The present application belongs to the technical field of driving devices and in particular relates to a peristaltic pump and a nursing instrument. The peristaltic pump of the present application comprises a housing, an electric motor and a first catheter. The housing is provided with an abutting portion in an inwardly extending manner. A rotating shaft of the electric motor is inserted in the housing. A trench is formed between the abutting portion and an eccentric wheel. Two ends of the first catheter extend to a catheter opening. The eccentric wheel rotates along with the rotating shaft to press the first catheter to abut against the abutting portion, such that the first catheter conveys a liquid. The electric motor works, such that the rotating shaft rotates, and the rotating shaft drives the eccentric wheel to rotate and press the first catheter outside the eccentric wheel, and the atmospheric pressure in an external container is out-of-balance, such that a liquid in the container can be sucked in from one end of the first catheter and pumped out from the other end of the first catheter, that is, the liquid in the external container is discharged; and when the liquid in the first catheter needs to be recycled into the container, the electric motor is enabled to work reversely, and the eccentric wheel reversely presses the first catheter, such that the liquid in the first catheter flows back into the container.La présente invention se rapporte au domaine technique des dispositifs d'entraînement, et concerne en particulier une pompe péristaltique et un instrument de soins infirmiers. La pompe péristaltique de la présente invention comprend un boîtier, un moteur électrique et un premier cathéter. Le boîtier est pourvu d'une partie de butée d'une manière s'étendant vers l'intérieur. Un arbre rotatif du moteur électrique est inséré dans le boîtier. Une tranchée est formée entre la partie de butée et une roue excentrique. Deux extrémités du premier cathéter s'étenden
