Solution Overview

Problem

Existing patient repositioning systems in healthcare settings are inadequate, as they often require manual labor, which can lead to caregiver injury and do not effectively address the migration of patients towards the foot end of the bed when the head end is raised, with no commercially viable solution providing a safe, efficient, and user-friendly method for repositioning patients.

Innovation Solution

A system comprising a mattress with a movable head end piece, a sheet with beaded edges retained by spaced retainers, and a sheet receiver housing with a drive mechanism that allows the sheet to be pulled towards the head end without the need to articulate the bed, facilitating easy access for infection control and multiple repositioning operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual lifting and pulling is used to reposition patients, then repositioning can be performed, but caregiver injury risk increases

Engineering Contradiction:
Improverepositioning operationVSAvoidcaregiver injury
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical lifting and pulling with an automated mechanical system consisting of a winch, drum, and sheet arrangement. The winch winds the sheet to pull the patient toward the head end, eliminating the need for caregivers to manually lift and pull patients, thereby preventing caregiver injury while maintaining repositioning functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If prior repositioning devices are used, then patient migration is addressed, but ease of access for maintenance and infection control deteriorates

Engineering Contradiction:
Improvepatient repositioning functionVSAvoidaccess for cleaning and maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent divides the bed structure into separable components: the mattress can be removed independently from the bed frame, and the sheet can be accessed by pulling it through the headboard opening. This segmentation allows caregivers to access and clean the mattress and sheet without disassembling the entire bed or removing patients, improving ease of maintenance and infection control while maintaining repositioning reliability.

Inventive Principle:
Principle #1Segmentation

3Ease of repair

If bed articulation is required to access sheet receiver components, then components can be accessed, but operation time and complexity increase

Engineering Contradiction:
Improvecomponent accessVSAvoidaccess time
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The patent positions the sheet receiver components and winch mechanism in locations that are preliminarily prepared for easy access - the winch is mounted on the bed frame where it can be accessed by simply removing the mattress, and the sheet is arranged to be pullable through the headboard opening. This preliminary positioning eliminates the need for time-consuming bed articulation or complex disassembly procedures, allowing quick access for maintenance and sheet changes.

Inventive Principle:
Principle #10Preliminary action

AI summary

A sheet receiver for a patient repositioning system includes a housing adapted to be supported at a first end of a bed deck and a pulling device located primarily within an internal compartment of the housing. The housing has an access door adapted to open and to close so as to provide access to the internal compartment via an opening, and the housing also has an elongated slot extending along a first end thereof, and spaced from the opening. A connector has an innermost end secured to the pulling device within the internal compartment and an outermost end removably attachable to a sheet located on a mattress supported on the bed deck. The connector spans substantially the length of the slot and may include at least one window near the innermost end, to facilitate cleaning of the internal compartment. The housing includes impeding structure which prevents the inadvertent insertion of the connector and/or the sheet into the internal compartment via the opening.
