1. A pneumatic system, comprising:
- a pneumatic adaptor, comprising;
a nipple comprising a shaft including a nipple first end and a nipple second end, the nipple first end configured to mate with a gas source;
a connector including a connector first end and a connector second end, the connector first end coupled to the nipple second end and the connector second end configured to mate exclusively with a gas-specific medical tubing connector; and
a nut configured to couple the nipple to the gas source comprising;
a bore through which the shaft of the nipple passes; and
an aperture through which the first end of the nipple emerges; and
a first section of medical tubing comprising a first gas-specific medical tubing connector coupled to the second end of the connector on the pneumatic adaptor.

7. A method for injecting gas into a patient, comprising:
-
coupling a pneumatic adaptor to a specific gas source, the pneumatic adaptor comprising a first end configured to mate exclusively with the specific gas source; coupling a first section of medical tubing to a second end of the pneumatic adaptor, the second end comprising a connector specific to the gas from the gas source, and the first section of medical tubing being coupled to a gas reservoir; accessing the gas source such that gas flows through the pneumatic adaptor into the gas reservoir via the first section of medical tubing; uncoupling the first medical tubing connector from the pneumatic adaptor; coupling the first section of medical tubing to a syringe connector coupled to a syringe, the syringe comprising a syringe plunger, syringe barrel, and syringe nozzle; coupling a second section of medical tubing to the syringe nozzle and to the patient; actuating the syringe plunger to draw gas from the gas reservoir and into the syringe barrel; and applying positive pressure to the syringe plunger until gas is forced into the patient. - View Dependent Claims (8, 9, 10)

11. A carbon dioxide pneumatic adaptor, comprising:
-
a nipple, comprising; a shaft comprising a nipple first end and a nipple second end, the nipple first end configured to mate exclusively with a carbon dioxide gas source; a nipple central lumen running from the nipple first end to the nipple second end; a flange positioned on the shaft between the nipple first end and the nipple second end; a connector, comprising; a connector first end coupled to the nipple second end; a connector second end configured to mate exclusively with a gas-specific medical tubing connector; a connector central lumen running from the connector first end to the connector second end such that the nipple and connector are in fluid communication; and a nut coupled to the nipple, the nut configured to couple the nipple to a carbon dioxide gas source and the nut limits axial movement of the nipple by abutment with the flange positioned on the shaft of the nipple. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
