Nursing staff need to move back and forth between workstations, frequently switching between multiple screens and physical buttons, increasing the ineffective moving distance of medical staff and causing fatigue among nursing staff; and there are the following defects in actual applications;

[0003] 1. Traditional nursing workstations generally consist of a single workbench, responsible for patients in one department. When there are too many patients to be connected, it is easy to cause chaos in patient information entry, and they do not have the function of storing and retrieving drugs. For daily medication, it is still necessary to go to the pharmacy to pick up, increasing the workload of nursing staff. Moreover, for the existing drug management methods, open medicine shelves or independent refrigerated cabinets are mostly used. Drug classification relies on manual labels, with low storage and retrieval efficiency. The overall compressor refrigeration cannot achieve precise temperature control in different areas, and the activity loss rate of biological agents is high;

[0004] 2. Existing vital sign monitoring devices rely on wired electrocardiogram monitors and blood oxygen probes. Patients are restricted in movement, with a high risk of wire entanglement and signal loss rate, and lack the function of synchronizing monitoring data with the display screen of the nursing workstation, making it impossible for nursing staff to timely obtain patient vital sign data to take corresponding measures.

[0030] The present invention will be further described below in conjunction with the accompanying drawings and some embodiments.

[0031] In Figures 1 - 10In this case, a ring-shaped intelligent nursing workstation is provided, including a ring-shaped workbench 1; the ring-shaped workbench 1 is composed of multiple nursing cabinets 2. The nursing cabinet 2 is of a fan-shaped structure. An electromagnetic suction device is arranged on the side wall of the nursing cabinet 2.
