Within 3h of stroke onset and expected to be able to start receiving the investigational product within 3 h of stroke onset (note: stroke onset time was calculated from the onset time of stroke symptoms; if stroke onset occurs during sleep, the stroke onset time should be taken as the latest normal appearance time); 5. First stroke onset, or have a history of stroke but good prognosis (mRS score ≤1); 6. Subjects who are able to understand and comply with the study procedures, and who agree to sign the study informed consent form in writing to indicate that they are willing to participate in the trial (the informed consent form can be signed by subjects or their legal representatives).

Expected survival period is less than 3 months; 14. Pregnant, planning pregnancy or breastfeeding patients; 15. Suspected or confirmed history of alcohol or drug abuse; 16. Participated in other drug or device clinical trial within the 3 months prior to screening or are participating in a other clinical trial; 17.
