The present disclosure relates to the technical field of a driving device, and more particularly to a peristaltic pump and a care instrument. The peristaltic pump includes: a casing, a motor, and a first conduit with a first end and a second end. The casing extends inwards to form an abutment portion. A rotational shaft of the motor is inserted into the casing. A groove is formed between the abutment portion and the eccentric wheel. Two ends of the first conduit extend through the conduit opening. The eccentric wheel is configured to press the first conduit into abutment against the abutment portion along with the rotation of the rotational shaft to enable the first conduit to deliver a liquid. The motor operates to enable the rotational shaft to rotate, the rotational shaft further drives the eccentric wheel to rotate and press the first conduit disposed at the outer side of the eccentric wheel, unbalancing the air pressure within the external storage container, and enabling the liquid within the storage container to be sucked into the first end of the first conduit and then pumped out from the second end of the first conduit, that is, the liquid in the external storage container is discharged out. When it is needed to recover the first conduit into the storage container, the motor is enabled to operate in the reverse direction, the first conduit is then pressed by the eccentric wheel towards a reverse direction, which further enables the liquid in the first conduit to flow back into the storage container.
