Compact Mini Air Pump for Intermittent Pneumatic Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air pumps for intermittent pneumatic compression therapy are limited by their size, AC power requirements, and lack of portability, which increases the risk of deep vein thrombosis during extended periods of inactivity, especially in patients who need to be moved between locations, and they do not allow for customizable compression settings for different body parts.
Innovation Solution
A compact, portable mini air pump powered by either DC battery or AC electricity, with user-operated controls and sensors to maintain specific air pressure levels, allowing for customizable therapy settings for limb or foot treatments, and featuring a dual-output electromechanical valve and air pressure sensor to ensure safe and effective compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional air pumps are used for intermittent pneumatic compression therapy, then compression therapy can be provided, but the device size is large and portability is limited
Solution Approach 1:
The pump is divided into separate functional modules: a compressible chamber that can be manually squeezed, a valve mechanism, and an air delivery system. This segmentation allows the compression function to be separated from the power source, enabling portable use without requiring a large integrated motor housing.
Solution Approach 2:
A flexible air tube serves as an intermediary between the manual compression chamber and the treatment garment. This allows the pump mechanism to be physically separated from the compression application point, enabling the user to compress the chamber remotely while the garment remains on the patient's limb.
2Ease of operation
If traditional air pumps are used for intermittent pneumatic compression therapy, then compression can be delivered, but AC power requirements limit use during patient mobility
Solution Approach 1:
The system uses manual self-compression by the user or caregiver rather than requiring external electrical power. The human operator provides the mechanical energy needed to inflate the chamber, eliminating dependence on AC power outlets and enabling therapy during patient relocation or in mobile settings.
Solution Approach 2:
The compression chamber is inflated through periodic manual compression cycles rather than continuous motor operation. This intermittent manual pumping mimics the natural physiological compression patterns and eliminates the need for continuous electrical power supply.
3Adaptability or versatility
If standardized compression settings are used, then device complexity is reduced, but customizable compression settings for different body parts cannot be provided
Solution Approach 1:
The system allows dynamic adjustment of compression parameters including inflation pressure, compression duration, and cycle frequency. Users can modify these settings based on the specific body part being treated (e.g., calf vs. thigh) and patient requirements, transforming a static device into an adaptable therapy system.
Solution Approach 2:
The compression characteristics are controlled by changing physical parameters such as chamber volume, compression force applied by hand, and timing of compression cycles. These parameter adjustments provide customization for different anatomical regions without requiring complex electronic control systems or multiple pre-programmed settings.

AI summary
A compact mini air pump includes a rectangular, box-shaped body having a standard AC power cord extending from it, two air supply output ports, and a control and information panel with user-operated buttons and status lights located on its front side. Within the hollow interior of the body is an air compressor, a dual-output electromechanical valve having to two air output tubes, an air pressure sensor, a DC battery power supply, an AC power connection, and an electronic circuit board controlling the mini air pump's function. The air supply output ports, an extension of the air tubes within the body, supply air to Intermittent Pneumatic Compression (“IPC”) Therapy device garments through flexible air supply tubes. The mini air pump device is sized to be held by one hand for portability.
