The advantages of the detachable design of the BN-V (Detachable Fiber Optic Laryngoscope). In terms of cleaning and disinfection, the detachable structure allows individual components of the laryngoscope, such as the fiber optic assembly and laryngoscope blade, to be disassembled separately. This enables thorough cleaning and disinfection, avoiding hard-to-reach areas caused by tightly connected parts and reducing the risk of cross-infection, making it particularly suitable for environments like hospitals where stringent disinfection is required. Secondly, from a maintenance and repair perspective, if a component of the BN-V (Detachable Fiber Optic Laryngoscope) malfunctions or is damaged, the detachable design allows for the replacement of that specific part without needing to replace the entire laryngoscope. This lowers usage costs while also enhancing the flexibility and lifespan of the laryngoscope.
