Abstract
The utility model discloses an eccentric wheel plunger infusion pump which comprises a pump head unit, a plunger pump unit, a plunger pump unit and a plunger pump unit. One end of the plunger rod penetrates through the pump head unit and then extends into a pump cavity of the pump head unit; the linear driving mechanism is connected with the other end of the plunger rod and is used for driving the plunger rod to do reciprocating linear motion in the pump cavity of the pump head unit; the linear driving mechanism is an eccentric wheel driving mechanism and converts rotary motion into reciprocating linear motion through an eccentric wheel so as to drive the plunger rod to act. The device has the advantages of simple structure, low processing and manufacturing cost, simplicity and convenience in maintenance, high reliability and the like.
