Abstract
A device for providing buoyancy comprising; —a bladder capable of being inflated; —a vessel containing fluid for inflating the bladder; and —one or more valves for controlling the passage of fluid between the bladder and the vessel; wherein one or more of the valves are capable of being opened to permit the passage of fluid from the vessel to the bladder in response to at least one of exposure of the device to a pre-determined pressure level and detection of blood oxygen concentration below a pre-determine threshold in an individual using the device.
Claims18
A device for providing buoyancy comprising:
- a bladder capable of being inflated;
- a vessel containing fluid for inflating the bladder;
- one or more valves for controlling the passage of fluid between the bladder and the vessel, wherein the one or more valves is capable of being opened to permit the passage of fluid from the vessel to the bladder in response to at least one of exposure of the device to a pre-determined pressure level and detection of a blood oxygen concentration below a pre-determined threshold in an individual using the device;
- an actuator capable of being activated to open at least one of the one or more valves upon being exposed to the pre-determined pressure level;
- and
- an oxymeter capable of causing at least one of the one or more valves to open upon detecting the blood oxygen concentration below the pre-determined threshold in the blood of the individual,
- wherein the actuator is adjustable to alter the pressure level at which activation occurs and the oxymeter is adjustable to alter the pre-determined oxygen concentration at which it causes the at least one of the one or more valves to open.
A method for providing buoyancy comprising:
- providing a bladder for inflating;
- providing a vessel containing fluid for inflating the bladder;
- controlling the passage of fluid between the bladder and the vessel with one or more valves;
- opening at least one of the one or more valves to permit the passage of fluid from the vessel to the bladder in response to at least one of exposing the device to a pre-determined pressure level and detecting a blood oxygen concentration below a pre-determined threshold in an individual;
- providing an actuator capable of being activated to open the at least one of the one or more valves upon being exposed to the pre-determined pressure level;
- providing an oxymeter capable of causing the at least one of the one or more valves to open upon detecting the blood oxygen concentration below the pre-determined threshold in the blood of the individual;
- and
- adjusting the actuator to alter the pressure level at which the activation occurs and the oxymeter to alter the pre-determined oxygen concentration at which it causes the at least one of the one or more valves to open.
