Claim Text:
1. A medical connector for delivering a liquid at a high flow rate to a patient, the connector comprising: a gas inlet passage that is configured for connecting to a source of pressurized gas; a spike configured for piercing a stopper of a container; and a liquid outlet passage in fluid communication with the spike, the liquid outlet passage configured for connecting to tubing through which the liquid in the container can be administered to a patient, wherein, when the connector is connected to the container and the gas inlet passage is connected to the source of pressurized gas, a gas from the source of pressurized gas flows into the gas inlet passage to pressurize the container and thus forcibly expels the liquid therein through the liquid outlet passage and the tubing and into the patient at a rate of flow corresponding to a level of a pressure developed within the container by the gas delivered thereto, wherein the spike has a shield having a first closed end and a second open end such that the first closed end is breakable by the spike when the spike is inserted through the stopper of the container, and wherein the second open end has an annular elastomeric member that attaches to the spike via compressive pressure applied by the annular elastomeric member.
