Abstract
An infusion device for continuously 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 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.

37. A device for administering a medication in fluid form, said device comprising:
-
an outlet means and a storage means for storage of a fluid;
two individual communications each of which being in fluid communication with said storage means and said outlet means;
each communication comprising at least one flow restricting means;
at least one valve means arranged in fluid-connection to 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 volume of the fluid chamber increases the volume of the medication chamber decreases. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 52)

51. A flow regulating device comprising:
a passage defined by at least a first element and a second element; and
wherein at least one of the first and second element is a primary deformable element adapted, when affected by a force in a first direction, to be elastically deformed in a second direction with a substantially constant volume, so as to change the cross sectional area of the passage, said first direction being transverse to said second direction.- View Dependent Claims (53, 54, 55, 56, 57, 58)

59. A device for supervising flow in restricting means the device comprising a first chamber, a second chamber and a third chamber, the first chamber being separated from the second chamber by a first membrane and from a third chamber by a second membrane, and
the second chamber being in fluid communication with the supply-side of a first restricting means; -
the first chamber being in fluid communication with the discharge-side of the first restricting means and the supply-side of a second restricting means; and
the third chamber being in fluid communication with the discharge-side of the second restricting means. - View Dependent Claims (60, 61, 62, 63, 64)
