Continuous infusion device

A device for continuous infusions comprising:

• a housing having a base, the base of the housing configured to be set down on a planar horizontal resting surface during use,
• an infusion appliance seat disposed in the housing for receiving an infusion appliance with at least one container that can be pressed empty by a ram, the infusion appliance seat extending along a main axis of extent from a ram-side end to an outlet-side end,
• an actuator for automatically emptying the infusion appliance,
• a drive for moving a ram abutment/actuation element of the actuator, and
• a control arrangement by which a speed of advance of the actuator is adjustable,
• wherein the main axis of extent of the infusion appliance seat has a predetermined relief angle in relation to a support plane of the housing, the support plane being coplanar with the base of the housing,
• wherein the infusion appliance seat is disposed above the base of the housing during use,
• wherein the outlet-side end is arranged above the ram-side end of the infusion appliance seat with respect to the support plane,
• wherein the infusion appliance comprises an infusion syringe which is configured in terms of size and geometry to fit into the infusion appliance seat and has an eccentrically arranged syringe outlet with respect to the main axis of extent,
• wherein the infusion syringe is connected to an infusion line, on the end of which is provided a hydrophobic membrane which serves for venting and is permeable to air but provides a seal against liquid, and
• wherein the infusion syringe seated in the infusion appliance seat is displaceable by the closing movement of the housing cover or the displacement device towards the ram abutment/actuation element until the hydrophobic membrane is acted upon by the infusion liquid held in the container via the infusion line.

• wherein the infusion appliance seat is disposed above the base of the housing during use,
• wherein the outlet-side end is arranged above the ram-side end of the infusion appliance seat with respect to the support plane,
• wherein the infusion appliance comprises an infusion syringe which is configured in terms of size and geometry to fit into the infusion appliance seat and has an eccentrically arranged syringe outlet with respect to the main axis of extent,
• wherein the infusion syringe is connected to an infusion line, on the end of which is provided a first hydrophobic membrane which serves for venting and is permeable to air but provides a seal against liquid,
• further comprising a second hydrophobic membrane, which above a predetermined threshold pressure is permeable with respect to the infusion liquid, arranged upstream of the hydrophobic membrane, and
• further comprising a locking arrangement to fix the infusion appliance seat in relation to the housing, wherein the locking arrangement is configured to be activated by a motion resistance which acts on the infusion appliance seat and which is generated by the liquid pressure building up between the hydrophobic membrane and the syringe plunger during the displacement of the infusion appliance against the ram abutment/actuation element.

• an infusion appliance seat disposed in the housing for receiving an infusion appliance with at least one container that can be pressed empty by a ram, the infusion appliance seat extending along a main axis, and configured to support the infusion appliance from a ram-side end to an outlet-side end of the infusion appliance,
• an actuator for automatically emptying the infusion appliance,
• a drive for moving a ram abutment/actuation element of the actuator, and
• a control arrangement by which a speed of advance of the actuator is adjustable,
• wherein the main axis of extent of the infusion appliance seat has a predetermined relief angle in relation to a support plane of the housing, so as to cause a main axis of extent of the infusion appliance to have the same predetermined relief angle as the infusion appliance seat in relation to the support plane,
• wherein the outlet-side end is arranged above the ram-side end of the infusion appliance seat,
• wherein the infusion appliance comprises an infusion syringe which is configured in terms of size and geometry to fit into the infusion appliance seat and has an eccentrically arranged syringe outlet with respect to the main axis of extent, and
• wherein the infusion syringe is connected to an infusion line, on the end of which is provided a hydrophobic membrane which serves for venting and is permeable to air but provides a seal against liquid.
