Tube-Docking Holding Device for Peritoneal Dialysis Hygiene
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients with physical limitations, such as vision loss or hand tremors, face challenges in safely docking and disconnecting catheters and dialysate tubes during peritoneal dialysis, risking contamination and infection due to the difficulty in maintaining hygiene and avoiding dust and bacteria.
Innovation Solution
A tube-docking holding device with a first and second connector bracket, featuring a double-shell structure and cap bushing, that securely docks and isolates the sterile ends of the catheter and dialysate tube, allowing for easy connection and disconnection without direct contact, thereby reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the patient directly docks the catheter with the dialysate tube, then the operation is simple and quick, but the risk of contamination and infection increases due to difficulty in maintaining hygiene and avoiding dust and bacteria
Solution Approach 1:
The patent introduces a docking device as an intermediary tool between the catheter and dialysate tube. This device includes a receiving cavity that holds the catheter connector and a docking structure that interfaces with the dialysate tube connector, allowing the patient to dock components without direct hand contact with the sterile connectors, thus maintaining hygiene while simplifying the operation for patients with physical limitations
Solution Approach 2:
The docking device is segmented into distinct functional components: a body structure with a receiving cavity for the catheter connector, a docking structure for the dialysate tube connector, and a cap structure. This segmentation allows each component to perform its specific function while maintaining overall simplicity of use
2Reliability
If the patient uses a complex docking device to prevent contamination, then hygiene safety is improved, but the ease of operation deteriorates due to difficulty in handling for patients with vision loss or hand tremors
Solution Approach 1:
The docking device incorporates a cap structure that can be automatically engaged with the receiving cavity when the catheter connector is inserted. This self-service mechanism reduces the need for precise manual manipulation, allowing patients with vision loss or hand tremors to dock the catheter safely without complex manual operations
Solution Approach 2:
The docking device uses a cap structure that can flexibly cover and protect the catheter connector. The cap can be easily opened and closed, providing a simple tactile interface for patients to understand the docking status without requiring visual acuity, thus improving ease of operation while maintaining contamination prevention
3Object-affected harmful factors
If the docking site is covered and isolated, then the risk of dust and bacteria entry is reduced, but the device structure becomes more complex
Solution Approach 1:
The docking device employs a nested structure where the catheter connector is received within a cavity in the body structure, and the cap structure can be placed over the receiving cavity. This nested arrangement provides multiple levels of protection against dust and bacteria entry while maintaining a compact and relatively simple overall device structure

AI summary
A tube-docking holding device includes a first connector bracket and a second connector bracket. The first connector bracket includes two shells. When the two shells are closed, a first accommodation space is surrounded for fixing a portion of a first connector assembly of a catheter. The second connector bracket includes a base body and a cover body. The base body includes a first inner shell and a first outer shell. The cover body includes a second inner shell and a second outer shell. When the cover body and the base body are closed, the first inner shell and the second inner shell surround and define a second accommodation space for fixing a portion of a second connector assembly of a dialysate tube. An interconnected guiding space is formed between the first inner shell and the first outer shell and between the second inner shell and the second outer shell.
