Pressure Infusion TRIZ Cases
- Syringe Receptacle Clamping Mechanism for Play-Free Dosing
Resilient clamping means with elongated holes accommodate varying plunger thicknesses while counteracting reduced pressure to prevent dosing errors.
- Dual-Channel Infusion System Fault Tolerance
A dual-channel infusion system maintains continuous medication delivery by dynamically adjusting flow rates across redundant pumps.
- Miniature Portable Infusion Device with Motor-Driven Film Compression
A miniature portable infusion device uses a direct current motor to drive a reciprocating film propping mechanism that compresses an elastic liquid container.
- Reusable Drug Dispenser Segmentation for Cost and Convenience
Segmenting the pump from disposable reservoirs reduces manufacturing costs while maintaining antiseptic fluid flow through self-sealing barriers.
- Sterile Fluid Pathway Connection for Drug Delivery Pumps
A collapsible sterile sleeve shields a piercing member inside a drug container barrel, preventing contamination while enabling precise parenteral delivery.
- Electroosmotic Pump Miniaturization via Porous Membrane
An electroosmotic pump uses a modified porous membrane to drive insulin flow with low power consumption.
- Syringe Plunger Adapter for Multi-Manufacturer Injector Compatibility
An intermediary adapter with universal mating sections resolves manufacturer-specific coupling incompatibilities to enable reliable cross-brand syringe usage.
- Mechanical Insulin Pump Actuator Design
A mechanical actuator drives a plunger to expel medication fluid from an adjustable chamber.
- Infusion Reservoir Push-On Connector for Leakage Prevention
Push-on connector assembly eliminates insulin leakage risk by removing complex threaded sleeves and O-rings from the fluid path.
- Threshold-Triggered Inserter Device for Automatic Needle Retraction
A threshold-triggered inserter device converts manual compressive force into sudden needle advancement and automatic retraction.
- IV Fluid Reservoir Pump with Pressure Valve
A reservoir pump automatically refills from an upstream source to dispense fluid through a pressure-operated valve.
- Flow Actuated Valve for MRI-Safe Implantable Infusion
A flow actuated valve closes during magnetic resonance imaging to block infusate flow, eliminating the need to empty the pump reservoir before procedures.
- Helical Track Torsion Spring Cannula Insertion
Rotating a bushing via a helical track converts linear force into controlled motion for precise tissue penetration.
- Liquid Injector Fixed Quantity Charging Unit
A liquid injector uses a fixed quantity charging unit and resilient tube to supply analgesic fluid.
- Glucose Regulation Controller with Nutrition Input
A glucose regulation controller calculates insulin delivery rates using artificial nutrition parameters.
- Thermoplastic Polyolefin Stopper with Butyl O-Ring for Medical Injection
Segmented stoppers with compressed butyl O-rings resolve sealing versus dose accuracy contradictions in medical injection devices.
- Infusion Relay Device for Constant Dose Rate
A relay device manages fluid transfer between infusion devices to maintain a stable dose rate.
- Portable Analytical Device Standardized Interface
Standardized interfaces eliminate intrinsic user components, reducing device complexity while maintaining universal compatibility.
- Enteral Feeding Pump Roller Assembly Locking Mechanism
A detachable roller assembly uses a switch member to drive locking members into positioning grooves for secure mounting on the pump main body.
- Pulse Infusion Device with Bidirectional Pump
Bidirectional pump overcomes low pressure limits by delivering high velocity pulses for effective regional anesthesia.
- Mechanically Wound Infusion Pump with Escapement Control
A mechanically wound infusion pump uses a mainspring and escapement mechanism to drive fluid delivery without electricity.
- Grooved Actuator Piston for Infusion Device Refill
A grooved actuator piston transitions fluid flow from laminar to turbulent regimes within an infusion device housing.
