Disposable Patient Lifting Sling with Biodegradable Fabric
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting slings, often made of woven fabrics, have complex structures and high costs, leading to difficulties in preventing cross-infection between patients and are not effectively sanitized, resulting in increased costs and potential loss during transport.
Innovation Solution
A manual lifting sling apparatus with a simple, cost-effective design featuring a bottom support, rear support, and side blocking parts made from woven or nonwoven fabric, with breathable biodegradable or non-biodegradable materials, and reinforced edges, allowing for dedicated use and easy identification to prevent cross-infection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lifting slings are made of woven fabrics with complex structure, then the lifting function is achieved, but the cost increases and cross-infection prevention becomes difficult
Solution Approach 1:
The patent employs disposable nonwoven fabric slings instead of reusable woven fabric slings. Each sling is designed for single use and then discarded, eliminating the need for washing and sterilization processes. This disposable approach directly prevents cross-infection between patients while using simpler, cheaper nonwoven material construction rather than complex woven structures.
2Reliability
If lifting slings are washed at high temperature to kill organisms, then cross-infection is prevented, but the slings are destroyed
Solution Approach 1:
Instead of attempting to sanitize and reuse the slings through high-temperature washing, the patent adopts a disposable approach where each sling is used once and then discarded. This eliminates the contradiction entirely by removing the need for sanitization processes that would destroy the fabric, while still preventing cross-infection through single-use designation.
3Reliability
If sufficient spare slings are prepared for washing and transport, then cross-infection is prevented, but the cost increases
Solution Approach 1:
The patent uses inexpensive nonwoven fabric slings designed for single use. Because each sling is so cheap to produce, hospitals can afford to provide a fresh sling for each patient without needing to maintain large inventories of spare slings for washing and transport. The low cost per unit allows direct disposal after use, eliminating the need for complex logistics of managing multiple spare slings.
4Ease of manufacture
If lifting slings are made of nonwoven fabric with simple structure, then cost is reduced, but the ability to withstand washing and transport is reduced
Solution Approach 1:
The patent accepts the reduced durability of simple nonwoven fabric construction because the slings are designed for single use only. There is no need for the material to withstand repeated washing and transport stresses. This disposable approach allows the use of the simplest, cheapest nonwoven fabric construction without compromising reliability, since each sling is used once and then discarded rather than reused.

AI summary
Disclosed is a manual lifting sling apparatus (10) made of fabric, comprising: a bottom support part (12) used for supporting the buttocks and legs of a patient; a rear support part (11) joined to the bottom support part (12) to form an inclined angle and used for supporting the back of the patient; a left blocking part (13) and a right blocking part (14) restraining the patient respectively on the left and right sides, the left blocking part (13) and the right blocking part (14) both concurrently being joined with the bottom support part (12) and the rear support part (11); and at least two lifting handles (15) provided on both the left blocking part (13) and the right blocking part (14). The fabric used for the apparatus is a woven fabric or non-woven fabric, and is made of a non-biodegradable material or biodegradable polymer material. The apparatus has a simple structure, a rational design, a high degree of comfort and is low in cost, and can be a manual lifting sling apparatus deployed specially for each patient for finite use.
