  • Patent number: 5830195
    Abstract: A medical coupling has male and female members (1, 2) which push fit together, and a screw cap (7) which secures the members against separation. To prevent unintentional release of the cap, locking means, such as a ratchet and pawl mechanism, are provided between the cap and female member. Au outer shell (25) can enclose the cap for providing an enclosure around the fluid connection to deter bacterial contamination. Alternatively a separate capsule can enclose the coupling for this purpose. The two members and cap are connectable by holding gripping portions which are located remotely from the parts forming the fluid connection to reduce risk of contamination. A valve system is associated with the female member for closing a flexible tube connected to this member and to displace liquid to fill the space left in this member when the male member is disconnected from it.

  • Patent number: 5795340
    Abstract: The invention relates to a microcatheter set with a minimized dead space which has a medicine application and flushing device especially suitable for intensive paediatric-neonatologial medicine. It makes it possible not only to apply infusion therapy via a microcatheter inserted into a large body vein but also to administer drugs repeatedly without any danger via the medicine application and flushing device integrated within the set, even with highly pharmacologically effective additives to the general infusion solution, and/or to do away with partial and total catheter shut-offs. This thus excludes additional stress on and risk for the patient by the repeated application of peripheral infusions or the use of surgically inserted double-lumen central catheters for the intravenous administration of drugs.
