Abstract

Relates to a person support surfaces that facilitate a push up in bed force to a patient. More specifically, but not exclusively, the disclosure relates to a shear reduction system for the person support surface, which facilitates shear reduction to the patient during push up in bed operation moving the patient back to the head of the bed.

Shear Reduction System for Person Support Surface

This disclosure generally relates to a person support surfaces that facilitate a push up in bed force to a patient. More specifically, but not exclusively, the disclosure relates to a shear reduction system for the person support surface, which facilitates shear reduction to the patient during push up in bed operation moving the patient back to the head of the bed.

Generally, a healthcare facility is equipped with a number of person support surfaces, each of which is adapted to support a person under medical assistance (patient). Several types of person support surfaces are known in the medical industry, In some, inflatable bladders are inflated or deflated, to raise or lower a foot section of the patient, when required. In so doing, a minimal amount of horizontal push may be applied to a back section of the patient. This could lead to a shear force between the back section of the patient and the topper member.  Therefore, a person support surface is desired to be equipped with a system that facilitates shear reduction to the patient, especially during push up in bed operations applied to the patient.

The disclosure generally relates to a shear reduction system for a person support surface. The person support surface includes a plurality of inflatable bladders, a topper member, and at least one inflatable bellow. An enclosed space is defined between the plurality of inflatable bladders and the topper member. The enclosed space defines an upper section and a lower section. The at least one inflatable bellow is disposed within the lower section of the enclosed space. The at least one bellow is capable of being inflated and deflated. The shear reduction system includes a plurality of inflatable vibratory bellows and a controlled inflation system. The plurality of inflatable vibratory bellows are disposed within the upper section of the enclosed space of the person support surface. The controlled inflation system includes an air supply, a control valve, and a controller. The air supply is fluidly connected to the plurality of inflatable vibratory bellows of the person support surface. The air supply is adapted to supply compressed air to the plurality of inflatable vibratory bellows. The control valve is fluidly disposed between the air supply and the plurality of inflatable vibratory bellows and is adapted to operate in one of an open state and a closed state. In the open state, the control valve allows the supply of compressed air from the air supply to the plurality of inflatable vibratory bellows, wherein in the closed state, the control valve restricts the supply of compressed air from the air supply to the plurality of inflatable vibratory bellows. The controller is electrically connected to each of the at least one inflatable bellow and the control valve. The controller is adapted to adjust the control valve in the open state when the at least one inflatable bellow is adjusted to one of an...
