Brain cooling apparatus and brain cooling device suitable thereto

摘要

A brain cooling apparatus is provided that can circulate a fluid between a containing unit of a brain cooling device and the brain cooling apparatus while maintaining an appropriate pressure of the fluid in the containing unit, and a brain cooling device suitable thereto also is provided. A control device circulates a physiological saline solution between a storage tank and a cuff by driving a first pump in a direction in which the physiological saline solution flows toward the cuff, and driving a second pump in a direction in which the physiological saline solution flows toward the storage tank. In this state, the control device adjusts the rotation speed of at least the second pump, so that the pressure of the physiological saline solution in the cuff becomes a preset target pressure.

主权项

1. A brain cooling apparatus adapted for a brain cooling device, the brain cooling device having a containing unit that can be expanded by the fluid injected therein and closely contact at least a part of an area from an oral cavity to a stomach of a living body, an injection unit that can inject fluid from outside the body into the containing unit, and an ejection unit that can eject the fluid inside the containing unit to outside the body, the brain cooling apparatus comprising:
an injection side connection unit that can be connected with the injection unit; an ejection side connection unit that can be connected with the ejection unit; a storage unit that stores the fluid; a supply channel that connects the storage unit and the injection side connection unit; a collection channel that connects the storage unit and the ejection side connection unit; a first pump that is disposed on the supply channel to cause the fluid to flow along the supply channel; a second pump that is disposed on the collection channel to cause the fluid to flow along the collection channel; and a control unit that controls driving of the first pump and the second pump, wherein the control unit adjusts a driving speed of at least the second pump, so that a pressure in the supply channel or the collection channel becomes a preset target pressure in a state of driving the first pump such that the fluid flows in a direction from the storage unit to the injection side connection unit and driving the second pump such that the fluid flows in a direction from the ejection side connection unit to the storage unit, and the control unit increases the driving speed of the second pump when the pressure in the supply channel or the collection channel is higher than the target pressure.
