Wearable mCAPD System Micro-Peristaltic Pump Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dialysis systems, such as CAPD, require patients to be stationary and often inaccessible in remote areas, limiting mobility and increasing the risk of infection, while also disrupting daily life and work schedules.
Innovation Solution
A wearable mobile continuous ambulatory peritoneal dialysis (mCAPD) system featuring a micro-peristaltic pump, electronic control board, fluid bag, and sterile connector, allowing for dialysis to be performed anywhere, with automatic monitoring and alert systems to ensure infection-free and effective treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If patients use traditional CAPD system at fixed locations, then dialysis treatment can be performed, but patient mobility is restricted and daily life is disrupted
Solution Approach 1:
The dialysis system is transformed from a stationary fixed-location setup to a mobile wearable system that moves with the patient. The portable pump, fluid bags, and control unit are designed to be carried or worn by patients, enabling them to perform dialysis treatments while moving between locations, thus resolving the contradiction between treatment accessibility and patient mobility.
Solution Approach 2:
The traditional integrated dialysis machine is divided into separate modular components: a portable pump unit, fluid bags containing dialysate, tubing sets, and a control unit. This segmentation allows patients to carry only the essential components needed for treatment, significantly improving mobility while maintaining treatment effectiveness.
2Reliability
If patients travel to fixed dialysis locations, then dialysis treatment is available, but time is lost due to travel and treatment interruptions
Solution Approach 1:
The wearable mobile dialysis system enables patients to perform their own dialysis treatments independently at any location without requiring hospital facilities or specialized equipment. Patients carry their own fluid bags and pump, eliminating the need to travel to fixed dialysis centers and allowing treatment to be performed during normal daily activities, thus recovering significant time.
3Adaptability or versatility
If traditional CAPD system is used in remote areas, then dialysis treatment can be provided, but infection risk increases due to lack of sterile environment
Solution Approach 1:
The system employs disposable sterile components including pre-filled fluid bags, single-use tubing sets, and disposable filters. These pre-sterilized components eliminate the need for complex sterile preparation procedures in remote areas, allowing patients to maintain infection-free treatments anywhere while using simple, replaceable components that ensure sterility without requiring specialized facilities.
4Reliability
If hemodialysis is used, then effective kidney failure treatment is provided, but sophisticated equipment and hospital infrastructure are required
Solution Approach 1:
The complex mechanical and electronic systems of traditional hemodialysis machines are replaced with a simple portable peristaltic pump that uses mechanical rotation to control fluid flow. This mechanical substitution eliminates the need for sophisticated equipment, power-intensive components, and hospital infrastructure, while still providing effective continuous ambulatory peritoneal dialysis treatment for kidney failure patients.

AI summary
A wearable mobile continuous ambulatory peritoneal dialysis (mCAPD) system, includes an mCAPD module mounted on a front portion of a wearable belt, wherein the mCAPD module comprises a micro-peristaltic pump disposed in a corresponding front portion, and an electronic control board connected to the micro-peristaltic pump for controlling and managing the mCAPD process, a fluid bag containing a dialysate fluid, attached to the wearable belt and to the electronic control board, and a sterile connector having a tube portion fixed into a guide section of the micro-peristaltic pump, and a first connecting end for connecting to a first tube inserted into a peritoneum cavity of the human body, and a second connecting end for connecting to a second tube attached to the fluid bag. Upon rotation, the micro-peristaltic pump enables a flow of fluid between the peritoneum cavity and the fluid bag.
