Deformable Blood Collection Container for Rapid Autotransfusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blood collection and infusion devices are inadequate for rapid and efficient autotransfusion in patients experiencing hemorrhagic shock, as they often require extensive processing and cannot safely and quickly collect and transfuse blood, particularly from body cavities like the pleural space, leading to increased mortality due to prolonged blood loss.
Innovation Solution
A blood collection and autotransfusion container system that includes a biocompatible, deformable container with connected infusion and transfusion members, allowing for rapid collection and transfusion of blood through gravitational or suction forces, with integrated features such as tubing fittings and accessories for efficient fluid communication and minimal processing, enabling collection and transfusion of one unit of blood in under 10 minutes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If current blood collection and infusion devices are used, then blood can be collected and transfused, but the process is slow and requires extensive processing, leading to prolonged blood loss and increased mortality
Solution Approach 1:
The patent extracts and eliminates the extensive processing steps from the blood collection and transfusion system. The container directly receives blood from body cavities and allows for immediate transfusion without intermediate processing equipment, thereby speeding up the overall process and reducing time-related mortality
Solution Approach 2:
The container is pre-configured with integrated components (collection chamber, transfusion port, tubing fittings) before use. This preliminary preparation allows the system to immediately begin collecting and transfusing blood without requiring assembly or setup time during the critical emergency situation
2Adaptability or versatility
If current devices are used for collecting blood from body cavities, then blood can be collected, but the devices cannot safely and quickly collect blood from challenging sites like the pleural space
Solution Approach 1:
The container is designed as a universal system that can collect blood from various body cavities (pleural space, pericardial space, abdominal cavity) through a single adaptable interface. The deformable container and standardized tubing fittings allow the same device to safely adapt to different anatomical sites without compromising collection reliability
3Productivity
If rapid blood transfusion is implemented, then blood loss can be reduced, but the container must be deformable and compressible to enable quick transfusion
Solution Approach 1:
The container employs deformable and compressible materials that allow dynamic change in shape and volume. The container can be compressed to expel blood rapidly during transfusion, then return to its original stable form for storage and transport, thus achieving both rapid productivity and material stability
