Title:
改良された医療機器の流れ止め境界領域
Document Type and Number:
Japanese Patent JP2004528117
Kind Code:
A
Abstract:
A fluid infusion pump includes a platen between an outer door and the pumping mechanism. The platen is located so that as the outer door of the pump is moved to the closed position, it moves the platen to position the fluid flow tube into occlusive contact with the pumping mechanism before the platen engages a flow stop formed integrally with the tube and releases the flow stop to permit fluid flow, thus avoiding a free flow condition. The door also includes a handle having a sear with a hook that engages the flow stop when the door is in the closed position. As the door is opened, the hook moves the flow stop to the occluded position before the platen is moved away from the tube thus preventing a free flow condition. The platen includes a flow stop release portion that is offset from the remainder of the platen that operatively engages a release tab on the flow stop to permit movement of the flow stop to the fluid flow configuration. The platen is mounted to the housing with a floating hinge and datum pins located on the face of the pumping mechanism precisely locate the platen into position with the pumping mechanism and thereby result in precise positioning of the fluid tube.
