Braunüle This is a sealed package containing a Braunüle. The clear plastic packaging reveals an orange paper tray with black writing: “B. Braun Melsungen. Braunula, sterile, size 1, medium disposable”, “Luer”, and “Made in Germany”. The tray has two fenestrations housing the peripheral catheter with an integrated injection port. In a smaller clear plastic package, there is the clamp-style catheter connector. The Braunula, the first cannula invented in Germany, is composed of a plastic cannula over a needle, which is removed after insertion, leaving the flexible cannula in place. The insertion technique is represented on the back of the paper tray. Inside, a small tag of white paper has printed the manufacturer logo and the number 5463. 1925-1975
