Pre-arranged Tube Organ Preservation Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In organ transplant operations, there is a need for rapid connection of tubes to the organ removed from the donor to prevent deterioration, which is challenging with a small number of people involved in the process.
Innovation Solution
An organ preservation container with a container body, through holes, joints, and tubes where the tubes are pre-arranged inside the container, allowing for quick connection to the organ's blood vessels, with adjustable connectors and plugs for adaptability to different tube diameters and organ sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple people are used to conduct organ preservation work, then the work can be completed more reliably, but the complexity of coordination and time consumption increase
Solution Approach 1:
The organ preservation container is divided into multiple independent through-holes, each equipped with its own joint and tube assembly. This segmentation allows each tube to be independently connected to different blood vessels of the organ, enabling multiple preservation functions (flushing, perfusion, ventilation) to be performed simultaneously through a single container, thereby reducing coordination complexity while maintaining reliability
Solution Approach 2:
The container body is designed with multiple through-holes that can serve different functions simultaneously - some for supplying preservation solution, others for draining, and some for gas ventilation. Each through-hole with its joint and tube assembly can be independently configured for specific vascular connections, making the single container capable of performing multiple preservation tasks that previously required multiple separate devices and personnel
2Loss of time
If tubes are connected to the organ quickly, then organ deterioration is retarded, but the connection process becomes more difficult to control precisely
Solution Approach 1:
The joints are pre-installed in the through-holes of the container body, and the tubes are pre-attached to these joints before the organ is placed in the container. This preliminary preparation eliminates the need for complex connection maneuvers during the time-critical organ transfer process. The operator simply needs to align and connect the pre-positioned tube ends to the organ's blood vessels, significantly reducing connection time while maintaining precision through the pre-established geometric relationships
Solution Approach 2:
The joint acts as an intermediary component between the container's through-hole and the tube. It provides a standardized connection interface that simplifies the coupling process. The joint includes features such as insertion holes and connection structures that guide precise alignment while enabling rapid attachment, thus mediating between the need for speed and the need for precision in tube-to-organ connection
3Ease of manufacture
If the container design is simplified, then ease of manufacture increases, but adaptability to different organ sizes and tube diameters decreases
Solution Approach 1:
The container design incorporates adjustable and configurable elements rather than fixed rigid structures. The number, position, and configuration of through-holes can be adapted based on organ size and type. Tubes of different lengths and diameters can be selected and connected to appropriate joints, allowing the same basic container design to accommodate various organs (liver, kidney, heart, etc.) without requiring completely different container designs, thus maintaining manufacturing simplicity while achieving versatility
Solution Approach 2:
The system allows for parameter changes in tube selection (length, diameter, material) and joint configuration to match different organ requirements. The container body maintains a standardized design for ease of manufacture, while the可变 parameters (tube dimensions, joint positions, through-hole configurations) can be adjusted to suit different organ sizes and vascular structures, achieving adaptability without complicating the core container manufacturing process

AI summary
An organ preservation container includes a container body, joints, and tubes. The container body includes a bottom plate and a side wall. The side wall has through holes. Each joint has a through hole. The tubes are connected to the joints from the inner side of the container body. Thus, the tubes are arranged in advance in the container body in an organ transplant operation. This enables a small number of people to speedily conduct the work of placing an organ removed from the donor in the container body and connecting the tubes to blood vessels in the organ.
