Blowdown device and nursing bed thereof

The invention relates to the technical field of medical care, and in particular relates to a blowdown device and a nursing bed thereof. The blowdown device comprises dirt collecting hopper, a dirt collecting box which is connected with the dirt collecting hopper through a dirt discharging pipe and used for collecting dirt discharged from the dirt collecting hopper, and an inserting plate which isused for sealing the dirt collecting hopper, so that pollution gas in the dirt collecting hopper cannot escape. A cavity is formed in the inserting plate. A flushing hole communicated with the dirt collecting hopper is formed in the lower side of the cavity. The blowdown device and the nursing bed have the advantages that the inserting plate can be driven by an opening and closing assembly, and the switch is arranged on one side of the bed head; a water pump is provided with a switch on one side of the bed head; a patient can excrete in a self-service manner without the help of any nursing personnel, which effectively reduces the working intensity of nursing personnel; and dirt excreted for multiple times does not need to be cleaned immediately, but can be cleaned at one time after being excreted for multiple times, so that the working intensity of nursing personnel is reduced.
