Connector for packings containing medical liquids, and corresponding packing for medical liquids
DC
First Claim
1. A connector for packings containing medical liquids, particularly infusion, transfusion or enteral bags, comprising:
- a connecting part that is an injection-molded component with a passage to accommodate a rod or a spike for filling or withdrawal of liquid, wherein the connecting part comprises,an elastically deformable pinching-off part, which re-assumes its original shape again after being pinched by a pinching device, and is designed as a tubular portion with a noncircular axial cross section that is different in two mutually perpendicular directions, anda base part that merges into the pinching-off part, wherein the base part widens to both sides and can be integrated in the packing, and wherein the pinching-off part comprises the same polymer as the base part; and
a closure part which can be fitted onto the connecting part and closes the passage in the connecting part.

Abstract
A connector for packings containing medical liquids, particularly infusion, transfusion or enteral bags, comprises a connecting part (1) for accommodating a spike for drawing out the liquid and comprises a closure part (3) that closes the passage (2) inside the connecting part (1). The connecting part (1) has an elastically deformable pinching off part (4) provided in the form of a tubular section with a non-circular cross-section. A base part (5), which widens on both sides is adjoined to said pinching off part (4) and can be integrated in the packing. During manufacturing, the packing is filled with liquid via the connecting part. After filling, the pinching off part is pressed together whereby preventing liquid from escaping. Afterwards, the closure part is placed onto the connecting part. The manufacturing of the packing is simplified by virtue of the fact that an additional tube for connecting the connector and packing is rendered unnecessary.
