Bedridden Patient Positioning Pad With Disposable Turning Sections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for positioning bedridden patients are cumbersome, requiring multiple caregivers to turn patients safely and comfortably, leading to caregiver strain and increased institutional care, as they often lack effective support, easy handling, and disposable options.
Innovation Solution
A pad or sheet member with integrated straps or turning means, handles, and a waterproof, cushioned design with separable sections and absorbent layers, allowing single caregiver operation, secure attachment to bedrails, and easy disposal of soiled parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional straps or sheet members are used to position bedridden patients, then the patient can be turned to the side, but multiple caregivers are required which increases device complexity and reduces ease of operation
Solution Approach 1:
The device is divided into a pad member and a separate sheet member that can be used independently or together. The pad member provides core support functionality while the sheet member adds positioning capability, allowing flexible deployment based on patient needs and caregiver availability.
Solution Approach 2:
The pad member acts as an intermediary element between the patient and the sheet member. It provides a stable base that simplifies the interaction between the caregiver and patient, enabling single-caregiver operation through its wedge shape and integrated handling features.
2Ease of operation
If manual rolling of patients is performed without proper support, then patient positioning can be achieved, but caregiver back strain and injury occur
Solution Approach 1:
The pad member is positioned under the patient before the turning operation begins, providing pre-positioned support and cushioning. This advance preparation distributes the patient's weight and reduces the physical strain on the caregiver during the actual rolling motion.
Solution Approach 2:
The pad member serves as a mechanical intermediary that bears the patient's weight and facilitates the turning motion. Instead of the caregiver directly supporting the patient's full weight, the pad member mediates the force distribution, protecting the caregiver's back.
3Reliability
If pillows are used to prop patients in side position, then patient support is achieved, but the device lacks integration and requires multiple separate elements
Solution Approach 1:
The pad member and sheet member are designed to work together as an integrated system. The pad member's wedge shape provides inherent positioning stability while the sheet member's straps secure the arrangement, combining support and positioning functions into a unified device that reduces the need for separate pillows and positioning aids.
4Reliability
If frequent patient turning is required to prevent bedsores, then patient health is improved, but the frequency of manipulation increases caregiver strain
Solution Approach 1:
The pad member provides pre-positioned cushioning and support before each turning operation, making frequent repositioning less physically demanding. This advance preparation allows caregivers to perform multiple turnings throughout the day with reduced cumulative strain.
Solution Approach 2:
The wedge-shaped pad member and sheet member combination is designed to facilitate patient turning with minimal caregiver intervention. Once positioned, the device maintains patient stability, allowing the patient to remain in the repositioned state longer and reducing the frequency and intensity of caregiver interventions.

AI summary
A bedridden individual positioning device, the device having a pad member with at least two sets of turning members attached on its sides and at least one line of perforations or the like extending laterally across the pad member such that the lower portion of the pad member can be separated from the remainder portion if the lower portion becomes soiled.
