Solution Overview

Problem

Current pneumatic compression therapy devices for deep vein thrombosis (DVT) are limited by ease of use, patient comfort, and economic factors, primarily due to complex operation and high costs, which affect compliance and effectiveness.

Innovation Solution

A disposable pouch designed for receiving an inflatable compression sleeve, featuring a reversible insertion slit and fastening mechanism for easy attachment to a limb, combined with an inflatable compression sleeve having a trapezoid or annulus angular section shape, allowing for improved blood circulation and reduced operational complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional compression device with multiple components is used, then compression therapy function is achieved, but device complexity and cost increase

Engineering Contradiction:

Improvecompression therapy effectivenessVSAvoiddevice structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the compression sleeve, pouch, and fastening mechanisms into a single integrated disposable unit. The pouch contains the compression sleeve and includes lateral edge fastening portions that directly attach to the limb, eliminating the need for separate application tools or multiple components. This merging reduces device complexity while maintaining compression therapy effectiveness.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The disposable pouch serves multiple functions: it contains the compression sleeve, provides the fastening mechanism through lateral edge portions, and acts as the application interface to the limb. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while maintaining therapeutic reliability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If a complex compression device with multiple steps is used, then adequate compression is achieved, but ease of operation decreases

Engineering Contradiction:

Improvecompression therapy effectivenessVSAvoidease of use

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The compression sleeve is pre-loaded into the pouch during manufacturing, and the pouch is pre-formed with lateral edge fastening portions. This preliminary preparation eliminates the need for complex assembly steps at the point of use, allowing healthcare providers to simply attach the pre-assembled unit to the patient's limb, thereby improving ease of operation while maintaining compression effectiveness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The disposable pouch with integrated fastening mechanisms is designed to be self-applied to the limb without requiring additional tools or complex procedures. The lateral edge fastening portions directly attach to the limb surface, enabling the device to serve itself in the application process, which significantly improves ease of operation.

Inventive Principle:

Principle #25Self-service

3Reliability

If expensive compression devices are used, then therapy effectiveness is maintained, but economic cost increases

Engineering Contradiction:

Improvecompression therapy effectivenessVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent employs a disposable pouch-compression sleeve unit that is manufactured at low cost and used once. This disposable approach eliminates the need for expensive, reusable devices with complex mechanisms. The simple structure of the pouch with lateral edge fastening portions allows for cost-effective manufacturing while maintaining compression therapy effectiveness during its use period.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The compression system is segmented into a simple pouch structure containing the compression sleeve, with fastening functions separated into lateral edge portions. This segmentation allows each component to be manufactured independently using simple, cost-effective processes, reducing overall manufacturing cost while maintaining the reliability of the compression therapy function.

Inventive Principle:

Principle #1Segmentation

AI summary

A disposable pouch for receiving an inflatable compression sleeve, an inflatable compression sleeve, a system, and a method to use the system, for use in pneumatic compression therapy. The pouch comprising a first sheet superposed to a second sheet adjoined to form a cavity and an insertion slit for allowing reversible insertion of the inflatable compression sleeve into the cavity; a lateral edge fastening portion of the first sheet being configured to cooperate with an opposite lateral edge fastening portion of the second sheet when the pouch is wrapped in a conoid configuration for allowing releasable attachment to a limb of a user; and a flap configured to reversibly close the insertion slit and secure the inflatable compression sleeve. The inflatable compression sleeve comprising a first face superposed to a second face each made of an airtight material, being adjoined to form a plurality of adjacent inflatable pockets extending transversely across the inflatable compression sleeve, and a plurality of tubes each coupled at a first end to one of the inflatable pockets and at a second end to an inflating device connector.
