[0015] 1. A medical hand disinfection device is provided with a rotating drum and a brush. When the hands to be disinfected are placed in the rotating drum, the delivery pump and the driving motor are started. The delivery pump delivers disinfectant to the annular tube through the infusion tube and sprays it out through the nozzle. At the same time, the driving motor drives the first rotating shaft to rotate at a low speed, and drives the second rotating shaft to rotate synchronously through the synchronous wheel and the synchronous belt, so that the two rotating drums rotate synchronously, and then the hands are cleaned by the brush. The brush fits the hands better, and can perform all-round cleaning and disinfection of the hands of medical staff. The bristles of the brush can penetrate into the fingers for cleaning, so that the disinfection of the hands is more comprehensive.

[0016] 2. This medical hand disinfection device has a drainage hole in the drum. When the hand washing and disinfection is completed, the driving motor increases the speed, so that the speed of the rotating drum is increased, and the disinfectant adhering to the brush and the drum is quickly dried, so as to prevent the disinfectant adhering to the brush and the drum from causing bacterial reproduction after the disinfectant becomes ineffective, thereby reducing the disinfection effect.

[0017] 3. This medical hand disinfection device is provided with a rotating disk and a transmission disk. When the hand cleaning and disinfection is completed, the driving motor increases the rotation speed, so that the rotating disk rotates rapidly with the second rotation. Under the action of centrifugal force, the sliding pin slides out from the inside of the rotating disk, and is plugged into the connecting pin groove at the same time, and drives the transmission disk and the third rotating shaft to rotate, thereby causing the fan to rotate. At the same time, the heating wire heats the air inhaled by the fan. When the heated air is sent into the disinfection chamber through the fan and the air inlet pipe, the hands, the disinfection chamber, the spin-drying drum and the brush are heated and dried to prevent microorganisms from breeding in the disinfection chamber where the disinfectant is ineffective.
