Luer lock connector with grooves
Connector systems for a fluid container for pharmaceutical solutions are disclosed. The systems include an outer part adapted for insertion into a fluid conducting system and an inner part arranged in said outer part. The outer part includes a tamper-evident closure connected thereto at a predetermined breaking point that can be manually removed. An external side of the inner part abuts an internal side of the outer part. A closure element attached to the inner part prevents a flow of fluid through the inner part. The inner part and the outer part having provided thereon at least one fluid conducting element, such as a furrow, a flute, a depression or a groove. Medical supply systems comprising a bag, such as a dialysis bag, having such systems are also described.
1. A connector system for a fluid container for pharmaceutical solutions, comprising:
an outer part having an inner circumferential surface and an outer circumferential surface, the outer part adapted to be inserted into a fluid conducting system; and
an inner part having an outer circumferential surface and an inner circumferential surface, the inner part arranged in said outer part and materially separate therefrom;
wherein the outer part has provided thereon a tamper-evident closure, which is connected thereto at a predetermined breaking point and which can be torn off by manual force, wherein the outer circumferential surface of the inner part further abuts, at least sectionwise, with the inner circumferential surface of the outer part, wherein, in addition to the tamper-evident closure, a closure element attached to the inner part prevents a flow of fluid through the inner part, and wherein the inner part and the outer part have provided therein at least one fluid conducting element wherein the at least one fluid conducting element is formed within at least one of the outer circumferential surface of the inner part or the inner circumferential surface of the outer part as at least one of a furrow, a flute, a depression, or a groove, wherein the at least one fluid conducting element is formed between the outer circumferential surface of the inner part and the inner circumferential surface of the outer part, wherein the at least one fluid conducting element does not perforate through the inner part from the inner circumferential surface of the inner part to the outer circumferential surface of the inner part, and wherein the at least one fluid conducting element does not perforate through the outer part from the inner circumferential surface of the outer part to the outer circumferential surface of the outer part.
2. The connector system according to claim 1 , wherein a plurality of fluid conducting elements is provided.
3. The connector system according to claim 2 , wherein the plurality of fluid conducting elements are uniformly distributed over the outer circumferential surface of the inner part and extend straight or in a curved shape.
4. The connector system according to claim 1 , wherein the inner circumferential surface of the outer part is cylindrical.
5. The connector system according to claim 1 , wherein the outer part is configured as a luer cone on an external side thereof.
6. The connector system according to claim 1 , wherein, on a side of the outer part facing the tamper-evident closure, a luer lock external thread or a luer slip extension is provided.
7. The connector system according to claim 1 , wherein the tamper-evident closure is configured as a wing-shaped handle.
8. A medical supply system, comprising a fluid bag having the connector system according to claim 1 integrated or inserted therein.
9. The system of claim 8 , wherein the fluid bag is a dialysis bag.
10. The connector system according to claim 1 , wherein the fluid conducting system is a hose or a bag spout.
11. The connector system according to claim 1 , wherein the outer circumferential surface of the inner part is cylindrical.
12. The connector system according to claim 1 , wherein the inner part is configured as a luer cone on an internal side thereof.
13. The connector system according to claim 1 , wherein the closure element is configured as a frangible cross member connected to a predetermined breaking point.
14. The connector system according to claim 13 , wherein the frangible cross member is connected to the inner part at an inner part end facing away from the tamper-evident closure.
