Sophisticated medical drug dosing system
designing an innovative drug delivery system that would substantially reduce consumable costs associated with traditional syringe-screw mechanisms. This complex project required creative problem-solving, thorough research, and advanced engineering expertise. The resulting proof of concept demonstrated remarkable efficacy and significant cost-reduction potential at scale, positioning it as a potentially transformative solution for the pharmaceutical delivery sector
This medical drug dosing system is an innovative drug delivery mechanism designed to replace traditional syringe-screw mechanisms with a more cost-effective solution.
Key features include:
- Miniature peristaltic pump design with continuous flow capability
- Low energy consumption (0.054 mW during operation)
- Compact form factor (17-20mm outer diameter)
- Four-roller (180° structure) mechanism for reliable liquid transfer
- Silicone tube-based system (OD 1.8mm, ID 0.6mm)
- Precise flow control from 30 μL/hr (0.0083 μL/s) to 1800 μL/hr (0.5 μL/s)
- Ability to overcome pressures up to 3.6 bar
- 8mm brushless BLDC motor with planetary gearhead (1:256 or 1:1024 ratios)
- Digital control interface with direction control and speed settings
- Separate rolling unit (power converter) and consumable components for cost efficiency
The system was successfully demonstrated as a proof of concept, showing potential for significant cost reduction in pharmaceutical delivery applications while maintaining required performance specifications.
