Abstract

This disclosure generally relates to support apparatuses. More specifically, but not exclusively, the disclosure relates to support surface systems for person support apparatuses. Inflation of the support surfaces may be accomplished by a fairly sophisticated control system having sensors and one or more microprocessors. The sensors measure air pressure within the one or more air bladders of the support surface. The one or more microprocessors control other components of the control system, based on the pressure sensed by the sensors. However, inflation techniques used ion some existing control systems might result in t bottoming out of the support surfaces when the support surfaces are accommodated by heavy weight patients.

Support Surface System for a Person Support Apparatus

This disclosure generally relates a person support apparatuses. More specifically, but not exclusively, the disclosure relates to support surface systems for person support apparatuses.

Generally, a healthcare facility is equipped with a number of person support apparatuses. These person support apparatuses are required to support a person (patient) under medical assistance. The person support apparatus, generally, includes a frame, a deck, and a support surface. The deck is coupled to the frame, which, in turn is attached to the support surface. The person support apparatus is adapted and structured to provide support to a patient’s body. The support surface of the person support apparatus is equipped with one or more inflatable air bladders. Some support surfaces having air bladders are used in healthcare facilities, to support patients requiring long term care. The healthcare facilities use a variety of different support surfaces to accommodate patients having different medical needs. Some patients benefit from being supported on alternating pressure support surfaces or rotation therapy support surfaces. Other patients may not need to be supported on these types of support surfaces having dynamic therapies, but rather, so-called static air support surfaces, which operate to provide a relatively low interface pressure, may be suitable for such patients. To address these various support surface requirements, there may be a number of support surfaces, each with its own particularized therapeutic function, or having control units allowing users to program or select different modes of operation. However, the support surfaces that allow users with selectable functionality, introduce the possibility of inadvertently configuring the mattress (support surface) with a less than optimal type of therapy or operation among the plurality of the available therapies.

Inflation of the support surfaces may be accomplished by a fairly sophisticated control system having sensors and one or more microprocessors. The sensors measure air pressure within the one or more air bladders of the support surface. The one or more microprocessors control other components of the control system, based on the pressure sensed by the sensors. However, inflation techniques used in some existing control systems might result in bottoming out of the support surfaces when the support surfaces are accommodated by heavy weight patients.

This disclosure generally relates to a support surface system for a person support apparatus. The support surface system includes a support surface, an air supply, at least one pressure sensor, at least one weight sensor, and a controller. The support surface is equipped with a bladder assembly. The bladder assembly is connected to the air supply, which is configured to inflate and deflate the bladder assembly of the support surface. The at least one pressure sensor is coupled to the support surf...
