Patent attributes
A patient support apparatus, such as a bed, cot, stretcher, or the like, uses the ability to communicate with a device via near field communication to determine that the device is physically proximate the support apparatus. The support apparatus uses this determination to associate itself with the device. In some instances, the associated device is a mattress positioned on the support apparatus; a footboard on the support apparatus; a medical device used with a patient supported on the support device; a nearby piece of furniture; another patient support apparatus; or an ID tag worn by a caregiver or patient, or attached to a piece of equipment. After the support apparatus and device are associated, they communicate information between each other using far field communication, which supports higher data transfer rates. Flux concentrators are added in some embodiments to extend and/or shape the range of near the field communication.
