Abstract
The present invention relates to a blanket for use with forced air convection systems, wherein the blanket includes multiple inlet ports. By providing a blanket with multiple inlets, the user has the choice of positioning the air supply or blower unit and the supply hose on either side of the patient. In addition, in a preferred embodiment, the inlet ports are resealable, thus allowing the user to switch inlets during use.
Claims6
A method of warming a patient's body, comprising the steps of:
- (a) providing an inflatable blanket for a patient's body, said inflatable blanket having a head end portion for positioning toward a patient's head, said blanket having at least two inlet ports being positioned about said head end portion of said blanket so that, in use, one said inlet port is positioned on one side of a patient's head and another of said inlet ports is positioned on another side of said patient's head, said blanket permitting warm air to escape from said blanket toward the patient's body;
- (b) positioning said blanket with respect to said patient's body so as to permit warm air to escape from said blanket toward the patient's body and thereby warm the patient's body, wherein the head end portion of said blanket is positioned toward the patient's head and one said inlet is positioned on one side of the patient's head and another of said inlet ports is positioned on another side of said patient's head;
- and
- (c) introducing warm air into at least one of said inlet ports so as to inflate said blanket with warm air and force said warm air through said blanket toward the patient's body, thereby warming the patient's body.
