design methods and processes of the intelligent service system for the elderly at home as well as the interface interaction design principles on the three levels of vision, interaction, and reflection, the intelligent service system platform for the elderly at home was constructed, the interaction design of the mobile device terminal software of the service system platform practiced in the form of APP, and the eye-movement experiment method and fuzzy hierarchical analysis were applied to the design of the intelligent service system for the elderly at home from qualitative and quantitative perspectives. The thesis study provides a new way of thinking to design and provide intelligent service system products for the elderly living at home, which is an important contribution to society’s care for the elderly and their quality of life. The key features of the human skeleton are extracted from the model of abnormal leaning and falling behaviour of the elderly, and the SVM machine learning method is used to classify and identify the data, which enables the identification of the abnormal behaviour of the elderly at home with an accuracy of 97%.
Objective. To explore the influence of PDCA cycle nursing based on network service on the quality of life and nutritional status of hypertension patients in home care. Methods. From January 2019 to December 2020, 116 hypertension patients in home care were selected as research objects. According to the random number method, the patients were divided into two groups: the control group (n = 58) and the observation group (n = 58). The control group was given routine home care service, while the observation group was given PDCA cycle nursing based on the network service. The effects of blood pressure control, quality of life, nutritional status, and emotional state of the two groups were analyzed. Results. The effective rate of blood pressure control in the observation group (93.10%) was higher than that in the control group (79.31%) ( P < 0.05 ). After intervention, the Generic Quality of Life Inventory-74 scores of the observation group were higher than those of the control group ( P < 0.05 ). After intervention, the malnutrition-inflammation score of the observation group was lower than that of the control group ( P < 0.05 ). After the intervention, the Self-Rating Anxiety Scale score and Self-Rating Depression Scale score of the observation group were lower than those of the control group ( P < 0.05 ). Conclusion. PDCA cycle nursing based on network service has a good blood pressure control effect on hypertension patients in home care, which can improve their quality of life and nutritional status and also relieve their bad emotions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
