The body includes a longitudinal bore and a defense ring extending annularly around the body. The ring includes an upper surface, a lower surface including an abrasive area for scraping a body surface, and an interior receptacle for collecting material scraped from the body surface. The canister is disposed within the longitudinal bore and includes a nozzle for discharging the self-defense fluid. The whistle includes a mouthpiece and a housing coupled to the spray canister. The housing includes a quick release mechanism for removably attaching the housing to the body and maintaining the canister in a fixed position within the housing. The mouthpiece is pivotally connected to the housing enabling pivoting about the housing to provide access to the nozzle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Self-defense device","description":"A self-defense device includes a body, a self-defense spray canister within the body, a whistle coupled to the body and the canister, and a light source within the body.
