title = "Soluble gas tight capsules for use in surgical quality testing",
abstract = "During many surgical procedures such as gastrointestinal or vascular surgery it is necessary to excise and reconnect bodily conduits. Failed connections can have extremely serious consequences and a method to help surgeons determine the integrity of connections has been proposed. This involves the detection of trace gas breaching an anastomosis. A key feature of this is establishing a method to place a controlled volume of gas into the conduit. A soluble capsule method is presented here. The requirements were that the capsule must be safe, a volume of 0.5 - 1.0ml of gas at 2 Bar pressure should be contained, that the filling gas can be varied to suit the clinical application and that the capsules have a shelf life of at least 5 days without showing loss of gas. A device and procedure were developed to meet these criteria. This consists of modified oral pharmaceutical capsules and a capsule filling mechanism contained in a vacuum chamber. Sealing the capsules has been achieved via an alcohol / water mix coupled to capilliary action. Results show performance which meets the design specification and the capsules have shown themselves effective in tests using phantom scenarios.",
