Abstract
An infusion device for continuous infusion of medication is disclosed, in which infusion is controlled over two separate fluid communications. The infusion is in each fluid communication controlled by restricting means and valve means, and one of the fluid communications further contains a holding device for bolus rate of infusion. The device comprises a flow regulating device comprising a passage defined by at least a first element and a second element, wherein at least one of the first and second element is a primary deformable element adapted to be elastically deformed so as to change the cross sectional area of the passage. Furthermore the device comprises a container for storage and supply of a medication in fluid form, said container comprising a first and a second chamber being arranged relatively to each other so that when volume of the first chamber increases the volume of the second chamber decreases.
