A medical connector for delivering a liquid at a high flow rate to a patient. The connector includes 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 is configured for connecting to tubing through which the liquid in the container can be administered to a patient. 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 the second open end has an annular elastomeric member that attaches to the spike via compressive pressure applied by the annular elastomeric member.

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, andwherein the second open end has an annular elastomeric member that attaches to the spike via compressive pressure applied by the annular elastomeric member. 2. The connector of claim 1, wherein the source of pressurized gas includes a compressor from which the gas pressurized therein is provided to the gas inlet passage so as to pressurize the container and thus forcibly expel the liquid therein through the liquid outlet passage. 3. The connector of claim 1, wherein the source of pressurized gas includes a cartridge from which the gas pressurized therein is provided to the gas inlet passage so as to pressurize the container and thus forcibly expel the liquid therein through the liquid outlet passage. 4. The connector of claim 1, wherein the source of pressurized gas includes a refill port through which to refill the source of pressurized gas. 5. The medical connector of claim 1, wherein the shield has a body that is collapsible between the first closed end and the second open end. 6. The medical connector of claim 1, wherein the second open end is sterilized with a sterilizing swab. 7. A system for dispensing a medical liquid, the system comprising: a source of gas; anda connector for connection to a container of the medical liquid, the connector having a gas inlet passage that is connectible to the source of gas, a spike configured for piercing a stopper of the container, and a liquid outlet passage in fluid communication with the spike;such that a gas from the source of gas flows into the gas inlet passage to pressurize the container and thus forcibly expels the medical liquid therein through the liquid outlet passage and into a tubing connectible thereto 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, andwherein the second open end has an annular elastomeric member that attaches to the spike via compressive pressure applied by the annular elastomeric member. 8. The system of claim 7, wherein the source of gas includes a compressor from which the gas pressurized therein is provided to the gas inlet passage so as to pressurize the container and thus forcibly expel the medical liquid therein through the liquid outlet passage. 9. The system of claim 7, wherein the source of gas includes a cartridge from which the gas pressurized therein is provided to the gas inlet passage so as to pressurize the container and thus forcibly expel the medical liquid therein through the liquid outlet passage. 10. The system of claim 7, wherein the source of gas includes a refill port through which to refill the source of gas. 11. The system of claim 7, wherein the shield has a body that is collapsible between the first closed end and the second open end. 12. The system of claim 7, wherein the second open end is sterilized with a sterilizing swab. 13. A system for dispensing a liquid, the system comprising: a source of gas;a connector having a gas inlet passage, a spike, and a liquid outlet passage; anda container connected to the connector, with the gas inlet passage being connected to the source of gas and the liquid outlet passage being connectible to a tubing,such that a gas from the source of gas flows into the gas inlet passage to pressurize the container and thus forcibly expels the liquid therein through the liquid outlet passage and into the tubing 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 a stopper of the container, andwherein the second open end has an annular elastomeric member that attaches to the spike via compressive pressure applied by the annular elastomeric member. 14. The system of claim 13, wherein the source of gas includes a compressor from which the gas pressurized therein is provided to the gas inlet passage so as to pressurize the container and thus forcibly expel the liquid therein through the liquid outlet passage. 15. The system of claim 13, wherein the source of gas includes a cartridge from which the gas pressurized therein is provided to the gas inlet passage so as to pressurize the container and thus forcibly expel the liquid therein through the liquid outlet passage. 16. The system of claim 13, wherein the source of gas includes a refill port through which to refill the source of gas. 17. The system of claim 13, wherein the shield has a body that is collapsible between the first closed end and the second open end.
