摘要:
A person support apparatus includes a first transceiver adapted to wirelessly communicate with a second transceiver of a headwall interface that is positioned off of the person support apparatus. A communication link is automatically established between the first and second transceivers without requiring a user of the person support apparatus to activate a designated control and without requiring the user to identify the headwall interface. The first transceiver includes a unique identifier assigned to the headwall interface in its messages to the headwall interface. The first transceiver may also automatically transmit a disconnect signal to the headwall interface indicating the termination of the communication link is not accidental. The disconnect signal is sent based on one or more of the following: (1) a brake being off, (2) an A/C power cord being unplugged; and/or (3) a signal strength between the transceivers decreasing.
摘要:
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.
摘要:
A sensing system for a patient support, such as a bed, cot, stretcher, or the like, provides data about the patient and/or the patient support itself. The sensing system may include a flexible sheet that houses a sensor array that detects interface pressures between the patient and the support surface on the patient support. A user interface allows a caregiver to control operational parameters of the sensor array, including alarms. A color coded map may be displayed on the user interface highlighting the patient's currently experienced interface pressures. A control system coupled to the sensor array may map the sensor outputs to the body of the patient in order to correlate the interface pressures to specific parts of the patient's body. Shear pressure may, in some embodiments, also be detected by the sensor sheet.
