Abstract: A bed scale system includes at least one sensor frame having structure for generating a weight signal of a curved object such as a supporting wheel on a hospital bed or the like. The sensor frame includes a pair of spaced sidewalls defining a receiving area for the curved object, a bottom surface connected between the spaced sidewalls, and a deflection tab cooperable with the bottom surface. The deflection tab is deflected relative to the spaced sidewalls upon an application of weight to the sidewalls. A strain gauge is secured to the deflection tab and outputs a weight signal corresponding to the weight of the curved object according to a deflection amount of the deflection tab. The economical system provides patient weight without requiring removal of the patient from bed.

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.
