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.
