Safety extraction system for medical liquid glass or plastic container, has safety spike with thorns made of metal or plastic, where configuration of thorns takes over key lock function, and thorns and channels are conically designed

摘要

The system has a 2k-safety stopper (2) with special guiding channels, and a safety spike with hollow pins that are appropriately suitable into the guiding channels. The hollow pins has a contra-click (10) to make a fixed connection between the safety stopper and the safety spike. The safety spike is provided in a closure of a container, and is positively driven via the safety stopper. The safety spike has thorns that are made of metal or plastic. A configuration of the thorns takes over a key lock function, where the thorns and the guiding channels are conically designed. An independent claim is also included for an infusion system comprising a safety spike, which replaces thorns of an infusion cutlery.
