Abstract: Fluid control device (70) including a housing (31) with a syringe port (33) for receiving a syringe, a vial adapter port (36) with a vial adapter (86) for snap fit receiving a vial, and a drug administration port (34) for administering a liquid drug. The vial adapter is intended to be rotationally detached after a mixing procedure for discarding together with a spent vial. The fluid control device additionally includes a manually depressed actuator (74) for sealing pathways which may lead to leakage of liquid drug subsequent to vial adapter detachment, thereby facilitating their use for handling and administration of hazardous liquid drugs. The manually depressed actuator preferably precludes vial adapter detachment prior to actuation, thereby ensuring failsafe operation.

Abstract: An ophthalmic sizing device includes a sizing tube or set of such sizing tubes for use in determining a correct size of a bypass tube required in lacrimal surgery, each sizing tube having a flanged end at one end of a longitudinal length of tubing, the remaining end of the tubing distal to the flanged end having a series of ruled markings longitudinally along and towards the flange end. When used, a set of sizing tubes includes tubes having at least two relatively different absolute longitudinal lengths of tubing; and/or diameter flanges. The device can be in the form of a dilator having a sizing section. The use of such sizing devices allows the length of an ophthalmic bypass tube to be determined that leaves the tip of the bypass tube, when in situ, to protrude an optimally desired distance beyond the outer (lateral) nasal wall and into the nasal cavity of each particular patient, while remaining clear of the midline septum.

Abstract: A method and arrangement for destroying tunnels. A subterraneous, vertical shaft is excavated until a tunnel preventing depth. After liquid is introduced to the shaft, a shaft liner is penetrable by the introduced liquid when a tunnel is present in the vicinity of said shaft, due to the considerably larger pressure of the introduced liquid relative to the bearing capacity of soil interposed between the tunnel and shaft. The tunnel is then flooded and destroyed following passage of the liquid through the liner. A system for detecting and destroying tunnels in the proximity of a security-sensitive facility comprises a hollow member anchored to the upper soil surface adjoining each shaft, a sensor having a unique address mounted on a corresponding hollow member for generating an electrical output when the liquid level has been reduced more than a predetermined level, and a computer in data communication with each of the sensors.
