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.

Device for administering of medication in fluid form

A micro fluidic system comprising at least one tube (), a membrane () and at least one fitting member (). The fitting member () is positioned around the membrane () and an end part () of the tube(s) (), thereby fitting the membrane () to the end part(s) (). The fitting member(s) () is/are made from a shrinkable material, and it/they is/are fitted tightly around the membrane () end part(s) (). This is obtained by causing the shrinkable material to shrink, e.g. by heating the material, while the fitting member () is positioned around the membrane () and the end part(s) (). It is an advantage that the fitting member () is made from a shrinkable material because this provides the possibility of fitting the membrane () tightly to the end part(s) () in an easy and cost effective manner. The micro fluidic system is very suitable for use in a probe, such as a dialysis probe. Also claimed is a method of manufacturing the micro fluidic system.

Micro fluidic system and a method of attaching a membrane to a tube

In a capillary carrier with an inlet and an outlet, a channel is formed and extends between the inlet and the outlet. At least one capillary tube is arranged within the channel, and sealing elements, by which the capillary tube is sealingly fixed to the channel, are arranged at least near an inlet portion and an outlet portion of the capillary tube. An area is formed limited by a part of the channel, the sealing elements and the exterior of the capillary tube, which is in connection with the exterior of the carrier through a fluid communication pad, whereby a possible fluid leak across the sealing elements will be led to this area, and from there to the exterior of the carrier.

Capillary carrier with leak supervision

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.

The present invention relates to apparatus for delivering a controlled or restricted flow of liquid and limiting bubble fragmentation at the inlet. This is achieved in flow restrictor with a flow channel having over most of its length a substantially constant, minimum hydraulic diameter D=4A/W wherein A is the minimum local cross-sectional area of the channel and W is the minimum local wetting perimeter of the channel, by smoothly widening the channel at its inlet such that:
