Programmable Medical Pump for Complex Multidrug Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical pumps are inadequate for managing complex multidrug therapies that require precise sequencing and varying dosages over time, posing challenges for self-administration by patients with conditions like Primary Immunodeficiency.
Innovation Solution
A programmable medical pump with a multi-day schedule and user interface that delivers sequential drug therapies, provides reminders, and uses a code sensor for medicament confirmation, allowing for remote adjustments and patient compliance tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a medical pump is designed to deliver simple single-drug therapies, then the device complexity is low and ease of operation is high, but the adaptability to complex multidrug therapies is insufficient
Solution Approach 1:
The treatment schedule is divided into multiple discrete sessions, each session containing a sequence of drug delivery protocols. The electronic memory stores these segmented treatment plans, allowing the pump to handle complex multidrug therapies through structured segmentation of treatment data into manageable units that can be systematically executed.
Solution Approach 2:
The medical pump is designed with multi-functionality to deliver different types of medicaments (e.g., immune globulin and hyaluronidase) through different administration routes (IV and subcutaneous). The system can execute various treatment protocols within a single device, making it universally applicable to complex therapies requiring multiple drugs and delivery methods.
2Measurement precision
If treatment protocols require precise sequencing of multiple drugs with varying dosages, then measurement precision is improved, but the ease of operation deteriorates due to scheduling complexity
Solution Approach 1:
The treatment schedule and protocol details are pre-programmed into the electronic memory before patient use. The complex sequencing, dosing calculations, and timing parameters are established in advance by healthcare professionals, eliminating the need for patients to manually calculate or track precise dosages during self-administration.
Solution Approach 2:
The pump provides feedback to the patient through its interface, confirming the current session, next steps, and treatment progress. This feedback mechanism guides patients through complex protocols by providing real-time information about what drug is being delivered, at what dosage, and what the next action should be, maintaining precision while simplifying operation.
3Loss of time
If patients self-administer complex therapies without supervision, then the loss of time for healthcare visits is reduced, but the reliability of proper medicament administration decreases
Solution Approach 1:
The pump enables patients to self-administer their complex therapies at home without requiring direct healthcare professional supervision during each administration. The device is programmed to guide patients through the entire process, allowing them to independently complete treatments that would otherwise require clinical setting supervision.
Solution Approach 2:
The electronic computer and treatment schedule act as an intermediary between the healthcare professional's prescription and the patient's administration actions. The programmed protocol serves as a mediator that translates complex medical orders into step-by-step instructions, ensuring reliable medicament delivery without requiring the healthcare professional to be physically present.
4Ease of operation
If the pump provides detailed guidance and reminders to patients, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The pump incorporates a user interface that provides continuous feedback to patients, including reminders of upcoming sessions, confirmation of current treatment steps, and guidance on next actions. This feedback system simplifies operation by keeping patients informed and guided throughout the complex therapy process.
Solution Approach 2:
The device integrates multiple functions including treatment delivery, scheduling management, patient guidance, and reminder capabilities within a single unified system. This multi-functionality provides comprehensive ease of operation through an integrated design that handles all aspects of complex therapy administration without requiring multiple separate devices.
