Abstract
A syringe pump comprises a housing and a retainer mounted thereon for receiving a syringe. The syringe to be received is of the type including a barrel for holding liquid medication and a plunger movably positioned in the barrel for expelling the liquid medication therefrom. A driver is movably mounted on the housing for engagement with the plunger and for pushing the plunger into the barrel to thereby force the liquid medication out of the barrel. A control mechanism within the housing regulates the movement of the driver against the plunger. This thereby regulates delivery of the liquid medication from the barrel. Depressible actuation buttons or switches are mounted on the housing for manual access by a user. These switches are associated with the control mechanism to permit the user to select one or more functions under which the control mechanism is to operate. The actuation switches include an electrically conductive material positioned to contact the control mechanism when depressed by the user. This depression causes an electrical energization or de-energization of the control mechanism for the operation of the selected function.
