Personal warming systems and apparatuses for use in hospitals and other settings, and associated methods of manufacture and use
First Claim
1. A method for controlling activation of an alarm associated with a patient warming device, the method comprising:
- receiving a temperature selection from an operator of the patient warming device, the temperature selection corresponding to a selected temperature of the patient warming device;
determining if a temperature of the patient warming device at a first time is greater than the selected temperature;
if the temperature of the patient warming device at the first time is greater than the selected temperature, start measuring an elapsed time;
when the elapsed time is greater than a preset period of time, determining if a temperature of the patient warming device at a second time is greater than the selected temperature; and
if the temperature of the patient warming device at the second time is greater than the selected temperature, activating the alarm.

Abstract
Personal warming systems and apparatuses for use in hospitals and other settings. In one embodiment, a heating mattress or pad for warming a patient during a hospital procedure can include a heating element positioned between a first foam portion and a second foam portion. The heating element and the foam portions can be at least partially enclosed in a fluid-resistant cover. The heating element can be operably connected to a control unit that allows an operator to select between a plurality of temperature options for the heating pad. In another embodiment, the heating pad can include one or more radiolucent, or at least generally radiolucent, features that will not appreciably obscure x-ray images taken of a patient positioned on the heating pad. In one aspect of this embodiment, the radiolucent features can include one or more of a carbon-based heating element, an optical temperature sensing device, and/or a thermally responsive state-changing device.

10. A method for controlling activation of an alarm associated with a patient warming device, the method comprising:
-
receiving a temperature selection from an operator of the patient warming device; determining if a temperature of the patient warming device is greater than a threshold temperature, wherein the threshold temperature exceeds the selected temperature by a predetermined margin; if the temperature of the patient warming device is greater than the threshold temperature, delaying activation of an alarm for a predetermined period of time; at the end of the predetermined period of time, determining if the temperature of the patient warming device is greater than the threshold temperature; and if the temperature of the patient warming device is greater than the threshold temperature after the predetermined period of time, activating the alarm. - View Dependent Claims (11, 12, 13)

14. A control unit for use with a patient warming device, wherein the control unit is configured to control power to the patient warming device by a method comprising:
-
receiving a temperature selection from an operator of the patient warming device, the temperature selection corresponding to a selected temperature of the patient warming device; receiving from the patient warming device, at a first time, a first operating temperature of the patient warming device; if the first operating temperature is less than the selected temperature, providing power to the patient warming device; if the first operating temperature is greater than the selected temperature, reducing power to the patient warming device; receiving from the patient warming device, at a second time, a second operating temperature of the patient warming device; if the second operating temperature is less than the selected temperature, providing power to the patient warming device; if the second operating temperature is greater than the selected temperature, determining if an interval of time from the first time to the second time is greater than a predetermined period of time; and if the interval of time from the first time to the second time is greater than the predetermined period of time, activating a warning indicator. - View Dependent Claims (15, 16, 17, 18, 19, 20)
