Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peritoneal dialysis systems require an external power source and heating devices to warm the dialysis solution to the necessary temperature, limiting patient mobility and independence.
Innovation Solution
A self-warming peritoneal dialysis solution bag equipped with a non-electric warming patch that undergoes an exothermic chemical reaction, such as iron oxidation, to heat the solution to at least 35°C (95°F) without the need for external power or heating sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an external electric heating pad and power source are used to heat the dialysis solution, then the solution can be heated to the required temperature, but patient mobility is limited and external devices are required
Solution Approach 1:
The warming patch contains all necessary components (heat-producing composition and activating solution) within the bag system itself, allowing the solution to be heated without external power sources or heating devices. The patient simply needs to activate the patch by rupturing the frangible seal, making the system self-sufficient and portable.
Solution Approach 2:
The warming patch is integrated directly into the dialysis solution bag, with the heat-producing composition and activating solution nested within the same container structure. This integration eliminates the need for separate external heating devices and allows the heating function to be embedded within the portable bag system.
2Temperature
If an external power source and heating pad are required, then the solution can be heated, but the patient must remain at a fixed location with access to power
Solution Approach 1:
The system uses a self-contained chemical heating mechanism that requires no external power source. The warming patch generates heat through an exothermic chemical reaction between the heat-producing composition and activating solution, enabling the patient to perform dialysis treatment at any location without needing access to electrical outlets or heating equipment.
Solution Approach 2:
The patent replaces the mechanical/electric heating system (heating pad and power source) with a chemical system (exothermic reaction between heat-producing composition and activating solution). This substitution eliminates the need for electrical infrastructure and enables greater location flexibility for the patient.
3Temperature
If a non-electric warming patch with sufficient activatable agent is used, then the solution can be heated to at least 35°C without external power, but the patch must contain enough chemical reactants to generate adequate heat
Solution Approach 1:
The system optimizes the concentration and quantity of the heat-producing composition and activating solution to ensure that the exothermic reaction generates sufficient heat to warm the dialysis solution to at least 35°C. The formulation is designed to achieve the required temperature increase while containing all necessary reactants within the portable bag structure.

AI summary
A self-warming peritoneal dialysis solution bag (20) is provided that contains a peritoneal dialysis solution. The solution bag (20) can have an outer surface and a non-electric, warming patch (32, 34) adhered or affixed to the outer surface. The non-electric, warming patch (32, 34) can include an activatable agent that undergoes an exothermic reaction when activated. The warming patch (32, 34) can retain a sufficient amount of activatable agent to generate enough heat, upon activation, to warm the contents of the bag (20) to at least 95°F. Warming patches that are separate from a peritoneal dialysis solution bag are also provided, as are kits for warming a peritoneal dialysis solution bag. Methods of warming a peritoneal dialysis solution bag with a non-electric, warming patch, are also provided.
