Abstract:
1. A micropump of a peristaltic type that continuously transfers a fluid through depression of an elastic tube, the micropump comprising: a tube unit configured to at least include the tube in which the fluid is transferred, a tube guide frame that fixedly holds the tube, and a tube individual data storage section that stores therein tube individual data; a depression mechanism section having a rotation cam that sequentially deforms portions of the tube to transfer the fluid along a length of the tube; a control unit that is attachable/detachable to/from the tube unit, and at least includes a control circuit section that drives and controls the tube and control units, via a transmission mechanism section, a motor for driving the depression mechanism section, and a tube individual data processing section including a reader/writer unit that reads the tube individual data for data processing thereof; and a power supply that makes an electrical supply to the control unit, wherein the reader/writer unit detects attachment of the tube unit to the control unit and sends the tube individual data to the control unit, the tube individual data is used as a basis for controlling and driving the tube and control units, the rotation cam sequentially depresses a plurality of depression members with respect to the tube from an inflow side to an outflow side thereof, the rotation cam is configured by a first cam that is fixed to a center shaft and a second cam that is pivotally supported by the center shaft, and the second cam is able to move from a position where the tube is free from the depression members to a position where the tube can be depressed thereby.
