Solution Overview
Problem
Existing medical pumps, such as syringe and peristaltic pumps, face challenges in delivering medical fluids accurately and consistently across varying environmental conditions while being cost-effective and user-friendly for both medical professionals and individual users.
Innovation Solution
A medical pump system incorporating a reservoir cartridge assembly with resilient membranes and a cam assembly actuated by a motor, ensuring precise fluid delivery through a camshaft synchronized with inlet and outlet valves, and a pressure sensor for occlusion detection, with durable and disposable components for cost-effective operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a training pump system is introduced to train healthcare providers on insulin pump therapy, then the ability to practice and demonstrate procedures is improved, but the risk of contamination from previous users and cross-site contamination increases
Solution Approach 1:
The patent employs disposable training cartridges that are discarded after a single use or limited number of uses. Each cartridge contains a sealed training reservoir that prevents cross-contamination between training sessions and users. The disposable nature eliminates the need for complex sterilization procedures while maintaining training effectiveness, allowing multiple students to use the same pump system without risk of contamination.
Solution Approach 2:
The training system is divided into separate, modular components: a reusable pump system and disposable training cartridges. This segmentation allows the pump to be shared across multiple training sessions while the disposable cartridges prevent contamination. Each cartridge is a self-contained unit with its own reservoir, tubing, and training fluid, isolating potential contaminants to a single-use component.
2Reliability
If realistic training materials are used to simulate actual insulin pump therapy, then the training effectiveness and realism are improved, but the complexity of the training system increases
Solution Approach 1:
The training cartridge creates a simplified copy of the actual insulin pump therapy system. It replicates the essential components (reservoir, tubing, flow path) and operational characteristics without including the full complexity of a clinical insulin pump. This allows students to practice realistic procedures on a simplified model that captures the critical aspects of pump therapy while being easier to handle and maintain.
Solution Approach 2:
By using disposable cartridges instead of permanent training devices, the system achieves realism without long-term complexity maintenance. Each cartridge is a simple, single-use component that provides realistic training functionality but requires no calibration, sterilization, or complex upkeep, thereby reducing the overall system complexity burden on training programs.
3Reliability
If a training pump system is implemented to allow hands-on practice, then the learning experience and skill development are improved, but the cost of the training system increases
Solution Approach 1:
The patent merges the reusable pump system with disposable training cartridges into an integrated training solution. The pump serves multiple training sessions while the inexpensive disposable cartridges provide the variable training materials. This combination allows the expensive pump component to be shared across many students over time, while each student receives individualized training through the disposable cartridges, distributing the cost effectively across the training program.
Solution Approach 2:
The disposable cartridges serve as the primary cost-bearing component rather than the pump system itself. Since cartridges are inexpensive and replaceable, the overall system cost is managed by making the consumable portion cheap while the capital equipment (pump) serves multiple users. This inverts the traditional cost structure where the permanent equipment is expensive and consumables are cheap, thereby reducing the barrier to implementing hands-on training programs.
