Equine Peristaltic Pneumatic Compression Device for Laminitis Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laminitis in equines is a debilitating condition caused by vascular disease at the arteriovenous junction within the hoof, leading to severe pain, edema, and potential euthanasia due to the lack of effective circulatory treatments specifically designed for hooved animals.
Innovation Solution
A modified peristaltic pneumatic compression device adapted for equines, featuring a wrap design with larger bore tubing, an interposed compressor chamber, and a rapid compression/decompression cycle to improve circulation and alleviate edema, pain, and inflammation, incorporating a fleece lining and quick-release Velcro fasteners for comfort and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression device is used to treat venous stasis and edema, then circulation is improved and swelling is reduced, but the device complexity increases and requires specialized adaptation for equine anatomy
Solution Approach 1:
The compression device is divided into multiple inflatable chambers arranged along the leg, allowing segmented compression of different regions. This segmentation enables targeted treatment of venous stasis in specific areas while maintaining overall circulation improvement, and the modular chamber design facilitates adaptation to equine leg anatomy.
Solution Approach 2:
The device employs dynamic compression through sequential inflation and deflation of chambers, creating a wave-like motion that mimics natural muscle pumping action. This dynamic approach enhances venous return and lymphatic drainage more effectively than static compression, while the programmable control system allows adjustment of compression patterns to match equine physiological needs.
2Productivity
If rapid compression and decompression cycles are implemented, then edema and pain are alleviated more quickly, but the device requires larger bore tubing and interposed compressor chambers increasing complexity
Solution Approach 1:
The device includes pre-positioned interposed compressor chambers and larger bore tubing designed to enable rapid filling and emptying of compression chambers. This preliminary structural preparation allows the system to deliver fast compression-decompression cycles without requiring complex active control mechanisms during operation, as the physical design itself facilitates rapid response.
Solution Approach 2:
Interposed compressor chambers act as intermediaries between the air source and the compression chambers, buffering and regulating air delivery to enable rapid compression cycles. These intermediary components smooth out pressure fluctuations and allow fast response times while protecting the system from excessive pressure spikes, effectively mediating between the power source and the treatment delivery mechanism.
3Loss of time
If the device is designed for rapid treatment of laminitis episodes, then the duration and severity are reduced, but quick-release fasteners and specialized wrapping mechanisms increase manufacturing complexity
Solution Approach 1:
The device incorporates self-adjusting features including automatic tensioning mechanisms and self-aligning components that reduce the need for complex manual adjustment mechanisms. The quick-release fasteners are designed to automatically engage and disengage without requiring complex tools or procedures, enabling rapid application and removal while maintaining structural integrity through simple, manufacturable designs.
4Ease of operation
If fleece lining and comfort features are added for equine safety, then animal comfort and compliance improve, but the device weight and material usage increase
Solution Approach 1:
The fleece lining and comfort features are applied locally to specific contact areas where the device interfaces with the equine leg and hoof, rather than covering the entire device structure. This localized approach provides necessary comfort and safety where needed while minimizing overall material usage and device weight, allowing the structural components to remain lightweight and easy to handle.

AI summary
A system and methodology for treatment of circulation related conditions in hooved animals such as laminitis in horses. The methodology employs a garment wrap that is releasably secured to the animal's leg. The wrap includes several inflatable chambers, one of which, the most distal one, engages the frog and bulbar sections of the horses hoof. The methodology calls for the pressuring of the inflatable chambers in accordance with a sequence that prevents backflow from a more proximal point on the animal's leg to a more distal point on the leg. A boot arrangement including an inner sole pad are also utilized both during the therapy procedure and afterwards. The inner sole pad can provide related medications and can be used in an iontophoresis procedure.
