A regionally integrated emergency stroke unit includes an information interaction area, an imaging examination area, and a thrombolytic therapy area. A doctor workstation, a comprehensive information surveillance monitor, and a process support artificial intelligence (AI) assistant are set in the information interaction area. A test device, a first television display, a movable low-field magnetic resonance imager, and an AI-assisted decision-making system are set in the imaging examination area. The process support AI assistant performs, via voice interaction or touchscreen keying interaction, automatic inquiry and auxiliary nervous system scale scoring, and further provides real-time retrieval support for a knowledge base and a clinical guideline. The AI-assisted decision-making system is configured to assist in decision-making based on an automatic inquiry result, a scale score result, the test result, and magnetic resonance imaging results of the head and neck, to generate and display a therapy regimen.

This disclosure relates to a horizontal whole body chamber (HWBC) for conducting whole-body exposure analyses therein. The HWBC is configured to provide a uniform distribution of a test material within an air flow to achieve reliable whole body exposure. The HWBC achieves uniform mixing over short distance lengths to provide whole body exposure chambers that are practical for smaller animals and lessen the consumption of laboratory space.
