摘要： An apparatus for dispensing a gas contained in a sealed ampule, typically a radioactive gas dissolved in a saline solution. A housing with a cavity for receiving the ampule, the housing having a lead shield surrounded by a steel sleeve, and a cap for closing the cavity in the shield. First and second flow paths are provided in the housing from the exterior of the housing to a seat which engages the ampule output line. A syringe is attached on the outside of the housing and connects with the first flow path. A hollow needle is positioned in the second flow path with one end entering the ampule outlet line for breaking the ampule seal. A valve on the outer end of the needle is normally closed so that when the needle breaks the seal, liquid from the syringe is drawn into the ampule with the gas dissolving in the liquid. Then the gas-liquid solution is withdrawn through the needle and valve.
