Abstract
A medical gas condition system for supplying a liquid hydration fluid to a hydrator before or during an ongoing medical procedure by coupling the flow of liquid hydration fluid into the hydrator to either the absence of flow of medical insufflation gas into the hydrator or to a condition where the liquid hydration fluid can be absorbed by a hydrator instead of being forced through the hydrator in liquid form.
Claims21
A medical gas conditioning system comprising;
- a hydrator;
- a source of medical insufflation gas;
- a sensor for detecting a flow or an absence of a flow of the medical insufflation gas into the hydrator;
- a source of liquid hydration fluid;
- and
- a controller responsive to the sensor, said controller terminating the delivery of the liquid hydration fluid to the hydrator during an absence of the flow of a medical insufflation gas into the hydrator or during a critical flow condition.
A medical gas hydration system comprising:
- a hydrator for hydrating a medical gas;
- a sensor for determining a flow of a medical insufflation gas flowing into the hydrator;
- a controller for terminating the flow of medical insufflation gas if the hydration fluid flows through the hydrator before the hydrator can absorb the hydration fluid;
- and
- a device for delivering a hydration fluid to the hydrator during a period when there is an absence of insufflation gas flowing into the hydrator or during a period when the flow of insufflation gas is insufficient to force the hydration fluid through the hydrator before the hydrator can absorb the hydration fluid.
The method of automatically hydrating an insufflation gas during a medical procedure without forcing hydration fluid through a hydrator comprising:
- intermittently supplying a medical insufflation gas to the hydrator;
- monitoring a flow of medical insufflation gas to the hydrator;
- and
- supplying a hydration fluid to the hydrator during a time period where there is an absence of the flow medical insufflation into the hydrator to thereby rehydrate the hydrator without accidentally forcing hydration fluid through the hydrator.
The method of automatically hydrating an insufflation gas during a medical procedure without forcing liquid hydration fluid through a trocar comprising:
- supplying a medical insufflation gas to the hydrator;
- monitoring a flow of medical insufflation gas to the hydrator;
- and
- supplying a liquid hydration fluid to the hydrator during the supplying of the medical gas to the hydrator by supplying the liquid hydration fluid at a flow rate such that the liquid hydration fluid can be absorbed the hydrator without accidentally forcing the liquid hydration fluid through the trocar.
The method of claim 21 wherein the flow rate where liquid hydration fluid can be absorbed by the hydrator is determined by visually observing the flow of insufflation gas flowing through the trocar to detect a condition where the liquid hydration fluid is not visually present in the medical insufflation gas.
