Flexible container with a preformed fluid channel and infusion pump device using such a container
First Claim
1. A flexible container for storing a liquid medicament and use with a conduit system, the flexible container comprising:
- a wall comprising two sheets of flexible material sealed together such that a storage volume intended to contain the liquid medicament is defined; and
an access opening, which provides a fluid connection to the conduit system in fluid connection with the storage volume via a fluid channel arranged between the storage volume and the access opening, wherein the fluid channel is formed by a cavity arranged in at least one of the two sheets such that the cavity is located between an oblong corrugation or groove formed in at least one of the two sheets; and
elements for positioning and/or fixating the flexible container in a connection element of an infusion pump device, wherein the connection element comprises two clamp parts adapted to positively and/or non-positively lock the flexible container, and to fluidly connect the access opening to the conduit system, and at least one clamp part further comprises resilient elements directed towards the opposite clamp part of the connection element, the resilient elements comprising a pad with a preformed oblong groove, corresponding to the outer shape of the fluid channel.

13. A flexible container for storing a liquid medicament and connectable to a conduit system of a connection element having two or more clamp parts arranged with two or more positioning bolts, the flexible container comprising:
-
a wall comprising two sheets of flexible material sealed together in a sealed area such that a storage volume intended to contain the liquid medicament is defined thereby; an access opening, which provides a fluid connection directly with the conduit system of the connection element, in fluid connection with the storage volume via a fluid channel arranged between the storage volume and the access opening, wherein the fluid channel is formed by a cavity arranged in at least one of the two sheets such that the cavity is located between an oblong corrugation or groove formed in at least one of the two sheets; and two or more holes arranged in the sealed area which interact with the two or more positioning bolts arranged on the two or more clamp parts to lock the flexible container to the connection element such that the access opening of the flexible container remains fluidly connected to the conduit system of the connection element; and at least one of the two or more clamp parts further comprises resilient elements directed towards the opposite clamp part of the connection element, the resilient elements comprising a pad with a preformed oblong groove, corresponding to the outer shape of the fluid channel. - View Dependent Claims (15)
