Abstract
Disclosed is a cradle for an infusion pump unit. The cradle has a proximal side and a distal side, and the distal side has an infusion pump unit attachment structure for attaching an initially separate infusion pump unit. The cradle includes a cradle base, a flow channel for a liquid drug, and a pierceable septum. The pierceable septum covers an opening of the flow channel and seals the flow channel. An inner piercing core of the pierceable septum is movably mounted with respect to the cradle base.
Claims25
A cradle for use with an infusion pump, the cradle comprising:
- a proximal side and a distal side, the distal side having an infusion pump attachment structure configured for attaching an initially separate infusion pump;
- a cradle base;
- a flow channel for a liquid drug;
- and
- a pierceable septum covering an opening of the flow channel and sealing the flow channel, the pierceable septum having an inner piercing core that is movably mounted with respect to the cradle base, wherein the pierceable septum as a whole is movable in a lateral direction of the cradle base and/or tiltable with respect to a horizontal plane of the cradle base.
A cradle for use with an infusion pump having a transfer cannula, the cradle comprising:
- a proximal side and a distal side, the distal side having an infusion pump attachment structure configured for attaching an initially separate infusion pump;
- a cradle base;
- a flow channel for a liquid drug;
- and a pierceable septum covering an opening of the flow channel and sealing the flow channel, the pierceable septum having an inner piercing core that is movably mounted with respect to the cradle base, wherein the pierceable septum as a whole is movable in a lateral direction of the cradle base and/or tiltable with respect to a horizontal plane of the cradle base;
- a guide arranged on the distal side of the cradle and configured for providing a linear guiding path along a piercing axis (A) of the pierceable septum;
- wherein the guide surrounds the flow channel and the pierceable septum and the guide guides the flow channel and pierceable septum along the piercing axis (A);
- wherein the guide is movable along the piercing axis (A) toward the transfer cannula and wherein the guide has a complementary shape to the flow channel and/or the pierceable septum.
A cradle for use with an infusion pump, the cradle comprising:
- a proximal side and a distal side, the distal side having an infusion pump attachment structure configured for attaching an initially separate infusion pump;
- a cradle base;
- a flow channel for a liquid drug, the flow channel comprising a pivotable L-shaped arm;
- and a pierceable septum covering an opening of the flow channel and sealing the flow channel, the pierceable septum having an inner piercing core that is pivotably mounted with respect to the cradle base, wherein the pierceable septum as a whole is movable in a lateral direction of the cradle base and/or tiltable with respect to a horizontal plane of the cradle base.
A cradle for use with an infusion pump having a transfer cannula, the cradle comprising:
- a proximal side and a distal side, the distal side having an infusion pump attachment structure configured for attaching an initially separate infusion pump;
- a cradle base;
- a flow channel for a liquid drug;
- and a pierceable septum covering an opening of the flow channel and sealing the flow channel, the pierceable septum having an inner piercing core that is movably mounted with respect to the cradle base, wherein the pierceable septum as a whole is movable in a lateral direction of the cradle base and/or tiltable with respect to a horizontal plane of the cradle base;
- a guide arranged on the distal side of the cradle and configured for providing a linear guiding path along a piercing axis (A) of the pierceable septum;
- wherein the guide surrounds the flow channel and the pierceable septum and the guide guides the flow channel and pierceable septum along the piercing axis (A);
- wherein the guide is slidable along the piercing axis (A) toward the transfer cannula;
- and wherein the guide has a complementary shape to the flow channel and/or the pierceable septum.
