Abstract
A brain cooling apparatus includes a tube body 2 which can maintain an airway in the respiratory tract of a living body; a pharyngeal cuff 5 which is provided in the peripheral part of this tube body 2 and can store a cooled fluid; and an injection and discharge portion 6 which can inject and discharge a fluid into and from this pharyngeal cuff 5, in which the pharyngeal cuff 5 is flexible enough to inflate and deflate when a fluid is injected and discharged, and when a fluid is injected in a state where an airway in the respiratory tract of a living body is maintained by the tube body 2, the inflated pharyngeal cuff adheres closely to the pharyngeal part T of the living body.
Claims9
A brain cooling apparatus, comprising:
- a tube-shaped member which is orally or nasally inserted so that an airway is maintained in the respiratory tract of living body;
- a storage portion which is attached to the peripheral part of the tube-shaped member and stores a cooled fluid;
- an injection and discharge portion which injects and discharges a fluid into and from the storage portion;
- and
- a cuff attached to the peripheral part of a front end of the tube-shaped member,
- wherein the storage portion and the cuff are flexible enough to inflate and deflate when a fluid is injected and discharged, and are such that when a fluid is injected, the cuff is configured to adhere closely to a peripheral part of an opening part of a trachea such that an airway in the respiratory tract of living body is maintained by the tube-shaped member, and the inflated storage portion is configured to adhere closely to the pharyngeal part of the living body;
- wherein the cuff is configured to inflate by storing a fluid that is injected from the injection and discharge portion;
- and
- wherein the storage portion is connected to the cuff so that the storage portion receives a fluid which is injected into the cuff, and extends from the cuff toward the side of the basic-end part of the tube-shaped member, along the axial direction of the tube-shaped member.
