Abstract
A method and system for infusing medical liquid with gasses, the system comprising a gas source, a vacuum pump, a temperature-controlled container including a fluid reservoir coupled to the gas source and the vacuum pump, a heating and cooling system, and a sonicator, and a controller configured to de-gas a liquid in the fluid reservoir by activating the vacuum pump, re-gas the liquid in the fluid reservoir by releasing gas from the gas source to the fluid reservoir via a first fluid line, and deliver the re-gassed liquid from the fluid reservoir to a catheter via a second fluid line.
Claims19
A system for infusing medical liquid with gasses, the system comprising:
- a gas source;
- a vacuum pump;
- a temperature-controlled container including a fluid reservoir coupled to the gas source and the vacuum pump, a heating and cooling system, and a sonicator;
- and
- a controller configured to:
- de-gas a non-heme liquid in the fluid reservoir by heating the non-heme liquid until it reaches a given temperature and activating the vacuum pump therewith degassing the heated non-heme liquid;
- re-gas the de-gassed non-heme liquid in the fluid reservoir by cooling the non-heme liquid until the liquid reaches a given cooling temperature, releasing gas from the gas source to the fluid reservoir via a first fluid line therewith increasing pressure of the cooled non-heme liquid, and exposing the non-heme liquid to the gas at the increased pressure for a period of time for the gas to saturate the non-heme liquid;
- and
- deliver the re-gassed non-heme liquid from the fluid reservoir to a catheter via a second fluid line.
Non-transitory computer readable media comprising program code that when executed by a programmable processor causes execution of a method for infusing medical liquid with gasses, the computer readable media comprising:
- computer program code for de-gassing a non-heme liquid in a fluid reservoir by heating the non-heme liquid until it reaches a given temperature and activating the vacuum pump therewith degassing the heated non-heme liquid, and is comprised in a temperature-controlled container that includes a heating and cooling system and a sonicator;
- computer program code for re-gassing the de-gassed non-heme liquid in the fluid reservoir by cooling the non-heme liquid until the liquid reaches a given cooling temperature, releasing gas from the gas source to the fluid reservoir via a first fluid line therewith increasing pressure of the cooled non-heme liquid, and exposing the non-heme liquid to the gas at the increased pressure for a period of time for the gas to saturate the non-heme liquid;
- and
- computer program code for delivering the re-gassed non-heme liquid from the fluid reservoir to a catheter via a second fluid line.
