Abstract: A device for use in surgical procedures formed of a concertina cartridge (1) of a resilient material. The cartridge (1) has a nozzle (5), the throat of which is designed to receive by snap-click action, a projection (9) formed internally of the chamber (1), to hold the cartridge in a collapsed, but resiliently releasable, state as it is compressed to that state under concertina action. The device has applicability to surgical procedures such as blood collection, drug infusion, and balloon catheter inflation while eliminating the dangers of bacterial infection always present when performing such procedures using devices and systems of the prior art.
