Device for administering of medication in fluid form
First Claim
1. A device for administering a medication in fluid form, said device comprising:
- an outlet;
a storage means for storing a fluid;
first and second individual communications each of which being in fluid communication with said storage means and said outlet;
each communication comprising at least one flow restricting means for restricting a flow, wherein said restricting means has no capability to stop the flow completely;
at least one valve arranged in fluid-connection to at least one of said flow restricting means; and
wherein the device downstream of said communications further comprises a container for storage and supply of a medication in fluid form, said container comprising a fluid chamber and a medication chamber being arranged relative to each other so that when the volume of the fluid chamber increases the volume of the medication chamber decreases.

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 farther contains a holding device for bolus rate of infusion for a short period. 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.
