Abstract
A linear peristaltic device for pumping medical solutions to a patient comprises a hinged pivot or hinged attachment between the peristaltic drive mechanism and its associated platen. An IV tube, through which the medical solutions are to be pumped is received and held between the peristaltic drive mechanism and the platen during operation of the device. The device also includes a compliant means which normally urges the peristaltic mechanism toward the platen but which yields, as necessary, to limit the force the peristaltic mechanism can exert against the tube.
