Therefore, the diaper type evacuation device can delay the spread of bad smell of the excrement to the periphery as much as possible and can prevent the excrement from staining or being spread to bedclothes and clothes such as a patient gown of the user. According to the present invention, the diaper type evacuation device includes: a bottom wearing unit including a wearing main body worn on the bottom of the user and a wearing unit for evacuation extended to the anus while having a reduced width in comparison with the wearing main body, wherein the wearing unit for the evacuation has an inclined groove to lead the excrement to the lower side by receiving the excrement discharged when the user defecates and the bottom wearing unit has elasticity； an excrement pocket connected to the bottom wearing unit while having an evacuation hole corresponding to the inclined groove and receiving and accommodating the excrement led along the inclined groove after passing through the evacuation hole, wherein the excrement pocket is waterproof； and a nonslip plate installed on the inner side of the excrement pocket while having an uneven surface to suppress the movement of the excrement in the excrement pocket.본 발명은 사용자가 둔부에 착용한 상태에서 배변 시 배출된 대변이 방수형의 주머니 내에 역류가 최대한 방지되는 상태로 수용됨에 따라, 배변 후 즉시 교체하지 않더라도 사용자의 둔부 및 기저귀에 대변이 묻거나 번지는 현상이 방지되고 이에 따라 사용자의 환자복 등 의복 및 이불 등의 침구에 대변이 묻거나 번지지 않게 되는 동시에 대변의 악취가 주변으로 퍼지는 것을 최대한 지연시킬 수 있는 기저귀 타입의 배변용 장치에 관한 것으로서, 본 발명에 따른 기저귀 타입의 배변용 장치는, 사용자의 둔부에
