Flow Monitors TRIZ Cases
- Core Pin Assembly for Dual Valve Channels in Enteral Feeding Heads
A joined core pin assembly forms two independent valve channels and a common downstream path for compact, low-waste enteral feeding head molding.
- IV Infusion Flow Sequencing With Sensor-Guided Bag Positioning
Sensors, actuators, and a valve manifold automate IV bag positioning to keep therapeutic delivery order and flow rate accurate.
- Vision-Based Infusion Volume Detection for Closed-Loop Flow Accuracy
An external camera tracks fluid level markings to correct pump-reported infusion volume and flow rate, with alarms for severe mismatch.
- Asymmetric Roller Clamp Groove for Precise Tubing Flow Control
An off-center V-shaped groove squeezes infusion tubing more uniformly, reducing partial through-flow and improving closure precision.
- Infusion Pump Closed-Loop Catch-Up Rate for Delivery Delays
When occlusions or pauses delay infusion volume, a closed-loop catch-up rate restores planned medication delivery timing.
- Infusion Set Organizer With Electronic Drip Rate Control
Multiple infusion sets can clutter vascular intervention tables; fixing seats, detectors, and electronic controls organize sets and regulate drip rates.
- Drip Chamber Variable-Orifice Assembly for Clogging-Resistant Infusion
Learn how a short-length, variable-cross-section orifice simplifies drip chamber assembly while reducing adhesion and clogging.
- Precision Roller Clamp Groove for Fine Flow Control
A non-linear guide groove gives an infusion-set roller clamp fine flow control, stable rates, lower force, and visible occlusion.
- Infusion Flow Regulator Rotary Dial Groove Design
A rotary dial with a recessed groove regulates fluid flow through controlled width and height dimensions.
- Auto-occlusion Valve for Infusion Systems
Pressure-sensitive occlusion valve automatically blocks fluid flow when thresholds are exceeded.
- Multi-Parameter Infusion Controller for Automated Medication Dosing
A multi-parameter infusion controller adjusts medication delivery based on real-time physiological data.
- Universal Nutrition Tubing for Rotary Peristaltic Pumps
Frustoconical zones in the drip chamber allow a single nutrition tube to fit multiple pump housings, eliminating model-specific tubing variations.
- Fluid Selector With Grooved Housing For Precise Flow Rate Adjustment
A grooved housing enables accurate flow adjustment without adhesives, resolving the trade-off between device complexity and operational ease.
- Medical Connector with Integrated Self-Sealing Valve
An integrated medical connector merges interfaces into one piece, using a self-sealing valve to eliminate residual fluid exposure.
- Foot Valve Float Guidance for Drip Chamber Closure Accuracy
A foot valve uses an elastically deformable containment cage bush to guide a float obturator, ensuring precise axial movement and reliable sealing.
- Orientation-Nonspecific Sensor Port for Analyte Meters
Asymmetric conductive elements allow sensors to insert in multiple orientations, resolving the contradiction between measurement accuracy and ease of operation.
- Burette Float Valve Residual Liquid Control
A burette float valve closes the outlet when liquid drops, preventing residual retention and dilution during intravenous administration.
- Automatic Clamp System for Stable IV Injection Rate Control
An automatic clamp system adjusts medicine hose opening to maintain uniform fluid delivery through real-time drop detection.
- Microfluid Flow Meter Using Volumetric Electrode Detection
A flow measuring device uses multiple electronic circuits to detect resistance variation signals from fluid interfaces within a channel.
- Dosing Mechanism with Dual Valve Groups for Precision Fluid Control
Dual valve groups guide a translating dosing object through a pipe, resolving dose accuracy issues caused by cartridge tolerances and stopper compressibility.
- Therapeutic Injection Device Segmentation Prevents Cannula Damage
A therapeutic agent injection device uses a segmented body with separate introducer and injection ports to deliver fluid subcutaneously through a dedicated tube.
- Contrast Media Diffuser and Float Assembly for Burette Flow Control
A burette diffuser disperses contrast media flow while a segmented float ensures reliable outlet sealing.
- Integrated Bubble and Occlusion Detector for Medical Fluid Lines
Combining ultrasonic bubble detection with pressure-based occlusion sensing reduces device size while maintaining high accuracy across various tube materials.
